Description: In this study, a comparison was made between the various levels of group cognitive complexity and its relationship to task performance and task satisfaction. The goal of this research is to answer the general question, "Should decision-making groups consist of individuals who are similar in the way they differentiate and/or integrate various stimuli in order to increase performance and satisfaction?" The preceding research problem was analyzed in a laboratory setting using a 2 X 2 factorial design blocked on the variable, cognitive complexity. The Repertory Grid was used to measure the cognitive complexity of 228 student subjects. These subjects were stratified into groups of three based on their cognitive complexity score on the Repertory Grid (Kelly, 1955). Each group was treated randomly with one of two levels of task complexity (complex or not complex). Moreover, the groups received an imposedgroup structure that incorporated centralized or decentralized decision-making. Results indicated that groups consisting of cognitively complex members outperformed groups consisting of noncomplex members. No support was obtained for the two-way interaction between group cognitive complexity and either task complexity or group structure. Support was obtained for the interaction between task complexity and group structure on both task satisfaction measures. The highest satisfaction levels occurred with a complex task in a decentralized structure. In addition, the three-way interaction effect on the task satisfaction scale between group structure, task complexity, and group cognitive complexity was significant. The means, however, were not in the predicted direction. For cognitively simple groups, a complex task with a decentralized structure lead to the highest task satisfaction level; whereas, a less complex task with a decentralized group structure lead to the lowest task satisfaction score for noncomplex members. There were no significant differences for cognitively complex groups when analyzing the three-way interaction between group cognitive complexity, task complexity, ...
