评价性条件反射是指对刺激物（条件刺激）喜好的改变。CS）的结果，从配对的刺激与其他积极或消极的刺激（无条件刺激。在主样本中纳入的总共214项研究中，平均EC效应为d = 52。95%置信区间为466-582。根据随机效应模型估计，效应量中约70%的方差可归因于真实的系统变异而不是抽样误差。进行调节分析以部分解释这种变异，既作为程序实施的具体方面的功能，又作为CS和US之间关系的抽象方面的功能在一系列其他发现中。高应变意识的EC效应强于低应变意识的EC效应，阈上的EC效应强于阈下的EC效应，获得后的EC效应强于消退后的EC效应，自我报告的EC效应强于许多内隐测量的EC效应。这些结果结合EC的程序边界条件和有关EC背后心理过程的理论解释进行了讨论
This article presents a meta-analysis of research on evaluative conditioning (EC), defined as a change in the liking of a stimulus (conditioned stimulus. CS) that results from pairing that stimulus with other positive or negative stimuli (unconditioned stimulus. US) Across a total of 214 studies included in the main sample, the mean EC effect was d = 52. with a 95% confidence interval of 466-582 As estimated from a random-effects model, about 70% of the variance in effect sizes were attributable to true systematic variation rather than sampling error Moderator analyses were conducted to partially explain this variation, both as a function of concrete aspects of the procedural implementation and as a function of the abstract aspects of the relation between CS and US Among a range of other findings. EC effects were stronger for high than for low contingency awareness, for supraliminal than for subliminal US presentation for postacquisition than for postextinction effects, and for self-report than lot implicit measures These findings are discussed with regard to the procedural boundary conditions of EC and theoretical accounts about the mental processes underlying EC
