Current predictive processing accounts consider negative affect to result from elevated rates of prediction error, thereby motivating changes in the degree with which prior expectancies and sensory evidence influence our perceptions. Trait anxiety is associated with the amount of negative affect a person is experiencing and has been linked to aberrant strategies in decision making and belief updating. Here, we assessed the degree to which induced prior expectancies influenced motion judgements in a simple perceptual decision making task in 117 healthy participants with varying levels of trait anxiety. High trait anxious individuals showed increased usage of priors, independent from the amount of sensory uncertainty that was perceived. This finding demonstrates aberrant strategies of belief updating in anxiety even in evaluating nonthreatening visual motion stimuli, and thus suggest an influential role of affective traits in processes of perceptual inference.
当前的预测加工理论认为，负性情绪是由于预测误差率升高而产生的，从而促使先前的期望和感官证据对我们的感知产生影响的程度发生变化。特质焦虑与个体正在经历的负性情绪的多少有关，并与决策和信念更新中的异常策略有关。在这里，我们评估了在一项简单的感知决策任务中，在具有不同特质焦虑水平的 117 名健康参与者中，诱导的先验期望在多大程度上影响了运动判断。高特质焦虑个体表现出更多地使用先验，而与感知到的感官不确定性的多少无关。这一发现表明，即使在评估非威胁性视觉运动刺激时，焦虑症患者的信念更新策略也存在异常，因此表明情感特质在感知推理过程中起着重要作用。
