La plateforme Bubbles : un outil d'investigation des différences individuelles de stratégies de reconnaissance de l'identité des visages
The present study aims to create a web-based platform that would examine individual differences in face processing strategies in different categorization tasks. The purpose of this platform is to collect data from geographically dispersed participants with variable face recognition abilities. Indeed, many studies have shown that there is high variability in the spectrum of face recognition ability, ranging from developmental prosopagnosia (Duchaine & Susilo, 2013), a disorder of face recognition in the absence of brain damage, to super-recognizers, individuals with extraordinary face recognition ability (Russell, Duchaine & Nakayama, 2009). Between these extremes, people vary substantially in their ability to recognize faces. To demonstrate the reliability of creating such a platform for individuals of widely varying abilities, we adapted a recognition task of the identity of famous faces using the Bubbles method (Gosselin & Schyns, 2001) and recruited 12 control subjects and a subject with developmental prosopagnosia. We were able to highlight the importance of the eyes and the mouth in face identification. The best observers seem mostly to use the left side of the face (left eye and the left side of the mouth).
