Answer:
Proactive interference is the interference effect of previously learned materials on the acquisition and retrieval of newer material.
Example of proactive interference:
remembering a friend's new phone number after having a previously learned their old number
Retroactive interference is when more recent information gets in the way of trying to recall older information
Example of retroactive interference:
calling your ex- boyfriend/girlfriend by your new boyfriend/girlfriend's name.
