Abstract

Introduction: The aim of this study was to investigate effect of exercise on visual-auditory and auditory-visual dual frequency assignment in psychological refectory period. Method: 45 students from 18 to 28 years were chosen through purposive sampling from Khorramshahr and were randomly divided into three groups: practicing with task visual-auditory, task auditory-visual and control group, each group consisted of 15 people. The dual task test visual-audio and audio-visual was done with all subjects. The interval between the two stimuli was 50 and 75 (short distance) 200 and 250 ms (long distance) (Generally 8 trial visual-audio and 8 trial audio-visual). The training program included 5 sessions in 5 days. Each session includes 12 blocks of 8 trials with visual-auditory double task personification pre-test and the two-minute rest intervals between blocks. Findings The results of ANOVA showed that there was a significant difference between the groups in terms of all sequences in all four stimulus onsets but there was no significant difference between the display of the visual stimulus presentation and auditory presentations. Conclusion: Double Task Practice by increasing the stimulus-response compatibility reduces the need for attention and reducing the required attention capacity which is possible for the two stimuli at the same processing can have positive effect on psychological refectory period as well as the task of visual-auditory and auditory- visual with an interval of high and low.
