Answer:
a. the self-reference effect.
Step-by-step explanation:
This strategy suggests reliance on the self-reference effect. The way Jeannie is storing this new information to the previous ballet information she had is called self-reference. She has efficiently encoded the new stimulus to remember it. She has related the new memories with her previous knowledge of ballet and her affection for dancing. This leads to a better retrieval of the memories. Human beings tend to better remember things that are related to the self.
