London remembers a time when she was young when she got lost in a department store and couldn’t find her mom. when talking to her family about it, they corrected her memory and said that it was actually her sister who was lost, and that she had just been present. over time, the source of her original memory became confused. this is an example of

Misattribution.

Explanation:

Misattribution is the attribution of memories to incorrect sources or believing that you have seen or heard something you haven't. It refers to the ability to remember information correctly, but with incorrect recollection of the source of that information. It is attributing memories to things that never happened, that you didn't see or hear, or that you believe you witnessed but did not. Sometimes misattribution leads a person to "recall" something that in fact never occurred. In other cases, misattribution can cause someone to take the information they currently have and believe that they gained that information in a way other than what happened.
