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 study of the stability of parent behaviors toward toddlers over a 3-week period used both aggregated and nonaggregated data. Comparison of stability correlations indicated higher stabilities for aggregated scores, with the level of stability increasing as scores from additional single sessions were aggregated. (PCB)

This critique points out weaknesses regarding the test measures used by Munsinger and Douglass and questions the validity of these measures for the ages of the children used in their study. (JMB)

This paper suggests that, at present, a science of natural developmental processes does not exist because few studies are concerned with development as it transpires in naturalistic environments and because truly developmental data are not collected or analyzed. (Author/JMB)

Paper considers some of the problems facing the researcher interested in patterns of abilities as revealed by a discussion of the Lesser studues (1971), presentation of reanalyses of their data, and a critical review of the research. (Author/CB)

Outerdirectedness has been defined by first author and his colleagues as a style of problem solving characterized by reliance on concrete situational cues rather than by active attempts to deduce abstract relationships. (Authors/MB)

Study is concerned with the commonalities between the development of skill and the development of problem solving. (Authors)

Shares three ideas concerning how to evaluate the practical importance of developmental findings to make them more useful to policymakers: (1) statistical significance tests need to be accompanied by effect size estimates; (2) meta-analyses are helping in using all existing data when examining issues involved in policy debates; and (3) researchers…

Groups trained to compare the whole and subset improved in cue identification from negative instances; performance in the stimulus exposure group declined. (Authors)

In research with children, there is a common problem which could reduce the reliability of a questionnaire for some children but not others: verbal comprehension. (Authors)
