Document Summary

Part 1: doing two things at the same time. 2 difficult tasks = hard: e. g. , processing linguistic material + reading something else, people can"t pay attention to 2 scenarios (cid:523)in the overlapping video(cid:524) Potential distraction by background music not as great when there are no lyrics. Typing the shadowed verbal message, typing improved over practice: however, expertise may not translate to different situations. E. g. , expert driver but maybe not during a snowstorm. Difficult to explain practice effects with filter model. Broadbent tired arguing that the filter could be switched from task to task in rapid alternation. New metaphor: attention is like a resource. Attenti nl resource: difficult to define, like (cid:498)mental energy(cid:499, limited amounts, developed by kahneman (attentional resource model) Available sources depends on task complexity: more complex tasks use up more attentional resources. Availability resources depends on arousal: more aroused = more attentional resources.
