Visuo-spatial reasoning tests, such as Raven's matrices, Cattell's culture-fair test, or various subtests of the Wechsler scales, are frequently used to estimate intelligence scores in the context of inter-racial comparisons. This has led to several high-profile works claiming that certain ethnic groups have lower intelligence than others,…

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…

This paper examines students' performance in Non-verbal Intelligence tests relative academic achievement of some selected secondary school students. Two hypotheses were formulated with a view to generating data for the ease of analyses. Two non-verbal intelligent tests viz: Raven's Standard Progressive Matrices (SPM) and AH[subscript 4] Part II…

Many studies have demonstrated that listeners use information extracted from verbs to guide anticipatory eye movements to objects in the visual context that satisfy the selection restrictions of the verb. An important question is what underlies such verb-mediated anticipatory eye gaze. Based on empirical and theoretical suggestions, we…

Normative data for 8-15 year olds for the Standard Progressive Matrices in Saudi Arabia were obtained in 1977 and 2010. The 2010 sample obtained higher average scores than the 1977 sample by 0.78d, equivalent to 11.7 IQ points. This represents a gain of 3.55 IQ points a decade over the 33 year period. (Contains 1 table.)

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…

The concurrent and predictive validities of the Naglieri Nonverbal Ability Test (NNAT) and Raven's Colored Progressive Matrices (CPM) were investigated in a large group of Italian third-and fifth-grade students with different sociocultural levels evaluated at the beginning and end of the school year. CPM and NNAT scores were related to math and…

The paper describes a cross-cultural and historical meta-analysis of Raven's Progressive Matrices. Data were analyzed of 798 samples from 45 countries (N = 244,316), which were published between 1944 and 2003. Country-level indicators of educational permeation (which involves a broad set of interrelated educational input and output factors that…

Recently this journal published a research article examining the effectiveness of three different tests in identifying ethnically diverse gifted and talented children (Lewis, DeCamp-Fritson, Ramage, McFarland, & Archwamety, 2007, Volume 15, Number 1, pp. 38-42). After examining the proportions of Caucasian and non-Caucasian children identified…

Just as the Raven Progressive Matrices Test was uncorrelated in this sample with other measures of intelligence so was it much less well predicted from several information processing measures. It was found that verbal performance, indicated by a vocabulary score, was highly predictable from measures of information processing. While preserving…

The feasibility of administering some tests directly under computer management was investigated with Raven's Progressive Matrices Test (RPMT), a nonverbal test of general aptitude, chosen as the instrument for the study. Subjects were 76 deaf students in a vocationally-oriented postsecondary educational program. Half of the subjects were tested…

When administered to 125 deaf youngsters, ages 5-12, the WISC performance test had good reliability and predictive validity, but administration to some young or physically handicapped children proved difficult. The Colored Progressive Matrices proved satisfactory with older subjects, but its suitability for younger deaf children was not confirmed.…

The purpose of this study was to compare the effectiveness of the Raven's Standard Progressive Matrices, the Naglieri Nonverbal Abilities Test (NNAT), and the Iowa Test of Basic Skills (ITBS) in selecting for ethnically diverse students who may be gifted. The participants of the study were 175 students enrolled in Grades 3-5 and Grade 8 in a…

A study of the responses made to problems selected from Raven's Progressive Matrices showed differences in the kinds of errors typically made by eighteen-year-old students. Nine problems were used and the 68 subjects were told to draw their answers on the answer sheets. There were two trials per puzzle. A classification system, devised for errors,…

Investigated the internal consistency reliability estimates of the Raven Coloured Progressive Matrices (CPM) for 96 Anglo and Mexican American third-grade boys from low socioeconomic status background. The results showed that the reliability estimates of the CPM for the two ethnic groups were acceptably high and extremely similar in magnitude.…
