本研究通过Etch-A-Sketch画板任务，收集了150个7到12岁的儿童与其父亲或母亲在互动过程中的心跳间期（IBI）序列数据，将双方IBI序列的互相关系数作为亲子生理同步性的指标，使用成型的量表对父母在互动中表现的心理不及性以及儿童的自我管理进行打分，同时通过心理控制量表获得由儿童报告的父母心理控制。本研究发现，生理同步性与儿童行为上的自我管理有关，父亲或母亲的心理不及性可以预测亲自生理同步性，并进而影响儿童行为上的自我管理，这一结果说明了生理同步性在童年中期的作用和父母教养方式带来的影响。

Using Etch-A-Sketch interaction task, the present study recorded interbeat interval (IBI) data of 150 parent-child dyads. The children were of school age (7-12). The cross correlation functions of IBI series of each member in a dyad was used as indicator of physiological synchrony. The dyadic interaction was videotaped and rated on parental psychological unavailability and child self-regulation using a established system. Parent psychological control was reported by children using PPSY/MPSY. The present study proved positive association between physiological synchrony and child self-regulation on behaviors. Sensitive parenting has a positive effect on physiological synchrony and can further influence self-regulation. The results suggested how physiological synchrony functions in middle childhood, and uncovered effects of parenting.
