Abstract:
The aim of this study is to investigate the role of online vision of a
target object and the participant's moving hand in the early phase of
reach-to-grasp movements. We designed an experiment that separately
manipulated the visibility of a moving hand and the target object by
using two liquid crystal shutter plates placed in the same horizontal
plane (25 cm above the experimental table). When the view of the target
was available immediately after movement onset, the effect of the view
of the hand in the early phase of movement was very limited. The effect
of the view of the hand emerged when the view of the target in the early
phase of movement was not available. This was even the case for the
condition where the temporal range of non-availability of the view of
the target after movement initiation was 150 ms. Therefore, online
vision (both the view of the target and of the hand) for controlling
grasping was utilized in a flexible fashion that depended on the visual e
nvironment.
