Psychology



psychology, science or study of the thought processes and behavior of humans and other animals in their interaction with the environment. Psychologists study processes of sense perception, thinking, learning, cognition, emotions and motivations, personality, abnormal behavior, interactions between individuals, and interactions with the environment. The field is closely allied with such disciplines as anthropology and sociology in its concerns with social and environmental influences on behavior; physics in its treatment of vision, hearing, and touch; and biology in the study of the physiological basis of behavior. In its earliest speculative period, psychological study was chiefly embodied in philosophical and theological discussions of the soul.



Development of Modern Psychology

The De anima of Aristotle is considered the first monument of psychology as such, centered around the belief that the heart was the basis for mental activity. The foundations of modern psychology were laid by 17th-century philosopher Thomas Hobbes, who argued that scientific causes could be established for every sort of phenomenon through deductive reasoning. The mind-body theories of Rene Descartes, Baruch Spinoza, and G. W. Leibniz were equally crucial in the development of modern psychology, where the human mind's relation to the body and its actions have been significant topics of debate.

In England the empirical method employed in modern psychological study originated in the work of John Locke, George Berkeley, Thomas Reid, and David Hume. David Hartley, James Mill, John Stuart Mill, and Alexander Bain stressed the relation of physiology to psychology, an important development in the scientific techniques of modern psychology. Important contributions were made in the physiological understanding of human psychology by French philosopher Condillac, F. J. Gall, the German founder of phrenology, and French surgeon Paul Broca, who localized speech centers in the brain.

In the 19th cent., the laboratory work of Ernst Heinrich Weber, Gustave Fechner, Wilhelm Wundt, Hermann von Helmholtz, and Edward Titchener helped to establish psychology as a scientific discipline—both through the use of the scientific method of research, and in the belief that mental processes could be quantified with careful research techniques. The principle of evolution, stemming from Charles Darwin's theory of natural selection, gave rise to what became known as dynamic psychology. The new approach, presented by American psychologist William James in his Principles of Psychology (1890), looked at consciousness as an evolutionary process.

Out of the new orientation in psychology grew the clinical experiments in hysteria and hypnotism carried on by J. M. Charcot and Pierre Janet in France. Sigmund Freud, in his influential theory of the unconscious, gave a new direction to psychology and laid the groundwork for the psychoanalytic model. Freudian theory took psychology into such fields as education, anthropology, and medicine, and Freudian research methods became the foundations of clinical psychology.

The behaviorism of American psychologist John B. Watson was highly influential in the 1920s and 30s, with its suggestion that psychology should concern itself solely with sensory stimuli and behavioral reaction. Behaviorism has been important in modern psychology, particularly through the work of B. F. Skinner since the 1930s.

Equally important was the development of Gestalt psychology by German psychologists Kurt Koffka, Wolfgang Köhler, and Max Wertheimer. Gestalt theory contended that the task of psychology was to study human thought and behavior as a whole, rather than breaking it down into isolated instances of stimulus and response.

Another influential school of psychology was developed in the 1950s and 60s by Abraham Maslow and Carl Rogers. Their humanistic theory asserts that people make rational, conscious decisions regarding their lives, and optimistically suggests that individuals tend to reach toward their greatest potential.





Modern Psychology

Modern psychology is divided into several subdisciplines, each based on differing models of behavior and mental processes. Psychologists work in a number of different settings, including universities and colleges, primary and secondary schools, government agencies, private industry, hospitals, clinics, and private practices. Recent years have seen a rise in the significance of applied psychology—as can be seen from the areas contemporary psychologists concern themselves with—with an attendant decline in the importance of psychology in academia. In the United States, clinical psychology has become a significant focus of the discipline, largely separate from psychological research. Clinical psychologists are responsible for the diagnosis and treatment of various psychological problems.

Biological models of behavior have become increasingly prominent in psychological theory, particularly with the development of various tools—such as the positron emission tomography (PET) scan—for mapping the brain. The field of neuropsychology, which studies the brain and the connected nervous system, has been an outgrowth of this contemporary focus on biological explanations of human thought and behavior. Cognitive models, derived from the Gestalt school of psychology, focus on the various thinking processes which mediate between stimuli and responses.

Educational psychology, derived from the 18th and 19th cent. educational reforms of Friedrich W. Froebel, Johann Pestalozzi, and their follower Johann Herbart, was later expanded by G. Stanley Hall and by E. L. Thorndike. It is concerned with the development of improved methods of teaching and learning.

Social psychology, developed by British psychologists William McDougall and Havelock Ellis, studies the effects of various social environments on the individual. Some other branches of the field include developmental psychology, which studies the changes in thought and behavior through the course of life; experimental psychology, which is the laboratory research involved in the understanding of the mind; and personality psychology, which deals specifically with individual personality and the processes by which it is formed.

In recent years a number of new fields of psychology have emerged. Industrial/organizational psychology, emerging from social psychology, focuses on the workplace and considers such topics as job satisfaction, leadership, and productivity. Health psychology examines how psychological factors contribute to pathology, and demonstrates how psychology can contribute to recovery and illness prevention for such somatic disorders as heart disease, cancer, and diabetes. In environmental psychology, research focuses on how individuals react to their physical environments, and suggests improvements which may be beneficial to psychological health. Other new areas of psychology include counseling psychology, school psychology, forensic psychology, and community psychology

Psychology and Psychiatry


adolescence

adolescence, time of life from onset of puberty to full adulthood. The exact period of adolescence, which varies from person to person, falls approximately between the ages 12 and 20 and encompasses both physiological and psychological changes. Physiological changes lead to sexual maturity and usually occur during the first several years of the period. This process of physical changes is known as puberty, and it generally takes place in girls between the ages of 8 and 14, and boys between the ages of 9 and 16. In puberty, the pituitary gland increases its production of gonadotropins, which in turn stimulate the production of predominantly estrogen in girls, and predominantly testosterone in boys. Estrogen and testosterone are responsible for breast development, hair growth on the face and body, and deepening voice. These physical changes signal a range of psychological changes, which manifest themselves throughout adolescence, varying significantly from person to person and from one culture to another. Psychological changes generally include questioning of identity and achievement of an appropriate sex role; movement toward personal independence; and social changes in which, for a time, the most important factor is peer group relations. Adolescence in Western societies tends to be a period of rebellion against adult authority figures, often parents or school officials, in the search for personal identity. Many psychologists regard adolescence as a byproduct of social pressures specific to given societies, not as a unique period of biological turmoil. In fact, the classification of a period of life as “adolescence” is a relatively recent development in many Western societies, one that is not recognized as a distinct phase of life in many other cultures.




aggression

aggression, a form of behavior characterized by physical or verbal attack. It may appear either appropriate and self-protective, even constructive, as in healthy self-assertiveness, or inappropriate and destructive. Aggression may be directed outward, against others, or inward, against the self, leading to self-destructive or suicidal actions. It may be driven by emotional arousal, often some form of frustration, or it may be instrumental, when it is used to secure a reward.

Sigmund Freud postulated (1920) that all humans possessed an aggressive drive from birth, which, together with the sexual drive, contributed to personality development, and found expression in behavior. Austrian ethologist Konrad Lorenz suggested that aggression was innate, an inherited fighting instinct, as significant in humans as it was in other animals. He contended that the suppression of aggressive instincts, common among human societies, allows these instincts the chance to build up, occasionally to the point where they are released during instances of explosive violence. Many psychoanalysts have argued against these theories, which see aggression as a primary drive, offering the possibility that aggression may be a reaction to frustration of primary needs. In the late 1930s, John Dollard argued that any sort of frustration inevitably led to an aggressive response.

