Research Theme

The vision team of the Laboratoire Psychologie de la Perception has research interests in all aspects of visual perception. Its expertise covers visual attention, visual awareness and perceptual decisions, sensorimotor coupling, 3D perception, and the interaction of vision with the other senses. It relies on experimental methods issued from psychophysics, neuroimagery, patient studies, and modelling. Specific research topics include motion perception, colour modelling, visual attention, three-dimensional perception from multiple cues, cross-modal interactions, eye-movements, perception-action interactions, intention-based vs. reflexive actions, and time perception.

Visual confidence refers to an observer’s ability to judge the accuracy of her perceptual decisions. Even though confidence judgments have been recorded since the early days of psychophysics, it is only recently that they have been recognized as essential for a more complete understanding of visual perception (Kiani & Shadlen, 2009, Science; Barthelmé & Mamassian, 2010, PNAS). The purpose of the project will be to test psychophysically in human adults specific predictions of models of confidence judgments that are issued from signal detection theory and accumulation models.
