Attentional blink

There are numerous stimuli in our environment at any one given time and individuals use attention to filtering out various stimuli that the individual does not require. Nonetheless, there are situations where you cannot concentrate no matter how hard you try to pay attention. One circumstance includes the time when the visual display stimulus is in close succession the attentional blink affects the recognition of an individual. Attentional blink takes place when there is Rapid serial visual representation (RSVP) the presentation of stimuli may be pictures, digits as well as pictures where there is the presentation of items at the rate of about six to twenty item within a second (Martens & Wyle, 2010).

An attention blink usually deters the concentration of an individual where they can spot the first target but not the second target in the same sequence of items. In most cases, the attentional blink will occur when the second target comes between speeds of 180 to 450 milliseconds after their preceding targets. This occurs when the attention for identifying the second target becomes insufficient at the perceptual level or working memory as well as response selection level. When presenting a stimulus to an individual in that instance the brain’s cognitive process is usually busy registering the first target, therefore, taking the attention capacity consequently leading to the loss of sight of the preceding target. In addition, the attentional demand increases since the second target undergoes masking by the bordering distracters, this, therefore, prematurely interrupts the perceptual representation processing of the second target (Choi et al., 2012).

It is quite difficult to do away with attentional blink. However, studies have shown that meditation is critical in ensuring that an individual reduces the duration of the attentional blink. The individuals that are mediators by training can overcome the attentional blink. There are also scientific ways of eliminating the attention blink it includes training an individual by replacing the second target that is, for instance, white in color with an outstanding such as the color red. After restoring the color of the second target, an individual can identify it within the same speed succession. When the second target is reverted to the original white color, the observers are able to identify the second target at the same speed after several months there is a repeat of the experiment on the same individual where they are able to retain the brain training (Martens & Wyle, 2010).

Attentional Blink Demonstration

An individual’s Cognitive mechanism can uptake a restricted quantity of information. In numerous situations, there are those stimuli that are processes while other is not. Cog Log attention blink experiment explores particular attention properties in the presence of fast-changing stimuli. The experiment demonstrates that when an individual’s attention focus is on a particular stimulus there will be no focus for the subsequent stimulus. The research uses letters, where their presentation is in quick succession, where one letter overwrites the previous letter. The task of the observer is to look at the sequence and indicate appropriate letters within the sequence. The finding obtained from the analysis is that the identification of the second letter is cheap when it quickly trails the first target. This is because an individual sees the first letter and attends to it; therefore, if the second letter appears during this time the person is unable to identify the letter (Martens & Wyble, 2010).

In the Cog Lab experiment for identifying attentional blink the targets used in the demonstration are letters. However, one may replace the target with different stimuli such as symbol, and pictures as well scenes that capable of inducing attentional blink. The resource channel required for target identifications brings about the difference in effect of various targets on the attentional blink. For instance, if the target is a face or a symbol these targets will use neural networks that are independent consequently realizing different cognitive, as well as perceptual acts. There is a circumstance where there is an elimination of the attentional blink especially when the different targets are in use, for instance, when the first target is a symbol, and the second target is a face, individual were able to identify the second target. Furthermore, studies have shown that faces are more conspicuous as opposed to other objects, in many cases a face image create a pop out phenomena on individual’s cognitive process (Choi et al., 2012).

Occupations Prone to Attentional Blink

Personnel of particular occupations may be prone to attentional the blink than others. For instance, other motorists or pedestrians that are constantly on the road may deter truck drivers, therefore, making the truck drivers more likely to attentional the blink in the course of their driving. The attentional blink may cause the driver to cause an accident that may cause injury and in some instances loss of lives. Bank tellers are prone to attentional blink. These individual are constantly handling money in the process of counting money that a customer has brought to deposit for payment, respectively attentional blink may sometimes occur. In miscounting the money received, it will mean that the business may sometimes incur particular losses due to that attention lapse (Martens & Wyble, 2010).

Occupation in traffic control makes its personnel prone to attentional blink. For example, the personnel that control air traffic usually track movements of planes ensuring that the traffic flows smoothly. Sports announcers are prone to attentional blink especially in instances where competitors are in a race. When an individual in a sports competition and are crossing the finish line, they are usually very fast causing attentional blink to the sports announcer that are observing careful individuals that are crossing the finish line. The attentional blink in this instance may cause the announcer to miss the individual crossing the finish line after the winner hence announcing the wrong individual in second place, such a mistake may bring about confusion and may cause fun to become rowdy (Martens & Wyble, 2010).

Heads-up Display (HUD)

Heads-up display is a transparent display that usually presents data without the need of the users to look away from a designated viewpoint. Numerous motorists are using the HUD as a safety tool; this is because it permits drivers always to maintain their eyes on the road. It is a safe replacement from the dashboard display of the distance travelled, speed, fuel as well as time travelled, looking at the dashboard means the driver will have to travel blind for a few meters making the driver prone to accidents. In addition, heads-up display unit usually shows direction that aid the driver it is paramount especially in bad weather consequently saving various number of lives (Abdollahi & Leing, 2014).

The heads-up display consists of a projector, a combiner, as well as video generation computer; these components are responsible for producing an image in parallel light. The image display is on the windscreen of the car. The images in advanced HUD consist of numerous colors as well as clearer images that cover a wider surface are of the windscreen. Despite the various benefits ofheads – up display unit, it may also cause individual to become to the attentional blink. Since the HUD is in the view of the driver, it may draw his/her attention consequently leading to the attentional blink that may cause the driver to cause an accident (Martens & Wyble, 2010).
