How executive functions predict development in syntactic complexity of narrative writing in the upper elementary...

Area of Science:

• Developmental Psychology
• Educational Psychology
• Linguistics

Background:

• Writing development in upper elementary grades involves complex cognitive and linguistic processes.
• Understanding predictors of writing growth is crucial for effective educational interventions.
• Previous research has identified various factors influencing writing, but the interplay between oral language, executive functions, and syntactic development in narrative writing needs further exploration.

Purpose of the Study:

• To investigate the contributions of transcription skills, oral language abilities, and executive functions to the growth of narrative writing.
• To identify specific executive functions (inhibition, planning) and oral language components (oral grammar) that predict syntactic complexity in narrative writing.
• To examine developmental changes in narrative writing, focusing on text length, content, and syntactic complexity between fourth and sixth grade.

Main Methods:

• Longitudinal study tracking narrative writing development in students from fourth to sixth grade.
• Path analysis was used to model the relationships between initial writing skills, oral language, executive functions, and later writing outcomes.
• Assessment of transcription skills, oral language proficiency (including oral grammar), executive functions (inhibition, planning), and narrative writing quality (text length, content, syntactic complexity).

Main Results:

• Narrative writing showed a clear developmental progression in syntactic complexity, although text length and story content did not significantly increase with age.
• Initial syntactic complexity, oral grammar, inhibition, and planning were significant predictors of later syntactic complexity in narrative writing.
• Transcription skills did not emerge as a direct predictor of syntactic complexity growth in this model.

Conclusions:

• Syntactic complexity is a relevant developmental marker for narrative writing in upper elementary students.
• Executive functions, specifically inhibition and planning, play a significant role in the development of syntactic complexity in writing.
• Oral grammar is a crucial foundation for developing more complex sentence structures in written narratives, highlighting the interconnectedness of oral and written language skills.
