When You Try to Remember Your 10^th Birthday Party, You

When you try to remember your 10^th birthday party, you always picture a younger version of yourself sitting around a cake with friends. However, you've recently come across some old photos of that day which reminded you that (because of a last minute change with the day the party took place) there actually was no cake that year. It occurs to you that you probably have had cake every year since, and those more recent memories may have affected what you thought happened on your 10^th birthday. If that was the case, what principle could it demonstrate?

A) childhood amnesia
B) repression
C) proactive interference
D) motivated forgetting
E) retroactive interference
