Forced-choice procedures typically provide post-trial feedback on the correct answer
Evidence
Two-Interval Forced Choice. In this procedure, the subject is presented with two intervals, and has to decide whether the signal occurs in the first or second interval. Sometimes three or four intervals may be used and the task of the subject is to decide in which interval the sound is different with respect to some quality, say loudness or pitch. With these procedures, feedback is frequently given. This means that after each trial the subject is informed of the right answer, usually by a light indicating the interval that contained the signal. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.
