Group identification may influence collective behaviors and result in variations performance. However, the evidence for this hypothesis neural mechanisms involved remain elusive. To end, we conducted a study using both single-brain activation multi-brain synchronization analyses to investigate how group influences problem-solving murder mystery case. Our results showed that groups with high levels of performed better individually compared those low identification, as supported by dorsolateral prefrontal cortex (DLPFC). Furthermore, high-identification also enhanced performance, within-group (GNS) orbitofrontal (OFC). The DLPFC-OFC connectivity played crucial role linking individual Overall, our provides two-in-one model explain affects decision-making processes, offering valuable insights into dynamics interactions.

Abstract Divergent thinking is assumed to benefit from releasing the constraint of existing knowledge (i.e. top–down control) and enriching free association bottom–up processing). However, whether functional antagonism between control–related processing–related brain structures conducive generating original ideas largely unknown. This study was designed investigate effect left inferior frontal gyrus right temporoparietal junction on divergent performance. A within-subjects design adopted for three experiments. total 114 participants performed tasks after receiving transcranial direct current stimulation over target regions. In particular, cathodal anodal (Experiment 1), 2), both 3) were manipulated. Compared with sham stimulation, combination hyperpolarization depolarization comprehensively promoted fluency, flexibility, originality without decreasing rationality generated ideas. Functional (hyperpolarization) (depolarization) has a “1 + 1 > 2” superposition thinking.

Collaboration is a critical skill in everyday life. It has been suggested that collaborative performance may be influenced by social factors such as interpersonal distance, which defined the perceived psychological distance between individuals. Previous literature reported close promote level of self-other integration interacting members, and turn, enhance performance. These studies mainly focused on interdependent collaboration, requires high levels shared representations integration. However, little known about effect independent collaboration (e.g., joint Simon task), individuals perform task independently while final outcome determined parties. To address this issue, we simultaneously measured frontal activations ninety-four pairs participants using functional near-infrared spectroscopy (fNIRS)-based hyperscanning technique they performed task. Behavioral results showed Joint Effect (JSE), RT difference incongruent congruent conditions indicating collaborators, was larger friend group than stranger group. Consistently, inter-brain neural synchronization (INS) across dorsolateral medial parts prefrontal cortex also stronger In addition, INS left negatively predicted JSE only suggest mental representation among turn influences their

脑间同步是指在群体互动中，个体之间大脑活动的一致性变化。作为群体互动的固有特征，脑间同步反映了真实互动中的人际联结。随着超扫描技术的发展，研究者提倡采用更真实的参与式研究范式来深入研究脑间同步。近年来，有研究提出相互预测理论，认为脑间同步的关键在于个体对他人的准确预测。这一预测过程与个体将他人纳入自我表征的程度，即自我-他人重叠程度有关。目前关于自我-他人重叠在脑间同步中的作用研究相对较少。因此，本文梳理了近几年采用参与式范式的脑间同步研究，在相互预测理论的基础上，提出自我-他人重叠可能是脑间同步的潜在机制。本文认为，个体通过将他人纳入自我表征，能够促进对他人的准确预测，从而使个体间形成脑间同步。在这一过程中，内侧前额叶皮层可能是关键的神经基础。本文为深入理解群体思想情绪的传递过程提供了启示，强调脑间同步与自我-他人重叠的联系以及内侧前额叶皮层在其中的作用。未来研究可以通过计算建模等方法进一步探索脑间同步的潜在机制，并关注特殊群体中异于常态的同步现象与自我-他人重叠的关联。
