On Sampling Statistics In Observer Performance Studies
Arthur E. Burgess · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1989
Studies of human and ideal observer decision performance are designed to estimate a measure of observer performance (e.g. efficiency or d'). The experimenter would like to use a relatively small number of images or decision trials because of a variety of constraints (observer time, image preparation time etc.). Sampling variance results will be presented and experimental strategies for both ROC and Forced Choice studies will be analyzed and discussed. In many situations ROC rating scale experiments are the most economical.
