Findings from previous cross-sectional studies showed that while toddlers around their first birthday imitate selectively, that is, they systematically omit some kinds of target action steps or they copy only the goal, but not the means of the modeled actions, older toddlers imitate more exactly. The aim of the present article is to provide…

In the present investigation, we studied the development of 6 physically aggressive behaviors in infancy and toddlerhood, posing 3 questions (a) How do the prevalences of individual physically aggressive behaviors change from 8, 15, and 24 months? (b) Are there groups of children who show distinctive patterns in the way individual physically…

Premature infants have significant risk for later behavior problems. This study examined growth trajectories of three problem behaviors across five developmental age points from preschool to early adulthood in a well-characterized sample of premature infants. The effects of neonatal risk, gender, and socioeconomic context were modeled on these…

Although tattling is a common practice among young children, there is little systematic research about its socioemotional correlates. The current study focused on children's tattling between the ages of 5 and 7, assessing both their explicit attitudes toward tattling and their actual reporting of a transgression and relating them to individual…

The current study examined the stability of temperament over time. Observers and mothers rated child behavior at eight timepoints across three assessment waves (8, 15, and 30 months of age). Internal consistency reliability of aggregates of the eight observer reports and eight mother reports were high. When considering single timepoint…

The aim of the study was to examine differences in children's generalised trust and the maternal behaviour, child temperament, and demographic factors on the levels of trust in children. A total of 314 mothers and their children participated in the study. Results showed no evidence of sex differences in children's beliefs. Children living in urban…

Temperament is important for considering differences among diagnostic groups and for understanding individual differences that predict problematic behavior. Temperament characteristics, such as negative affectivity, effortful control, and surgency (highly active and impulsive), are predictive of externalizing behavior in typically developing…

Examined early development of guilt in 106 children observed in laboratory paradigms in which they were led to believe they had damaged valuable objects during 2 sessions at 22, 33, and 45 months. Found support for a mediational model in which fearful temperament contributed to guilt proneness, which served to inhibit children's tendency to…

Examined differences in attraction to same- and other-sex peers as a function of sex, age, individual characteristics, and context in adolescents studied longitudinally from elementary to middle school. Found attraction to aggressive peers and to peers standing out in observable ways increased with age and upon entry to middle school, whereas…

Maintains that adaptive help seeking exemplifies how elementary- and middle-school students regulate their own learning and intellectual development. Discusses how parents, teachers, and peers contribute to the development of children's skills and attitudes associated with adaptive help seeking. Traces early help-seeking behaviors in the home and…
