Attention And Change Recognition Psychology Essay

In recent years psychological literature has centered on attention and change detection. This newspaper examines the several key phenomena that comprise this process. Basically the premise asserts that we do not see or identify everything that takes place before our sight. Change Detection is situated after two key phenomenon: (1) Inattentional blindness and (2) Change blindness. Attention is becoming more intensively researched lately because of its links to cognitive psychology and neuroscience. The newspaper demonstrates the request of attention and change recognition from the lens of mindset. Research has mentioned that to be able to see change you must pay attention to it. (Rensink, R. A. 2002).


Attention may be defined as a subject area within the field of cognitive psychology. Consequently it refers to an activity about targeted information within our environment. It is the concept of awareness of those ideas that are taking place around you via our senses of look, sound and sensation. It had been the philosopher and Psychologist William Adam who located this into better perspective by proclaiming attention is to manage our mind; the ability to assimilate several things at the same time and the ability to filter out certain elements to focus on those that matter. (Anderson, J. R. 2004)

Attention is therefore a cognitive process that facilitates attention whilst being allowed to filter non-relevant subject matter. Lately this has received powerful research interest within the domains of cognitive mindset and neuroscience. Specific attention being focused on resources of the impulses i. e. sensory neurons and human relationships between other cognitive functions like storage area and vigilance. It has also been from the two key phenomena of inattentional blindness and change blindness. Attention has been extensively studied in college and educational settings looking at the behavioural habits of children. (Chavajay, P. 1999)

inattentional blindness & change blindness

The two key phenomena of attention are: (1) Inattentional blindness and (2) Change detection. With change blindness research workers have confirmed that changes can occur in an image minus the observers noticing or being conscious of that change. This triggers the phenomena of change blindness. The phenomenon of inattentional blindness is the shortcoming to observe a particular stimulus; we have been overloaded with lots of different stimuli working concurrently and therefore we cannot be aware of most of them. (Pashler, H. E. 1999)

inattentional blindness

One of the most famous assessments for inattentional blindness was the invisible gorilla test. This is carried out by two experts from the University of Illinois and Harvard School. The members were asked to review a video clip of a basketball game and focus on the number of times the ball was approved i. e. Floor and aerial goes by. The two teams of people used black and white T shirts to distinguish themselves. During the clip a female passes through the landscape putting on a gorilla halloween costume. After looking at the partiicipants were asked if indeed they noticed anything unusual and in most organizations 50% of the things claimed not to have observed the gorilla. The participant's attention was concentrated upon keeping track of the complex volume of passes and verification out those stimuli considered distracting to the concentrated effort. (Choi, C. Q. 2013)

Other good examples included an flight pilot and his team focusing on the sources of an unknown blinking light on the airplane control panel without noticing that these were rapidly approaching the ground resulting in a crash that wiped out over 100 people. (Ward, T. A. 2004).

change blindness

In the concept of change blindness experts have exhibited that even large changes in the confines of a picture can go unnoticed. This particularly in which a simultaneous event takes place like a brief disruption in visual continuity i. e. a retinal disturbance caused by the attention saccade. (O`Reagan, J. K. 2000).

Research investigations into change blindness have targeted upon links with working ram and eye moves. Working recollection may be good in the recall of a graphic but less reliable in relating smaller details as suitable to the image. This is particularly true of your complicated image. Our recollection can recall the general content of the image but is impeded on recalliung smaller levels of detail. This is demonstrated by a report completed by Rensink O`Regan and Clarke in the 1990`s. They got the attention to focus on a specific image. This is then followed by a blank glide prior to the image was cut back with a modification. The masking movements of the blank side was targeted at recreating the stimuls of the saccadic activity of the human eye and as such made it problematic for the person to identify the change in the image. (Grimes, J. 1996).

Attention is of paramount importance for the organism (eye) to detect change. To be able to allow this a aesthetic stimulus needs to be passed through the eye and passed to the brain. Therefore the eye must focus or attend on the change that is taking place. Years is also one factor and people older than 65 are a lot more prone to not notice changes in images.

Theoretical aspects

Broadbent referred to the human processing system and as such the first representation of attention. The important idea of the selective filtration system that is needed for information processing. He also asserted that the sensory store acquired a limited capacity to deal with the inputs and it was certain physical characteristics that allowed for stimuli to move the selective filter. This sometimes created a bottleneck and some stimuli is lost within this process (Friedenberg, J. 2012)

More modern perspectives like the views of Treisman presumed that Broadbent's model didn't fully explore all the findings. Essentially instead of the filtration Reisman thought humans possessed an attenuator that discovered subject matter by the physical properties attached to it consequently the messages are recognized but at a lesser order of magnitude thus it is received but not really blocked out. These contradicted Broadbent's theory because he asserted that folks were incapable of making truly significant connections. (Drivers, J. 2001).

