What is proactive interference?

Proactive interference occurs when previously learned information interferes with the ability to learn new information. This type of interference happens when old memories disrupt the encoding or retrieval of new memories. For example, if someone learns a new set of directions to a friend's house, but then tries to remember an older set of directions to the same place, proactive interference may occur.

Proactive interference is often more pronounced when the old information is similar to the new information, making it harder to distinguish between the two. This can result in errors in memory recall, confusion, and difficulty learning new material.

This phenomenon is commonly studied in the field of psychology and cognitive science, as it provides insights into how memory works and how information is stored and retrieved in the brain. Researchers have identified strategies for minimizing proactive interference, such as spacing out learning sessions, using mnemonic devices, and practicing retrieval of information over time.
