Document Summary

Cue: a stimulus that might indicate where [or what] a subsequent stimulus will be. Cues will be valid [correct information], invalid [incorrect[ or neutral [uninformative] A simple probe detection experiment > posner cueing paradigm. Stimulus onset asynchrony [soa]: the time between the onset of one stimulus and the onset of another. Endogenous cues take more time than exogenous cues to attract attention. Amongst endogenous cues, gaze and arrows work best [bottom-up] With symbolic cues, we need to process the cue, so if there is a 100ms soa we will not benefit from the cue. "spotlight" model of attention :attention is restricted in space and moves from one point to the next. Visual search: looking for a target in a display containing distracting elements. o o o. Distractor: in visual search, any stimulus other than the target. Set size: the number of items in a visual search display.
