摘要在恐惧条件反射过程中获得的负条件刺激(CS)效价可能会增加恐惧的复发，并且很难消除，因为它消退得很慢，而且对无条件刺激(US)呈现将停止的指令没有反应。我们研究了以CS价位为目标的指令是否会更有效。在实验1中，一个人的形象(CS+)与厌恶的美国配对，而另一个人的形象(CS−)单独呈现。获得后，受试者被给予关于CS+POSER的正面信息和关于CS−POSER的负面信息。指令逆转了在获取过程中存在的不同CS价态的模式，并消除了不同的皮肤电反应。在实验2中，我们通过提供关于CS+的正/负信息和关于CS−的中性信息来比较正向和负向CS重估。正向重估后，差化价被去除，差异性皮肤反应保持不变。在负重估后，差化价得到加强，差异性皮肤反应被消除。出乎意料的是，这些说明并没有影响差异性皮肤电反应的恢复。
ABSTRACT Negative conditional stimulus (CS) valence acquired during fear conditioning may enhance fear relapse and is difficult to remove as it extinguishes slowly and does not respond to the instruction that unconditional stimulus (US) presentations will cease. We examined whether instructions targeting CS valence would be more effective. In Experiment 1, an image of one person (CS+) was paired with an aversive US, while another (CS−) was presented alone. After acquisition, participants were given positive information about the CS+ poser and negative information about the CS− poser. Instructions reversed the pattern of differential CS valence present during acquisition and eliminated differential electrodermal responding. In Experiment 2, we compared positive and negative CS revaluation by providing positive/negative information about the CS+ and neutral information about CS−. After positive revaluation, differential valence was removed and differential electrodermal responding remained intact. After negative revaluation, differential valence was strengthened and differential electrodermal responding was eliminated. Unexpectedly, the instructions did not affect the reinstatement of differential electrodermal responding.
