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…

This study explores the differences in the motivational profiles of under-achieving gifted students and high-achieving gifted and non-gifted students. In comparison to their high-achieving peers, under-achieving gifted students reported weaker motivational orientations, in both achievement and social goals, as well as in intrinsic motivation.…

Mathematical giftedness (MG) is an intriguing phenomenon, the nature of which has yet to be sufficiently explored. This study goes a step further in understanding how MG is related to expertise in mathematics (EM) and general giftedness (G). Cognitive testing was conducted among 197 high school students with different levels of G and of EM. Based…

The objective of this study was to examine the different development characteristics of gifted children during the preschool period in comparison with normal developing children according to family observation. For this purpose, face-to-face interviews were carried out with the parents of 112 children identified as gifted and data regarding the…

A few studies suggest that gifted children with dyslexia have better literacy skills than averagely intelligent children with dyslexia. This finding aligns with the hypothesis that giftedness-related factors provide compensation for poor reading. The present study investigated whether, as in the native language (NL), the level of foreign language…

This study sought comprehension of several specifics concerning the self-concept of gifted high school students in France. Eighty-four gifted high school students (IQ = 130) between the ages of 13 and 18 were matched with 84 nongifted high school students possessing the same gender, family background, and academic characteristics. Each of these…

This study investigated how gifted children with dyslexia might be able to mask literacy problems and the role of possible compensatory mechanisms. The sample consisted of 121 Dutch primary school children that were divided over four groups (typically developing [TD] children, children with dyslexia, gifted children, gifted children with…

The Naglieri Nonverbal Ability Test, Second Edition (NNAT2), is used widely to screen students for possible inclusion in talent development programs. The NNAT2 claims to provide a more culturally neutral evaluation of general ability than tests such as Form 6 of the Cognitive Abilities Test (CogAT6), which has Verbal and Quantitative batteries in…

A considerable amount of recent evidence suggests that speed of information processing (SIP) may be related to general giftedness as well as contributing to higher mathematical ability. To date, no study has examined SIP associated with both general giftedness (G) and excellence in mathematics (EM). This paper presents a part of more extensive…

Computer-Assisted Language Learning (CALL) has gained increasing acceptance since it provides learners with abundant resources. Most researches confirm the beneficial effect of CALL on English as a Foreign Language (EFL) learners' cognitive, metacognitive, and affective developments. However, the diversity of students' intelligence is associated…

This study examined students' understanding of diagrams and their use of diagrams as tools to solve mathematical word problems. Students with learning disabilities (LD), typically achieving students, and gifted students in Grades 4 through 7 ("N" = 95) participated. Students were presented with novel mathematical word problem-solving…

The cognitive and academic profiles of high ability students with autism spectrum disorder were examined. Inclusion criteria were a diagnosis of autism (high functioning) or Asperger syndrome and at least one ability and/or achievement index standard score of 120 or above. Results indicated that despite the restricted range of cognitive abilities,…

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…

Coding and maze subtests were used to evaluate children for verification of giftedness. Scaled scores on mazes were significantly higher though the proportion of children meeting the established criterion was similar for either subtest in the Full Scale Scores. Supports selective inclusion of mazes in gifted assessment. (Author/JAC)

The Wechsler Intelligence Scale for Children Revised (WISC-R) was administered to 34 elementary students scoring "gifted" on the Otis, Iowa, and SRBCSS (Scale for Rating Behavioral Characteristics of Superior Students). Results indicated a combination of the Otis, Iowa, and SRBCSS was moderately effective in predicting the Full Scale…
