The Isochronic Component of Pointing Movements in children aged from 26 to 40 months

Résumé

This study looks at the isochronic component of pointing movements. Eleven children between the ages of 26 and 36 months at the beginning of the study performed a pointing task twice, at a 4-month interval. The location of the target was defined by its distance from the child (13 or 20 cm) and its direction with respect to the child's mid-body line (5 positions, ranging from 90° to the right and 90° to the left). A kinetic analysis of movement time and mean speed showed that isochrony can account for the organization of movement during the third year: mean speed was increased when the distance to cover was longer, in such a way that movement time remained constant. This compensation mechanism was found already at 26 months, regardless of where the target was located.
