How does selective attention differ from sustained attention?
ABoth refer to filtering out novel stimuli before they reach the cortex
BSustained attention picks limited stimuli, selective attention focuses for hours
CSelective attention picks limited stimuli, sustained attention maintains focus over time
DBoth refer to dividing focus equally between two simultaneous tasks
Answer & Solution
Correct answer: C. Selective attention picks limited stimuli, sustained attention maintains focus over time
1. Selective attention is described as the process by which certain stimuli are picked from many.
2. Sustained attention is described as the ability to maintain attention on a task for longer durations.
3. The same passage notes that sustained attention is also called vigilance.
4. Distractor 2 swaps the definitions, while distractors 3 and 4 conflate both with divided attention.
5. Hence the correct contrast is selection of limited stimuli versus maintenance over time.
