Recent studies of cognitive processes associated with persecutory delusions suggest that such delusions are associated with abnormalities in the processing of information relevant to the self. Attention to positive and negative trait words was studied in subjects suffering from persecutory delusions, matched subjects with depressed mood and normal controls using an emotional Stroop task. Subjects were required to name the ink colours of: (i) meaningless strings of Os, (ii) low self-esteem personal adjectives, (iii) high self-esteem adjectives and (iv) neutral adjectives. subjects were also asked to rate the degree to which they endorsed as self-descriptive these and other personally descriptive adjectives. The subjects with persecutory delusions demonstrated a significantly higher rate of endorsement for positive adjectives than negative adjectives, but showed a marked degree of interference when colour-naming both positive and negative words. The relevance of these findings to a model of persecutory delusions involving the self-concept is discussed.
近期关于与被害妄想相关的认知过程的研究表明，此类妄想与自我相关信息处理异常有关。利用情绪斯特鲁普任务，对患有被害妄想症的受试者、情绪抑郁的匹配受试者以及正常对照组进行了对积极和消极特质词的注意力研究。受试者被要求说出以下内容的墨水颜色：(i) 由字母O组成的无意义字符串，(ii) 低自尊的个人形容词，(iii) 高自尊的形容词，以及(iv) 中性形容词。受试者还被要求对他们认为这些及其他个人描述性形容词适用于描述自己的程度进行评分。患有被害妄想症的受试者对积极形容词的认同率显著高于消极形容词，但在对积极和消极词汇进行颜色命名时均表现出明显的干扰。本文讨论了这些发现与涉及自我概念的被害妄想模型的相关性。
