rapid serial visual presentation
Rapid serial visual presentation is an experimental model frequently used to examine the temporal characteristics of attention. The RSVP paradigm entails participants to look at a continuous presentation of visual items which is around 10 items per second. They are all shown in the same place. The targets are implanted inside this stream of continuous items. They are separate from the rest of the items and can be called distracters. The distracters can either be a color change or it can be letters that are among the numbers.
==Overview==
There is a delay of several hundred milliseconds. A person might be asked to identify numbers in a string of letters which are shown one by one. The first number which is an important target, would be caught by the person, however, the second number flashed seconds later might not be observed. There are a number of theories to explain how and why this works and studies have explored its limitations and parameters to learn more about visual perception.
The brain deals with a quick stream of incoming information at all times. With the attentional blink, the brain has to distribute its attentional resources to comprehend, interpret, and store the information properly. The human brain is able of processing complex tasks, but it has restrictions. The attentional blink is an illustration that has a significant insinuation for individuals who work in environments where they are usually swamped with information. An example of this is an airport baggage screener who might see a knife in one bag, but misses a second knife in another bag that is right behind the first bag. The failure to recognize the second target is because of the attentional processes that are linked with the identification of the first target.
