Document Summary
Attention: we need to identify what attention is, build a cognitive model which we can use to test our theories, and explain the hypothesis, unfortunately, attention covers a area of a wide range of topics. We cannot simply generate one theory or hypothesis in order to explain it. Attention: our conscious ability to attend to something that is relative to our goals. Attention implies withdrawal from some things in order to deal effectively with others. Selection: attending something (focusing) causes the object tot be inattentive to other objects in the surrounding, we may be attentive of something at first but may become inattentive if more important stimuli are present during a time. Some stimuli have a stronger grasp towards our attention than others do. Irrelevant background information makes it increasingly difficult to attend and identify the important information: we usually turn radio down when we are driving and need to make important decisions.
