The numerosity system in preterm newborns is resilient. Both preterm and full-term infants showed similar responses to visual numerosity, suggesting prematurity does not impact this early math skill.

Area of Science:

Neuroscience
Developmental Psychology
Cognitive Science

Background:

Premature birth can lead to parietal cortex damage, affecting magnitude perception and mathematical reasoning.
Preterm children often experience difficulties in school mathematics.

Purpose of the Study:

To investigate the response of preterm newborns to visual numerosity.
To compare preterm and full-term newborns' perception of numerosity after auditory habituation.

Main Methods:

Habituation to auditory stimuli of varying numerosities.
Assessing preferential looking response to visual numerosity in preterm (28-34 weeks gestation) and full-term newborns.

Main Results:

Both preterm and full-term newborns exhibited similar preferential looking responses to visual numerosity.

Both groups showed a preference for the incongruent set after crossmodal habituation.

Conclusions:

The numerosity system appears resistant to the effects of prematurity.
Early mathematical abilities may be less affected by preterm birth than previously thought.
