Three experiments, using a total of 13 pigeons, examined the stimulus control acquired by the separate components of a compound visual stimulus transilluminating the pecking key. Experiment I measured the control acquired by components of compound discriminative stimuli used in discrimination training. Experiment II sought to demonstrate the effect of pretraining a single stimulus discrimination on control acquired by each component in a compound stimulus discrimination. It also investigated the effect of training the compound stimulus discrimination before the single stimulus discrimination. Experiment III sought a continuous stimulus control function when pretraining stimulus intensities were varied. The results suggest that the extent to which a bird "pays attention" to a stimulus, defined in terms of the degree of stimulus control acquired by that stimulus, is determined by how well it previously learned to discriminate that stimulus from other stimuli.
三项实验共使用了13只鸽子，研究了透过啄击键的复合视觉刺激的各个组成部分所获得的刺激控制。实验I测量了辨别训练中使用的复合辨别刺激的各个组成部分所获得的控制。实验II试图证明对单一刺激辨别进行预训练对复合刺激辨别中每个组成部分所获得的控制的影响。它还研究了在单一刺激辨别之前训练复合刺激辨别的效果。实验III在预训练刺激强度变化时寻求连续的刺激控制函数。结果表明，鸟类对刺激的“关注”程度（根据该刺激所获得的刺激控制程度来定义）取决于它之前将该刺激与其他刺激区分开的学习程度。
