Effect of group cohesiveness and training upon creative thinking

Abstract

In the formation of creative thinking groups, how well does brainstorming work? 48 Ss were divided into trained and untrained samples; and cohesive, noncohesive, and "nominal" subgroups of 2 persons each were formed, based on sociometric choice. Several hypothetical problems were discussed. An analysis of variance statistical technique was used to compare number of responses and number of unique responses between the groups. "Brainstorming by pairs of superior adults will produce more unique ideas when the groups are trained in the method and composed of people who like to brainstorm together. This is true, however, only when they are working on ego-involving problems." (PsycInfo Database Record (c) 2025 APA, all rights reserved)
