Despite intricate interactions between emotion and decision making, the underlying cognitive mechanisms that govern their relationship remain elusive. Recent theoretical and empirical advances suggest that preferences in risky decision making can arise from the computation of subjective utility (value-dependent) or direct approach-avoidance action tendencies (value-independent). Here, 48 participants performed two gambling tasks (accept/reject and choice selection tasks) under the emotion manipulation (neutral versus disgust) to investigate how decision context and emotion may influence risk preference via the value-dependent and -independent pathways. The results showed that the decision context affected the degree to which both value-dependent and -independent systems were engaged. Crucially, however, the disgust emotion had a selective effect on participants' choices in the accept/reject task. Furthermore, computational analyses revealed that this specific effect resulted from a reduced propensity to gamble for potential gains by engaging only the value-independent system. These results indicate dissociative effects of decision context and emotion and suggest a specific route by which disgust influences choice preference in risky decision making.

厌恶有选择地抑制了与价值无关的潜在收益的冒险行为。

尽管情绪与决策之间存在复杂的相互作用，但控制它们之间关系的潜在认知机制仍然难以捉摸。近期的理论和经验进展表明，风险决策的偏好可能源于主观效用（与价值有关）的计算或直接避免方法的行动倾向（与价值无关）的计算。在这里，有48位参与者在情绪操纵（中立与厌恶）下执行了两个赌博任务（接受/拒绝和选择选择任务），以研究决策情境和情绪如何通过价值依赖和独立途径影响风险偏好。结果表明，决策环境影响了价值依赖和独立系统都参与的程度。但至关重要的是 厌恶情绪会对参与者接受/拒绝任务的选择产生选择性影响。此外，计算分析表明，这种特定效果是由于仅通过参与价值独立的系统而降低了赌博潜在收益的倾向。这些结果表明了决策情境和情绪的分离作用，并提出了一种厌恶影响风险决策中选择偏好的具体途径。
