The proposed link between brain laterality and individual differences in cognitive tasks provided the theoretical foundation for the present study. The main purpose of this study was to investigate this potential link, specifically between one aspect of brain function, namely hand dominance, and one type of cognitive task, namely the ability to perceive short intervals of time. The sample included 40 girls and 40 boys left hands and 40 girls and 40 boys right hands in school students fasa city  that were selected  with the help of the Edinburgh Handedness Inventory and also time Perception  measured  with  four methods of production, reproduction, verbal estimation and comparison by standard software .Regression analysis showed that age predicted negatively and significantly time perception to the measuring verbal estimation and production method. Handedness was positively and significantly predicted measuring verbal estimation method time perception. Logistic regression results also showed that Handedness predicted the time perception the measuring comparison method. In this study  , not showed significantly different between the sexes. Summarizes the results show that right-handed people than left-handers to perceive higher intervals of time but at the time discrepancies are close to each other have more wrong.
