インターパーソナルな書字訓練におけるBody Imageの拡張プロセスの解析

抄録

In this paper, focusing on the handwriting with pen or pencil which is applied at not only daily but also clinical scene, we analyzed the improvement mechanism of accuracy of the handwriting by the inter-personal handwrite-training with embodied interaction between trainer and trainee. As the results, we found the improvement of not only the accuracy but also the synchronization of handwriting between trainer and　trainee by less than the ten-times training. Also we found the characteristic phenomenon of the remarkable decline of the synchronization with the time lag of handwritings at training just before the most accurate handwriting realized. Accordingly we may say　that the accurate handwriting was realized with extension of both trainer and trainee's　own Body Images containing mutually, by visual feedback from the other's handwriting.　Therefore we suggest that the inter-personal handwrite training may urge the reconstruction mechanism of Body Images, trainer and trainee containing the other's Body Image mutually.
