The influence of alcohol on cognitive conflict.
The influence of alcohol on cognitive conflict between individuals was studied by means of an experiment that was designed to be representative of real life negotiating situations, where alcohol is consumed and where two parties are required to find new common solutions to problems that they have previously learned to solve differently by themselves. The subjects were 60 male students of technology divided into experimental and control groups. The amount of alcohol (whisky) consumed by the experimental subjects produced approximately 0.08% blood alcohol concentration. In the experiment, the cognitive conflict situation was created by first training subjects to solve diagnostic medical tasks…
Individual versus provided constructs, cognitive complexity and extremity of ratings in person perception.
.— 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 no…
Structural representations of person perception A comparison between own and provided constructs
.— The dimensions of perceiving other people were compared from two types of data, one representing a person's individual constructs and indexed by two different rating methods (Reptest technique and Similarity Ratings), the other constructs provided by the experimenter, also measured by two methods (Semantic Differential and Personality Differential). Thirty-one female psychology students, rated fifteen role figures by using the four methods. Indices of factorial and cluster similarity of roles showed that the different rating methods yielded highly similar role structures. Each congruent factor and cluster could also be characterized by identical trait properties, but there were also impo…
The convergent validity of four indices of congnitive complexity in person perception. A multi-index multimethod and factor analytical approach.
.— An application of the Campbell and Fiske multimethod-multitrait analysis and factor analysis was used to study the convergent validity of the following indices of cognitive complexity: Bieri's Index, Vannoy's Interaction Variance Measure, Number of Factors, and First Factor Percentage. In the analysis the individual constructs elicited by Reptest were contrasted with two sets of provided constructs, namely Semantic Differential and Personality Differential scales. The subjects were 36 psychology students. The results indicated that the convergent validity of the indices over construct type was low and that the construct type had an effect upon the intercorrelations of different indices o…
