The Cultural Evolution of Music

15h-16h – Dr. Sam Mehr (Harvard University, MA, USA)
A natural history of song

Theories of the origins of music claim that the music faculty is shaped by the functional design of the human mind. On these ideas, musical behavior and musical structure are expected to exhibit species-wide regularities: music should be characterized by human universals. Many cognitive and evolutionary scientists intuitively accept this idea but no one has any good evidence for it. Most scholars of music, in contrast, intuitively accept the opposite position, citing the staggering diversity of the world’s music as evidence that music is shaped mostly by culture. I will present two papers that attempt to resolve this debate. The first, a pair of experiments, shows that the musical forms of songs in 86 cultures are shaped by their social functions (Mehr & Singh et al., 2018, Current Biology). The second, a descriptive project, applies tools of computational social science to the recently-created Natural History of Song corpora (http://naturalhistoryofsong.org) to demonstrate universals and dimensions of variation in musical behaviors and musical forms (Mehr et al., working paper, https://psyarxiv.com/emq8r).

Samuel Mehr is a Research Associate in the Department of Psychology at Harvard University, where he directs the Music Lab. Originally a musician, Sam earned a B.M. in Music Education from the Eastman School of Music before diving into science at Harvard, where he earned an Ed.D. in Human Development and Education under the mentorship of Elizabeth Spelke, Howard Gardner, and Steven Pinker. 


16h-17h – Dr Nicolas Baumard (Ecole Normale Supérieure, Paris)
Psychological Origins of Cultural Revolutions

Social trust is linked to a host of positive societal outcomes, including improved economic performance, lower crime rates and more inclusive institutions. Yet, the origins of trust remain elusive, partly because social trust is difficult to document in time. Building on recent advances in social cognition, we designed an algorithm to automatically generate trustworthiness evaluations for the facial action units (smile, eye brows, etc.) of portraits in large historical databases. Our results show that trustworthiness in portraits increased over the period 1500 – 2000 paralleling the decline of interpersonal violence and the rise of democratic values observed in Western Europe. Further analyses suggest that this rise of trustworthiness displays is associated with increased living standards.

Nicolas Baumard is a CNRS researcher in the Department of Cognitive Sciences at the École Normale Supérieure in Paris, working in the Evolution and Social Cognition team, at Institut Jean-Nicod. His work uses evolutionary and psychological approaches in the social sciences, in particular in economics and history. More specifically, his recent work has used reciprocity theory (in particular partner choice) to explain why moral judgments and cooperative behaviors are based on considerations of fairness; and Life-history theory to explain behavioral variability across culture, history, social classes and developmental stages.


17h-18h – Pascal Dusapin – The Lullaby Experience Project

Update (18/4): The participation of Pascal Dusapin has been cancelled due to unforeseen circumstances.

Lullaby Experience est un projet participatif imaginé par le compositeur Pascal Dusapin, ouvert à tous, enfants et adultes, partout dans le monde. Chacun de nous possède, inscrit au plus profond de lui-même, une mélodie qui a marqué son enfance. Souvent, cette comptine a été déformée par le temps et la mémoire. C’est ce souvenir que l’on vous demande de chanter, de chuchoter. Les enregistrements collectés fourniront la matière sonore utilisée par le compositeur pour la création musicale Lullaby Experience. Transformés et assemblés, ils dessineront le portrait sonore de chaque ville où l’œuvre sera présentée. La création française de Lullaby Experience aura lieu au CENTQUATRE à Paris en Juin 2019.

Pascal Dusapin fait ses études d’arts plastiques et de sciences, arts et esthétique à l’Université de Paris-Sorbonne. Entre 1974 et 1978 il suit les séminaires de Iannis Xenakis. De 1981 à 1983 il est boursier de la Villa Médicis à Rome. Il reçoit de très nombreuses distinctions dès le début de sa carrière de compositeur. Parmi celles-ci, le Prix symphonique de la Sacem en 1994, le Grand prix national de musique du ministère de la Culture en 1995 et le Grand prix de la ville de Paris en 1998. La Victoire de la musique 1998 lui est attribuée pour le disque gravé avec l’Orchestre national de Lyon, puis de nouveau en 2002, comme « compositeur de l’année ». En 2005, il obtient le prix Cino del Duca remis par l’Académie des Beaux-arts. Il est Commandeur des Arts et des Lettres. Il est élu à la Bayerische Akademie der Schönen Künste en juillet 2006. En 2006 il est nommé professeur au Collège de France à la chaire de création artistique. En 2007, il est lauréat du Prix international Dan David, un prix international d’excellence récompensant les travaux scientifiques et artistiques et qu’il partage avec Zubin Metha pour la musique contemporaine. En 2014, il est Chevalier de l’Ordre national de la Légion d’honneur.

