What is a school of thought?

refers to a group of psychologists who become associated ideologically, and sometimes geographically, with the leader of the movement

- members share a theoretical or systematic orientation and investigate similar problems

- more than one can occur simultaneously

- usually led by charismatic leader (e.g. Wilhelm Wundt)

- cyclical nature: mind-body & nature-nurture

early schools of thought were protest movements against a prevailing systematic position, criticizing the older system
