Cognitive Psychology- Visual agnosia

[drnaga]

visual agnosia: an inability to recognize visual objects that is neither a function of general intellectual loss nor a loss of basic sensory abilities

Apperceptive agnosia (Benson & Greenberg, 1969)

• soldier who suffered brain damage from carbon monoxide poisoning
• recognized objects through feel, smell, or sound
• could not distinguish between a circle and a square
• could not recognize faces or letters
• could not copy shapes shown to them
• could discriminate colors and which direction an object was moving
• was able to register visual information, but could not combine that information into a perceptual experience

Associative agnosia (Ratcliff & Newcombe, 1982)

able to recognize simple shapes and can copy shapes shown to them
unable to recognize such objects
anchor --> umbrella
apperceptive agnosia --> early perceptual processes are disrupted
associative agnosia --> later processes (pattern recog) are disrupted.

Visual perception can be divided into an early phase in which shapes and objects are extracted from the visual scene and into a later phase in which the shapes and objects are recognized (Anderson, 1995)

Hey friend, thanks for sharing such a nice article, i am really thankful to you. Well, cognitive psychology is the medical research of brain and psychological function, such as learning, memory, interest, belief, thinking. I am also uploading a document where you can find more detailed information.
