This paper discusses how a seldom-used statistical procedure, recursive regression (RR), can numerically and graphically illustrate data-driven nonlinear relationships and interaction of variables. This routine falls into the family of exploratory techniques, yet a few interesting features make it a valuable compliment to factor analysis and…

The objective of this study was to identify those cognitive characteristics that best differentiate the Navy's Basic Electricity and Electronics (BE/E) Preparatory School graduates and failures. Subjects included 207 BE/E students--172 graduates and 35 failures. Before these trainees had commenced BE/E School, they were administered six tests of…

A U.S. Air Force study was designed to investigate simultaneously four cognitive styles--field dependence-independence, reflectivity-impulsivity, leveling-sharpening, and visual-haptics. A sample of 206 undergraduate volunteers at the University of Oklahoma were tested with the Successive Perceptual Test I (SPT-I), the Hidden Figures Test (HFT),…

The mechanisms of perceptual learning are analyzed theoretically, probed in an orientation-discrimination experiment involving a novel nonstationary context manipulation, and instantiated in a detailed computational model. Two hypotheses are examined: modification of early cortical representations versus task-specific selective reweighting.…

The roles of cognitive, perceptual, visual-motor, behavioral, achievement, and demographic factors in nonpromotion at kindergarten were examined for 34 nonpromoted and 34 promoted kindergarten children. Retained children were more likely to be young, male, and of lower socioeconomic status. Implications for interventions to assist retained…
