Operating Characteristics from Yes‐No and Forced‐Choice Procedures

摘要: Operating characteristics were obtained in yes‐no (YN) and two‐alternative forced‐choice (2AFC) experiments auditory signal detection. Four listeners used a six‐point scale of confidence ratings with each these psychophysical methods. An extreme rating (1 or 6) indicated high that the was not presented (in YN) occurred first second observation interval 2AFC). The two possible events both YN 2AFC equally likely. sinusoid 1000 cps for 0.10 sec against continuous background noise. Testing conducted at E/N0's 7.9 15.8. When plotted on double‐probability paper, linear operating provided good fits to data points from procedures. characteristics, addition, had slopes near unity. theory detectability (TSD) correctly predicts unit slope character...
