The Laboratoire de Perception Visuelle et Sociale has distinguished itself during the NeuroQAM 2020 conference, two students being awarded prizes for the quality of presentations by its members.

Marie-Pier Plouffe-Demers has received a prize for the best “datablitz” type presentation. Here is a summary of her presentation (translated from french):

Impact of Gender on Discrimination of Pain Intensity

Marie-Pier Plouffe-Demers Ph. D. student, Université du Québec à Montréal

SAUMURE, Camille ; FISET, Daniel ; CORMIER, Stéphanie ; KUNZ, Miriam ; BLAIS, Caroline

Studies have shown women have an advantage in discriminating the facial expression of pain, yet few have aimed to understand the underlying differences in visual strategies. This study used the Bubbles method to measure performance and visual strategies of 72 participants (37 men). 2 “bubblized” avatars (2 genders x 4 intensity levels) were presented in each of the 1512 trials. Participants had to determine which of the two expressed the highest level of pain. Precision was maintained constant at 75%, the number of bubbles required to reach this threshold being an indicator of task performance. Results show that men require a higher number of bubbles (M=56, SD=23.16) than women (M=44.5, SD=20.81), suggesting a higher performance for women [t(1,70)=2.22, p<0.029]. Even though both genders use similar regions in the face (i.e. eyes, eyebrows and nose), men use smaller regions than women [t(1,70)=2.43, p=0.017].

Marie-Claude Desjardins has also received a prize for for the best oral presentation. Here is a summary of her presentation (translated from french):

Link Between Visual Representations of the Facial Expression of Pain and Estimating Pain in Others.

Marie-Claude Desjardins Bachelor student, Université du Québec en Outaouais

BLAIS, Caroline ; LÉVESQUE-LACASSE, Alexandra ; CHARBONNEAU, Carine ; FISET, Daniel ; CORMIER, Stéphanie

The underestimation of pain felt by others is a well-documented phenomenon, yet we fail to sufficiently grasp the role visual perception plays in this bias. We verified if sensibility to variations in intensity in others’ pain, and the tendency to underestimate reported pain by others, was linked with variations in visual representations (VRs) of the pain facial expression. 73 participants completed a reverse correlation task to extract their VRs; their sensibility and estimation bias were measured by having them estimate pain levels of individuals seen through videos. Sensibility and estimation bias were shown to be linked to variations in VRs. Higher sensibility is linked to more intense VRs (χ2(1)=23.5, p<0.001) and a higher saliency of the eyebrows region (χ2(5)=47.2, p<0.001). Underestimation of pain is linked to less intense VRs (χ2(1)=11.7, p<0.001) and a higher saliency of the mouth region (χ2(5)=41.7,p<0.001).

The LPVS wishes to congratulate the two students for their prizes and the quality of their presentations. The team also congratulates all students and researchers involved in the projects.

Dre Caroline Blais, co-director of the Laboratoire de Perception Visuelle et Sociale, has recently been awarded the Canada Research Chair in Visual and Social Perception by the Natural Sciences and Engineering Research Council (NSERC), from the Federal Government of Canada. This chair will allow her to research and better understand how social factors such as culture can affect the many steps of visual perception.

Here is a summary of the projects associated to this research chair, also available on the Canada Research Chairs repository:

In the current context of globalization and multiculturalism, it is increasingly important that we understand how our visual and sociocultural environments affect visual perception. Dr. Caroline Blais, Canada Research Chair in in Cognitive and Social Vision, aims to increase this understanding.

Most visual perception studies to date have been conducted on Westerners, with the few cross-cultural ones conducted on only two cultures at a time. But Blais and her research team hope to increase data diversity by studying visual processing and the communication of social signals across different cultural groups.

The entire LPVS team wishes to congratulate Dre Blais for this honor, and wishes her success in her new research work.
