Abstract

Purpose : Study on the effects of attention(working memory) for normal adults by applying transcranial Direct Current Stimulation(tDCS). Methods : There are two groups of 10 random people aged between 20 to 30, one is an experimental group(stimulation) and the other is a comparison group(simulate stimulation). For the 1st da y, pre-stimulation test is executed, and for the 2nd day to the 4th day, tDCS is applied stimulated both on the right prefrontal lobe and the left occipital lobe through the electrode. The stimulation lasts for 15 minutes with voltage power of 1mA for each day. The post-stimulation test is executed on the day of 5th. In this paper, a FAIR attention test is used for measuring the attention. Results : As the result of the experiment, there are significant gaps both on the value of P, the ability of selective attention, and the value of C, the consistent ability after the stimulation on right prefrontal and left occipital lobe. And there is no significant gap on the value Q, the quality(Control). However, all the P, Q, and C values are increased according to the average value between the pre-stimulation test and the post-stimulation. Conclusion : Finally, ability of selective attention and self-control, and consistent attention is progressed by applying the tDCS to the normal people.
