here are some theories of learning.
1.Pavlov's theory of learning...(here you have to write all about the experiment done by pavlov ...done on a dog...result he formulated after the experiments and principles of classical learning too)
2.Skinner's theory of learning(in the same manner as described above,,write about the experiment done by skinner and principles of operant conditioning.
3.Thorndike's theory of learning...you must have read the experiment of thorndike and laws presented by him.
4.Kohler's theory of insight learning..experiment on chimpanzees, and so on.
5,Hull's systematic behavior theory of learning.
In short,if the question comes in exam :you are supposed to write all the types of learning you know along with the name of psychologist who gave the idea of and any laws ,principles and other relevant material .there a are other types of learning also ..you must put them too i.e..observational learning learning by insight and etc.
write again if any more ambiguity arises.
