Musical training engenders structural and functional differences in the auditory cortex. Musicians have demonstrated superior auditory processing abilities compared to non-musicians, particularly when detecting deviants in complex tonal, melodic, and musical regularities. This study investigates whether musicians respond differently to deviants in speech compared to non-musicians by analyzing mismatch negativity (MMN) responses using temporally-cued contrasts stimuli. Speech discrimination abilities are also assessed using the Quick Speech-in-Noise (QuickSIN) test. A total of 17 participants, eight instrumental musicians and nine non-musicians, ranging between 22 and 40 years old were included in this study. A 32-channel research-grade EEG amplifier cap collected brainwave activity and MMN responses to a recorded speech stimulus. Both musician and non-musician participant groups achieved significant MMN responses in various channels during different time frames after speech deviant detection. Results showed that non-musicians had larger, later MMN in frontal, central regions of the brain (where MMN is typically most robust) compared to musicians. The musician group demonstrated earlier MMN to speech deviants in the temporal lobe, where language and auditory processing occurs. QuickSIN testing showed a ceiling effect. Findings from this study suggest that musicians may enter a more language-focused mode instead of auditory/sound-focused mode when presented with speech stimuli compared to non-musicians.
