Answer:Proactive interference
Explanation:Proactive interference refers to how past memories hinders your ability to acquire new memories.
This occurs mostly when there is a competition between the old and new information , meaning there are some similarities between this information.
For example it is hard to recall your friend's new number because you are used to their old number.
Retroactive interference on the other side is when you find it hard to retrieve old infomation due to neq memories.
