我们比较了自闭症谱系障碍儿童（兄弟姐妹- asd， n = 25）和正常发育儿童（兄弟姐妹- td， n = 30）在6.5个月和9个月大时的工作记忆（WM）对社会目标和非社会目标定位的影响。风险组和目标类型在WM上存在显著的相互作用，其中兄弟- asd在非社会目标上的WM优于对照组。两项非记忆测试均无刺激相互作用组。结果表明，在9个月大时，asd兄弟姐妹在非社会刺激的WM（创造、更新和使用瞬态表征）能力上的提高将他们与td兄弟姐妹区别开。这种早期出现的力量被认为是一种发展途径，可能对ASD风险儿童的社会注意力和学习有影响。
We compared working memory (WM) for the location of social versus non-social targets in infant siblings of children with Autism Spectrum Disorders (sibs-ASD, n = 25) and of typically developing children (sibs-TD, n = 30) at 6.5 and 9 months of age. There was a significant interaction of risk group and target type on WM, in which the sibs-ASD had better WM for non-social targets as compared with controls. There was no group by stimulus interaction on two non-memory measures. The results suggest that the increased competency of sibs-ASD in WM (creating, updating and using transient representations) for non-social stimuli distinguishes them from sibs-TD by 9 months of age. This early emerging strength is discussed as a developmental pathway that may have implications for social attention and learning in children at risk for ASD.
