Executive function in children with signs of specific learning disorders

Area of Science:

• Neuroscience
• Developmental Psychology
• Educational Psychology

Background:

• Executive functions (EFs) are crucial for cognitive and behavioral regulation.
• Specific Learning Disorders (sSLDs) are associated with diverse cognitive challenges.
• Understanding distinct EF profiles in sSLD subtypes is essential for targeted interventions.

Purpose of the Study:

• To compare executive functions (EFs) in children with decoding, reading comprehension, spelling, and calculation deficits against typically developing (TD) children.
• To identify specific EF profiles associated with each learning deficit subtype.
• To explore cognitive and behavioral manifestations of EFs in children with signs of Specific Learning Disorders (sSLD).

Main Methods:

• A sample of 93 children with sSLD and 28 TD children (aged 7-13) were assessed.
• EFs were evaluated using performance-based tests and parent/teacher questionnaires.
• Statistical analyses included ANOVAs, correlation, and factorial analyses.

Main Results:

• Children with decoding deficits showed impaired interference control and enhanced cognitive flexibility, with self-regulation challenges.
• Reading comprehension deficits were linked to working memory (WM) and planning impairments without behavioral impact.
• Calculation deficits involved poor WM and interference control, with reported self-regulation and organizational difficulties.
• A distinct EF profile for spelling deficits was not identified.

Conclusions:

• Distinct cognitive and behavioral executive function profiles exist for different learning deficit subtypes.
• These findings highlight the functional variability among children with learning deficits.
• Tailoring interventions to specific EF profiles is crucial for academic success and daily organization.
