Yes-No procedures force signal detection decisions without an unsure option

Evidence

Yes-No Procedure. In this method, the subject has to decide whether a signal was present or not. There is only one interval in which either the signal occurs or doesn’t occur. This means that this procedure is a “one intervaltwo alternative forced-choice procedure”, because the subject is not allowed to answer “I don’t know whether or not a signal was present”, but has to decide “yes” or “no”. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing. Eberhard, Psychoacoustics- Facts and Models, 115
