Phonological awareness for american sign language

Area of Science:

• Linguistics
• Developmental Psychology
• Deaf Education

Background:

• Phonological awareness (PA) is crucial for reading development in spoken languages.
• The role of PA in sign language processing, specifically American Sign Language (ASL), is less understood.
• Metalinguistic skills are essential for language processing and literacy.

Purpose of the Study:

• To investigate phonological awareness (PA) in American Sign Language (ASL).
• To examine the impact of early ASL exposure on PA skills.
• To explore the relationship between ASL PA and English PA in deaf signers.

Main Methods:

• Development and application of a novel test for ASL phonological awareness.
• Comparison of PA performance between early-exposed and late-exposed ASL signers.
• Correlation analysis between ASL PA and English PA in native signers.

Main Results:

• Deaf signers with early ASL exposure demonstrated superior performance on the ASL PA test compared to later-exposed signers.
• This advantage persisted even when controlling for years of sign language experience.
• A positive correlation was found between ASL PA and English PA in native signers.

Conclusions:

• Early acquisition of ASL is critical for developing robust phonological awareness.
• ASL PA skills may support the development of literacy and reading skills in deaf children.
• Findings highlight the importance of early language access for cognitive development in deaf individuals.
