From infancy to adulthood: the development of numerical abilities

Area of Science:

• Cognitive Development
• Mathematical Cognition
• Educational Psychology

Background:

• Quantitative skills develop across the lifespan, from infancy through old age.
• Early emerging numerical competencies appear to be biologically predetermined and universal.
• Later acquired mathematical abilities are influenced by formal education and societal factors.

Purpose of the Study:

• To review developmental and school-related changes in basic number, counting, and arithmetic skills.
• To differentiate between inherently based and educationally acquired quantitative competencies.
• To explore the implications of variability in secondary quantitative abilities for research on cognitive impairments.

Main Methods:

• Literature review of developmental changes in quantitative skills.
• Analysis of the origins of basic numerical competencies (biological primary vs. secondary).
• Examination of factors influencing the development of school-based mathematical abilities.

Main Results:

• Infancy and preschool quantitative skills are largely universal, reflecting an inherent cognitive system.
• School-acquired mathematical abilities lack a direct inherent foundation and show significant cross-cultural and generational variation.
• Variability in secondary quantitative skills complicates the study of pathological conditions (e.g., dyscalculia) and aging effects.

Conclusions:

• Distinguishes between innate, universal early math skills and learned, variable later math skills.
• Highlights the crucial role of education in shaping mathematical abilities beyond basic numeracy.
• Suggests that individual differences and educational contexts are key factors in understanding mathematical development and disorders.
