Attentional networks efficiency in preterm children

Recent Studies have reported specific executive and attentional deficits in preterm children. However, the majority of this research has used multidetermined tasks to assess these abilities, and the interpretation of the results lacks an explicit theoretical backdrop to better understand the origin of the difficulties observed. In the present study, we used the Child Attention Network Task (Child ANT; Rueda et al. 2004) to assess the efficiency of the alerting, orienting and executive control networks. We compared the performance of 25 preterm children (gestational age <= 32 weeks) to 25 full-term children, all between 5(1)/(2) and 6(1)/(2) years of age. Results showed that, as compared to full-term children, preterm children were slower oil all conditions of the Child ANT and had a specific deficit ill executive control abilities. We also observed a significantly higher correlation between the orienting and executive control networks in the preterm group, suggesting less differentiation of these two networks in this population.
