Quinton is having trouble learning Spanish because he keeps reverting back to the grammatical structures of his native English language and can only remember the English vocabulary he learned first. What kind of memory interference is Quinton displaying? Proactive interference Provocative interference Retroactive interference Verbal interference

Answer: Proactive interference

Explanation: Proactive interference is the situation where an individual is not able to retain or memorize the new memories due to the hindrance of the past memories. The past memories hold back in the mind of an individual so that new information cannot completely take place in mind.

Other options are incorrect because provocative interference is not a interference term, retroactive interference does not let an individual remember the past information due to new memories and verbal interference is type of interference that creates hindrance usually in the game field. Thus, the correct option is proactive interference.
