This course aims to introduce students to a scientific study within one of the fundamental cognitive processes concerning visual perception, a broad field of study which will be presented in a cross-disciplinary approach typical of Vision Science. In fact, during the course, some important issues and some of the most recent hypothesis related to how our perceptive system computes information in input will be analysed. These theories are strictly related to crucial parts of some cross-disciplinary fields involving psychophysics, experimental phenomenology, computer vision and, more generally, neuroscience. In order to achieve these objectives the most important research topics related to Vision Science such as perceptual organization, figure-ground segregation, perception of shape, color, space, depth, 3-D, movement and meaning assignment will be studied. All these scientific topics will be investigated taking into account a theoretical perspective aiming to integrate phenomenological data with other data coming from complementary disciplinary contexts including those related to neurobiological and computational studies. In short, during the course it will be shown how vision, considered as a phenomenological system, organizes the real world and, at the same time how the visual system, considered as a mental and neural structure, reacting to electromagnetic radiation, elaborates and codes visual information in a long chain of biological-computational processes.
