Abstract:

The relationship of signal identification to signal detection was examined in a series of experiments. The signals were idealized lines and patterns of lines in a spectrographic display. On each trial, progressively more of the complete spectrogram was exposed in successive observation intervals, and the observer made both detection and identification responses after each interval that were based on the accumulating evidence. One model employed conceives of detection and identification as proceeding together over time as parts of a unified process. A second model employed shows how the joint detection-and-identification ROC--a Relative Operating Characteristic that relates the joint probability of correct detection and correct identification to the probability of a false detection--may be predicted from the simple detection ROC. Both models were supported by the data. Author
