The interpretation of subtest profiles from intelligence testing remains popular among many practitioners who use subtest performance to draw diagnostic conclusions, in spite of criticism by some researchers, who point to the low reliability and predictive validity of subtest scores in predicting achievement outcomes. Prior research outlines two…

Schools often administer brief intelligence tests as the first step in the identification of students who are cognitively gifted. However, brief measures are often used without consideration of underlying constructs or the psychometric properties of the measures and without regard to the links between screening decisions and educational…

The authors argue that upon publication of a paper, the data should be made available through online archives or repositories. Reasons for not sharing data are discussed and contrasted with advantages of sharing, which include abiding by the scientific principle of openness, keeping the data for posterity, increasing one's impact, facilitation of…

The literature pertaining to intelligence assessment reveals an ongoing discussion about the areas of intelligence captured by nonverbal tests. To date, few studies have investigated the criterion validity of the Test of Nonverbal Intelligence, Third Edition (TONI-3). The present study investigates the concurrent validity of the TONI-3 in a sample…

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.…

This article outlines shortcomings of currently used university admissions tests and discusses ways in which they could potentially be improved, summarizing two projects designed to enhance college and university admissions. The projects were inspired by the augmented theory of successful intelligence, according to which successful intelligence…

Considerable debate exists regarding the accuracy of intelligence tests with members of different groups. This study investigated differential predictive validity of the "Wechsler Intelligence Scale for Children-Fourth Edition". Participants from the WISC-IV--WIAT-II standardization linking sample (N = 550) ranged in age from 6 through…

This research examined whether the SAT and ACT would predict college grade point average (GPA) after removing g from the tests. SAT and ACT scores and freshman GPAs were obtained from a university sample (N=161) and the 1997 National Longitudinal Study of Youth (N=8984). Structural equation modeling was used to examine relationships among g, GPA,…

Industrially advanced societies increasingly encourage the skills of bureaucrats and technicians rather than the creative ones--because their universities admit students on the basis of intelligence-test scores and secondary school grades, two measures which have practically no correlation with real-life creativity."

This research indicates that the Ertl Neural Efficiency Analyzer is not yet out of the developmental stage. (IRT)

The current study examines the views of experts in the science of mental abilities about the primacy and uniqueness of "g" and the social implications of ability testing, and compares their responses to the views of a group of non-expert psychologists. Results indicate expert consensus that "g" is an important, non-trivial determinant (or at least…

The predictive power of various cognitive skills at three months of age in terms of later cognitive functioning was examined. Visual habituation and recovery predicted later intellectual functioning at 24 months better than global intelligence or object permanence scores. Changes in cognitive functioning may be a transformation of skills.…

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)

Examined 128 children for contributions of biomedical risk conditions, SES, and HOME scores to prediction of intelligence, and association of extreme scores on HOME and SES to intelligence-test performance. Found home environment was the most important predictor of intelligence at all ages, with SES showing a smaller effect beginning at age 5.…

The relationship between elementary school children's mental ability scores and classroom performance was investigated. A strong predictive relationship between mental ability scores and classroom performance was obtained irrespective of the subjects' socioeconomic status. These findings indicate that predictions of academic performance derived…
