Abstract

An attempt was made to induce polydipsia in rats whose lever pressing was reinforced with food pellets or electrical brain stimulation. Nine food-deprived, water-sated rats drank water excessively during sessions in which food pellets were delivered. When brain stimulation was substituted for food, drinking immediately ceased. Delivering brain stimulation according to a variety of schedules, pairing brain stimulation with food reinforcement, and substituting an air stream for water, each failed to produce polydipsic licking. These results show that polydipsia is not induced by all reinforcers.

摘要

研究人员试图在通过食物颗粒或脑电刺激强化杠杆按压行为的大鼠中诱导其出现烦渴症。九只处于食物剥夺状态但水分充足的大鼠在给予食物颗粒的实验过程中过度饮水。当用脑电刺激替代食物时,饮水立即停止。按照各种时间表给予脑电刺激、将脑电刺激与食物强化配对以及用气流替代水,均未能产生烦渴性舔舐行为。这些结果表明,并非所有强化物都会诱发烦渴症。
