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…

The primary role of NTC (Nikola Tesla Center) is to use new discoveries in the field of neurology in classrooms and in everyday life. This learning program consists of various activities and games for children. This experimental research was carried out in one government primary school in Canakkale, Turkey. 27 students from the third grade (17…

Evidence from twin studies points to substantial environmental influences on intelligence, but the specifics of this influence are unclear. This study examined one developmental process that potentially causes intelligence differences: learning to read. In 1,890 twin pairs tested at 7, 9, 10, 12, and 16 years, a cross-lagged…

The present study examined the moderating effects of intellectual functioning and ASD symptom severity on the relation between age and adaptive functioning in 220 youth with autism spectrum disorder (ASD). Regression analysis indicated that intellectual functioning and ASD symptom severity moderated the relation between age and adaptive…

Distributed brain areas support intellectual abilities in adults. How structural maturation of these areas in childhood enables development of intelligence is not established. Neuroimaging can be used to monitor brain development, but studies to date have typically considered single imaging modalities. To explore the impact of structural brain…

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…

This study investigated intellectual development in 4-7 years old Greek and Chinese children. They were examined on speeded performance, working memory, reasoning, and self-awareness tasks in order to investigate possible effects of learning the Chinese logographic system on possible differences in intellectual development between these ethnic…

Structural equation modeling (SEM) was used to examine the development of intellectual functioning in 145 school-age pairs of siblings. Each pair included one child with Fragile X syndrome (FXS) and one unaffected sibling. All pairs of children were evaluated on the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) at time 1 and 80…

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…

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…

The "elemental" refers to the essentials of the contents that make them accessible to a child. The effects on a child of contents that are mastered are the "fundamental". In a fruitful didactic unlocking (presentation) it is possible for a child to achieve considerably more insight than merely an understanding of the learning…

Investigates relationships between family structure variables and 17 measures describing children's intellectual, psychosocial, and physical growth. Subjects were a 10 percent random sample of a Danish cohort consisting of children born in a Copenhagen hospital between September 1959 and December 1961; 857 subjects were followed to age 19.…

A recognition memory experiment with 8-, 11- and 20-year-olds investigated the hypothesis that, with age, semantic encoding becomes increasingly important relative to acoustic encoding. (CM)

Utilizing data from the WISC-R standardization sample, Gutkin presented formulae to calculate factorially pure verbal comprehension, perceptual organization, and freedom from distractibility deviation quotients. Data are presented concerning standard errors of measurement and score discrepancies that are required for statistical significance…

This study investigates age differences in children's semantic expectations regarding causal relations in stories about three realistic goal situations (being friendly, getting a dog, and doing chores). Twenty children at each of three age levels (ages 6, 9, and 12) were asked to produce stories and answer probe questions about wanting and not…
