Proactive v. Retroactive Interferece

Proactive interference occurs when older memories interfere with the retrieval of newer information. For example, if you learned to play basketball and then later try to learn football, the skills and strategies from basketball might hinder your ability to pick up football techniques.

On the other hand, retroactive interference happens when new memories interfere with the recall of older information. For instance, if you learn a new phone number, it might make it difficult to remember an old one.

In summary, proactive interference focuses on old memories affecting new learning, while retroactive interference deals with new information impacting the recall of older memories.
