| Risk-taking decision making is one of the most frequent activities in our daily life.When facing risky decisions,people often take the past experience as a reference,and then make reasonable and favorable decisions.Episodic specificity induction（ESI）is a pathway that activates episodic memory function and can affect individuals’ performance in subsequent decision making.Constructive episodic simulation hypothesis provides a corresponding theoretical explanation,and this theory has been supported by many empirical studies.In recent years,more and more researchers have begun to focus on the relationship between ESI and Risk-taking decision making from the relationship between ESI and individuals’ creativity and imagination,and they have drawn inconsistent conclusions.The topic of the relations between ESI and Risk-taking decision making has yet to be unresolved by researchers.Individuals’ risk decision-making is the result of the joint influence of internal and external factors.Through consulting and combing literatures,inhibitory control may affect individuals’ risk decision-making,but the risk decision-making paradigm may also be the factor that leads to different results.Therefore,the most widely used risk decision-making paradigm,namely the Balloon Analogue Risk Task（BART）and the Iowa Gambling Task（IGT）,were adopted in this study.Inhibitory control is closely related to episodic memory function and risk decision-making,but the relationship between the three has not been studied yet.For the above reasons,based on the Constructive episodic simulation hypothesis,this study considers the effect of behavioral inhibition and cognitive inhibition on the relationship between ESI and risk decision-making（BART/IGT）respectively,to explores the psychological mechanism of individuals’ action on risk decision making.This study consisted of four formal experiments.In Experiment 1,To explore the relationship between ESI,behavioral inhibitory control and risk decision-making,we select the BART as evaluation index of the risk decision,using 2（induction）× 2（inhibitory conditions）two factors between subject’s design and control emotion,self-control and trait coping style as control variables.The results show that behavioral inhibitory control can predict risk decision making after controlling for additional variables.Behavioral inhibitory control could mediate the relationship between ESI and risk decision making.In Experiment 2,we examined the effect of cognitive suppression on the relationship between ESI and risk-taking behaviors,and found that,consistent with behavioral suppression,cognitive suppression also reduced the level of risk-seeking in individuals compared with the control group without inhibition.To further explore the role of inhibitory control in different risk decision-making paradigms,in Experiment 3,IGT was selected as the evaluation index of risk decision-making,and a 2（induction mode）×2（inhibition condition）two-factor design was also adopted among subjects.The results showed that cognitive inhibition did not mediate between situational specificity and risk-taking behavior,but the frequency of punishment and the amount of immediate reward could influence the level of risk.In Experiment 4,the relationship between ESI and risk behavior under behavioral inhibition was investigated.The results showed that,consistent with cognitive inhibition,behavioral inhibition did not mediate the relationship between ESI and risk behavior,but the frequency of punishment and the amount of immediate reward also affected individual risk level.In sum,this study drew the following conclusions:（1）In BART,the performance of risk-taking in the specific induction group was significantly higher than that in the general impression induction group without inhibitory control regulation,while there was no significant difference in the level of risk-taking between the specific induction group and the general impression induction group in the IGT.（2）In BART,behavioral inhibition control can regulate the relationship between episodic specificity and risky behaviors.The level of risk-taking in the specification-induced non-inhibition group was significantly higher than that in the specification-induced non-inhibition group,and the level of risk-taking in the general impression-induced non-inhibition group was significantly lower than that in the general impression-induced non-inhibition group.（3）In BART,under specific induction,both behavioral inhibition and cognitive inhibition could significantly reduce individuals’ risk-taking level compared with the non-inhibition group,but there was no significant difference in risk-taking level between the cognitive inhibition group and the behavioral inhibition group.In IGT,both behavioral and cognitive suppression were not associated with levels of situational specificity and risk-taking. |
