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.
四项针对大鼠的经典性条件反射实验研究了相对于化合物AY与BY之间的辨别，化合物AY与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持续得到强化，而X和Y部分得到强化。与皮尔斯和霍尔（1980年）的模型一致，结果表明，AY/AX辨别比AY/BY辨别更容易解决。在实验3和实验4中，辨别之前进行了特征性阳性训练，其中AX和BY的试验表明有食物，但X和Y的试验则没有。与麦金托什（1975年）的模型一致，结果表明，AY/BY辨别比AY/AX辨别更容易解决。针对条件反射与注意力的混合模型对这些结果进行了讨论。
