The study of gesture in cognitive linguistics: How it could inform and inspire other research in cognitive science

Cognitive linguists are increasingly extending their paradigm to include the study of gestures. The bottom-up, usage-based approach in cognitive linguistics has advanced the methods for identifying gesture functions, starting from a detailed analysis of gesture forms. Theoretical notions from cognitive linguistics also help explain the means by which the forms of gestures can be interpreted as meaningful functions. Principles of conceptual metonymy explain how gestures indicate referents through the partial representation of their features that are relevant in the context of use. Conceptual metaphor theory sheds light on how abstract notions can be represented in gesture via comparison with physical source domains. Furthermore, every gestural representation inherently requires the gesturing speaker to employ a specific viewpoint for their depiction-something which is normally not expressed verbally. These aspects of gesture provide insights into processes of thinking for speaking that can be exploited in various fields of cognitive science research. Referential gestures also normally combine pragmatic and interactive functions (showing stance-taking, for example) with representational or deictic functions. The multiple functions of gesture combined with those of speech raise questions for further research about how viewing-listeners interpret and combine information from the multiple semiotic systems employed by gesturing-speakers. Finally, gesture use has been shown to correlate not only with lexical concepts but also in some ways with grammatical constructions. This gives rise to fundamental questions about what constitutes the grammar of a language. Gesture analysis thus raises issues for consideration in any research in cognitive science that concerns spoken language.
