味觉回避和味觉厌恶：两种不同过程的证据
作者：
L. Parker
条件性味觉回避和条件性味觉厌恶这两个术语在文献中经常互换使用;然而，大量证据表明它们可能代表不同的过程。条件性味觉回避是通过大鼠在消耗测试中消耗的量来测量的，该消耗测试包括食欲阶段和反应的完成阶段。然而，条件性味觉厌恶更直接的评估与味觉反应性测试，其中包括只有完善阶段的反应。大鼠在口内输注恶心配对调味溶液期间显示条件性味觉厌恶作为条件性排斥反应（张口、下巴摩擦和爪踏）。产生恶心的治疗对于建立味觉回避不是必需的，但它们对于建立味觉厌恶是必需的。此外，缓解恶心的治疗既不调节味觉回避的建立也不调节味觉回避的表达，但它们干扰味觉厌恶的建立和表达。大量证据表明，这两项措施是相互独立的。味觉回避可能是由条件性恐惧而不是条件性恶心引起的，但味觉厌恶（如排斥反应所反映的）可能是由条件性恶心引起的。
The termsconditioned taste avoidance andconditioned taste aversion are often used interchangeably in the literature; however, considerable evidence indicates that they may represent different processes. Conditioned taste avoidance is measured by the amount that a rat consumes in a consumption test that includes both appetitive phases and consummatory phases of responding. However, conditioned taste aversion is more directly assessed with the taste reactivity test, which includes only the consummatory phase of responding. Rats display a conditioned taste aversion as conditioned rejection reactions (gapes, chin rubs, and paw treads) during an intraoral infusion of a nausea-paired flavored solution. Treatments that produce nausea are not necessary for the establishment of taste avoidance, but they are necessary for the establishment of taste aversion. Furthermore, treatments that alleviate nausea modulate neither the establishment nor the expression of taste avoidance, but they interfere with both the establishment and the expression of taste aversion. Considerable evidence exists indicating that these two measures are independent of one another. Taste avoidance may be motivated by conditioned fear rather than conditioned nausea, but taste aversion (as reflected by rejection reactions) may be motivated by conditioned nausea.
