The aim of the present study is to develop a national non-verbal cognitive ability test in Turkey. Test items were developed during the first stage and applied as a pilot study on 3,073 children in the age interval of 4 to 13. The test was given its final form based on the values of item difficulty, item distinctiveness, item total score…

With the number of new and revised nonverbal and language-reduced tests of cognitive ability, selection and interpretation of appropriate measures can be complicated. Seven nonverbal or language-reduced tests with normative data collected within the last 15 years were evaluated. Besides evaluating technical adequacy, other variables affecting test…

This qualitative study aimed to discover teachers' perceptions about the effectiveness of using the nonverbal Cognitive Abilities Screening Test (CogAT) in identifying gifted and talented children. The study's sample of six teachers participated in standardizing the Jordanian version of the CogAT. Teachers attended a focus group discussion, and…

In this study, we examined the factor structure, reliability, and external validity of scores from the Comprehensive Test of Nonverbal Intelligence-Second Edition (CTONI-2) using an independent sample of young adults currently enrolled in a postsecondary institution. Although the subtests appear to be measuring general intelligence, the aggregate…

The relationship between intelligence and creativity remains controversial. The present research explored this issue by studying the role of fluid intelligence (Gf) in the generation of creative metaphors. Participants (n = 132 young adults) completed six nonverbal tests of Gf (primarily tests of inductive reasoning) and were then asked to create…

This study examined whether there are processing differences between children with Down syndrome (DS; n = 22; 7 years 8 months to 13 years 10 months) and typically developing children (TD; n = 22; 6 years 6 months to 10 years 10 months), matched for receptive vocabulary. The TD children performed better on tests of nonverbal intelligence…

It is not clear from research whether, or to what extent, reading comprehension is impaired in adults who have learning disabilities (LD). The influence of perceptual organization (PO) and phonological awareness (PA) on reading comprehension was investigated. PO and PA are cognitive functions that have been examined in previous research for their…

Verbal and quantitative reasoning tests provide valuable information about cognitive abilities that are important to academic success. Information about these abilities may be particularly valuable to teachers of students who are English-language learners (ELL), because leveraging reasoning skills to support comprehension is a critical aptitude…

This study examines whether MidYIS and YELLIS cognitive ability tests (CATs) are appropriate methods for the identification of giftedness in Design and Technology. A key rationale for the study was whether CATs and able to identify those students with the aptitudes considered of importance to identifying giftedness in Design and Technology and…

In this study, the authors compare the validity of three nonverbal tests for the purpose of identifying academically gifted English-language learners (ELLs). Participants were 1,198 elementary children (approximately 40% ELLs). All were administered the Raven Standard Progressive Matrices (Raven), the Naglieri Nonverbal Ability Test (NNAT), and…

To provide a differentiated characterization of autistic children's logical deficits, a non-verbal, microanalytic method designed for infants and young children was used. Subjects were 12 autistic children ranging in age from 5 to 7 years and a control group of 12 normal children ranging in age from 23 to 30 months. Subjects were given two…

Regression analysis revealed that a reliable estimate of the field-analytic disposition could be derived from a composition of scores on the Gottscaldt, Space Relations, Street Gestalt, and Perceptual Acuity tests. (Author)

Examines the order of emergence of the concepts "in,""on," and "under" in a nonverbal cognitive task and in linguistic comprehension and production tasks. Subjects were 75 Israeli children between 14 and 30 months of age. In general, cognitive tasks were solved first, language comprehension tasks second, and language…

Evaluated the receptive vocabulary ability and nonverbal cognitive ability of 20 Spanish-speaking and 11 bilingual Mexican-American preschool children. The children obtained significantly lower scores on the Peabody Picture Vocabulary Test-Revised than on the Perceptual Performance Scale of the McCarthy Scales of Children's Abilities. Bilingual…

Fifty hearing-impaired elementary-school students completed the Kaufman-Assessment Battery for Children; scores correlated highly with scores from the Wechsler Intelligence Scale for Children-Revised and with school achievement. The Simultaneous Processing Scale and the Nonverbal Scale seemed appropriate for hearing-impaired children while the…
