前面我们特别强调了动物行为先天成分和自发成分,同时也指出了反射和复杂行为之间的差异,但是,各种先天行为型也以多种不同的方式受外界刺激的影响。同反射行为相比,先天行为型被外界刺激激活的方式是很不相同的。外界刺激不仅可以影响动物的运动方向,而且也可以影响动物的动机。一、刺激过滤(Stimulus filtering) In the foregoing, we have particularly emphasized the congenital and spontaneous components of animal behavior. We have also pointed out the differences between reflection and complex behavior. However, various innate patterns are also affected by external stimuli in many different ways. Compared to reflexive behavior, the behavior of innate behavioral activation by external stimuli is quite different. External stimuli can not only affect the animal’s direction of movement, but can also affect the animal’s motivation. First, Stimulus filtering
