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.
