 When reaching for an object, the proximity of the object, its orientation, and shape should all be correctly estimated well before the hand arrives in contact with it. We were interested in the effects of the object’s orientation on manual prehension. Subjects were asked to reach for an object at one of several possible orientations. We found that the trajectory of the hand and its rotation and opening were significantly affected by the object’s orientation within the first half of the… CONTINUE READING
