Foreperiod effects on human single motor unit reaction times.

Abstract This study analyzed the effect of foreperiod factors on key release reaction times and single motor unit reaction times. Changes in foreperiod parameters influencing overt reaction times had a similar effect on single motor unit reaction times. Both types of responding decreased in median latency values and increased in variability with the appropriate selection of foreperiod parameters. It is suggested that RT design must be carefully considered in RT studies using single motor unit techniques.
