在2个实验中，研究了刺激物在信号试验结果中的作用与对其的注意力之间的关系。在实验1中，在鸽子中使用自动整形显示了维度内-维度外移位效应。在实验2中，鸽子进行了训练与biconnumbers歧视，使用刺激化合物不同的3个维度（颜色，方向和位置），其中2个是相关的解决方案的歧视，其中1个是无关的。如果相同的刺激维度与两种歧视的解决方案相关，则随后的双认知度歧视的获得比先前不相关的歧视变得相关更快。这些结果表明，对刺激的关注程度取决于其与歧视解决方案的相关性，而不是其与奖励的相关性。
In 2 experiments, the relationship between the role of a stimulus in signaling trial outcome and the attention paid to it was investigated. In Experiment 1, an intradimensional-extradimensional shift effect was shown in pigeons using autoshaping. In Experiment 2, pigeons were trained with a biconditional discrimination, using stimulus compounds varying on 3 dimensions (color, orientation, and position), 2 of which were relevant to the solution of the discrimination, and 1 of which was irrelevant. Acquisition of a subsequent biconditional discrimination was more rapid if the same stimulus dimensions were relevant to the solution of both discriminations than if a previously irrelevant discrimination became relevant. These results indicate that the amount of attention paid to a stimulus is determined by its relevance to the solution of a discrimination, and not by its correlation with reward.
