大鼠接受暴露于3种风味化合物，AX和BX，交替呈现，CX，在单独的试验块中呈现。该处理将使B有效地比C更突出的假设以3种方式进行检验。实验一表明，B诱发的非条件反应强于C诱发的非条件反应。实验2表明，当用作感觉预处理程序中的增强剂时，B比C更有效。实验3表明，在味觉厌恶条件反射中，B作为条件刺激比C更容易被学习。交替预暴露于2个相似的刺激可能会保护他们的显着性的损失，通常产生的非强化暴露于刺激的显着性。
Rats received exposure to 3 flavor compounds, AX and BX, presented in alternation, and CX, presented on a separate block of trials. The hypothesis that this treatment would leave B effectively more salient than C was tested in 3 ways. Experiment 1 showed that the unconditioned response evoked by B was stronger than that evoked by C. Experiment 2 showed that B was more effective than C when used as a reinforcer in a sensory preconditioning procedure. Experiment 3 showed that B was learned about more readily than C as a conditioned stimulus in flavor aversion conditioning. Alternating preexposure to 2 similar stimuli may protect their distinctive features from the loss of salience normally produced by nonreinforced exposure to a stimulus.
