Document Summary
Memory: nervous system"s capacity to acquire and retain usable skills and knowledge. Attention is limited, and performance suffers when attention is divided amongst too many tasks or if a task is particularly difficult. Automatically identify primitive" features: colour, shape, orientation and movement in an environment. Parallel processing: systems all process information at the same time, can attend selectively to one feature by effectively blocking further processing of others. Visual/feature search tasks: participants look for targets that differ from others by only one feature, other objects in display are distractors, unique target pop out. Searching for two features is serial (looking at more than one stimuli at a time) and effortful (takes longer and requires more attention) Conjunction task: stimulus you"re looking for is made up of two simple features. Cocktail party phenomenon: you"re capable of focusing on one task, but after a particularly pertinent stimulus (e. g. hearing your name) can redirect your attention.
