成年人的口味偏好会在多大程度上受到早期味觉暴露的影响，这是一个有争议的问题。本研究描述了成年大鼠生理盐水偏好的发育过程，并研究了成年大鼠的生理盐水偏好是否受断奶后暴露于生理盐水溶液的影响。在Wistar大鼠中检测了从断奶到成年期的生理盐水摄入量，这些大鼠允许连续获得脱矿化水和0.0%、0.9%、1.8%或2.7%氯化钠(NaClw/v)溶液。当老鼠还未成熟时，它们比成年时表现出更多的盐溶液偏好。据推测，幼年动物对盐水的过量摄入与断奶早期味觉系统对氯化钠的敏感性较低有关。将断奶后不断获得盐分的动物与那些在生命早期没有接受盐分暴露的动物进行比较，以确定广泛的盐溶液经验是否会导致成人盐分偏好的改变。这些研究未能揭示任何证据表明饲养条件会影响成体的食盐偏好；因此，成体的食盐偏好可能是成熟的决定的，并且相对独立于断奶后的环境影响。
The degree to which adult taste preferences can be influenced by early taste exposure is a matter of some debate. The present studies characterize the developmental course of saline preference during maturation in the rat and examine whether adult saline preference is influenced by postweaning exposure to saline solutions. Saline intake from weaning to adulthood was examined in Wistar rats allowed continuous access to demineralized water and either .0, .9, 1.8, or 2.7% sodium chloride (NaCl) w/v solutions. When rats were immature they expressed greater preference for saline solutions than they did as adults. It is hypothesized that the overconsumption of saline by young animals is related to lower sensitivity of the taste system to NaCl in the early postweaning period. Animals that had had continuous access to saline from weaning were compared to those that had not received saline exposure early in life, in order to determine whether extensive experience with salt solutions leads to alterations in adult salt preference. These studies failed to reveal any evidence that rearing condition affects adult salt preference; thus adult salt preference may be maturationally determined and relatively independent of postweaning environmental influences.