More recently, Albert Bandura has performed studies that indicated that aggression is a learned behavior. Using children in his studies, Bandura demonstrated that, by watching another person act aggressively and obtain desirable rewards or by learning through personal experience that such behavior yields rewards, aggression can be learned. Leonard Berkowitz has contended that all animals learn the most effective response to an aversive occurence (one where the expected reward is denied), whether it be attack or flight. A number of psychologists contend that children and adolescents are vulnerable to media portrayals of violence, particularly in film and television. Popular media tends to depict violence as relatively common, and generally effective. Anonymity may facilitate aggression: when an individual is part of a large group, he may be more likely to elicit aggressive behavior, in a process known as deindividuation.

Recent research on the biological basis of aggression has sought to show that genetic factors may be responsible for aggressive behavior. In the 1970s it was suggested that men who were born with an extra Y chromosome were likely to display more episodes of aggressive behavior than men who were not born with this extra chromosome. Still, conclusive proof has yet to be found for a genetic theory of aggression.

Other factors, including learning difficulties, minimal brain damage, brain abnormalities—such as temporal lobe epilepsy—and such social factors as crowding and poverty have been suggested to have contributed in certain cases to exaggeratedly aggressive behavior. Psychological investigation into aggressive behavior continues, with significant corrolary studies being performed in endocrinology—to determine whether hormonal imbalances have an impact on behavior—and in primate research. Each theory may be accurate in part, since aggression is believed to have a number of determining factors.




ambivalence

It is coexistence of two opposing drives, desires, feelings, or emotions toward the same person, object, or goal. The ambivalent person may be unaware of either of the opposing wishes. The term was coined in 1911 by Eugen Bleuler, to designate one of the major symptoms of schizophrenia, the others being autism and disturbances of affect (i.e., emotion) and of association (i.e., thought disorders). Bleuler felt that there were normal instances of ambivalence, such as the feeling, after performing an action, that it would have been better to have done the opposite; but the normal person, unlike the schizophrenic, is not prevented by these opposing impulses from deciding and acting. In Freudian psychoanalysis, ambivalence was described as feelings of love and hate toward the same person. This specific meaning has attained common usage by psychiatrists and psychoanalysts.




amnesia

It is the condition characterized by loss of memory for long or short intervals of time. It may be caused by injury, shock, senility, severe illness, or mental disease. Some cases of amnesia involve the unconscious suppression of a painful experience and everything remindful of it including the individual's identity (see defense mechanism). Retrograde amnesia is loss of memory of events just preceding temporary loss of consciousness, as from head injury; it is evidence that memory proceeds in two stages, short term and long term. One form of the condition known as tropic amnesia, or coast memory, affecting white men in the tropics, is probably a variety of hysteria. Aphasia of the amnesic variety is caused by an organic brain condition and is not to be confused with other forms of amnesia. To cure amnesia, attempts are made to establish associations with the past by suggestion, and hypnotism is sometimes employed.



anxiety

anxiety, anticipatory tension or vague dread persisting in the absence of a specific threat. In contrast to fear, which is a realistic reaction to actual danger, anxiety is generally related to an unconscious threat. Physiological symptoms of anxiety include increases in pulse rate and blood pressure, accelerated breathing rates, perspiration, muscular tension, dryness of the mouth, and diarrhea. Freud postulated that anxiety was a result of repressed, pent-up sexual energy, but later came to view it as a danger signal alerting the ego to excessive stimulation and causing repression. Anxiety disorders include observable, overt anxiety, as well as phobias and other conditions where a defense mechanism has been set up to disguise the anxiety from both the sufferer and the observer. In generalized anxiety, the individual experiences long-term anxiety with no explanation for its cause; such a condition may be called free-floating, since it is not linked to a specific stimulus. Panic disorder involves sudden anxiety attacks which are manifested in heart palpitations, shortness of breath, or fainting. The individual with a phobic disorder can identify the stimulus that causes anxiety: such stimuli as enclosed space, heights, and crowds become imbued with greatly exaggerated anxiety and are carefully avoided by the phobic individual. Obsessive-compulsive disorders (OCD) are characterized by obsessions (mental quandries) and compulsions (physical actions) that engage the individual excessively. Extreme anxiety may be experienced if the person does not carry out the compulsion or attempts to ignore the obsession. Post-traumatic stress disorder occurs when an individual has recurrent dreams, flashbacks, or panic attacks after a particularly traumatic experience.




aphasia

language disturbance caused by a lesion of the brain, making an individual partially or totally impaired in his ability to speak, write, or comprehend the meaning of spoken or written words. It is distinguished from functional disorders such as stammering or stuttering, and from impaired speech due to physical defects in the organs used for speaking. Treatment consists of reeducation; the oral and lip-reading methods employed in the education of deaf and mute children have been found to be of assistance in therapy.



association

association, in psychology, a connection between different sensations, feelings, or ideas by virtue of their previous occurrence together in experience. The concept of association entered contemporary psychology through the empiricist philosophers John Locke, George Berkeley, David Hume, and David Hartley, and the British associationist school of James Mill, John Stuart Mill, and others (see associationism). Translated into the stimulus-response terms of behaviorism, association has been thought of as the basis of learning and conditioning. Paired experience and the principle of reinforcement are often invoked to explain associative learning. However, Gestalt psychologists, who believe that association between items is dependent on their relations to each other, interpret association as an aftereffect of perceptual organization. Psychoanalysis uses a technique known as free association, in which the client expresses thoughts exactly as they occur, even though they may seem irrelevant. This procedure is designed to reveal areas of conflict and to bring into consciousness traumatic events that have been repressed, the theory being that earlier thoughts and associations can be derived from current thoughts with similar patterns of association.



attention deficit hyperactivity disorder

attention deficit hyperactivity disorder (ADHD), formerly called hyperkinesis or minimal brain dysfunction, a chronic, neurologically based syndrome characterized by any or all of three types of behavior: hyperactivity, distractibility, and impulsivity. Hyperactivity refers to feelings of restlessness, fidgeting, or inappropriate activity (running, wandering) when one is expected to be quiet; distractibility to heightened distraction by irrelevant sights and sounds or carelessness and inability to carry simple tasks to completion; and impulsivity to socially inappropriate speech (e.g., blurting out something without thinking) or striking out. Unlike similar behaviors caused by emotional problems or anxiety, ADHD does not fluctuate with emotional states. While the three typical behaviors occur in nearly everyone from time to time, in those with ADHD they are excessive, long-term, and pervasive and create difficulties in school, at home, or at work. ADHD is usually diagnosed before age seven. It is often accompanied by a learning disability.

The cause of ADHD is unknown, although there appears to be a genetic component in some cases. Intake of sugars, preservatives, and artificial flavorings is no longer considered to be a factor. It has been shown that people with ADHD have less activity in areas of the brain that control attention. Treatment usually includes behavioral therapy and emotional counseling combined with medications such as methylphenidate hydrochloride (Ritalin) or dextroamphetamine (Dexedrine) that correct neurochemical imbalances in the brain. Symptoms may decrease after adolescence, although they often persist into adulthood.




behaviorism

behaviorism, school of psychology which seeks to explain animal and human behavior entirely in terms of observable and measurable responses to environmental stimuli. Behaviorism was introduced (1913) by the American psychologist John B. Watson, who insisted that behavior is a physiological reaction to environmental stimuli. He rejected the exploration of mental processes as unscientific. The conditioned-reflex experiments of the Russian physiologist Ivan Pavlov and the American psychologist Edward Thorndike were central to the development of behaviorism. The American behaviorist B. F. Skinner contended that all but a few emotions were conditioned by habit, and could be learned or unlearned. The therapeutic system of behavior modification has emerged from behaviorist theory. Therapy intends to shape behavior through a variety of processes known as conditioning. Popular techniques include systematic desensitization, generally used on clients suffering from anxiety or fear of an object or situation, and aversive conditioning, employed in cases where a client wishes to be broken of an unhealthy habit (such as smoking or drug abuse). Other behavior therapies include systems of rewards or punishments, and modeling, in which the client views situations in which healthy behaviors are shown to lead to rewards.



