Processing of Scene-Grammar Inconsistencies in Children with Developmental Language Disorder-Insights from Implicit...

Area of Science:

• Neuroscience
• Developmental Psychology
• Linguistics

Background:

• Developmental language disorders (DLD) often co-occur with attentional and social-emotional difficulties.
• The relationship between DLD and visual cognition, specifically scene processing, remains largely unexplored.
• Visuospatial regularities, or scene-grammar, are vital for environmental navigation and share structural similarities with language.

Purpose of the Study:

• To compare implicit and explicit visuospatial knowledge of indoor scenes in children aged 6-10 with and without DLD.
• To investigate the association between visuospatial skills, language, and cognitive abilities in children with DLD.

Main Methods:

• Eye-tracking was used to measure 'dwell times' on semantic and syntactic scene inconsistencies.
• An object-placement task assessed explicit visuospatial knowledge.
• Children's language, visual, and cognitive skills were measured and correlated with performance.

Main Results:

• Visual attention to scene inconsistencies was similar between groups.
• Children with DLD scored lower on a visual perception test.
• Higher language skills correlated with better visuo-cognitive performance, particularly in the DLD group for explicit tasks when controlling for nonverbal cognition.

Conclusions:

• Mild visuospatial processing difficulties may co-occur with DLD, influenced by age and nonverbal cognitive ability.
• Visual cognition and language acquisition are interactive, multimodal processes.
• Understanding the interplay between visual perception and language learning can inform DLD diagnosis and treatment.
