摘要

社会神经经济学先前的研究一致报道了互动经济游戏中社会认知区域的激活,这表明在经济选择过程中存在心智化。这种心理化发生在积极参与游戏的过程中,也发生在被动观察他人互动的过程中。我们设计了一个经典错误信念任务(FBT)的新版本,在这个任务中,参与者阅读关于最后通牒和信任游戏中代理人之间相互作用的小片段,随后被要求推断代理人的信念。我们使用关联分析比较了经济博弈FBT和经典FBT期间的激活模式。我们发现,在信念形成和信念推理两个任务阶段,左颞顶交界处(TPJ)和背内侧前额叶皮层以及颞极(TP)存在显著的重叠。此外,广义心理生理相互作用(gPPI)分析表明,在信念形成过程中,右侧TPJ是左侧TPJ和右侧TP种子区域的目标,而在信念推理过程中,所有种子区域都表现出相互联系。这些结果表明,在不同的任务类型和阶段中,心智化与社会认知网络中心节点的激活和连通性有关。重要的是,无论是新的经济游戏还是经典的fbt,都是如此。

Mentalizing in an economic games context is associated with enhanced activation and connectivity in the left temporoparietal junction.

Prior studies in Social Neuroeconomics have consistently reported activation in social cognition regions during interactive economic games, suggesting mentalizing during economic choice. Such mentalizing occurs during active participation in the game, as well as during passive observation of others' interactions. We designed a novel version of the classic false-belief task (FBT) in which participants read vignettes about interactions between agents in the ultimatum and trust games and were subsequently asked to infer the agents' beliefs. We compared activation patterns during the economic games FBT to those during the classic FBT using conjunction analyses. We find significant overlap in the left temporoparietal junction (TPJ) and dorsal medial prefrontal cortex, as well as the temporal pole (TP) during two task phases: belief formation and belief inference. Moreover, generalized Psychophysiological Interaction (gPPI) analyses show that during belief formation, the right TPJ is a target of both the left TPJ and the right TP seed regions, whereas during belief inferences all seed regions show interconnectivity with each other. These results indicate that across different task types and phases, mentalizing is associated with activation and connectivity across central nodes of the social cognition network. Importantly, this is the case for both the novel economic games and the classic FBTs.

期刊介绍: SCAN will consider research that uses neuroimaging (fMRI, MRI, PET, EEG, MEG), neuropsychological patient studies, animal lesion studies, single-cell recording, pharmacological perturbation, and transcranial magnetic stimulation. SCAN will also consider submissions that examine the mediational role of neural processes in linking social phenomena to physiological, neuroendocrine, immunological, developmental, and genetic processes. Additionally, SCAN will publish papers that address issues of mental and physical health as they relate to social and affective processes (e.g., autism, anxiety disorders, depression, stress, effects of child rearing) as long as cognitive neuroscience methods are used.