Bedlam

Bethlem Royal Hospital is the oldest institution for the care and confinement of the mentally ill in England, and one of the oldest in Europe. A priory in 1247, the building was converted to its later usage c.1400. The hospital moved in 1675, in 1815, and to its present location near Croydon in 1930. The word bedlam, which is derived from the hospital's name, has long been applied to any place or scene of wild turmoil and confusion. Presently, Bethlem Royal Hospital is connected with the Univ. of London's Institute of Psychiatry, and is part of the Maudsley Hospital.



bipolar disorder

bipolar disorder, formerly manic-depressive disorderor manic-depression,severe mental disorder involving manic episodes that are usually accompanied by episodes of depression. The term “manic-depression” was introduced by the German psychiatrist Emil Kraepelin in 1896. The manic phase of the disorder is characterized by an abnormally elevated or irritable mood, grandiosity, sleeplessness, extravagance, and a tendency toward irrational judgment. During the depressed phase, the person tends to appear lethargic and withdrawn, shows a lack of concentration, and expresses feelings of worthlessness, self-blame, and guilt. This dual character of the disorder has given it the name bipolar disorder, in contrast to the unipolar depression symptomatic of the majority of mood disorders. The symptoms range in intensity and pattern and may not be recognized at first. Individuals suffering from bipolar disorder may have long periods in their lives without episodes of mania or depression, but manic-depressives have the highest suicide rate of any group with a psychological disorder.



catalepsy

The pathological condition characterized by a loss of consciousness accompanied by rigidity of muscles that keeps limbs in any position in which they are placed. Attacks vary from several minutes to days and occur in a variety of clinical syndromes, most frequently in schizophrenia, epilepsy, and hysteria.



catatonia

The mental state generally characterized by statuesque posturing, muscular immobility, mutism, and apparent stupor. The muscles are held in a pliant state called waxy flexibility, and the catatonic person obediently permits himself to be rearranged into awkward positions that he may subsequently hold for hours. Another form of catatonia involves continuous incoherent shouting, psychomotor agitation, and a violent destructiveness which can lead to collapse and death if untreated. Loss of memory or intellect is not necessarily implied: catatonic patients often display excellent memory of their surroundings during the catatonic state. In recent years, drug therapy has been helpful in the avoidance of catatonic disturbances, and the appearance of catatonia is now quite rare. Described by Karl Kahlbaum (1874) as catatonia, the term was subsumed under Eugen Bleuler's concept of schizophrenia in 1911. It has recently been classified as catatonic schizophrenia by the American Psychiatric Association.



cognitive psychology

cognitive psychology, school of psychology that examines internal mental processes such as problem solving, memory, and language. It had its foundations in the Gestalt psychology of Max Wertheimer, Wolfgang Köhler, and Kurt Koffka, and in the work of Jean Piaget, who studied intellectual development in children. Cognitive psychologists are interested in how people understand, diagnose, and solve problems, concerning themselves with the mental processes which mediate between stimulus and response. Cognitive theory contends that solutions to problems take the form of algorithms—rules that are not necessarily understood but promise a solution, or heuristics—rules that are understood but that do not always guarantee solutions. In other instances, solutions may be found through insight, a sudden awareness of relationships. Cognitive psychologists have tried to reach a greater understanding of human memory (see memory) and language. In recent years, cognitive psychology has become associated with information processing, which examines artificial intelligence in computers to find out whether they are capable of problem solving in ways similar to humans. Information processing theory studies the parallels between the human brain and the computer, in the ways that both can receive, process, store, and retrieve information.



consciousness

consciousness, in psychology, a term commonly used to indicate a state of awareness of self and environment. In Freudian psychology, conscious behavior largely includes cognitive processes of the ego, such as thinking, perception, and planning, as well as some aspects of the superego, such as moral conscience. Some psychologists deny the distinction between conscious and unconscious behavior; others use the term consciousness to indicate all the activities of an individual that constitute the personality. In recent years, neuropsychologists have begun to investigate the links between consciousness and memory, as well as altered states of consciousness such as the dream state.



defense mechanism

defense mechanism, in psychoanalysis, any of a variety of unconscious personality reactions which the ego uses to protect the conscious mind from threatening feelings and perceptions. Sigmund Freud first used defense as a psychoanalytic term (1894), but he did not break the notion into categories, viewing it as a singular phenomenon of repression. His daughter, Anna Freud, expanded on his theories in the 1930s, distinguishing some of the major defense mechanisms recognized today. Primary defense mechanisms include repression and denial, which serve to prevent unacceptable ideas or impulses from entering the conscience. Secondary defense mechanisms—generally appearing as an outgrowth of the primary defense mechanisms—include projection, reaction formation, displacement, sublimation, and isolation.




delusion

delusion, false belief based upon a misinterpretation of reality. It is not, like a hallucination, a false sensory perception, or like an illusion, a distorted perception. Delusions vary in intensity, and are not uncommon among substance abusers, particularly those who use amphetamines, cocaine, and hallucinogens. They also occur frequently among individuals who have been diagnosed with Alzheimer's disease, Huntington's disease, or schizophrenia, and during the manic stage of bipolar disorder (see depression). Some common delusions include persecutory delusions, in which the individual falsely believes that others are plotting against him; delusions of thought broadcasting, where the individual believes his thoughts can be transmitted to others; delusions of thought insertion, in which the individual believes that thoughts are being implanted in his mind; and delusions of grandeur, in which the individual imagines himself an unappreciated person of great importance.



dementia

It is progressive deterioration of intellectual faculties resulting in apathy, confusion, and stupor. In the 17th cent. the term was synonymous with insanity, and the term dementia praecox was used in the 19th cent. to describe the condition now known as schizophrenia. In recent years, the term has generally been used to describe various conditions of mental deterioration occurring in middle to later life. Dementia, in its contemporary usage, is an irreversible condition, and is not applied to states of mental deterioration that may be overcome, such as delirium. The condition is generally caused by deterioration of brain tissue, though it can occassionally be traced to deterioration of the circulatory system. Major characteristics include short- and long-term memory loss, impaired judgement, slovenly appearance, and poor hygiene. Dementia disrupts personal relationships and the ability to function occupationally. Senility (senile dementia) in old age is the most commonly recognized form of dementia, usually occurring after the age of 65. Alzheimer's disease can begin at a younger age, and deterioration of the brain tissue tends to happen much more quickly. Individuals who have experienced cerebrovascular disease (particularly strokes) may develop similar brain tissue deterioration, with symptoms similar to Alzheimer's disease and senile dementia. Other types of dementia include Huntington's disease, Parkinson's disease, and Pick's disease. Some forms of familial Alzheimer's disease are caused by specific dominant gene mutations.



denial

denial, in psychology, an ego defense mechanism that operates unconsciously to resolve emotional conflict, and to allay anxiety by refusing to perceive the more unpleasant aspects of external reality. In the psychoanalytic theory of Sigmund Freud, denial is described as a primitive defense mechanism. Anna Freud studied the widespread occurrence of denial among small children and explained that the mature ego does not continue to make extensive use of denial, because it conflicts with the capacity to recognize and critically test reality. Most people employ denial at some time in their lives when coping with stressful situations, such as the death of a loved one. Elisabeth Kübler-Ross's influential theory describes denial as the first stage of a dying person's progress in coming to terms with terminal illness. In such instances, denial may be considered adaptive. It is considered maladaptive, however, when it becomes delusional. In recent years, the term is used more generally, to describe the suppression of reality rather than a particular defense mechanism in the Freudian sense.




depression

depression, in psychiatry, a symptom of mood disorder characterized by intense feelings of loss, sadness, hopelessness, failure, and rejection. The two major types of mood disorder are unipolar disorder, also called major depression, and bipolar disorder, whose sufferers are termed manic-depressive. Other types of depression are recognized, with characteristics similar to the major mood disorders, but not as severe: they are adjustment disorder with depression, dysthymic disorder, and cyclothymic disorder.

