Recent empirical findings suggest a significant influence of emotion on memory processes. Surprisingly, although emotion-processing difficulties appear to be a hallmark feature in autism spectrum disorders (ASD), their impact on higher-level cognitive functions, such as memory, has not been directly studied in this population. The aim of this study was to address this issue by assessing whether the emotional valence of visual scenes affects recall skills in high-functioning individuals with ASD. To this purpose, their recall performance of neutral and emotional pictures was compared with that of typically developing adults (control group). Results revealed that while typically developing individuals showed enhanced recall skills for negative relative to positive and neutral pictures, individuals with ASD recalled the neutral pictures as well as the emotional ones. Findings of this study thus point to reduced influence of emotion on memory processes in ASD than in typically developing individuals, possibly owing to amygdala dysfunctions.
最近的实证研究结果表明,情绪对记忆过程有显著影响。令人惊讶的是,尽管情绪处理困难似乎是自闭症谱系障碍(ASD)的一个标志性特征,但情绪对诸如记忆等高级认知功能的影响在该人群中尚未得到直接研究。本研究的目的是通过评估视觉场景的情感效价是否会影响高功能自闭症患者的回忆能力来解决这一问题。为此,将他们对中性和情感图片的回忆表现与正常发育的成年人(对照组)进行了比较。结果显示,正常发育的个体对负面图片的回忆能力相对于正面和中性图片有所增强,而自闭症患者对中性图片和情感图片的回忆情况相同。因此,本研究结果表明,与正常发育的个体相比,情绪对自闭症患者记忆过程的影响较小,这可能是由于杏仁核功能障碍所致。
