Age-Related Decline in Controlled Retrieval: The Role of the PFC and Sleep

Figure 2

Stages of memory retrieval leading up to a memory decision. Preretrieval processes filter out irrelevant information to constrain the memory search. A retrieval attempt is made. If preretrieval processing is insufficient, postretrieval processing is engaged to edit or elaborate on retrieved content prior to making a memory decision. Bidirectional arrows between retrieval attempt and postretrieval reflect the possibility of additional retrieval attempts prior to the memory decision.
