The current paper investigates the structural validity of the Children's Concentration and Empathy Scale (CCES), which was designed based on Montessori's developmental theory to assess, using teacher ratings, the coherence of attention-related characteristics (concentration, empathy, and normalization) in children from 1.5 to 12 years old. The…

Investigated the criterion-related validity of the Minnesota Child Development Inventory (MCDI) for 30-month-old children (N=122). Results showed that MCDI scales correlated with cognitive but not motor development as measured by the McCarthy scales. The MCDI accurately identified children performing below normal in general cognitive development.…

An experiment was conducted to confirm that egocentrism demonstrated in Piaget's 'three mountain' experiment was more a function of experimental design than of children's thought. (Author)

When administered to 34 infants with handicaps, Bayley Scale mental age scores were an average of 2.1 months higher than Estimated Developmental Ages (EDA's) calculated from the Uzgiris and Hunt Scales. The EDA's were significantly and positively related to Bayley mental age, and sensorimotor play emerged as the best single correlate. (Author/JDD)

The authors examined aspects of reliability and validity of the Goode-nough-Harris Draw-A-Person Test (DAP; D. B. Harris, 1963). The participants were 115 seven- to nine-year-old students attending regular or special education schools. Three judges, with a modest degree of training similar to that found among practicing clinicians, rated the…
