Meta-analysis of the A-not-B error was conducted, using logistic regression, on studies conducted before September 1997. Results replicated earlier findings, with exception that the number of trials at the A location was a significant predictor, and the number of locations was a significant predictor of the proportion of infants who searched…

Conducted meta-analysis of preschool and early elementary school self-esteem instruments, using reliability as criterion variable and different aspects of methodology used in testing an instrument as predictor variables. Found that reliability could be predicted by study setting, number of items in the scale, age of children being studied, method…

Three sets of meta-analyses examined gender effects on children's language use. Each set of analyses considered an aspect of speech that is considered to be gender typed: talkativeness, affiliative speech, and assertive speech.

Over the past decade activists, academics, and policymakers have devoted a great deal of attention to "environmental equity," or the notion that sources of potential environmental risk may be concentrated among racial and ethnic minorities and the poor. Despite these efforts, the existence and extent of environmental inequities is still…

Research on the effect of suicide stories in the media on suicide in the real world has been marked by much debate and inconsistent findings. Recent narrative reviews have suggested that research based on nonfictional models is more apt to uncover imitative effects than research based on fictional models. There is, however, substantial variation…

Using data from 8 random assignment studies and employing meta-analytic techniques, this article provides systematic evidence that welfare and work policies targeted at low-income parents have small adverse effects on some school outcomes among adolescents ages 12 to 18 years at follow-up. These adverse effects were observed mostly for school…

Findings from research indicate that teachers participating in online professional development (OPD) activities and programmes have gained, in some way or another, a great deal of teacher competency.
