摘要: Abstract One hundred and fifty-five preschool children between 2 case;1 5 yr of age were administered two dichotic tests (digit nonverbal sound) three Wecheler Intelligence subtests (vocabulary, geometric design block design). The familial dextral (FD) around 4 older demonstrated a greater degree absolute ear laterally than the FD under age. There also age-related changes in relationship children's ability scores their laterality scores. For right-ear advantage for verbal stimuli left-ear was associated with higher vocabulary Under age, however, strong relatively spatial ability. these younger children, less marked predicted It is hypothesized that cortical organizational transition occuring this involves shift from reliance on subcortical to mediation, accompanied by increasing callosally mediated inhibition integration hemispheric function. Furthermore, there sex differences observed lateral specialisation As young as boy's positively having sound stimuli. girl's not significantly related sounds but In addition, difference which found suggested maturation right mediation may be delayed or inhibited girls.
