Prosody and gestures help pragmatic processing in children with Developmental Language Disorder.

Area of Science:

• Developmental Psychology
• Linguistics
• Speech and Language Therapy

Background:

• Typically developing children use prosody and gestures for pragmatic understanding.
• Children with Developmental Language Disorder (DLD) often struggle with language structure and pragmatics.

Purpose of the Study:

• To investigate how prosodic and gestural cues aid pragmatic meaning processing in children with DLD.
• To compare cue benefits for less complex (interrogative) versus more complex (indirect requests) meanings.
• To examine age-related differences in cue utilization for children with DLD.

Main Methods:

• Two visual-world eye-tracking tasks involving 34 children with DLD and 45 typically developing controls (ages 5-10).
• Manipulation of prosodic, multimodal, and no-enhancement cues for pragmatic meanings.
• Analysis of eye gaze data to assess target image preference and interpretation bias.

Main Results:

• All children improved comprehension with prosodic and multimodal cues for simpler meanings.
• Younger children with DLD showed lower accuracy despite cue enhancement.
• Multimodal cues particularly aided older children with DLD in processing complex meanings.
• Children with DLD exhibited less clear target preference with prosodic/bodily cues but multimodal cues reduced literal bias for indirect requests.

Conclusions:

• Prosodic and bodily cues are crucial for processing pragmatic meanings of varying complexity, especially for children with DLD.
• Multimodal cueing offers significant support for children with DLD, particularly for more complex pragmatic tasks.
• Findings inform communication strategies for professionals working with children with DLD.
