双线索竞争条件下海洛因戒除者的前注意偏向特性

The Preattentional Bias of Heroin Abstainers under Two-cues Competition Condition

以33名男性海洛因戒除者为被试,采用分离的stroop范式探讨了海洛因戒除者在双线索竞争条件下的前注意选择特性。结果发现,在早期注意加工阶段,海洛因戒除者对海洛因相关线索表现出优先选择的倾向;长期滥用海洛因对戒除者的抗干扰能力具有一定程度的损伤。该研究为解释现实生活中戒除者对海洛因相关线索的快速觉察现象提供了实验证据。

The study estimated the preattentional bias toward heroin-related cues of heroin abstainers by separated paradigm of the emotionstroop under two-cue competition condition. The results indicated that： （1） It appeared that heroin abstainers showed attention bias to heroin-related cues in early attentional process phase; （2） Long time heroin abuse damaged the ability of anti-jamming in a certain degree. The study had provided experimental evidence for explaining abstainers＇ quick detecting bias to heroin-related cues in real-life.
