We tested the hypothesis that the previously reported association between a higher body mass index (BMI) and poorer cognition in later adulthood is an artifact of confounding by previous cognitive ability and socioeconomic status. Participants were 1,079 adults aged about 70 years in the Lothian Birth Cohort 1936 Study, on whom there are IQ data from age 11. Cognitive outcome measures included:...

Fifty-one participants (age M = 24.6; education M = 14.4 years) were administered the Wechsler Adult Intelligence Scale - Third Edition (WAIS-III) at baseline and at an interval of either 3 or 6 months later. Full Scale IQ (FSIQ), Verbal IQ (VIQ), Performance IQ (PIQ), Verbal Comprehension Index (VCI), Perceptual Organization Index (POI), and Processing Speed Index (PSI) scores improved signifi...

Abstract Background Children with specific language impairment (SLI) fail to develop age-appropriate despite being apparently normal in other respects. Those children usually have abnormal speech perception noise. This work is designed investigate background noise those children. It included two groups of children: control group (15 typical development) and study (25 diagnosed SLI). All were su...

Duchenne muscular dystrophy (DMD) is a progressive pediatric disorder that affects both muscle and brain. Children with DMD have mean IQ scores that are about one standard deviation lower than population means, with lower Verbal IQ than Performance IQ scores. For the present study, verbal skills and verbal memory skills were examined in males with DMD with the Clinical Evaluation of Language Fu...

Using existing longitudinal data from 570 infants in the Maternal Lifestyle Study, we explored the predictive value of maternal and infant affect and maternal vocalizations during 2 minutes of face-to-face interactions at 4 months on IQ scores at 4.5 and 7 years. After controlling for demographic factors, maternal depression, and prenatal drug exposure, maternal positive affect and maternal pos...

OBJECTIVES To examine the association between smoking history and cognitive function in old age, and whether it remains after controlling for childhood cognitive ability (IQ) and adult socioeconomic status (SES). METHODS In the Lothian Birth Cohort 1936 Study, 1080 men and women, who previously participated in a nationwide IQ-type test in childhood, were followed up at age 70. The association...

OBJECTIVE To examine cognitive outcome in children and adolescents with acute lymphoblastic leukaemia (ALL) in remission, treated with central nervous system prophylactic chemotherapy only. METHOD Thirty-five children and adolescents, age 8.4-15.3 years in long-term remission from ALL, 4.2-12.4 years post diagnosis, without relapse and no pre-diagnosis history of neurodevelopmental disorder w...

One view of common-sense reasoning ability is that it is the ability to perform those tasks with verbal inputs and outputs that have traditionally been difficult for computer systems, but are easy for fairly young children. We administered the verbal part of the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-III, Third Edition) to the ConceptNet 4 system. The IQ test’s questions (e...

The aim of this study was to provide a comprehensive understanding the potential linkages between intelligence and psychopathology across full IQ range, while considering both absolute scores discrepancies them. We drew data from EDEN mother-child birth cohort, gathered at two time points: 5.5 11.5 years age. examined three instruments assessing psychopathology: Strength Difficulties Questionna...
