“摘苹果” 摘苹果实验是这样的:心理学家将一群学生随机分成两个小组,让他们一起摘悬于半空中的苹果。两个小组摘苹果的方法各不相同,对第一小组的学生,让他们一开始就去摘悬挂高度超过自己跳跃能力的苹果,对第二小组的学生,则将苹果悬挂在他们通过努力跳跃就能达到的高度,然后再逐步提高高度。 An apple picking experiment is like this: A psychologist randomly divides a group of students into two groups, picking them up in the air with apples. The way the two groups pick their apples varies from one group of students, so that they first pick the apples whose height exceeds their ability to jump from the start, and the apprentice to the second group hangs apples when they jump through their efforts You can reach the height, and then gradually increase the height.
