对不同海拔地区小学生的选择反应时进行了测定与比较。结果表明：海拔与小学生的选择反应时有高度的相关，从平原升至海拔2261米时小学生的选择反应0时间无显著性变化，从海拔2261米升至海拔4273米时小学生的选择反应时间明显延长；随年龄升高，小学生的选择反应时间缩短；随测试难度的增加，小学生的选择反应时间延长。 The responses of primary school students at different altitudes were measured and compared. The results showed that Altitude was highly correlated with the choice reaction time of pupils. There was no significant change in response time of primary school students when the altitude was 2261 meters above sea level. From 2261 meters above sea level to 4273 meters above sea level, the response time of pupils was obviously With the increase of age, the choice reaction time of primary school students is shortened. With the increase of test difficulty, the choice reaction time of primary school students is prolonged.
