To study the possibility that the level of skilled visual-tracking performance by primates would deteriorate under the influence of radiofrequencyirradiation. The monkeys were motivated by mild electricalstimulation to maintain a circular cursor within the center 15% of an oscilloscopic display. The cursor was driven off this safe on-target area by a complex sinusoidal track that covered 40% of the display. For each one second accumulated outside this area, the animal received a 0.1 s low-intensity electrical shock (1.0 mA).
The data from exposuresessions showed no decrement relative to control data. It is concluded that the exposures at 10 and 20 mW/cm² did not have deleterious effects upon the skilled performance of a moderately large monkey.
