Data and Appendix for Original Research Paper "Emotions and Prior Outcomes Shape Risk Propensity and the Dynamics of Decision Making in BART"

Decisions under uncertainty often emerge from the interaction of affective and cognitive processes. Using the Balloon Analogue Risk Task (BART), this study investigated how incidental emotions (happiness, sadness, anger, fear) and prior outcomes shape risk-taking. Sixty-six participants performed the BART while exposed to images evoking emotions or neutral affect. Results revealed that exposure to anger- and fear-evoking stimuli significantly reduced risk-taking, suggesting these highly arousing negative emotions may disrupt engagement and promote avoidance behaviors. Additionally, participants demonstrated heightened risk propensity and prolonged decision times following a successful trial, indicating a cognitive reframing of subsequent decisions after gains. These findings highlight how emotional and contextual cues jointly shape risky behavior in uncertain environments, advancing our understanding of affect-cognition interplay in decision processes.

不确定性情境下的决策往往源于情感与认知过程的交互作用。本研究采用气球模拟风险任务（Balloon Analogue Risk Task, BART），探究偶发情绪（快乐、悲伤、愤怒、恐惧）与先前结果如何塑造风险决策行为。66名参与者在观看诱发情绪或中性情感的图片时完成BART任务。结果显示，观看诱发愤怒和恐惧的刺激显著降低了风险决策行为，表明这些高唤醒的负性情绪可能干扰任务投入并促进回避行为。此外，参与者在成功试次后表现出更高的风险倾向和更长的决策时间，表明收益后对后续决策存在认知重构。这些发现强调了情绪与情境线索如何共同塑造不确定性环境中的风险行为，深化了我们对决策过程中情感-认知交互作用的理解。
