Document Summary

Rapidly lost unless we actively do something with it. Decay material gets old fades away over time. Interference new material pushes old out. Had people learn a list of words until 100% accurate. Now have them recall immediately or 1-8 hours after. Whether or not people were doing it while awake or sleep and then recall the list. Awake recall rate gets close to zero at 8 hours after (decay) Asleep recall rates remain near 80% even 8 hours after (interference: acoustic coding coded by sound when transferred into short term memory translates into sound. Words that sound the same will interfere with a list of words being remembered and possibly cancel them out (ex. Prefrontal cortex when damaged can not recall anything. Semantic coding store associated on meaning not sounds. Words that mean the same as the words you need to remember will interfere (ex. Consolidation ltp (long term potentiation) move things from hippocampus into long term memory.
