Associative cue competition treatments like blocking reduce behavioral control by a target cue at later test. Interestingly, Pavlovian conditioning experiments have documented that two cue competition treatments can counteract when they are administered together, resulting in less competition with and greater behavioral control by a target CS (for a review, see Wheeler & Miller, 2008). The present experiments confirmed this observation in a human contingency learning procedure. In two human contingency learning experiments, participants received Phase 1 training of two excitatory cues (C and D, A and D, or A and B) followed by Phase 2 ABX + trials. We observed greater ratings to cue X at test by participants who received previous training of both A and B than by participants who received Phase 1 training of A alone. Thus, two blocking cues counteracted in human contingency learning.

人类偶然性学习中的两个阻碍线索相互抵消

诸如阻塞之类的联合提示竞争处理会在以后的测试中降低目标提示的行为控制。有趣的是,巴甫洛夫式的条件实验已经证明,两种提示竞争治疗同时使用可以抵消效果,从而减少与目标CS的竞争并增强行为控制(有关综述,请参见Wheeler&Miller,2008)。本实验在人类偶然性学习程序中证实了这一观察结果。在两个人类偶然性学习实验中,参与者接受了两个兴奋性提示(C和D,A和D或A和B)的第1阶段训练,然后进行了第2 ABX +试验。我们观察到接受过A和B培训的参与者在测试中对提示X的评分要高于接受单独A阶段1培训的参与者。从而,
