许多物种已经表现出学习抽象概念的能力。最近的研究表明，训练期间使用的刺激量对于受试者学习抽象概念起着至关重要的作用。随着训练集中可用刺激数量的增加，新颖组合的表现也会增加。集合大小的作用已经通过学习匹配和相同/不同的概念来探索，但没有通过学习差异的概念来探索。在本研究中，鸽子接受了非样本匹配任务的训练，初始训练集包含三种刺激，然后进行新刺激的转移测试。每次扩展后，通过学习和迁移，训练集逐渐加倍八倍。转移性能从最小集大小的机会水平 (50%) 提高到相当于两个最大训练集大小的渐近训练性能的水平 (384, 768)。通过与鸽子接受匹配规则训练的类似实验的结果进行比较，讨论了这种非匹配（差异）规则的渐进新颖刺激传递函数。
Many species have demonstrated the capacity to learn abstract concepts. Recent studies have shown that the quantity of stimuli used during training plays a critical role in how subjects learn abstract concepts. As the number of stimuli available in the training set increases, so too does performance on novel combinations. The role of set size has been explored with learning the concept of matching and same/different but not with learning the concept of difference. In the present study, pigeons were trained in a non-matching-to-sample task with an initial training set of three stimuli followed by transfer tests to novel stimuli. The training set was progressively doubled eight times with learning and transfer following each expansion. Transfer performance increased from chance level (50 %) at the smallest set size to a level equivalent to asymptotic training performance at the two largest training set sizes (384, 768). This progressive novel-stimulus transfer function of a non-matching (difference) rule is discussed in comparison with results from a similar experiment where pigeons were trained on a matching rule.
