To better understand quantity and quality of divorced father contact, a weighted county sample of 230 divorced fathers with a child aged 4-11 years was employed to test whether fathers' antisocial personality (ASP) moderated effects of monthly contact with children in predicting children's observed noncompliance. Eighteen-month latent growth…

A total of 114 infants at three age levels (11, 18, and 28 weeks) were rated by their mothers on a termperament questionnaire and subjected to a habituation procedure. Results suggest that subject loss in habituation studies may be the result of nonrandom individual difference factors and not just the result of temporary fluctuations in state.…

Results suggest that various aspects of Strange Situation behavior are related to both maternal and infant temperament, and that maternal temperament is a predictor of attachment security, particularly for Type A mother-avoidant infants. (Author/RH)

Factor scores from Bayley's Infant Behavior Record (obtained from 300 to 400 infants at six, 12, 18, and 24 months) were selected to represent three aspects of infant behavior: task orientation, test affect-extraversion, and activity. Findings indicate reordering of individual differences is age-related and that the reordering sequence is somewhat…

Explored relation between temperament and cardiac vagal tone in 12-week olds. Found that infants with higher baseline vagal tone showed fewer negative behaviors in the laboratory and were less disrupted by experimental procedures than infants with lower baselines. Infants who decreased cardiac vagal tone during assessments were rated by mothers as…

Investigated continuities in mother-infant interaction observed at home, maternally perceived infant difficulties, and infant developmental competency. Also assessed were background characteristics and possible variables moderating maternal report of satisfaction with adjustment. A total of 128 dyads were assessed when infants were 6 and 13 months…

Explored the roles of genes and environment in masculinity and femininity during pre- and early adolescence in 70 twins of 8-14 years. Results revealed significant genetic influences in all measures. Environmental influences were specific to each individual and not shared by members of the same twin pair. (RJC)

Examined (1) the possibility that children organize general statements into meaningful and consistent psychological concepts of themselves; (2) individual differences revealed in these concepts; (3) the possibility that these differences show stability over a one-month period. (PCB)

Findings indicated a significant interaction between activity level and intensity of stimulation in predicting exploratory competence and total exploration among 52 toddlers of 15 months of age who were observed in their homes 6 times over a 4-week period. (RH)

Assessments of temperament, emotion, cognition, and language acquisition were obtained for 200 pairs of 14-month-old twins. Comparisons between the assessment correlations for identical and fraternal twins indicated an influence of genetics on inhibition, activity, temperament, empathy, negative emotion, spatial memory, categorization skills, and…

Examined 8- to 10-month-olds' responses to standard procedures eliciting joy, fear, anger, and discomfort. Found that response parameters to standard procedures cohered strongly within each episode. Responses cohered across same-emotion episodes, except for anger. Responses and father-reported temperament related to infant's emotional tone in…

Investigated sex differences in the motor activity level of 83 children of 5-8 years. Relative maturity was negatively related to activity level. Girls were less motorically active and more mature than boys. (RJC)

Describes the development of a parent-report to assess infant temperament and presents longitudinal findings. Scales were developed to measure activity level, soothability, fear, distress to limitations, smiling/laughter, and duration of orienting. Longitudinal analyses showed that stability in some scales was age-related. (Author/DB)

Convergence between temperament ratings from two different sources (mothers and observers) and observer codings of peer-peer interaction was assessed. (Author/MP)

Examined whether children who vary in their behavioral responses to ambiguous provocation but have similar attributional processes differ in their social goals and self- efficacy perceptions. Subjects were 781 4th and 5th graders. Found that aggressive, withdrawn, and problem-solving responders differed in the social goals and self-efficacy…
