ABSTRACT

The present study deals with the influence of specific motor experiences on efficient grasp planning. Forty 5- to 6-year-old children learned to use an unfamiliar tool with either a thumb-up or a thumb-down grip to accomplish a task. Before and after training, the extent to which children would rotate the tool using an awkward initial grip (thumb-down) to ensure a comfortable end-grip (end-state comfort), a pattern that has been interpreted as representing efficient grasping, was measured. The number of thumb-down grips increased only in the group that had trained to use the tool with this specific grip, but did not change after a training with an incongruent thumb-up grip. This demonstrates how the experience with specific tool-use-related grips influences efficient grasping.

工具使用体验对儿童有效抓握的影响

摘要

本研究涉及特定运动体验对有效抓握计划的影响。40 名 5 至 6 岁的儿童学会了使用不熟悉的工具以及拇指向上或拇指向下的握把来完成任务。在训练前后,儿童使用笨拙的初始抓握(拇指向下)旋转工具以确保舒适的末端抓握(最终状态舒适)的程度,这种模式被解释为代表有效抓握的模式,是测量。拇指向下握持的数量仅在接受过这种特定握法训练的组中增加,但在拇指向上握法不一致的训练后没有变化。这展示了特定工具使用相关握把的体验如何影响有效抓握。
