心率和心率变异性的心理生理学研究可以用来研究自闭症儿童的调节过程。本研究的目的是测试呼吸性窦性心律失常（RSA;心率变异性的测量）的差异，并检查生理反应和社会行为的测量之间的关系。参与者包括2至6岁的自闭症儿童和非自闭症儿童。心率和RSA来自基线期间的ECG记录，然后是陌生人方法范例。社交和适应行为由父母报告评估。在基线或对社会挑战的反应中，各组的平均心率或RSA没有差异。然而，自闭症儿童更可能对陌生人方法的侵入性部分表现出生理反应，而不是对该程序的侵入性较低的部分。非自闭症儿童同样可能对侵入性和侵入性较小的社会事件做出反应。在自闭症组中，对陌生人侵入的生理反应对应于更高的社会适应行为评分。这些结果表明，对社会挑战的生理反应可能有助于理解自闭症儿童社会行为结果的差异。
Psychophysiology studies of heart rate and heart rate variability can be employed to study regulatory processes in children with autism. The objective of this study was to test for differences in respiratory sinus arrhythmia (RSA; a measure of heart rate variability) and to examine the relationship between physiologic responses and measures of social behavior. Participants included 2‐ to 6‐year‐old children with Autistic Disorder and children without autism. Heart rate and RSA were derived from ECG recordings made during a baseline period and then a stranger approach paradigm. Social and adaptive behavior was assessed by parent report. Groups did not differ in mean heart rate or RSA at baseline or in response to social challenge. However, children with autism were more likely to show a physiologic response to intrusive portions of the stranger approach than to less intrusive portions of this procedure. Nonautistic children were equally likely to respond to intrusive and less intrusive social events. Within the autistic group, physiologic response to the intrusive stranger approach corresponded to higher ratings of social adaptive behaviors. These results suggest that physiologic responses to social challenge may help understand differences in social behavioral outcomes in children with autism.
