Attention 3

Question 1

Change blindness

Answer 1

When change in visual stimulus is introduced and goes unnoticed

Question 2

Surprisingly difficult to detect changes

Answer 2

With change blindness

Question 3

There are certain conditions where

Answer 3

Change blindness is more likely

Question 4

What do change blindness and inattentional blindness have in common

Answer 4

Failure to perceive things easily seen once noticed, both due to lack of attention

Question 5

If change/inattentional blindness occurs due to early selection

Answer 5

The stimulus should never be perceived

Question 6

If it occurs due to late selection

Answer 6

The stimulus might be perceived but not remembered

Question 7

Differences between change blindness and inattentional blindness

Answer 7

Memory plays a role in change blindness but not inattentional blindness, and change blindness can occur even if finding the change is the actual task but inattentional blindness typically occurs when observer is performing another task

Question 8

Four main lobes

Answer 8

Frontal lobe, parietal lobe, occipital lobe, temporal lobe

Question 9

Frontal lobe is located

Answer 9

In the front

Question 10

Parietal lobe is located

Answer 10

At the top

Question 11

The occipital lobe is located

Answer 11

In the back

Question 12

The temporal lobe is located

Answer 12

At the bottom

Question 13

Large scale

Answer 13

Areas in different lobes of the brain

Question 14

Attentional

Answer 14

Activity modulated by attention

Question 15

Networks

Answer 15

Areas tightly interconnected by neuronal pathways, often activated together

Question 16

Two major attention network

Answer 16

Dorsal attention network and Ventral attention network

Question 17

Dorsal attention network main components

Answer 17

Frontal eye field and intraparietal sulcus

Question 18

Ventral attention network main components

Answer 18

Ventral frontal cortex and temporoparietal junction

Question 19

Dorsal attention network roles

Answer 19

Top down control, goal driven orienting, left and right hemisphere

Question 20

Ventral attention network

Answer 20

Bottom up control, stimulus driven, mainly right hemisphere

Question 21

Spatial neglect is caused by

Answer 21

A damage to the ventral attention network

Question 22

Spatial neglect is almost always on

Answer 22

The left side

Question 23

Spatial neglect patients are usually

Answer 23

Unaware of deficit

Question 24

Extinction

Answer 24

Typically seen in recovering patients, one stimulus on neglected side is perceived and two stimuli on non neglected side is perceived

Question 25

Extinction suggests that

Answer 25

Spatial neglect is not a visual deficit but an attentional deficit

Question 26

Neglect should be considered __ not a perceptual deficit

Answer 26

Attentional

Question 27

Neglect can affect _____ as well as perception of space

Answer 27

Imagination

Question 28

Spatial neglect is

Answer 28

Quite frequent, 40% of patients with right hemisphere lesions

Question 29

In about 10% of patients, ____ ______ even after more than 6 months

Answer 29

Severe deficits

Question 30

In clinical setting, ____ _____ is often not correctly diagnosed

Answer 30

Spatial neglect

Question 31

If spatial neglect is not diagnosed,

Answer 31

There are no rehabilitative efforts

Question 32

Ideally there is a standardized assessment for spatial neglect

Answer 32

By neuropsychologists
