The current study used four measures of executive functioning to assess the effect of EPon these domains and examine associations of outcomes in the EP group with neonatalrisk factors. Another aim was to conduct exploratory analyses using outcome variablesthat were created to isolate components of EF. Findings revealed that the EP groupperformed more poorly than the term group on all outcome measures, and on a few of thetasks after controlling for crystallized intelligence. Some neonatal complicationspredicted poorer EF after accounting for background and environmental characteristics.The findings suggest pervasive cognitive deficits in children with EP at school entry,raise the possibility of select deficits in certain domains of EF, show that EF are related tothe degree of neonatal risk, and demonstrate deficits in children with EP on measure thatassess specific aspects of EF.
