Response times were obtained from 9 Ss responding to DC electrocutaneous signals. Each S received a series of 160 signals varying randomly in inter-signal interval (response to onset of next signal) and location. The results indicated that of the 5 inter-signal intervals employed, those being 7, 10, and 12 sec. in duration produced faster mean response times than those of 2 and 4 sec. Response times to the locations, the left hand, left foot, right hand, and right foot, did not differ significantly from one another but significantly interacted with Ss.
