采用一致和不一致条件判别法研究了关联结构对目标导向行为的调节作用。刺激与一致性歧视的每个组成部分的结果相同，而不一致性歧视的一个组成部分的刺激与另一个组成部分的结果相同。人类，而不是老鼠，学习一致的歧视比不一致的歧视更快，作者将这种差异归因于结果-反应关联导致不一致歧视中的反应冲突。此外，响应是抵抗结果贬值后不一致，但不一致，培训，这表明人类和大鼠都采取了刺激反应策略，以解决不一致的歧视。
The associative structure mediating goal-directed action was investigated using congruent and incongruent conditional discriminations. The stimulus was the same as the outcome in each component of the congruent discriminations, whereas the stimulus of one component of the incongruent discriminations was the same as the outcome of the other component. Humans, but not rats, learned the congruent discrimination more rapidly than the incongruent discrimination, a difference that the authors attribute to the fact that outcome-response associations caused response conflict in the incongruent discrimination. Moreover, responding was resistant to outcome devaluation following incongruent, but not congruent, training, suggesting that both humans and rats adopted a stimulus-response strategy to resolve the incongruent discrimination.
