这项横断面研究旨在（a）描述对社会和非社会刺激的感觉低反应性的发展相关性，（B）确定相对于对照组，自闭症儿童的低反应性是否在不同背景下普遍存在，（c）测试低反应性和社会沟通结果之间的关联。三组儿童年龄11-105个月（N = 178;自闭症= 63，发育迟缓= 47，典型发展= 68）给予发展和感官措施，包括行为定向任务（感官处理评估）。实验室测量结果与父母报告的感觉低反应性显著相关。删失回归模型显示，随着心理年龄（MA）的增加，低反应性在各组中降低。群体差异是显着的，但取决于双向互动与MA和上下文（社会和非社会）。在一个非常年轻的MA（例如，6个月），自闭症组比发育迟缓和典型发育组对社会和非社会刺激表现出更多的低反应性（对社会的影响更大），但在年龄较大的MA（例如，60个月）没有显着差异。对社会和非社会刺激的低反应性预示着自闭症儿童的联合注意力和语言水平较低。注意力脱离和行为定向的一般化过程可能与识别自闭症的早期风险因素以及促进跨环境学习以支持联合注意力和语言的发展有关。
This cross-sectional study seeks to (a) describe developmental correlates of sensory hyporesponsiveness to social and nonsocial stimuli, (b) determine whether hyporesponsiveness is generalized across contexts in children with autism relative to controls, and (c) test the associations between hyporesponsiveness and social communication outcomes. Three groups of children ages 11–105 months (N = 178; autism = 63, developmental delay = 47, typical development = 68) are given developmental and sensory measures including a behavioral orienting task (the Sensory Processing Assessment). Lab measures are significantly correlated with parental reports of sensory hyporesponsiveness. Censored regression models show that hyporesponsiveness decreased across groups with increasing mental age (MA). Group differences are significant but depend upon two-way interactions with MA and context (social and nonsocial). At a very young MA (e.g., 6 months), the autism group demonstrates more hyporesponsiveness to social and nonsocial stimuli (with larger effects for social) than developmental delay and typically developing groups, but at an older MA (e.g., 60 months) there are no significant differences. Hyporesponsiveness to social and nonsocial stimuli predicts lower levels of joint attention and language in children with autism. Generalized processes in attention disengagement and behavioral orienting may have relevance for identifying early risk factors of autism and for facilitating learning across contexts to support the development of joint attention and language.
