Document Summary
Chapter 7 attention: phenomenon model hypothesis. Irrelevant information acts as noise that makes it difficult to attend to the important information: when irrelevant information overwhelms us, we get distracted. Box that flashes may not contain the star. If target is in cued location: attention will amplify the perceptual processing of the target (detected quickly). If target is in uncued location: target detected slower, since attentional spotlight is directed elsewhere: attention does not immediately rely on sight; attentional spotlight can still miss important information. Single filter model (donald broadbent): attentional filter selects important information based on physical characteristics; allows the information to continue on for further processing. Information that does not pass through the early physical filter is deemed unimportant : accepts less information than dual filter model. Dichotic listening paradigm: different messages in each ear; attended ear message must be shadowed back to the experimenter. Information going through attended ear goes to deeper processing: subjects remember nothing about unattended information.
