To what extent is memory the content of what we recall, and to what extent the process of recollection?

So basically, I would like the essay to be as if a student wrote it ( student language, not a professional language) the most important thing here to focus about is to use normal resources that anyone can have access through, not university sources! because if you write in a way that is not so convincing as i wrote it, it will cause me a major problem.
and this is a IB (International Baccalaureate) Essay, so please please please follow the files I have uploaded.
