C. Weir et Ws. Millar, THE EFFECTS OF NEONATAL JAUNDICE AND RESPIRATORY COMPLICATIONS ON LEARNING AND HABITUATION IN 5-MONTH-OLD TO 11-MONTH-OLD INFANTS, Journal of child psychology and psychiatry and allied disciplines, 38(2), 1997, pp. 199-206
The influences of neonatal hyperbilirubinemia and respiratory complica
tions were examined in 5- to 11-month-old infants in two studies. One
study focused on habituation performance and the other on contingency
learning. In both experiments, three neonatal jaundice conditions (no
jaundice history, measured bilirubin, phototherapy) were crossed with
two levels of neonatal respiratory risk (no oxygen intervention, oxyge
n intervention). For low respiratory risk subjects there were increasi
ngly adverse effects for both habituation and learning the more severe
the jaundice history. A complex pattern emerged for the high respirat
ory risk groups. Only for the learning task were the results consisten
t with a summative effect of neonatal jaundice and respiratory risk fa
ctors.
