Sociobiological bases of information structure

The book tackles the sociobiological bases of Information Structure (IS) inquiring both its evidential and neurobiological underpinnings in human communication. Its purpose is to delve into the epistemic and neurocognitive rationales behind the realization of informational hierarchies in a sentence. It zooms in on an interplay, that between IS and evidentiality, that has never been explored in IS studies and seeks to recast IS phenomena in an epistemological perspective. The neurocognitive approaches discussed propose neurophysiological investigations on IS processing, both with ERP and ERS vs. ERD measurements. The book adds some further contribution to ongoing psycholinguistic and neurolinguistic experimental research on the processing of topic-focus and presupposition-assertion dichotomies.
