Referential communication skills in children with Down Syndrome

Area of Science:

• Developmental Psychology
• Linguistics
• Genetics

Background:

• Referential communication, the ability to convey information effectively, is crucial for social interaction and language development.
• Children with Down syndrome (DS) often exhibit challenges in pragmatic language, necessitating investigation into their communication skills.
• Understanding the interplay between nonverbal abilities and referential communication is vital for targeted interventions.

Purpose of the Study:

• To investigate referential communication skills in children with Down syndrome (DS).
• To analyze the development of pragmatic language in relation to nonverbal skills in children with DS.
• To assess referential message production and comprehension, including message orientation and adequacy.

Main Methods:

• A study population of 24 children, comprising 12 with DS and 12 typically developing controls (mean age ~7.6 years).
• Phase 1 involved nonverbal skills assessment for all participants.
• Phase 2 specifically evaluated referential communication skills in both production and comprehension.

Main Results:

• A significant relationship was observed between nonverbal skills and referential communication performance, particularly in children with DS.
• Children with DS demonstrated better performance in message production ('talking') compared to message comprehension ('listener').
• Within the listener condition, a notable correlation existed between the adequacy and inadequacy of messages conveyed.

Conclusions:

• Referential communication skills are demonstrably influenced by a combination of verbal and nonverbal factors.
• Nonverbal abilities play a critical role in the referential communication success of children with Down syndrome.
• Further research should explore specific interventions targeting both verbal and nonverbal components to enhance communication in DS.
