Pitch-change sequence processing drives larger N1m and P2m responses than constant notes

Evidence

The response to the first note of the tonic sequence is very similar to the first note of the melodic sequence. Thereafter, however, the adapted responses to notes 2-4 in the melodic sequence (blue) are substantially larger than their counterparts in the tonic sequence (red), both with regard to the N1m component and the P2m component (N100m: t max_note2 = ‑204, p = 0. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4703

The level, duration and timbre of the notes in the tonic and melodic sequences are the same, so the differences in the source waves reflect the processing of the sequence of pitch changes that together constitute the melody. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4703

Categorization

• QUESTION: Worth chasing: can the pitch-processing N1m/P2m enhancement be dissociated from simple note ‘novelty’ or expectation effects in future designs?
• corroborated: 3 independent passages support this claim — Dijk, Pim van, Physiology, Psychoacoustics and…, 4703
• XREF: connects to: Melodic notes produce earlier N1m peaks than tonic notes do.; Melody change processing localizes more anteriorly than energy onset in auditory cortex — Dijk, Pim van, Physiology, Psychoacoustics and…, 4703; Melodic notes evoke larger N1m and P2m responses than tonic notes — Dijk, Pim van, Physiology, Psychoacoustics and…, 4703 (+1 more)
