Computational challenges of evolving the language-ready brain

A theory of evolving the language-ready brain requires a theory of what it is that evolved. We offer the TCG (Template Construction Grammar) model of comprehension and production of utterances to exhibit hypotheses on how utterances may link to “what language is about.” A key subsystem of TCG is the SemRep system for semantic representation of a visual scene. We offer an account of how it may have evolved as an expansion of the ventral pathway...
