Transitive inference (TI) has been studied in humans and several animals such as rats, pigeons and fishes. Using different methods for training premises it has been shown that a non-trained relation between stimuli can be stablished, so that if A > B > C > D > E, then B > D. Despite the widely reported cases of TI, the specific mechanisms underlying this phenomenon remain under discussion. In the present experiment pigeons were trained in a TI procedure with four premises. After being exposed to all premises, the pigeons showed a consistent preference for B over D during the test. After overtraining C+D- alone, B was still preferred over D. However, the expected pattern of training performance (referred to as serial position effect) was distorted, whereas TI remained unaltered. The results are discussed regarding value transfer and reinforcement contingencies as possible mechanisms. We conclude that reinforcement contingencies can affect training performance without altering TI.
传递性推理（TI）已在人类以及大鼠、鸽子和鱼类等多种动物中得到研究。使用不同的方法训练前提条件表明，可以建立刺激之间未经过训练的关系，这样如果A > B > C > D > E，那么B > D。尽管有大量关于传递性推理的报道，但这种现象背后的具体机制仍在讨论中。在本实验中，鸽子接受了包含四个前提条件的传递性推理程序训练。在接触所有前提条件后，鸽子在测试中始终表现出对B的偏好超过D。单独对C+D-进行过度训练后，对B的偏好仍然超过D。然而，预期的训练表现模式（称为系列位置效应）被扭曲了，而传递性推理保持不变。讨论了价值转移和强化意外情况作为可能机制的结果。我们得出结论，强化意外情况可以影响训练表现而不改变传递性推理。
