There is a rapid increase in the number of individuals with high-functioning autism (HFA). Research on motion perception in HFA has shown deficits in processing motion information at the higher visual cortical areas (V5/middle temporal). Several hypotheses have been put forth to explain these deficits as being due to enhanced processing of small details at the expense of the global picture or as a global integration abnormality. However, there is a lot of variability in the results obtained from experiments designed to study motion in adults with autism. These could be due to the inherent diagnostic differences within even the same range of the autism spectrum and/or due to comparison of different experimental paradigms whose processing by the same visual neural areas could be different. In this review, we discuss the various results on motion processing in HFA, as well as the theories of motion perception in autism.
高功能自闭症(HFA)患者的数量正在迅速增加。对高功能自闭症患者运动感知的研究表明,在较高视觉皮层区域(V5/颞中回)处理运动信息存在缺陷。已经提出了几种假设来解释这些缺陷,认为是由于以全局图像为代价增强了对小细节的处理,或者是由于全局整合异常。然而,在旨在研究自闭症成年人运动的实验中获得的结果存在很大差异。这些差异可能是由于即使在自闭症谱系的相同范围内也存在固有的诊断差异,和/或由于不同实验范式的比较,而相同视觉神经区域对这些范式的处理可能不同。在这篇综述中,我们讨论了高功能自闭症患者运动处理的各种结果,以及自闭症运动感知的理论。
