Effects Of Foreperiod Regularity And Muscle Size On Fractionated Reaction Time, Ronald Joseph Benedict Ii

Wayne State University Dissertations

Fractionating reaction time (FRT) chronometrically separates central (PMT) from peripheral (MT) processing, allowing for analysis of the variables that may have a timing effect on either. The purpose of this study was to determine the effect of foreperiod regularity and muscle size on the components of FRT. Forty-four male (n = 21) and female (n = 23) healthy Wayne State University students responded to a visual stimulus in a simple reaction time task, either by alternating foreperiod by block (Exp1) or by alternating muscle size by block (Exp2). All participants completed six blocks of eight trials using their right-side, with …
