This study uses a novel framework based on work by Shipstead, Harrison, and Engle (2016) that includes measures of both working memory capacity and fluid intelligence in an attempt to better understand the processes that influence successful reading comprehension at the latent level. Further, we extend this framework to a second educationally…

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…

Reviews findings on the predictive validity of psychometric tests of intelligence. Concludes that conventional tests of intelligence can be useful but only if they are interpreted very carefully, taking into account the factors that can affect them, and in conjunction with other measures. (Author)

Genetic influence was estimated on Wechsler Intelligence Scale for Children subtests from inbreeding depression scores calculated on cousin marriages in Japan (n=1,854 children) and correlated with American Black-White racial differences. The genetic contribution of racial differences in cognitive performance may be more robust than was previously…

Explores the use of common sense testing and measurement as a means of predicting real-world performance. The authors discuss practical versus book knowledge, examine several empirical studies of practical intelligence, describe tacit knowledge and the instruments used for testing it, and present findings from a tacit knowledge research program.…

Raven's Progressive Matrices test items were analyzed for M demand (Pascual-Leone's developmental construct). Data on second- and third-grade subjects were analyzed for extent of absolute agreement of Raven and Figural Intersection Test (FIT) scores. Raw scores on the Raven could be deduced on the basis of FIT performance. (Author/RD)

This study sought to determine the appropriateness of two conventional intelligence tests for assessing the ability of economically deprived young adults participating in job training programs by comparing their test results with those of the test standardization groups. The Wechsler Adult Intelligence Scale (WAIS), and the Langmuir Oral Direction…

Student and test characteristics were examined by multiple regression analysis and discriminant function analysis to explain why 171 political science undergraduates scored differently on essay versus objective final examinations. Student characteristics included: (1) patterns of creative, crystallized, and fluid abilities as measured by the…

To clarify the relationships between reaction time (RT) variability and intelligence, RT distributions from 303 male Navy recruits were partitioned into 16 fast-to-slow latency bands calculated with measures of mental ability. The slowest bands (worst trials) were the best predictors of intelligence and working memory performance. (SLD)

The results of this study indicate that the WISC-R IQs are good predictors of achievement. They predict general achievement as represented by the PIAT total score and achievement in specific areas including reading recognition, mathematics, and spelling as measured by the PIAT. (Author)

Two successive recall tasks and eight ability measures were presented to women of five age groups to investigate the changing relation between performance and ability measures at various stages of the learning process during adulthood. (MS)

The article describes a kind of intelligence testing which assumes that the potential of a "retarded performer" may be greater than his demonstrated knowledge, and therefore tests him in the process of learning. (CD)

The effectiveness of a measure of the processing capacity of working memory, called the reading span test, is demonstrated in predicting performance and understanding individual differences in reading comprehension. (Author/PN)

Sources of continuity among nine measures of infant cognitive processing and later childhood intelligence quotient were examined through developmental structural equation models applied to a sample of 208 twin pairs measured from 7 to 36 months. Skills assessed appear related to general cognitive ability in a relatively unstable manner. (SLD)
