The Retrieval Of Rewarding Episodic Memory During Decision Increases High Risky Tendency

Risky decision refers to the decision made by an individual when all options have a certain probability to bring losses.The risk level of the option in the decision is proportional to the amount of potential gains or losses.People have the characteristics of risk aversion.However,when people make decisions,they tend to take risks under the influence of some factors,such as the memory retrieval process.Memory has a profound influence on individual decision-making behavior.In reality,individuals usually need memory as a reference to better complete current decision-making.The purpose of this study was to investigate whether and how reward episodic memory affects individual decision risk propensity.Experiment 1 explored the influence of reward item on risk tendency.Experiment 2 discussed the influence of context shared by multiple episodic memory on individual risk tendency,and whether this effect changed with reward episodes experience.Experiment 3 explores whether item can enable individuals to extract reward nature of its context and then influence the current risk decision-making tendency.The results show that :(1)the item information of reward episodic memory in decision making can lead individuals to have higher risk tendency;(2)background source information with the nature of situational reward in decision-making can guide individuals to have a higher risk tendency,and this influence will deepen with the improvement of the nature of background reward;(3)project information in decision-making can enable individuals to extract the situational reward nature of background source information,thus affecting individual decision-making risk tendency.
