Electrophysiological Evidence of Space‐Number Associations in 9‐Month‐Old Infants
Infant research is providing accumulating evidence that number‐space mappings appear early in development. Here, a Posner cueing paradigm was used to investigate the neural mechanisms underpinning the attentional bias induced by nonsymbolic numerical cues in 9‐month‐old infants (N = 32). Event‐relat...

description | Infant research is providing accumulating evidence that number‐space mappings appear early in development. Here, a Posner cueing paradigm was used to investigate the neural mechanisms underpinning the attentional bias induced by nonsymbolic numerical cues in 9‐month‐old infants (N = 32). Event‐related potentials and saccadic reaction time were measured to the onset of a peripheral target flashing right after the offset of a centered small or large numerical cue, with the location of the target being either congruent or incongruent with the number’s relative position on a left‐to‐right oriented representational continuum. Results indicated that the cueing effect induced by numbers on infants’ orienting of eye gaze brings about sensory facilitation in processing visual information at the cued location. |
