Document Summary
Attention: any of very large set of selective processes in brain. Sustained attention: watching pot to note movement of water begins to boil. Selective attention: form of attention involved when processing is restricted to subset of possible stimuli. Use attentional mechanisms to give priority to one sense over others. Posner subject in experiment fixates on central point (*) and after variable delay, test probe appears in one of. All subject needs to do is hit response key as fast as possible when probe appears. Reaction time: measure of time from onset of stimulus to response. Cue: stimulus that might indicate where (or what) subsequent stimulus will be. In typical experiment, cue might be valid on 80% of trials and invalid on remaining 20% Stimulus onset asynchrony (soa): time between onset of 1 stimulus and onset of another. In cueing experiment, attention starts at fixation point and ends up at cued location.
