Reasons we forget
Encoding Failure – we didn’t pay attention or rehearse it.
Storage Failure – memories that aren’t rehearsed are lost
Ebinghaus curve – over 50% of what we learn is quickly forgotten (if not rehearsed), but the remainder sticks for a long time.
Retrieval Failure – an inability to “locate” memories. Creates a “tip of the tongue” phenomenon.
Proactive interference – (“forward-acting”) when old memories interferes with new memories.
Retroactive interference – (“backward-acting”) when new memories interfere with old memories.
Repression (motivated forgetting) – forgetting things we don’t want to remember.
Misinformation effect – we tend to incorporate misleading information into our memories.
Source Amnesia – misattributing the source of information
We create false memories, too (memory construction)
