The influence of emotion on episodic and autobiographical memory in schizophrenia was investigated. Using an experiential approach, the states of awareness accompanying recollection of pictures from the IAPS and of associated autobiographical memories was recorded. Results show that schizophrenia impairs episodic and autobiographical memories in their critical feature: autonoetic awareness, i.e., the type of awareness experienced when mentally reliving events from one's past. Schizophrenia was also associated with a reduction of specific autobiographical memories. The impact of stimulus valence on memory performance was moderated by clinical status. Patients with schizophrenia recognized more positive than negative pictures, and recalled more positive than negative autobiographical memories while controls displayed the opposite pattern. A hypothesis in terms of a fundamental executive deficit underlying these impairments is proposed.
研究了情感对精神分裂症患者情景记忆和自传体记忆的影响。采用体验式方法，记录了回忆国际情感图片系统（IAPS）中的图片及相关自传体记忆时伴随的意识状态。结果表明，精神分裂症损害情景记忆和自传体记忆的关键特征：自我觉知意识，即当在脑海中重温过去事件时所体验到的意识类型。精神分裂症还与特定自传体记忆的减少有关。刺激效价对记忆表现的影响受临床状态调节。精神分裂症患者识别出的积极图片多于消极图片，回忆出的积极自传体记忆也多于消极自传体记忆，而对照组则呈现相反模式。提出了一个关于这些损害背后存在基本执行功能缺陷的假说。
