Waneta says, “I like my new school so much better that I can hardly remember what my old school was like. The names and faces from my old life are just a blur.” What would a psychologist call this memory problem?

Retroactive interference occurs when new information makes it harder to recall older information. Waneta’s experiences at her new school are making memories of her old school blurry, so this is retroactive interference. Proactive interference is the reverse: older memories interfere with learning or recalling newer information.
