A continuous performance task, continuous performance test, or CPT, is any of several kinds of neuropsychological test that measures a person's sustained and selective attention. Sustained attention is the ability to maintain a consistent focus on some continuous activity or stimuli , and is associated with impulsivity .
Two early examples of this include the Executive Process Interactive Control model (EPIC; Kieras, Wood, & Meyer, 1995; Meyer & Kieras, 1997) and the ACT-R (Byrne & Anderson, 1998). A model of a task in a cognitive architecture, generally referred to as a cognitive model, consists of both the architecture and the knowledge to perform the task.
For example, subjects whose task performance is well correlated for a successive task may exhibit a poor performance correlation for a simultaneous task. Conversely, subjects performing similar monitoring tasks, such as radar versus sonar target detection, can be expected to exhibit similar patterns of task performance.
[8] Whatever the cause of the performance differences between the n-back and other assessments of working memory, some researchers stress the need for further exploration of the construct validity of the n-back task. [7] Performance on the n-back task seems to be more closely correlated with performance on measures of fluid intelligence than it ...
Whereas task performance describes obligatory behaviors, contextual behaviors are behaviors that do not fulfill specific aspects of the job's required role. Citizenship behaviors are defined as behaviors which contribute to the goals of the organization through their effect on the social and psychological conditions. [ 6 ]
Task Structure, referring to the extent to which group tasks are clear and structured. Leader Position Power, referring to the power inherent in the leader's position itself. When there is a good leader-member relation, a highly structured task, and high leader position power, the situation is considered a "favorable situation."
Performance increases on simple tasks because the performers focus their attention on the new stimuli, instead of the irrelevant stimuli that is characteristic of simple tasks. Performance decreases on complex tasks because the performers focus on the distracters, but also need to focus on the relevant stimuli that are characteristic of complex ...
A critical task analysis, for example, is an analysis of human performance requirements which, if not accomplished in accordance with system requirements, will likely have adverse effects on cost, system reliability, efficiency, effectiveness, or safety. [5] Task analysis is often performed by human factors and ergonomics professionals.
