Developmental effects and gender differences were also examined. Participants were a normal population sample of 424 (216 boys) children aged 6 to 13 years.…

Reports results of analyses of key tables in the Myers-Briggs Type Indicator Atlas of Type Tables. Significant age group effects on every dimension indicates the need to reestimate population norms for each continuum on the MBTI for interpreting scores of people of various ages. (LKS)

A test battery that corresponded to the Gesell Developmental Assessment (GDA) was given to 400 4-6 year olds. A truncated version of the GDA had moderate reliability and predictive power. Experienced judges sometimes differed in their assessments of a child's developmental level and recommendations for grade placement. (GLR)
