Abstract

This study examines the effects of social interaction conditions on brain correlates of verbal creativity. A model of cooperation is considered in the study in which participants were to work together without conversation and create as many answers as possible in creative and noncreative tasks. Subjects (4 males, 26 female) performed two types of tasks individually and cooperatively in pairs (male-male, female-female): creative task—to create as many as possible unusual use of an everyday object, and noncreative task—to list items from the proposed categories. Event-related potentials (ERPs) in each of the tasks were compared between the cooperative and individual performance conditions. The cooperative conditions demonstrated decrease in the amplitude of the P200 component at a time interval of 148–272 ms from the onset of stimulus presentation for both creative and noncreative tasks performance, reflecting reduced attention allocation to the stimulus in the social interaction condition. When performing a creative task, a larger amplitude of the late positive component was observed in the 662–1240 ms interval in the posterior temporal and occipital areas, which may reflect activation of the temporoparietal junction involved in the processes of understanding the other. The number of answers (productivity) was significantly lower in cooperative conditions compared to individual task performance.

合作对口头创造性任务和非创造性任务表现中的事件相关电位的影响

摘要本研究探讨了社会交往条件对大脑语言创造力相关因素的影响。研究中考虑了一种合作模式，让被试在没有交谈的情况下共同完成创造性和非创造性任务，并尽可能多地创造出答案。受试者（4 名男性，26 名女性）分别单独和结对（男性-男性，女性-女性）合作完成了两种任务：创造性任务是尽可能多地使用日常物品；非创造性任务是从建议的类别中列出物品。在每项任务中，我们都比较了合作和个人表现条件下的事件相关电位（ERP）。在执行创造性任务时，在后颞区和枕区的 662-1240 毫秒时间间隔内观察到较大的晚期阳性成分振幅，这可能反映了颞顶交界处参与理解他人过程的激活。与单独完成任务相比，合作条件下的答案数量（生产率）明显较低。
