Problems in the assessment of hand preference.
Hand preference for the original items proposed by Oldfield (1971) and information concerning age, sex, familial sinistrality were obtained from a population of 1694 subjects. An item analysis was performed which resulted in the elimination of some of the items. Handedness distribution derived on the basis of the selected items was compared with the distribution obtained on the basis of the Oldfield's selection. Results show that handedness distributions depend on item selection, familial sinistrality and age, while no effect of sex is found.
