摘要

虽然统计学习经常被单独研究,但其通过自他融合的集体表征仍不清楚。本研究使用双人同步记录来研究动态自他整合及其多脑机制。参与者(N = 112)各自重复对固定刺激序列的一半做出反应,并与主动伙伴(联合情境)或被动观察者(基线情境)共同做出反应。在联合情境中,个体统计学习效果显著,表现为反应时间(RT)和脑内神经反应的减少,在插入干扰序列后,反应时间和脑内神经反应呈二次曲线趋势(即先增加后减少)。更重要的是,θ波段的脑-脑耦合(BtBC)也表现出与学习和调制相关的趋势,其斜率分别与反应时间和脑内功能连接的斜率呈负相关和正相关。这些结果凸显了联合统计学习中自体与他体整合的动态性质,统计规律性隐含并自发地调节了这一过程。值得注意的是,BtBC是自他整合动态过程中的一个关键神经相关因子。

Interbrain neural correlates of self and other integration in joint statistical learning.

While statistical learning is often studied individually, its collective representation through self-other integration remains unclear. This study examines dynamic self-other integration and its multi-brain mechanism using simultaneous recordings from dyads. Participants (N = 112) each repeatedly responded to half of a fixed stimulus sequence with either an active partner (joint context) or a passive observer (baseline context). Significant individual statistical learning was evident in the joint context, characterized by decreased reaction time (RT) and intra-brain neural responses, followed by a quadratic trend (i.e., first increasing and then decreasing) upon insertion of an interference sequence. More importantly, Brain-to-Brain Coupling (BtBC) in the theta band also showed learning and modulation-related trends, with its slope negatively and positively correlating with the slopes of RT and intra-brain functional connectivity, respectively. These results highlight the dynamic nature of self-other integration in joint statistical learning, with statistical regularities implicitly and spontaneously modulating this process. Notably, the BtBC serves as a key neural correlate underlying the dynamics of self-other integration.
