An embodied multi-articulatory multimodal language framework: A commentary on Karadöller, Sümer and Özyürek

Area of Science:

• Linguistics
• Cognitive Science
• Developmental Psychology

Background:

• Traditional language acquisition research often distinguishes language and gesture using modality, a method unsuitable for sign language.
• Existing theories may overlook the integrated nature of gesture and language in sign languages.

Purpose of the Study:

• To propose that co-sign gestures should be analyzed in parallel with co-speech gestures within language acquisition frameworks.
• To advocate for a unified, multimodal perspective on language acquisition that encompasses both signed and spoken modalities.
• To highlight the necessity of an embodied, multi-articulatory framework for comprehensive language acquisition theories.

Main Methods:

• Comparative analysis of gesture functions in spoken and signed communication.
• Theoretical argumentation for integrating co-sign and co-speech gesture research.
• Conceptual development of an embodied multi-articulatory multimodal framework.

Main Results:

• Demonstrates the inadequacy of modality-based distinctions for sign language research.
• Establishes the functional equivalence of co-sign and co-speech gestures in embodied communication.
• Identifies the need for a theoretical shift towards multimodal language acquisition.

Conclusions:

• Co-sign gestures play a crucial role and must be integrated into theories of language acquisition.
• A truly multimodal approach is necessary for a complete understanding of how language is acquired.
• An embodied multi-articulatory multimodal framework offers a robust foundation for broader claims in language acquisition research.
