| 抄録: | The purpose of our experiment is to clarify how the batter perceives the speed of the second ball thrown at him after experiencing the speed of the first ball. 16 combinations of four ball speeds, 110km/h, 120km/h, 130km/h and 140km/h, were studied in 36 high school baseball players. The main results of the experiment are summarized as follows: 1. If the speed of the second ball was equal to that of the first ball, the batter perceived the former to be equal to the latter, regardless of the speed applied. 2. If the speed of the second ball was faster than that of the first ball, it was observed that the greater the difference between the speeds of the two balls, the faster the batter perceived the speed of the second ball to be. 3 If the speed of the second ball was slower than that of the first ball, it was observed that the greater the difference between the speeds of the two balls, the slower the batter perceived the speed of the second ball to be. |
