In this article, we contrast evolutionary and psychobiological models of individual development to address the idea that individual development occurring in prototypically risky and unsupportive environments can be understood as adaptation. We question traditional evolutionary explanations of individual development, calling on the principle of…

This study provides additional data on the measurement of children's and adolescents' appraisals of interparental conflict using the Children's Perception of Interparental Conflict (CPIC) Scale (Grych, Seid, & Fincham, 1992). Data from the original sample of early adolescents (N = 222) on which the CPIC Scale was developed and the authors' own…

The study of social dominance has a long tradition within the peer relationships literature, but rarely has the topic been investigated observationally and longitudinally within other salient close relationships. The present study investigated the role of experiences in social relationships and adjustment indices in childhood in predicting later…

The relations of children's (n=214 at Time 1; M age=6 years at Time 1) dispositional sympathy to adult-reported and behavioral measures of effortful control (EC) and impulsivity were examined in a longitudinal study including five assessments, each two years apart. Especially for boys, relatively high levels of EC and growth in EC were related to…

The present study examined the startle reflex as a physiological marker of behavioral inhibition. Participants were 7 to 12-year-old children who had been previously identified as inhibited or uninhibited as part of an ongoing longitudinal study on the role of behavioral inhibition in the development of anxiety disorders. Analysis of their scores…

Studies the aggressiveness of over 600 subjects, their parents, and their children over a 22-year period. Subjects who were more aggressive 8-year-olds were more aggressive 30-year-olds, exhibiting serious antisocial behavior as adults. The stability of aggression across generations within a family was also high. (Author/CB)

This article describes the average and group-based developmental trajectories of aggression, opposition, property violations, and status violations using parent reports of externalizing behaviors on a longitudinal multiple birth cohort study of 2,076 children aged 4 to 18 years. Trajectories were estimated from multilevel growth curve analyses and…

In a study of operative thought in children, 104 children, aged 4 to 9, were tested 5 times with the same 25 Piagetian tasks. There were manifest indicators of synergy in the development of the various behaviors, but it was not possible to validate specific problems of behavior organization. (SLD)

Hyperactive children appear to be at an increased risk for antisocial behavior in life. Follow-up studies using self-report and official criminal data have found that hyperactive children are more likely than controls to commit crimes, to be arrested for crimes, to be convicted of crimes, and to be diagnosed with Antisocial Personality Disorder in…

Reported was an 8 year longitudinal study of social and antisocial behavioral correlates in 1550 third, sixth, and ninth grade children identified as either aggressive-disruptive or prosocial by their teachers. A more intensive study was made of 192 aggressive-disruptive and 192 prosocial children. Data included interviews, individual tests (such…

This study addresses the utility of the resilient, overcontrolled, and undercontrolled personality prototypes for predicting children's and adolescents' problem behaviour in a longitudinal general population sample (N = 491). Both parents and one child participated in the study at two measurement occasions separated by a 3-year interval. The major…

This six-culture study sought to make a first approximation measurement of differences in personality development and the socialization of these differences in children. The study was part of a larger strategy involving other cultures and methods. A sample of 24 children from each of the six cultures was selected and observed during at least 12…

The Cross-National Study of Coping Styles and Achievement was designed to develop a conceptual system for describing effective coping behavior in several cultures; to develop measures of coping style and coping effectiveness which would be uniformly applicable in the various cultures; and to determine the relationship of such coping behavior to…

Examined the role of difficult temperament or behavioral style and tobacco, alcohol, and marijuana use in the 133 subjects of the New York Longitudinal Study. Results indicated that the possession of difficult temperamental characteristics at age five and in early adulthood are associated with drug use in young adulthood. (JAC)

Intervention programs which take a family perspective and treat families as a unit have a greater positive impact than programs which focus on the child alone. Yet, despite the emphasis on parental involvement, very little attention is given to parents' perceptions of their child's treatment. This study explored parents' ratings of treatment and…
