Perceived Heterogeneity and Its Effect on Various Types of Tasks.

Abstract

This study investigated the effects of group composition and evaluation instructions on a motor task, a creative-cognitive task and a cognitive decision-making task. An anonymous group technique was used to control for extraneous variables that are frequently present in small group studies. The subjects were 48 females from undergraduate courses at the University of Hawaii. A 2 x 4 (composition X instruction) ANOVA was computed performance on each tasks. A significant main effect for group, showing improvement under perceived heterogeneous affiliation, was found using the creative cognitive dependent variable (p < .05). Significant group x instruction interactions were found for the cognitive decision-making task (p less than .02) and the motor task (p less than .04). These findings are addressed in terms of factors inherent in the composition of the groups and nature of the tasks. Implications for future research are outlined and discussed. Originator supplied keywords include: Heterogeneity, evaluation pay-offs, effect of culture, task analysis.