Additional lecture by Sam Mehr: The Origins and functions of music in infancy

In 1871, Darwin wrote, “As neither the enjoyment nor the capacity of producing musical notes are faculties of the least use to man in reference to his daily habits of life, they must be ranked among the most mysterious with which he is endowed.” Infants and parents engage their mysterious musical faculties eagerly, frequently, across most societies, and for most of history. Why should this be? In this talk I propose that infant-directed song functions as an honest signal of parental investment. I support the proposal with two lines of work. First, I show that the perception and production of infant-directed song are characterized by human universals, in cross-cultural studies of music perception run with listeners on the internet; in isolated, small-scale societies; and in infants, who have much less experience than adults with music. Second, I show that the genomic imprinting disorders Prader-Willi and Angelman syndromes, which cause an altered psychology of parental investment, are associated with an altered psychology of music. These findings converge on a psychological function of music in infancy that may underlie more general features
of the human music faculty.

Symposium: the evolution of vocal and facial expressions

At the occasion of the PhD defense of Pablo Arias on Dec. 18th, the CREAM lab is happy to organize a mini-symposium on recent results on the evolution and universality of vocal and facial expressions with two prominent researchers from the field, Dr. Rachael Jack (School of Psychology, University of Glasgow) and Prof. Tecumseh Fitch (Department of Cognitive Biology, University of Vienna). The two talks will be followed in the afternoon by the PhD viva of Pablo Arias on “auditory smiles”, which is also public.

Date: Tuesday December 18th

Hours: 10h30-12h (symposium), 14h (PhD. viva)

Place: Salle Stravinsky, Institut de Recherche et Coordination en Acoustique/Musique (IRCAM), 1 Place Stravinsky 75004 Paris. [access]

Symposium: The evolution of facial and vocal expressions (Dr. Rachael Jack, Prof. Tecumseh Fitch)


10h30-11H15 – Dr. Rachael Jack (University of Glasgow, UK)

Modelling Dynamic Facial Expressions Across Cultures

Facial expressions are one of the most powerful tools for human social communication. However, understanding facial expression communication is challenging due to their sheer number and complexity. Here, I present a program of work designed to address this challenge using a combination of social and cultural psychology, vision science, data-driven psychophysical methods, mathematical psychology, and 3D dynamic computer graphics. Across several studies, I will present work that precisely characterizes how facial expressions of emotion are signaled and decoded within and across cultures, and shows that cross-cultural emotion communication comprises four, not six, main categories. I will also highlight how this work has the potential to inform the design of socially and culturally intelligent robots.



11h15-12h – Prof. Tecumseh Fitch (University of Vienna, Austria)

PhD Defense: Auditory smiles (Pablo Arias)

At 14h on the same day, Pablo Arias (PhD candidate, Sorbonne-Université) will defend his PhD thesis, conducted in the CREAM Lab/ Perception and Sound Design Team (STMS – IRCAM/CNRS/Sorbonne Université). The viva is public, and all are welcome.

14h-16h30 – M. Pablo Arias (IRCAM, CNRS, Sorbonne Université)

The cognition of auditory smiles: a computational approach

Emotions are the fuel of human survival and social development. Not only do we undergo primitive reflexes mediated by ancient brain structures, but we also consciously and unconsciously regulate our emotions in social contexts, affiliating with friends and distancing from foes. One of our main tools for emotion regulation is facial expression and, in particular, smiles. Smiles are deeply grounded in human behavior: they develop early, and are used across cultures to communicate affective states. The mechanisms that underlie their cognitive processing include interactions not only with visual, but also emotional and motor systems. Smiles, trigger facial imitation in their observers, reactions thought to be a key component of the human capacity for empathy. Smiles, however, are not only experienced visually, but also have audible consequences. Although visual smiles have been widely studied, almost nothing is known about the cognitive processing of their auditory counterpart. 

This is the aim of this dissertation. In this work, we characterise and model the smile acoustic fingerprint, and use it to probe how auditory smiles are processed cognitively. We give here evidence that (1) auditory smiles can trigger unconscious facial imitation, that (2) they are cognitively integrated with their visual counterparts during perception, and that (3) the development of these processes does not depend on pre-learned visual associations. We conclude that the embodied mechanisms associated to the visual processing of facial expressions of emotions are in fact equally found in the auditory modality, and that their cognitive development is at least partially independent from visual experience.

Bullying the doc: stronger-sounding patients get more 911 attention

Our team published a new paper this week, in which we test the influence of patients’ tone of voice on medical decisions.

In the line of our recent real-time emotional voice transformations, we manipulated the voice of (fake) patients calling a 911 phone simulator used for training (real) medical doctors, to make them sound more, or less, physically dominant (with deeper, more masculine voices corresponding to lower pitch and greater formant dispersion, see e.g. Sell, A. et al. Adaptations in humans for assessing physical strength from the voice. Proceedings of the Royal Society of London B: Biological Sciences, 277(1699), 3509–3518 (2010) – link).

We found that patients whose voice signalled physical strength obtained a higher grade of response, a higher evaluation of medical emergency and longer attention from medical doctors than callers with strictly identical medical needs whose voice signaled lower physical dominance.

The paper, a collaboration with Laurent Boidron M.D. and his colleagues at the Department of Emergency Medicine of the Dijon CHU Hospital/Université de Bourgogne, was published last tuesday in Scientific Reports (link, pdf).
