目标导向控制指导最佳决策，它是一种重要的认知能力，可以防止养成习惯。以前的研究已经发现了一些证据，当健康个体受到压力时，以及在以强迫行为和焦虑为特征的精神疾病中，目标导向的缺陷。在这里，我们测试了目标导向控制是否受到状态焦虑的影响，这可能解释了以前的结果。我们在两个实验（受试者之间N = 88;受试者内N = 50）中对这一假设进行了因果检验，这些实验使用吸入高碳酸气体（7.5%CO2）来诱导健康志愿者的急性焦虑状态。在第三个实验（N = 1413）中，我们使用相关设计来测试现实生活中的焦虑激发事件（恐慌发作，压力事件）是否与受损的目标导向控制相关。在前两个因果关系实验中，我们诱导了一种深刻的焦虑状态，无论是生理上还是心理上，但这并不影响目标导向的表现。在第三个相关性研究中，我们没有发现目标导向控制、恐慌发作或压力性生活事件之间存在关联的证据，也没有发现强迫性特质差异所解释的上述差异。总之，三个互补的实验没有发现证据表明焦虑会损害人类受试者的目标导向控制。
Goal-directed control guides optimal decision-making and it is an important cognitive faculty that protects against developing habits. Previous studies have found some evidence of goal-directed deficits when healthy individuals are stressed, and in psychiatric conditions characterised by compulsive behaviours and anxiety. Here, we tested if goal-directed control is affected by state anxiety, which might explain the former results. We carried out a causal test of this hypothesis in two experiments (between-subject N = 88; within-subject N = 50) that used the inhalation of hypercapnic gas (7.5% CO2) to induce an acute state of anxiety in healthy volunteers. In a third experiment (N = 1413), we used a correlational design to test if real-life anxiety-provoking events (panic attacks, stressful events) are associated with impaired goal-directed control. In the former two causal experiments, we induced a profoundly anxious state, both physiologically and psychologically, but this did not affect goal-directed performance. In the third, correlational, study, we found no evidence for an association between goal-directed control, panic attacks or stressful life eventsover and above variance accounted for by trait differences in compulsivity. In sum, three complementary experiments found no evidence that anxiety impairs goal-directed control in human subjects.
