Attention is among the most important of our cognitive functions. Although it is not as heavily researched as perception is, attention affects almost all of the other cognitive functions.
Attention can be defined as "selecting some information for further processing and inhibiting other information from receiving further processing."
Failures of Selection: We can fail to attend to information when there is a lot of information present and you are simply not capable of noticing at all at once. Failure can also occur when information arrives rapidly.
These two upcoming videos demonstrate a failure of selection known as Change Blindness, failure to detect changes in the physical aspects of a scene. Enjoy!
