【摘要】：情绪障碍治疗的关键在于消退条件性恐惧记忆,研究证明基于记忆再巩固的提取-消退范式能有效消除或改写原有的恐惧记忆。本研究将提取-消退范式应用到更复杂的恐惧记忆中,采用多感官复合刺激(声音+图片)作为条件刺激,以皮电反应作为恐惧反应指标,考察采用单个线索(声音或图片)、复合线索(声音+图片)进行提取-消退对条件性恐惧记忆的消退效果有何差异。结果表明:声音线索提取-消退组出现了自发恢复和重建效应,图片提取-消退组只出现了重建效应,复合刺激提取-消退组未出现自发恢复和重建效应。说明由复合刺激线索引发的条件性恐惧,采用复合刺激中的单个较强线索或原有完整线索进行提取-消退,对恐惧记忆的消退效果最好。
[Abstract]:The key to the treatment of emotional disorders lies in the regression of conditional fear memory. It is proved that the abstraction-regression paradigm based on memory re-consolidation can effectively eliminate or rewrite the original fear memory. In this study, the extract-regression paradigm was applied to the more complex fear memory, and the multisensory compound stimulus (sound picture) was used as the conditioned stimulus, and the electrodermal response was used as the fear response index. In this study, we investigated the difference of the regression effect of conditional fear memory by using single cues (voice or picture) and compound cues (sound images). The results showed that the spontaneous recovery and reconstruction effect appeared in the audio cue-regression group, only the reconstruction effect in the picture-subtractive group, and no spontaneous recovery and reconstruction effect in the compound stimulus-subtractive group. The results show that the conditional fear caused by the complex stimulus leads to the best effect on the regression of fear memory by using a single stronger clue or the original complete clue in the compound stimulus to extract and subside.
