本研究通过两个实验考察了训练后言语评价与巴甫洛夫-工具性迁移的关系。当一个单一的干扰器被使用时，延长训练的工具性反应增加转移，但降低贬值的影响。当使用多个工具性学习者时，学习者特定迁移和贬值效应受工具性训练量的影响较小。最后，虽然评价者贬值降低了巴甫洛夫条件反应和基线工具反应，但它对单评价者或评价者特异性转移没有影响。这些结果表明，迁移和联想器贬值可以反映联想学习的不同方面，联想学习的性质可以受到参数的影响，如训练量和使用多个联想器。
Relations between posttraining reinforcer devaluation and Pavlovian-instrumental transfer were examined in 2 experiments. When a single reinforcer was used, extended training of the instrumental response increased transfer but reduced devaluation effects. When multiple instrumental reinforcers were used, both reinforcer-specific transfer and devaluation effects were less influenced by the amount of instrumental training. Finally, although reinforcer devaluation decreased both Pavlovian conditioned responses and baseline instrumental responding, it had no effect on either single-reinforcer or reinforcer-specific transfer. These results indicate that transfer and reinforcer devaluation can reflect different aspects of associative learning and that the nature of associative learning can be influenced by parameters such as the amount of training and the use of multiple reinforcers.
