Abstract The most cognitive person’s activity proceeds in the context of social interactions. The influence of social interactions on brain activity in joint performance, including creative, was the subject of research —since the beginning of the XXI century—the development of hyperscanning technique was carried on (see: Shemyakina, Nagornova, 2021). The two main modes of social interaction for joint problems solution can be distinguished—competition or cooperation. Cooperative and competitive behavior has been explored through various social game models, for example: “Chicken game” (Astolfi et al., 2010, Peng et al., 2021), “Dictator” (Cui et al., 2019), “Ultimatum” (Moore et al., 2021), “Trust” (Tortosa et al., 2013) et al., in which participants were to make an action decision on a partner based on social cues. Solving problems in a group or in pairs on the one hand can be a source of anxiety, for example, in negative feedback conditions (Lu et al., 2019), on the other hand, can increase motivation and involvement in task performance. This is especially important for creative problems solving where the one of the effective technique for improving the efficiency and originality of solutions is the brainstorming (Fink et al., 2010, Xue et al., 2018). The aim of the study was to assess the brain activity dynamics (by event-related potentials and EEG synchronization/desynchronization) in verbal creative tasks performance in the context of competition and cooperation.
