61
What is sustained attention?
Ability to maintain concentration or focus towards stimuli over a given time frame. Often referred to as 'vigilance'.
62
What are problems with sustained attention evident by?

What are problems with selective attention indicated by?
Distractibility or difficulty disengaging from competing environmental stimuli (auditory or visual).
66
How do we assess selective attention?
Behavioural observation (is the person easily distracted?) and various cognitive tests.
67
What is alternative attention?
The ability to shift the focus of attention from one aspect of a task to another - also related to mental flexibility.
68
What are some problems with alternating attention evident by?
The person getting stuck on one task and neglecting others or starting tasks, leaving the and failing to return to complete them.
