Abstract
The present study aimed to assess the effect of transcranial direct current stimulation (tDCS) on the visual attention and response control of chess players in Mahabad city. Visual attention and response control are considered effective elements for the success of chess players, and there is evidence that the cathodic stimulation of the Fp2 and C3 anode can be effective in increasing visual attention and response control. Therefore, 20 people (12 girls and 8 boys, 15 to 35 years old) of the chess board chess players who competed at both intermediate and advanced levels were selected by convenience sampling method and then randomly assigned to intervention and control groups. First, both groups performed the test (IVA-2) to register the pre-test, and then the intervention group was subjected to 20 minutes of anodic C3 and cathodic Fp2 stimulation with a current intensity of 1.5 milliamperes in 15 sessions; But no intervention was done for the control group. Finally, the IVA-2 post-test was re-implemented to measure and check the visual attention and response control of chess players after the intervention. The findings obtained using multivariate analysis of covariance (MANCOVA) showed that TDCS had a significant effect on the improvement of visual attention and response control of athletes (P<0/05). According to the results of this research, it can be said that one of the effective methods to improve the visual attention and response control of chess players is transcranial brain stimulation (tDCS).
