The difference was studied between use of the dominant hand and non-dominant hand in the transfer time of a cotton sample by using chopsticks and a spoon. The effect of training on the transfer time of the cotton sample by chopsticks in the dominant hand and non-dominant hand was also examined. The transfer times of a sample by chopsticks and spoon were significantly shorter when held in the dominant hand than in the non-dominant hand. The transfer time of a sample in the dominant hand was significantly longer by spoon than by chopsticks. However, no significant difference was apparent in the transfer time of the sample between the chopsticks and spoon in the non-dominant hand. Training in manipulating the chopsticks significantly reduced the transfer time of a sample in the period from 6 to 10 days after starting the training, and this reduced transfer time was maintained 45 days after the cessation of training. These results suggest that the hand dominance for using chopsticks was more prominent than that for spoon use and that training for chopstick use was more effective for the non-dominant hand, with the effect being maintained for a long period of time.
