Research on group brainstorming has demonstrated that it is less effective for generating large numbers of ideas than individual brainstorming, yet various scholars have presumed that group idea sharing should enhance cognitive stimulation and idea production. Three experiments examined the potential of cognitive stimulation in brainstorming. Experiments 1 and 2 used a paradigm in which individuals were exposed to ideas on audiotape as they were brainstorming, and Experiment 3 used the electronic brainstorming paradigm. Evidence was obtained for enhanced idea generation both during and after idea exposure. The attentional set of the participant and the content of the exposure manipulation (number of ideas, presence of irrelevant information) influenced this effect. These results are consistent with a cognitive perspective on group brainstorming.
关于群体头脑风暴的研究表明，在产生大量想法方面，它不如个体头脑风暴有效，但许多学者推测群体想法分享应该会增强认知刺激和想法产生。三项实验检验了头脑风暴中认知刺激的潜力。实验1和实验2采用了一种范式，即个体在头脑风暴时通过听录音带接触想法，实验3采用了电子头脑风暴范式。在想法接触期间和之后都获得了想法产生增强的证据。参与者的注意力集中点和接触操作的内容（想法数量、无关信息的存在）影响了这种效果。这些结果与关于群体头脑风暴的认知观点一致。
