The LPVS team distinguished itself during the last events organized by the NeuroQAM group last fall.
First, Danielle Samson, Marie-Pier Plouffe-Demers and Camille Saumure have distinguished themselves by winning the 3rd place in the scientific popularization contest that took place last September. Here is the link to watch their presentation:
The impact of the cultural environment on the perception of pain
SAMSON, Danielle ; PLOUFFE-DEMERS, Marie-Pier ; SAUMURE, Camille
Then, Pierre-Louis Audette won a prize for his poster presentation at the November 25 and 26 Science Day. Here is the abstract of his presentation:
The impact of facial contour on the efficiency of perceptual integration

A classic hypothesis in the field of face recognition is that faces represent a “special” class of stimuli. According to this idea, faces would be recognized through holistic processing, i.e., the face as a whole has an advantage in its visual processing when compared to the sum of the processing of all its isolated parts. Gold et al. (2012) proposed an experimental paradigm to measure the advantage of the whole over the sum of its parts. This paradigm requires measuring the level of contrast needed to achieve a pre-specified level of performance (e.g., 75%) and does so for 5 experimental conditions manipulating the information available to participants: left eye, right eye, nose, mouth, four features combined. An integration index is then calculated by dividing the square of the participant’s sensitivity for complete faces by the addition of the square of his sensitivity for isolated features. However, their experimental paradigm does not include the face contour, a feature that could influence the efficiency of perceptual integration. In the present study, we added the natural contour condition as an isolated feature and the full face condition including the natural contour. We tested 6 participants (2520 trials per participant) on these seven conditions to compare the integration index with and without the natural contour. Five of the six participants had a higher integration index with the natural contour included, suggesting the positive impact of this feature on perceptual integration.
The LPVS team would like to congratulate the four students for these distinctions and the quality of their presentations. The LPVS also thanks all the students and researchers involved in these research projects.