Close to 20% of Americans are likely to suffer major depression at some time, and women tend to be more susceptible to the disorder than men. Major depression is likely to interfere significantly with everyday activity, with symptoms including insomnia, irritability, weight loss, and a lack of interest in outside events. The disorder may last several months or longer—and may recur—but it is generally reversible in the short run.

Bipolar disorder is much rarer, affecting only about 1% of the U.S. population; women and men tend to be equally susceptible. Its sufferers alternate between states of depression—similar to that which is experienced in unipolar disorder—and mania, which is characterized by intense euphoria and frenetic activity. Bipolar disorders are often interspersed with periods of relatively normal behavior, which may last for long periods of time between episodes of depression or mania. Manic-depressives have an extremely high rate of suicide, and episodes of the disorder tend to recur.

Medical evidence suggests that depressive states may be connected to deficiencies in the neurotransmitters norepinephrine and serotonin. Drug therapy includes various antidepressants that act on the flow of neurotransmitters and lithium for bipolar disorder (antidepressants can cause mania when used to treat depression in bipolar patients). There also has been success with electroconvulsive therapy (ECT) for major depression.

In recent years, theorists have argued that many depressed individuals depend upon others for their self-esteem, and that the loss of one of these emotional supports often precipitates a depressive reaction. A number of psychologists contend instead that depression is a result of learned helplessness, which occurs when a person determines through experience that his actions are useless in making positive changes. Other theorists have shown that genetic factors play a major role in depression.



dream

dream, mental activity associated with the rapid-eye-movement (REM) period of sleep. It is commonly made up of a number of visual images, scenes or thoughts expressed in terms of seeing rather than in those of the other senses or in words. Electroencephalograph studies, measuring the electrical activity of the brain during REM sleep, have shown that young adults dream for 1 1/2 to 2 hours of every 8-hour period of sleep. Infants spend an average of 50% of their sleep in the REM phase (they are believed to dream more often than adults) a figure which decreases steadily with age. During dreams, blood pressure and heart rate increase, and breathing is quickened, but the body is otherwise immobile. Studies have shown that sleepers deprived of dream-sleep are likely to become irritable and lose coordination skills. Unusually frightening dreams are called nightmares, and daydreams are constructed fantasies that occur while the individual is awake. Studies have demonstrated the existence of lucid dreaming, where the individual is aware that he is dreaming and has a degree of control over his dream.

Sigmund Freud, in his pioneering work The Interpretation of Dreams (1900, tr. 1913), was one of the first to emphasize dreams as keys to the unconscious. He distinguished the manifest content of dreams—the dream as it is recalled by the individual—from the latent content or the meaning of the dream, which Freud saw in terms of wish fulfillment. C. G. Jung held that dreams function to reveal the unconscious mind, anticipate future events, and give expression to neglected areas of the dreamer's personality. Another theory, which PET scan studies appear to support, suggests that dreams are a result of electrical energy that stimulates memories located in various regions of the brain.

Using children in his studies, Bandura demonstrated that, by watching another person act aggressively and obtain desirable rewards or by learning through personal experience that such behavior yields rewards, aggression can be learned. Leonard Berkowitz has contended that all animals learn the most effective response to an aversive occurence (one where the expected reward is denied), whether it be attack or flight. A number of psychologists contend that children and adolescents are vulnerable to media portrayals of violence, particularly in film and television. Popular media tends to depict violence as relatively common, and generally effective. Anonymity may facilitate aggression: when an individual is part of a large group, he may be more likely to elicit aggressive behavior, in a process known as deindividuation.

Recent research on the biological basis of aggression has sought to show that genetic factors may be responsible for aggressive behavior. In the 1970s it was suggested that men who were born with an extra Y chromosome were likely to display more episodes of aggressive behavior than men who were not born with this extra chromosome. Still, conclusive proof has yet to be found for a genetic theory of aggression.

Other factors, including learning difficulties, minimal brain damage, brain abnormalities—such as temporal lobe epilepsy—and such social factors as crowding and poverty have been suggested to have contributed in certain cases to exaggeratedly aggressive behavior. Psychological investigation into aggressive behavior continues, with significant corrolary studies being performed in endocrinology—to determine whether hormonal imbalances have an impact on behavior—and in primate research. Each theory may be accurate in part, since aggression is believed to have a number of determining factors.




ambivalence

It is coexistence of two opposing drives, desires, feelings, or emotions toward the same person, object, or goal. The ambivalent person may be unaware of either of the opposing wishes. The term was coined in 1911 by Eugen Bleuler, to designate one of the major symptoms of schizophrenia, the others being autism and disturbances of affect (i.e., emotion) and of association (i.e., thought disorders). Bleuler felt that there were normal instances of ambivalence, such as the feeling, after performing an action, that it would have been better to have done the opposite; but the normal person, unlike the schizophrenic, is not prevented by these opposing impulses from deciding and acting. In Freudian psychoanalysis, ambivalence was described as feelings of love and hate toward the same person. This specific meaning has attained common usage by psychiatrists and psychoanalysts.




amnesia

It is the condition characterized by loss of memory for long or short intervals of time. It may be caused by injury, shock, senility, severe illness, or mental disease. Some cases of amnesia involve the unconscious suppression of a painful experience and everything remindful of it including the individual's identity (see defense mechanism). Retrograde amnesia is loss of memory of events just preceding temporary loss of consciousness, as from head injury; it is evidence that memory proceeds in two stages, short term and long term. One form of the condition known as tropic amnesia, or coast memory, affecting white men in the tropics, is probably a variety of hysteria. Aphasia of the amnesic variety is caused by an organic brain condition and is not to be confused with other forms of amnesia. To cure amnesia, attempts are made to establish associations with the past by suggestion, and hypnotism is sometimes employed.



anxiety

anxiety, anticipatory tension or vague dread persisting in the absence of a specific threat. In contrast to fear, which is a realistic reaction to actual danger, anxiety is generally related to an unconscious threat. Physiological symptoms of anxiety include increases in pulse rate and blood pressure, accelerated breathing rates, perspiration, muscular tension, dryness of the mouth, and diarrhea. Freud postulated that anxiety was a result of repressed, pent-up sexual energy, but later came to view it as a danger signal alerting the ego to excessive stimulation and causing repression. Anxiety disorders include observable, overt anxiety, as well as phobias and other conditions where a defense mechanism has been set up to disguise the anxiety from both the sufferer and the observer. In generalized anxiety, the individual experiences long-term anxiety with no explanation for its cause; such a condition may be called free-floating, since it is not linked to a specific stimulus. Panic disorder involves sudden anxiety attacks which are manifested in heart palpitations, shortness of breath, or fainting. The individual with a phobic disorder can identify the stimulus that causes anxiety: such stimuli as enclosed space, heights, and crowds become imbued with greatly exaggerated anxiety and are carefully avoided by the phobic individual. Obsessive-compulsive disorders (OCD) are characterized by obsessions (mental quandries) and compulsions (physical actions) that engage the individual excessively. Extreme anxiety may be experienced if the person does not carry out the compulsion or attempts to ignore the obsession. Post-traumatic stress disorder occurs when an individual has recurrent dreams, flashbacks, or panic attacks after a particularly traumatic experience.




aphasia

language disturbance caused by a lesion of the brain, making an individual partially or totally impaired in his ability to speak, write, or comprehend the meaning of spoken or written words. It is distinguished from functional disorders such as stammering or stuttering, and from impaired speech due to physical defects in the organs used for speaking. Treatment consists of reeducation; the oral and lip-reading methods employed in the education of deaf and mute children have been found to be of assistance in therapy.



