Physiological Maturation and the Development of Formal Thought at Adolescence. Final Report.
Kohen-Raz, Reuven
The mental and physical development of 994 elementary school children, recruited from populations of High, Medium and Low socio-economic and educational level in Israel was followed up for two (and in part for three) years. The pupils were given mental tests to measure the ability to understand the structure and direction of second order relationships and to reason a priori, even if the correct logical deduction is dissonant with experience. Physical growth was also assessed. Elaboration of parametric correlations indicated that substantial relations between physical and mental growth show up when season of birth is controlled by dichotomizing the sample into Winter and Summer born subjects. Applying a nonparametric data analysis, based on pairs matched closely for chronological age and parental education, and using longitudinally assessed criteria of physiological maturation as independent variables, significant relationship between physiological maturation and mental growth were detected at all three socio-economic and educational levels. The findings indicate that pre-adolescence and early puberty are critical periods of maturationally determined acceleration in mental development, during which conspicuous progress is made in the ability of formal reasoning.
