title: The relationship between encoding, discriminative capacities and perinatal risk status in 4-12-month old infants.
abstract: Response decrement and recovery to a novel visual stimulus was examined in 4-12-mth old infants. High (HR) and low (LR) perinatal risk groups were compared to well babies. For abstract stimuli, well babies showed response decrement and recovery to novelty; LR infants revealed some decrement, but no recovery; and the HR group failed to show either. Using face stimuli (Experiment 2) all groups showed decrement and recovery. Cluster analyses revealed that HR infants were more likely to be found in low information-gain clusters. Infants of lower GA who required perinatal respiratory intervention showed less efficient encoding and poorer discrimination of abstract stimuli.
