BACKGROUND High levels of behaviour problems are found in children with language impairments, but less is known about the level and nature of language impairment in children with severe behavioural problems. In particular, previous data suggest that at primary age, receptive impairments are more closely related to behaviour problems, whereas expressive language has a closer link at a later age....

BACKGROUND Studies have documented a positive relationship between regular breakfast consumption and cognitive outcomes in youth. However, most of these studies have emphasized specific measures of cognition rather than cognitive performance as a broad construct (e.g., IQ test scores) and have been limited to Western samples of school-age children and adolescents. This study aims to extend the ...

A meta-analysis was performed on the 133 cognitive and behavioral papers in autism using comparison groups in the 1999-2002 period. High-functioning (average IQ: 84.7), adolescents (average, 14.4 years) are largely dominant. IQ is the most frequent matching variable in use (51.2%). The instruments that are most frequently used to determine IQ or general level are Wechsler scales (46.9%), Britis...

OBJECTIVE To perform a complete Intelligence quotient (IQ) measurement (verbal, performance, and total) and subsequently, to compare executive function (EF) measurements in subgroups of children with attention deficit-hyperactivity disorder (ADHD) with a control group. METHOD We studied a group of children from 7-12 years of age from public elementary schools. Children were selected by means ...

OBJECTIVE This study of a birth cohort in the city of Tongliang in Chongqing, China, evaluated the relationship between two prenatal exposures (polycyclic aromatic hydrocarbons(PAH) and environmental tobacco smoke(ETS)) and child intelligence quotient (IQ) as measured by the Wechsler Preschool and Primary Scale of Intelligence at age 5 years. A coal-fired power plant was the major source of amb...

OBJECTIVES To determine whether perinatal nutrition influences cognitive function at 7 1/2 - 8 years in children born preterm. DESIGN Randomised, blinded nutritional intervention trial. Blinded follow up at 7 1/2 - 8 years. SETTING Intervention phase in two neonatal units; follow up in a clinic or school setting. SUBJECTS 424 preterm infants who weighed under 1850 g at birth; 360 of those...

BACKGROUND AND PURPOSE Neonatal arterial ischemic stroke (AIS) affects a surprisingly large number of children each year, yet little is known about the long-term neuropsychological implications. METHODS Using age-appropriate Wechsler scales of intellectual ability, this longitudinal study examined 26 children with a history of acutely diagnosed unilateral neonatal AIS as preschoolers (3 years...

Background: Autism spectrum disorder (ASD) was once considered to be highly associated with intellectual disability and to show a characteristic IQ profile; with strengths in Performance over Verbal abilities and a distinctive pattern of ‘peaks’ and ‘troughs’ at the subtest level. However, there is little data from epidemiological studies. Method: Comprehensive clinical assessments were conduct...

Intelligence in 20 presymptomatic subjects with an increased risk (> 95%) for carrying the gene for Huntington's disease (HD) was studied in a prospective, case-control, single blind study. No significant differences between the groups were detected for intelligence indices and subtest scores (Wechsler Adult Intelligence Scale). The high level of the performance IQ and the significant discrepan...

The current study addresses gaps in our understanding of the relationship between creative cognition, intelligence (IQ), and executive functioning (EF). Undergraduate students completed an IQ test, verbal figural divergent thinking (DT) tests, a self-assessment EF, across four sessions. Participant data (N = 199) were analyzed using linear regression PROCESS moderation models. Results demonstra...
