Document Summary
Cognition in adult rehabilitation: attention, memory, executive function. Attention: 5 levels, focused attention (alertness, orienting) ability to perceive individual pieces of information, sustained attention. Concentration & vigilance - ability to continue at a task over period of time: selective attention ability to avoid distractions. External- extraneous noise: alternating attention ability to shift focus and alter focus between tasks, divided attention ability to respond to multiple tasks simultaneously, rat- resource allocation theory. Cognitive processing has both limits in quantity and ability to allocate those resources across multiple tasks. Involves both controlled and automatic processing: controlled processing slow, effortful, requires much cognitive resources (rat) learning new task; problem solving serial processing (one at a time, automatic processing fast; requires minimal cognitive resources. Also used by physiologic tasks (breathing, heart rate, postural adjustments, temperature) Assessing attention: many standardized tests available (for all levels of attention); most administered by neuropsychologists, sustained attention: digit span (wechsler memory scale-revised, selective attention:
