摘要
社会排斥广泛存在于社会生活中,并对人们的认知、情感、行为等诸多方面产生严重的消极影响。它会损害个体的认知功能,导致个体不能进行理性的判断和决策。研究发现被排斥的个体在风险决策时倾向于风险寻求。跨期决策和风险决策都与人类的生存和发展息息相关,但目前并不清楚社会排斥是否以及如何影响跨期决策。因此,本研究拟从跨期决策的评估和选择两个阶段展开研究,揭示社会排斥对其的作用机制。并在此基础上,运用tDCS技术激活社会排斥的调节脑区,以改善被排斥个体的跨期决策能力。研究结果将揭示人际情境因素与决策者个人因素对跨期决策的联合作用机制,帮助被排斥者提高跨期决策能力,提高被排斥者的个人成就和生活质量。
Social exclusion exists widely,has a negative impact on human cognition,affection and behavior.It impairs individual’s cognitive function and results in difficulties in making rational judgements and decisions.Studies showed that people who experienced social exclusion tended towards risk seeking in risky decision making.Intertemporal decision-making is a particular type of decision-making and it has high similarity with risk decision-making in theoretical development and neural basis.However,whether and how social exclusion affects intertemporal decision-making is largely unknown.Our research aimed to reveal the potential mechanism of social exclusion that affects the two stages of intertemporal decision-making:evaluation and selection.Additionally,the transcranial direct current stimulation(tDCS,a non-invasive brain stimulation technology)would be applied to stimulate the right ventrolateral prefrontal cortex(rvlPFC)which can regulate a range of negative effects from social exclusion,so as to improve the excluded’s intertemporal decision-making capability.The results of this study would shed light on how interpersonal factors affect the intertemporal choice and how to improve the excludeds’ability of intertemporal decision-making,consequently,benefit their quality of life and personal achievement.
