A literature review may consist of simply a summary of key sources, but in the social sciences, a literature review usually has an organizational pattern and combines both summary and synthesis, often within specific conceptual categories.
A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information in a way that informs how you are planning to investigate a research problem.
Then discusses how the next researchers tried to address these problems.
the results obtained from studies using stories and word lists as stimuli can be generalised to forensic contexts.” …
Integrative Review Considered a form of research that reviews, critiques, and synthesizes representative literature on a topic in an integrated way such that new frameworks and perspectives on the topic are generated.
The body of literature includes all studies that address related or identical hypotheses or research problems.
Almost all innocent individuals exonerated by DNA evidence had been convicted primarily as a result of erroneous eyewitness evidence (ref.) Consequently, a great deal of research has focussed on the unreliability of eyewitness testimony (refs.).” , such a narrow focus may not fully explain how people remember (ref.). Reviews the chronological development of research in this area (an approach that is useful at times, but not always the best).
Because such ‘contamination’ is common to memory, understanding its effects enables greater knowledge of memory itself (ref.). Discusses one key paper at a time by describing its methods and key findings, but then identifies weaknesses in the method and/or limitations in the findings.
A literature review surveys books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory, and by so doing, provides a description, summary, and critical evaluation of these works in relation to the research problem being investigated.
Literature reviews are designed to provide an overview of sources you have explored while researching a particular topic and to demonstrate to your readers how your research fits within a larger field of study.
