| Conceptual Peg Hypothesis |

Definition
| 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 |

| Paired Associate Learning |
|
Definition
| a learning task in which participants are first presented with pairs of words, then one word of each pair is presented and the task is to recall the other word |

|
Term
|
Definition
| participants create mental images and then scan them in their minds |
|
|
Term
|
Definition
| a debate about whether imagery is based on spatial mechanisms such as those involved in perception, or is based on mechanisms related to language (called propositional mechanisms) |
|
|
Term
|
Definition
| a representation in which different parts of an image can be described as corresponding to specific locations in space |
|
|
Term
|
Definition
| something that accompanies the real mechanism but is not actually part of the mechanism |

|
Term
| Propositional Representation |
|
Definition
| relationships can be represented by abstract symbols, such as an equation, or a statement such as "The cat is under the table." |

Term
| Depictive Representations |
|
Definition
| representations that are like realistic pictures that resemble an object, so that part of the representation correspond to parts of the object |
|
|
Term
| Tacit Knowledge Explanation |
|
Definition
| an explanation proposed to account for the results of some imagery experiments that states that participants unconsciously use knowledge about the world in making their judgements. This explanation has been used as one of the arguments against describing imagery as a depictive or spatial representation |

Definition
| 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 this mental image ~~ Measure when their visual field "overflows" with the mental image |

Term
| Rule-Based Approach to Mechanical Reasoning |
