Define Challenge Blindness

The United States has many minority groups that face oppression. In the media today, most of the minority issues that are highlighted involve the LGBTQ community, women, and racial minorities. Differently-abled people are rarely given the space to share with the world how they see it. This literature review will discuss terms related to visual impairment, legislative measures taken in the United States to assist those with severe visual impairments, and the oppression and discrimination those who are visually impaired face.

Obstacles change our way of thought and affect our emotions. A person’s values change as well as their character and they develop an understanding on their situation. Through the hardships of any situation, there is some way or another a solution only in the presence of desire.

The use of certain tests listed above has some limitations, such as in the change blindness test, we can not say with 100% certainty where the participant have seen changes, and where just click on the keyboard buttons. About this restriction also mentioned Levin, Momen, IV & Simons, they also coined the term "change blindness blindness" which characterizes the misconceptions about the vision due to the fact that some participants in the experiment have given the answer at random trying to guess what was supposed to be the right answer. The motivation to divining the answer may be a desire to look smart and impress yourself and others (2010). In some tests, such as

The purpose of the study was to measure the effect that the Flicker Paradigm had on visual perception. The Flicker Paradigm causes a distraction while there is a change made in the image. It was designed to test how long the groups took to react to a change in the visual field. The test is meant to show that the disturbance in the visual field made it much more challenging for the viewer to notice any changes that were made in the image. The hypothesis stated that the experimental group, the group using the Flicker Paradigm, would take longer to notice the change in the visual field than the control group, which had no flicker between the altered images. This is because the disturbance in the visual field caused the brain to miss the change that was made to the image because the information was deemed as unimportant. The majority of the perceived changes occurred in the background of the scene, and were considered minor in reference to the whole scene. This was proven true from the data collected, and coincided with previous tests. (Rensink, R. A. 2000). The data in tables 1.1 and 1.3 shows the individual participant data for the test with a flicker for both tests one and two. Tables 1.2 and 1.4 represent the individual results for the tests with no flicker, or the control group. Graphs 1.1 and 1.2 showed the relationship between the time taken to recognize alterations in the images. The data was taken from the average time to recognize the change from all

According to research, the earliest experimental change blindness is developed from the phenomena such as eye movements and more on working memory. It depends on the personal attention to the images they perceive (MacWhinney, 2001). Although individual have well informed and good memory on whether or not they have perceived an image, they also have poor recalling ability especially on the smaller details that are presented in that image. This is evidently through presentation of the complex pictures that are stimulated

A study conducted by Gusev, Mikhaylova, and Utochkin used the flicker paradigm as described by Rensink et. al (1997) to observe the effect of different stimuli on change blindness. The different stimuli studied were number of objects, object organization, object shape, appearance/disappearance of an object, object shift, color change of an object, and increasing the interstimulus interval (blank screen

Diversity is usually portrayed as the acceptance of many different races and geographical cultures. It is not as common to hear the lack of diversity towards the blind community but it exists. The attendance of Texas State University has opened up the doors to one of the most diverse places I have had the chance to experience first-hand. Although Texas State has become somewhat of a safe-haven, that does not displace the fact that there is stereotyping everywhere against the blind.

The Battle Royale at the beginning of the novel sets the stage for the rest of the novel by combining several of its themes into one scene. The Invisible Man’s blindness to the intention of white men and his role in society is shown through metaphors within the span of the fight. The narrator suffers under the illusion that he is respected as a person, but is still demeaned by white people. Several snippets of the scene help to foreshadow crucial events that change the Invisible Man to an optimistic youth into a vengeful man.

Blindness is a motif that readers see throughout King Lear in many characters such as Lear and Gloucester since they are unable to see the truth. Although blindness in the modern world is defined as not having sight, William Shakespeare tells readers that being able to see does not mean morally and spiritually you can see. Lear’s blindness causes him not to see the treachery behind Goneril and Regan at the beginning of the play which causes him to lose his throne and go mad near the end. Also Gloucester is also blind as he does not see the lies hidden behind the truths that Edmund tells him and later when Cornwall pulls out Gloucester’s eyes, Gloucester is able to see the truths and realizes that Edgar is the legitimate son. Shakespeare shows us throughout King Lear that seeing is more than just through our eyes. The play is centered on true visions and blindness.

The blind leading the blind exercise allowed my partner and I to guide each other from the Barbara Jordan statue to the Martin Luther King Statue, while one of us was blindfolded and the person who was not blindfolded was leading the way. Before my partner and I completed the exercise I did have a few concerns about completing it due to the harm that could be caused during the exercise. The main concern I had was that my partner would not be paying careful attention to where I was going and I would eventually end up hitting someone or falling. Another one of my concerns was my partner would be very impatient with me and not think about the difficulty of walking with a blindfold on, which could also cause

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

Foster introduces the blind man in chapter 22 in his novel. He mentions how physical blindness is important when brought into a story. He says it starts to make the other characters change and “behave differently”. He also says how when a blind person is introduced something important is “at stake” and the author is trying to emphasize the levels of sight beyond the physical one. He sort of shows how the blindness of a character can also be quite ironic. Those who are blind are able to see and those who are able to see are blind. This could be applied to many things such as the blind knowing the certain truth while the sighted are doubtful and don’t really know the truth. Foster also describes blindness as a metaphor for failing. The blind

Persistence of vision is the name given to the phenomenon when images are shown together within a short amount of time and it gives the illusion that the images are moving. The reason that our eyes see the images in this way is due to our brain only being able to process a certain amount of information at a time, when images are shown in progression the human eye sees it as though it's moving. One example of where the persistence of vision has been used is in the films that we watch. This is because there are many frames every second which makes the movie appear incredibly smooth when we see the succession of the images being displayed. Another example of where the persistence of vision has been used is in flip books. Flip books have a slightly

Vision challenge or impairment is when a person’s degree of seeing is very low and the affected person requires assistance in order to carry out daily routine. Significantly, for one to qualify as visually impaired there must be prove that a person cannot undertake duties by himself without necessary assistance. For a person to qualify as a visually challenged, there must be a prove that the affected eyes cannot be conventionally treated. Visual challenge cannot be corrected by surgery, refractive measures neither by medication and that is why it is termed as visual impairment. The most rampart causes of visual challenge are trauma, degenerative or congenital means and a variety of diseases. In the society,
