Muscle Action Potential and Hand Switch Disjunctive Reaction Times to Visual, Auditory, and Combined Visual-Auditory Displays

Muscle action potential and hand switch disjunctive reaction times of three male subjects to visual, auditory, and combined visual-auditory display were observed. Muscle action potential responses were found to be considerably faster than hand switch responses. Within each response mode, reaction times with the combined display were faster than visual display reaction times.
