Within 5 minutes after initial contact rats show excessive consumption of a mixture of saccharin and glucose solutions. With a glucose solution in one bottle and the saccharin solution in another, a combination of which matches the above mixture, the rats also show large intakes. The pattern of drinking from the glucose and the saccharin bottles indicates that the rat mixes the solutions in rapid order, producing the preferred concentration of saccharin and glucose.
在初次接触后的5分钟内，大鼠会过度饮用糖精和葡萄糖溶液的混合物。若一瓶装有葡萄糖溶液，另一瓶装糖精溶液，二者混合后与上述混合物匹配，大鼠同样会大量饮用。从装有葡萄糖和糖精的瓶子饮水的模式表明，大鼠会迅速将两种溶液混合，调配出其偏爱的糖精和葡萄糖浓度。
