Change Blindness: a Literature Review on Attention

Koivisto and Revonsuo did an experiment that shows that when someone is focused on one thing they will not see the other thing that is going on in the same direction. Koivisto and Revonsuo wrote, “When participants are attending to a subset of visual targets or events and ignoring irrelevant distractors (‘‘selective looking’’), they often fail to detect the appearance of an unexpected visual object or event even when the object is visible for several seconds (‘‘sustained

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

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.

Perception refers to the process of taking in, organizing, and interpreting sensory data. Perception is multimodal, with multiple sensory inputs contributing to motor responses (Bertenthal 1996). In this paper, I will discuss the many differences between people with autism and the people without and how each person reacts to the same stimuli differently. I will focus on a teenage boy named Brandon, who has Autism, the parents have known that he had ASD since he was 16 months of age where they entered him into early intervention. Each person focuses differently on the perception of each thing in the world, but when you add a person with autism into the mix everything changes completely. When it comes to perception I believe that top-down processing is going to be the focus of this paper since, it has a lot to do with perception, that perception may start with the brain this includes a person’s knowledge, experience, and expectation.

In 007 Bond Girl, there is a scene where Halle Berry is coming out of the ocean. She is clearly drenched as she is exiting the water but a few moments later when she approaches Bond, she appears as if she had never been in the water at all.

In the article review, “Failure to Detect Changes in People During a Real-World Interaction,” Daniel T. Levin of Kent University and Daniel J. Simpson of Harvard university sought to research change blindness, but through a different perspective than previous research. In many previous studies, change blindness was tested through moving images, two-dimensional images on television or computer screens, or even through in-lab tests. Through previous tests on the subject of change blindness, researchers have insinuated that people cannot recognize simple changes in computer stimulated program experimenters due to their retinal capability being hindered by flashing objects on

Researchers do differ on their perspectives on change blindness depending upon their method approach and background or field; however literature is largely in an agreed consensus as to what change blindness is and its effects on attention. Change blindness is studied by using the methodology of change detection, which is where participants are shown two stimuli that are

In Dretske's paper over "what change blindness teaches about consciousness," I think one of the most important ideas pointed out is that what is in question is not what the person thinks they saw or were aware of, but what they actually were aware of. This is really hard to test and get results on accurately.

Change blindness occurs when the observer does not noticed any changes in their visual field.

The first thing I learned is about change blindness. In change blindness we do not notice big changes that occur. This helps me understand that my brain is concentrating at one task at a time. For example, the video shows this by demonstrating that we only focused on the money that the man had, which caused us not to see the change in the background.

Parron and colleagues conducted a study where children with ASD (autism spectrum disorder) were asked to recognise biological motion through the use of PLDs (point light displays). They aimed to find whether high functioning children with autism showed the same specific problem with perceiving emotional material in PLDs in comparison to typically developing children. Secondly, they wanted to explore the degree performance on these tasks and whether it is comparable to high functioning adults with ASD. The use of PLDs depicted different motions depending on the four conditions which included, a person’s actions, subjective states, emotional condition and everyday objects. Participants were asked to describe the PLD as accurately as

The human brain has a limited capacity to deal with the incoming information but yet every moment we encounter a large variety of stimuli like sights, sounds and smells. However, as mentioned above if we encounter stimuli which conflict with our schemas, we reconstruct our memory in order to fit our schemas. The human brain therefore focuses on some aspects of the situation while ignoring the others in order to cope with the sensory barrage. This process of choosing stimuli is called selective attention. Eyewitnesses tend to collect information that relates to their interests and may ignore other vital aspects

Change blindness and inattentional blindness are very closely related because they correspond to an individual’s ability to perceive a change or an obvious and unexpected stimulus that is in plain sight. Change blindness refers to a perceptual phenomenon where

The interesting thing about this book, it reflect our daily behavior on how we making our decisions. It described the four common misleading shortcut on making decision, availability heuristic, representativeness heuristic, confirmation heuristic, affects heuristic. Common heuristic simplify our decision and save our time, however sometimes lead to costly mistakes. Furthermore Bazerman explained how we are automatically driven by system 1, which impact our decision quality. Our continuous bad habits such as, of self-overestimating, self-enhancement, over precision, ignore feedback from others are another examples of decision quality deformation.
