Abstract

It has been established that typically developing individuals have a bias to attend to facial information in the left visual field (LVF) more than in the right visual field. This bias is thought to arise from the right hemisphere's advantage for processing facial information, with evidence suggesting it to be driven by the configural demands of face processing. Considering research showing that individuals with autism have impaired face processing abilities, with marked deficits in configural processing, it was hypothesized that they would not demonstrate a LVF bias for faces. Eye-tracking technology was used to show that individuals with autism were not spontaneously biased to facial information in the LVF, in contrast to a control group, while discriminating facial gender.

摘要

已经证实,正常发育的个体在左视野(LVF)中比在右视野中更倾向于关注面部信息。这种偏向被认为源于右半球在处理面部信息方面的优势,有证据表明它是由面部处理的整体需求驱动的。考虑到研究表明,自闭症个体的面部处理能力受损,在整体处理方面存在明显缺陷,因此假设他们不会对面部表现出 LVF 偏向。眼动跟踪技术表明,自闭症个体在辨别面部性别时,不像对照组那样自发地偏向 LVF 中的面部信息。
