Context In a more recent experiment Georgopoulos and Massey (1987) requested subjects to perform reaching movements at various angles from a stimulus direction and found that duration of reaction times of these movements was proportional to the size of the angle. They proposed that the increase in reaction time was related to rotating mentally the movement vector until the angle of rotation corresponded to the size required. This relationship, which is reminiscent of the classical relation between movement time and task difficulty observed during execution of real movements (Fitts, 1954), suggested to Georgopoulos and Massey that both real and imagined motions might be governed by the same principles.
