Language Environments and Spoken Language Development of Children With Hearing Loss

Area of Science:

• Child language development
• Speech-language pathology
• Early childhood education

Background:

• Understanding the link between adult language input and child language output is crucial for early intervention.
• Previous research highlights the importance of rich language environments for cognitive and linguistic growth.

Purpose of the Study:

• To investigate the relationship between the quantity and diversity of adult language input and the language production of preschool children with hearing loss.
• To compare language input from teachers and parents in different environments.

Main Methods:

• Utilized Language Environment Analysis (LENA) technology to audio-record language environments of 26 preschool children with hearing loss over two days.
• Analyzed language samples for quantity (adult word count, child vocalization count, conversational turns) and diversity (lexical, syntactical, clausal complexity).

Main Results:

• A significant relationship was found between the quantity of adult language input and child language production.
• No significant relationship was observed between the diversity of adult language input and child language production.
• Teachers and parents differed significantly in the diversity of their language input.

Conclusions:

• The quantity of adult language input is a key factor influencing child language production in preschool children with hearing loss.
• Significant differences in language input diversity between home and school environments warrant further investigation for tailored interventions.
