This Handbook introduces neurosemiotics, a pluralistic framework to reconsider semiosis as an emergent phenomenon at the interface of biology and culture. Across individual and interpersonal settings, meaning is influenced by external and internal processes bridging phenomenological and biological dimensions. Yet, each of these dyads has been segregated into discipline-specific topics, with attempts to chart their intersections proving preliminary at best. Bringing together perspectives from world-leading experts, this volume seeks to overcome these disciplinary divides between the social and the natural sciences at both the empirical and theoretical levels. Its various chapters chart the foundations of neurosemiotics; characterize linguistic and interpersonal dynamics as shaped by neurocognitive, bodily, situational, and societal factors; and examine other daily neurosemiotic occurrences driven by faces, music, tools, and even visceral signals. This comprehensive volume is a state-of the-art resource for students and researchers interested in how humans and other animals construe experience in such fields as cognitive neuroscience, biosemiotics, philosophy of mind, neuropsychology, neurolinguistics, and evolutionary biology.
