Studied the relation between tactual space perception on the palm of the hand on the tongue, when estimated in terms of visual areas. 20 Ss were made to extend their palms, on which 12 stimulus rings were placed. Ss were also shown a visual chart on which 27 circles were drawn, including the 12 stimulus rings. The Ss had to identify the ring with the corresponding circle on the chart. The presentation, judgments, and records were made in the same manner for the tongue. Results reveal that: (1) perception of size was more accurate with the tongue than with the hand (2) the average deviations for both hand and tongue were approximately the same; and (3) individual variations in the estimations of sizes were greater for the hand than for the tongue.
