We investigated gesture production in infants at high and low risk for autism spectrum disorder (ASD) and caregiver responsiveness between 12 and 24 months of age and assessed the extent to which early gesture predicts later language and ASD outcomes. Participants included 55 high-risk infants, 21 of whom later met criteria for ASD, 34 low-risk infants, and their caregivers. Results indicated that (a) infants with ASD outcomes used fewer gestures and a lower proportion of developmentally advanced gesture-speech combinations; (b) caregivers of all the infants provided similar rates of contingent responses to their infants' gestures; and (c) gesture production at 12 months predicted subsequent receptive language and ASD outcomes within the high-risk group.
我们调查了高风险和低风险自闭症谱系障碍（ASD）婴儿在 12 至 24 个月大时的手势生成以及照顾者的反应能力，并评估了早期手势对后期语言和 ASD 结果的预测程度。参与者包括 55 名高风险婴儿，其中 21 名后来符合 ASD 标准，34 名低风险婴儿及其照顾者。结果表明：（a）具有 ASD 结果的婴儿使用的手势较少，且发展先进的手势-言语组合的比例较低；（b）所有婴儿的照顾者对手势的回应率相似；（c）12 个月大时的手势生成预测了高风险组后续的接受性语言和 ASD 结果。
