Influence of brainstorming instructions and problem sequence on a creative problem solving test.

"The experiment was designed to study the effects on creative problem solving of instructions to express solutions without evaluation (brainstorming) and instructions which required only solutions of good quality and which involved a penalty for solutions of bad quality (nonbrainstorming). Each S [32 college students] was given two problems which required creative ability, in two testing periods." One was with and one without brainstorming. "Significantly more good solutions were produced under brainstorming… . There was no significant difference in the nonbrainstorming performance in the two test periods."
