Pragmatics and SLI: within-group variations in discourse behaviors

Area of Science:

• Child language development
• Speech-language pathology
• Linguistic pragmatics

Background:

• Specific Language Impairment (SLI) affects children's language acquisition.
• Understanding discourse behaviors in SLI is crucial for targeted interventions.
• Distinguishing between expressive-only (E:SLI) and combined expressive-receptive (E-R:SLI) deficits is important.

Purpose of the Study:

• To compare discourse behaviors between children with E:SLI and E-R:SLI.
• To contrast SLI subgroups with typically developing peers matched for age and Mean Length of Utterance (MLU).
• To identify specific pragmatic differences related to receptive language skills in SLI.

Main Methods:

• Comparative analysis of discourse behaviors.
• Inclusion of children with E:SLI, E-R:SLI, and typically developing controls.
• Assessment of turn-taking and cohesion in conversational interactions.

Main Results:

• Significant variations in turn-taking and cohesion were observed between the two SLI subgroups.
• Children with E:SLI and E-R:SLI differed in specific discourse measures.
• Both SLI groups exhibited distinct pragmatic profiles compared to controls.

Conclusions:

• Receptive language skills influence discourse behaviors in children with SLI.
• Future research should consider receptive abilities when studying SLI discourse.
• Normative data for SLI subgroups with varying receptive skills are needed.
