Reaction Time to Onset and Termination of Lights and Sounds

Abstract

An experiment was conducted which measured the RT of 40 adult Ss to the onset and termination of rapid rise and decay lights and sounds which had been equated for subjective intensity. Onset RT was faster than termination for both sense modes, and auditory RT was faster than visual for both onset and termination. The results are compared with previous intersensory and onset-termination RT research and with another auditory-visual difference in the judgment of duration.
