The reasoning bias of jumping to conclusions (JTC) consists of a tendency to make assumptions having little information.
The aim of this study was to estimate the differences in neuropsychological functioning between recent onset psychotic patients who jump to conclusions and those who do not jump to conclusions.
One hundred and twenty-two patients with a recent onset of a psychotic disorder were assessed with three JTC tasks and a neuropsychological battery exploring verbal learning, memory, attention, psychomotor speed, visuoperceptual abilities, working memory, problem solving, executive functioning.
A total of 29.7% (n=36) of the individuals jumped to conclusions in Task 1, 14.0% (n=17) in Task 2, and 15.7% (n=19) in Task 3. People who jump to conclusions in three tasks scored significantly worse in many neuropsychological domain deficits, including attention (p<0.001-0.020), psychomotor speed (p<0.001), working memory (p<0.001-0.040), and executive functioning (p<0.001-0.042).
The present study demonstrates that JTC is present even in early stages of the illness, and that there is a relationship between JTC and neuropsychological functioning.
仓促下结论的推理偏差（JTC）包括根据少量信息做出假设的倾向。
本研究旨在评估在神经心理学功能方面，存在仓促下结论与不存在仓促下结论的近期首发精神病患者之间的差异。
对 122 名近期首发精神障碍患者进行了 3 项 JTC 任务和神经心理学测试，测试内容包括词语学习、记忆、注意力、精神运动速度、视知觉能力、工作记忆、解决问题能力、执行功能。
共有 29.7%（n=36）的个体在任务 1 中仓促下结论，14.0%（n=17）在任务 2 中仓促下结论，15.7%（n=19）在任务 3 中仓促下结论。在三个任务中仓促下结论的人在许多神经心理学领域缺陷方面的得分明显较差，包括注意力（p<0.001-0.020）、精神运动速度（p<0.001）、工作记忆（p<0.001-0.040）和执行功能（p<0.001-0.042）。
本研究表明，即使在疾病的早期阶段也存在仓促下结论的情况，并且仓促下结论与神经心理学功能之间存在关系。
