Handedness and Career Choice: Another Look at Supposed Left/Right Differences
Numerous studies have considered the possibility of consistent differences in the percentages of left- and right-handers in verbal and visuospatial career fields and academic disciplines. Conflicting results have supported hypotheses suggesting more left-handers in visuospatial fields, fewer left-handers in visuospatial fields, and no differences between the percentages of left- and right-handers in visuospatial and verbal fields. The present study sought to examine further the possibility of differential distributions of left-and right-handers in verbal and visuospatial fields by considering hand preferences of 109 faculty members in the architecture college, art department, law college, and psychology department at The University of Arizona, Tucson, Arizona. No significant differences were found in reported handedness, hand position in writing, or familial handedness for the verbal and visuospatial groups. Results were discussed in relationship to methodological difficulties of previous studies and the overemphasis of the impact of cerebral dominance on functioning in normal individuals.
