Few studies have examined whether familiarity of partner affects social responses in children with autism. This study investigated heart rate regulation (respiratory sinus arrhythmia [RSA]: The myelinated vagus nerve's regulation of heart rate) and temporal-parietal electroencephalogram (EEG) activity while nineteen 8- to 12-year-old children with autism and 14 controls viewed videos of a familiar and an unfamiliar person reading a story. Children with autism had lower overall RSA levels and exhibited decreased RSA to the unfamiliar person, versus control children. Both groups decreased temporal-parietal EEG activity to the unfamiliar person. Higher RSA was related to higher social skill ratings and fewer problem behaviors. Thus, the social difficulties of children with autism may be characterized by specific mobilization to unfamiliar people.
很少有研究探讨伙伴的熟悉程度是否会影响自闭症儿童的社交反应。本研究调查了19名8至12岁自闭症儿童和14名对照组儿童在观看熟悉和不熟悉的人读故事的视频时的心率调节（呼吸性窦性心律不齐[RSA]：有髓迷走神经对心率的调节）以及颞顶叶脑电图（EEG）活动。与对照组儿童相比，自闭症儿童的整体RSA水平较低，且对不熟悉的人表现出RSA降低。两组对不熟悉的人都降低了颞顶叶EEG活动。较高的RSA与较高的社交技能评分和较少的问题行为相关。因此，自闭症儿童的社交困难可能表现为对不熟悉的人有特定的反应。
