Few studies have assessed visuo-spatial working memory and inhibition in attention-deficit/hyperactivity disorder (ADHD) by recording saccades and consequently little additional knowledge has been gathered on oculomotor functioning in ADHD. Moreover, this is the first study to report the performance of non-affected siblings of children with ADHD, which may(More)
AIM We aimed to clarify the underpinnings of widespread visuomotor deficits in very preterm children. METHOD Fifty-eight very preterm children (26 males, 32 females; mean [SD] age 7 y 6 mo [5 mo], gestational age 29.2 wks [1.6]; birthweight 1237 g [336]), recruited from a tertiary level neonatal intensive care unit, and 64 age-matched, comparison children(More)
INTRODUCTION This study aimed to establish visual search performance and attention functioning in very preterm/very low birth weight (VP/VLBW) children using novel and well established measures, and to study their contribution to intellectual functioning. METHODS Visual search and attention network efficiency were assessed in 108 VP/VLBW children and 72(More)
It is generally thought that deficits in response inhibition form an important area of dysfunction in patients with attention-deficit/hyperactivity disorder (ADHD). However, recent research using visual search paradigms seems to suggest that these inhibitory deficits do not extend towards inhibiting irrelevant distractors. Using an oculomotor capture task,(More)
A range of neurobehavioral impairments, including impaired visual perception and visual-motor integration, are found in very preterm born children, but reported findings show great variability. We aimed to aggregate the existing literature using meta-analysis, in order to provide robust estimates of the effect of very preterm birth on visual perceptive and(More)
OBJECTIVE To evaluate the effect of the Infant Behavioral Assessment and Intervention Program (IBAIP) in very low birth weight (VLBW) infants on cognitive, neuromotor, and behavioral development at 5.5 years corrected age (CA). STUDY DESIGN In a randomized controlled trial, 86 VLBW infants received post discharge IBAIP intervention until 6 months CA, and(More)
AIM To examine visual sensory and perceptive functions, study their interrelations, and explore associations between visual dysfunctions and intelligence in very preterm/very-low-birthweight (VP/VLBW) children. METHOD One-hundred and sixteen VP/VLBW children (57 males, 59 females; mean gestational age 30.1 wks, SD 2.3; mean corrected age 5 y 6 mo, SD 1(More)
AIM To extend understanding of impaired motor functioning of very preterm (VP)/very low birth weight (VLBW) children by investigating its relationship with visual attention, visual and visual-motor functioning. METHODS Motor functioning (Movement Assessment Battery for Children, MABC-2; Manual Dexterity, Aiming & Catching, and Balance component), as well(More)
