Effects of Preparatory Period on a Reaction-Time Followed by a Pointing Movement Either Guided or Not
Yves Guiard, Jean Requin · Perceptual and Motor Skills · 1973
In a pointing task, the movement-time (MT), as opposed to reaction-time (RT), does not depend upon duration of preparatory period (PP). On the other hand, the mean MT, but not the mean RT, is shortened by guidance of the movement. The timing of preparatory processes in such task is discussed.
