Perception and Psychology

Isabelle Arsenau-Bruneau (BRAMS)

This study aims to better understand improvements related to training in auditory perception by examining an integrative auditory response called the frequency following response (FFR). FFRs provide a way of measuring individuals' brain representations of sound (speech, music). Musicians are of particular interest because of correlations between their FFR quality and perception skills. The greater the musical training, the closer the neuronal representation approaches the corresponding sound. This is a remarkable phenomenon, but how these enhancements are achieved remains unclear. Using a newly developed procedure that combines electroencephalography [EEG] and machine learning classifiers, our protocol compares the FFR of highly-trained pianists and nonmusicians while they play a short melody and while they hear the same sounds passively.

Quelles sont les spécificités de l’étude de la musique de jeu vidéo ? Dans cette courte présentation, je vous propose de découvrir la ludomusicologie et de comprendre de quelle manière on analyse l’environnement sonore d’un jeu vidéo. Si on a commencé par s’intéresser à la musique uniquement, les paradigmes de jouabilité et d’interactivité ont mis en lumière l’importance de l’environnement sonore complet. Comment, dès lors, analyser à la fois la musique et le son d’un jeu vidéo ? Cette présentation permettra de découvrir plusieurs approches ludomusicologiques.

Cette étude a pour objectif d’explorer l’influence de l’environnement visuel, à savoir son niveau de bruit visuel (issu des distractions visuelles) ou son potentiel restaurateur (de stress), sur la production de la parole. Nous voulions explorer plus précisément l’influence de plusieurs types de salles de classe sur le niveau d’intensité vocale (dB) lors de la production de la parole d’un locuteur.

Perceiving instrument register and playing effort though timbral cues

Erica Huynh and Jade Roth (CIRMMT)

Playing effort is perceived through the physical difficulty of playing in the highest register of an instrument, regardless of its location in pitch space compared to other instrument ranges (e.g., a B4 played on the cello would be perceived as requiring more effort than a C5 on the violin, despite being lower in pitch). Whereas tension is perceived in stringed instruments as proportional to the shortness of the vibrating string, for blown instruments playing effort increases for low tones as well (e.g., flutes, recorder, etc.). We hypothesize unique qualities of timbre related to playing effort will be perceivable by participants, allowing them to locate the register (i.e., low, middle, high) within the pitch range (tessitura) of each instrument.

Directing attention in contemporary composition with timbre

Max Henry, Xiaohan Bao and Jonas Regnier (CIRMMT)

Our goal is to investigate the role of timbre in attention and stream segregation in the context of contemporary classical music. We hypothesize that when focusing on a certain timbre, e.g., a trumpet, one is concurrently more sensitive to trumpet-like sounds, and, more importantly, less sensitive to non-trumpet- like sounds. In music listening, this may lead to an attentional linking between timbrally similar motifs.

Misophonia: Identification of acoustic features in evoking ‘mastication rage’

Iza Korsmit and Savvas Kazazis (CIRMMT)

Misophonia, also known as ‘selective sound sensitivity’, is a psychological disorder that is characterized by negative emotional reactions and autonomic arousal in response to specific environmental sounds. The affective response is mostly characterized by irritation, anger, or panic. Typical triggers are other people chewing, clearing their throat or typing, and the wide prevalence of these sounds in daily life can have large negative effects on the well-being and functioning of people with misophonia. The goal of this project is to shed light on the acoustic features of trigger sounds, to examine whether misophonia is a purely auditory disorder, a social one, or a combination of both.
