Impairment in Theory of mind (TOM) has frequently been associated with schizophrenia and with schizotypy. Studies have found that a tendency to over-attribute intentions and special meaning to events and to people is related to positive psychotic symptoms. Further, it has been suggested that this intentionality bias may be due to a broader deficit in context processing (CP). The aim of the present study was thus to investigate the relationship between positive schizotypy and both over-attribution of intentions and contextual processing.
One-hundred and nineteen healthy individuals completed the Schizotypal Personality Questionnaire and were assessed with tasks measuring contextual treatment and ToM.
Results revealed that positive schizotypy was significantly related to an over-attribution of intentions on the ToM task and with a faster processing of implicit context. Partial correlational analyses indicated that the association between the attribution of intentions and positive schizotypy was not explained by a deficit of CP. In contrast, stepwise multiple regression analyses showed that both an over-attribution of intentions and a faster processing of implicit context significantly predicted positive schizotypy.
These results show that an over-attribution of intention is independent from a broader deficit in context information processing and that they both possibly contribute to the development and maintenance of positive psychotic symptoms.
心理理论（TOM）受损常与精神分裂症及分裂型人格特质相关。研究发现，对事件和他人过度归因意图及特殊意义的倾向与阳性精神病性症状有关。此外，有人提出这种意向性偏差可能源于情境加工（CP）方面更广泛的缺陷。因此，本研究的目的是调查阳性分裂型人格特质与意图过度归因及情境加工之间的关系。
119名健康个体完成了分裂型人格问卷，并通过测量情境加工和心理理论的任务进行评估。
结果显示，阳性分裂型人格特质与心理理论任务中的意图过度归因以及内隐情境的更快加工显著相关。偏相关分析表明，意图归因与阳性分裂型人格特质之间的关联不能用情境加工缺陷来解释。相反，逐步多元回归分析表明，意图过度归因和内隐情境的更快加工都能显著预测阳性分裂型人格特质。
这些结果表明，意图过度归因独立于情境信息加工方面更广泛的缺陷，且二者都可能对阳性精神病性症状的发展和维持有影响。
