Abstract

An auditory detection experiment was performed with rats as subjects, and the data were analyzed with a signal detection model. Rats were run at fixed sound pressure levels, and their responses were partitioned so that operating characteristics could be constructed. Measures of detectability, (de)½, were calculated from the operating characteristics, and show that (de)½ is a function of sound pressure levels, rising as these levels rise.
