六名正常能力的成年人首先通过配对样本训练，在两个预期等价课程中分别学习了三个条件关系，这些训练以数字作为条件（样本）和判别（比较）刺激。然后，在每个预期班级中，一个经过训练的条件关系被置于语境刺激的控制下，两个听写的无意义音节。测试表现表明出现了未经训练的条件关系，因此出现了两个等价类，这是基于上下文刺激的条件。这些测试涉及未经训练的情境刺激和条件关系中的刺激的组合，表明情境刺激独立地控制条件关系，而不是在训练中与样本和比较形成复合刺激。接下来，通过匹配样本训练和测试，将两个新的图形与每个原始的口授上下文刺激等效。在随后的测试中，所有受试者都表现出对未经训练的条件关系的条件控制从原始的听觉环境刺激转移到等效的视觉刺激。这些结果进一步支持了上下文刺激对等价类条件关系施加真正条件控制的结论，而不仅仅是复合刺激的组成部分。
Six normally capable adults first learned three conditional relations in each of two prospective equivalence classes via match-to-sample training with figures as conditional (sample) and discriminative (comparison) stimuli. Then one trained conditional relation in each prospective class was brought under the control of contextual stimuli, two dictated nonsense syllables. Test performances indicated the emergence of untrained conditional relations, and therefore two equivalence classes, that were conditional on the contextual stimuli. These tests involved untrained combinations of contextual stimuli and stimuli in conditional relations, suggesting that the contextual stimuli functioned independently to control conditional relations rather than forming compound stimuli with samples and comparisons in training. Next, two novel figures were made equivalent to each of the original dictated contextual stimuli by match-to-sample training and testing. On subsequent tests, all subjects demonstrated transfer of conditional control of untrained conditional relations from the original auditory contextual stimuli to equivalent visual stimuli. These outcomes further supported the conclusion that the contextual stimuli exerted true conditional control over conditional relations in the equivalence classes and were not merely elements of compound stimuli.
