The hypothesis was tested that some children develop a defensive mindset that subsumes individual social information processing (SIP) steps, grows from early experiences, and guides long-term outcomes. In Study 1 (Fast Track [FT]), 463 age-5 children (45% girls; 43% Black) were first assessed in 1991 and followed through age 32 (83% retention). In…

This study examined whether changes in children's self-reported Big Five dimensions are represented by (developmental) personality types, using a cohort-sequential design with three measurement occasions across 5 years (four cohorts, 9-12 years at T1; N = 523). Correlates of, and gender differences in, type membership were examined. Latent…

The development of response inhibition was investigated using a computerized go/no-go task, in a lagged sequential design where 376 preschool children were assessed repeatedly between 3.0 and 5.25 years of age. Growth curve modeling was used to examine change in performance and predictors of individual differences. The most pronounced change was…

Two hypotheses--high self-esteem leads children to act on antisocial cognitions (disposition-activating hypothesis) and high self-esteem leads children to rationalize antisocial conduct (disposition-rationalizing hypothesis)--were investigated in two longitudinal studies. In Study 1 (N = 189; mean age = 11.1 years), antisocial behavior was…

Latent growth curve modeling employed data from a longitudinal study of 451 sibling families to examine parents, siblings, and family economics as factors in individual differences in the developmental course of interpersonal aggression during adolescence. Findings suggest that individual change in interpersonal aggression during adolescence can…

Examined longitudinally changes in inhibition from toddler age to age 4 and age 7 years. Found that temperament change in children who tested as inhibited or uninhibited as toddlers was more common than remaining extremely inhibited or uninhibited, but that change was largely limited to intermediate groups. Subgroups distinguished by responses on…

This longitudinal study investigated the validity of the Five Factor Model of personality with Swedish children ages 2 to 15 years. Findings of item analyses showed consistently reliable irritability, conscientiousness, and positive activity factors, while internal reliability of other factors increased over time. Found that irritability and…

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 the longitudinal predictability of spatial ability in late-adolescent females. No timing of puberty or lateralization effects were observed. These findings strengthen evidence that sex-related differences in spatial ability could be experientially determined and may help to focus the search for exactly how this occurs. (Author/GLR)

Observed 18- to 30-month-olds' use of force against peers. Found no sex differences in average aggression levels or in mothers' aggression ratings. Rate of hitting peers and mothers' ratings were stable over 6 months for girls only. Toddlers especially sensitive to peers' possible intentions hit peers more and were more likely than to use force…

Reports on a longitudinal study that provides a prospective view of children's personality functioning prior to their subsequent experiencing of divorce. Shows the behavior of boys as early as 11 years prior to parental separation or formal dissolution of marriage to be consistently affected by predivorce familial stress. (HOD)

Discusses results of a longitudinal study of effects of divorce and remarriage on children's adjustment. Results suggest that individual characteristics play an important role in either protecting children from negative consequences associated with their parents' marital transitions or in making children vulnerable to such consequences.
