Visual Information Processing Paper

Visual agnosia refers to the “…inability to recognize objects that results neither from general intellectual loss nor from a loss of basic sensory abilities,” (Anderson, 2009, p. 32). There are generally two types of visual agnosia: apperceptive agnosia and associative agnosia. Apperceptive agnosia is the inability to recognize or draw simple shapes as they are shown or represented. Associative agnosia is the ability to recognize and copy drawings of simple and complex shapes. However, person with associative agnosia are unable to recognize the complex objects (Anderson, 2009).

Gibson’s and Gregory’s theories of perception both suggest that eye-retina is important for perception. The both believe that without eye-retina, a person will not be able to see. This is a common view of both of the theories of perception. The idea is supported by the case of SB. SB was a man who had been blind from birth due to cataracts. When he was 52, he had an operation which restored his sight and hence he could see. Thus, this case has shown the importance of eye-retina for things to be perceived. And therefore, supports both of theories of perception which eye-retina is essential for perception.

I chose to analyze the case study, Tug Of War that was written by Yossi Sheffi and is found in the Harvard Business Review.

This double dissociation therefore suggests that recognition of faces and common objects is served by different mechanisms that are independent for each other. Although brain cells of face recognition have not been located, some functional models could help us interpret face recognition and prosopagnosia. One of the most influential models was proposed by Bruce and Young (1986). In this model face recognition involves several steps, and three steps more relate to prosopagnosia.

When it comes to neurocognitive disorders and neurodevelopmental disorders, reaserchers have been able to diagnose symptoms of a variety of disorders pertaining to the brain and growth development. Once knowing what the symptoms are behaviors become noticed and there becomes a reason for certain behaviors in individuals allowing different treatments for these disorders..

Our study of the distinctively visual deepens our understanding of the world and those who inhabit it.

In Oliver Sacks’ The Man Who Mistook His Wife for a Hat, he denotes a “deficit is an impairment or incapacity of neurological function; such as loss of speech, loss of language, loss of memory, loss of vision loss of dexterity, or loss of identity” (Sacks, 1985). The specific neurological disorder that is highlighted in chapter one is Visual Agnosia, which is a deficit associated with poor primary visual processing that affects shape perception, figures, object, face and letter recognition (Serino, et al., 2014). Other subtypes of visual agnosia that also seemed to fit the descriptions that Sacks shared is prosopagnosia, which is the inability to recognize human faces (Shah, 2016), and pantomime agnosia, characterized as the inability to understand gestures (Gonzalez, Mack, & Heilman, K., 1986).

This is an anti-smoking advertisement geared towards parents of young children. The advertisement is overall plain and simple; it gets straight to the point when you look at it and utilizes a dark theme. This anti-smoking advertisement is trying to evoke a sense of “parental guilt” into parents who smoke. The way the advertisement is able to do this is through the use of an optical illusion, use of text and the use of negative space.

Humans have a unique and wonderful device in how one sees. The eye and brain work together to turn the world into visual data one’s brain can understand and use. There are some eye conditions that inhibit the sight or the recognition of the shapes one sees. Research continues to overcome these conditions as well as to further understand the biochemical reaction that gives humans the sight and understanding one has of visual data. Included in the paper are some of the latest research methods.

(11) Individuals use the perception process to select, organize, interpret, and retrieve information from the world around them.

Vision is the most important sensory compared to other sensory modality therefore there is a wide range of research carried out on vision. Visual attention is defined as a term that portrays how individuals are able to change their view while attending to an image that is of a normal perspective due to the neurones in the cortex (Carasco, 2011). It is often described as a focal point which is situated with different locations in the region of space (Wright, 1998). Visual search requires detecting a specific target as quickly as possible. For example, trying to find your car in a large car park. By focusing our attention to the specific environment it improves our visual search of the target (Keane et al., 2015). The speed of a visual search

Agnosia is defined as the inability to recognize objects through the processing of sensory information, which means there is no deficit in semantic memory or problems with naming objects. An individual suffering from agnosia still possesses all the relevant semantic information tied to a precept, but they cannot recognize the precept when it is presented to them and therefore trigger the recall of said information. There are many types of agnosia, but this essay will focus on visual object agnosia and prosopagnosia. The former is the inability to recognise objects: patients suffering from visual object agnosia do not have impaired vision, and in some cases can even copy the object they are seeing (patient H.J.A., Humphreys & Riddoch, 1987) or draw it from memory (patient D.F., Milner & Goodale, 1992), but are unable to recognize it when they see it. In the latter, prosopagnosia, patients cannot recognise faces of familiar individuals, and have to rely on other characteristics such as their voice or clothing to recognize them. Patients suffering from prosopagnosia can either acquire it through a lesion in relevant brain areas (acquired prosopagnosia) or for less understood reasons have it from birth, in which case it is termed developmental prosopagnosia. The study of patients with agnosia is integral to the field of visual recognition, as the specifics of their deficits can provide great insight into the ways our brain processes information; for example, the location of

Additional impairments have been noted. These include: anxiety, depression, short-term memory problems, and attention problems (Appleford School, 2008; Vasconcelos, 2009). As such, a variety of comorbid disorders have also been identified, such as ADHD, dyslexia, and Asperger’s syndrome. Due to the high prevalence of co-occurrence, some psychologists question

The foremost human characteristic is the ability to comprehend or perceive. Perception is a vital feature since it is the process by which an individual interprets his immediate environment as well as situations, changes, and interactions within it. Aukrust (2011) states that perception involves the physical sense such as smell, sight, hearing, touch taste, and cognitive processes which are
