Flashcards in Chapter 10 Deck (19):

conceptual peg hypothesis

a hypothesis, associated with Paivio's dual coding theory, that states that concrete nouns create images that other words can hang onto, which enhances memory for these words


depictive representation

corresponds to spatial representation. So called because a spacial representation can be depicted by a picture



phenomenon that accompanies a mechanism but is not actually part of the mechanism. An example of epiphenomenon is lights that flash on a mainframe computer as it operates


food craving

intense desire to eat a specific food


imageless thought debate

the debate about whether thought is possible in the absence of images


imagery debate

debate whether imagery is based on spatial mechanisms, such as those involved in perception, or on propositional mechanisms that are related to language


imagery neuron

type of category-specific neuron that is activated by imagery


mental chronometry

determining the amount of time needed to carry out a cognitive task


mental imagery

experiencing a sensory impression in the absence of sensory input


mental scanning

process of mental imagery in which a person scans a mental image in his or her mind


mental walk task

task used in imagery experiments in which participants are asked to form a mental image of an object and to imagine a spatial layout.


method of loci

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


paired-associate learning

learning task in which participants are first presented with pairs of words, the one word of each pair is presented and the task is to recall the other word


pegword technique

method of remembering things in which the things to be remembered are associated with concrete words


propositional representation

representation in which relationships are represented by symbols, as when the words of a language represent objects and the relationships between objects


spatial representation

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


tacit knowledge explanation

an explanation proposed to account for the results f some imagery experiments that states that participants unconsciously use knowledge about the world in making their judgments. This explanation has been used as one of the arguments against describing mental imagery as a depictive or spatial representation


unilateral neglect

a problem caused by brain damage, usually to the right parietal lobe, in which the patient ignores objects in the left half of his or her visual field


visual imagery

type of mental imagery involving vision, in which an image is experienced in the absence of a visual stimulus
