Abstract: Recent investigations have demonstrated significant differences in P300 amplitude between musicians and non-musicians in oddball tasks. We compared Musicians (n = 5) with at minimum 5 years of formal musical training (piano) and one concert performance, to Non-Musicians (n = 5) with no prior musical training on a binaural listening ERP task in which they were required to detect rare high-pitched deviant tones (10%) among low-pitched frequent tones (1000 Hz) occurring randomly in both ears. Difficulty of pitch discrimination was manipulated by using 1128-Hz (EASY) and 1028-Hz (HARD) targets in separate blocks. Results revealed that Musicians had larger P300 amplitudes to tar ets presented to their right ear than Non-Musicians. P300 amplitude was also larger for Musicians than Non-Musicians at a left (C3) but not at a right (C4) hemisphere electrode. Results support both previous P300 findings and findings of hemispheric differences in auditory processing between musicians and non-musicians.
