Answer:
Proactive interference.
Step-by-step explanation:
What the exercise is exemplifying about is "Proactive interference" which is, as it's name indicates, an interference of our memory. When we are looking for a particular word, moment, etc., using our memory, sometimes we find a newer memory that intereferes, that confuses us for a moment. This is what is called proactive interference, and a very good example of that is what occurs to Deanna: she studied Spanish in high school and now, probably years later, she studies French. But, when attempting to do so, she confuses some words with Spanish words.
