Document Summary
Lecture four, attention, 2060u cognitive psychology, matthew shane, october. Attention: process of concentrating on specific features of the environment or on certain thoughts or activities. Selective: excluding of other features of the environment. Both overt and covert: we can consciously attend to information but some information grabs our attention. Dichotic listening study 1: one message is presented to the left ear and another to the right ear, participant shadows one message to ensure he is attending to that message. Can we completely filter out the message to the unattended ear and attend only to the shadowed message: participants could not report the content of the message in unattended ear. Selective attention: ability to focus on one message and ignore all others, we do not attend to a large fraction of the information in the environment, filtering out some information and promoting other information for further processing. Filters message before incoming information is analyzed for meaning.
