Pcunwanted as a function of Δ/R for the three- and four-interval oddity, 3AFC, and 4AFC paradigms. Each line type corresponds to a single paradigm, as indicated in the inset legend. Pcunwanted refers to the maximal proportion of correct responses that can be achieved based on an unwanted cue, the use of which is limited by the application of a random rove drawn for a uniform (or “rectangular”) distribution with a range (or “width”) of R. Δ denotes the “size” of the unwanted cue, as defined in the text.
