Reactions achieved by the mechanism of backward connection were studied in unrestrained dogs with acoustic stimuli preceded by an alimentary unconditioned reflex: a 300 c/s acoustic stimulus was paired with feeding from the left feeding trough and 1000 c/s stimulus--with the right feeding trough. A certain dynamics was observed in the manifestation of these reactions. As the number of tests increased, the number of specific reactions diminished, while non-specific reactions and reactions of running to the door appeared. Acute extinction of the running reflex to the sound of the feeding trough has been shown that the dynamics of reactions to the later is the same as in tests to the tone. Proceeding from this, it may be assumed that the evolution of backward connections manifestation is based on extinctive inhibition which develops in consequence of non-reinforcement of conditioned stimuli in the tests on backward connection formation.
在无拘束的狗身上研究了通过反向联系机制实现的反应，这些狗在进食性非条件反射之前接受听觉刺激：300赫兹的听觉刺激与从左侧喂食槽喂食配对，1000赫兹的刺激与右侧喂食槽配对。观察到这些反应表现出一定的动态变化。随着测试次数的增加，特异性反应的数量减少，而非特异性反应和跑到门口的反应出现了。已经表明，对喂食槽声音的奔跑反射的急性消退，对其的反应动态与对音调的测试相同。据此可以假设，反向联系表现的演变基于消退性抑制，这种抑制是在反向联系形成测试中条件刺激未得到强化的情况下产生的。
