The effect of perceptual speed on performance and paper-and-pencil measures of spatial ability is examined. Perceptual speed is defined as speed in comparing figures or symbols, scanning to find figures or symbols, or carrying out other very simple tasks involving visual perception. It was hypothesized that perceptual speed would have more…

The generality of ability factor structure in adulthood and old age was investigated. Data were analyzed for 198 young individuals (15-32 years), 156 younger old individuals (53-68 years), and 156 older old individuals (69-91). Variables were nine tests marking three ability factors. (Author/CTM)

The Educational Testing Service Kit of Factor-Referenced Cognitive Tests contains 72 tests that are supposed to be markers of 23 latent cognitive constructs. Examination of the factor structure of four of these tests with 165 undergraduates suggests caution in using the measures as markers of distinct factors. (SLD)

The Wechsler Adult Intelligence Scale (WAIS) and 20 tests from the French Kit were administered to over 100 undergraduates. Analyses revealed ten factors: verbal comprehension, visualization, memory span, syllogistic reasoning, general reasoning, induction, mechanical knowledge, number facility, spatial orientation, and associative memory.…

The primary objectives of this project commonly refereed to as "Assessing Human Abilities" were: (1) to provide reference measures for cognitive factors; and (2) to provide a guide to reference measures for self-report temperament factors. The overall objective was to conduct research in the area of factor analysis directed toward the…

This report is part of a general study of Reference Measures for Cognitive and Noncognitive Factors. The main activity being reported is the development of "factor-referenced" or "marker" tests for several recently identified cognitive factors. A secondary activity involves the study of possible relationships to factors already…

Bloom's taxonomy of the cognitive domain consists of six major levels: Knowledge, Comprehension, Application, Analysis, Synthesis, and Evaluation. The purpose of this study is to construct a quantitative causal model for a set of tests designed to operationally define these six levels in order to further explore the validity of the cumulative…

This summarizes a study designed to provide a basis for researchers who study measurable areas of human performance or attempt to conceptualize and develop a theory and structure of abilities. Specifically, this study was directed toward the identification of tests that can serve as markers for well established cognitive factors. (Author/CTM)
