|  | This is similar to
  the slide for retroactive interference. The foreign language example can be
  used to demonstrate both retroactive and proactive interference, depending
  upon how you present it. Thus, examples of both are included. However, I
  generally only present only one of the two examples to avoid confusion for
  the students. For instance, I'll use the foreign language example for
  retroactive interference and the parking lot example for proactive
  interference.
