本研究探讨了自发社会注意的潜在结构在11- 26个月大的自闭症谱系障碍（ASD，n = 90）和典型的发展（n = 79）控制。联合和个人方差解释的分解技术的应用表明，注意力是由一个条件独立的调整到动态的社会场景结构和上下文特定的结构捕捉选择的最相关的社会功能的处理。ASD中的凝视行为的特征在于对社交场景的有限调谐和选择非典型目标进行处理。虽然前者可能是由于奖励电路的早期中断，导致有限的升值的行为相关的社会信息，后者可能代表继发性赤字反映有限的知识，社会合作伙伴。
This study examined the latent structure of spontaneous social attention in 11- to 26-month-olds with autism spectrum disorder (ASD, n = 90) and typically developing (n = 79) controls. Application of the joint and individual variance explained decomposition technique revealed that attention was driven by a condition-independent tuning into the dynamic social scenes construct and context-specific constructs capturing selection of the most relevant social features for processing. Gaze behavior in ASD is characterized by a limited tuning into the social scenes and by a selection of atypical targets for processing. While the former may be due to early disruption of the reward circuitry leading to limited appreciation of the behavioral relevance of social information, the latter may represent secondary deficits reflecting limited knowledge about social partners.
