Visual agnosia

Agnosia describes a wide variety of phenomena associated with an inability to recognize objects, persons, sounds, shapes, or smells when presented with that stimulus. That failure also occurs in the presence of a usually fully-functional sensory system and without any significant memory loss that could explain the recognition deficiency. Often, the disorder is caused by injury to the brain or some sort of neurological illness that damages certain pathways of the brain. This damage can be induced by strokes, head trauma, encephalitis, or conditions that involve anoxic situations. In terms of location, damage primarily occurs to the parietal, temporal, or occipital lobes of the brain, but it tends to be limited to very specific regions of the…

What have studies of visual object agnosia and prosopagnosia contributed to our understanding of visual recognition? A lot of what we understand about visual recognition comes from investigating cases where the processes involved go wrong. The absence of a cognitive ability can provide is with the ability to look at where things differ in these individuals from those with normal levels of processing. In the case of visual recognition, we can look at different forms of visual agnosias in order…

The purpose of this study was to support the dominant view that the visual system is functionally and anatomically dichotomized according to dissociations between the ventral- and dorsal-streams. To illustrate this hypothesis, James, Culham, Humphrey, Milner, & Goodale (2003) examined the case study of patient D.F., who “suffered severe bilateral damage to her occipitotemporal visual system […], while retaining the use of her occipitoparietal visual system” (James, Culham, Humphrey, Milner, &…

Visual Agnosia The textbook defined visual Agnosia as an impairment in object recognition which can be caused by brain damage. Visual Agnosia is a brain disease that has no cure. In the video, Kevin talked about his issue of visual Agnosia. Kevin can identify colors, faces such as his children’s pictures but can’t be able to locate an object. Kevin plays guitar, he cannot read music but know how to construct music by listening to it and reconnect it with his guitar. Kevin’s visual Agnosia made…

The article illustrates findings describing separate visual pathways within the cortex that play different roles in interpreting visual information. These visual pathways include the ventral and dorsal streams which elicit visual perception and visual control of action, respectively. An important model for these findings was patient D.F., an individual afflicted with visual form agnosia, resulting in difficulties perceiving visual objects. In determining the origin of this patient's condition,…

The first area of the brain to receive input from ganglion cells is the lateral geniculate nucleus of the thalamus. From there the thalamus sends information to the primary visual cortex in the occipital lobe and area V1 sends information back to the thalamus. These two areas feed information back and forth. Area V1 also sends information to the secondary visual cortex (V1) which then relays that information to different areas of the brain. The ventral stream runs along the occipital cortex to…

Walter Bendix Schonflies Benjamin was born into a wealthy Jewish family in Germany. He was a German philosopher who is associated with the Frankfurt School and his areas of interests were literary theory, language, aesthetics, and technology. Benjamin was influences by and is associated with the work of Karl Marx, Theodor Adorno, and Bertolt Brecht. Moreover, one of Benjamin’s most influential writing is titled, The Work of Art in the Age of Mechanical Reproduction (1936). The primary argument…

Aesthetics have come to have a different meaning to me since I first enrolled in the class. I have come to think of the advancements we have made on the topic mind-blowing. I think every philosophy we have looked at has held a truth. Schiller says it is nature that equipped man with the ability to move from what is real to what is not. Nature provided man with two senses to help them create; sight and hearing. Once someone can enjoy sight he is aesthetically free. The power of sight gives…

Constitution’s first amendment, however, free speech is not absolute, and the Supreme Court has the right to ban explicit works of art. This can be seen as a real problem, since art is very subjective, and everyone interprets it differently. So, the real question is, where is the fine line between art and offensiveness? Currently, according to the Supreme Court, art is seen as offensive “if an average person applying contemporary community standards would find that it appeals primarily to…

Introduction This personal action plan will include things such as my personal growth, (how this class as affected my diversity awareness), diversity benefits (things that will benefit me from valuing diversity), diversity communication (how communication will promote diversity awareness), and diversity goals (what my most important diversity goals are for the future. Personal Growth The reason I took this course is because it seemed interesting and I wanted to know more about how others…
