How Do Components of Executive Function Relate to Taiwanese Sixth Graders' Mathematical Skills?

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Educational Psychology

Background:

• Executive functions are critical for cognitive tasks, especially mathematical abilities in children.
• Understanding the specific links between executive function components and math performance is essential for targeted interventions.

Purpose of the Study:

• To investigate the associations between executive functions (working memory, inhibition, set-shifting) and various mathematical skills in young school-aged children.
• To determine which executive function components best predict different mathematical domains.

Main Methods:

• A cross-sectional study involving 122 typically developing sixth-grade students in Taiwan.
• Participants completed tests assessing working memory (verbal and spatial), inhibition, set-shifting, and mathematical achievement (concepts, computation, applied problems).
• Statistical analyses included correlation and regression, controlling for age, socioeconomic status, and processing speed.

Main Results:

• Significant associations were found between general intellectual ability, working memory, inhibition, set-shifting, and mathematical skills.
• Verbal and spatial working memory positively correlated with all mathematical domains.
• Inhibition was associated with applied problems, and predicted better performance in this domain alongside general intelligence and verbal working memory.

Conclusions:

• Working memory, particularly verbal working memory, is a strong predictor of mathematical concepts, computation, and applied problem-solving skills.
• Inhibition plays a role in applied problem-solving abilities.
• These findings highlight the importance of executive functions in children's mathematical development and inform educational strategies.
