Early Language Access: A Lifeline for Deaf Infants

Imagine a world where a child's access to language is delayed for years, and with it, a cascade of developmental challenges begins. This is the stark reality for many deaf and hard-of-hearing children who are denied early exposure to sign language. In their 2018 commentary, Sign Language for Deaf Infants: A Key Intervention for a Developmental Emergency, Dr. Arielle Spellun and her collaborator at Gallaudet University, Dr. Poorna Kushalnagar, emphasize the urgency of introducing sign language early to prevent language deprivation—a developmental emergency with lifelong consequences.

The article highlights the story of a seven-year-old girl with profound congenital hearing loss, whose delayed introduction to sign language led to significant language delays despite receiving cochlear implants at two years old. Her experience is not unique. Deaf children, even in higher income countries, with advanced diagnostic tools and interventions like cochlear implants, often face language deprivation when sign language is not included in their early education.

A Developmental Crisis with Long-Term Impact

In the United States, early diagnosis of hearing loss has improved significantly, but early language interventions still lag. Without accessible language—such as natural sign language—D/HH children risk linguistic and cognitive deprivation. This can lead to poor educational outcomes, delayed cognitive development, and even social isolation.

As the authors point out, simply relying on auditory devices like cochlear implants without including sign language can leave children without the linguistic foundation they need for learning. The key is in combining auditory interventions with sign language, providing a bilingual approach that maximizes a child's developmental potential.

Why Early Sign Language Matters

Research consistently shows that early language exposure, whether signed or spoken, is crucial for cognitive and educational development. Introducing sign language from birth not only provides immediate communication tools but also promotes brain development in areas related to language and cognition. Sign language is not a fallback—it's a primary language that deaf children can acquire naturally and easily, ensuring they don't fall behind during the critical early years.

Pediatricians, educators, and policymakers must promote sign language as an essential part of any intervention plan for D/HH children. This means guiding parents to embrace sign language from the very beginning and ensuring that medical professionals are well-versed in the importance of early accessible language.

The Takeaway

The message from Spellun and Kushalnagar is clear: deaf children deserve access to language from day one, and sign language is the lifeline that can prevent a developmental crisis. By prioritizing early sign language education, we can give deaf infants the best possible start in life, allowing them to thrive academically, socially, and emotionally.
