Early math skills rely on different abilities. While performance uses number and cognitive skills, development specifically needs verbal working memory, showing distinct underlying factors.
Area of Science:
- Cognitive Psychology
- Developmental Psychology
- Educational Psychology
Background:
- Understanding the foundational skills for early arithmetic is crucial for educational interventions.
- Distinguishing between factors influencing arithmetic performance and those driving skill development is key.
Purpose of the Study:
- To identify the cognitive and numerical abilities underpinning early mental arithmetic learning (skill development).
- To compare these underlying abilities with those supporting early arithmetic performance.
Main Methods:
- Assessed 265 children on counting knowledge, symbolic magnitude comparison, number line estimation, logical reasoning, verbal working memory, spatial processing, phonological processing, and general processing speed.
- Utilized a latent change score model to analyze longitudinal data from first to second grade.
Main Results:
- Arithmetic performance was supported by counting knowledge, number line estimation, logical reasoning, spatial processing, phonological processing, and general processing speed.
- Arithmetic development (skill change) was uniquely supported by verbal working memory.
Conclusions:
- The cognitive and numerical abilities supporting arithmetic performance differ from those supporting its development.
- Early arithmetic performance relies on a blend of number and cognitive skills, while development is primarily driven by verbal working memory.
