中文摘要： 自我-他人决策差异逐渐成为决策领域研究的热点问题之一。然而，目前研究在采用的任务、得到的发现及理论解释上均存在诸多不一致的地方，且缺乏对此种现象深层心理及脑神经机制的探索。虽然一些研究者试图用心理距离假设来解释相关结果，但由于对心理距离的实验操纵手段过于简单和单一，难以形成解释力较强的理论模型。本项目将在前人研究和项目组前期工作基础上，采用行为实验、信息板技术、功能性核磁共振（fMRI）手段，从改变社会距离到直接操纵心理距离，再到操纵决策者角色，观测和采集风险偏好、线索偏好、认知方式和脑区变化的指标，以深入揭示自我-他人决策差异的心理及脑神经机制。这不仅有助于深化对自我-他人决策差异的理解，而且有助于澄清决策研究领域的一些基础理论问题。

英文摘要： Self-other differences in decision-making gradually become one of the hot issues in decision-making research domain. However, the present studies still have many inconsistencies in the used task, the related findings and theoretical explanations, and lack of exploration of the deep psychological mechanisms and neural basis of this phenomenon. Although some researchers have tried to explain the research results using the psychological distance hypothesis, the means of manipulation of psychological distance in the experimental is still too simple and single to form a form a general theoretical model. This project will be based on previous studies and preliminary work of our team, use behavioral experiments, information board technology and functional magnetic resonance imaging (fMRI) as means, from manipulation of the social distance to the manipulation of psychological distance, then to manipulation of the decision-makers' roles, observe and collect indicators from risk preferences, clues preferences, cognitive modes and changes of brain regions, so as to reveal the psychological mechanism and cognitive neural basis of self-others differences in decision-making. This not only helps to deepen the understanding of the self-other decision differences, but also helps to clarify some basic theoretical issues in the de
