Maternal Child-Directed Speech Toward Children With Infantile Spasm or West Syndrome

Area of Science:

• Developmental Psychology
• Neuroscience
• Linguistics

Background:

• Maternal child-directed speech (MCDS) is crucial for language development.
• Limited understanding of MCDS adaptation in Infantile Spasms (WS), especially with co-occurring intellectual disability (WID) or autism spectrum disorder (WASD).

Purpose of the Study:

• Investigate maternal speech adaptations in WS, WID, and WASD compared to typically developing (TD) children.
• Examine how MCDS features correlate with children's developmental quotients (DQ) across these groups.

Main Methods:

• Analyzed MCDS from 44 mother-child dyads during free play.
• Utilized CHILDES for transcription and analysis of lexical diversity and pragmatic features.
• Focused on features like exclamations, directiveness, questions, attention-directing expressions, and mental state references.

Main Results:

• No significant differences in lexical diversity between groups.
• Mothers of children with WS used more exclamations, attention-directing expressions, and mental state references.
• MCDS features correlated with DQ in WS and TD groups, but not in WID or WASD subgroups.

Conclusions:

• Mothers flexibly adapt MCDS to children's needs, with unique strategies in WS.
• Findings highlight the importance of tailored parent-mediated interventions for complex neurodevelopmental conditions.
• MCDS may serve as an indicator of developmental status and a target for early intervention.
