Evidence has been put forward that premature termination of data collection and jumping to conclusions behavior (JTC) is associated with delusions. However, few investigations have attempted to track associations between changes in delusions and changes in JTC measures. In the current study individuals with schizophrenia spectrum disorders completed a version of the JTC task (involving fishing from lakes as opposed to drawing beads from a jar) at two timepoints 12 weeks apart. The results revealed significant negative correlations between change in task performance (number of requested pieces of information) and change in delusion scores over time. This evidence is consistent with the contention that the JTC task is sensitive to the cognitive systems underlying delusions in schizophrenia spectrum disorders.
已经有证据表明，数据收集过早终止和草率下结论行为（JTC）与妄想有关。然而，很少有研究试图追踪妄想变化和 JTC 测量变化之间的关联。在目前的研究中，精神分裂症谱系障碍患者在相隔 12 周的两个时间点完成了 JTC 任务的一个版本（涉及从湖中钓鱼而不是从罐中抽取珠子）。结果表明，任务表现（请求的信息量）的变化与妄想分数随时间的变化之间存在显著的负相关。这一证据与 JTC 任务对精神分裂症谱系障碍中妄想的认知系统敏感的观点一致。
