Many Flynn effect (FE) studies compare scores across different editions of Wechsler's IQ tests. When construct changes are introduced by the test developers in the new edition, however, the presumed generational effects are difficult to untangle from changes due to test content. To remove this confound, we use the same edition of Wechsler…

We used two studies to evaluate, modify, and provide initial validation for a revised Academic Hardiness scale. First, 16 experts rated scale items for content validity and identified two problematic questions. Second, confirmatory factor analyses with 300 Grade 10 students (46% boys, age range 14-17) identified a 17-item version to be the best…

Background: Sentence construction and syntactic organization are known to be poor in children with specific language impairments (SLI), but little is known about the way in which children with SLI approach language tasks, and static standardized tests contribute little to the differentiation of skills within the population of children with…

The Raven's Standard Progressive Matrices (RSPM) is a 60-item test for measuring abstract reasoning, considered a nonverbal estimate of fluid intelligence, and often included in clinical assessment batteries and research on patients with cognitive deficits. The goal was to develop and apply a predictive model approach to reduce the number of items…

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…

This paper presents a systematic review of published data on the performance of sub-Saharan Africans on Raven's Progressive Matrices. The specific goals were to estimate the average level of performance, to study the Flynn Effect in African samples, and to examine the psychometric meaning of Raven's test scores as measures of general intelligence.…

Investigation of criterion-related validity of test scores of 107 deaf residential adolescents found concurrent validity between the Standard Progressive Matrices (SPM) and the Performance IQ of the Wechsler Intelligence Scale for Children-Revised, using both hearing and deaf norms. Predictive validity was supported by correlations between the SPM…

The scores of 537 14-year-old students in Nigeria on the Raven Progressive Matrices were correlated with their scores on an achievement test, to provide an estimate of the predictive validity of the Raven. Results indicated low validity for this usage. (Author/JKS)

One hundred culturally disadvantaged children were tested on culture-fair (Raven) and culturally biased (WISC) tests, and scores were correlated with academic achievement. (Author)

This study was undertaken to shed light on problems concerning the construction and use of a common test battery for various South African population groups. Specifically, the psychometric suitability for use with Indian and Black pupils, of the Junior Aptitude Tests (JAT), which were standardized for White pupils in Standard 7 was studied. The…

The power of the Slingerland Screening Tests was examined, and a discrepant performance index was developed between cognitive measures to predict early school achievement and class placement for children at risk for specific language disabilities. Subjects were two successive cohorts of entering kindergarten children for whom Slingerland Tests…

Author focused on differences between whites and negroes in the United States and more generally on racial variation in man. (Author/RK)

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 PREDICTIVE ABILITY OF TWO INTELLIGENCE TESTS ON A CROSS-CULTURAL SAMPLE WAS STUDIED. THE STANDARD PROGRESSIVE MATRICES AND THE D. 48 TEST WERE ADMINISTERED TO 1,579 GIRLS IN GRADES 9 THROUGH 12. OTHER TEST SCORES WERE OBTAINED FROM STUDENT RECORDS. THE CROSS-CULTURAL GROUPS CONSISTED OF (1) INDO-EUROPEAN, (2) SPANISH-AMERICAN, (3) NEGRO, AND…

The predictive validity of the Standard Progressive Matrices (SPM) was examined with a sample of 212 sixth-grade students and 214 seventh-grade students. Correlation coefficients between the SPM and the California Achievement Tests of Reading, Language, and Mathematics ranged from .34 to .60. (Author/LMO)
