对直接凝视和儿童导向语言的注意力的变化可能有助于自闭症谱系障碍(ASD)幼儿临床表现的异质性。为了评估这一假设,我们聚集了65个20个月大的ASD幼儿,根据他们对参与的二元线索的视觉反应,确定了三个亚组。随后,我们比较了这些亚组在3岁时的社会,语言和适应功能。集群显示有限的关注社会场景一般表现出不良的结果在3年;集群显示良好的关注现场和扬声器的嘴是口头和高功能在3年。对二元线索的视觉反应的分析可以提供一种临床上有意义的方法来识别结果的早期预测因子。
Variability in attention towards direct gaze and child-directed speech may contribute to heterogeneity of clinical presentation in toddlers with autism spectrum disorders (ASD). To evaluate this hypothesis, we clustered sixty-five 20-month-old toddlers with ASD based on their visual responses to dyadic cues for engagement, identifying three subgroups. Subsequently, we compared social, language, and adaptive functioning of these subgroups at 3 years of age. The cluster displaying limited attention to social scenes in general exhibited poor outcome at 3 years; the cluster displaying good attention to the scene and to the speaker's mouth were verbal and high functioning at 3 years. Analysis of visual responses to dyadic cues may provide a clinically meaningful approach to identifying early predictors of outcome.
