在 3 个实验中，大鼠预先接触复合风味 BX。然后通过评估 B 干扰另一种风味控制的厌恶或诱导盐需求后饮用盐溶液的倾向的能力来测试 B 的有效显着性。结果发现，在预暴露期间，BX 的呈现与单独的 X 的呈现交替时，B 的有效显着性得以保持。当 BX 作为同时化合物（实验 1）和串行化合物（X-->B；实验 2 和 3）时，情况都是如此；当系列化合物采用 B-->X 形式时，显着性无法保持（实验 2 和 3a）。有人认为，B 的显着性在预曝光期间会下降，但当 X 的呈现能够通过关联的 X-B 链接激活 B 的表示时，B 的显着性会恢复。
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.
