Developmental systems theory and life span development describe the role of individual--context interactions in individual development but have not directly addressed how individuals pursue achievement goals in institutional contexts. We developed a theory informed by these perspectives that explains how institutional contexts affect emerging…

This review challenges the traditional interpretation of infants' and young children's responses to three types of potentially "fear-inducing" stimuli--snakes and spiders, heights, and strangers. The traditional account is that these stimuli are the objects of infants' earliest developing fears. We present evidence against the…

The stability of callous-unemotional (CU) traits and both individual and contextual factors that influence this stability have been studied in community adolescent samples but not to great extent in adolescents who have been arrested. We estimated the developmental changes in CU traits measured over the course of 36 months (6-month intervals)…

Increasing age is characterized by greater positive affective states. However, there is mixed evidence on the implementation of emotion regulation strategies across the life span. To clarify the discrepancies in the literature, we examined the modulating influence of contextual factors in understanding emotion regulation strategy use in older and…

The present study examined consistency and inconsistency in adolescents' ethnic identification (i.e., self-reported ethnicity) across the 6 middle-school semesters. The sample (N = 1,589, of whom 46% were boys and 54% were girls) included African American, Asian/Pacific Islander, Caucasian/White, Latino/Latina, Mexican/Mexican American, and…

Findings indicated that low levels of word recognition skills, which are characteristic of dyslexic children, persist into adulthood, particularly in terms of slow word recognition. Further, adults with childhood diagnoses of dyslexia do not use word-recognition processes that are appropriate for their age level or, in some cases, for their…

Examined effects of contextual and individual differences on mothers' autonomy support versus control on homework-like tasks with their third-grade children. Found that mothers in the high-pressure condition were more controlling on the poem task. For the map task, mothers with initial controlling styles in the high-pressure condition were more…

Maintains that (1) research questions must address intra- and extraorganism contextual relations and must be multidisciplinary in scope; (2) research must be sensitive to contextual variability and individual differences; and (3) scholars must develop empirically generative models linking the development of human beings with changing contexts.

Three studies explored age changes and individual differences in preschoolers' sustained attention in different contexts. Found that changes occurred earlier for play and television viewing than for reaction time tasks. Results suggest that children have stable tendencies to sustain attention but that attention varies with task demands and…

Two experiments tested a self-regulation model of risk-taking among third through eighth graders in which inappropriate risk taking is associated with overconfidence, succumbing to dysregulating influences, and insensitivity to outcomes. Found that ability beliefs, preference for thrill seeking, peer nomination, competitiveness, and interest…

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…
