Essay On Change Blindness

It is said that there are many different versions to a story. There is one persons story, then there is an other person’s story, and then, there is the truth. “Our memories change each time they are recalled. What we recall is only a facsimile of things gone by.” Dobrin, Arthur. "Your Memory Isn't What You Think It Is." (online magazine). Psychology Today. July 16, 2013. http://www.psychologytoday.com/blog/am-i-right/201307/your-memory-isnt-what-you-think-it-is. Every time a story is told, it changes. From Disney movies to books, to what we tell our friends and colleagues. Sometimes the different sides to the story challenge the

The majority of people will decide to change their health behavior throughout their lifetime. The reasons for the change might be quite different from individual to individual. Some may be motivated to take action after experiencing a life threatening illness, while others are proactive and change their health behavior to decrease the risks of developing a potential disease. However, even if the reasons for the change are valid and well understood, there is a great possibility that one will not follow set goals long term. Stacy Carter, an assistant of professor and an author of the Social Validity Manual, expresses her opinion about people implementing a scientifically proven health behavior change treatment in their routine, “if it's something that is going to cause them a lot of effort, or is difficult to implement, then they probably are not going to use it for long” (Cranford, 2011).

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

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 studying different types of scene changes in the hopes of understanding which changes are easier or harder to notice. The results of these studies were quantified by the measurement of change detection time (usually reported in seconds). This subset of change blindness research has far-reaching practical applications, especially in the field of security and law enforcement. By applying the knowledge of which type of stimuli lead to longer change detection times training programs could be developed that allow this population to improve their observation skills.

This time it consisted of actual studied scenes at test time and new scenes that were similar to the studied scene. Also some new scenes all together resembling neither. Experiment 2 used eighteen students from CSU who were paid for their participation. The experimenter uses the same course of action as in test 1, however no test name was given for each scene. Plus, each stage of the test contained 24 scenes 8 were shown at study, 8 new and alike the studied scenes, and 8 new ones all together. The scenes were shown the same amount of times and then they were required to rate the test scene from 0 – 10 for familiarity just like experiment 1. In addition, how well they recognize old vs. new, and if they experienced any déjà vu. The results were that participants were able to recall new test scenes that were similar to studied scenes. They didn’t confuse the new scenes as the old, and 8 were perfect. Two participants claimed that they experienced déjà vu for all of the old scenes, and 15 participants concluded that 77% of old scenes were recognized as being old 24% reported having déjà vu, 23% were wrongly labeled new 58% claimed déjà vu. 91% of the scenes that were alike were identified as new 35% which reported déjà vu, and 95% of the non-similar scenes were identified as new, 19% claimed déjà vu. Old scenes were mistakenly recognized as new drew out a higher rate of déjà vu responses as

ABSTRACT: The aim of this paper is to defend a broad concept of visual perception, according to which it is a sufficient condition for visual perception that subjects receive visual information in a way which enables them to give reliably correct answers about the objects presented to them. According to this view, blindsight, non-epistemic seeing, and conscious visual experience count as proper types of visual perception. This leads to two consequences concerning the role of the phenomenal qualities of visual experiences. First, phenomenal qualities are not necessary in order to see something, because in the case of blindsight, subjects can see objects without experiences phenomenal

Change blindness is when a person has difficulty detecting a change in a scene (Goldstein, 2014). Davies and Hine (2007) found that most people fail to notice when one person in a scene takes the place of another individual despite the fact that the two individuals look vastly different. Similarly, Smart, Berry, and Rodriguez (2014) found that law enforcement officers are also susceptible to change blindness and frequently fail to identify the correct perpetrator in a lineup.

