Aging, expertise and fine motor movement.

摘要: Age-graded decrements in accuracies and maximum speed of fine motor movements observed numerous experimental studies have nurtured general factor explanations like the assumption age-related slowing central cognitive processes. This review focuses on two domains investigation that yielded challenges to models. First, approaches aiming at decomposition skills provide evidence for dissociability timing, sequencing, executive control components show differential rather than changes. Second, cognitive-motor expertise demonstrate changes critical skill depend individuals' time investments into specific practice activities. It is argued process dissociations behavioral level developmental (i.e. age expertise) reflect long-term adaptations internal external performance constraints. The outcomes these adaptation processes are stable interindividual differences component
