The second deficit may be located at the level of the output lexicon. This is because patients are able to recognize the semantic meaning of irregular words even if they pronounce them incorrectly in spoken word. This suggests the visual word form system and semantics are relatively preserved. The third deficit is likely related to semantic ...
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 ...
In his example, the string "John hit the chair" can have "John" deduced as the subject by a child, as a "chair" is unlikely to "hit" (rare (extraneous) examples include "I was hit by a car"). After several of these strings with the verb "hit," the child observes that inanimate objects, unlikely to possess the ability to "hit," consistently ...
The latter, semantic network theory, proposes the idea of spreading activation, which is a hypothetical mental process that takes place when one of the nodes in the semantic network is activated, and proposes three ways this is done: priming effects, neighborhood effects, and frequency effects, which have all been studied in depth over the years.
These elements have been called semantic primitives or semantic markers/features. Each primitive may in turn form part of a propositional statement, which in turn could be represented by an abstract figure e.g. ‘P’. The primitives themselves play a crucial role in categorizing and classifying objects and concepts. [citation needed]
In psychology and cognitive neuroscience, pattern recognition is a cognitive process that matches information from a stimulus with information retrieved from memory. [1]Pattern recognition occurs when information from the environment is received and entered into short-term memory, causing automatic activation of a specific content of long-term memory.
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 ...
{{Semantic markup templates | state = expanded}} will show the template expanded, i.e. fully visible. {{ Semantic markup templates | state = autocollapse }} will show the template autocollapsed, i.e. if there is another collapsible item on the page (a navbox, sidebar , or table with the collapsible attribute ), it is hidden apart from its title ...
