In 3 experiments, rats received preexposure to presentations of a compound flavor BX. The effective salience of B was then tested by assessing its ability to interfere with the aversion controlled by another flavor or the tendency to drink a saline solution after the induction of a salt need. It was found that the effective salience of B was maintained when during preexposure, presentations of BX alternated with presentations of X alone. This was true both when BX was presented as a simultaneous compound (Experiment 1) and as a serial compound (X-->B; Experiments 2 and 3); salience was not maintained when the serial compound took the form B-->X (Experiments 2 and 3a). It was argued that the salience of B declines during preexposure but is restored when presentations of X are able to activate the representation of B by way of the associative X-B link.
在3项实验中，大鼠预先接触复合味道BX。然后通过评估B干扰由另一种味道控制的厌恶反应的能力或诱导盐分需求后饮用盐溶液的倾向，来测试B的有效显著性。结果发现，当在预先接触期间，BX的呈现与单独呈现X交替进行时，B的有效显著性得以维持。当BX作为同时性复合物呈现时（实验1）以及作为序列性复合物呈现时（X→B；实验2和3）都是如此；当序列性复合物采取B→X的形式时（实验2和3a），显著性并未维持。有人认为，B的显著性在预先接触期间会下降，但当X的呈现能够通过X-B联想链接激活B的表征时，显著性会恢复。
