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 established. These developmental activities include a field study of these measures for improvement of the items in the tests, the determination of the reliabilities of the tests, and some clarification of these cognitive factors. The five newly identified factors are: concept attainment, figural fluency, integrative processes, visual memory, and verbal closure. Because it seemed especially important to determine whether the new factors could be separated from other somewhat similar factors, marker tests for six other factors were included in the study. These established factors are figural adaptive flexibility, logical reasoning, general reasoning, number facility, spatial orientation, and speed of closure. The results indicated that the attempt to find the verbal closure and figural fluency factors had been successful, that the visual memory factor had been adequately replicated, that there was confusion between the integrative processes factor and some of the reasoning factors, and that the attempt to replicate the concept attainment factor had failed.
