Document Summary

Selecive atenion: capacity to respond to certain simuli selecively when several occur at once. > salience: does it stand out? ( botom up process) > expectancy: where do we expect something to happen? (top-down) > value: what is important to pay atenion to? ( top-down) > efort: does it take efort to pay atenion to? (botom up process) Divided atenion: is the ability to perform more than one task at one, while simultaneously atending to each ( mulitasking ) Three processes happen concurrently : botom-up free analysis, uniizaion (gathering all informaion and clumping them together as groups), top down processing. > use familiar fonts, icons, and use whole words instead of abbreviaions. Working memory: relaively transient and limited to holding a small amount of informaion that may be rehearsed or worked on by other cogniive processes. Informaion stored in working memory decays over ime unless it is periodically reacivated or rehearsed. > confusability: how similar is it to other informaion.
