The purpose of this study was to determine whether the Index of Coordination (IdC) and the propulsive phase durations can differentiate performance level during a maximal 400-m front crawl swim trial. Sixteen male swimmers constituted two groups based on performance level (G1: experts; G2: recreational). All participants swam the 400-m front crawl…

Responds to McNeil's proposal for assessing teacher competency, arguing that the technique (1) is unrepresentative of a teacher's behavior, (2) uses inappropriate statistical techniques, and (3) is punative rather than diagnostic. (VJ)

This review is one in a series intended to develop methods which maximize the use of the existing scientific literature as a basis for predicting human performance. It is concerned with sensory performance in target detection, defined in terms of the "probability of detection" of a flash of light. Two conditions of detection are…

It has long been assumed that Part 3 of the National Boards, which stresses patient management and clinical problems, is a valid measure of "clinical competence" for doctors. These authors, challenging this premise, devised a study to analyze which components of medical school achievement are most predictive of Part 3 performance. Their…

The longitudinal interrelations among age, visual and auditory short-term memory, and the concrete operational tasks of class inclusion and combinatorial reasoning were investigated over four testing occasions in a sample of 134 students, initially ranging from 5 to 12 years in age. The Piagetian task battery involved placement of colored…
