在鸽子中训练具有共同延迟或食物强化概率的感知不同的相关刺激类对。然后，将不同的选择反应训练到每对中的1个成分类别。在选择测试中，每对中未经训练的班级引起的反应与接受选择训练的班级相同。在第三个实验中，2个班的强化延迟分别为1 S和15 S，另外2个班的强化概率分别为0.1和0.9。然后，1个选择反应被强化到先前与较好的强化条件(例如，1-S延迟或1的概率)相关联的类别，而不同的反应被强化到先前与较差的强化条件(0.1概率或0-S延迟)相关联的类别。对所有类别的测试表明，分类是基于相对强化或享乐值，而不是基于强化的参数细节。
Training associated pairs of perceptually dissimilar stimulus classes with a common delay or probability of food reinforcement in pigeons. Then, different choice responses were trained to 1 component class in each pair. In a choice test, the untrained class in each pair occasioned the same response as did the choice-trained class. In a 3rd experiment, 2 classes had reinforcement delays of 1 s and 15 s, respectively, and 2 other classes had reinforcement probabilities of 0.1 and 0.9. Then, 1 choice response was reinforced to a class previously associated with a better condition of reinforcement (e.g., 1-s delay or 1.0 probability), and a different response was reinforced to a class previously associated with a worse condition of reinforcement (0.1 probability or 0-s delay). Testing with all classes suggested that categorization was based on the relative reinforcement or hedonic value and not on the parametric details of reinforcement.
