What is the history of research on change blindness?
The laboratory study of change blindness began in the 1970s within the context of eye movement research. George McConkie conducted the first studies on change blindness involving changes in words and texts; in these studies, the changes were introduced while the observer performed a saccadic eye movement.
What are some of the best studies on change blindness?
One of the most famous studies on change blindness took place shortly after the study on continuity errors. DJ Simons and Daniel Levin published this study in 1998, called “Failure to detect changes to people during a real-world interaction.”

DJ Simons and Daniel Levin published this study in 1998, called “Failure to detect changes to people during a real-world interaction.” This study became famous because it showed that change blindness doesn’t just occur in a 2D space. We experience change blindness “out in the real world,” too.
What is ‘change blindness’ in psychology?
The chosen topic area for the class I was working in, was a phenomenon known as ‘ change blindness ’ and it is one area of psychology that is slightly under-researched, in particular in relation to more recent years. Change blindness refers to when people fail to detect relatively large changes in visual scenes.
What is the concept of change blindness?
Change blindness is a phenomenon of visual perception that occurs when a stimulus undergoes a change without this being noticed by its observer. To date, the effect has been produced by changing images displayed on screen as well as changing people and objects in an individual's environment.
Why do we have change blindness?
The key factor in causing change blindness appears to be the effective removal of the local changes that accompany a change, either by being overwhelmed by global motion signals, or else by hiding them altogether. But why should this be? The prevailing explanation is that visual attention is needed to see change.
How common is change blindness?
Levin, Momen, Drivdahl, & Simons (2000) 83% of the participants predicted that they would notice these changes.
Is change blindness top down?
With change blindness the two competing views are described as the top-down hypothesis and the bottom- up hypothesis, referring to what it is about the change of a scene that grabs our attention. Top down theories involve our understanding of the context of a scene.
What did Hermann Ebbinghaus do?
Hermann Ebbinghaus, (born January 24, 1850, Barmen, Rhenish Prussia [Germany]—died February 26, 1909, Halle, Germany), German psychologist who pioneered in the development of experimental methods for the measurement of rote learning and memory. Ebbinghaus received a Ph. D.

How does change blindness affect driving?
Discussion. Experiment 1 found that showing participants a change blindness demonstration during a driving course had an impact on their self-rated observational skills. Participants reported that they found it to be more difficult to “spot important visual information” after they had viewed the demonstrations.
How does Ajax reduce the effect of change blindness?
It happens because when the event gets changed frequently. The ajax will do these types of events. It loads the effects frequently and it also overcomes the page loads. It means that when there is an ajax called then the contents of the page get change without reloading of the page.
Does change blindness involve the eyes or brain?
During change blindness everything about your visual system is intact and functioning. All of the information enters your visual system in the same way and is processed by the retina the same way; it even enters primitive parts of the brain in the same way.
What does change blindness research reveal about consciousness?
by change blindness tell one absolutely nothing about what a person is conscious of. They reveal nothing about perceptual experience. They reveal something, perhaps, about what a person knows or doesn't know, what she thinks or doesn't think, but nothing about what she sees or fails to see.
Attention: Change Blindness and Inattentional Blindness
CB and IB both involve a failure to perceive things that are easily seen once noticed, and both are believed to be due to a lack of attention. It is therefore likely they are related. But exactly how?

Visual Attention While Driving
Van Gompel, Fischer, Murray, and Hill (2007) introduced their book on eye movements with a historic perspective on the idea that the eyes provide access to the inner workings of the mind and brain. They quote De Laurens (1596) as referring to the eyes as “windowes (sic) of the mind” (p.
What is change blindness?
According to a 2005 study published in the journal Trends in Cognitive Science, the term change blindness "refers to the surprising difficulty observers have in noticing large changes to visual scenes." 2
Why do psychologists use the term "change blindness"?
Psychologists use the term change blindness to describe the tendency people have to miss changes in their immediate visual environment. 1 . Here's why change blindness happens as well as the effect it can have on how you perceive and interact with the world around you.

What was shown during a brief blank interval in the visual scene?
Participants were shown an image that was changed during a brief blank interval in the visual scene. The researchers found that the participants found it more difficult to detect changes when there was a brief break in the visual scene. 4
Why do people think they would see the changes?
"One reason people think they would see the changes may be that they know from past experiences that changes that occur in real life are usually easy to see.
What are the factors that influence change blindness?
There are other factors that could influence change blindness, including attention, age, how objects are presented, and the use of psychoactive drugs. Researchers have also found that shifting a person's attention, such as by causing a distraction, leads to increased change blindness.
What is change blindness?
Change Blindness is when people fail to notice visual changes in their environment. These changes could be glaringly obvious if you’re paying attention to them. But if you’re not paying close attention, or something else catches your eye, these “obvious” changes could go unnoticed.

Occipital Lobe
Visual attention refers to the ability to prepare for, select, and maintain awareness of specific locations, objects, or attributes of the visual scene (or an imagined scene). The focus of visual attention can be redirected to a new target either reflexively or through the purposeful effort of the observer.
Attentional capture and inattentional blindness
Recently, Wolfe and Horowitz have raised a potential alternative explanation for findings of change blindness and inattentional blindness (Refs a,b ). They suggest that failures to report changes or unexpected objects reflect not a failure of perception or of attentional capture, but a failure of memory.
Why visual attention and awareness are different
In other words, we are ‘conscious’ of many inputs but, without attention, this conscious experience cannot be reported and is quickly erased and forgotten. Figure 1 describes a psychophysical experiment in support of this view. We have seen that cueing the item that might change in a display of many objects protects from CB ( Fig. 1b ).
What is change blindness?

How does change blindness work?
Early experiments with change blindness focused largely on memory and perception when viewing pictures. For example, a person might be shown a photograph of a street scene in Egypt and told to memorize the image. Following that, they would be shown the same picture with certain elements added or taken away and asked to identify what's different. Very often the individual could recall the larger aspects of the picture but couldn't recognize the smaller changes.
What is change blindness?
Change blindness refers to when people fail to detect relatively large changes in visual scenes. For example, it has been shown that people can miss large animals being present in some parts of visual scene, such as a gorilla, and it has also been shown that even changes of faces can be difficult to detect within scenes.
Why do people miss a change in the background?
If an item is placed in the background of a scene in comparison to the foreground then this again can cause a person to miss a change, as people tend to pay attention to the things that are closest to them.
