The effect of fixed duration stimulus magnitude upon reaction time to a response terminated stimulus.

Abstract

"The present experiment was designed to test the hypothesis that the facilitation of reaction time by the condition of response termination of the auditory stimulus is a function of the duration of the fixed duration stimulus paired with it." Using separate groups of subjects, fixed duration intervals of 100, 200, 400, 800 and 1400 ms. were compared with the response terminated reaction times. "A statistically significant reduction in reaction time to the response terminated stimulus condition was found for the groups which received durations of 400, 800, 1400 and 2000 ms." The size of the differences increased progressively from 100 to 1400 ms. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
