Abstract [en]

Hand adjustments of 6- and 10-month-old infants and adults were studied as they reached to grasp a rotating rod. It was found that the subjects in all three age groups adjusted the hand prospectively to the rotating rod during the approach of it. They also adjusted the reaches to the rotating rod in such a way that almost all of the grasps were overhand ones as predicted by the endpoint comfort hypothesis. Finally, it was found that the rotation of the hand was made up of movement units as translational movements are, and that the approach units were relatively independent of the rotational ones.
