The Science of Language Learning with Owen Hawthorne

Welcome to "The Science of Language Learning," the podcast where we break down the fascinating process of learning a new language as an adult! Whether you're just starting out or already on your language journey, our hosts dive into the science behind how we learn, retain, and use new languages— all while keeping the conversation casual, fun, and easy to understand. We’ll cover everything from brain hacks for faster learning to real-world tips on staying motivated. So grab your headphones, get comfortable, and let’s explore the art and science of mastering a new language together! The content of this podcast is based off the research of Dr. Bo Bennett, a social psychologist specializing in critical thinking, human behavior, and cognitive skills.

Bimodal Bilingualism and Linguistic Diversity: What Adult Language Learners Should Know

When we talk about bilingualism, many of us immediately think of someone who speaks two spoken languages — for example, English and Spanish, French and German, or Mandarin and Cantonese. But did you know that bilingualism can also involve two different “modes” of language? This phenomenon, called bimodal bilingualism, is a fascinating aspect of linguistic diversity that is reshaping our understanding of language acquisition and language learning.

As an adult language learner, expanding your knowledge about different forms of bilingualism not only broadens your cultural horizons but also enriches your approach to learning a new language. In this post, we’ll explore what bimodal bilingualism is, the role it plays in linguistic diversity, and how understanding it can benefit your own language learning journey.

What is Bimodal Bilingualism?

Bimodal bilingualism refers to the ability to use two languages that operate in different modalities: a spoken language and a signed language. Unlike traditional bilingualism, where both languages are spoken or both are written, bimodal bilinguals communicate using both speech and sign.

For example, a person might speak English fluently and also use American Sign Language (ASL). This bilingual individual effortlessly switches between vocalizing words and signing, sometimes even blending the two simultaneously. This is different from code-switching in spoken languages because it involves different sensory channels — auditory-oral vs. visual-gestural.

The Unique Features of Bimodal Bilingualism

Simultaneous use: Bimodal bilinguals can produce signs and speak at the same time, creating a phenomenon called "code-blending."
Distinct brain activation: Scientific studies show that different areas of the brain activate when processing signed versus spoken languages, meaning bimodal bilingualism provides a unique cognitive experience.
Linguistic flexibility: Because they juggle two entirely different modalities, bimodal bilinguals develop enhanced abilities in multitasking and language switching.

Linguistic Diversity and Why It Matters

Linguistic diversity is more than just the existence of many different languages. It also includes diverse ways languages are used and embodied — including the use of signed languages. Signed languages have their own grammar, vocabularies, and cultural significance. Recognizing bimodal bilingualism highlights the richness of human communication and reminds us that language learning can take many forms.

Celebrating linguistic diversity means appreciating that communication is not limited to spoken words alone. This knowledge encourages inclusivity and respect for deaf communities and other users of signed languages worldwide.

What Adult Language Learners Can Take Away From Bimodal Bilingualism

Understanding bimodal bilingualism has several practical implications for adult language learners interested in the science of language learning:

Appreciate Multiple Modalities: Language is not just auditory and oral; it can be visual and gestural. This broad viewpoint may inspire some learners to explore signed languages as part of their language journey.
Enhanced Cognitive Benefits: Research shows that bilingualism improves executive function, working memory, and problem-solving skills. Bimodal bilingualism might offer even more cognitive flexibility because it engages different sensory modalities simultaneously.
New Language Learning Strategies: Learning a signed language alongside a spoken one can deepen your understanding of language structure and communication dynamics. This can inform how you approach learning any new language, spoken or signed.
Greater Cultural Awareness: Learning about bimodal bilingualism encourages empathy and cultural competence, crucial traits in global communication and language acquisition.

Science Behind Language Learning and Practice Tools

Whether you’re fascinated by bimodal bilingualism or simply want to improve your adult language learning skills, the process of how to learn a language effectively is complex but manageable with the right tools. Language acquisition involves a combination of exposure, repetition, and practice, and the science of language learning offers evidence-based methods to make it easier.

One highly recommended resource is ScienceBasedLearning.com. They provide a simple ebook, audiobook, and video language learning system, combined with an online practice app that uses the science behind spaced repetition to maximize your learning and retention. This system is especially effective for adult language learners who might struggle with consistency and memory recall.

Integrating a multisensory approach to studying, inspired by concepts like bimodal bilingualism, can make your language learning journey more dynamic and enjoyable.

Final Thoughts

Bimodal bilingualism opens a window into the incredible diversity of human communication. For adult language learners, understanding this form of bilingualism expands perspectives on what language is and how it can be learned and used. Whether you stick with spoken languages or explore signed ones as well, embracing linguistic diversity enriches your own language learning experience and builds a deeper appreciation for the science of language learning.
