Describes a new 48-item self-report instrument, the Multidimensional Measure of Children's Perceptions of Control, which defines children's perceptions of control as understanding the locus of sufficient cause for success and failure. Three dimensions of third- through ninth-grade children's perceptions of control are assessed within three…

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)
