Abstract:
Objective:To explore the effect of the retrieval of previous rewarding episodic memories on current decision-making risk preference under negative and neutral emotional contexts.Methods:Thirty-three undergraduate college students from Henan Medical University were selected as subjects in May 2025. A two-option gambling paradigm was selected as the experimental task, and a two-factor within-subject experiment design of 2 (reward: rewarded, non-rewarded) × 2 (emotional background: negative, neutral) was adopted. The risk decision-making rate of the participants was recorded.Two-factor analysis of variance was conducted using SPSS 22.0 software.Results:There was a significant interaction between the reward of the item and the emotional background on risk decision-making rate ( F(1, 64)=6.67, P<0.05, ηP2=0.17). Under the negative and neutral emotional backgrounds, the high-risk selection rates for the rewarded items (0.60±0.22, 0.56±0.22) were significantly higher than those for non-rewarded items (0.30±0.18, 0.33±0.22) (both P<0.01). Additionally, the difference in high-risk choice rate between the rewarded and non-rewarded items under the negative emotional condition (0.30±0.28) was significantly greater than those under the neutral emotional condition (0.23±0.30) ( t(32)=2.451, P<0.05, d’=0.87). Conclusion:Different emotional backgrounds and reward-related episodic memories can influence the risk decision-making preference of individuals together.The retrieval of the rewarding episodic memory during decision making can increase the high risk propensity of the individuals.
