With just one exception, all of the volumes in Terman's Genetic Studies of Genius report the results of a longitudinal study of more than a thousand intellectually gifted children. That single exception is Volume II, Cox's single-authored "The Early Mental Traits of Three Hundred Geniuses," which instead was a retrospective study of 301…

Background: Children with cerebral palsy (CP) are at greater risk for a limited intellectual development than typically developing children. Little information is available which children with CP are most at risk. This study aimed to describe the development of non-verbal intellectual capacity of school-age children with CP and to examine the…

Two groups of adolescents (N = 114), 61 identified-gifted adolescents (M = 22, F = 39) and 51 vocational school adolescents (M = 27, F = 26), were compared on the Overexcitability Questionnaire. Each of the five Overexcitability (OE) scores--Psychomotor, Sensual, Imaginational, Intellectual, and Emotional--was subjected to a two-way ANOVA by…

The debate over whether intelligence is largely fixed or malleable is not over. What is most exciting, however, is the research from social psychology, developmental psychology, cognitive psychology, and neuroscience that is highlighting just how malleable intelligence is. Differences in achievement among racial, ethnic, or gender groups have…

Background: Children with learning disabilities are identified by their severe learning problems and their deficient school achievement. On the other hand, children with sub-average school achievement "and" sub-average intellectual development are thought to suffer from a general intellectual delay rather than from specific learning disabilities.…

Aims: Our aim was to examine intellectual development in children with congenital hemiplegia from early childhood to adolescence. Method: Full-scale IQ (FIQ), Verbal IQ (VIQ), and Performance IQ (PIQ) scores were measured in 32 participants (19 males, 13 females) with congenital hemiplegia at mean ages of 4 years 6 months (SD 7mo; 31…

In this meta-analysis of 75 studies on more than 3,888 children in 19 different countries, the intellectual development of children living in children's homes (orphanages) was compared with that of children living with their (foster) families. Children growing up in children's homes showed lower IQ's than did children growing up in a family…

The offspring of mothers with epilepsy are considered to be at developmental risk during pregnancy from: (1) generalized maternal seizures (hypoxia); (2) teratogenicity of antiepileptic drugs (AEDs); and (3) adverse socio-familial conditions associated with having a chronically sick mother. Sixty-seven children of mothers with epilepsy and 49…

In January, W. H. Brady Scholar Charles Murray stepped back from current education debates about reauthorization of the 2002 No Child Left Behind Act and education funding in the president's budget to ask more fundamental questions about the goals that should shape American education in the future. This "On the Issues" is adapted from…

Lowered intelligence relative to controls is evident by mid-childhood in children with sickle cell disease. There is consensus that brain infarct contributes to this deficit, but the subtle lowering of IQ in children with normal MRI scans might be accounted for by chronic systemic complications leading to insufficient oxygen delivery to the brain.…

Two studies were conducted to explore mathematical precocity in young children. Study 1 examined mathematically gifted first and third graders' working memory development. The results showed that mathematically gifted children's working memory growth was similar to that expected of their age peers. Study 2 examined changes in mathematically gifted…
