Visual Agnosia is a disorder that impairs visual recognition due to poor sensory processing. A person with Visual Agnosia is unable to recognize some objects and may have difficulty recognizing, defining, and differentiating between objects. This may be because of the limited number of people who develop Visual Agnosia. There are five different types of Visual Agnosia that impair different mental abilities: Achromatopsia, Prosopagnosia, Prosopamnesia, Apperceptive Agnosia, and Associative Agnosia (“Visual agnosia - Wikipedia, the free encyclopedia,” n.d.). Articles written about Visual Agnosia usually focus on one to very few patients with the disorder.
Research conducted on Visual Agnosia focus on a patient and their particular type of Agnosia, conducting studies to demonstrate how their life is affected by the disorder. In one article the participant was asked to touch, copy, and identify line and silhouetted objects; while she was able to touch and copy the objects she could not name them because of Visual Agnosia (Hiraoka, Suzuki, Hirayama, & Etsuro, n.d., p. 187). The patients reactions is congruent with most Agnosia patients as their ability to identify real objects is stronger than their ability to recognize line drawings/ silhouettes. In another study a participant acted differently she was able to identify objects but could not properly copy the image, even recognizing that it “was not quite right,” (Celesia). For this project we want to present a balance of writing about the many different aspects of Visual Agnosia not just one single part.
Since there is an article on Visual Agnosia currently on Wikipedia our group will be adding to the article as well as editing the current content. Using the research we culminated we will expand on the symptoms, the subtypes, and the types of Visual Agnosia without discussing Visual Agnosia in popular culture. We will use several peer reviewed articles on case studies, and unique cases of Visual Agnosia to expand on the various types of Agnosia, the causes, treatment, effect, and symptoms. We will also use articles discussing the neuropsychological and neuroradiological correlates or Visual Agnosia. The article provides a good definition of Visual Agnosia, but as a group we would like to expand on this complex neurological impairment and really explore all aspects of it.
