Abstract

The current study aimed to investigate the effect of transcranial direct current stimulus on selective attention in dual task paradigm. By semi-experimental method 28 students of Shahid Chamran University of Ahvaz were recruited (mean age: 25.32±2.46) by at available sampling method and assigned into experimental and Sham equally groups. Participants were asked to perform dual task test of Stroop’s effect  before and after transcranial stimulus. The test included four stimulus onset synchronized of 50, 100, 300 and 900 thousandth of a second between two stimuli in three Stroop’s effect conditions with dual task paradigm. The results of the mix analysis of variance revealed that the mean of reaction time in experimental group was better than the other one (p<0.05), therefore, it can result that the transcranial stimulus of prefrontal cortex method decreased the effect of psychological refractory period. Thus this method can improve the capacity of selective attention or information process in humankind
