I need to write a literature review. the question is “What are the effects of stereotyping and ad-repetition in the advertising industry towards consumer?”

the assignment is to do a literature review on the question: What are the effects of stereotyping and ad-repetition in the advertising industry towards consumer?
the word count is 500, can be more but not more than 600

I prefer  most of the references are from e-journals, e-book  or websites. since I don’t have access to hard books.

In the file I dropped below there are some that I have done, but I’m not sure about it.
