Simulating Frontotemporal Pathways Involved in Lexical Ambiguity Resolution

Lexical ambiguity resolution is the process whereby one meaning of an ambiguous lexical item is activated over an alternative meaning. This paper introduces a preliminary model of lexical ambiguity resolution based on known cortical regions that are activated in this process, including areas of the prefrontal and temporal lobes. Through the interaction of these regions, the model is able to simulate findings associated with the time-course of meaning activation in context for ambiguous words whose alternative meanings differ in frequency.
