To 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.
The 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.
In 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.
These 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.
Researchers should be cautious about using an audible movie soundtrack when measuring auditory ERPs in younger listeners.
确定在儿童、青少年或成年人中，有声音电影配乐是否会对听觉 P1、N1、P2、N2 或失匹配负波（MMN）事件相关电位（ERP）产生负面影响。
在两种条件下（有声音和无声），对 36 名儿童、32 名青少年、19 名大龄青少年和 10 名成年人的听觉 ERP 进行了测量。
在儿童和青少年中，有声音电影配乐对 N1、P2、N2 和 MMN ERP 的振幅、潜伏期或半分可靠性有显著影响。有声音配乐对成年人的听觉 ERP 影响较小。
这些发现对先前声称有声音配乐不会降低儿童听觉 ERP 的说法提出了挑战。此外，在无声和有声两种条件下，MMN 的可靠性均低于 P1、N1、P2 和 N2 波峰。
当在年轻听众中测量听觉 ERP 时，研究人员应谨慎使用有声音电影配乐。
