Individuals with music training in childhood show enhanced pitch processing in music, an effect that generalizes to pitch processing in speech. We examined the effects of a music intervention in infancy on temporal information processing in music and speech. Nine-month-old infants (N = 47) were randomly assigned to controlled music activities  (Intervention) or free play (Control) for 12 sessions in the laboratory. Upon completion, infants’ neural processing of temporal structure in music and speech was quantified by the mismatch response (MMR), measured using magnetoencephalography (MEG). The Intervention group exhibited significantly larger MMRs in response to temporal structure violations in music in both auditory and prefrontal cortical regions. The effects were similar for temporal structure changes in speech. Music intervention in infancy thus enhanced temporal information processing across domains.  Future research is warranted to examine the short-term and long-term behavioral outcome of this intervention as well as to isolate the effects of the various components of the intervention.

Christina Zhao is currently a postdoctoral fellow at the Institute for Learning & Brain Sciences at the University of Washington, where she obtained her Ph.D. in June 2015. Her main research interests concern the effects of auditory experience on neural processing of complex auditory stimuli, particularly music and speech. So far, she has examined the effects of prenatal language experience in newborn speech perception using behavioral measures as well as effects of music experience in 9-month old infants using electrophysiological measures.
