Many difficulties are encountered in studing the cutaneous sensations. The purpose of this paper is to clarify the psychological factors in the cutaneous sensations. For this purpose the simultaneous two points discrimination was studied on the forearms of 238 patients who showed psychogenic disturbance without any sensory disturbances of the skin and the ones of 122 healthy men and women.The results were as following as : 1. Patients showed always the tendency to inaccuracy and unsteadiness in this discrimination, but the tendency was hardly showed in patients who were improved in their conditions.2. The thresholds of the discrimination obtained by the variability and variance of errors were of no differences between patients and control subjects.3.There was the close relation between the sensory pattern and the YATABE-GUILFORD personality test.Therefore it is certain that the simultaneous two points discrimination of the skin is always in the physiological limit and influenced by the psychological factors. Otherwise the simultaneous two points discrimination seems to be useful in finding the abnormal personality.
