Effectiveness of Trans- Cranial Electrochemical Stimulation)TDCS( on Improving Visual Attention in High School Students

The purpose of this study was to determine the effect of trans- cranial direct electrical stimulation (TDCS) on improving visual attention in high school students. This quasi-experimental research was carried out in a pre-test and post-test design with a control group. The statistical population was all the high school students in district 2 of Tehran city the enrolled in the academic year of 1395-1396. Sampling was carried out voluntarily. Thus, among the high schools of Tehran 2nd district, 3 schools were randomly selected. In the next step, calls were made on the bulletin boards of these schools. Then volunteers were invited. The data were collected by questionnaire of general mental health(SCL-25)and Tools-Pieron test.At first, the questionnaires were performed as pre-test and then, a direct trans-cranial electric stimulation )TDCS( of the brain was performed for the experimental group. Subsequent invasive brain electrochemical stimulation was performed for the experimental group. At the end of the course, participants were re-evaluated using the Toulouse-Pyrin Precision Test, which comprised post-test data. Covariance test was used to evaluate the difference of responses before and after electrical stimulation and analysis of data. The results of the post-intervention study showed a significant difference between the experimental and control groups in the visual attention variable. It can be said that trans- cranial direct electrical stimulation)TDCS( is effective in improving visual attention of high school students.
