Answer: Transience
Step-by-step explanation:
Transience refers to the general degradation of a specific memory over a period of time. The events that can be remembered are the recent events than those of the events that has occurred in the past.

Transience is caused because of the interference in the brain. One that does not allows the brain to retain the older information over new ones known as retroactive interference and the other is proactive interference where the older information does not allows the new information to be retained by the brain.
