According to the principle presented, what is imagery considered to be?
A special form of
mental representation
View source
According to the principle presented, who uses imagery more, children or adults?
Children
View source
According to the lecture, what is mental imagery?
A form of
representation
View source
Mental imagery is based on information drawn from what?
Memory
View source
Where does the information used in mental imagery come from?
Memory
as opposed to raw sensory inputs
View source
What are two functions of imagery mentioned in the lecture?
Predict future
events
,
cognitive
tasks
View source
What cognitive tasks can imagery be helpful for?
Insight
Attentional search
Guiding
deliberate
actions
Short-term
storage
Long-term memory retrieval
View source
What does visual perception capture, according to the lecture?
Spatial structure
of an
object
View source
What does imagery create to make explicit properties of objects?
Representation
View source
According to the lecture, when does confusion between imagery and perception occur?
In the case of
hallucinations
View source
Why don’t we usually confuse images with perceptions?
We are
aware
we
constructed
images
View source
How does the level of detail compare between images and visual perceptions?
Images
are
usually
less
detailed
View source
According to perceptual anticipation theory, what kind of representations are visual images?
Depictive representations
View source
According to Pearson & Kosslyn, what do the distances among the parts in the representation correspond to?
Actual distances
among
the
parts
View source
According to perceptual anticipation theory, what brain areas are involved in visual images?
Same as early visual processing
View source
What theory argues that visual perception and visual imagery depend on the same visual buffer?
Kossyln’s perceptual anticipation theory
View source
According to Kossyln’s perceptual anticipation theory, what two predictions follow?
Facilitation and interference
View source
Who conducted an experiment showing evidence for facilitation between imagery and perception?
Pearson, Clifford & Tong (2008)
View source
In the Pearson, Clifford & Tong experiment, what was presented to each eye of the participants?
Green
or
red
horizontal grating
View source
What was more likely to be perceived under binocular rivalry conditions?
Stimulus originally perceived/imagined
View source
What did the findings of Pearson, Clifford, & Tong imply about visual imagery?
Relies on similar processes to perception
View source
Who conducted a dual task experiment that showed interference between visual imagery tasks?
Baddeley & Andrade, 2000
View source
What was the primary task in the Baddeley & Andrade experiment?
Rating vividness of images
View source
What secondary task reduced the vividness of visual imagery in the Baddeley & Andrade study?
Spatial tapping
View source
What secondary task reduced the vividness of auditory imagery more than visual imagery?
Counting task
View source
Who proposed the dual coding hypothesis?
Pavio (1991)
View source
According to Pavio's dual coding hypothesis, what are the two codes for?
Visual, verbal representation
View source
According to Pavio's dual coding hypothesis, what kind of words are recalled better?
Concrete, imageable words
View source
Who studied mental rotation?
Shepard & Metzler, 1971
View source
What was the relationship between decision time and degree of rotation in the Shepard & Metzler study?
Linearly related
View source
Which brain areas are activated by both viewing and imaging an object?
Early visual cortex
View source
Which areas of the brain are activated by both viewing and imaging an object?
BA17 and BA18
View source
Imagery is associated with greater activation of which area of the cortex?
Posterior left cortex
View source
In brain connectivity studies, which brain areas are associated with bottom-up processing?
Early visual cortex, fusiform gyrus
View source
In brain connectivity studies, which brain areas are associated with top-down processing?
Intraparietal sulcus, inferior frontal gyrus
View source
What neuropsychological case showed a dissociation between visual perception and imagery?
The case of C.K.
View source
What deficits did C.K. show?
Severe deficits in object recognition
View source
What ability did C.K. retain?
To draw from
memory
View source
What object discrimination difficulties did C.K. have?
Unable to discriminate overlapping
figures
View source
In what ways was C.K. able to use visual shapes?
Imagine
,
manipulate
, and
alter
them
