Eye preference patterns among left-handed adults.
The sidedness congruency of limb (hand and foot) and eye preference was studied in a sample of 387 adults, ranging in age from 18-94 years. The sample contained approximately equal numbers of right- and left-handers. Results revealed that both right- and left-handers displayed a percentage incidence of congruency with eye preference that was greater than chance. In addition, the incidence of hand-eye congruency was higher among older adults. The odds of the occurrence of left eye preference were increased in the presence of either left hand or left foot preference in all of the age groups studied. The present findings are consistent with the results of a recent meta-analysis on the relationship between hand and eye preference conducted by Bourassa, McManus, and Bryden (1996); these results are also consistent with the idea of a common mechanism underlying limb and eye lateral preferences.
