When will the most complete recovery of memory typically occur after a critical incident?

The most complete recovery of memory after a critical incident is typically expected to occur after the second sleep period. This is because sleep plays a significant role in memory consolidation, allowing the brain to process and integrate experiences. During the first sleep period, initial memories can begin to stabilize, but it is during a subsequent sleep period that deeper processing occurs, leading to a more comprehensive retrieval and organization of memories related to the incident.

After the first debriefing, while some information might be recalled and discussed, it does not equate to the brain's full recovery capacity. Similarly, after the first sleep period, memory may still be fragmented, and some details may not yet have been fully consolidated. The final report, although it summarizes the incident, does not directly relate to the natural cognitive processing that occurs through sleep. Therefore, the second sleep period is crucial for achieving a more complete recovery of memory relating to the incident.
