The extraordinary giftedness is apparently a unique manifestation of a mutual interconnection between genes and environment. One of the possible etiological factors of intellectual giftedness is testosterone which is believed to affect the brain organization and function. The aim of our study was to analyze associations between 2D:4D digit ratio (a proxy of prenatal testosterone) and/or salivar...

First, this study examined genetic and environmental sources of variation in performance on a standardised test of academic achievement, the Queensland Core Skills Test (QCST) (Queensland Studies Authority, 2003a). Second, it assessed the genetic correlation among the QCST score and Verbal and Performance IQ measures using the Multidimensional Aptitude Battery (MAB), [Jackson, D. N. (1984) Mult...

A matched samples design was employed to compare WAIS and WAIS-R IQ in UK subjects. The WAIS yielded significantly higher mean Full Scale, Verbal and Performance IQs. The mean differences were 7.5, 6.4 and 7.9 IQ points respectively. The WAIS and WAIS-R samples were broadly representative of the UK adult population in terms of age, sex and social class distribution, and therefore provide tentat...

BACKGROUND H. pylori infection has been linked to iron deficiency anemia, a risk factor of diminished cognitive development. The hypothesis on an association between H. pylori infection and cognitive function was examined in healthy children, independently of socioeconomic and nutritional factors. METHODS A community-based study was conducted among 200 children aged 6-9 years, from different ...

In recent years, there has been a renewed interest in the relationship between intelligence and personality. Extraversion, in particular, has been suggested to influence intelligence, but the direction of this relationship has been controversial (Wolf & Ackerman, 2005). In a young adult sample, the NEO PI-R was completed by 103 pairs of monozygotic twins, 181 pairs of dizygotic twins and 210 of...

Background Whether the Flynn effect (the increase in the populations’ IQ over time) affects the IQ scores of people with learning disability or borderline learning disability remains unclear. The issue is important as the Flynn effect should alter the number of people eligible for health service resources. A comparison of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) with the Wechsler ...

Only a few common variants in the sequence of the genome have been shown to impact cognitive traits. Here we demonstrate that polygenic scores of educational attainment predict specific aspects of childhood cognition, as measured with IQ. Recently, three sequence variants were shown to associate with educational attainment, a confluence phenotype of genetic and environmental factors contributin...

BACKGROUND In recent studies in Bangladesh and elsewhere, exposure to arsenic (As) via drinking water is negatively associated with performance-related aspects of child intelligence (e.g., Perceptual Reasoning, Working Memory) after adjustment for social factors. Because findings are not easily generalizable to the US, we examine this relation in a US population. METHODS In 272 children in gr...

For a prospective study of lead exposure and early development, we recruited pregnant women from a lead smelter town and from an unexposed town in Yugoslavia and followed their children through 7 years of age. In this paper we consider associations between lifetime lead exposure, estimated by the area under the blood lead (BPb) versus time curve (AUC7), and intelligence, with particular concern...
