A neurophysiological study into the foundations of tonal harmony.
Abstract
Our findings provide magnetoencephalographic evidence that the mismatch-negativity
response to two-note chords (dyads) is modulated by a combination of abstract cognitive
differences and lower-level differences in the auditory signal. Participants were
presented with series of simple-ratio sinusoidal dyads (perfect fourths and perfect
fifths) in which the difference between the standard and deviant dyad exhibited an
interval change, a shift in pitch space, or both. In addition, the standard-deviant
pair of dyads either shared one note or both notes were changed. Only the condition
that featured both abstract changes (interval change and pitch-space shift) and two
novel notes showed a significantly larger magnetoencephalographic mismatch-negativity
response than the other conditions in the right hemisphere. Implications for music
and language processing are discussed.

Dr. Bergelson accepts PhD applicants through the Developmental and Cog/CogNeuro areas
of P&N and the CNAP program.In my research, I try to understand the interplay of processes
during language acquisition. In particular, I am interested in how word learning relates
to other aspects of learning language (e.g. speech sound acquisition, grammar/morphology
learning), and social/cognitive development more broadly (e.g. joint attention processes)
