People have different motivations to get along with others in different sociality mental modes (i.e., communal mode and market mode), which might affect social decision-making. The present study examined how these two types of sociality mental modes affect the processing of advice-giving using the event-related potentials (ERPs). After primed with the communal mode and market mode, participants were instructed to decide whether or not give an advice (profitable or damnous) to a stranger without any feedback. The behavioral results showed that participants preferred to give the profitable advice to the stranger more slowly compared with the damnous advice, but this difference was only observed in the market mode condition. The ERP results indicated that participants demonstrated more negative N1 amplitude for the damnous advice compared with the profitable advice, and larger P300 was elicited in the market mode relative to both the communal mode and the control group. More importantly, participants in the market mode demonstrated larger P300 for the profitable advice than the damnous advice, whereas this difference was not observed at the communal mode and the control group. These findings are consistent with the dual-process system during decision-making and suggest that market mode may lead to deliberate calculation for costs and benefits when giving the profitable advice to others.
在不同的社会心理模式（即共同体模式和市场模式）下，人们与他人相处的动机各不相同，这可能会影响社会决策。本研究使用事件相关电位（ERP）来考察这两种社会心理模式如何影响建议给出过程。在启动共同体模式和市场模式后，参与者被要求在没有任何反馈的情况下决定是否给一个陌生人提供建议（有益的或有害的）。行为结果表明，与有害建议相比，参与者更倾向于较慢地向陌生人提供有益建议，但这种差异仅在市场模式条件下观察到。ERP结果表明，与有益建议相比，参与者对有害建议表现出更大的负向N1波幅，并且相对于共同体模式和对照组，市场模式下诱发的P300更大。更重要的是，市场模式下的参与者对有益建议表现出的P300大于有害建议，而在共同体模式和对照组中未观察到这种差异。这些发现与决策过程中的双加工系统一致，并表明市场模式在向他人提供有益建议时可能会导致对成本和收益的刻意计算。
