患有自闭症谱系障碍（ASD）的个体通常被描述为具有社会参与和语言缺陷，但视觉空间处理和短期记忆（STM）的保留，有一些证据表明这些领域的表现超正常水平。本研究扩大了这一证据，通过调查的观察学习的视觉空间概念，从模式的协变跨多个exemplars.MethodChild和成人参与者与ASD，和年龄匹配的控制参与者，看到多形状阵列组成的随机组合的形状对，每个都定位在一个固定的空间arrangement.ResultsAfter这个被动暴露阶段，后测显示，所有参与者组可以区分成对的形状与高协变随机配对的形状与低协变。此外，学习这些形状对高协变是上级在成人ASD比年龄匹配的控制，而在儿童ASD的性能是没有什么不同的controls.ConclusionsThese结果扩展到学习领域的ASD的视觉空间增强以前的观察，并表明，增强的视觉统计学习可能源于持续的偏见，以关注复杂的视觉阵列中的局部细节。功能.
ObjectiveIndividuals with autism spectrum disorder (ASD) are often characterized as having social engagement and language deficiencies, but a sparing of visuospatial processing and short-term memory (STM), with some evidence of supranormal levels of performance in these domains. The present study expanded on this evidence by investigating the observational learning of visuospatial concepts from patterns of covariation across multiple exemplars.MethodChild and adult participants with ASD, and age-matched control participants, viewed multishape arrays composed from a random combination of pairs of shapes that were each positioned in a fixed spatial arrangement.ResultsAfter this passive exposure phase, a posttest revealed that all participant groups could discriminate pairs of shapes with high covariation from randomly paired shapes with low covariation. Moreover, learning these shape-pairs with high covariation was superior in adults with ASD than in age-matched controls, whereas performance in children with ASD was no different than controls.ConclusionsThese results extend previous observations of visuospatial enhancement in ASD into the domain of learning, and suggest that enhanced visual statistical learning may have arisen from a sustained bias to attend to local details in complex arrays of visual features.
