Music models aberrant rule decoding and reward valuation in dementia

Published in: Social Cognitive and Affective Neuroscience, Volume 13, Issue 2, 192-202 Abstract “Aberrant rule- and reward-based processes underpin abnormalities of socio-emotional behaviour in major dementias. However, these processes remain poorly characterized. Here we used music to probe rule decoding and reward valuation in patients with frontotemporal dementia (FTD) syndromes and Alzheimer’s disease (AD) relative to healthy age-matched individuals. We created short melodies that were either harmonically resolved (‘finished’) or unresolved (‘unfinished’); the task was to classify each melody as finished or unfinished (rule processing) and rate its subjective pleasantness (reward valuation). Results were adjusted for elementary pitch and executive processing;… Read More

Creating Time: Social Collaboration in Music Improvisation

Published in: Topics in Cognitive Science, Volume 10, Issue 1, 95-119 Abstract “Musical collaboration emerges from the complex interaction of environmental and informational constraints, including those of the instruments and the performance context. Music improvisation in particular is more like everyday interaction in that dynamics emerge spontaneously without a rehearsed score or script. We examined how the structure of the musical context affords and shapes interactions between improvising musicians. Six pairs of professional piano players improvised with two different backing tracks while we recorded both the music produced and the movements of their heads, left arms, and right arms. The backing… Read More

Maintenance of memory for melodies: Articulation or attentional refreshing?

Published in: Psychonomic Bulletin & Review, Volume 24, Issue 6, December 2017, 1964-1970 Abstract “Past research on the effects of articulatory suppression on working memory for nonverbal sounds has been characterized by discrepant findings, which suggests that multiple mechanisms may be involved in the rehearsal of nonverbal sounds. In two experiments we examined the potential roles of two theoretical mechanisms of verbal working memory—articulatory rehearsal and attentional refreshing—in the maintenance of memory for short melodies. In both experiments, participants performed a same–different melody comparison task. During an 8-s retention interval, interference tasks were introduced to suppress articulatory rehearsal, attentional refreshing, or… Read More

Decision mechanisms underlying mood-congruent emotional classification

Published in: Cognition and Emotion, Volume 32, Issue 2, 249-258 Abstract “There is great interest in understanding whether and how mood influences affective processing. Results in the literature have been mixed: some studies show mood-congruent processing but others do not. One limitation of previous work is that decision components for affective processing and responses biases are not dissociated. The present study explored the roles of affective processing and response biases using a drift-diffusion model (DDM) of simple choice. In two experiments, participants decided if words were emotionally positive or negative while listening to music that induced positive or negative mood. The… Read More

Musical competence and phoneme perception in a foreign language

Published in: Psychonomic Bulletin & Review, Volume 24, Issue 6, December 2017, 1929-1934 Abstract “We investigated whether musical competence was associated with the perception of foreign-language phonemes. The sample comprised adult native-speakers of English who varied in music training. The measures included tests of general cognitive abilities, melody and rhythm perception, and the perception of consonantal contrasts that were phonemic in Zulu but not in English. Music training was associated positively with performance on the tests of melody and rhythm perception, but not with performance on the phoneme-perception task. In other words, we found no evidence for transfer of music training… Read More
