Infants at elevated likelihood of developing autism display differences in sensory reactivity, especially hyporeactivity, as early as 7 months of age, potentially contributing to a developmental cascade of autism symptoms. Caregiver responsiveness, which has been linked to positive social communication outcomes, has not been adequately examined with regard to infant sensory reactivity. This study examined the multiplicative impact of infant sensory hypo- and hyperreactivity on caregiver responsiveness to sensory reactivity and regulation cues in 43 infants at elevated likelihood of autism. Sensory hyperreactivity was found to moderate the association between sensory hyporeactivity and caregiver responsiveness, such that caregivers of infants with moderately high sensory hypo- and hyperreactivity demonstrated higher responsiveness.
高风险自闭症婴儿早在 7 个月大时就表现出感觉反应差异，尤其是低反应性，这可能导致自闭症症状的发展级联。与积极的社会沟通结果相关的照顾者反应性，尚未充分研究其与婴儿感觉反应性的关系。本研究在 43 名高自闭症风险婴儿中，检查了婴儿感觉低反应性和高反应性对照顾者对感觉反应和调节线索的反应性的相乘影响。研究发现，感觉高反应性调节了感觉低反应性与照顾者反应性之间的关系，以至于具有中度高感觉低和高反应性的婴儿的照顾者表现出更高的反应性。
