The unilateral forms of finger 'agnosia' (UFA) were studied in 60 control and in 176 brain damaged patients by means of a nonverbal test of finger localization. Both right and left brain damaged patients showed a prevalence of finger agnosia on the hand contralateral to the damaged hemisphere, but this prevalence was significantly more important in the right hemispheric group. When the task performed was under visual control, the prevalence of UFA among the right brain damaged patients seemed due mostly to unilateral spatial neglect, but this interpretation could not account for the results obtained with the hands hidden from view. Some implications of these findings are discussed.
