Executive functions in elementary school children with and without problems in written expression

Area of Science:

• Neuroscience
• Developmental Psychology
• Educational Psychology

Background:

• Executive functions are crucial for complex cognitive tasks like writing.
• Difficulties in written expression are common in elementary school children.
• The relationship between executive functions and writing skills requires further investigation.

Purpose of the Study:

• To investigate executive functioning differences in elementary students with and without writing problems.
• To identify specific executive function domains associated with written expression difficulties.
• To explore the predictive power of executive functions and reading decoding on writing quality.

Main Methods:

• Compared executive functions (initiation, sustain, set shifting, inhibition) in 55 elementary students with and without writing problems.
• Controlled for chronological age, ethnicity, gender, socioeconomic status, special education status, attention problems, receptive vocabulary, and reading decoding ability.
• Utilized analysis of covariance (ANCOVA) and multiple regression analyses.

Main Results:

• Children with writing problems performed significantly worse on initiation and set shifting executive function tasks.
• The sustaining domain approached statistical significance.
• Reading decoding ability was the most significant unique predictor of written narrative quality.

Conclusions:

• Executive functions play a role in written expression for elementary students.
• Reading decoding skills are a primary factor influencing writing outcomes.
• Further research should explore additional variables impacting written expression in children.
