目的:考察咀嚼口香糖对注意的影响. 方法:基于性别、特质性焦虑水平、嚼口香糖习惯大小(H/L)、以及实验时是否嚼糖(G/C).采用平衡组间设计将181名健康的大学生被试分为:实验时嚼糖且有习惯(GH)、实验时嚼糖但无习惯(GL).控制不嚼糖但有习惯(CH)、和控制不嚼糖且无习惯(CL)四个组,在实验室中进行连续操作测验(CPT-AX)和匹配搜索任务(CST)测验,用以评估持续性注意和选择性注意. 结果:除实验中咀嚼口香糖对被试成绩有积极影响外.咀嚼口香糖的经验对成绩显示了更重要影响. 结论:咀嚼口香糖对注意功能有积极影响,并且对口香糖的熟悉程度在此积极影响中起重要作用.“,”Purpose: To investigate the effect of gum chewing on the cognitive function of attention. Methods: Based on gum chewing habit, trait-anxiety variable, and different treatments (with or without gum chewing) during experiment,181 college students with good health were assigned to four groups GH (with chewing gum treatment and habit), GL (with chewing gum treatment, no habit), CH (no treatment,has habit) and CL (no treatment,no habit). Two attention tasks: Continuous Performance Test (CPT-AX) and Conjunctive Search Task (CST) were performed by all subjects in the laboratory.Results: Chewing gum during experiment had positive effect on attention performance, and the habit of gum chewing played an important role. Conclusion: Gum chewing had positive effect on attention performance, suggesting the effects mainly came from the familiarity of gum-chewing.rn
