What is selective attention?

Answer 7

The ability to select and attend to relevant stimuli, while ignoring irrelevant stimuli

Question 8

T or F: Attention involves the ventral stream of attention, not the dorsal stream.

Answer 9

Orienting a person in time and space

Answer 10

Maintaining vigilance in the environment

Answer 11

Top-down processing and orienting attention

Question 12

The superior colliculus is important for which aspect of attention?

Answer 12

Shifting attention towards external cues

Question 13

The pulvinar of the thalamus is important for which type of attention?

Answer 13

Reflexive attention

Question 14

The temporoparietal junction is important for which aspect of attention?

Answer 14

Reorienting attention

Question 15

Do individuals with ADHD show decreased white matter or grey matter in structural MRI studies?

Answer 15

White matter

Question 16

Bilateral damage to the posterior parietal and occipital cortices cause which disorder of attention?

Answer 16

Balint’s Syndrome

Question 17

Simultagnosia, optic ataxia, and oculomotor apraxia are characteristic of which disorder of attention?

Answer 17

Balint’s Syndrome

Question 18

What is simultagnosia?

Answer 18

The inability to recognize more than a small selection of objects at once

Question 19

What is optic ataxia?

Answer 19

Difficulty locating objects in space

Question 20

What is oculomotor apraxia?

Answer 20

Impairments in voluntary eye movements

Question 21

What is neglect?

Answer 21

Impaired ability to recognize objects or events in the hemisphere opposite to the lesion

Question 22

Damage to which brain area is most closely related to neglect?

Answer 22

Right parietal cortex

Question 23

What is the cocktail party effect?

Answer 23

The ability to give covert attention to one stimuli while maintaining overt attention to another

Question 24

What is the bottleneck in information processing?

Answer 24

A stage where not all inputs can gain access or pass through

Question 25

Does distracted driving cause a shift from the posterior attention system to the anterior attention system, or from the anterior to posterior?

Answer 25

Posterior to anterior

Question 26

Is the posterior occipital-parietal attentional system involved in automatic and practiced visuospatial abilities or multitasking and divided attention?

Answer 26

Automatic and practiced visuospatial abilities

Question 27

Are the anterior cingulate and frontal lobe involved in automatic and practiced visuospatial abilities or multitasking and divided attention?

Answer 27

Multitasking and divided attention

Question 28

What is it called when someone overtly attends a stimulus but doesn’t process the information?

Answer 28

Inattentional blindness

Question 29

What effect does the automatic orienting system have on attention?

Answer 29

After covert attention causes a change in attention, there is an inhibitory after effect, making the same stimulus less likely to capture arrention is the near future

Question 30

T or F: If a stimulus is salient and relevant, voluntary attentional mechanisms can be engaged to rapidly override the inhibition of reflexive return.

Answer 30

True

Question 31

What does the feature integration theory suggest?

Answer 31

That the visual system can parallelly process multiple features when being attended to.

Question 32

T or F: There is limited evidence for object based attention.

Answer 32

False

Question 33

Does the dorsal attention network reflect goal-directed or stimulus directed attention?

Answer 33

Goal-directed

Question 34

Does the ventral attentional network reflect goal-directed or stimulus directed attention?

Answer 34

Stimulus-directed

Question 35

Is the ventral attentional network lateralized to the right or left hemisphere?

Answer 35

Right

Question 36

T or F: The dorsal attention network is lateralized to the left hemisphere.

Answer 36

False. It’s bilateral.
