Paranoid thinking has been linked to greater availability in memory of past threats to the self. However, remembered experiences may not always closely resemble events that trigger paranoia, so novel explanations must be elaborated for the likelihood of threat to be determined. We investigated the ability of paranoid individuals to construct explanations for everyday situations and whether these modulate their emotional impact.
Twenty-one participants experiencing paranoia and 21 healthy controls completed a mental simulation task that yields a measure of the coherence of reasoning in everyday situations.
When responses featured positive content, clinical participants produced less coherent narratives in response to paranoid themed scenarios than healthy controls. There was no significant difference between the groups when responses featured negative content.
The current study suggests that difficulty in scenario construction may exacerbate paranoia by reducing access to non-threatening explanations for everyday events, and this consequently increases distress.
偏执思维与记忆中过去对自身的威胁更容易浮现有关。然而，记忆中的经历可能并不总是与引发偏执的事件非常相似，因此必须阐述新颖的解释来确定威胁的可能性。我们研究了偏执个体构建日常情境解释的能力，以及这些解释是否会调节其情感影响。
21名患有偏执症的参与者和21名健康对照者完成了一项心理模拟任务，该任务可衡量日常情境中推理的连贯性。
当回答具有积极内容时，临床参与者针对偏执主题情景给出的叙述连贯性低于健康对照者。当回答具有消极内容时，两组之间没有显著差异。
当前研究表明，情景构建困难可能会通过减少对日常事件的非威胁性解释而加剧偏执，从而增加痛苦。
