The water intake of food-deprived rats was evaluated under conditions where liquid food was presented occasionally. In the first experiment, when soybean milk alone was presented every 30 sec, little water was consumed. However, when sodium chloride was added to the soybean milk, water intake increased directly with salt concentration from 0.9 to 14.4%. At salt concentrations of 7.2 and 14.4%, the drinking induced by soybean milk resembled in several respects the adjunctive drinking educed by spaced presentations of dry food. In a second experiment, adulterating soybean milk with sugar in concentrations of 7 to 56% did not affect water intake significantly when the food was delivered every 30 seconds. These findings extend the range of conditions known to generate schedule-induced drinking, and point out a previously unknown constraint on the phenomenon.
在偶尔提供流质食物的条件下，对食物被剥夺的大鼠的水摄入量进行了评估。在第一个实验中，每30秒仅提供豆浆时，几乎没有消耗水。然而，当向豆浆中添加氯化钠时，水摄入量随盐浓度从0.9%直接增加到14.4%。在盐浓度为7.2%和14.4%时，豆浆诱导的饮水在几个方面类似于由间隔投喂干食物引发的辅助性饮水。在第二个实验中，当每30秒提供一次食物时，用浓度为7%至56%的糖掺杂豆浆对水摄入量没有显著影响。这些发现扩展了已知会产生定时诱导饮水的条件范围，并指出了该现象之前未知的限制因素。
