Abstract

ObjectiveTo determine if an audible movie soundtrack has a degrading effect on the auditory P1, N1, P2, N2, or mismatch negativity (MMN) event-related potentials (ERPs) in children, adolescents, or adults.MethodsThe auditory ERPs of 36 children, 32 young adolescents, 19 older adolescents, and 10 adults were measured while they watched a movie in two conditions: with an audible soundtrack and with a silent soundtrack.ResultsIn children and adolescents, the audible movie soundtrack had a significant impact on amplitude, latency or split-half reliability of the N1, P2, N2, and MMN ERPs. The audible soundtrack had minimal impact on the auditory ERPs of adults.ConclusionsThese findings challenge previous claims that an audible soundtrack does not degrade the auditory ERPs of children. Further, the reliability of the MMN is poorer than P1, N1, P2, and N2 peaks in both sound-off and sound-on conditions.SignificanceResearchers should be cautious about using an audible movie soundtrack when measuring auditory ERPs in younger listeners.

► Researchers should be cautious of using an audible movie soundtrack to distract children and adolescents attention while running an auditory ERP experiment. The audible movie soundtrack has a more degrading effect on the passive auditory ERPs of children and adolescents and less in adults. ► The P1 and N1 peak amplitude measures are least affected by an audible movie soundtrack in children and adolescents. ► The reliability of the MMN is lower than the P1, N1, P2, and N2 ERP peaks regardless of whether a movie soundtrack is audible or not.
