| 目的 探讨重复经颅直流电刺激与舒尔特方格训练对健康大学生注意力的提升效果。方法 采用两因素混合实验设计（时间×组别），选择60名健康大学生随机分为刺激组（被试接受重复经颅直流电刺激，n=21）、训练组（接受舒尔特方格注意力训练，n=21）、对照组（予假刺激干预，n=18）。3组被试均完成了为期4周共计12次干预，采用简单数字舒尔特方格任务、注意转换任务、色词Stroop任务动态评估被试的注意力提升效果。结果 刺激组与训练组被试在简单数字舒尔特方格任务和注意转换任务中的成绩均较基线水平提升（P均<0.05），其中刺激组成绩于第1周发生显著变化，而训练组则在第2周以后才出现有效注意力提升；3组色词Stroop任务成绩均未发生变化。结论 长期舒尔特方格注意力训练与经颅直流电刺激均能促进健康大学生的注意力提升，而经颅直流电刺激下注意力的提升发生更早。 |

| Abstract: |
| Objective To explore the enhancing effect of repetitive transcranial direct current stimulation (tDCS) and Schulte grid training on attention of healthy undergraduates. Methods A two-factor mixed experimental design (time×group) was adopted in this study. Sixty healthy undergraduates were randomly assigned to anodal group (receiving repetitive tDCS intervention, n=21), training group (receiving Schulte grid training, n=21) and control group (receiving sham stimulation, n=18). The participants in the three groups received a total of 12 interventions over a 4-week period. Simple digital Schulte grid task, shifting attention task and color-word Stroop task were used to assess the attention enhancing effect. Results In the anodal group and training group, the scores of the participants in simple digital Schulte grid task and shifting attention task were significantly higher than the baseline (all P<0.05); significant changes in the stimulation group were observed in the first week, while the training group showed effective enhancements after the second weeks. There was no significant change in the score of Stroop task in the three groups. Conclusion Both long-term Schulte grid attention training and tDCS can enhance the attention of healthy undergraduates, and the enhancement on attention induced by tDCS is earlier. |
