Previous studies have been inconsistent in demonstrating a relationship between delusion proneness and induced stress on reasoning biases. The present study was an experimental investigation of the role of stress in the form of feeling rushed, which has previously been shown to be related to the jumping-to-conclusions reasoning bias for delusion-prone individuals, on the reasoning of delusion-prone individuals. University students (n = 133) completed a measure of delusion proneness and were randomly assigned to either receive or not receive a stress induction in the form of a speeded subtraction task. All participants engaged in four trials of a probabilistic reasoning task. Delusion-prone and not delusion-prone participants performed similarly when there was no stress induction, but delusion-prone individuals demonstrated reasoning biases relative to not delusion-prone individuals when stress was induced. The reasoning of delusion-prone individuals may be particularly vulnerable when they feel rushed and in stressful conditions.
先前的研究在证明妄想倾向与推理偏差的诱导压力之间的关系方面一直存在不一致。本研究是对压力在匆忙感形式下的作用的实验研究，先前的研究表明，匆忙感与妄想倾向个体的跳跃式结论推理偏差有关，而这种偏差与妄想倾向个体的推理有关。大学生（n=133）完成了一项妄想倾向的测量，并被随机分配接受或不接受以加速减法任务形式的压力诱导。所有参与者都进行了四次概率推理任务的试验。在没有压力诱导的情况下，有妄想倾向和没有妄想倾向的参与者表现相似，但在诱导压力时，有妄想倾向的个体表现出相对于没有妄想倾向的个体的推理偏差。当有压力和匆忙感时，妄想倾向个体的推理可能特别脆弱。
