Dissertation Topic Research articles and methods

You will need to bring up 4 other articles, and review and answer the questions in instructions for all 5 about how their methods align and how they are conducting and proof of study, and how this is allowable and follows my field (psychology).

The reference I did find: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5349281/
