In order to compare and contrast hedonic properties of 0.75 M NaCl and 0.5 M sucrose used in behavioral electrophysiology of taste, tests were carried out of evoked patterns of orolingual response and operant licking on a FR-32 schedule to discrete intraoral injections of these stimuli and other basic types of tastants. In tests of taste reactivity, NaCl and sucrose evoked quantitatively similar numbers of orolingual response in excess of those evoked by water. NaCl was also similar to sucrose in amount of operant licking generated at the outset of the test session. Both of these stimuli were more effective than either 0.02 M HCl, 0.01 M QHCl, or water. The NaCl also did not have the suppressant effect of HCl when alternated with sucrose as the reinforcement for licking. NaCl differed from sucrose in sustaining operant licking. While NaCl would appear to share the same basic hedonic value of sucrose, long-term associative processes pertaining to postingestional consequences of fluid input and short-term sensory processes may act to limit behavioral responsivity for concentrated NaCl. Additional information was obtained on operant licking for sodium saccharin.
为了比较和对比味觉行为电生理学中使用的0.75M氯化钠和0.5M蔗糖的享乐属性，针对这些刺激物和其他基本类型的味觉剂进行了离散口腔内注射，按照FR - 32程序对口腔 - 舌部反应的诱发模式和操作性舔舐进行了测试。在味觉反应性测试中，氯化钠和蔗糖诱发的口腔 - 舌部反应数量在数量上与水诱发的反应数量相似。在测试开始时，氯化钠产生的操作性舔舐量也与蔗糖相似。这两种刺激物都比0.02M盐酸、0.01M QHCl或水更有效。当与蔗糖交替作为舔舐的强化物时，氯化钠也没有盐酸的抑制作用。氯化钠在维持操作性舔舐方面与蔗糖不同。虽然氯化钠似乎与蔗糖具有相同的基本享乐价值，但与液体摄入的摄食后后果相关的长期联想过程和短期感觉过程可能会限制对浓缩氯化钠的行为反应性。还获得了关于糖精钠操作性舔舐的更多信息。
