The effects of the Healthy Steps for Young Children Program: results from observations of parenting and child development

The Healthy Steps for Young Children Program (HS) is designed to provide support for new parents through the pediatrician's office. We present findings of the effect of HS on the quality of mother–child interaction, security of attachment, and child behavior using observational data from two of the HS sites that utilized a randomized treatment design. Results indicated that mothers participating in Healthy Steps were more likely to interact sensitively and appropriately than mothers in the comparison group at the second assessment point (age 34–37 months) but not at the first assessment point (age 16–18 months). There were no differences in child outcomes at either time point when the cross-sectional data were analyzed. However, the results of the longitudinal analysis (which included families who participated in the home observations at both Time 1 and Time 2) indicated that Healthy Steps participation was associated with greater security of attachment and fewer child behavior problems.     

Relationship of Physique and Developmental Level to Physical Performance

Abstract

A study was made of the relationship of physique and developmental level, determined by use of the Wetzel Grid, to performance of junior high boys on four fitness tests: pull-ups, 50-yd. dash, standing broad jump, and softball throw. Subjects of different physique groups (heavy, medium, and thin) who were alike developmentally (accelerated, normal, and retarded) differed more markedly in performance than did subjects of different developmental levels who were alike with regard to physique. Subjects who were medium in physique and normal in development were the best performers. Subjects of heavy physique (many overweight) were the poorest performers. This would seem to indicate the need for a restudy of classification methods, particularly when norms are to be used for evaluating performance.     

The Relations of Parental Characteristics and Practices to Children''s Vicarious Emotional Responding

We examined the relation of parental empathy-related characteristics and emotion-related child-rearing practices to third and sixth graders' vicarious emotional responding. Children's heart rate, skin conductance, facial, and self-reported reactions to a sympathy-inducing film were assessed, as were their dispositional sympathy, empathy, and self-monitoring. Parental sympathy was positively related to low levels of personal distress in same-sex children and, for both parents, with sons' dispositional sympathy or empathy. Parental emphasis on problem-focused coping strategies when their sons were anxious was positively correlated with indexes of sons' situational and dispositional sympathy. Same-sex parental restrictiveness in regard to the control of inappropriate, hurtful emotional displays was associated with sons' and daughters' dispositional and situational sympathy, whereas maternal restrictiveness in regard to emotions that are unlikely to hurt others was correlated with nonverbal indexes of personal distress and self reports of low distress. Parental emphasis on control of the child's own negative emotion was associated with children's self-monitoring.     

Spacing extinction trials alleviates renewal and spontaneous recovery

Studies of extinction in classical conditioning situations can reveal techniques that maximize the effectiveness of exposure-based behavior therapies. In three experiments, we investigated the effect of varying the intertrial interval during an extinction treatment in a fear-conditioning preparation with rats as subjects. In Experiment 1, we found less fear at test (i.e., more effective extinction) when extinction trials were widely spaced, relative to intermediate or massed extinction trials. In Experiment 2, we used an ABA renewal procedure and observed that spaced trials attenuated renewal of conditioned fear relative to massed trials. In Experiment 3, we used a similar design, but instead of changing the physical context at the time of testing, we interposed a retention interval after the extinction treatment to produce a change in the temporal context. The results showed less spontaneous recovery of fear after spaced than after massed extinction trials. These results suggest that extinction is more enduring when the extinction trials are spaced rather than massed. Although the benefits of spacing trials are small when there is no contextual change from extinction to testing, a change in either physical or temporal context following massed extinction trials leads to a recovery from extinction, which is reduced when the trials are spaced.
