Spaced feeding of individual food pellets to food-deprived rats induced excessive drinking after pellet delivery if water was continuously available. When access to water was restricted to a portion of the inter-pellet interval, and competition from food-reinforced bar pressing was removed, excessive drinking occurred whenever drinking was possible. This finding extends the generality of accounts of excessive behavior that implicate induction by apparently unrelated scheduling characteristics of the environment.
给食物匮乏的大鼠逐粒间隔投喂食物，如果水一直供应，在投喂食物颗粒后会引发过度饮水。当水的供应被限制在颗粒投喂间隔的一部分时间内，并且消除了来自食物强化压杆行为的竞争时，只要有可能饮水就会出现过度饮水现象。这一发现扩展了关于过度行为的解释的普遍性，这些解释涉及由环境中明显不相关的时间安排特征所引发的现象。
