目光接触的非典型加工是自闭症个体的显著特征之一，但非典型直接注视加工的机制尚不清楚。本研究采用视觉搜索范式考察了自闭症儿童的面部情境是否会影响直接注视检测。参与者被要求检测具有不同凝视方向的干扰物中呈现的目标凝视。目标凝视是直接凝视或转移凝视，这是单独呈现（实验1）或在面部背景下（实验2）。与正常发育的儿童一样，自闭症儿童检测直接注视比转移注视更快，更有效，无论眼睛是否单独出现或在面部中。此外，面部倒置扭曲了正常发育儿童的有效直接凝视检测，但自闭症儿童则不然。这些结果表明，自闭症儿童使用特征信息来检测直接注视，而典型的发展中儿童使用特征信息来检测直接注视。(C)2007年爱思唯尔公司All rights reserved.
Atypical processing of eye contact is one of the significant characteristics of individuals with autism, but the mechanism underlying atypical direct gaze processing is still unclear. This study used a visual search paradigm to examine whether the facial context would affect direct gaze detection in children with autism. Participants were asked to detect target gazes presented among distracters with different gaze directions. The target gazes were either direct gaze or averted gaze, which were either presented alone (Experiment 1) or within facial context (Experiment 2). As with the typically developing children, the children with autism, were faster and more efficient to detect direct gaze than averted gaze, whether or not the eyes were presented alone or within faces. In addition, face inversion distorted efficient direct gaze detection in typically developing children, but not in children with autism. These results suggest that children with autism use featural information to detect direct gaze, whereas typically developing children use configural information to detect direct gaze.
