奥地利生物学家康拉德·劳伦兹曾对动物做过一组有趣的训练实验。他把家养的一种灰腿鹅的蛋分作两组孵化。一组由母鹅孵,孵出的雏鹅最先看到的是它母亲的活动,于是母鹅走到哪里,雏鹅就摇摇摆摆,亦步亦趋地跟到哪里。第二组是放在人工孵化器里进 The Austrian biologist Conrad Lorenz had done an interesting set of training experiments on animals. He hatched the eggs of a domesticated gray-legged goose into two groups. One group was hatched by mother goose. The hatchling gosling first saw its mother’s activities. So where the mother goose went, the gosling swayed and followed. The second group is placed in the artificial incubator.
