Recent research into evaluative conditioning (EC) shows that information about the relationship between the conditioned and unconditioned stimuli can exert strong effects on the size and direction of the EC effect. Additionally, the co-occurrence of these stimuli seems to exert an orthogonal effect on evaluations. This finding has been interpreted as support for two independent types of EC effects. However, previous research devoted to this question relied on aggregated evaluative measures, allowing for alternative interpretations. In four experiments, we developed and validated a multinomial processing tree model that distinguishes effects of the pairings from effects of the meaning of the pairings. Our findings suggest that two independent EC effects contribute to overall evaluative change in a relational EC paradigm. The model that we developed offers a helpful method for future research in that it allows for an assessment of the effects of manipulations on processes rather than overall performance on an evaluative measure.
最近关于评价条件作用（EC）的研究表明，关于条件刺激和非条件刺激之间关系的信息可以对 EC 效应的大小和方向产生强烈影响。此外，这些刺激的同时出现似乎对评价产生了正交效应。这一发现被解释为对两种独立类型的 EC 效应的支持。然而，之前关于这个问题的研究依赖于聚合的评价测量，这允许了替代的解释。在四个实验中，我们开发并验证了一个多项式处理树模型，该模型区分了配对的影响和配对意义的影响。我们的研究结果表明，在关系型 EC 范式中，两种独立的 EC 效应有助于整体评价的变化。我们开发的模型为未来的研究提供了一种有用的方法，因为它允许评估对过程的影响，而不是对评价测量的整体表现。
