The intrinsic relation between rationality or thought on the one hand and sensory information processing or perception on the other hand is a classical topic in the philosophy of mind. This work contributes to this traditional debate by introducing an interdisciplinary framework, in which the relation between perception and cognition can be explored from a philosophical point of view and, at the same time, on the basis of the latest findings from empirical perception research. Discussing the case of visual object recognition, the proposed model allows us to differentiate between a variety of perceptual phenomena and to clarify our understanding of the role of concepts within perception. As such, it takes a stand in the debate about the conceptuality of perceptual content, exemplifying at which stage of perception and by virtue of which mechanisms perceptual experience becomes enriched or even influenced by prior knowledge or cognition in general. The final chapter is dedicated to the discussion of face perception, its disorders and underlying mechanisms. sakriti opis
