Katie H- does hindsight taint memories?

does hindsight taint memories? 

 Dr. Redick spoke in class about our processing of memories and how when we recall memories it changes them. this is consistent with the currently accepted theories of memory in psychology.  Every time you remember an event from the past, your brain networks change in ways that can alter the later recall of the event. we have also all probably experienced it. Imagine you are telling your friends a story about a terrible mistake you made. It could be locking your keys in your car, going on a date with a bad person, or taking a job you weren't suited for. during the telling of the story, you probably either said or thought to yourself "I should've know at that point that this was a bad idea". that is the magic of hindsight. then the next time someone asks you about it, that statement gets ingrained in your memory and it is repeated next time you tell it. if you repeat this over time, it could change the story so much that it becomes "I knew I had messed up at this point" which implies you knew it was a bad idea at the time. but you believe that you really did feel this way. any kind of recollection of a memory is going to change the memory at least slightly, which is why repeated recollection and telling of things alters the memory to where people who all experienced the same thing 10 years go have very different memories of what happened. is it also important to note here that your memory does not save all the information you take it, only enough context clues for your imagination to fill in the rest. if something wasn't significant to you or fit your schema of something, you will not remember it. for example, if you are sent into a room to retrieve something, you will most likely only remember the thing you were meant to get as something that was in the room.
