Approaches to Understanding Hand Skill Acquisition

The proficiency levels of using chopsticks and/or writing characters with a pencil etc. are improved by the practices continuously repeated. By the way, the mechanisms of improving the proficiency level of human skill have never been clarified. This study focused on the mechanism of our skill acquirement and investigates the change in muscular activity in the process of skill acquirement. This paper describes the experimental device we have developed, where a skilled instructor and a beginner operate the experimental device linked to a simple paddle application. We will investigate the process of human skill acquirement by focusing on the changes in the activities of brachial muscles while training. Especially, the effects of physical instruction of an instructor on the skill acquirement of a beginner will be discussed in this paper.
