Ss controlled a rotating disc for 10 min., with instructions to keep the speed of the disc constant. Ss actually increased the physical speed of the disc as the trial continued. The logarithmic increase in speed was proportional to the square root of the inspection time and was less for high initial speeds than for low. It was proportional to the Weber ratio. Most Ss showed less neutralization on the later trials.
