Successive retrieval from permanent storage

Abstract

Two separate, spontaneous retrievals without prior presentation of items from each of two categories in three sequences (AABB, ABAB, or ABBA) demonstrated item-specific facilitation of second retrieval that was the same irrespective of sequence. Twice as many new items were gained, mostly at the end of second retrieval, as were lost from first retrieval. About 85% of infrequent, as well as more frequent, items from throughout first retrieval were recalled again in second retrieval. These items were recalled mostly at the beginning of second retrieval, when retrieval rate was increased.
