Method: Persian version of the Bergen dichotic listening test was used to evaluate non-forced attention, attention to right and attention to left ears on 75 young adults including 54 right-handed and 21 left handed individuals with normal hearing in age range of 18 to 30 years old. Results: Right ear advantage (REA) with mean score of 78.4% and 94.7% in the two conditions of non-forced attention and attention to the right ear, and left ear advantage (LEA) with mean score of 81.3% in attention to the left ear were obtained. Sex had no effect on the results, but significant difference was found between right and left hand people in non-forced attention and attention to the right (p<0.029). Conclusion:Top-down processing of brain cortex in selective attention modulated bottom-up processing in divided attention task by change of right ear advantage. Our results showed the application of Bergen dichotic listening test to evaluate auditory attention, language laterality and handedness. %> http://icssjournal.ir/article-1-421-en.pdf %P 1-10 %& 1 %! %9 Research %L A-10-2-400 %+ Tehran University of Medical Sciences Faculty of Rehabilitation, Tehran, Iran. %G eng %@ 1561-4174 %[ 2012
