What Is The Phenomenon Of Change Blindness

In the novel The Invisible Gorilla: How our Intuitions Deceive Us by Christopher Chabris and Daniel Simons, a deeper way of how the mind works is shown. The authors explain what they call the “illusion of attention” by providing experiments and illustrations. The message being passed is that we as humans might think we are always aware of our surroundings, but we actually miss what is right in front of us. People usually focus on one thing at a time, therefore the unexpected goes unnoticed. The book explains how the brain only focuses on the object or area you are concentrating on, making you “blind” to everything else. Many experiments were held to prove to the readers that our intuition deceives us.

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

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.

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

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.

Early studies have widely researched attention with selective processing (Driver, 2001). Broadbent (1958) filter theory of attention states that certain information does not require focal attention. It is based on certain stimulus attributes such as colour and shape (Friedenberg, 2012). A previous study carried out by Treisman and Schmidt (1982) proposes that when attention is diverted from a display of several figures, the participants incorrectly combine the features of colour and shape therefore increases the illusory conjunctions portrayed by the participants (Tsal, 1989). Another study by Shaw (1978) found that reaction time of participant to identify targets varied with the probability that a target would appear in a particular display location. These results indicate that different amounts of attention towards the targets are distributed to different positions in the visual field. However, Houck and Hoffman (1986) found that the feature integration of colour and orientation can sometimes be accomplished without attention (James et al.,

The article Sights unseen, written by Siri Carpenter, explores the phenomena of inattentional blindness. A common example which demonstrates this occurrence is when people are paying attention while driving, yet still manage to strike salient objects such as deer and other large animals. Despite common belief, if we do not pay careful attention, we may not see most of the obstacles in our path. Change blindness limits the brain’s ability to process visual information when the eyes are moving or vision is partially blocked from sight. For pilots, it is very important to prevent change blindness and inattentional blindness from interfering with their ability to safely transport goods and people. When we focus intently on details, we often become

I found chapter 4, Bounded awareness interesting because it brings to light the apparent choice people make to focus primarily on what they want to see. I think the PowerPoint presentation summarized it best; Bounded awareness is “In-attentional blindness to obvious information. 2.The failure to notice obvious changes in one’s environment. The tendency to focus on only a part of the problem at hand”. For example, I think the puzzle in the text of 9 dots illustrates this perfectly. I fell victim to this exact dilemma. I tried to stay within the boundaries of the nine dots and made the choice to place a boundary within the dots that did not exist nor was directed.

Psychologists often study the processes of stimuli through sensation and perception, and experimental research is tested for those who fail to perceive certain stimuli. Our perception of the world around us accounts for the method in which we perceive stimuli or fail to perceive it. Change blindness, inattentional blindness, absolute threshold, difference threshold, blind spot, and sensorineural hearing loss are often reasons why we do not recognize stimuli; we become unconscious to it.

I was not capable of paying attention to everything that changed. I was able to count the number of passes, and spot the gorilla. The curtain changing colors, and the player leaving went by totally unnoticed. I was way too focused on the number of passes than anything else. That is called selective inattention, when you are consciously aware, but "blind'' to all the little details. (Myers Page 81). I realized the gorilla through dual processing. I didn’t consciously see the gorilla, because I was fixated on the passes, but afterwards I remembered seeing one. (Myers Page 79). Research tells us that it is nearly impossible to multitask and do both with no problems. You physical can text or talk, but mentally, your brain cannot. "In areas vital

What is concept change? For example, the article A General Overview of Conceptual Change Research says, “It is important to understand that those who are involved in the conceptual change research domain are concerned about much more than simply altering a particular belief. If this were not the case, then it could be argued that conceptual change occurs every time someone changes his or her mind, or learns something new about a certain issue act” (Ruhf, 2003, P.1). This shows that a one person can have a change over time. Concept change doesn’t just happen over a day, it happens over a long period of time. For example, Concept change is like building a puzzle and it takes time. In the article in the beginning of this class I didn’t really

Many have experiences that seem to contradict the belief that, to one degree or another, we perceive everything in view and that our attention merely permits us to see some things in more detail than others. Almost everyone at one time or another has had the experience of looking without seeing and of seeing what is not there. The experience of looking without seeing is most likely to occur during moments of intense concentration or absorption. During these moments, even though our eyes are open and the objects before us are imaged on our retinas, we seem to perceive very little, if anything.” (Mack & Rock,

In my everyday college life, there are several ways in which my perception differs from that of my peers. These differences relate to our own experiences within developmental stages of life, each experience serves a specific role on how we perceive things everyday. Such as, the culture we were raised in, environmental factors, parental method, genetics, etc. Each of these factors influence sensory adaption, vision, auditory, touch, and taste. To begin with, sensory adaptation relates to the tendency to pay less attention to an unchanging source of stimulation”(151). In other words, we become less aware of the everyday sounds heard during our basic routines, rather instead we focus on the new or sudden noises that stand out. Another point to