association

association, in psychology, a connection between different sensations, feelings, or ideas by virtue of their previous occurrence together in experience. The concept of association entered contemporary psychology through the empiricist philosophers John Locke, George Berkeley, David Hume, and David Hartley, and the British associationist school of James Mill, John Stuart Mill, and others (see associationism). Translated into the stimulus-response terms of behaviorism, association has been thought of as the basis of learning and conditioning. Paired experience and the principle of reinforcement are often invoked to explain associative learning. However, Gestalt psychologists, who believe that association between items is dependent on their relations to each other, interpret association as an aftereffect of perceptual organization. Psychoanalysis uses a technique known as free association, in which the client expresses thoughts exactly as they occur, even though they may seem irrelevant. This procedure is designed to reveal areas of conflict and to bring into consciousness traumatic events that have been repressed, the theory being that earlier thoughts and associations can be derived from current thoughts with similar patterns of association.



attention deficit hyperactivity disorder

attention deficit hyperactivity disorder (ADHD), formerly called hyperkinesis or minimal brain dysfunction, a chronic, neurologically based syndrome characterized by any or all of three types of behavior: hyperactivity, distractibility, and impulsivity. Hyperactivity refers to feelings of restlessness, fidgeting, or inappropriate activity (running, wandering) when one is expected to be quiet; distractibility to heightened distraction by irrelevant sights and sounds or carelessness and inability to carry simple tasks to completion; and impulsivity to socially inappropriate speech (e.g., blurting out something without thinking) or striking out. Unlike similar behaviors caused by emotional problems or anxiety, ADHD does not fluctuate with emotional states. While the three typical behaviors occur in nearly everyone from time to time, in those with ADHD they are excessive, long-term, and pervasive and create difficulties in school, at home, or at work. ADHD is usually diagnosed before age seven. It is often accompanied by a learning disability.

The cause of ADHD is unknown, although there appears to be a genetic component in some cases. Intake of sugars, preservatives, and artificial flavorings is no longer considered to be a factor. It has been shown that people with ADHD have less activity in areas of the brain that control attention. Treatment usually includes behavioral therapy and emotional counseling combined with medications such as methylphenidate hydrochloride (Ritalin) or dextroamphetamine (Dexedrine) that correct neurochemical imbalances in the brain. Symptoms may decrease after adolescence, although they often persist into adulthood.




behaviorism

behaviorism, school of psychology which seeks to explain animal and human behavior entirely in terms of observable and measurable responses to environmental stimuli. Behaviorism was introduced (1913) by the American psychologist John B. Watson, who insisted that behavior is a physiological reaction to environmental stimuli. He rejected the exploration of mental processes as unscientific. The conditioned-reflex experiments of the Russian physiologist Ivan Pavlov and the American psychologist Edward Thorndike were central to the development of behaviorism. The American behaviorist B. F. Skinner contended that all but a few emotions were conditioned by habit, and could be learned or unlearned. The therapeutic system of behavior modification has emerged from behaviorist theory. Therapy intends to shape behavior through a variety of processes known as conditioning. Popular techniques include systematic desensitization, generally used on clients suffering from anxiety or fear of an object or situation, and aversive conditioning, employed in cases where a client wishes to be broken of an unhealthy habit (such as smoking or drug abuse). Other behavior therapies include systems of rewards or punishments, and modeling, in which the client views situations in which healthy behaviors are shown to lead to rewards.



Bedlam

Bethlem Royal Hospital is the oldest institution for the care and confinement of the mentally ill in England, and one of the oldest in Europe. A priory in 1247, the building was converted to its later usage c.1400. The hospital moved in 1675, in 1815, and to its present location near Croydon in 1930. The word bedlam, which is derived from the hospital's name, has long been applied to any place or scene of wild turmoil and confusion. Presently, Bethlem Royal Hospital is connected with the Univ. of London's Institute of Psychiatry, and is part of the Maudsley Hospital.



bipolar disorder

bipolar disorder, formerly manic-depressive disorderor manic-depression,severe mental disorder involving manic episodes that are usually accompanied by episodes of depression. The term “manic-depression” was introduced by the German psychiatrist Emil Kraepelin in 1896. The manic phase of the disorder is characterized by an abnormally elevated or irritable mood, grandiosity, sleeplessness, extravagance, and a tendency toward irrational judgment. During the depressed phase, the person tends to appear lethargic and withdrawn, shows a lack of concentration, and expresses feelings of worthlessness, self-blame, and guilt. This dual character of the disorder has given it the name bipolar disorder, in contrast to the unipolar depression symptomatic of the majority of mood disorders. The symptoms range in intensity and pattern and may not be recognized at first. Individuals suffering from bipolar disorder may have long periods in their lives without episodes of mania or depression, but manic-depressives have the highest suicide rate of any group with a psychological disorder.



catalepsy

The pathological condition characterized by a loss of consciousness accompanied by rigidity of muscles that keeps limbs in any position in which they are placed. Attacks vary from several minutes to days and occur in a variety of clinical syndromes, most frequently in schizophrenia, epilepsy, and hysteria.



catatonia

The mental state generally characterized by statuesque posturing, muscular immobility, mutism, and apparent stupor. The muscles are held in a pliant state called waxy flexibility, and the catatonic person obediently permits himself to be rearranged into awkward positions that he may subsequently hold for hours. Another form of catatonia involves continuous incoherent shouting, psychomotor agitation, and a violent destructiveness which can lead to collapse and death if untreated. Loss of memory or intellect is not necessarily implied: catatonic patients often display excellent memory of their surroundings during the catatonic state. In recent years, drug therapy has been helpful in the avoidance of catatonic disturbances, and the appearance of catatonia is now quite rare. Described by Karl Kahlbaum (1874) as catatonia, the term was subsumed under Eugen Bleuler's concept of schizophrenia in 1911. It has recently been classified as catatonic schizophrenia by the American Psychiatric Association.



cognitive psychology

cognitive psychology, school of psychology that examines internal mental processes such as problem solving, memory, and language. It had its foundations in the Gestalt psychology of Max Wertheimer, Wolfgang Köhler, and Kurt Koffka, and in the work of Jean Piaget, who studied intellectual development in children. Cognitive psychologists are interested in how people understand, diagnose, and solve problems, concerning themselves with the mental processes which mediate between stimulus and response. Cognitive theory contends that solutions to problems take the form of algorithms—rules that are not necessarily understood but promise a solution, or heuristics—rules that are understood but that do not always guarantee solutions. In other instances, solutions may be found through insight, a sudden awareness of relationships. Cognitive psychologists have tried to reach a greater understanding of human memory (see memory) and language. In recent years, cognitive psychology has become associated with information processing, which examines artificial intelligence in computers to find out whether they are capable of problem solving in ways similar to humans. Information processing theory studies the parallels between the human brain and the computer, in the ways that both can receive, process, store, and retrieve information.



consciousness

consciousness, in psychology, a term commonly used to indicate a state of awareness of self and environment. In Freudian psychology, conscious behavior largely includes cognitive processes of the ego, such as thinking, perception, and planning, as well as some aspects of the superego, such as moral conscience. Some psychologists deny the distinction between conscious and unconscious behavior; others use the term consciousness to indicate all the activities of an individual that constitute the personality. In recent years, neuropsychologists have begun to investigate the links between consciousness and memory, as well as altered states of consciousness such as the dream state.



defense mechanism

defense mechanism, in psychoanalysis, any of a variety of unconscious personality reactions which the ego uses to protect the conscious mind from threatening feelings and perceptions. Sigmund Freud first used defense as a psychoanalytic term (1894), but he did not break the notion into categories, viewing it as a singular phenomenon of repression. His daughter, Anna Freud, expanded on his theories in the 1930s, distinguishing some of the major defense mechanisms recognized today. Primary defense mechanisms include repression and denial, which serve to prevent unacceptable ideas or impulses from entering the conscience. Secondary defense mechanisms—generally appearing as an outgrowth of the primary defense mechanisms—include projection, reaction formation, displacement, sublimation, and isolation.




