An experiment was designed to study the effects of local electrical stimulation (LES) and verbal psychological stimulation (VPS) on the output of the fatigued muscles. The task was to operate Palmer's finger ergograph with the middle finger of the preferred hand. The LES was given by passing alternate square pulses through the operating muscles of the hand. The VPS was provided by applauding the performance of the S while he was still at work. Ten Ss provided the data under 5 experimental conditions. The results suggest that: (1) Both LES and VPS tend to increase the output as measured by the ergograph. (2) LES is superior to VPS in the initial stages of the work period but the situation is reversed at a later stage. (3) Neither the LES nor the VPS delay or enhance the onset of fatigue but they tend to increase the duration of work period when applied in the after decline period. (4) Continuous application of LES leads to rapid adaptation to its effect in comparison with VPS.
