This paper reports findings of a study examining the degree to which intelligence, levels of sex-steroids and gonadotropins, quality of parenting and laboratory-based measures of left and right hemispheric specialization are associated with individual differences in psychosocial functioning in pre-pubertal 47,XXY males. The results indicate that activity level and freedom from tendencies towards withdrawal in these subjects are best predicted by the normality of their left hemispheric functioning.
