Dual-code theory

Embodied cognition
The viewpoint that the mind can only be understood by taking into account the human body and how it interacts with the environment.
Exemplar theories
Theories holding that concepts are represented by specific instances in our experience and that new instances are categorized on the basis of their similarity to the stored representations.

Mirror neurons
Neurons that fire both when an animal is performing an action and when the animal observes another animal performing an action.

A system for representing information in which the terms are tied to particular perceptual modalities.
Proposition

Propositional representation
A representation of meaning as a set of propositions.
Prototype theories
Models proposing that we store a single prototype of a category member and classify specific objects or events in terms of their similarity to the prototype.
