用大鼠进行的四个食欲巴甫洛夫条件反射实验检查了相对于化合物AY和BY之间的辨别，化合物AY和AX之间的辨别被解决的速率。在实验1和实验2中，这些辨别之前进行了训练，其中A和B被持续强化，X和Y被部分强化。与皮尔斯和霍尔（1980）的模型一致，结果表明，AY/AX判别比AY/BY判别更容易解决。在实验3和实验4中，辨别之前进行了特征阳性训练，其中AX和BY的试验表明食物，但X和Y的试验没有。与Macklett（1975）模型一致，结果表明AY/BY判别比AY/AX判别更容易解决。这些结果进行了讨论相对于一个混合模型的调节和注意。
Four appetitive Pavlovian conditioning experiments with rats examined the rate at which the discrimination between compounds AY and AX was solved relative to the discrimination between compounds AY and BY. In Experiments 1 and 2, these discriminations were preceded by training in which A and B were continuously reinforced and X and Y were partially reinforced. Consistent with the Pearce and Hall (1980) model, the results showed that the AY/AX discrimination was solved more readily than the AY/BY discrimination. In Experiments 3 and 4, the discriminations were preceded by feature-positive training in which trials with AX and BY signaled food but trials with X and Y did not. Consistent with the Mackintosh (1975) model, the results showed that the AY/BY discrimination was solved more readily than the AY/AX discrimination. These results are discussed with respect to a hybrid model of conditioning and attention.
