This study investigated semantic and episodic memory in autism spectrum disorder (ASD), using a task which assessed recognition and self-other source memory. Children with ASD showed undiminished recognition memory but significantly diminished source memory, relative to age- and verbal ability-matched comparison children. Both children with and without ASD showed an "enactment effect", demonstrating significantly better recognition and source memory for self-performed actions than other-person-performed actions. Within the comparison group, theory-of-mind (ToM) task performance was significantly correlated with source memory, specifically for other-person-performed actions (after statistically controlling for verbal ability). Within the ASD group, ToM task performance was not significantly correlated with source memory (after controlling for verbal ability). Possible explanations for these relations between source memory and ToM are considered.
本研究使用一项评估识别和自我-他人源记忆的任务，对自闭症谱系障碍（ASD）患者的语义记忆和情景记忆进行了调查。相对于年龄和语言能力匹配的对照儿童，ASD儿童的识别记忆未受损，但源记忆显著受损。患有和未患有ASD的儿童均表现出“动作效应”，即自我执行动作的识别和源记忆显著优于他人执行的动作。在对照组中，心理理论（ToM）任务表现与源记忆显著相关，特别是对于他人执行的动作（在对语言能力进行统计控制之后）。在ASD组中，ToM任务表现与源记忆无显著相关性（在控制语言能力之后）。文中考虑了源记忆与ToM之间这些关系的可能解释。
