Accuracy of perception of 4 numbers tactilely presented to fingers of both hands by 56 right-handed adult males who were hospitalized but showed no positive neurological signs was greater for the left hand. Middle fingers were superior; number 4 was most easily identified. Findings suggest superior capacity of the right hemisphere for this task.
