Answer:
The correct answer is retrieval practice effect; retrieval-induced forgetting
Explanation: The first answer is retrieval practice effect which when explained further simply means tying to memorize information without having it in front of you. For instance, suppose you are trying to memorize a passage in your favorite book, you can do retrieval practice by trying to say words in the passage from your memory, that is without looking at the actual passage.
The second answer is retrieval-induced forgetting. This phenomenon results from an act of remembering but also causing the memory to forget similar information it would have retained before. However, this might just be a temporary forgetfulness. For example when one is trying to remember a specific word, other words that are closely related to that specific word compete in the mind and might result in one not being able to retrieve the specific word immediately.
