被诊断患有自闭症谱系障碍（ASD）的个体在视觉注意力的适应性分配方面表现出终身异常。ASD中注意力障碍的普遍存在性导致一些作者假设非典型注意力调节可能是更高级别社交缺陷发展的一个因素。参与者是20名ASD儿童和20名年龄和非言语智商匹配的典型发育（TD）儿童。我们使用注意力网络测试（ANT）调查三个离散的注意力网络的效率和独立性：警觉，定向和执行控制。此外，我们试图调查每一个注意力网络和社会交往症状严重程度的措施与ASD儿童之间的关系。结果表明，自闭症儿童的定向，但不是警觉或执行控制，网络可能会受损。与TD儿童相反，相关性分析表明，ASD儿童的警觉和执行控制网络可能不独立运作。此外，在ASD儿童中，发现警报网络和社会障碍之间以及执行控制网络和智商之间存在关联。研究结果提供了进一步的证据，在ASD的视觉空间定向网络的损害，并建议，可能有更大的相互依赖的警觉和执行控制网络在ASD。此外，有效调节警觉性水平的能力下降与社会交际缺陷增加有关，这表明域一般注意力功能可能与ASD认知功能相关。
Individuals diagnosed with autism spectrum disorder (ASD) exhibit lifelong abnormalities in the adaptive allocation of visual attention. The ubiquitous nature of attentional impairments in ASD has led some authors to hypothesize that atypical attentional modulation may be a factor in the development of higher-level sociocommunicative deficits. Participants were 20 children with ASD and 20 age- and Nonverbal IQ-matched typically developing (TD) children. We used the Attention Network Test (ANT) to investigate the efficiency and independence of three discrete attentional networks: alerting, orienting, and executive control. Additionally, we sought to investigate the relationship between each attentional network and measures of sociocommunicative symptom severity in children with ASD. Results indicate that the orienting, but not alerting or executive control, networks may be impaired in children with ASD. In contrast to TD children, correlational analyses suggest that the alerting and executive control networks may not function as independently in children with ASD. Additionally, an association was found between the alerting network and social impairment and between the executive control network and IQ in children with ASD. The results provide further evidence of an impairment in the visuospatial orienting network in ASD and suggest that there may be greater interdependence of alerting and executive control networks in ASD. Furthermore, decreased ability to efficiently modulate levels of alertness was related to increased sociocommunicative deficits, suggesting that domain-general attentional function may be associated with ASD symptomatology.
