The speed of visually triggered movements depends, among other things, on the time needed for visuomotor transformations. We show that it takes on average 20–40 msec less time to respond to visual stimuli when they are projected on the reacting fingers than a few centimeters away from them. The result implies significant preference of the personal space to the extrapersonal space for stimuli used in the initiation of visually triggered movements.
