We compared the Wechsler scores of individuals with twice-exceptionality (2e) and giftedness using a three-level Bayesian meta-analysis. Ninety-five effect sizes were calculated from 15 studies (n = 2,106). Results show that individuals with 2e who have learning disabilities perform lower than individuals with giftedness in Full-Scale Intelligence…

Although executive functions have been widely studied in individuals with autism spectrum disorders (ASD), there have been no direct empirical studies of executive abilities in savants with ASD. This study assessed three facets of executive ability (fluency, perseveration and monitoring) in savant artists with ASD, compared to non-talented adults…

Through secondary analysis of data collected in middle school science classrooms, this study (a) compared gifted and regular students' beliefs about the malleability of intelligence in science; (b) investigated whether teaching gifted and talented middle-school students about malleability of the brain and study skills helped them to develop a…

Background: Pitch perception is enhanced among persons with autism. We extended this finding to memory for pitch and melody among school-aged children. Objective: The purpose of this study was to investigate pitch memory in musically untrained children with autism spectrum disorders, aged 7-13 years, and to compare it to that of age- and…

This study investigated whether mothers of children assessed as having gifted/high IQ at 5 years were more likely to scaffold their children in analogical and metacognitive thinking during the infant/toddler period than mothers of children with more typical IQs. The researcher videotaped 21 children in monthly play sessions with their mothers,…

The General Ability Index (GAI) is a composite ability score for the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) that minimizes the impact of tasks involving working memory and processing speed. The goal of the current study was to compare the degree to which the Full Scale IQ (FSIQ) and the GAI predict academic achievement…

Background: The raised incidence of special abilities or "savant skills" among individuals with autism spectrum disorders (ASD) relative to other developmental disorders suggests an association between the traits characteristic of ASD and special abilities. The purpose of this study was to investigate the association between special abilities and…

Speed and efficiency of elemental processing among the gifted were studied by comparing 55 gifted and 53 nongifted junior high school students on elementary cognitive tasks of different complexity. Results reveal that differences are related to requisite processing complexity, suggesting differences in speed and efficiency of lower-order cognitive…

Compared to children with high-average and low-average intelligence quotients, 26 intermediate grade gifted children used fewer moves to solve a combinatorial problem-solving task and exhibited higher metacognitive knowledge on person and strategy variables. Qualitatively different intercorrelational patterns among problem-solving, metacognition,…

The purpose of the present study was to investigate differences in neural information transmission between gifted and normal children involved in scientific hypothesis generation. To investigate changes in the amount of information transmission, the children's averaged-cross mutual information (A-CMI) of EEGs was estimated during their generation…

Examined differences in spontaneous self-regulation on a concept identification task between 23 average and 22 gifted eighth-grade students. Results suggest that self-regulation is a complex composite of cognitive, metacognitive, and motivational factors that underlie sustained efforts to achieve high performance outcomes. (MM)

Mothers of gifted children were significantly more likely than mothers of average children to encourage metacognitive strategies, but mothers of average children provided more direct solutions and talked more about child nontask behavior. (RH)

The pamphlet reviews cognitive and developmental psychology research in which skilled and less skilled performance patterns and mechanisms have been compared. Knowledge has been described, in theory, in terms of an associative network in which concepts are represented as the nodes of the net, and relations between concepts serve as associative…

A sample of 217 students (from grades 4 to 8) who were enrolled in an elementary school science-oriented gifted and talented program were compared to 91 mainstreamed subjects in grades 7 through 10. Assessement instruments included: a battery of Piagetian measures designed to assess combinatorial reasoning, probabilistic reasoning, and the ability…

IDENTIFICATION OF PRODUCTIVE THOUGHT PROCESSES IN INTELLECTUALLY GIFTED CHILDREN WAS BROUGHT WITHIN THE CONTEXT OF CLASSROOM VERBAL ACTIVITY AT THE JUNIOR HIGH SCHOOL LEVEL. RELATIONSHIPS BETWEEN THESE THOUGHT PROCESSES AND CERTAIN VARIABLES THAT MAY AFFECT THEIR OPERATION IN THE CLASSROOM WERE ASSESSED. AREAS EXPLORED WERE COGNITIVE STRUCTURE AND…
