饮酒对大学生注意网络功能的影响

The Influence of Alcohol on College Students' Attention Network

[目的]探讨中等剂量的酒精摄入对大学生注意网络及各子系统的影响。[方法]研究对象为60名大学生,均为社会性饮酒者,采用抽签的方式随机分配到饮酒组(30人)和对照组(30人)。运用注意网络测试分别从警觉、定向和执行控制三个维度对注意网络进行测量。[结果]与对照组相比,饮酒组注意网络中警觉效率、执行控制效率和反应时间均受到明显影响,差异有统计学意义(P<0.05或P<0.01);定向效率和正确率未受到明显的影响(P>0.05)。[结论]大学生社会饮酒者摄入中等剂量的酒精后注意网络出现损伤,酒精对注意网络的各子系统影响有差异。

[Objective] To explore the moderate dose of alcohol intake＇s influence on each dimension of attention of college students.[Methods] Subjects were 60 university students who were social drinkers and they were allocated randomly by a lottery method to drinking group （N=30） and control group （N=30）. The alerting task, orienting task and executive control task were employed to measure attention network from three aspects respectively. [Results] Drinking group was compared with the control group, in three dimensions of attention network. The differences were statistically significant in the reaction time and the efficiency of alerting and executive control （P〈0.05 or P〈0.01）. There is no statistical significance in the efficiency of orienting and the rate of accuracy （P〉0.05）. [Conclusion] The attention networks of college social drinkers are damaged after moderate alcohol intake, and there are differences between the damage on three dimensions of attention network.
