Maturation rate and spatial, verbal, and musical abilities: a seven-year-longitudinal study

Journal/Book: Int J Neurosci. 1991; 58: 183-98.

Abstract: We traced spatial, verbal and musical abilities through a seven-year period of adolescence. When we started our study, 60 boys had reached a mean age of 11.72, 60 girls were 11.52 on average. Menarche and mutation served as markers for maturation. We found that early, mid, and late maturers differed on spatial orientation and on tactile- visual discrimination as measured with the Witelson task. No differences between the maturational groups emerged on verbal fluency and on Wing's Standardized Tests of Musical Intelligence. At some stages, sex differences on spatial, verbal, and musical tests emerged, and disappeared at others. The sex differences in performance levels were not associated with a sex-specific relationship between maturation rate and performance levels. We found indications of the usefulness of sex hormone measurement in relation to cognitive and musical development in adolescence.
