在自闭症谱系障碍（ASD）的早期发展中，自发注意力部署在毫秒级尺度上的差异知之甚少。我们测量了6至9个月大的ASD高或低家族风险（HR/LR）婴儿在观看静态图像时的细粒度眼球运动模式。我们观察到HR婴儿的注视持续时间（即扫视之间的时间间隔）比LR婴儿短。初步分析表明，这些结果在第二组婴儿中得到了重复。在36个月时接受ASD诊断的婴儿中，固定持续时间最短。虽然这些研究结果表明，早期发展的精细措施的注意力部署早期ASD的病因，这些影响的特异性ASD仍有待确定。
Little is known about how spontaneous attentional deployment differs on a millisecond-level scale in the early development of autism spectrum disorders (ASD). We measured fine-grained eye movement patterns in 6-to 9-month-old infants at high or low familial risk (HR/LR) of ASD while they viewed static images. We observed shorter fixation durations (i.e. the time interval between saccades) in HR than LR infants. Preliminary analyses indicate that these results were replicated in a second cohort of infants. Fixation durations were shortest in those infants who went on to receive an ASD diagnosis at 36 months. While these findings demonstrate early-developing atypicality in fine-grained measures of attentional deployment early in the etiology of ASD, the specificity of these effects to ASD remains to be determined.
