The looking behavior of children with pervasive developmental disorder (PDD) and age- and IQ-matched normal control children was studied using infrared oculography. Stimuli varying in complexity and topic were presented to test whether children with PDD have specific abnormalities in looking behavior to complex stimuli and/or to faces. All children showed more and longer fixations on the complex objects than on the simple objects, especially the complex nonsense figure, but group differences were not found. The results show no evidence for specific abnormalities in looking behavior to either faces or to complex stimuli in high functioning children with PDD.
利用红外眼动描记术对广泛性发育障碍（PDD）儿童以及年龄和智商匹配的正常对照儿童的注视行为进行了研究。呈现了复杂度和主题各异的刺激物，以测试PDD儿童在注视复杂刺激物和/或面部时的注视行为是否存在特定异常。所有儿童对复杂物体的注视次数更多、时间更长，尤其是对复杂的无意义图形，但未发现组间差异。结果表明，没有证据表明高功能PDD儿童在注视面部或复杂刺激物时的注视行为存在特定异常。
