我养了两只小鸡,由于它经常吃到我拍落的苍蝇,逐渐建立起来一定的条件反射:起初每当听到嘭、嘭的拍蝇子的声音时,它们就赶快跑来就食。每当听到“嘭”的蝇拍子响了一声,它们一定赶快跑到响声的附近聚精会神的寻找拍落的苍蝇。后来棍子敲打声建立超使它表示“无关”的反射。最后它每当看到我拿起镶着红边的蝇拍时就唧唧的表示即将就食的“兴奋”状态。而且当我拿起一塊红布时它就不再“兴奋”了。 I raised two chickens, and as I often eat the flies that I shoot, I gradually build up some conditioned reflexes: at first, whenever I hear the sounds of mythos and mythos, they come and eat . Whenever they hear the bream fly, they must hurry up to the furious sounding flies looking for flies. Later the stick beat sound builds super-so that it means “unrelated” reflections. Eventually it shudders every time I see the swathes of red-edged fly swathes showing the “excited” state about to eat. And it’s no longer “excited” when I pick up a red cloth.
