To examine whether ear dominance in a dichotic pitch-discrimination task is associated with asymmetrical activation of the two cortical hemispheres, ear dominance scores and electroencephalographic (EEG) laterality were correlated in two independent samples (ns=46 and 128). The results indicate that ear dominance can partly be attributed to a relatively stronger activation of the contralateral prefrontal cortex. The observed association may reflect the tendency to direct attention preferably to one ear.
