Bilingual aphasia: Explanations in population encoding

Publication date: February 2019Source: Journal of Neurolinguistics, Volume 49Author(s): Stephen E. NadeauAbstractThe study of bilingual aphasia has particular power to determine the neural basis of language function and can advance the treatment of aphasia. No theory of bilingual language has provided a coherent and comprehensive account for research results. I begin with a précis of a population encoding model of language function that assumes that representations are based upon the patterns of activity of large populations of neurons. I then consider how regularities in specific domains of language function (e.g. in semantics and phonologic sequence knowledge), frequency effects, and age of acquisition effects (strongest in lexical-semantics) might account for observed behavior in polyg...
