自闭症谱系障碍 (ASD) 的记忆的特点是回忆比识别更困难，并且在帮助回忆时很少使用语义或联想相关性。据报道，有两项实验测试了项目-情境相关性对患有高功能自闭症谱系障碍 (HFA) 的成年人的回忆和识别的影响，并匹配了典型的比较参与者。在这两个实验中，参与者研究了红色矩形内出现的单词，并被告知忽略矩形外出现的上下文单词。上下文单词与研究单词相关或无关。结果表明上下文的相关性。仅增强对典型群体的回忆。然而，两组参与者的相关性增强了认可度。在行为层面上，这些发现证实了任务支持假设 [Bowler, D. M., Gardiner, J. M., & Berthollier, N. (2004)。阿斯伯格综合症的源记忆。 Journal of Autism and Developmental Disorders, 34, 533-542]，其中指出患有 ASD 的个体在记忆测试中会表现出更大的困难，而这些测试对检索提供的支持很少。研究结果扩展了这一假设，表明它在研究项目和附带编码的上下文之间的相关性水平上发挥作用。通过显示相关项目的记忆困难，研究结果也与推测自闭症谱系障碍患者的记忆困难有关内侧颞叶和额叶功能障碍的推测一致。 (c) 2007 Elsevier Ltd. 保留所有权利。
Memory in autism spectrum disorder (ASD) is characterised by greater difficulties with recall rather than recognition and with a diminished use of semantic or associative relatedness in the aid of recall. Two experiments are reported that test the effects of item-context relatedness on recall and recognition in adults with high-functioning ASD (HFA) and matched typical comparison participants. In both experiments, participants studied words presented inside a red rectangle and were told to ignore context words presented outside the rectangle. Context words were either related or unrelated to the study words. The results showed that relatedness of context. enhanced recall for the typical group only. However, recognition was enhanced by relatedness in both groups of participants. On a behavioural level, these findings confirm the Task Support Hypothesis [Bowler, D. M., Gardiner, J. M., & Berthollier, N. (2004). Source memory in Asperger's syndrome. Journal of Autism and Developmental Disorders, 34, 533-542], which states that individuals with ASD will show greater difficulty on memory tests that provide little support for retrieval. The findings extend this hypothesis by showing that it operates at the level of relatedness between studied items and incidentally encoded context. By showing difficulties in memory for associated items, the findings are also consistent with conjectures that implicate medial temporal lobe and frontal lobe dysfunction in the memory difficulties of individuals with ASD.
