Background and objectives

The tendency of people with schizophrenia to gather insufficient information before making decisions or jumping to conclusions has been repeatedly reported. However, criticism has also been expressed regarding the ecological validity of this finding. Here we present the results obtained by a group of people with schizophrenia and a control group in a non-probabilistic task that requires obtaining items of information before interpreting an ambiguous social situation.

Methods

Patients with schizophrenia (n = 48) and controls (n = 44) aged 18–50 years participated in the study. All subjects completed the Beads Task and the modified Social Information Preference Task.

Results

Patients with schizophrenia showed a statistically significant tendency to jump to conclusions, including in the proposed novel social task. Unlike other studies, we were unable to find a relationship between this bias and greater severity of psychotic symptoms.

Limitations

We did not include patients with high levels of psychotic symptoms or a clinical control group.

Conclusions

The tendency to jump to conclusions in schizophrenia could be present in everyday interpersonal situations.

精神分裂症患者使用较少的信息来解释模棱两可的社会情况

背景和目标

精神分裂症患者在做出决定或草率下结论之前收集信息不足的倾向已被反复报道。然而，也有人对这一发现的生态有效性提出批评。在这里，我们展示了一组精神分裂症患者和一个对照组在一项非概率任务中获得的结果，该任务需要在解释模棱两可的社会情况之前获得信息项。

方法

年龄在 18-50 岁的精神分裂症患者 ( n  = 48) 和对照组 ( n  = 44) 参与了这项研究。所有受试者都完成了珠子任务和修改后的社会信息偏好任务。

结果

精神分裂症患者表现出具有统计学意义的急于下结论的倾向，包括在提议的新社交任务中。与其他研究不同，我们无法找到这种偏见与更严重的精神病症状之间的关系。

限制

我们不包括具有高水平精神病症状的患者或临床对照组。

结论

在精神分裂症中草率下结论的倾向可能存在于日常人际关系中。
