What is one method to eliminate long-term memories during an experiment?

Learning interfering material is considered an effective method to eliminate long-term memories during an experiment. This approach is based on the concept of retroactive interference, where new information introduced can disrupt or overwrite previously stored memories. When participants learn new material that is similar to or related to the original memory, it can lead to confusion and make it difficult to recall the original information accurately.

This technique is often utilized in cognitive psychology experiments to study how memories can be modified or erased through subsequent learning. By introducing competing information, researchers can observe how well the original memory is retained and assess the extent to which new learning impacts it. This understanding has significant implications for memory theories and can provide insights into how memories are structured and accessed within the brain.
