Quiz 3

Question 1

Selective attention

Answer 1

the ability to both focus on information of relevance AND inhibit or ignore information which is task-irrelevant

Question 2

Why is selective attention needed?

Answer 2

activation (in response to familiar cues and thoughts) is largely automatic, as it is spread through a network - spread is age invariant
too much information at once can reduce processing efficiency

Question 3

Age-related impairments in selective attention

Answer 3

Not decreased activation but decreased inhibition
Behavioral evidence: no difference in tasks with no distractors (no inhibition)
Neural evidence:

Question 4

Divided attention

Question 5

Dual tasking (increasing age effect)

Question 6

Role of expertise/experience in dual tasking

Question 7

top-down attention

Question 8

bottom-up attention

Question 9

exogenous attention

Question 10

endogenous attention

Question 11

dorsal attention network

Question 12

ventral attention network
