title: Sex differences and asymmetry of lexical processing: effects of responding hand, stimulus familiarity and intraexperimental experience.
abstract: The possibility that language processing functions are more nearly equally represented in the two hemispheres of women than of men was investigated tachistocsopically by means of a lexical decision task in which words and nonwords were controlled for familiarity, and exposed vertically in the left and right visual half-fields. Analysis of both unimanual reaction times and response accuracy revealed differences in asymmetry as well as differences between male and female subjects which tended to decrease as a function of intraexperimental experience. Theoretical and methodological problems associated with reaction time and response accuracy as measures of language lateralization are discussed.
