Description
Background
Preterm birth is closely associated with neurocognitive impairment in childhood including increased risk for social difficulties. Eye tracking objectively assesses eye‐gaze behaviour in response to visual stimuli, which permits inference about underlying cognitive processes. We tested the hypothesis that social orienting in infancy is altered by preterm birth.
Methods
Fifty preterm infants with mean (range) gestational age (GA) at birth of 29+1 (23+2–33+0) weeks and 50 term infants with mean (range) GA at birth 40+2 (37+0–42+3) weeks underwent eye tracking at median age of 7 months. Infants were presented with three categories of social stimuli of increasing complexity. Time to first fixate (TFF) and looking time (LT) on areas of interest (AoIs) were recorded using remote eye tracking.
Results
Preterm infants consistently fixated for a shorter time on social content than term infants across all three tasks …
