Document Summary
Attention- process that enhances some info for further processing and inhibits other info to set aside. Types of attention: selective attention- people are limited in their capacity to process incoming info, therefore need to be able to focus on info that is relevant to their goals. Can be selective in space (processing info in one location may cause you to miss other info) or time (when new info is rapidly presented, processing some of it may cause you to miss other info) Attention seems to be guided by top-down processing. Exogenous attention- salient external stimulus that drives attention (bottom-up) Endogenous attention- covert, internally controlled, driven by goals (top-down: sustained attention- takes place over a prolonged period of time, so that you keep in mind the goal you"re attempting to achieve. Losing sustained attention- lose focus and get diverted to an irrelevant task: divided attention- doing 2 activities at the same time.
