I'm currently writing the literature review for my dissertation on a new theory in language learning motivation. The theory has links/connections and key differences to theories which came before. My question is, as the author of this new theory has already summarised the theories in which it is similar too (and has mentioned the differences and how this new theory expands and accounts for these differences), am I allowed to follow a similar style and use similar references in my literature review? I want to mention these theories/discuss them etc. and mention how this new theory ties loose ends. However, I want to be careful to avoid plagiarism. Obviously, I'm not going to copy any of the author's summarisations, but I want to use the same references.
Can anybody who has done a dissertation/lit-review and has maybe encountered the same dilemma as I have offer any advice?