Deutsch and Deutsch (1963) contrasted with Broadbents theory for the reason that they assumed a stage of consciousness was only achieved following the decision had been made to treat the precpt that had already been produced. (Deutsch J. A. and Deutsche, D. 1963). In 1973 Kahneman devised his capacity model of attenuation which asserted a person had a restricted capacity to peform practical applications (Friedenberg, J. 2011).

change detection

The idea of change recognition or change blindness pertains to when there is a visual change which change occurs without being noticed. The idea of an undetected difference between two images. Within the example below look at the two images of the Sphynx and the vacationers. There appears to be no difference to the two images but if you look more carefully so as to some trees and shrubs have been carefully erased behind the top of the Sphynx. The white edges indicate a blank slide that triggers a short disruption in aesthetic continuity i. e. a retinal disturbance caused by the attention saccade. It does not really impact the individual apart from expose that people do not necessarily visit a complete image. Certain levels of detail tend to be discarded or filtered out once we focus on quite concerns of the image. In this case people and the Sphynx, we aren't really concerned with the details of the background. (Enns, J. T. 2013).

Neuroanatomy of change blindness

Research has mentioned that aging, especially those over time 65, will be more vulnerable to areas of change blindness. It can be an early indicator to a more serious neurological disorder and the early onset of Alzheimer 's disease. Dr. A. L. Benton conducted lots of research tests in this area. He conducted lots of experiments that examined different stimuli and the impact on the behavior of the brain. Benton developed a number of important test situations including that of : Benton Visual Retention Test (BVRT) and Lines Orientation (JLO) test. (Matthew R. 2009. )

how individuals may be impacted

Change blindness can impact individuals in true to life settings. It may be an early sign of the starting point of Alzheimers disease. The problem is related to the PSI gene providing the hyperlink to change blindness. (Matthew, R. 2009). Other aspects relate with that of moles that develop over extended periods of time and could have the potential to turn cancerous. Most popular moles do not switch cancerous but risk does increase with age. (National Cancer tumor Institute, 2012).

Change blindness is rather a remarkable occurrence and may also be linked to attention deficit. It unveils from a cognitive perspective the limitations on conscious awareness and shows the differences in what we see and understand. Raising the knowledge of people in this field can help accentuate their awareness and help these to concentrate on change diagnosis. This improving storage area stimulation and assisting to eliminate the effects of consciousness. (Ambinder, M. S. 2005)

Practical applications

the eye witness testimony

When a topic is witnessing an strike the emphasis of attention is centred on the weapon instead of considering the clothes and face of the assailant. So eye-witness testimonies are not always reliable as stand-alone information and may bring about wrong convictions. A research study carried out at the College or university of Leicester centered on participants taking a look at a video of your burglary and 50 percent way through the image of the burglar was improved. 61% of the participants viewing the video tutorial failed to spot the identity transition. (Hine, S. 2007).

driving ability

Older drivers are often more prone to accidents than younger drivers. As the old motorists often notice change at a slower rate which can significantly reduce their response amount of time in terms of changes that impact the driver's central field of vision. This has increased the question of whether there should be an era limit for older drivers in order to reduce car accidents. Research in addition has shown that the positioning and relevance of change directly impacts what's observed whilst generating. (Horrey, W. J. 2005)

military commanders

Those train station commanders that are viewing various computer screens at the same time are inclined to change blindness. This is attributed to time delays on display refresh and the inability to verify changes which have occurred. Increased ergonomics and display design can help reduce the occurrence of problem and potential mistakes in decision making. (Linville, W. 2004).

INattentional blindesss

practical applications

Inattentional blindness ends in missing what others see as apparent. It is caused by the limited focus on focus on a particular area and be distracted.

the distracted driver

A driver utilizing a cellular phone in the car misses a red light at a junction and becomes involved with a serious motor vehicle accident. The mind is analysing the suggestions from the phone and providing responses for the conversation. The driving a car becomes a second objective and loss of attention occurs in the differentiation of the colours in the traffic equipment and lighting.

The pilot and the crop circle

A pilot charted a course to check out a new crop circle near Stonehenge. After discovering the site he made a landing to re-fuel before setting off on another trip that co-incidentally got him above the same crop circle site. On the next trip he seen another crop circle near to the first site. He swore that this had not been there 45 minutes before. A lot more plausible answer being inattentional blindness whilst he was focused after more important concerns in the cockpit and therefore he didn't spot the second circle. (Carroll, R. T. 2013)


The idea of 'Attention' within cognitive psychology is perhaps the key determinant that links back to you change blindness and inattentional blindness. As attention is selective it generally does not always filter in every of the images within a targeted visual field. The mind has a restricted capacity of information which it can process at a given time. Equally, this is easily distracted causing a loss of give attention to specific non-key occasions.
