Many experiments on the role of learning in the amount eaten at a distinctive test meal have been claimed to observe "conditioned satiety." None published from outside this author's group has used either the necessary design of the contingencies to be learnt or the measurements that distinguish a sating effect from other loss of interest in food. One experiment has just been published without an adequate design but giving the best evidence yet from another group for the conditioning of sensory-gastric satiety; yet the authors conclude for changes in sensory preference with no learnt gastric involvement in the meal size response. To encourage correct use of the demonstrations in rats, monkeys and people of conditioned satiety and its mechanism, this paper briefly reviews publications that attribute control of meal size to learnt satiety.
许多关于学习在特定测试餐进食量中所起作用的实验都声称观察到了“条件性饱腹感”。除了本文作者所在团队之外，其他地方发表的研究都没有采用学习所需的意外情况设计，也没有使用能够区分饱腹感效应与对食物其他兴趣丧失的测量方法。刚刚发表的一项实验虽然设计不够完善，但却给出了另一组关于感觉性胃饱腹感条件作用的最佳证据；然而，作者得出的结论却是感觉偏好发生了变化，而在进食量反应中胃并没有参与学习过程。为了鼓励正确运用在大鼠、猴子和人类身上关于条件性饱腹感及其机制的论证，本文简要回顾了那些将进食量控制归因于习得性饱腹感的出版物。
