| Outline of Final Research Achievements |
I have examined mechanisms of lexical diffusion in phonology, morphology, syntax, semantics, and lexicon in the history of English from a perspective of complex adaptive systems (selection, self-organization, scaling of parameters, robustness and networks of connections, etc.) for the past decades. In the present study I further discussed that lexical diffusion is the fundamental mechanism of language evolution, synthesizing the following perspectives: (1) the impact of the polysemous links of the verbs on the organization of semantic graph which creates a historically robust small-world network, based on the data from Historical Thesaurus of the Oxford English Dictionary (2009), (2) the lexical and syntactic ambiguities from an evolutionary perspective of sequential and combinatorial relationships in the prefrontal brain and the evolution of word order as resolution of these ambiguities, using near-infrared spectroscopy.
