The main point I liked to make about Signal Detectability is that there is no such thing in the sense that a given stimulus has a given strength below which it cannot be detected. First you must define the response being controlled by the stimulus. We are really talking about changes in the likelihood of occurrence of a specified response given the presence of a certain stimulus situation. A particular change in the strength of a stimulus may increase the likelihood of one response enough for it to be emitted, while not a different response. So SDT is really about behavior under stimulus control, not just stimuli.
for my own experimental application: "Brandon, Paul K. A Signal Detection Analysis of Counting Behavior (1981). in Quantitative Analysis of Behavior vol.I, Michael Commons and John A.
