Substitution of regular partial reinforcement for random one (in both cases the reinforcement frequency was 50%) acted in some dogs as a neurotizing factor: they showed unrest, stable defensive reflexes disappeared, corresponding changes were observed in vegetative reactions. At the same time activation of the sympatho-adrenal system was recorded along with a drop in concentration of acetylcholine in peripheric blood. It is noted that the development of neurotic disturbances in dogs in these conditions were to a certain degree dependent of the dominating motivation.
用固定部分强化替代随机强化（两种情况下强化频率均为50%），在一些狗身上起到了神经化因素的作用：它们表现出不安，稳定的防御反射消失，在植物性反应中观察到相应变化。与此同时，记录到交感 - 肾上腺系统激活，外周血中乙酰胆碱浓度下降。值得注意的是，在这些条件下狗的神经紊乱发展在一定程度上取决于主导动机。
