An empirical model of temperament that assessed transactional and cascade associations between respiratory sinus arrhythmia (RSA), negative affectivity, and the caregiving environment (i.e., maternal intrusiveness) across three time points during infancy (N = 388) was examined. Negative affectivity at 5 months was associated positively with maternal intrusiveness at 10 months, which in turn predicted increased negative affectivity at 24 months. RSA at 5 months was associated positively with negative affectivity at 10 months, which subsequently predicted greater RSA at 24 months. Finally, greater RSA at 5 months predicted greater negative affectivity at 10 months, which in turn predicted greater maternal intrusiveness at 24 months. Results are discussed from a biopsychosocial perspective of development.
一个评估婴儿期三个时间点（N=388）呼吸窦性心律失常（RSA）、负性情感和养育环境（即母亲侵入性）之间的交易和级联关联的气质经验模型被检验。5 个月时的负性情感与 10 个月时的母亲侵入性呈正相关，而母亲侵入性反过来又预测了 24 个月时的负性情感增加。5 个月时的 RSA 与 10 个月时的负性情感呈正相关，随后预测了 24 个月时更大的 RSA。最后，5 个月时更大的 RSA 预测了 10 个月时更大的负性情感，而这反过来又预测了 24 个月时更大的母亲侵入性。从发展的生物心理社会观点讨论了结果。
