Term
Abstraction Theory
Definition
Holds that we abstract general properties from the instances we have studied.  
Term
Amodal Hypothesis
Definition

There is an immediate abstract system, perhaps the propositional representation, and that we have systems for converting back and forth between the perceptual and motor representations and this is abstract representation.

Term
Amodal Symbol System
Definition
Neural representations from vision are transduced in an amodal representation such as a frame, semantic network or feature list. These amodal representations are used during word understanding. 
Term
Arguments
Definition

Typically refer to particular times, places, people, or objects, and typically correspond to the nouns.

Term
Default Values
Definition

Values we take for granted versus values we must include that do not apply to all items as is all birds fly, except the ostrich.

Term
Dual-Code Theory
Definition

 Rather than abstract propositional representations, we represent information in combined verbal and visual codes.

Term
Embodied Cognition
Definition

The contribution of the environment and our bodies in shaping our cognition.

Thelen (2000)

Embodied means that it arises from bodily interactions with the world and is continually meshed with them”.

·         Cognition depends on the kinds of experiences that come from having a body with particular perceptual and motor capabilities that are inseparably linked together.

Term
Exemplar Theory
Definition

Holds that we store no central concept, but only specific instances.

Term
Isa Link
Definition

Links nodes for the properties of categories that associate them.

Term
Link
Definition

Representational arrows connecting nodes in a propositional network.

 

Term
Mirror Neuron
Definition

A neuron that fires both when an animal acts and when the animal observes the same action performed by another.

Term
Mnemonic Technique
Definition
This is a memory boosting technique that applies meaning to information
Term
Multimodal Hypothesis
Definition

We have various representations tied to different perceptual and motor systems and that we have means of directly converting one representation to another.

·         The person has converted info from the modality of the presentation to some other modality.

Term
Node
Definition

The propositions, relations, and arguments in a propositional network.

Term
Perceptual Symbol System
Definition

Suggests that all information is represented in terms that are specific to a particular perceptual modality (viusual, auditory, etc.) and basically perceptual.

Term
Propositional Network
Definition

Propositions represented in network form.

·         Visually represented by the ellipsis.  

Term
Propositional Representation
Definition

Mental relationships between objects are represented by symbols and not by mental images of the scene.

Term
Relations
Definition

Organizes the arguments and typically corresponds to the verbs and other relational terms.

Term
Schema
Definition

Describes a pattern of thought or behavior that organizes categories of information and the relationships among them.

·         They are abstractions from specific instances that can be used to make inferences about instances of concepts they represent.

·         It is a way of encoding default assumptions.  

Term
Script
Definition

Event schemas are focused on patterns of behavior that should be followed for certain events.

·         Stereotypic sequences of actions.

Term
Slot
Definition

Slots specify values of various attributes that members of a category possess.
