Co-development among reading, math, science, and verbal working memory in the elementary stage

Area of Science:

• Cognitive Psychology
• Educational Psychology
• Developmental Psychology

Background:

• Understanding the interplay between academic skills and cognitive abilities is crucial for educational interventions.
• Previous research has explored skill development, but within-person effects and mutualism require further investigation.

Purpose of the Study:

• To examine the within-person mutualism among academic skills (reading, math, science) and between these skills and verbal working memory.
• To investigate these relationships in general population samples and specific high- or low-skill groups across elementary grades.

Main Methods:

• Longitudinal study design tracking students from Grade 2 to 5.
• Analysis of academic skills and verbal working memory using a large, diverse sample (N=859-9040).
• Statistical controls for socioeconomic status and gender, with sensitivity analyses.

Main Results:

• Significant mutualism was observed between reading and science skills in all high-ability groups.
• Mutualism between reading/math skills and verbal working memory was specifically found in high-math students.
• These findings were robust after controlling for socioeconomic status and gender.

Conclusions:

• High-skill students, particularly those excelling in math, may benefit from mutualistic relationships between academic skills and cognitive functions.
• This academic mutualism could be driven by intensive, high-quality academic engagement and practice.
• Findings suggest targeted interventions focusing on skill interdependence may enhance academic performance.
