Sponsor's own description

Since the 19th century, perception has been regarded as an inferential process in which sensory input is compared with prior knowledge, namely the internalised representation of the visual environment. This notion is central to the understanding of everyday perception and cognition in general, and is attracting much attention in various areas of psychology and cognitive neuroscience. However, it is unclear whether and how the primary visual refinement that is thought to underlie the convergence of bottom-up inputs with top-down prior knowledge applies to the processing of meaningful stimuli in our everyday lives. The investigators have shown that human face processing mechanisms are shaped by prior knowledge that the horizontal range of face information conveys the richest and most reliable cues. Furthermore, investigators' previous data suggest that the primary visual cortex is recruited during the progressive refinement of face representation. Using very high field neuroimaging, the present project proposes to follow the neural mechanisms underlying the cortical refinement of horizontal information in human face processing, and to study their contribution to behaviour.
