Abstract: Testosterone, estradiol, and ACTH were determined in blood serum of 26 healthy males aged 19.16 and of 25 healthy females aged 18.77 years on average, and results were correlated with test scores of three spatial tests, a verbal fluency measure, and a test measuring general musical ability. In addition, hemispheric lateralization for verbal material and handedness was assessed. While testosterone and estradiol alone were not significantly related to any of the cognitive or musical tests, testosterone/estradiol ratio was significantly negatively correlated with spatial tests, and ACTH was significantly positively correlated with spatial and musical tests. Correlations were stronger in females than in males. The laterality index was significantly negatively correlated with testosterone in males indicating that right hemisphere involvement in verbal processing was associated with high testosterone levels.
