Sign Language Science and Natural Acquisition

How does the human brain process and acquire language when it is expressed through space and movement rather than sound? Understanding the science behind sign language acquisition is essential for educators, advocates, and language enthusiasts who want to support natural learning environments. In this text-based course, you will explore the linguistic foundations of sign languages and the biological and environmental factors that influence natural learning. You will gain a deep understanding of how early exposure impacts cognitive development, and how to apply these insights to support successful language development. What you'll learn: Understand the foundational linguistic structure of sign languages, including phonology, morphology, and syntax in three-dimensional space; Analyze the critical period hypothesis and how early visual language exposure shapes brain development; Identify the key social, environmental, and cognitive factors that facilitate natural sign language acquisition; Compare the pathways of natural acquisition in deaf children of signing parents versus late-stage learners; Examine modern research on sign language bilingualism and its cognitive benefits; Apply scientific insights to design supportive, accessible environments for sign language learners. The course begins with key terminology and foundational definitions of sign language linguistics before guiding you through cognitive development, environmental influences, and practical applications. You will read research-backed explanations and complete written exercises to solidify your understanding of natural language acquisition. This course is designed for absolute beginners, including parents, educators, students, and anyone curious about cognitive science and linguistics, with no prior background in sign language required.
