Kinematic analysis of prehension movements in children.
The kinematics of the reach-to-grasp movement were analyzed in ten healthy children (age 6-7 years) under different experimental conditions: distance and size of the target objects, and visual feedback during the reach were varied in a within-subjects design. To assess age-related differences, the same experiments were performed in ten healthy adults. The experimental set-up was scaled accordin...
متن کاملHow Vision Affects Kinematic Properties of Pantomimed Prehension Movements
When performing the reach-to-grasp movement, fingers open wider than the size of a target object and then stop opening. The recorded peak grip aperture (PGA) is significantly larger when this action is performed without vision during the movement than with vision, presumably due to an error margin that is retained in order to avoid collision with the object. People can also pretend this action ...
متن کاملKinematic Analysis of Human Goal Directed Movements
One of the major goals of robotics research is the construction of humanoid robots that enter human-centred environments. To promote man-machine interaction in daily life robots should have a roughly humanoid shape and use human-like movements. It is therefore crucial to understand how humans coordinate their upper-body movements during daily motor tasks. One of the key assumptions in motor con...
متن کاملPostural control of three-dimensional prehension movements.
This experiment was carried out to test the hypothesis that three-dimensional upper limb movements could be initiated and controlled in the joint space via a mechanism comparing an estimate of the current postural state of the upper arm with a target value determined by one specific inverse static transform converting the coordinates of the object into a set of arm, forearm, and wrist angles. T...
متن کاملAttentional Selection during Preparation of Prehension Movements
In two experiments coupling between dorsal attentional selection for action and ventral attentional selection for perception during preparation of prehension movements was examined. In a dual-task paradigm subjects had to grasp an X-shaped object with either the left or the right hand's thumb and index finger. Simultaneously a discrimination task was used to measure visual attention prior to th...
