The experiments were designed to examine the effect of task constraints on the influence of kinematic information feedback to facilitate the acquisition of discrete arm movements. The findings of Experiments 1 and 3 revealed that when the criterion kinematic trajectory was an increasing acceleration

## Abstract This study examined the role of sensorimotor system noise in the organization of the force output of the thumb and index finger and the coordination between the two digits in an isometric pinch grip force task as a function of age (6, 8, 10, 18–22 years), feedback condition (with and wi

This study examined the influence of body scale on the grip configurations used by young children (6-12 years old) to displace cubes that varied systematically in size (L) and mass (M). It was determined if the scaling relation we had developed for adults K = log Lc + ((log Mc)/(a + bLh + cMh)) wher

## Abstract Neural activity in the motor cortex and its descending projections is modulated in a task‐related manner. Several TMS studies have shown that when normal human subjects execute different manual tasks requiring similar contraction levels in first dorsal interroseous (FDI) there is a task
