摘要:Summary: From the view-point of developmental stages the timing-error in striking a movrng mark was observed among ten boys and girls eack from the second-grade to fifth-grrde as the subjects of this study. 1) No grade wise dfferonces both in C.E. (Const ant Error) and V.E. (Variable Error) were found when the response-records were not reported to the subgeicts. 2) The difference was found among boys in the first and secoud ten trials, when the response-recoards were reported to the subgects. 3) It was found that the timing error dependeuds on the starting-time when the timing-action was divided into starting-time and working-time. 4) The starting-time and working time among lower-grades boys and all girls of each grades were more variable when the response-records were reported the vbgects. From the above results, the development of timing ability seems to lie in the adjustment-process by means of knowledge.
