The Influence Of A Showup Identification On A Subsequent Witness Description, Kelsey Lynne Hess

FIU Electronic Theses and Dissertations

Showups account for 30%-77% of initial identification procedures conducted by police (Flowe et al., 2001; Gonzalez et al., 1993; McQuiston & Malpass, 2001). Unlike lineups, showups are typically administered within a few hours of the crime event. The administration of a showup, due to its timing, is likely to precede a more formal police interview. The showup may introduce new characteristics of the suspect’s physical appearance to the witness. Any new characteristics inconsistent with the perpetrator’s appearance at the crime can be considered misinformation, which has the potential to contaminate witness recall. Although the contaminating effects of a showup have …

A Novel Approach To Studying Human Intelligence-Gathering: Employing A Realistic Paradigm For The Study Of Elicitation Approaches, Sarah A. Shaffer

FIU Electronic Theses and Dissertations

It is often necessary to interrogate sources of information when threats to national security (e.g., impending terror attack) are present. However, the overwhelming majority of research focuses on the interrogation of criminal suspects despite the arguably greater consequences of the former context, known as Human Intelligence (HUMINT) collection. The present study is the first to examine a highly successful approach to collecting information from sources of human intelligence (HUMINT)- the Scharff Technique.- within a novel and highly realistic paradigm. Participants were recruited for a study on group interaction. Every group contained a study confederate posing as a participant who gave …

Informants' Memory For Conversations: The Examination Of The Investigative Utility Of The Cognitive Interview, Danielle Sneyd

FIU Electronic Theses and Dissertations

In human-intelligence-gathering contexts, informants or persons of interest are often interviewed about a conversation they overheard. The information gathered from these conversations may be important for national security, and therefore, the most accurate information needs to be elicited. The current project consisted of two studies that extended the previous literature on the Cognitive Interview (CI). Study 1 (1) tested the CI (compared to a structured interview, SI) in the context of memory for conversations and (2) investigated the effects of modality by comparing in-person interviews to telephone interviews. The CI is a theory-based interview protocol that has been shown to …

The Effects Of Cognitive Bias, Examiner Experience, And Stimulus Material On Forensic Evidence Analysis, Michelle M. Pena

FIU Electronic Theses and Dissertations

Forensic examiners have come under scrutiny in recent years because of high profile exoneration cases that have highlighted the negative impact contextual bias can have on investigations including forensic evidence analyses. This has led to several proposed solutions to reduce the effects of bias including blind testing and redacting task-irrelevant information. However, practitioners have not been receptive to such recommendations because of the limitations found in past research, such as the use of untrained undergraduate students to examine complex pieces of forensic evidence (e.g., fingerprints). The current study thus had the following aims: (a) examine the effect of contextual bias …

Eliciting A Perpetrator Description Using The Cognitive Interview: Influences On Investigative Utility, Geri Satin

FIU Electronic Theses and Dissertations

The Cognitive Interview (CI) has been shown in over one hundred studies to enhance eyewitness recall. However, no study has explored whether the CI improves police job performance. The current study was the first to test the practical value of the CI in a criminal investigation, testing participants’ performance on key police tasks using either a perpetrator description elicited from a CI or from a standard police interview (SI).

In an earlier study, student witnesses were exposed to a simulated robbery and were then interviewed using either a CI or an SI to elicit a description of the robber (comprised …

Eyewitness Choosing Behavior: The Role Of Ecphoric Experience And Non-Memorial Cues, Brian S. Cahill

FIU Electronic Theses and Dissertations

Researchers’ attempts at understanding the processes underlying witness choosing behavior have focused on applying models that predict that identifications will be primarily driven by memorial factors. However, research has shown that several non-memorial variables affect witness choosing behavior (e.g., administrator influence, clothing bias, co-witness information); thus a full understanding of the processes underlying witness choosing behavior needs to account for these effects. While the memory-based models do attempt to provide explanations for the effects of non-memorial based variables on choosing behavior they all do so within a memorial context. However, I will argue a lineup task is not simply a …

It Must Have Been Him: Coherence Effects Within The Legal System, Jonathan N. Carbone

FIU Electronic Theses and Dissertations

The present series of studies examine how jurors and public defenders evaluate different pieces of evidence and integrate them into a coherent conclusion within the context of a criminal case. Previous research has shown that in situations where both sides of the case are compelling, decision-makers nevertheless come to highly confident and polarized decisions, called coherence shifts (Simon, 2004). The present research sought to expand on coherence effects, improve upon the methodology of previous studies, and explore potential moderators of coherence. In Study 1, mock jurors (n = 306) read about a criminal case and evaluated multiple pieces of …

The Effects Of Post-Recall Feedback: Examining Witness Recall Quantity, Accuracy, And Confidence, Dana Elizabeth Hirn Mueller

FIU Electronic Theses and Dissertations

Most eyewitness identification protocols recommend withholding feedback after an identification has been made, at least until a measure of confidence can be gathered. Although much research has examined the impact of post-identification feedback on subsequent witness behavior and confidence, research addressing the importance of post-recall feedback remains largely incomplete. The current study examined the effects of post-recall feedback and question type on subsequent witness recall, confidence, and reports of view of the crime. In line with previous eyewitness identification research, it was predicted that participants receiving confirming post-recall feedback would be more confident in their prior recall compared to participants …

Understanding Rapport-Building In Investigative Interviews: Does Rapport's Effect On Witness Memory And Suggestibility Depend On The Interviewer?, Jenna M. Kieckhaefer

FIU Electronic Theses and Dissertations

Most investigative interviewing protocols, including the National Institute of Justice’s 1999 guidelines on collecting eyewitness evidence, recommend building rapport with cooperative witnesses to increase the quality and quantity of details obtained at recall. To date, only three published articles have empirically addressed the effects of rapport-building on adult witness memory, and all suggest an increase in witness accuracy under certain conditions. However, to our knowledge no research has addressed the importance of the investigator when building rapport and whether rapport can increase witness susceptibility to suggestive-leading questions – the aim of the current research. Specifically, this project examined the effects …
