Abstract:Sixty-five mothers and their 24-month-old toddlers were observed in a series of laboratory procedures designed to assess relations between maternal interactive style and emotional, behavioral and physiological regulation. Emotional regulation was assessed by examining the child's behaviors (aggression, distraction, object focus) when confronted by three emotioneliciting tasks. Behavioral regulation was measured by examining children's ability to comply to maternal requests and to inhibit behavior during a delay task. Physiological regulation was derived from children's cardiac vagal tone responses to emotionally-arousing situations. Maternal interactive style was assessed by examining mothers' strategies for child behavior management (negative controlling, positive guidance) during three mother-child tasks. Maternal behavior was related to regulation in each of the three domains. Negative maternal behavior was related to poor physiological regulation, less adaptive emotion regulation, and noncompliant behavior. Positive maternal behavior was correlated with compliance, but not with any of the physiological or emotional measures. These findings are discussed in terms of the adaptive value of self-regulation in early development, and the importance of identifying the causal relations between maternal behavior and child regulation.

A study sample of 162 six‐month‐old children was selected from a larger sample of 346 infants on the basis of parents' report of their infants' temperament and a laboratory assessment of temperament. Infants were classified as easily frustrated and less easily frustrated and compared on a number of emotion regulation, physiology, and temperament measures. Results indicated that male and female infants were equally likely to be classified as frustrated and less easily frustrated; however, male infants were less able to regulate physiologically. Easily frustrated infants used different emotion regulation strategies and were observed to be less attentive and more active than less easily frustrated infants when observed in the laboratory. These infants were also characterized by their parents as more active, less attentive, and more distressed to novelty. Infants classified as easily frustrated were more reactive physiologically and less able to regulate physiological reactivity than their less easily frustrated counterparts. It is hypothesized that this cluster of characteristics may constitute a unique temperamental type that may have implications for other types of behavioral functioning. Limitations of the study are that observations are based on a single brief assessment of the infant, modest effect sizes were found, and the study is cross‐sectional.

Fifty-six mothers and their 24-month-old toddlers were observed on two occasions in a series of laboratory procedures designed to assess relations between emotional functioning (emotional reactivity and emotion regulation) in an individual assessment and social behavior with a same-sex peer. Emotional reactivity was assessed using two frustration tasks designed to elicit distress. Emotional regulation was assessed by examining the child's behaviors (venting, distraction, focal-object focus, self-orientation, and mother-orientation) when confronted by the two distress-eliciting tasks. Peer play behaviors were coded for social participation and peer-directed conflict (aggressive) behavior. The results indicated that both emotional reactivity and emotion regulation were important predictors of at least two types of social behavior: conflict and cooperation. Distress to frustration, when accompanied by high venting or high focal-object focus, was significantly related to conflict with peers but not when accompanied by distraction, mother-orientation or self-focused behaviors. These findings are discussed in terms of the adaptive value of emotion regulation skills in early development, and the importance of identifying the causal relations between child regulation and early social competence.

Ninety-nine 2-year-olds, out of a larger sample of 474 children, were classified as high (n = 49) or low (n = 50) in externalizing (aggressive/destructive) behaviors based on maternal reports assessed twice across a 2-month period. During a laboratory assessment, these toddlers participated in two empathy-eliciting tasks, from which affective, behavioral, and physiological measures were derived. Relations among measures of empathy were examined both within and across episodes and aggression groups. Analyses indicated that different indices of empathy were related to each other, both within and across empathy situations. In addition, aggressive children displayed more behaviors indicative of empathy than did nonaggressive children. Finally, a pattern of physiological responding to another's distress was evident across both groups of children, and some results indicated that greater physiological regulation was related to less empathy-related behavior. Results are discussed in terms of the developing nature of empathy and its changing association with both self-regulation and aggression.
