Document Summary
Arousal/vigilance: a global state of wakefulness/state of being alertly watchful. Selective attention: the act of differentially processing specific sources of information at the expense of other sources. There"s no way to effectively process all of the information in our environment at once. Goal-directed: a form of attention guided by current instructions or intentions ( top-down or endogenous) Stimulus-driven: capture of attention via capture by salient or rare events (exogenous) Looking for a target in a display containing distracting elements. Set size: the number of items in a visual search display. It doesn"t matter how many items you show, the target pops outs . Goal-driven search: reaction times increase linearly with the set size of the display. Cue: stimulus indicating what/where an additional stimulus might be. Distractors: non-target stimuli often included to increase difficulty/decrease performance. Inhibition of return: impairment of accuracy and speed of target processing of 500-3000 msec following an exogenous cue.
