Which process explains why older memories may be harder to access after learning new information?

Storage refers to the process of maintaining information in the brain over time. While storage is essential for memory retention, it does not directly explain the difficulty in accessing older memories after learning new information. The issue lies not in the storage of memories but in the interference that occurs when trying to retrieve them.

Encoding is the initial step of converting information into a format that can be stored in the brain. Although effective encoding is crucial for memory formation, it does not account for the retrieval difficulties faced with older memories after learning new information. The retrieval process, affected by interference, is what leads to these challenges.

Retrieval is the process of accessing stored information when needed. While retrieval issues can arise, the specific reason older memories may become harder to access after new learning is primarily due to interference, not the retrieval process itself. Retrieval can be successful; however, interference complicates this process.
