Examined associations between the activity level and adaptability of same-sex siblings and qualitative aspects of their relationship. Found high levels of conflict when both siblings were high in activity and the older sibling was rated more active than the younger. Conflict was lowest when siblings were low in activity. Warmth was greatest when…

Investigated the usefulness of Carey's Revised Infant Temperament Questionnaire in the Chinese culture and used the questionnaire to assess the temperamental characteristics of Chinese babies. While the general pattern of results resembled data from Carey's American sample, differences were found, which could be interpreted in terms of response…

Examined the reactions of 201 elementary school children to direct and indirect help and the moderating effects of grade, understanding of personality, and sex on children's reaction to aid. Results indicated that children high in the understanding of consistency of personality were more autonomous in the indirect than the direct help condition.…

Investigated relationships between mothers' perception of infants temperament at 6 months and their behavior toward their infants at 6 and 12 months of age among 40 firstborn Israeli infants. Temperamental intensity ratings were related to auditory stimulation and contingent positive vocalization for girls and to increased physical contact for…

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.…

A total of 114 boys and girls were given an expectancy that a stimulus child was either shy or outgoing and then rated the child on several personality dimensions. Results revealed that, when children were presented with both expectancy-congruent and expectancy-incongruent information, impression formation was largely attribute based, and the…

Tested for bias toward shifting attention toward threatening stimuli among high-anxious children and away from such stimuli among low-anxious children, ages 11-14. Results supported the predicted attentional bias toward threat cues among high-test-anxious children. Unexpectedly, the predicted attentional bias away from threat cues among…

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)

Relations among hormone levels, emotional dispositions, and aggressive attributes were examined in 56 boys and 52 girls, aged 9 to 14 years. (PCB)

Attempted to replicate findings of a previous study which found that mother-toddler interaction during problem solving was related to the child's prior attachment security. Examined the relationship between problem-solving interactions on the one hand, and mother-child interactions at home and infant temperament on the other. (PCB)

Developmental change in self-esteem was assessed from early adolescence through early adulthood. Found that males tended to increase and females to decrease in self-esteem over time and that there was rank order consistency in self-esteem over time. Within each gender, individuals' differences in developmental trajectories were related to…

Examined factors associated with young children's aggression. Observed 104 toddlers during free play with same-sex peer, with both mothers present. Found that early out-of-home care was not related to aggression. Boys were more aggressive than girls. Observed aggression and mother-reported externalizing problems were associated significantly with…

Outline faces were presented for rating along six dichotomous attributes with features varying systematically. Differences were found to be largely attentional, with certain features invariably being differentially employed and associated with certain attributes across all samples. (WY)

Using extensive, multifaceted observational and interview data from the Family Socialization and Developmental Competence Project (FSP), this paper examines the claims that androgynes, by comparison with sex-typed individuals, are more effective persons and parents. (Author/RH)

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)
