我们调查了与低风险对照组相比，在自闭症儿童的兄弟姐妹中，社会凝视和情感以及联合注意行为的缺陷是否在第一年内明显，这些兄弟姐妹继续被诊断为自闭症或ASD（ASD）和未被诊断的兄弟姐妹（NoASD-sib）。在6个月大时，ASD组与其他两组在凝视、微笑和发声的频率方面没有差异，也没有对她退出互动的敏感性。然而，到12个月时，ASD组的婴儿表现出较低的联合注意力和要求行为的比率。相比之下，NoASD同胞在6个月和12个月时与对照婴儿在任何感兴趣的变量上没有差异。
We investigated whether deficits in social gaze and affect and in joint attention behaviors are evident within the first year of life among siblings of children with autism who go on to be diagnosed with autism or ASD (ASD) and siblings who are non-diagnosed (NoASD-sib) compared to low-risk controls. The ASD group did not differ from the other two groups at 6 months of age in the frequency of gaze, smiles, and vocalizations directed toward the caregiver, nor in their sensitivity to her withdrawal from interaction. However, by 12 months, infants in the ASD group exhibited lower rates of joint attention and requesting behaviors. In contrast, NoASD-sibs did not differ from comparison infants on any variables of interest at 6 and 12 months.
