Modulation of Non-verbal Cues in Bilingual Code-switching

Abstract

In bilingual settings, speakers frequently code switches and gestures facilitates this interaction by bridging linguistic gaps and enhancing clarity and comprehension.  This study aims to explore the relationship between dominant language and gesture usage during code-switching among bilingual speakers with a focus on emblems (speech independent gestures) and illustrators (speech dependent gestures). Although there is extensive literature on bilingualism communication and gesture types in isolation, the relationship between gestures and dominant language use during code-switching remains underexplored. Preliminary studies indicate a relationship between dominant language and gestures (King et. Al,2003; Woolfson, 1991), this study not only highlights the intricate interplay between bilingual language dominance and gesture types but also provides valuable insights into how gesture facilitate comprehension and clarity during bilingual communication. Guided by a mixed-method research paradigm, this study employs descriptive and correlational research design. Data is collected through video recordings of ten bilingual participants, selected through purposive sampling. The analysis is done through Lausberg and Sloetjes (2009) coding system for NEUROGES ELAN, an annotation tool to analyze gesture behavior. Adapting this coding scheme involves customized inclusion of emblems, illustrators gesture type, and frequency analysis. By elucidating this relationship, the findings contribute to a growing understanding of bilingual communication dynamics and offer a framework for future exploration. The findings aim to inform the practitioners, researchers, and educators, encouraging the integration of gesture analysis into studies of bilingualism and code-switching to enhance the scope of the area.
