Document Summary

Selective attention: attending to relevant information and ignoring irrelevant information: sometimes we fail to notice information that we haven"t selected for our attention. Controlled processing: needed for activities we must consciously attend to if we are going to execute them properly (stroop task: ink color naming task) Automatic processing: needed for activities that do not require attention to run smoothly (stroop task: word reading) Attentional blink: rapid serial visual presentation, participants have to identify targets among distractors, using attention takes time. If two targets are presented within 500ms, the second one won"t be identified. Inattentional, a failure to see something in a display that is right there (attention and perception) vs change blindness, a failure to detect change in a display (attention and memory) Participants aren"t expecting a target but are looking in the general area, make sure it is in their visual field: 2. Participants are using attention resources for some task: over a series of experimental trials, a.
