TPYPES OF INTERFERENCE:
PRO-ACTIVE INTERFERENCE= when OLD/existing memories affect NEW memories i.e. interference goes forward
OLD INO========> NEW INFO
RETRO ACTIVE INTERFERENCE= when new memories affect old/existing memories i.e. intererence goes backwards.
NEW INFO=======> OLD INFO
KEY STUDY INTERFERENCE
