海洛因戒断者的阈下情绪启动研究

摘要： 研究表明海洛因戒断者的情绪加工异常，但其阈下情绪加工是否异常尚无定论。本研究采用阈下情绪启动范式，考察其阈下情绪加工能力。结果：戒断组的反应时显著高于控制组；两组中，相比不一致、控制状态，一致状态反应时均显著最短；在戒断组中，不一致状态的反应时显著大于控制状态，负性图片的反应时显著大于正性图片，而在控制组中差异不显著。结论：戒断者存在阈下情绪启动效应，阈下情绪加工存在正性偏向，且能力弱于正常人。
Abstract: Literatures shows that heroin abstainers have abnormal emotional processing, but there has no conclusion for that whether their subliminal affective processing is abnormal or not. This study uses the subliminal affective priming paradigm to examine their subliminal affective processing capabilities. Results:(1) the response of the consistent trils was significantly the shortest in both groups; and the heroin abstainers have longer response time than control group (2) there was a positive bias in heroin abstainers. Conclusions: (1) There is a subliminal affective priming effect in heroin abstainers; (2) Due to the damage caused by long-term drug dependence, the subliminal affective processing is different from normal people. Tips：Enriches the theoretical basis for prevention of relapse in heroin abstainers.