delusion

delusion, false belief based upon a misinterpretation of reality. It is not, like a hallucination, a false sensory perception, or like an illusion, a distorted perception. Delusions vary in intensity, and are not uncommon among substance abusers, particularly those who use amphetamines, cocaine, and hallucinogens. They also occur frequently among individuals who have been diagnosed with Alzheimer's disease, Huntington's disease, or schizophrenia, and during the manic stage of bipolar disorder (see depression). Some common delusions include persecutory delusions, in which the individual falsely believes that others are plotting against him; delusions of thought broadcasting, where the individual believes his thoughts can be transmitted to others; delusions of thought insertion, in which the individual believes that thoughts are being implanted in his mind; and delusions of grandeur, in which the individual imagines himself an unappreciated person of great importance.



dementia

It is progressive deterioration of intellectual faculties resulting in apathy, confusion, and stupor. In the 17th cent. the term was synonymous with insanity, and the term dementia praecox was used in the 19th cent. to describe the condition now known as schizophrenia. In recent years, the term has generally been used to describe various conditions of mental deterioration occurring in middle to later life. Dementia, in its contemporary usage, is an irreversible condition, and is not applied to states of mental deterioration that may be overcome, such as delirium. The condition is generally caused by deterioration of brain tissue, though it can occassionally be traced to deterioration of the circulatory system. Major characteristics include short- and long-term memory loss, impaired judgement, slovenly appearance, and poor hygiene. Dementia disrupts personal relationships and the ability to function occupationally. Senility (senile dementia) in old age is the most commonly recognized form of dementia, usually occurring after the age of 65. Alzheimer's disease can begin at a younger age, and deterioration of the brain tissue tends to happen much more quickly. Individuals who have experienced cerebrovascular disease (particularly strokes) may develop similar brain tissue deterioration, with symptoms similar to Alzheimer's disease and senile dementia. Other types of dementia include Huntington's disease, Parkinson's disease, and Pick's disease. Some forms of familial Alzheimer's disease are caused by specific dominant gene mutations.



denial

denial, in psychology, an ego defense mechanism that operates unconsciously to resolve emotional conflict, and to allay anxiety by refusing to perceive the more unpleasant aspects of external reality. In the psychoanalytic theory of Sigmund Freud, denial is described as a primitive defense mechanism. Anna Freud studied the widespread occurrence of denial among small children and explained that the mature ego does not continue to make extensive use of denial, because it conflicts with the capacity to recognize and critically test reality. Most people employ denial at some time in their lives when coping with stressful situations, such as the death of a loved one. Elisabeth Kübler-Ross's influential theory describes denial as the first stage of a dying person's progress in coming to terms with terminal illness. In such instances, denial may be considered adaptive. It is considered maladaptive, however, when it becomes delusional. In recent years, the term is used more generally, to describe the suppression of reality rather than a particular defense mechanism in the Freudian sense.




depression

depression, in psychiatry, a symptom of mood disorder characterized by intense feelings of loss, sadness, hopelessness, failure, and rejection. The two major types of mood disorder are unipolar disorder, also called major depression, and bipolar disorder, whose sufferers are termed manic-depressive. Other types of depression are recognized, with characteristics similar to the major mood disorders, but not as severe: they are adjustment disorder with depression, dysthymic disorder, and cyclothymic disorder.

Close to 20% of Americans are likely to suffer major depression at some time, and women tend to be more susceptible to the disorder than men. Major depression is likely to interfere significantly with everyday activity, with symptoms including insomnia, irritability, weight loss, and a lack of interest in outside events. The disorder may last several months or longer—and may recur—but it is generally reversible in the short run.

Bipolar disorder is much rarer, affecting only about 1% of the U.S. population; women and men tend to be equally susceptible. Its sufferers alternate between states of depression—similar to that which is experienced in unipolar disorder—and mania, which is characterized by intense euphoria and frenetic activity. Bipolar disorders are often interspersed with periods of relatively normal behavior, which may last for long periods of time between episodes of depression or mania. Manic-depressives have an extremely high rate of suicide, and episodes of the disorder tend to recur.

Medical evidence suggests that depressive states may be connected to deficiencies in the neurotransmitters norepinephrine and serotonin. Drug therapy includes various antidepressants that act on the flow of neurotransmitters and lithium for bipolar disorder (antidepressants can cause mania when used to treat depression in bipolar patients). There also has been success with electroconvulsive therapy (ECT) for major depression.

In recent years, theorists have argued that many depressed individuals depend upon others for their self-esteem, and that the loss of one of these emotional supports often precipitates a depressive reaction. A number of psychologists contend instead that depression is a result of learned helplessness, which occurs when a person determines through experience that his actions are useless in making positive changes. Other theorists have shown that genetic factors play a major role in depression.



dream

dream, mental activity associated with the rapid-eye-movement (REM) period of sleep. It is commonly made up of a number of visual images, scenes or thoughts expressed in terms of seeing rather than in those of the other senses or in words. Electroencephalograph studies, measuring the electrical activity of the brain during REM sleep, have shown that young adults dream for 1 1/2 to 2 hours of every 8-hour period of sleep. Infants spend an average of 50% of their sleep in the REM phase (they are believed to dream more often than adults) a figure which decreases steadily with age. During dreams, blood pressure and heart rate increase, and breathing is quickened, but the body is otherwise immobile. Studies have shown that sleepers deprived of dream-sleep are likely to become irritable and lose coordination skills. Unusually frightening dreams are called nightmares, and daydreams are constructed fantasies that occur while the individual is awake. Studies have demonstrated the existence of lucid dreaming, where the individual is aware that he is dreaming and has a degree of control over his dream.

Sigmund Freud, in his pioneering work The Interpretation of Dreams (1900, tr. 1913), was one of the first to emphasize dreams as keys to the unconscious. He distinguished the manifest content of dreams—the dream as it is recalled by the individual—from the latent content or the meaning of the dream, which Freud saw in terms of wish fulfillment. C. G. Jung held that dreams function to reveal the unconscious mind, anticipate future events, and give expression to neglected areas of the dreamer's personality. Another theory, which PET scan studies appear to support, suggests that dreams are a result of electrical energy that stimulates memories located in various regions of the brain.









to be continued....
emotion

emotion, term commonly and loosely used to denote individual, subjective feelings which dictate moods. In psychology, emotion is considered a response to stimuli that involves characteristic physiological changes—such as increase in pulse rate, rise in body temperature, greater or less activity of certain glands, change in rate of breathing—and tends in itself to motivate the individual toward further activity. Early psychological studies of emotion tried to determine whether a certain emotion arose before the action, simultaneously with it, or as a response to automatic physiological processes. In the 1960s, the Schachter-Singer theory pointed out that cognitive processes, not just physiological reactions, played a significant role in determining emotions. Robert Plutchik developed (1980) a theory showing eight primary human emotions: joy, acceptance, fear, submission, sadness, disgust, anger, and anticipation, and argued that all human emotions can be derived from these. Psychologists Sylvan Tomkins (1963) and Paul Ekman (1982) have contended that “basic” emotions can be quantified because all humans employ the same facial muscles when expressing a particular emotion. Studies done by Ekman suggest that muscular feedback from a facial expression characteristic of a certain emotion results in the experience of that emotion. Since emotions are abstract and subjective, however, they remain difficult to quantify: some theories point out that non-Western cultural groups experience emotions quite distinct from those generally seen as “basic” in the West.



extroversion and introversion

extroversion and introversion, terms introduced into psychology by Carl Jung to identify opposite psychological types. Jung saw the activity of the extrovert directed toward the external world and that of the introvert inward upon himself or herself. This general activity or drive of the individual was called the libido by Jung, who removed from the term the sexual character ascribed to it by Sigmund Freud. The extrovert is characteristically the active person who is most content when surrounded by people; carried to the neurotic extreme such behavior appears to constitute an irrational flight into society, where the extrovert's feelings are acted out. The introvert, on the other hand, is normally a contemplative individual who enjoys solitude and the inner life of ideas and the imagination. The extreme introvert's fantasies give him or her libidinal satisfactions and tend to become more meaningful to him than objective reality. Severe introversion is characteristic of autism and some forms of schizophrenia. Jung did not suggest strict classification of individuals as extroverted or introverted, since each person has tendencies in both directions, although one direction generally predominates. Influenced by Jung, Hans Eysenck conducted research on large samples of individuals, creating more objective classifications for extroversion and introversion.



electroconvulsive therapy

electroconvulsive therapy in psychiatry, treatment of mood disorders by means of electricity; the broader term “shock therapy” also includes the use of chemical agents. The therapeutic possibilities of these treatments were discovered in the 1930s by Manfred Sakel, a Polish psychiatrist, using insulin; L. J. Meduna, an American psychiatrist, using Metrazol; and Ugo Cerletti and Lucio Bini, Italian psychiatrists, using electric shock. Metrazol and insulin accounted for a very limited number of remissions in cases of schizophrenia. However, the injection of insulin often caused coma, while Metrazol and electric shock resulted in convulsions similar to those of epileptics.

