Document Summary
Analyzes the ways people process information about their world. Encoding: mechanism by which information gets into memory. Automaticity: ability to process information with little or no effort. Strategy construction: discovering new procedures for processing information. Strategies: gap filling spatial rotation anticipating consequences. Fast processing speed efficient mental operations. Changes in speed processing are assessed using reaction time tasks. Decline begins in middle adulthood; continues into late adulthood. For many everyday tasks, speed is unimportant because efficient strategies can compensate for slower reaction times and speed. Sustained attention: ability to maintain attention to selected stimulus over prolonged period; also called vigilance. Selective attention: focusing on a specific aspect of experience that is relevant, while ignoring others. Divided attention: concentrating on more than one activity at a time. Dishabituation: change in stimulus recovery of a habituated response/attention. Joint attention: individuals focus on same object or event and requires (~8 months)
