Syntactic encoding in written language production by deaf writers: A structural priming study and a comparison with...

Area of Science:

• Psycholinguistics
• Cognitive Science
• Writing Systems

Background:

• Understanding language production in deaf individuals is crucial for inclusive communication.
• Written language production involves complex syntactic and lexical processes.
• Previous research has not fully explored differences in written language production between deaf and hearing individuals.

Purpose of the Study:

• To investigate potential differences in syntactic encoding and lexical representations between deaf and hearing writers.
• To examine the role of phonological versus orthographic identity in priming effects for deaf and hearing writers.
• To determine if deaf writers utilize distinct representational systems in written language production.

Main Methods:

• Three structural priming experiments were conducted with deaf and hearing writers of Mandarin Chinese.
• Participants completed tasks involving written sentence production with varying prime-target relationships (lexical, homophonic, orthographic).
• Priming effects and lexical boosts were measured to infer underlying cognitive processes.

Main Results:

• Deaf and hearing writers exhibited comparable structural priming and lexical boosts, indicating similar sensitivity to syntactic experience.
• Hearing writers showed homophone priming for both homographic and heterographic homophones, while deaf writers only showed it for homographic homophones.
• Neither group showed priming based on orthographic identity across different Chinese scripts (Simplified vs. Traditional).

Conclusions:

• Syntactic encoding in writing utilizes shared syntactic and lexical representations in both deaf and hearing writers.
• Lexical representations in deaf writers are influenced more by orthographic than phonological identity.
• These findings highlight the adaptability of language processing systems based on sensory experience.
