Seven-month-olds detect ordinal numerical relationships within temporal sequences

J Exp Child Psychol. 2010 Nov;107(3):359-67. doi: 10.1016/j.jecp.2010.05.005. Epub 2010 Jun 25.


Previous evidence has shown that 11-month-olds represent ordinal relations between purely numerical values, whereas younger infants require a confluence of numerical and non-numerical cues. In this study, we show that when multiple featural cues (i.e., color and shape) are provided, 7-month-olds detect reversals in the ordinal direction of numerical sequences relying solely on number when non-numerical quantitative cues are controlled. These results provide evidence for the influence of featural information and multiple cue integration on infants' proneness to detect ordinal numerical information.
