当一对刺激匹配时，小猪学会在1个空间位置做出反应，当它们不匹配时，小猪学会在不同的空间位置做出反应。然后将所有的鸟转移到正交维度上的新刺激。对于正迁移组，匹配和不匹配刺激的正确位置保持不变。对于负迁移组，正确的位置被颠倒了。在实验1中，鸟训练与形状刺激和转移到色调刺激。显着的组间差异，尽管相当大的刺激特定的学习。在实验2中，当相同的鸟（实验1转移组的平衡）被转移到稳定间歇性刺激时，发现甚至更大的组间差异。显然，鸽子有一定的能力来代表与任意刺激相同和不同的概念（即，符号）。在匹配/奇怪转移任务和相同/不同任务之间已经做出的区分可能是程序性的而不是概念性的。
Pigeons learned to respond at 1 spatial position when a pair of stimuli matched and at a different spatial position when they mismatched. All birds were then transferred to novel stimuli on an orthogonal dimension. For the positive-transfer group, the correct positions for matching and mismatching stimuli remained as they were during training. For the negative-transfer group, the correct positions were reversed. In experiment 1, birds were trained with shape stimuli and transferred to hue stimuli. Significant group differences were found, despite considerable stimulus-specific learning. In experiment 2, when the same birds (counterbalanced for experiment 1 transfer group) were transferred to steady-intermittent stimuli, even larger group differences were found. Apparently, pigeons have some capacity for representing the concepts same and different with arbitrary stimuli (i.e., symbols). Distinctions that have been made between matching/oddity transfer tasks and same/different tasks may be procedural rather than conceptual.
