Answer: This is an example of transience memory
Step-by-step explanation:
What is a transience memory ?
The memory that we have stored tends to depreciate or disappears slowly over time and this is referred to as transience.
Usually this occurs as we become older or when our hippocampus is damaged which is a part of our brain responsible for retaining memory or transferring memory from short term to long term memory .
It also happens because we may no longer need to use that kind of information stored in our long term memory such as Giorgio above had studied a poem for the purpose of reciting it but after reciting he had no purpose of that information so it disappears over time.
