Abstract

Humans are social creatures, and many tasks in our daily lives are solved together. The two main forms of social interaction in problem solving could be defined as competition and cooperation. In our study, we compared the ERS/ERD when performing a creative task (Alternative Uses Test, AUT) and a control task ("naming the objects from the presented category") under competitive conditions in dyads (22 dyads, m-m, f-f, 18-23 years old) compared to the performance of tasks individually. The number of answers given by subjects under competitive conditions was significantly lower than during the execution of the tasks individually. The solving of the creative task in competition versus individual performance was accompanied by EEG synchronization (9-30 hz) clusters: 140-1220 ms and 900-1780 ms after stimulus presentation; 13.5-30 hz (1800-1980 ms), reflecting the creative thinking mode, and expected cognitive, emotional answers' assessment. The control task under competitive conditions was accompanied by pronounced synchronization of low frequencies in the frontal areas (2-7 hz, 0-1980 ms), due to a greater working memory load; synchronization clusters in broadband (10-30 hz, 100-320 ms, 400-860 ms) and in the beta EEG band (17-30 hz, 1140-1980 ms). The competitive conditions significantly modulated the brain activity underlying creative and non-creative cognitive task performance, and resulted in greater induced EEG synchronization.

口头创作过程中的竞争对 ERS/ERD 有影响。

人类是社会性动物，日常生活中的许多任务都是共同解决的。在解决问题的过程中，社会互动的两种主要形式可定义为竞争和合作。在我们的研究中，我们比较了受试者在竞争条件下（22 人，男-女，女-男，18-23 岁）完成一项创造性任务（"替代性用途测试"，AUT）和一项控制性任务（"说出所呈现类别中的物品名称"）时的 ERS/ERD 与单独完成任务时的 ERS/ERD。在竞争条件下，受试者给出的答案数量明显低于单独完成任务时的答案数量。创造性任务的解题过程中，脑电图同步（9-30 赫兹）群组的时间分别为 140-1220 毫秒和 900-1780 毫秒：刺激呈现后 140-1220 毫秒和 900-1780 毫秒；13.5-30 赫兹（1800-1980 毫秒），反映了创造性思维模式和预期的认知、情感答案评估。竞争条件下的控制任务伴随着额叶区（2-7 赫兹，0-1980 毫秒）明显的低频同步，这是由于工作记忆负荷更大；同步群在宽带（10-30 赫兹，100-320 毫秒，400-860 毫秒）和贝塔脑电图波段（17-30 赫兹，1140-1980 毫秒）。竞争条件极大地调节了创造性和非创造性认知任务表现的大脑活动，并导致更大的诱导脑电图同步。

期刊介绍： Social Neuroscience features original empirical Research Papers as well as targeted Reviews, Commentaries and Fast Track Brief Reports that examine how the brain mediates social behavior, social cognition, social interactions and relationships, group social dynamics, and related topics that deal with social/interpersonal psychology and neurobiology. Multi-paper symposia and special topic issues are organized and presented regularly as well. The goal of Social Neuroscience is to provide a place to publish empirical articles that intend to further our understanding of the neural mechanisms contributing to the development and maintenance of social behaviors, or to understanding how these mechanisms are disrupted in clinical disorders.
