Document Summary
Limbic system (and olfaction) strong emotions make for stronger memories some stress hormones boost learning and retention. Just know hippocampus is important for long term memories. This has implications for ptsd and memory for other stressful events such as "flashbulb memories" like when 911 happened. Sleep and dreaming is a time when our memories get improved - mental housekeeping. Recent study shows the reversal of memory loss due to sleep deprivation. Why we forget: forgetting curve: decay: initially thought that memory fades in time, now is thought that with sleep there is interference & inhibition. Proactive interference occurs when first learned items reduce the recall of more recently learned items. (older interferes with newer). Retroactive interference - occurs when newer items reduce recall of older items. Recently learned stops previous items: encoding specificity. Context dependent memory - where memory is tied or linked to the place or situation in which it was encoded.
