Palatabilities and also satieties are assumption-loaded abstractions from the observable momentary causal relationships between eating or drinking and the situations in which it occurs. Palatability is neither in the food nor in the ingestive movements. Relative preference can vary with context, contrary to the usual concept of stable palatability. Satieties exemplify this, for they can be food-specific, i.e. ingestion-induced suppression of appetite may alter the supposed palatability hierarchy.
适口性和饱腹感都是基于假设的抽象概念，它们源于饮食行为与其发生情境之间可观察到的瞬间因果关系。适口性既不存在于食物中，也不存在于摄食动作中。与适口性稳定的通常概念相反，相对偏好会因情境而异。饱腹感就是例证，因为它们可能具有食物特异性，即摄食引起的食欲抑制可能会改变假定的适口性等级。
