Change Blindness a Literature Review on Attention

Change Blindness: A Literature Review on Attention When going about our daily lives, just how much are we missing of the things around us? Visual attention has fascinated psychologists and now research is being carried out to distinguish to what extent, our attention or the absence of it, can affect our day-to-day lives. Change blindness is something we all experience at some point, some more than others. By definition it refers to the failure a person has to notice a change that would otherwise seem obvious when pointed out. (Watson, Leekam, Connolly, Collis, Findlay, McConachie amp; Rodgers, 2012). Researchers believe there are a few different causes for this such as altered position, eye movements, a visual obstruction or in the†¦show more content†¦Change detection has also been used to investigate the ways in which people with atypical development such as autism have any particular attentional preferences. (Watson et al. 2012). Usually the images shown to the viewer are a real life scene or location where a change occu rs. These changes are made so that they are neither too subtle nor too obvious to the participant. Changes in the images presented can include colour, location or the presence or absence of a particular object. (Watson et al. 2012). It is predicted that the participants would be able to pick up on the change that is taking place as visual transients generally capture attention. (Cavanaugh amp; Wurtz, 2004). It is largely thought that when viewing a display, focussed attention on a specific object is required in order to detect a change. (Rensink et al. 1997). O’Regan, Deubel, Clark amp; Rensink highlight that internal representation of the visual field only contains the particular aspects that have been attended to in a scene. (2000). We can relate this back to the example used previously by Caplovitz, Fendrich amp; Hughes where we can only be reassured that our keys are not in one place by focussing our attention on that spot. Until then we are unsure of where exactly our keys might be and cannot rule out the possibility that we left them on the sofa. This is due to the fact that when visually processing a particular scene, weShow MoreRelatedChange Blindness: a Literature Review on Attention1674 Words   |  7 PagesChange Blindness: A Literature Review on Attention When going about our daily lives, just how much are we missing of the things around us?

Literature on change blindness is quite extensive, as it is an emerging area in psychology. A number of researchers have conducted experiments into the key areas where change blindness has been found to cause consequential outcomes. These areas include the effects of change blindness on eye witness testimonies, driving ability, and effects on autism. Literature on change blindness places an emphasisRead MoreChange Blindness And The Field Of Human Sensation And Perception1926 Words   |  8 Pages Change blindness is a phenomenon in attention where drastic changes to a scene can go unnoticed. This is important to the field of Human Sensation and Perception because it helps illustrate how a visual scene is processed. Specifically it shows how even if there is direct attention to a scene, there are times when drastic changes can occur without perception of the change occurring. With extensive research already conducted illustrating this effect, new research has recently been conducted studyingRead MoreSymptoms And Treatment Of Diabetic Screening Tests1312 Words   |  6 PagesIntroduction In 2012, 29.1 million Americans, or 9.3% of the United States population, had diabetes. Nearly 28% of those with diabetes were undiagnosed (â€Å"Statistics about diabetes†, 2014). Diabetes remains one of the leading causes of death, but minimal attention has been given to the screening opportunities that exist in acute-care settings for undiagnosed patients. This has been largely due to the misconception that hyperglycemia in the acute setting is a common occurrence related to stress and does notRead MoreAnalysis Of There s More Than Meets The Eye 2389 Words   |  10 Pagesdeemed as invalids or sullen characters that live unfulfilling lives. However, to the contrary, the blind are able to live fulfilling lives that contribute happiness to themselves and to others. Even though it may seem as a lifelong disability, blindness should not be an excuse to avoid living life to the fullest. Achieving personal goals, reaching important milestones, and living as positively as possib le, are the most important factors and values that the blind abide by.

Disability can be classified into two types:- Physical impairment and Mental impairments’. Physical impairments include anything from loss of a limb, sensory impairment(paralysis), blindness, deafness and generally everything that alters physical appearance and performance of an individual.

Studies reveal that Americans attend to predominantly central focal objects (Ji, Peng and Nisbett, 2000; Nisbett and Masuda, 2003); that is to say, visual information is processed in a field-independent way, paying less attention to an objects environment.

Though the â€Å"spot the difference† task is a great study to look at in relation to visual perception, very little research has been done on the task and its relation to vision.

Findings suggest that college students with ADHD/ADD experience academic and psychological difficulties that put them at a greater risk for earning low grade point averages, being on academic probation, and not graduating from college. These research findings serve as a rationale for implementing a structured skills development’
