Number Discrimination in 10-Month-Old Infants
Xu, Fei; Arriaga, Rosa I.
British Journal of Developmental Psychology, v25 n1 p103-108 Mar 2007
Two experiments investigated developmental changes in large number discrimination with visual-spatial arrays. Previous studies found that 6-month-old infants were able to discriminate arrays that differ by a ratio of 1:2 but not 2:3. We found that by 10 months, infants were able to reliably discriminate 8 from 12 elements (2:3) but not 8 from 10 elements (4:5). Thus, number discrimination improves in precision during the first year, and these findings converge with studies using auditory stimuli.
