Forty-one high-risk infants (HR) with an older sibling with autism spectrum disorder (ASD) were observed longitudinally at 10, 12, 18 and 24 months of age during a tool use task in a play-like scenario. Changes in grasp types and functional actions produced with a spoon were assessed during elicited tool use. Outcome and vocabulary measures were available at 36 months, distinguishing: 11 HR-ASD, 15 HR-language delay and 15 HR-no delay. Fewer HR-ASD infants produced grasp types facilitating spoon use at 24 months and functional actions at 10 months than HR-no delay. Production of functional actions in HR infants at 10 months predicted word comprehension at 12 months and word production at 24 and 36 months.
41 名具有自闭症谱系障碍(ASD)高风险的婴儿(HR)的兄弟姐妹进行了纵向观察,在类似游戏的场景中,他们在 10、12、18 和 24 个月大时进行了工具使用任务。在诱发的工具使用过程中,评估了使用勺子时抓握类型和功能动作的变化。在 36 个月时可以获得结果和词汇测量值,将其分为:11 名 HR-ASD、15 名 HR-语言延迟和 15 名 HR-无延迟。与 HR-无延迟的婴儿相比,24 个月时较少的 HR-ASD 婴儿产生了有利于勺子使用的抓握类型,10 个月时产生了功能动作。10 个月时 HR 婴儿的功能动作产生预测了 12 个月时的单词理解能力,以及 24 和 36 个月时的单词产生能力。
