以前的研究人类情感学习，收购喜欢和不喜欢，提供的证据表明，灭绝训练不影响条件刺激（CS）效价的变化所索引的纸/铅笔评级。实验1（N = 32）调查这是否是一个伪像的CS效价评估，这是在测试会议之前和之后的培训。愉快的评级收集前/后培训测试，一半的参与者，在线培训期间。在厌恶性US（CS+）之前，CS的额定不愉快在采集过程中增加，在消退过程中减少，回到中性。然而，在以前的研究中，后消光纸/铅笔评级显示额定CS+不愉快的维护。实验2（N = 34）复制了这一发现的CS价，纸/铅笔和连续测量训练过程中使用的两个措施。目前的研究结果表明，以前的报告失败，发现灭绝的情感学习可能反映更新，而不是维护收购CS价在灭绝训练。(C)2003 Elsevier Science（美国）。All rights reserved.
Previous studies of human affective learning, the acquisition of likes and dislikes, provided evidence that extinction training does not affect changes in conditional stimulus (CS) valence as indexed by paper/pencil ratings. Experiment 1 (N = 32) investigated whether this is an artifact of the CS valence assessment, which is taken in test sessions before and after training. Pleasantness ratings were collected in pre/post training tests and, for half of the participants, on-line during training. Rated unpleasantness of the CS that preceded the aversive US (CS+) increased during acquisition and decreased during extinction back to neutral. However, as in previous studies, post extinction paper/pencil ratings revealed the maintenance of rated CS+ unpleasantness. Experiment 2 (N = 34) replicated this finding for two measures of CS valence, paper/pencil and the continuous measure used during training. The present results indicate that previous reports of failures to find extinction of affective learning may reflect renewal rather than maintenance of acquired CS valence across extinction training.
