The determination of auditory thresholds in cats by an operant tracking procedure

The absolute auditory intensity threshold of the cat was determined using a two-lever operant tracking procedure. In this procedure, developed by D. S. Blough, the S responds according to whether or not the stimulus is perceived, and depending on the response, the stimulus intensity is increased or decreased. Thus, S charts his own threshold. The method, which has several advantages over other procedures, proved to be successful in this study
