Biological and Social Correlates of Mental Development in Young Children.
Hartlage, Lawrence; And Others
A longitudinal study of mental development during the first 6 years of life was conducted to determine whether different social and biological variables were related to mental development at different ages. A total of 218 children having complete neonatal records of 12 biological variables were studied at 6-month intervals until the children were 2 years of age and at annual intervals until the children were 6 years of age. Biological variables included gestational age, birth weight, and Apgar ratings at 1 and 5 minutes. Social variables such as maternal age and education, paternal age and education, number of siblings, and family position were also recorded. Testing at 6, 12, 18, and 24 months was done on the Cattell Infant Scale of Development, with later testing being performed on the Stanford Binet, Wechsler Preschool and Primary Scale of Intelligence, and Wechsler Children's Scales. Mean developmental quotient (DQ) and intelligence quotient (IQ) scores were correlated over time; tests for significance of differences in mean DQ and IQ over time were also computed. Correlations of each biological and social variable with DQ or IQ were computed at each age level. Also computed at each age level were multiple stepwise regressions, with DQ or IQ as the criterion variable. Results indicated that biological variables were related to mental development in children up to 2 years of age, with social variables becoming more important after the second year. (RH)
