Dear fouzia thanks for your reply. But i really dont think that the questions appearing in CSS exam would be asking about this. This is a research article and it has really not found its permanent place in the textbooks of psychology.
Now fpsc will not be asking such a topic in the exam, which is not knows to the general student body.
I still feel that the questions were aksing for soething else, in my own guess maybe its referring to the recent perspectives of psychology, but then I am not really sure about that.
