The format of a review of literature may vary from discipline to discipline and from assignment to assignment.
A review may be a self-contained unit — an end in itself — or a preface to and rationale for engaging in primary research.
A review is a required part of grant and research proposals and often a chapter in theses and dissertations.
Generally, the purpose of a review is to analyze critically a segment of a published body of knowledge through summary, classification, and comparison of prior research studies, reviews of literature, and theoretical articles.
The overall goals of this chapter were firstly to establish the significance of the general field of study, then identify a place where a new contribution could be made.
The bulk of the chapter was on critically evaluating the different methodologies used in this field so as to identify the appropriate approach for investigating the research question(s). “Approximately 77,000 individuals are arrested in the United States each year based primarily on eyewitness testimony (ref.). Given the pivotal role that eyewitness testimony plays in some trials, it is important to establish whether or not the jury’s faith in this testimony is warranted.” 2.
“ on collaborative memory is that the memory of groups is compared with that of individuals. group performance should not be compared with individual performance but rather with ‘nominal groups’ comprised of pooled, non-redundant data from the same number of people tested individually.” 8. Most research involving the Experimentally Induced Information methodology seeks to identify the influence of misinformation presented by one witness to another, and therefore the assumption is made that discussion between witnesses is a detrimental process. “While the misinformation effect is a well-established phenomenon, ‘what remains in dispute is the nature of a satisfactory theoretical explanation’ (ref.). Therefore, in order to understand why memory conformity occurs, we must draw from both cognitive research on memory and social research on conformity.
In this section, relevant cognitive and social theories are discussed in order to (1) explain the occurrence of memory conformity and (2) describe factors that influence memory conformity.” 3.
“Whilst biased guessing may account for the misinformation effect that occurs in some instances (refs.), research suggests that it is not the only reason for the occurrence of the misinformation effect. This suggests that the misinformation effect may be due at least partially to memory impairment, rather than just biased guessing.” 5.
Sums up what has been learned from the review of the four current theoretical explanations. “Informational influence, biased guessing, and modification of memory may help to explain why memory conformity occurs when participants are tested individually, as they are in the studies presented in this thesis. The research presented in this thesis compares these alternative explanations to determine which best explains memory conformity in individual recall following co-witness discussion. “One way to determine whether memory conformity occurs because of biased guessing is to …” “Experiments described in this thesis (Studies 5-7) include a warning for some participants about possible misinformation in an attempt to determine whether participants report misinformation because of informational influence or memory change.” 7.
