【摘要】 目的探讨海洛因依赖者的选择性注意的功能。方法对25例海洛因依赖者和25例正常对照使用传统Stroop测验及其变式进行检测,并对结果进行对照分析。结果海洛因依赖者在传统Stroop测验的乙测验中总时间[(175.93±33.09)s]长于正常对照[(150.25±34.19)s],依赖者的正确数[(71.12±17.68)个]低于正常对照[(85.24±13.28)个],两组差异有显著性(P<0.05)。海洛因依赖者对海洛因相关词汇的反应时间[(1026.76±113.51)ms]明显比对中性词汇[(951.47±102.19)ms]和情绪词汇[(954.76±99.29)ms]的反应时间长,差异有显著性(P<0.05),而对中性词汇与情绪词汇反应时间差异无显著性(P>0.05)。依赖组对三种词汇的反应时间都比正常对照组长,差异有显著性(P<0.05)。结论海洛因依赖者注意分配和认知冲突的抑制能力明显受到损害,而且对海洛因相关刺激有明显的注意偏差。更多还原

【Abstract】 Objective To investigate the function of selective attention in patients with heroin dependence.Methods The function of selective attention with 25 heroin addicts and 25 normal controls was assessed by Stroop and modified Stroop task.Results Heroin addicts spent more time(175.93±33.09)s than the controls(150.25±34.19)s and heroin addicts have more errors than the controls. (P<0.05). The heroin addicts spent more time in responding to heroin-relevant words[(1026.76±113.51)ms] than to neutral words[(951.47±102.19)ms] or negative emotional related words[(954.76±99.29)ms]. The heroin addicts spent more time in responding to all the types of the words than the normal controls (P<0.05). Conclusion Heroin addicts have certain impairment in inhibitory mechanisms and allocation of attention, and there is obviously attentional bias to heroin-relevant words in patients with heroin dependence.更多还原
