Cognitive Psychology - Visual Imagery Flashcards
a type of mental imagery involving vision, in which an image is experienced in the absence of a visual stimulus
visual imagery
experiencing a sensory impression in the absence of sensory/physical input, is used to include all the senses
mental imagery
the debate about whether thought is possible in the absence of images
imageless thought debate
a learning task in which participants are first presented with pairs of words, then one word in each pair is presented and the task is recall the other word
paired associate learning
to explain that memory for pairs of concrete nouns is better than memory for pairs of abstract nouns, Paivio (1963, 1965) proposed a hypothesis in which concrete nouns create images that other words can “hang onto”
conceptual peg hypothesis
Shepard and Metzler inferred cognitive processes using ______ ______, determining the amount of time needed to carry out various cognitive tasks
mental chronometry
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
imagery debate
Kosslyn proposes that the mechanism responsible for imagery involves _________ representations - representations in which different parts of an image can be described as corresponding to specific locations in space
spatial representations
an argument against spatial representations, proposed by Pylyshyn (1973) who argues that the spatial experience of mental images is something that accompanies the real mechanism but not actually part of the mechanism
epiphenomenon
Pylyshyn proposed that, rather than the spatial representations suggested by Kosslyn, the mechanism underlying imagery involved ___________ representations - representations in which relationships can be represented by abstract symbols, such as an equation, or statement, such as “the cat is under the table”
propositional
a representation that corresponds to spatial representations, where each part of the representation specifies a part of the corresponding object and the distance between the different parts in the representation preserve the corresponding distances between the parts of the object
depictive representation
a task used in imagery experiments in which participants are asked to form a mental image of an object and to imagine that they are walking toward the mental image
mental walk task
neurons in the human brain studied by Kreiman, which fire in the same way when a person sees a picture of an object and when a person creates a visual image of the object
imagery neurons
Each point on a visual stimulus causes activity at a specific location on a brain structure, such as the visual cortex, and points next to each other on the stimulus cause activity at points next to each other on the structure
topographic map
damage to the parietal lobe in which the patient ignores objects in one half of the visual field
unilateral neglect
a method in which things to be remembered are placed at different location in a mental image of a spatial layout - where placing images at locations can help with retrieving memories later
method of loci
a technique involving imagery, whereby each item is associated in imagination with a number–word pair
pegword technique
the ability to image spatial relations, such as the layout of a garden.
Spatial imagery
the ability to image visual details, features, or objects, such as a rose bush with bright red roses in the garden
Object imagery
a test designed to measure spatial imagery.
Participants see 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
paper folding test
a questionnaire designed
to measure object imagery. Participants rate, 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.”
vividness of visual imagery questionnaire
A task in which a line drawing is degraded by omitting parts of the drawing and obscuring it with a visual noise pattern. The person’s task is to identify the object.
Degraded pictures task
a task requiring participants to judge whether pictures were two views of the same object or mirror-image objects.
mental rotation task
representations in which relationships can be represented by abstract symbols such as an equation, or reading the statement such as “the cat is under the table”
propositional representations
spatial representations in which we imagine the picture of the cat under a table, and parts of the representation correspond to parts of the object
depictive representations
Paivio showed that it was easier to remember ____________ nouns, like truck and tree, that can be imagined than it is to remember abstract nouns, like truth and justice, that are difficult to imagine
concrete
Paivio used the paired associate learning technique and found that _________ is better for pairs of concrete nouns
memory
Paivio proposed the conceptual peg hypothesis to explain what finding?
memory is better for concrete nouns
if presenting the pair boat–hat creates an image of a boat, then presenting the word boat later will bring back the boat image, which provides a number of places on which participants can place the hat in their mind - what hypothesis explains this?
conceptual peg
paivio inferred cognitive processes by measuring what?
memory
Shepard and Metzler inferred cognitive processes using what?
mental chronometry
mental chronometry is the study of what?
processing speed
results of Shepard and Metzler’s experiment showed that mental and perceptual images both involve _______ representations of the stimulus
spatial
the idea that there is a spatial correspondence between imagery and perception is supported by Kosslyn, who used a task called ______ _____, in which participants create mental images and then scan them in their mind
mental scanning
an epiphenomenon is a _______ phenomenon that occurs alongside or in parallel to a ________ phenomenon
- secondary
- primary
neurons that fire in the same way when the persons eyes are closed and they imagined a baseball or a face
imagery neurons
________ _______ respond in the same way to perceiving an object and to imagining an object
imagery neurons
Each point on a visual stimulus causes activity at a specific location on a brain structure, such as the visual cortex, and points next to each other on the stimulus cause activity at points next to each other on the structure.
topographic map
leaving a footprint in the wet sand - with a deep indentation for the heel, a rise for the arch and each toe clearly identified- is similar to which concept?
topographic map
imagine a map of your state that includes three locations: the place where you live, a town that is far away, and another town that is closer but does not fall on a straight line connecting your location and the far town.
Starting at your location, to form an image of a black speck moving along a straight line between your location and the closer town.
what is this an example of ?
mental scanning
mental chronometry is the empirical study of what?
reaction time
The basic idea of the propositional representation is that relationships between objects are represented by ______ and not by spatial mental images of the scene
symbols
a bottle under a table would be represented by a formula made of symbols like UNDER(BOTTLE,TABLE) according to _______ representations
propositional
representing a cat under a table by visualising an image of a cat literally under a table in mental space
deptictive
the visual cortex is organised as a topographic map, in which specific locations on a visual ________ cause activity at specific locations in the visual __________, and points next to each other on the stimulus cause activity at locations next to each other on the cortex.
- stimulus
- cortex
in an experiment by Kozhevnikovs, the participants were given two measures of spatial imagery, what were they?
- spatial imagery
- object imagery
