摄入蔗糖的动机的改变可以通过测量口腔运动和躯体反应的数量和类型来量化（即，味觉反应性[TR]）。在2个实验中，大鼠口内输注蔗糖与LiCl注射配对进行几次试验，或者在注射后30分钟内每5分钟注射一次LiCl并输注蔗糖（数据来自Spector，Breslin和Grill，1988）。在这两个实验中，摄食TR反应下降，而厌恶TR反应增加试验。包括摄食和厌恶类别的个体反应组分遵循相同的增加或减少趋势，但以不同的速率变化，作为试验或暴露次数的函数。总的来说，一系列的反应成分可以投射到一个单一的一维尺度的适口性，以捕捉从接受到拒绝的动机状态。
Alterations in the motivation to ingest sucrose can be quantified by measuring the number and type of oral motor and somatic responses (i.e., taste reactivity [TR]) that are elicited by sucrose. In 2 experiments, rats had intraorally infused sucrose paired with LiCl injections for several trials, or they were injected with LiCl and had sucrose infused every 5 min during the 30-min postinjection period (data from Spector, Breslin, & Grill, 1988). In both experiments, ingestive TR responses decreased, whereas aversive TR responses increased over trials. Individual response components that comprise the ingestive and aversive categories followed the same trends of increase or decrease but changed at different rates as a function of number of trials or exposures. Overall, the array of response components could be projected onto a single unidimensional scale of palatability to capture the motivational states that ranged from acceptance to rejection.
