Automatic attention cueing by perceived changes in gaze direction was studied in 2-year-old children with autism and typically developing (TD) controls using a visual attention cueing paradigm. In Experiments 1 and 2 the cue consisted of an eye movement (Eyes) and a nonbiological movement (SimEyes), respectively. The results suggest that visual attention in children with autism and their TD counterparts is cued by perceived eye movement. Thus, although in naturalistic situations toddlers with autism do not follow the gaze of others, they are sensitive to directional cues inherent in eye movement. Cue-specific differences in performance related to the level of engagement and cue-processing time may suggest reliance on different underlying strategies for gaze processing in autism.
利用视觉注意力提示范式,对患有自闭症的2岁儿童和发育正常(TD)的对照组进行了研究,以探讨由感知到的注视方向变化所引发的自动注意力提示。在实验1和实验2中,提示分别由眼球运动(眼睛)和非生物运动(模拟眼睛)组成。结果表明,自闭症儿童及其发育正常的同龄人在视觉注意力方面是由感知到的眼球运动所提示的。因此,尽管在自然情境中,患有自闭症的幼儿不会跟随他人的目光,但他们对眼球运动中固有的方向提示很敏感。与参与程度和提示处理时间相关的提示特定表现差异,可能表明自闭症患者在注视处理中依赖于不同的潜在策略。
