A mental representation (or cognitive representation), in philosophy of mind, cognitive psychology, neuroscience, and cognitive science, is a hypothetical internal cognitive symbol that represents external reality or its abstractions. [1] [2] Mental representation is the mental imagery of things that are not actually present to the senses. [3]
Prototype theory is a theory of categorization in cognitive science, particularly in psychology and cognitive linguistics, in which there is a graded degree of belonging to a conceptual category, and some members are more central than others.
The mental space is a theoretical construct proposed by Gilles Fauconnier [1] corresponding to possible worlds in truth-conditional semantics.The main difference between a mental space and a possible world is that a mental space does not contain a faithful representation of reality, but an idealized cognitive model. [2]
One naturalistic account of the representation relationship is the teleofunctionalist semantics of Fred Dretske. In his book Explaining Behavior, Dretske outlines a theory for how a component of a physical system can come to possess semantic content. This theory characterizes a relationship as representational when: one entity is a natural sign ...
The classical model of symbolism is characterized by (1) a combinatorial syntax and semantics of mental representations and (2) mental operations as structure-sensitive processes, based on the fundamental principle of syntactic and semantic constituent structure of mental representations as used in Fodor's "Language of Thought (LOT)".
Exemplar Theory is often contrasted with prototype theory, which proposes another method of categorization.Recently the adoption of both prototypes and exemplars based representations and categorization has been implemented in a cognitively inspired artificial system called DUAL PECCS (Dual Prototypes and Exemplars based Conceptual Categorization System) that, due to this integration, has ...
A semantic hub represents a focal point in the brain where all semantic information pertaining to a specific word is integrated. For example, the color, shape, size, smell, and sound associated with the word “cat” would be integrated at the same semantic hub. Some candidate regions for semantic hubs include:
Semantics within psychology is the study of how meaning is stored in the mind. Semantic memory is a type of long-term declarative memory that refers to facts or ideas which are not immediately drawn from personal experience. It was first theorized in 1972 by W. Donaldson and Endel Tulving.
