Increased negative discordance of the dominating mode of the pressing duration histogram (PDH), which correlates with the growth of fixed bursts of stimulation is accompanied by a progressive decrease in the reinforcing properties of self-stimulation (SS), avoidance of the pedal and at the same time by a change of behavioral grooming reactions in the intervals between SS for search and consummatory reactions. Hunger considerably shortens the preferable duration of pressing or leads to the appearance of an additional mode on the PDH. With the change of the dominating PDH mode from positive discordance to a negative one, brain stimulation acquires aversive properties which are apparently due to the activation of the mechanisms of specific motivations.
按压持续时间直方图（PDH）主导模式的负向不一致性增加，这与固定刺激爆发的增长相关，同时伴随着自我刺激（SS）强化特性的逐渐降低、对踏板的回避，并且在SS之间的间隔中，行为梳理反应会发生变化，以进行搜索和完成反应。饥饿会显著缩短按压的偏好持续时间，或导致PDH上出现额外的模式。随着PDH主导模式从正向不一致转变为负向不一致，脑刺激获得了厌恶特性，这显然是由于特定动机机制的激活。
