Document Summary
Attention refers to characteristics associated with: consciousness, awareness, cognitive effort characteristics on the. We are particularly interested in the limitations associated with those: simultaneous performance of multiple skills, detection of relevant information in the performance environment. When we simultaneously perform multiple tasks (e. g. driving a car, listening to a. Cd, and talking with a passenger), we sometimes: experience no difficulties in performing all the tasks, but, cannot do all the tasks as well as we would like. Why: answer relates to attention as a performance limiting factor. Filter theories: (aka bottleneck theories: difficulty doing multiple tasks simultaneously because of inability to serially process multiple stimuli (see fig. Resource capacity theories: difficulty doing multiple tasks simultaneously because of limited availability of resources needed to carry out tasks. Simultaneous successful performance of multiple tasks can occur when resource capacity limits not exceeded: 1. Propose one central (i. e. cns) source of attention resources for which all activities compete.
