Document Summary
Apperceptive: inability to perceive and therefor recognize objects (vision is fine but you can"t put all the information together to create perception. Associative agnosia: can"t recognize (associate) a picture"s meaning (patient won"t be able to tell whether a drawing is realistic or not) and therefore can"t name, draw or tell you an object"s function. Passive bottom up approach: pattern information in our environment leads to perception of everything. Affordances: cues in our environment lead us to see uses/functions of objects shows the link between perception and action. E. g. texture gradients: size and density of texture gradient informs us of a surface"s orientation (bigger and more spread out looks closer than small dense) Topological breakages: surface is cut off by another surface; you perceive them as meeting at a certain point. Scatter reflection: pattern of light scattering shows info about surface (rough surface scatters light more widely)
