Short-Term Forgetting of Order under Conditions of Reduced Interference

Abstract

Three experiments examined the short-term retention of order in a modified Brown-Peterson task. Our intent was to examine the loss of order memory, unconfounded by item memory, under conditions in which interference from prior trials is kept low. In previous work on the short-term forgetting of order, experimenters have tended to repeat the same items across trials or to draw from a restricted set; in our experiments, we changed the to-be-recalled items from trial to trial and used reconstruction as the retention measure. In all three experiments, very little forgetting was obtained across retention intervals that have traditionally produced dramatic and systematic loss. Our results are reminiscent of those obtained in the Brown Peterson task when performance is assessed after only the first experimental trial.
