Findings suggest that infant temperament affects the manner in which security or insecurity is expressed, but does not determine whether an infant develops a secure or insecure attachment to parent. (PCB)

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)

Relationship between maternal ratings of temperament and operant learning was examined in 18 2- to 3-month-old infants. Subjects participated in a conjugate reinforcement experiment; mothers of subjects completed the Carey and McDevitt Revised Infant Temperament Questionnaire 2 to 3 days before the learning study. Two temperament dimensions,…

Examines the hypothesis that degree of match or congruence between behavioral characteristics of infants and their families may significantly influence the nature of their interactions and the success of their mutual adaptation. Conducted a cross-sectional study on infant-family congruence on the degree of rhythmicity (predictable regularity in…

In the studies, subjects from different age groups (5-6, 7-8, 9-10, 18-22 years) observed vignettes designed to reveal an actor's abilities or personality traits, and were told about one instance of an actor's behavior, respectively. The subjects were then asked to predict the actor's behavior in related situations. Results focused differences in…

Activity of 50 children whose motility had been monitored by an electronic activity monitor when they were neonates was again monitored by an ambulatory microcomputer when they were four to eight years old. Results are consistent with evidence from several longitudinal studies suggesting that individual activity characteristics tend to persist…

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…

Investigated whether, in a sample of 30 infants, anger could reliably be observed in facial expressions as early as seven months of age. Also considered was the influence of several variables on anger responses: infants' familiarity with the frustrator, repetition of trials, and sex of the child. (Author/RH)

Seventh-grade children participated under two successive incentive conditions (self-prize and other prize) in a study of transgression behavior in a temptation task in which children were alternately offered a self-gratifying and an altruisitic incentive for successful performance. Most subjects behaved consistently across the incentive…

A total 72 children of 3 1/2, 5 1/2, and 7 1/2 years were asked questions about their behaviors and internal states, and of a best friend and an acquaintance. Results indicated even young children have concepts of themselves and other persons that are not restricted to specific points in time and may form basis for later dispositional conceptions.…

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…

Reveals that during the elementary school years, children acquire a firm understanding of the brain as the primary locus of psychological attributes and identity. The early school years, when children are five to seven years old, appear to be a transitional phase, when performance is variable and subject to task conditions. (RH)

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…

Type A behaviors were observed in a group of 48 preschool children in different free-play and competitive situations. Results are consistent with other findings on type A behavior in preschool children and suggest that the behavioral dimensions of type A (competitiveness and impatience-aggression) may emerge as early as the preschool years,…
