n. a technique used in experimental studies on memory and recall. During the experiment, participants are presented with a list of items, upon which they are asked to recall as many items as possible in any order - that is, either right after listening (immediate recall), or after a time delay (delayed recall) wherein a new stimulus or distractor is introduced. Created by U.S. psychologists John Brown, Lloyd Peterson, and Margarent Jean Peterson.

BROWN-PETERSON DISTRACTOR TECHNIQUE: "To check on actual memory without any rehearsal, the Brown-Peterson Distractor Technique introduces a distracting stimulus in between the testing and recalling phase."
