摘  要:目的:利用情绪Stroop任务测量海洛因依赖者是否存在对吸毒相关图片线索的注意偏向。方法:利用NeuroSCAN工作站STIM2编程,记录并比较研究组和对照组(各15例)对3类图片(包括中性、高唤起性、海洛因相关性)边框颜色的反应时及正确率。结果:海洛因相关图片反应时研究组长于对照组[(819.8±110.2)ms vs.(634.6±87.8)ms,P<0.01],高唤起性图片的反应时对照组长于研究组[(734.7±100.1)ms vs.(642.3±78.1)ms,P=0.01]。重复测量的方差分析发现存在刺激类别的主效应(F=31.63,P<0.01)以及组别和刺激类别的交互效应(F=11.31,P<0.01)。海洛因相关图片的反应时与吸毒时间呈正相关(r=0.41,P<0.05)。结论:海洛因依赖者存在对吸毒相关图片线索的注意偏向。Objective: To assess the reliability of heroin-specific attentionai bias across stimuli domains with the picture versions of the emotional Stroop task. Methods: With a NeuroSCAN workstation, an emotion Stroop task was used to compare the reaction time in addict and control group ( 15 cases in each group) to the picture border color of three categories including the neutral, evocative and heroin-related. Results: The addict group had longer reaction time to the heroin-related cues than the control group [ (819. 8 ± 110. 2) ms vs. (634. 6 ±87. 8) ms, P 〈0.01 ) ] . The control group had longer reaction time to the evocative cues [ (734.7 ± 100. 1 ) ms vs. (642. 3 ±78. 1) ms, P=0.01] .There was a significant main effect for stimulus type (F=31.63, P〈0.01), and a significant interaction effect between group and stimulus type ( F = 11.31, P 〈 0. 01 ) . The total months of heroin use were positively correlated with reaction time to heroin-related cues ( r =0. 41, P 〈0. 05 ) . Conclusion: Heroin addicts show significant attentional bias to heroin-related cues.
