Evaluative conditioning (EC) refers to changes in the liking of an affectively neutral stimulus (the conditioned stimulus, or CS) following the pairing of that stimulus with another stimulus of affective value (the unconditioned stimulus, or US). In 3 experiments, the authors assessed contingency awareness, that is, awareness of the CS-US associations, by relying on participants' responses to individual items rather than using a global method of assessment. They found that EC emerged on contingency aware CSs only. Of note, whether the CSs were evaluated explicitly (Experiments 1 and 2) or implicitly (Experiment 3) did not make a difference. This pattern supports the idea that awareness of the CS-US associations may be required for valence acquisition via EC.
评价性条件作用（EC）是指在一个情感中性刺激（条件刺激，或CS）与另一个具有情感价值的刺激（无条件刺激，或US）配对后，该中性刺激的喜好度发生变化。在3项实验中，作者通过依赖参与者对单个项目的反应，而非使用整体评估方法，来评估偶然性意识，即对CS-US关联的意识。他们发现，评价性条件作用仅出现在具有偶然性意识的条件刺激上。值得注意的是，条件刺激是被明确评价（实验1和2）还是被隐含评价（实验3）并无差异。这一模式支持了这样一种观点，即通过评价性条件作用获得效价可能需要对CS-US关联有所意识。