Advances in electroconvulsive therapy (ECT) have made it the standard mechanism of shock therapy. ECT has had unquestionable success with involutional melancholia and other depressive disorders, although it may be ineffective or only temporarily effective. ECT is generally employed only after other therapies for depression, mania, bipolar disorder or schizophrenia have proven ineffective. The administration of anesthetics and muscle relaxants prior to ECT has greatly reduced the risk of injury during the procedure, which is typically administered six to eight times over a period of several weeks. The seizure lasts for up to 20 seconds, and the patient can be up and about in about an hour. Long-term memory loss is the main significant potential side effect; headache and temporary short-term memory loss may occur. Why ECT works, however, is still not fully understood, but it may be the result of neurotransmitters released in the brain as a result of the seizure.



fetishism

fetishism, in psychiatry, a paraphilia in which erotic interest and satisfaction are centered on an inanimate object or a specific, nongenital part of the anatomy. Generally occurring in males, fetishism frequently centers on a garment (e.g., underclothing or high-heeled shoes) or such parts of the body as the foot. In some cases, fetishism becomes severe enough to inspire the fetishist to acquire objects of his desire through theft or assault. In psychoanalysis, a fetish is believed to represent a substitute for male genitalia, which women are imagined to have lost through castration. Although the causes of fetishism are not clearly known, it is generally not considered a serious disorder, unless it is coupled with other psychological disturbances.



Gestalt

It is the school of psychology that interprets phenomena as organized wholes rather than as aggregates of distinct parts, maintaining that the whole is greater than the sum of its parts. The term Gestalt was coined by the philosopher Christian von Ehrenfels in 1890, to denote experiences that require more than the basic sensory capacities to comprehend. In 1912, the movement was given impetus in psychology by German theorists Max Wertheimer, Wolfgang Köhler, and Kurt Koffka as a protest against the prevailing atomistic, analytical psychological thought. It was also a departure from the general intellectual climate, which emphasized a scientific approach characterized by a detachment from basic human concerns. According to the school, understanding of psychological phenomena such as perceptual illusions could not be derived by merely isolating the elementary parts for analysis, because human perception may organize sensory stimuli in any number of ways, making the whole different from the sum of the parts. Gestalt psychologists suggest that the events in the brain bear a structural correspondence to psychological events; indeed, it has been shown that steady electric currents in the brain correspond to structured perceptual events. The Gestalt school has made substantial contributions to the study of learning, recall, and the nature of associations, as well as important contributions to personality and social psychology. Gestalt therapy, developed after World War II by Frederick Perls, believes that a person's inability to successfully integrate the parts of his personality into a healthy whole may lie at the root of psychological disturbance. In therapy, the analyst encourages clients to release their emotions, and to recognize these emotions for what they are. Gestalt psychology has been thought of as analogous to field physics.



group psychotherapy

group psychotherapy, a means of changing behavior and emotional patterns, based on the premise that much of human behavior and feeling involves the individual's adaptation and response to other people. It is a process carried out in formally organized groups of three or more individuals who seek change, whether their problem is alcoholism, overeating, or poor social skills. The composition of a group may be heterogenous or homogeneous with reference to the age of the members or the type of problem. The therapist may be directive or nondirective, allowing the group to set their own agenda for discussion. The group becomes a “sample” of the outside world, reproducing conditions of interpersonal relationships; its members jointly participate in observing personal motivation and styles of interaction. They also participate in attempting new behaviors and dealing with the consequences of such behaviors, with the intended result that they will eventually be able to employ these behavior patterns outside the group. In observing the totality of the events that take place in group therapy, the process by which elements of personality are developed in each member is also studied.


Origins of Group Therapy


The technique of formally organized group therapy is said to have been devised by J. H. Pratt in 1905. Pratt was holding general-care instruction classes for recently discharged tuberculosis patients when he noticed the impact of this experience on their emotional states. In 1925 psychoanalyst Trigant Burrow became dissatisfied with individual psychoanalysis, and began experimenting with group techniques. Burrow hoped to decrease the authoritarian position of the therapist, and to more thoroughly examine interpersonal interactions. The application of group therapy methods to prison inmates and discharged mental hospital patients was pioneered by Paul Schilder and Louis Wender in the 1930s. At that time group therapy was found to be particularly useful in the treatment of children and adolescents. The development of group therapy was given impetus during World War II, as a result of the large number of soldiers requiring treatment.



Types of Group Therapy

There are various types of group therapy; approaches include behavior therapy, psychoanalytic therapy, sensitivity training, or Gestalt psychology. The composition of groups varies as well, with family therapy and marriage counseling common forms in recent years. Peer group therapy usually consists of a group of individuals who have similar problems, and can be mediated by a psychoanalyst or by the members themselves. Many people seeking help prefer this sort of group therapy over individual therapy, largely because of the comfort derived from knowing that others share their problems. The approach is nondirective, and in some cases, the individual can continue attending sessions whenever they are needed. Alcoholics Anonymous (AA) is a well-known peer support group, run entirely by members. AA has been influential in the formation of similar groups, particularly support groups centered on addictions.




guilt

guilt, in psychology, a term denoting an unpleasant feeling associated with unfulfilled wishes. Sigmund Freud initially contended that sexual drives produce sense of guilt in the superego, the moral conscience of the mind. He later maintained, however, that guilt was associated with aggressive impulses. Freud felt that guilt was often confused with remorse, the former being an emotion signaling the presence of aggressive wishes, the latter a self-imposed punishment which occurs if the aggressive wish is fulfilled. Individuals suffering from various neurotic disorders may experience feelings of guilt and remorse even when they have not acted on their aggressive impulses. The term guilt is most commonly used in traditional psychoanalysis, as a way of describing unconscious processes which may lead to neurotic reactions. It is also used in criminal law, in cases where a defendant is found to be responsible for the crime for which he is on trial.



hallucination

hallucination, false perception characterized by a distortion of real sensory stimuli. Common types of hallucination are auditory, i.e., hearing voices or noises and visual, i.e., seeing people that are not actually present. Hallucinations play a prominent role in schizophrenia and in the mania stage of bipolar disorder . They are also significant during withdrawal from various drugs, particularly depressants such as barbiturates, heroin, and alcohol, and under the influence of hallucinogenic drugs such as LSD, mescaline, and psylocybin. Hallucinations may occur in normal people under conditions of sensory deprivation, emotional stress, religious exaltation, or great fatigue.


hyperactivity

hyperactivity, excessive physical activity of emotional or physiological origin, usually seen in young children; one of the components of attention deficit hyperactivity disorder.



