Individual versus provided constructs, cognitive complexity and extremity of ratings in person perception

Abstract.— Bruner & Tagiuri's (1954) concept of implicit personality theory, and Kelly's (1955) theory of personal constructs were used as a basis for a hypothesis that an individual's own constructs mediate more differentiated perceptions of other people than constructs provided by the experimenter. The hypothesis was tested by using four indices of cognitive complexity and one index of extremity of ratings to measure differentiation. The individual constructs were derived by using Reptest. The provided constructs were Semantic Differential and Personality Differential scales. The subjects were 36 psychology students. Two experimenters were employed to control experimenter effects. The data did not support the hypothesis but showed that differences between individual constructs and provided constructs are dependent upon which criterion is chosen to contrast the two types of constructs, which indices are used to measure the chosen criterion, and what type of provided constructs are compared with individual constructs.
