Lecture 11 Flashcards
(30 cards)
What is one benefit of attention in perception?
a) It allows you to ignore all incoming information.
b) It boosts behavioral sensitivity, making you more likely to spot the relevant object class.
c) It decreases activity in relevant brain systems.
d) It only works for auditory stimuli.
B
What happens to brain activity in relevant systems when attention is directed towards an object, like a face?
a) It decreases.
b) Blood flow is enhanced, and activity in areas like the fusiform face area is boosted.
c) It remains unchanged.
d) It is inhibited.
B
When subjects attend to one object or position, what can they be blind to?
a) Objects of the same type.
b) Other objects and unexpected events.
c) Sounds and smells.
d) Their own movements
B
What is a reason why the world appears static when our eyes move?
a) Our vision is enhanced during eye movement.
b) The objects themselves are not moving.
c) Our brain ignores all movement.
d) Our vision is turned off during eye movement.
D
What is “change blindness”?
a) The phenomenon where changes in the world that occur during a saccadic eye movement go unnoticed.
b) The inability to see colors.
c) The inability to recognize faces.
d) The perception of constant motion.
A
In the experiment where a person’s identity changed while a door was carried, what percentage of observers did not notice the change?
a) 10%
b) 25%
c) 50%
d) 90%
C
What can disrupt spotting image change?
a) Brighter lighting.
b) A flash.
c) A longer viewing time.
d) Increased focus.
B
When do we tend to miss changes in an image?
a) When they happen quickly.
b) When they are very obvious.
c) If an irrelevant transient (e.g., flash, saccade) occurs between the original and new forms.
d) If they occur in static images.
C
What is the “motion silencing illusion”?
a) The perception of sound from movement.
b) When movement prevents us from noticing changes in color, size, or shape.
c) The inability to hear while moving.
d) The illusion that static objects are moving.
B
What is “inattention blindness”?
a) The inability to read.
b) A condition where people only see one color.
c) A problem with visual acuity.
d) Events not being seen because attention is directed elsewhere.
D
What can “attention control problems” like neglect lead to?
a) Enhanced memory.
b) Part of the world being selectively ignored.
c) Improved motor skills.
d) Increased emotional responses.
B
What kind of brain damage is associated with hemi-spatial neglect?
a) Damage to the right temporal/parietal cortex.
b) Damage to the left frontal cortex.
c) Damage to the cerebellum.
d) Damage to the occipital lobe.
A
What is a consequence of hemi-spatial neglect on visual attention?
a) Inability to attend to the right side of space and objects.
b) Enhanced attention to both sides.
c) Inability to attend to the left side of space and objects.
d) No impact on spatial attention.
C
What is “anosognosia”?
a) A heightened awareness of one’s neurological problems.
b) A lack of awareness of neurological problems, such as denying neglect, not recognizing a paralyzed arm, or not realizing one is blind.
c) The ability to perfectly recall past events.
d) The ability to see things that are not there.
B
How does neglect affect imagination?
a) It means individuals would only describe half of the visual world from their imagination.
b) It enhances imaginative capabilities.
c) It has no effect on imagination.
d) It leads to very vivid dreams.
A
For cells responsive to faces, what do most of them code?
a) The emotion displayed on the face.
b) The age of the face.
c) The color of the face.
d) Head view, responding mainly to view (e.g., face, profile).
D
What is the order of importance for coding attention direction in social attention, from most to least important?
a) Body > Face > Gaze.
b) Face > Gaze > Body.
c) Gaze > Face > Body.
d) Body > Gaze > Face.
C
What happens if there is a wrong gaze direction when perceiving a face view?
a) It enhances the correct face view.
b) It inhibits the correct face view.
c) It has no effect on face view perception.
d) It leads to an ambiguous perception.
B
What is a characteristic of autistic individuals regarding gaze processing?
a) They show strong spontaneous attention following.
b) They have little spontaneous attention following but are good at gaze geometry.
c) They are unable to process any gaze information.
d) They have no problems processing gaze.
B
How do chimps use attention direction in competition for food rewards?
a) They don’t claim food rewards if they are in full view of a dominant chimp because it might lead to a fight.
b) They claim food even if a dominant chimp is in view.
c) They share food with dominant chimps.
d) They hide food in plain sight
A
What do scrub jays do if they are seen hiding food?
a) They leave it there.
b) They re-hide it.
c) They eat it immediately.
d) They share it.
B
In social learning, how do monkeys learn to fear objects like snakes?
a) Through direct experience only.
b) Through trial and error.
c) They are innately afraid of snakes.
d) By watching the gaze of other monkeys and learning from it.
D
How do kids learn vocabulary according to the document?
a) From people looking at objects and naming them.
b) By memorizing lists of words.
c) Through reading books independently.
d) By being taught formal grammar rules.
A
When searching for one type of object, what can happen to your perception of other information?
a) You can miss other information.
b) You can process all other information effectively.
c) Your overall attention capacity increases.
d) You become more sensitive to all stimuli.
