Iconic memory is the ability to accurately recall a number of items after a very brief visual exposure. Previous research has examined these capabilities in typically developing (TD) children and individuals with intellectual disabilities (ID); however, there is limited research on these abilities in children with Autism Spectrum Disorders (ASD). Twenty-one TD and eighteen ASD children were presented with circular visual arrays of letters for 100 ms and were asked to recall as many letters as possible or a single letter that was cued for recall. Groups did not differ in the number of items recalled, the rate of information decay, or speed of information processing. These findings suggest that iconic memory is an intact skill for children with ASD, a result that has implications for subsequent information processing.
标志性记忆是指在极短的视觉暴露后准确回忆出许多项目的能力。先前的研究已经在典型发育（TD）儿童和智障（ID）个体中研究了这些能力；然而，在自闭症谱系障碍（ASD）儿童中，这些能力的研究有限。21 名 TD 儿童和 18 名 ASD 儿童观看了圆形字母视觉数组，呈现时间为 100 毫秒，并被要求尽可能多地回忆出字母，或回忆出一个被提示的字母。两组在回忆的项目数量、信息衰减率或信息处理速度方面没有差异。这些发现表明，标志性记忆是 ASD 儿童的一项完整技能，这一结果对后续的信息处理有影响。
