Proactive Interference | AI Learning Guide

Proactive interference is when old information blocks the recall of new information. Think of learning Italian after Spanish: the Spanish word for bread keeps popping up instead of the Italian one. This happens because the old memory is stronger and more established, so it competes with the new one during recall. Understanding this helps you see why switching between similar subjects can be tricky.

Definition

Proactive interference happens when previously learned information interferes with the ability to learn or recall new information. The old memory 'moves forward' to disrupt the new one.

Study Example

You learned Spanish in high school. Now you're learning Italian. When trying to recall the Italian word for 'bread' (pane), you keep thinking of the Spanish word 'pan'. The old Spanish knowledge proactively interferes with your new Italian recall.

Proactive vs. Retroactive

Proactive interference involves old memories disrupting new ones, while retroactive interference involves new memories disrupting old ones.

Proactive

Old interferes with new
Example: Spanish blocks Italian

Retroactive

New interferes with old
Example: Italian blocks Spanish
