Abstract :

Tool use is a goal-oriented manipulation of an object that demands highly cognitive efforts. Shibuya demonstrated that some children notably lacked the precision to cut figures on a paper although they appropriately held scissors. This might be caused by poor motor planning and control. This study aimed to examine children�??s knowledge of a strategy of the motor planning and control to use scissors purposefully. Study 1 investigated how children understood the knowledge of �??trade-off�?� relationship between motor speed and motor accuracy. It was hypothesized that children who understood the �??trade-off�?� relationship would be good at motor planning which would let them cut a circle accurately. As a result, predictably, the first-graders could answer more correctly and cut more accurately than the preschoolers, but the motor speed of cutting a circle was not much different. Then, the children were classified into two groups according to their response to the knowledge problems; �??well understanding�?� and �??poor understanding�?�. The �??well understanding�?� group cut more accurately than the other group in a marginal significance. However, several children in the �??poor understanding�?� group cut a circle without any error and vice versa. These results suggest that the knowledge of �??trade-off�?� relationship partly influences children�??s motor performance, but it is just one of the factors. In Study 2, based on the results of Study 1, we focused on the different aspects of children�??s knowledge related to movement, that is, the knowledge of smooth bimanual coordination strategy. Specifically, whether the children understood that bracing and rotating a paper by non-dominant hand affect motor accuracy was examined. Based on the results of Study 1 and 2, the influence of children�??s recognition related to movement on their motor performance will be discussed in the session.
