Human brains compute numbers differently based on language. While basic number sense exists in preverbal infants and monkeys, language acquisition shapes its development in young children.

Area of Science:

  • Developmental science
  • Cognitive neuroscience
  • Comparative psychology

Background:

  • Understanding numerical cognition in humans and non-human animals is crucial for developmental science.
  • Investigating the role of language in the development of numerical abilities is a key area of research.

Purpose of the Study:

  • To explore how brains compute numbers, with and without language.
  • To compare numerical abilities in preverbal infants, young children speaking different languages, and monkeys.

Main Methods:

  • Comparative analysis of numerical task performance.
  • Cross-linguistic study involving children in France and England.
  • Assessment of verbal reactions in young children.

Main Results:

Related Experiment Videos

  • A shared basic arithmetic ability for small numbers exists in monkeys, preverbal infants, and humans.
  • Human infants' numerical development shows language-specific performance patterns.
  • Language acquisition significantly influences the trajectory of early numerical knowledge.

Conclusions:

  • Early numerical cognition is influenced by both innate abilities and linguistic input.
  • Language plays a critical role in shaping the development of human numerical competence.
  • Cross-species and cross-linguistic comparisons offer insights into the evolution and development of number sense.
