Abstract: The second cognitive revolution is a postmodern one and it results in the establishment of social constructionism. Social constructionism claims that : (1)knowledge is a product of social construction; (2)mental phenomena like personality, attitude, emotion etc. are not inside people but between people; (3) language is not straightforward expression of thought but a pre-condition for thought; (4) all forms of knowledge are historically and culturally specific; (5) psychologists should give more attention to the function of discourse and discursive analysis may be the basic method of psychology.

Key words: social constructionism, the second cognitive revolution, discourse, psychology
