Final answer:
Retroactive interference involves difficulty in recalling old information due to newly learned information, in contrast to proactive interference where old information obstructs the rememberance of new information. These phenomena impact the retrieval of long-term memories and can affect relearning experiences.
Step-by-step explanation:
Along with unlearning, there is also retroactive interference involved in forgetting. Retroactive interference occurs when newly learned information impedes the recall of older information. For instance, learning new contact details can make it more difficult to remember previous ones. This is not to be confused with proactive interference, in which old information hinders the recall of newly learned information. Both types of interference affect our ability to retrieve information from long-term memory.
It is not only about forgetting but also about the capability to relearn. While older memories can be obscured, the foundation they created can often lead to quicker relearning of the information. Understanding these memory processes can be beneficial in improving our study and recall strategies.
