Two experiments were conducted to examine whether the resistance to extinction obtained in evaluative conditioning (EC) studies implies that EC is a qualitatively distinct form of classical conditioning (Baeyens, Eelen, & Crombez, 1995 a) or whether it is the result of an nonassociative artefact ( Field & Davey, 1997 , 1998 , 1999 ). Both experiments included between-subjects control groups in addition to standard within-subjects control conditions. In Experiment 1, only verbal ratings were measured in order to evaluate the effect of postacquisition CS-only exposures on EC whereas in Experiment 2, verbal ratings and postextinction priming effects were measured. The results showed that the EC effects are demonstrable in a between-subjects design and that the extinction procedure did not have any influence on the acquired evaluative value of CSs regardless of whether the verbal ratings or the priming effects were used as dependent variables. The present results provide evidence that EC is resistant to extinction and suggest an interpretation of EC as a qualitatively distinct form of associative learning.
两项实验旨在检验评价性条件作用（EC）研究中获得的抗消退是否意味着 EC 是一种与经典条件作用（Classical Conditioning）本质不同的形式（Baeyens、Eelen 和 Crombez，1995a），还是非联想性人为因素的结果（Field 和 Davey，1997、1998、1999）。这两个实验都包括了组间控制组，除了标准的组内控制条件外。在实验 1 中，仅测量了口头评价，以评估后获得的 CS 仅暴露对 EC 的影响，而在实验 2 中，测量了口头评价和后消退启动效应。结果表明，EC 效应在组间设计中是明显的，无论使用口头评价还是启动效应作为因变量，消退程序都不会对 CSs 的获得的评价价值产生任何影响。本研究结果提供了证据表明 EC 具有抗消退性，并暗示 EC 可以被解释为一种与经典条件作用本质不同的联想学习形式。
