Abstract

A near-miss is a situation in which a gambler almost wins but falls short by a small margin, which motivates gambling by making it feel like success is within reach. Existing research has extensively investigated the influence of contextual information on near-miss outcome processing; however, the impact of reward expectancy has received limited attention thus far. To address this gap, we utilized the wheel of fortune task and event-related potential technique (ERP) to quantify the electrophysiological responses associated with gambling outcomes at different levels of reward expectancy. Behaviorally, near-miss outcomes elicited a greater occurrence of counterfactual thoughts, feelings of regret, and heightened anticipation of rewards for subsequent trials compared to full-miss outcomes. ERP findings indicated that in contrast to full-miss outcomes, near-miss outcomes diminished feedback-related negativities (FRNs) and amplified P300s when reward expectancy was low, but amplified FRNs and diminished P300s when reward expectancy was high. These findings provide valuable insights into the neural mechanisms underlying the processing of outcome proximity and reward expectancy.

奖励预期对近乎失误结果处理的调节：ERP研究

近乎失利是指赌徒几乎赢钱但以微弱差距落败的情况，这种情况会让人感觉成功近在咫尺，从而激发赌徒的赌性。现有研究已广泛调查了上下文信息对 "近乎失败 "结果处理的影响，但迄今为止，人们对奖励预期的影响关注有限。为了填补这一空白，我们利用幸运大转盘任务和事件相关电位技术（ERP）量化了不同奖励预期水平下与赌博结果相关的电生理反应。从行为上看，与全输的结果相比，近乎全输的结果会引起更多的反事实想法、后悔情绪以及对后续试验奖励的更高预期。ERP研究结果表明，与完全失误结果相反，当奖励预期较低时，近乎失误的结果会降低反馈相关负性（FRNs）并放大P300s，但当奖励预期较高时，反馈相关负性（FRNs）会放大，P300s会降低。这些发现为研究结果接近性和奖励预期的神经机制提供了有价值的见解。

期刊介绍： Biological Psychology publishes original scientific papers on the biological aspects of psychological states and processes. Biological aspects include electrophysiology and biochemical assessments during psychological experiments as well as biologically induced changes in psychological function. Psychological investigations based on biological theories are also of interest. All aspects of psychological functioning, including psychopathology, are germane. The Journal concentrates on work with human subjects, but may consider work with animal subjects if conceptually related to issues in human biological psychology.
