Document Summary

Problems perceiving faces op problems attaching meaning to faces. Apperceptive agnosia: failure to recognize objects due to problems perceiving it: not cortical blindness, not a deficit in processing visual information, it is problems with grouping information into mental, test: cannot copy simple line drawing percept. Can"t bind elements of objects (percept) together. Associative agnosia: inability to associate visual forms with to recognize meaning: cant draw objects from memory, cant name objects, cant match functions of objects, test: cannot determine if impossible animals or objects are real or not. Can"t link (associate) a perception with it"s meaning. There is enough information in our environment for us to make sense of the world in a direct way. These patterns are enough so that we don"t have to transform it to perceive or understand it. A passive bottom-up approach to perception: perception is based on the direct stimulation of the sensory organs, this stimulation is used to guide our actions.
