Mediated paths to over-reactive discipline: mothers' experienced emotion, appraisals, and physiological responses.

The present investigation was designed to evaluate whether mothers' emotion experience, autonomic reactivity, and negatively biased appraisals of their toddlers' behavior and toddlers' rates of misbehavior predicted over-reactive discipline in a mediated fashion. Ninety-three community mother-toddler dyads were observed in a laboratory interaction, after which mothers' emotion experience and appraisals of their toddler's behavior were measured via a video-recall procedure. Autonomic physiology and over-reactive discipline were measured during the interactions. Mothers' negatively biased appraisals mediated the relation between emotion experience and over-reactive discipline. Heart rate reactivity predicted discipline independent of this mediation. Toddler misbehavior appeared to be an entry point into the above process. Interventions that more actively target physiological and experiential components of mothers' emotion may further reduce their over-reactive discipline. ((c) 2005 APA, all rights reserved).
