巴甫洛夫通过训练,让狗听到铃声便不由自主分泌唾液,在此基础上创立了“条件反射学说”。但少有人知道他曾在自己弟弟身上做过实验。这个实验细节刚刚披露,这给目前用动物还是用自家亲戚做实验的争论添了一把火。 Pavlov created the “conditional reflexology” based on the training that allows dogs to hear saliva and involuntarily secrete saliva. But few people know that he had experimented with his brother. The details of this experiment have just been disclosed. This has given a fire to the current debate on using animals and their relatives to do experiments.
