我们社会环境的可控性对我们的行为和心理健康有着深刻的影响。然而，社交可控性背后的神经计算机制仍然难以捉摸。在这里，48名参与者完成了一项任务，他们当前的选择要么(可控)，要么不(不可控)，影响合作伙伴未来的提案。计算模型显示，在可控和不可控的情况下，人们采用了一种前瞻思维的心理模型(FT；即计算当前行为的下游影响)来估计社会可控性。一项大规模的在线复制研究(n=1342)支持这一发现。使用功能磁共振成像(n=48)，我们进一步证明了腹内侧额叶皮质(VmPFC)计算了前瞻计划中当前动作的投影总值，支持了前瞻思维模型的神经实现。这些发现表明，人类使用依赖vmPFC的FT来估计和利用社会可控性，从而将这种神经计算机制的作用扩展到空间和认知背景之外。
The controllability of our social environment has a profound impact on our behavior and mental health. Nevertheless, neurocomputational mechanisms underlying social controllability remain elusive. Here, 48 participants performed a task where their current choices either did (Controllable), or did not (Uncontrollable), influence partners’ future proposals. Computational modeling revealed that people engaged a mental model of forward thinking (FT; i.e., calculating the downstream effects of current actions) to estimate social controllability in both Controllable and Uncontrollable conditions. A large-scale online replication study (n=1342) supported this finding. Using functional magnetic resonance imaging (n=48), we further demonstrated that the ventromedial prefrontal cortex (vmPFC) computed the projected total values of current actions during forward planning, supporting the neural realization of the forward-thinking model. These findings demonstrate that humans use vmPFC-dependent FT to estimate and exploit social controllability, expanding the role of this neurocomputational mechanism beyond spatial and cognitive contexts.
