Problems are solved by attentional processing

Consideration must process a wide range of information that could limit permanent senses and memories. Ambiguous and external information can not only lead to incorrect answers, but also to extend the time to respond. This problem not only arises for the system as a whole, but also for special modules to participate in cognitive processing, such as modules which are specialized in the processing of location information and shape information stimulus side and modules which are specialized in the extern configuration as an internal act of the response side.
Another problem to be solved for attention is to extend the selection of information from the senses and memory arrays in a certain expectation of action or event, or just for its own sake, without having to predict a future action or event. But under certain circumstances, sustained attention can be counter-adaptive, as in the example of animals just to eat there while being chased by a predator. Therefore, to be adaptive, attention process should be subject to interrupts. An interrupt can be considered as priority attention to the direction of choice
a particular class of events. The best examples interrupts sudden change in luminescence or sounds produced by the sudden appearance of things, which often signal very important event in the lives of animals and humans. Something which then signal his presence by an abrupt onset may be the target of sustained attention, but attention to this matter, in turn, become vulnerable to interruption by the sudden change in the sights and sounds of other things.
The three problems just described, limiting the processing of certain inputs, extension of limitation, and the interruption of such limitations, the obstacles that confront an engagement process as it is to do its job and an elective part of the processing system does not drain, but they seem to be one of the most important ones. Other problems to his attention early termination of the selective processing of something is done once a suitable policy (for example, with regard to the identity or color); rapid shifts to another object, preferably a processing object that has not yet been scanned selectively, as appears to be happening at high speed search and read quickly, smoothly; and rapid shifts between two or more tasks that require simultaneous control.
