Object sharing abilities of infants at risk for autism (AR infants) and typically developing (TD) infants were compared from 9 to 15 months of age. Specifically, we examined the effects of infants' locomotor abilities on their object sharing skills. 16 TD infants and 16 AR infants were observed during an "object sharing" paradigm at crawling and walking ages. Overall, AR walking infants demonstrated lower rates of object sharing with caregivers compared to TD walking infants. Specifically, AR walking infants had lower rates of giving and approaches toward caregivers compared to TD walking infants. AR walking infants also had lower step rates toward task-appropriate targets, i.e. caregivers and objects compared to TD walking infants. No group differences in object sharing were observed at crawling ages. Object sharing could be a valuable context for early identification of delays in infants at risk for developing Autism spectrum disorder.
对自闭症风险婴儿（AR婴儿）和正常发育婴儿（TD婴儿）9至15个月大时的物品分享能力进行了比较。具体而言，我们研究了婴儿运动能力对其物品分享技能的影响。在“物品分享”范式中，对16名TD婴儿和16名AR婴儿在爬行和行走年龄段进行了观察。总体而言，与TD学步婴儿相比，AR学步婴儿与照顾者分享物品的比例较低。具体来说，与TD学步婴儿相比，AR学步婴儿向照顾者给予物品和靠近照顾者的比例较低。与TD学步婴儿相比，AR学步婴儿朝着任务相关目标（即照顾者和物品）的步频也较低。在爬行年龄段未观察到两组在物品分享方面的差异。物品分享可能是早期识别有患自闭症谱系障碍风险婴儿发育迟缓的一个有价值的情境。
