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…

Three studies examine the validity of the Preschool Form of the Cognitive Abilities Scale--Second Edition (CAS-2). Significant high concurrent criterion-related validity correlations, corrected for restricted range, are found between the CAS-2 and the Detroit Test of Learning Ability--Primary: Third Edition for 26 three-year-olds (r[subscript c] =…

Research in this effort attempted to review evidence of the construct validity of certain measures of intellectual potential for Canadian native pupils, and to examine the relative predictive validity, over a four-year period, of several measures of general intellectual ability for a sample of Metis pupils at Faust, Alberta, and 2 samples of…

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)

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)

Over one thousand British primary schoolchildren completed the Crandall Intellectual Achievement Responsibility Questionnaire. Comparisons with earlier American data provided similar results. The Crandall scale is more closely related to attainment than to intelligence, indicating that high internalized reinforcement responsibility provides a…

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)

This collection of papers, concerned with the nature and theory of intelligence, forms part of a project to integrate test and factor theory with the empirical, functional relationships involving standard intelligence tests. The project will render more objective the use of factor analysis in personnel research. A definition of intelligence…

The scientific concept of intelligence has been heavily influenced by the technology of measurement. The variables which can be measured have been made the operational definition of intelligence. This approach differs from a deductive approach, in which a theory of cognition in general is used to derive the sorts of measurements that must be taken…

This study investigated the differential validity of the Wide Range Intelligence Test, which is a new, brief measure of ability. Participants (N = 744) ranged in age from 5 through 85 years (M = 26.7 years, SD = 21.4 years) and varied by the demographic variables of gender, race/ethnicity (Anglo, African American, Hispanic), and education level…
