I am particularly pleased to discuss the application in psychophysics of the general theory of signal detection at a symposium commemorating Fechner’s founding work. Although this effort is in part a theoretical and experimental critique of Fechner’s principal concepts and methods, which indicates that they should be replaced, I suspect that hewould have welcomed it warmly---in fact, that he would have been among the first to recognize the value of these new tools had they become available in his time. I suspect this on the basis of his interest in Bernoulli’s early ideas about statistical decision ([3], p. 284), and in the notion of subthreshold, or "negative," sensations ([3], p. 293)--two central concepts in the psychophysical application of the theory of signal detectability.
