This investigation was designed to determine the relationship between the tactual two-point threshold and the two-point supraliminal difference limen. The yes/no method was employed and three localities were tested. The results confirmed the hypothesis that as the initial two-point threshold increases, the two-point supraliminal difference limen also increases. No significant differences were obtained between the right and the left sides of each body area tested and only on the hand was a reliable difference obtained between the first 9 and second 9 sessions. This difference was interpreted in terms of a peripheral fatigue phenomenon.
