Infants use different mechanisms to make small and large number ordinal judgments

► Examines infants’ ability to judge the larger of two quantities. ► Tests whether small and large numbers represented by different mechanisms. ► Infants make accurate ordinal judgments for exclusively small or large sets. ► Infants fail when comparing small and large sets. ► Representations for sma...

Zusammenfassung:	► Examines infants’ ability to judge the larger of two quantities. ► Tests whether small and large numbers represented by different mechanisms. ► Infants make accurate ordinal judgments for exclusively small or large sets. ► Infants fail when comparing small and large sets. ► Representations for small and large numbers are incommensurable. Previous research has shown indirectly that infants may use two different mechanisms—an object tracking system and an analog magnitude mechanism—to represent small (
