Visual Imagery - Ch. 10 Flashcards
Visual Imagery
Seeing in the absence of a visual stimulus.
Mental Imagery
The ability to re-create the sensory world in the absence of physical stimuli.
Imageless Thought Debate
Thought is impossible without an image vs thinking can occur without images.
Paired Associate Learning
Pairs of words; presented with first word; recall word that was paired during study period;
Conceptual Peg Hypothesis
Concrete nouns create images that other words can “hang onto.”
Mental Chronometry
Determining the amount of time needed to carry out various cognitive tasks.
Mental Scanning
Participants create mental images, then scan them in their minds.
Imagery Debate
Whether imagery is based on spatial mechanisms (perception) or mechanisms related to language (propositional mechanisms).
Spatial Representations
Representations in which different parts of an image can be described as corresponding to specific locations in space.
Epiphenomenon
Something that accompanies the real mechanism, but is not actually part of the mechanism.
Propositional Representations
Representations in which relationships can be represented by abstract symbols, such as an equation or statement.
Depictive Representations
Spatial representations in which parts of the representation correspond to parts of the object.
Mental Walk Task
Imagine they are walking towards their mental image of an animal. Estimate how far they were from animal when they began to experience an overflow (when image filled visual field/edges became fuzzy).
Imagery Neurons
Neurons that fire when imagining images - fire when looking at same image.
Unilateral Neglect
Patient ignores objects in one half of visual field; damage to parietal lobes.
Method of Loci
Method in which things to be remembered are placed at different locations in a mental image of a spatial layout.
Pegword Technique
Associate different items with concrete words.
Spatial Imagery
Ability to image spatial relations.
Object Imagery
Ability to image visual details, features, or objects.
Paper Folding Test (PFT)
Measures spatial memory; piece of paper being folded and pierced by a pencil; pick from five choices what the paper would look like when unfolded.
Vividness of Visual Imagery Questionnaire (VVIQ)
Measures object imagery; rate on 5-point scale the vividness of mental images asked to create.
Degraded Picture Tasks
Determining what a number of degraded line drawings is.
Mental Rotation Task
Judge whether pictures were two views of the same object or mirror-image objects.
Imagery Potential
Ease with which a concept can be imaged.
