Intelligence tests are widely assumed to measure maximal intellectual performance, and predictive associations between intelligence quotient (IQ) scores and later-life outcomes are typically interpreted as unbiased estimates of the effect of intellectual ability on academic, professional, and social life outcomes. The current investigation critically examines these assumptions and finds evidenc...

OBJECTIVE To find the frequency of regular breakfast consumption among Pakistani teenagers while the other objective was to find out the association between breakfast consumers (BC) and intelligence quotient (IQ). METHODS This comparative cross sectional study was conducted on 102 students of a Public School Rawalpindi from August 2013 to January 2014. Participants were categorised into two g...

The relationship of serum uric acid concentration and school achievement was studied in 467 high school children in Tecumseh, Michigan. Serum uric acid (SUA) was determined by the spectrophotometric method. No statistically significant relationships were found between SUA and intelligence quotient or average academic grades. There was also no significant difference in SUA among the overachiever...

OBJECTIVE: To find the effect of iron deficiency anemia (IDA) on intelligence quotient (IQ) in school going children Peshawar, Pakistan. METHODS: In this cross-sectional study a total 153 (male and female) age 7-11 years were included. Socio-demographic questionnaire was designed for collection data. Blood specimens collected ethylenediaminetetraacetic acid (EDTA) gel tubes. Complete blood coun...

There is mixed evidence about the predictive validity of the Griffiths mental developmental scales. This study aimed to assess the predictive value of developmental assessments of children in their second year using the Griffiths mental development scales for neuro-developmental status at five years using the Wechsler preschool and primary scale of intelligence, revised (WPPSI-R). In a longitud...

Previous studies have found correlations between uneven intellectual development and autistic symptom severity but thus far each study has looked only at specific types of discrepancy score and results have been inconsistent. This study used the Autism Spectrum Quotient (AQ) and the British Ability Scales (second edition) to look for a correlation between autistic-like traits and an overall ind...

The relationship between creativity and academic achievement is investigated in this study to understand the nature of these relationships in the intelligence continuum among 497 Form Four Malaysian students. Intelligence was measured using Cattel’s Culture Fair Intelligence Tests and Creativity was measured using Torrance Tests of Creative Thinking. Four groups were formed based on creativity ...

Mounting evidence indicates that early-life exposure to particulate air pollutants pose threats to children's cognitive development, but studies about the neurotoxic effects associated with exposures during adolescence remain unclear. We examined whether exposure to ambient fine particles (PM2.5) at residential locations affects intelligence quotient (IQ) during pre-/early- adolescence (ages 9-...

An abbreviated Wechsler Adult Intelligence Scale Revised (WAIS-R) was used to assess verbal and arithmetical cognitive performance in 55 subjects with myotonic dystrophy (DM), covering all grades of disease severity, and 31 controls at 50% risk of inheriting DM. Scaled scores from the assessment were converted into an intelligence quotient (IQ) estimation on each person. Significant IQ differen...
