Abstract:
The paper-and-pencil spatial performance of right- and left-handed high school students was compared separately for 1236 males and 1241 females. Handedness differences in favor of right-handed subjects were found among males only. Analysis of data for a subgroup of 555 subjects indicated that handedness and sex-linked genetic effects acted independently and additively on spatial performance.
