Research Findings: In order to examine the explanatory power of behavioral self-regulation in the domain of emotion knowledge, especially in a non-U.S. culture, 365 German 4- and 5-year-olds were individually tested on these constructs. Path analyses revealed that children's behavioral self-regulation explained their emotion knowledge in the…

Aging effects on the Wisconsin Card Sorting Test (WCST) are fairly well established but the mechanisms of the decline are not clearly understood. In this study, we examined the cognitive and neural mechanisms mediating age-related increases in perseveration on the WCST. MRI-based volumetry and measures of selected executive functions in…

Used path analysis in two experiments to examine possibility that age difference in infants' long-term retention were artifacts of correlated differences in learning rates or learning opportunities. Found that developmental declines in forgetting rates between 12 and 18 months were independent of developmental differences in learning. Age…

Two experiments involving students from grades 1-2 and 5-6 found strong connections between development and forgetting rates when the influences of learning ability were eliminated. Findings eliminated a hypothesis based on age variability in overlearning. (RH)

Examined knowledge about medicines and perceived benefit among 101 children, ages 7 and 10. Found that medicine knowledge was explained using age, educational environment, and degree of internal locus of control as significant predictors. The negative effect of internal locus of control predicted perceived benefit. Retention of drug advertising…
