Key Points

Findings support the idea that number sense may be tied to brain lateralization, impacting cognitive processing involved in mathematics.
Key evidence suggests that chicks demonstrate a left-to-right mental number line, informing how they perceive numerical values.
Observational analysis using experimental methods on domestic chicks to explore cognitive mappings of number.
Implications point to the importance of brain hemisphere functions in developing numeric understanding, warranting further research.

Implication

Experiments reveal links between brain lateralization and the mental number line in domestic chicks, suggesting an innate 'number sense'.

Abstract

Experiments on domestic chicks shed light on the links between brain lateralization and the left-to-right mental number line.
