Effects of foreperiod, induced muscular tension, and stimulus regularity on simple reaction time.

Abstract

Found that foreperiod length and muscular tension are independent in their effects on reaction time (RT). In general, RT varies inversely with magnitude of muscular tension. There appears to be an optimum foreperiod of reaction which, in the present massed practice task, was 5-6 sec. No practice effects due to the repeated elicitation of the reaction were found.