The concept of change blindness has been addressed over the course of nearly half a century, with increasing focus on the subject throughout the past five years (3). Although biologists, psychologists, and philosophers have yet to resolve definitively the paradox of looking without seeing, the investigation of each theory on the matter yields deeper insight into visual perception and sight as well as a decreasingly incorrect understanding of those components of the nervous system, which are crucial for visual cognition. Under normal viewing conditions, changes produce transient signals that can draw attention. Change blindness studies are designed to eliminate or block these transient signals by inserting a visual disruption when the change occurs (3). Flicker Paradigm studies examine the occurrence of change blindness and attempt to explain the inability to not see that which is directly in front of our eyes. The Flicker Paradigm demonstrates the essentiality of attention in the process of seeing (4). The alternation of an object and a modified version of that same object is interrupted by millisecond flashes of blank space. Subjects are then asked to report changes in the images.

One failure of awareness that seems to have a connection with traffic accidents is change blindness. Rensink (2002) proposed that change blindness occurs when a change within the scene goes unnoticed, due to the inability or difficulty to detect it. Resink (2002) also explained that change blindness can take place during a disruption in vision, such as an eye- movement or a blink.

There are two prominent distortions of the episodic memory system: forgetting and the false memory effect. False memory is the propensity to report an event as part of an episodic experience that was not actually present (Holliday, Brainerd, & Reyna, 2011). Several theories give an explanation for this effect, but the most prominent one is the fuzzy trace theory,

Memory does not work like a video camera, smoothly recording every detail. Instead, memory is more of a constructive process. We remember the details that we find most important and relevant. Due to the reconstructive nature of memory, the assimilation of old and new information has the ability to cause vulnerable memories to become distorted. This is also known as the misinformation effect (Loftus, 1997). It is not uncommon for individuals to fill in memory gaps with what they assume they must have experienced. We not only distort memories for events that we have observed, but, we may also have false memories for events that never occurred at all. False memories are “often created by combing actual memories with suggestions received from

Change. It is a concept often discussed as being an inevitable part of human life, something people has experienced numerous of times, and will continue to experience throughout their lives. Change comes in many forms and has a range of effects, which are either negative or positive on those who experience it and respond to it. Change, particularly in relation to the topic ¡°Changing perspective creates awakening¡±, is a view that is repeatedly explored and been written in poem/film by thousands of composers.

Perception is defined as how you look at others and the world around you. Being able to select, organize and intercept information starts the perceptual process. Perception affects the way people communicate with others. An individual’s pattern of thinking can affect their perception of others. Most people communicate best with people of similar cultures.

In looking at the numerous experiences that I have encountered where change has been more than needed and wanted, I feel that my experience working in the Salt Lake Valley Detention Center for five years and leaving to pursue change is a great example of the use of a change model. When I began working in detention in 2009, I felt empowered and validated for the work that I was doing. I also felt that the work that I was doing was making a difference in the lives of the youth I worked with. I had amazing rapport with the youth and staff alike and quickly moved up the latter. As I climbed the latter, I worked to ensure that the staff and I maintained the best interests of the youth. In maintaining a high level of integrity and fairness, we saw dramatic decreases in recidivism among the youth we served and noticed that the staff enjoyed coming to work. However, several years later the facility was sub contracted out and many of the administrative and line positions were cleared out and filled with new personnel. As the new agency filled the positions with various new staff, the change had a negative effect on the previous processes. As the changes continued so did the responses/ behavior of the youth. It seemed like the consideration for the youth and concern for their best interest were pushed aside to fulfill quotas. With the high level of stress this brought on staff, I as well as many others attempted to “Walk on” to find new alternative that would allow us to maintain our efforts, but were unsuccessful. With numerous failed attempts and meetings with admin that resulted in nothing more that frustration, I chose to “Walk out.” In walking out, I continued working with youth in an area that allows me to be a bigger part of the process where I can be more effective. Through this experience, I would say that the seven step process would be very close to the ways in which I addressed the concerns within the detention center prior to leaving and then after as I sought to empower the youth in my community. In part of this change process, I have also undertaken higher education to ensure that I can better meet the needs of those within my community and to strengthen myself so that I can work in situation were those I

When we first unconsciously ‘activate’ a schema, the brain selects what part of aspects of experience we encode. However, when the brain encodes a new experience that may have different properties, but overall may be similar structure; specific details regarding might be getting rid of.
