摘要

当涉及到同时处理两个任务时,信息处理能力通常低于标准,是不可取的。因此,本初步研究旨在探讨经颅直流电刺激(tDCS)对背外侧前额叶皮层(DLPFC)执行双重任务的影响。选取平均年龄(25.2±2.43)岁的学生26名,随机分为实验组和假手术组。所有被试在tDCS前后进行了双重任务情境下的Stroop效应测试。该测试包括100和900毫秒刺激之间的两个间隔。混合方差分析结果表明,实验刺激组的平均第二反应时间(在具有一致和不一致刺激的双重任务中)在tDCS后显著缩短。因此,可以认为DLPFC的tDCS提高了信息处理速度和注意能力,从而降低了心理不应期的影响。

The effect of transcranial direct current stimulation of dorsolateral prefrontal cortex on performing a sequential dual task: a randomized experimental study.

When it comes to simultaneous processing of two tasks, information processing capacity is usually below par and not desirable. Therefore, this preliminary study aimed to investigate the effect of transcranial direct-current stimulation (tDCS) of dorsolateral prefrontal cortex (DLPFC) on performing dual tasks. Twenty-six students (average age 25.2 ± 2.43 years) were selected and then randomly divided into experimental and sham groups. All of the participants conducted the Stroop effect test in a dual task situation before and after the tDCS. This test included two intervals between the stimuli of 100 and 900 ms. The results of mixed-ANOVA showed that the average second reaction time of the experimental stimulated group was reduced (in both dual tasks with congruent and incongruent stimuli) significantly after the tDCS. Therefore, it can be stated that the tDCS of the DLPFC increases the information processing speed and the capacity of attention and, as a result, decreases the effect of the psychological refractory period.
