Providing eyewitness testimony involves monitoring one's memory to provide a detailed and accurate account: reporting details likely to be accurate and withholding potentially inaccurate details. Autistic individuals reportedly experience difficulties in both retrieving episodic memories and monitoring their accuracy, which has important implications for eyewitness testimony. Thirty autistic and 33 IQ‐matched typically developing (TD) participants viewed a video of a mock bank robbery followed by three phases of questions (with judgments of confidence). In Phase 1, participants freely generated the granularity of their responses (i.e., fine‐ or coarse‐grained). In Phase 2, participants answered the same questions but provided both a fine‐ and a coarse‐grained answer. In Phase 3, participants were instructed to maximize accuracy over informativeness by selecting one of their Phase 2 answers as their final answer. They either received the questions socially (from the experimenter) or answered them online. There were no group differences in accuracy or metacognitive monitoring, with both autistic and TD witnesses demonstrating: (a) a strong preference for reporting fine‐grained details at the expense of accuracy; (b) improved though still suboptimal grain size reporting when instructed to maximize accuracy over informativeness; (c) effective accuracy monitoring; and (d) higher overall accuracy when questions were delivered socially. There was, however, a subtle difference in metacognitive control, with autistic witnesses performing more poorly than TD witnesses when questions were delivered socially, but not when they were delivered online. These findings contrast with evidence suggesting that autism is marked by impairments in episodic memory and metacognitive monitoring and control. Autism Res 2020, 13: 2017‐2029. © 2020 The Authors.

自闭症目击者记忆报告的元认知监测和控制。

提供目击者证词包括监视一个人的记忆以提供详细而准确的记录：报告可能准确的细节并隐瞒可能不准确的细节。据报道，自闭症患者在检索情节记忆和监测其准确性方面均遇到困难，这对目击者的证词具有重要意义。30名自闭症患者和33名智商匹配的典型发展中（TD）参与者观看了一段模拟银行抢劫案的视频，随后是三个阶段的问题（有信心判断）。在阶段1中，参与者可以自由生成其响应的粒度（即细粒度或粗粒度）。在第2阶段，参与者回答了相同的问题，但提供了罚款和粗粒度的答案。在第3阶段，通过选择第2阶段答案之一作为最终答案，指示参与者最大程度地提高信息准确性。他们或者通过社交方式（从实验者那里）收到了问题，或者在线回答了问题。自闭症患者和TD证人均在准确性或元认知监控方面没有群体差异，这表明：（a）强烈希望以准确性为代价来报告细粒度的细节；（b）在指示最大程度地提高信息量的准确性时，尽管仍未达到最佳粒度报告；（c）有效的准确性监控；（d）当社交提出问题时，整体准确性更高。但是，元认知控制方面存在细微的差异，当问题在社交上传递时，自闭症证人的表现要比TD证人差，但在网络上传递时则没有。这些发现与证据表明自闭症的特征在于情节记忆和元认知监测与控制受损。自闭症水库2020年，13：2017至2029年。©2020作者。由Wiley Periodicals，Inc.出版的国际自闭症研究协会出版的《自闭症研究》。
