Prior research has suggested that individuals with Autism Spectrum Disorders (ASD) demonstrate heterogeneity in cognitive efficacy, challenged executive resources but efficient visual processing. These contrasts lead to opposing predictions about visuospatial working memory competency in both ASD and the broader autism phenotype (BAP); compromised by constrained executive processes, but potentially scaffolded by effective visual representation. It is surprising therefore, that there is a paucity of visual working memory (VWM) research in both the ASD and BAP populations, which have focused upon the visual features of the to-be-remembered stimulus. We assessed whether individual differences in VWM were associated with autistic-like traits (ALTs) in the BAP. About 76 children carried out the Visual Just Noticeable Difference task, designed to measure high fidelity feature representation within VWM. ALTs were measured with the Children's Empathy Quotient and Systemizing Quotient. Analyses revealed a significant positive relationship between Systemizing and VWM performance. This complements ASD studies in visual processing and highlights the need for further research on the working memory-long-term memory interface in ASD and BAP populations.

LAY SUMMARY: This study was interested in how well children with high levels of autistic-like traits (ALTs) carry out a task which involved memorizing, for brief time, the precise size of colored shapes. The results suggested that children with high levels of ALTs performed the task relatively well. This finding is in contrast to many previous studies suggest that ALTs are associated with poor memory, and suggests that future research needs to look more finely at how individuals carry out these tasks.
先前的研究表明,自闭症谱系障碍(ASD)患者在认知效能方面存在异质性,他们的执行资源受到挑战,但视觉处理效率较高。这些对比导致了 ASD 和更广泛的自闭症表型(BAP)的视空间工作记忆能力的相反预测;受限于受约束的执行过程,但可能由有效的视觉表现来支撑。因此,令人惊讶的是,在 ASD 和 BAP 人群中,视觉工作记忆(VWM)研究都很少,这些研究都集中在要记住的刺激的视觉特征上。我们评估了 VWM 中的个体差异是否与 BAP 中的类似自闭症特征(ALT)有关。大约 76 名儿童进行了视觉可察觉差异任务,旨在测量 VWM 内的高保真特征表示。ALT 用儿童同理心商数和系统思维商数进行测量。分析显示,系统思维与 VWM 表现呈显著正相关。这补充了 ASD 视觉处理方面的研究,并强调了需要进一步研究 ASD 和 BAP 人群中工作记忆与长期记忆的接口。自闭症研究 2018,11:1494-1499。© 2018 自闭症国际研究协会,威利期刊,公司。
本研究关注具有高水平类似自闭症特征(ALT)的儿童在执行一项需要短暂记住彩色形状精确大小的任务时的表现如何。结果表明,具有高水平 ALT 的儿童相对较好地完成了任务。这一发现与许多先前的研究表明 ALT 与较差的记忆力有关的研究结果形成对比,这表明未来的研究需要更仔细地研究个体如何执行这些任务。
