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.
Different diseases and disorders can affect the biological workings of semantic memory. A variety of studies have been done in an attempt to determine the effects on varying aspects of semantic memory. For example, Lambon, Lowe, & Rogers studied the different effects semantic dementia and herpes simplex virus encephalitis have on semantic ...
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:
Spreading activation is a method for searching associative networks, biological and artificial neural networks, or semantic networks. [1] The search process is initiated by labeling a set of source nodes (e.g. concepts in a semantic network) with weights or "activation" and then iteratively propagating or "spreading" that activation out to other nodes linked to the source nodes.
Biolinguistics can be defined as the study of biology and the evolution of language. It is highly interdisciplinary as it is related to various fields such as biology, linguistics, psychology, anthropology, mathematics, and neurolinguistics to explain the formation of language. It seeks to yield a framework by which we can understand the ...
Semantic processing is the deepest level of processing and it requires the listener to think about the meaning of the cue. Studies on brain imaging have shown that, when semantic processing occurs, there is increased brain activity in the left prefrontal regions of the brain that does not occur during different kinds of processing. One study ...
One example of a theory from cognitive science that has made its way into the cognitive semantic mainstream is the theory of prototypes, which cognitive semanticists generally argue is the cause of polysemy. [citation needed] Cognitive semanticists argue that truth-conditional semantics is unduly limited in its account of full sentence meaning ...
Cognitive semiotics is the study model of meaning-making, applying methods and theories from semiotics, linguistics, psychology, cognitive science, computational modeling, anthropology, philosophy and other sciences. Contrary to classical cognitive science, cognitive semiotics is explicitly involved with questions of meaning, having recourse ...
