At five stages of an ongoing longitudinal study with adolescents, we compared three groups of male and female adolescents having different levels of musical abilities. Once a year, participants were tested for musical talent, dichaptic and dichotic performance, and spatial and verbal ability. Of 60 boys, 12 were left-handed; of 60 girls, 7 were left-handed. Left-handedness was related to musical talent and to the ability to compose/improvise in boys but not in girls. No differences were found between left-handers and right-handers on dichaptic and dichotic tasks. However, musical talent influenced the outcome. Compared with right-handedness, left-handedness in both sexes was associated with a significantly higher incidence of asthma, allergies, and/or migraine.
