🌷Summary of Literature is primarily used amongst descriptive studies and introductory moments in order to list and articulate some researches, so therefore the synopsis barely consists of appropriate interpretation for itself.
The main thing you might do about the summary is to list researches and its integral parts in any subsequences, because this type of review should never have a flowing point until it is the summary.
🌷 Literature Review is a sufficient piece of what-you-call "research", because its functions are set to compare, differentiate, and derive similarities between the searched scientific projects.
In spite of its superficial resemblance to the Summary of Literature, the last one would and should never flow comparisons and analysis with deep focus on methodologies and other parts of the researches being observed.
🍭Use a summary when you need to report what a text says. Use a literature review when you need to build an argument about what the body of research as a whole shows.
If you write, “Study 1 found higher depression scores, and Study 2 found the same,” that is a summary. If you write, “Across studies, higher depression scores appear consistently, but findings vary by sample and measurement method,” that is a literature review-style synthesis.
