Bronfenbrenner's (1979) ecological model proposes that events in higher order social ecosystems should influence human development through their impact on events in lower order social ecosystems. This proposition was tested with respect to ecological violence and the development of children's aggression via analyses of 3 waves of data (1 wave…

This article presents a scheme which would allow investigators to shift back and forth among model assumptions while maintaining the integrity of separate models of development. The scheme is illustrated in a study of 16 nursery school children's personal-social behaviors within 2 contexts during 2 time periods. (Author/JMB)

Decribes age trends in television viewing time and visual attention of children and adults videotaped in their homes for 10-day periods. Shows that the increase in visual attention to television during the preschool years is consistent with the theory that television program comprehensibility is a major determinant of attention in young children.…

Examines the implications of temporal separation for children's developmental differences in inferences drawn about an individual's characteristics after observing multiple instances of that individual's behavior. Also tests two competing hypotheses about how young children process information separated in time. (HOD)
