The Geometrical Stroop like task was administered to study the amount of interference in different handed persons in naming geometrical word and their shape when stimuli were presented in two different conditions congruent and incongruent in two visual fields (RVF & LVF). It was hypothesized that, the ability of visual perception can be differing of a person in terms of their handedness. 149 subjects were voluntary participated in this study in which 80 subjects were predominantly Right handed and rest of them were non-right handed, between 17 and 21 years old. Each pair of stimulus was presented for 180msec preceded by a fixation dot for 2000msec. Subjects were asked to respond as fast and as accurately as they could either the geometrical words or the shape or both, depending upon the conditions. Reaction times of correct responses were analyzed. As expected, the results of this study on the basis of Stroop-like experiment give us enough findings in support of hypothesis. The findings of current study indicate that congruency effect in both of the groups. A significantly higher accuracy rates were obtained in non right handed person under the Stroop interference condition. Under this same condition, reaction time analysis yielded also significant differences between two groups.
