Answer:
True.
Explanation:
The interference theory explains the memory of the human brain. These memories are long term memories. Two main types of interference are proactive interference and retroactive interference.
The retroactive interference means when the older memories vanishes due to the learning of the new memory. The previously learned memories are forgotten by the individual. The same thing has happened with Mimi as she forgot the previous recipe due to the new memory.
