Document Summary

Attention- any of the very large set of selective processes in the brain. Selective attention- form of attention involved when processing is restricted to a subset of the possible stimuli. Reaction time (rt)- measure of the time from the onset of a stimulus to a response. Cue- stimulus that might indicate where (or what) a subsequent stimulus will be. Stimulus onset asynchrony (soa)- time between the onset of one stimulus and the onset of another. The cue has to stay for a minimum period of time for it to work. Spotlight model- attention is restricted in space and moves from one point to the next. Zoom lens model- attended region can grow or shrink depending on the size of the area to be processed. Visual search- looking for a target in a display containing distracting elements. Distractor- in visual search, any stimulus other than the target. Efficiency of visual search is quantified as average rt as a function of set.
