The consistency by which shared abilities are assessed on three intelligence tests was investigated. Instruments under consideration include: the Wechsler Intelligence Scale for Children-Revised, the Kaufman Assessment Battery for Children, and the Stanford-Binet Intelligence Scale-Fourth Edition. A list of shared abilities and the subtests…

The general intelligence factor (g) was investigated using 170 university students across three batteries of ability measures: (1) a short-term memory battery; (2) the Multidimensional Aptitude Battery; and (3) a reaction time battery. Results support the notion of g and suggest short-term memory as an essential aspect of intelligence. (SLD)

The stability of some dimensions of ability between the ages of 12 and 15 years was investigated for 225 boys and 242 girls in Sweden. Testing in grades 6, 8, and 9 indicated high stability for the general intelligence factor and for the residual of the General Visual factor. (SLD)

Equivalence in reliability and validity across 4-point and 6-point scales was assessed by fitting different measurement models through confirmatory factor analysis of a multitrait-multimethod covariance matrix. Responses to nine Likert-type items designed to measure perceived quantitative ability, self-perceived usefulness of quantitative…

The reliability and validity of multiple-choice tests were computed as a function of the number of options per item and student ability for 435 parochial high school juniors, who were administered the Washington Pre-College Test Battery. Results suggest the efficacy of the three-option item. (SLD)
