RELATIONSHIPS AMONG HANDEDNESS, FAMILIAL HANDEDNESS, SEX AND OCULAR SIGHTING-DOMINANCE

Fifty-four males and 71 females were tested on a measure of handedness and a measure of ocular sighting-dominance. Familial handedness was also ascertained via the handedness questionnaire. There were no sex or handedness differences in the incidence of familial sinistrality. Handedness, sex and familial handedness affected sighting-dominance in complex and unexpected ways. It is suggested that these variables, as well as others not tested here, will need to be considered in future studies of ocular laterality and its relationship to functional cerebral asymmetries. © 1979.