hypnotism

It may be defined to induce an altered state of consciousness characterized by deep relaxation and heightened suggestibility. The term was originally coined by James Braid in 1842 to describe a phenomenon previously known as animal magnetism or mesmerism (see Mesmer, Friedrich Anton). Superficially resembling sleep, it is generally induced by the monotonous repetition of words and gestures while the subject is completely relaxed. Although almost everyone can be hypnotized, individuals vary greatly in susceptibility. The hypnotic state is characterized by heightened suggestibility and represents an altered state of consciousness as recent research has shown electrical changes occur in brain activity when a person is hypnotized. Ernest Hilgard's neodissociation theory (1977) has been influential in the explanation of hypnosis. Hilgard's theory asserts that several distinct states of consciousness can be present during hypnosis, such that certain actions may become dissociated from the conscious mind. In the late 19th cent., it was used by a number of medical practitioners, who found that individuals susceptible to hysteria are highly suggestible and can be put into deep hypnosis, sometimes leading to a cure. Sigmund Freud used the method in psychoanalysis. In recent years, hypnosis has been widely used by practitioners as an aid in medical practice and psychotherapy. Hypnosis is also used in some criminal investigations, to help defendants to recall events they might otherwise not remember.


hypochondria

in psychology, a disorder characterized by an exaggeration of imagined or negligible physical ailment. The hypochondriac fears that such minor symptoms indicate a serious disease, and tends to be self-centered and socially withdrawn. Continually seeking professional help to reinforce his fears, the hypochondriac never feels he is receiving adequate care. Contemporary theorists have arrived at similar conclusions, suggesting that the physical ailments of hypochondriacs were a form of escape from psychological stress. The disorder is technically known as hypochondriasis, and is classified as a somatoform disorder, or one in which a psychological problem manifests itself in a physical ailment.


hysteria

in psychology, a disorder commonly known today as conversion disorder, in which a psychological conflict is converted into a bodily disturbance. It is distinguished from hypochondria by the fact that its sufferers do not generally confuse their condition with real, physical disease. Conversion disorder is usually found in patients with immature, histrionic personalities who are under great stress. Women are affected twice as frequently as men. Symptoms, which are largely symbolic and which relieve the patient's anxiety, include limb paralysis, blindness, or convulsive seizures. The specific physical disorder usually does not correspond to the anatomy; e.g., an entire limb may be paralyzed rather than a specific group of muscles. The person may also appear to be unconcerned about the illness, a condition French psychiatrist Pierre Janet called la belle indifference (1929). At the end of the 19th cent., great advances were made in the understanding and cure of hysteria by the recognition of its psychogenic nature and by the use of hypnotism to influence the hysteric patient, who is known to have a high degree of suggestibility. The Austrian physician Josef Breuer, the French psychologists J. M. Charcot and Pierre Janet, and Austrian psychiatrist Sigmund Freud were pioneers in the investigation of hysteria through hypnosis. Freud concluded that hysterical symptoms were symbolic representations of a repressed unconscious event, accompanied by strong emotions that could not be adequately expressed or discharged at the time. Instead, the strong effect associated with the event was diverted into the wrong somatic channels (conversion), and the physical symptom resulted. Psychoanalysis has had reasonable success in helping patients suffering from conversion disorder.



imprinting

imprinting, acquisition of behavior in many animal species, in which, at a critical period early in life, the animals form strong and lasting attachments. Imprinting is important for normal social development. The term was first used by the zoologist Konrad Lorenz to describe the way in which the social characteristics of greylag geese and other fowl become instilled in their young offspring. In natural circumstances imprinting, to the mother, food, or surroundings, occurs instinctively during a biologically fixed time span; it is very difficult to extinguish. Under experimental conditions chicks and ducklings readily become imprinted to an appropriate model such as a moving decoy or a human being. Subsequent learning may be tied to and reinforced by the imprinted object, and later social behaviors, such as the greeting ceremony and courtship, may be directed exclusively to the mother-substitute. In fowl, attachment increases with the amount of effort the offspring must exert to follow the imprinted object. The onset of fear in an organism is believed to end the period of imprintability. There is evidence that in fowl the imprinting period begins before hatching and is characterized by vocal communication between mother and unhatched ducklings.



instinct

instinct, term used generally to indicate an innate tendency to action, or pattern of behavior, elicited by specific stimuli and fulfilling vital needs of an organism. Examples of almost purely instinctive behavior are found in the behavior of many lower animals, in which activity (often quite complex) is performed that is not based upon past experience, e.g., reproductive and food-gathering activity in insects. Instinctive behavior generally acts as an initiator or triggering mechanism to arouse the organism, and it is modified by learned behavior as well as innate regulatory mechanisms. For example, nest-building by birds is a complex activity triggered by instinctive drives and modified by environmental conditions, such as the availability of materials and sites. Among animals, fixed patterns of instinctive behavior include fighting, courtship behavior, and escape; even these can usually be shown to be modified by experience . Freud used the term instinct when referring to human motivational forces, such as sex and aggression. Sociobiologists and ethologists such as Konrad Lorenz have sought to understand social behaviors in terms of instincts, among humans as well as other animals. The usage of the term among psychologists has largely died out; today, motivational forces among humans are generally referred to as instinctual drives.



intelligence

intelligence, in psychology, the general mental ability involved in calculating, reasoning, perceiving relationships and analogies, learning quickly, storing and retrieving information, using language fluently, classifying, generalizing, and adjusting to new situations. Alfred Binet, the French psychologist, defined intelligence as the totality of mental processes involved in adapting to the environment. Although there remains a strong tendency to view intelligence as a purely intellectual or cognitive function, considerable evidence suggests that intelligence has many facets.

Early investigations into intelligence assumed that there was one underlying general factor at its base (the g-factor), but later psychologists maintained that intelligence could not be determined by such a simplistic method. Raymond Cattell argued that intelligence can be separated into two fundamental parts: fluid ability and crystallized ability. Fluid ability is considered innate, basic reasoning skill, while crystallized intelligence is the information and skills that are acquired through experience in a cultural environment. Other psychologists have further divided intelligence into subcategories. Howard Gardner maintained (1985) that intelligence is comprised of seven components: musical, bodily-kinesthetic, logical-mathematical, linguistic, spatial, interpersonal, and intrapersonal. J. P. Guilford tried (1982) to show that there are 150 different mental abilities that constitute intelligence.

It is generally accepted that intelligence is related to both heredity and environment. Studies done on families, particularly among identical twins and adopted children, have shown that heredity is an important factor in determining intelligence; but they have also suggested that environment is a critical factor in determining the extent of its expression. For instance, children reared in orphanages or other environments that are comparatively unstimulating tend to show retarded intellectual development. In recent years, controversy regarding intelligence has centered primarily around how much of each factor, heredity and environment, is responsible for an individual's level of intelligence.



kleptomania

An irresistible compulsion to steal, motivated by neurotic impulse rather than material need. No specific cause is known. The condition is considered generally as the result of some underlying emotional disturbance rather than as a form of neurosis in itself. Legally kleptomania is not classified as insanity, and individuals are held responsible except when complete lack of control over their actions can be definitely established.


learning

learning, in psychology, the process by which a relatively lasting change in potential behavior occurs as a result of practice or experience. Learning is distinguished from behavioral changes arising from such processes as maturation and illness, but does apply to motor skills, such as driving a car, to intellectual skills, such as reading, and to attitudes and values, such as prejudice. There is evidence that neurotic symptoms and patterns of mental illness are also learned behavior. Learning occurs throughout life in animals, and learned behavior accounts for a large proportion of all behavior in the higher animals, especially in humans.



libido

psychoanalytic term used by Sigmund Freud to identify instinctive energy with the sex instinct. For Freud, libido is the generalized sexual energy of which conscious activity is the expression. C. G. Jung used the term synonymously with instinctive energy in general. Many psychiatrists now feel that Freud overemphasized the concept of libido as the determinant of personality development and did not adequately emphasize the results of socializing forces. The term drive is often used instead of libido but without the sexual implications of the latter.
