Aim This study aimed to compare a broad array of neurocognitive functions (processing speed, aspects of attention, executive functioning, visual-motor coordination, and both face and emotion recognition) in very preterm and term-born children and to identify perinatal risk factors for neurocognitive dysfunctions. Method Children who were born very preterm (n=102; 46 males, 56 females), defined as a gestational age of less than 30weeks and/or birthweight under 1000g, and a comparison group of term-born children (n=95; 40 males, 55 females) were assessed at age 5 with the Wechsler Preschool and Primary Scale of Intelligence, Stop Signal Task, several tasks of the Amsterdam Neuropsychological Tasks, and a Digit Span task. Results When sociodemographic characteristics were taken into account, very preterm children scored worse than term-born children on all neurocognitive functions, except on tasks measuring inhibition and sustained attention, for which results were inconclusive. Effect sizes for group effects were small to medium (r
