Forced-choice paradigms hide the signal in a randomly chosen interval
Evidence
In a forced-choice paradigm, at least two, but sometimes more, observation intervals are presented. Only one randomly chosen interval contains the signal (the signal-present interval); all other intervals do not (the signal-absent intervals). Listeners select which interval contains the signal, and they will be either correct or incorrect. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 316
