Arithmetic skills in kindergarten children with developmental language disorders

Area of Science:

• Developmental psychology
• Neuroscience
• Pediatric learning disabilities

Background:

• Specific learning disabilities in arithmetic, such as dyscalculia, are frequently observed in children with developmental language disorders (DLD).
• Understanding the relationship between DLD and arithmetic skills is crucial for early intervention and educational support.

Purpose of the Study:

• To investigate arithmetic skills in kindergarten children with DLD.
• To determine if DLD is associated with impaired arithmetic abilities.
• To correlate specific arithmetic deficits with language syndromes in these children.

Main Methods:

• A cohort of 42 kindergarten children with DLD and matched controls were assessed.
• Participants underwent evaluations including an arithmetic battery, neurological examination, IQ testing (WPPSI/WISC-R), and language assessment (CELF-R).
• Attention deficit hyperactivity disorder (ADHD) was diagnosed using psychological assessments and behavior questionnaires.

Main Results:

• Children with DLD showed significantly poorer performance on arithmetic tasks compared to controls (p < 0.01).
• Impairments in reasoning principles and arithmetic operations were linked to both receptive and expressive language deficits.
• Poor performance in counting principles was primarily associated with expressive language deficits.

Conclusions:

• Arithmetic impairment in children with DLD is pervasive, affecting a wide range of skills.
• While most arithmetic skill deficits correlate with global language disturbances, counting deficits are specifically linked to expressive language issues.
• Early identification and support are essential for children with DLD facing challenges in both language and arithmetic development.
