本研究试图（a）测试是否自主（即，皮肤电）和评价性条件反射可以差异地建立到言语CS，以及（B）消退程序是否可以可靠地减弱差异条件评价性反应。30名大学生经历了10分钟的适应期，随后是三个连续的条件反射阶段：习惯化，收购和灭绝。条件反射涉及参与者在计算机显示器上观看两个半随机呈现的单词。在收购过程中，一个字（CS+）是可靠的配对12倍的UCS（图片刺激描绘身体残害），而其余的字（CS-）提出了12次，可靠地其次是中性图片（无生命的共同对象）。正如预测的那样，在收购过程中的皮肤电和评价反应的CS+相比，CS-在灭绝，参与者继续评价CS+更恶心相对于CS-，而痛苦和恐惧相关的情绪评级衰减灭绝试验。这些研究结果的影响，在特定的焦虑症厌恶为基础的评价反应的可修改性进行了讨论。(c)2006爱思唯尔有限公司保留所有权利。
The present study sought to (a) test whether autonomic (i.e., electrodermal) and evaluative conditioning can be differentially established to verbal CSs, and (b) whether extinction procedures can reliably attenuate differential conditioned evaluative responding. Thirty undergraduates underwent a 10-min adaptation period followed by three consecutive conditioning phases: habituation, acquisition, and extinction. Conditioning involved participants viewing two semi-randomly presented words on a computer monitor. During acquisition, one word (CS+) was reliably paired 12 times with the UCS (pictorial stimuli depicting bodily mutilation), whereas the remaining word (CS-) was presented 12 times and reliably followed by neutral pictures (inanimate common objects). As predicted, electrodermal and evaluative responses during acquisition were of larger magnitude to the CS+ compared to the CS- During extinction, participants continued to evaluate the CS+ as more disgusting relative to the CS-, whereas distress and fear-related emotional ratings attenuated across extinction trials. The implications of these findings for the modifiability of disgust-based evaluative responses in specific anxiety disorders will be discussed. (c) 2006 Elsevier Ltd. All rights reserved.
