Answer:
retrieval practice effect and retrieval-induced forgetting
Explanation:
Retrieval practice effect, known also as the testing effect, is the technique of retention of information and retrieving a piece of information that should be long term. Repeating the information fro the memory ensures it is staying in the memory for a longer time, making it possible to retrieve again while also boosting the learning process.
However, this process can sometimes backfire and cause phenomenon retrieval-induced forgetting (RIF). Noted for the first time 1994, retrieval-induced forgetting is a consequence of retrieval of information through conscious remembering. It is not yet certain why and how this happens, does this process inhibits the memory or interfaces with the existing information.
