Week 8 - Visual Imagery

Question 1

Mental imagery

Answer 1

A broader (than ‘visual imagery’) term that refers to the ability to re-create the sensory world in the absence of physical stimuli, is used to include all of the senses.

Question 2

visual imagery

Answer 2

seeing in the absence of a visual stimulus

Question 3

imageless thought debate

Answer 3

with some psychologists taking up Aristotle’s idea that “thought is impossible without an image” and others contending that thinking can occur without images.

Question 4

conceptual peg hypothesis

Answer 4

According to this hypothesis, concrete nouns create images that other words can “hang onto.”

Question 5

mental chronometry

Answer 5

determining the amount of time needed to carry out various cognitive tasks.

Question 6

mental scanning

Answer 6

where participants create mental images and then scan them in their minds

Question 7

imagery debate

Answer 7

a debate about whether imagery is based on spatial mechanisms, such as those involved in perception, or on mechanisms related to language, called propositional mechanisms.

Question 8

spatial representations

Answer 8

representations in which different parts of an image can be described as corresponding to specific locations in space

Question 9

Epiphenomenon

Answer 9

Something that accompanies the real mechanism but is not actually part of the mechanism

Question 10

Propositional representations

Answer 10

Representations in which relationships can be represented by abstract symbols, such as an equation, or a statement, such as “The cat is under the table.”

Question 11

depictive representations.

Answer 11

Spatial representations such as the picture of the cat under the table in which parts of the representation correspond to parts of the object

Question 12

mental walk task

Answer 12

task in which they were to imagine that they were walking toward their mental image of an animal

Question 13

“overflow”

Answer 13

when the image filled the visual field or when its edges started becoming fuzzy.

Question 14

imagery neurons

Answer 14

Neurons that respond to some images and not others. Also fire when image is imagined.

Question 15

Explain the way the visual cortex is organized as a topographic map,

Answer 15

specific locations on a visual stimulus cause activity at specific locations in the visual cortex, and points next to each other on the stimulus cause activity at locations next to each other on the cortex.

Question 16

uni-lateral neglect

Answer 16

in which the patient ignores objects in one half of the visual field, even to the extent of shaving just one side of his face or eating only the food on one side of her plate.

Caused by damage to the parietal lobe

Question 17

the method of loci

Answer 17

a method in which things to be remembered are placed at different locations in a mental image of a spatial layout.

Question 18

pegword technique

Answer 18

involves imagery, as in the method of loci, but instead of visualizing items in different locations, you associate them with concrete words.

Question 19

Spatial imagery (df)

Answer 19

refers to the ability to image spatial relations, such as the layout of a garden.

Question 20

Object imagery (df)

Answer 20

refers to the ability to image visual details, features, or objects, such as a rose bush with bright red roses in the garden

Question 21

paper folding test (PFT) - (purpose / process: 2 steps)

Answer 21

is designed to measure spatial imagery.

Participants saw a piece of paper being folded and then pierced by a pencil . Their task was to pick from five choices what the paper would look like when unfolded

Question 22

vividness of visual imagery questionnaire (VVIQ) - (purpose / process: 2 steps)

Answer 22

was designed to measure object imagery.

Participants view, and then rated, on a 5-point scale, the vividness of mental images they were asked to create.

A typical item: “The sun is rising above the horizon into a hazy sky.”
