Measuring the Role of Right and Left Hemispheres in Processing Arabic by the Methods of Visual field and Dual-Task Performance

Abstract

The present study investigated the efficiency of the visual
field and the dual- task performance methods in studying Arabic
language processing among 40 Arabic native speakers at Yarmouk
University. Results of both experiments confirmed those of previous
studies that showed the importance of left hemisphere in processing
language. In the first experiment, subjects showed more advantage of
the right visual field (left hemisphere) than the left visual field (right
hemisphere). In the second experiment, subjects also showed more
interference between the tapping task and the linguistic task using
their right hand (left hemisphere) than using their left hand (right
hemisphere). No significant effects were found for sex in the visual
field method, nor in the dual-task performance one
