Document Summary
5 functions of attention: focusing: limits the number of items being processed. This is a big challenge for students: action selection: choosing an action from among a set of possibilities. There"s only so much that we can do with our given body. Two types of attention defined according to what makes us attend: exogenous attention: an automatic deployment of attention to a salient aspect of the environment (-exo: source is coming from the outside). An outside force that pulls our attention towards it. The way we direct our attention is fast and obligatory: endogenous attention: conscious deployment of attention to a behaviourally important target (-endo: coming from within). This is top-down, something we"re intending to attend to. 2 ways: overt attention: with eye movement. Saccades are the directed eye movements; rapid and jerky movements from one fixation to another. Initially guided by bottom-up, then top-down processes come in.
