An Archival Exploration Of Lineup Fairness In Eyewitness Research, Phoebe Kane
An Archival Exploration Of Lineup Fairness In Eyewitness Research, Phoebe Kane
Student Theses
In this study, we were interested in investigating if the Betaface facial analysis program reliably predicts eyewitness lineup choosing behavior. If face analysis programs are as good or better than human judgements, using them could be a reliably more efficient, reproducible, and equitable basis for choosing fillers and evaluating lineup fairness. We collected 27 datasets from eyewitness researchers and analyzed them to produce Betaface similarity values, which measured the similarity between all the photos in each array. We compared these Betaface data to the identification data from the original studies. Our analysis of the arrays via Betaface yielded data with …
Juror's Perceptions Of Evidence-Based Suspicion, Nicholas Welter
Juror's Perceptions Of Evidence-Based Suspicion, Nicholas Welter
Student Theses
Eyewitness misidentification is a leading cause of wrongful conviction. Although the prior probability of guilt (i.e., pre-identification evidence strength) is the most important factor for predicting a defendant’s actual guilt status and the accuracy of any subsequent eyewitness identification, no study has examined whether it affects juror decisions. This oversight is problematic because when officers place suspects in lineups when there is little evidence connecting them to the crime, it falls on jurors to examine the probative value of identification evidence. Participants (N = 357) watched a mock trial depicting an armed robbery that varied pre-identification evidence (strong vs. …
The Dud Effect: The Effect Of Dissimilar Fillers In Eyewitness Lineups, Shannon Booth
The Dud Effect: The Effect Of Dissimilar Fillers In Eyewitness Lineups, Shannon Booth
Student Theses
Similarity and confidence are often analyzed in relation to eyewitness accuracy. Duds, highly dissimilar fillers, can impact an eyewitness’ accuracy and confidence. This study analyzed the impact of duds, similarity and accuracy in the context of lineup bias. This study found that in target-absent conditions there is a significant positive relationship between lineup bias and confidence. This study also found that highly similar lineups results in a lower proportion of correct identification, even in highly confident witnesses, compared to medium similar and low similar lineups. Further research should look closer at the “sweet spot” of similarity in order to advise …
911 Dispatchers: Their Role As Evidence Collectors, Brittany P. Kassis
911 Dispatchers: Their Role As Evidence Collectors, Brittany P. Kassis
Student Theses
911 dispatchers are often the first point of contact after an individual is in an accident, needs emergency assistance, or witnesses a crime. In an emergency involving a crime, a dispatcher can play an important role in assisting the investigative process and collecting evidence, such as an eyewitness’ description of the suspect. While trained in how to gather situational and locational information from a caller so that relevant first responders can be notified, dispatchers may not be trained on how the specific language they use with a caller can impact the caller’s memory for the event. Thus, if dispatchers are …
The Effect Of Phenotypic Bias On Lineup Construction Fairness, Sydney Y. Wood
The Effect Of Phenotypic Bias On Lineup Construction Fairness, Sydney Y. Wood
Student Theses
There is converging evidence that people make inferences about others’ culpability and deservingness of punishment based on whether they express more of the African phenotype (e.g., darker skin, wider nose, thicker lips; Blair, Judd, & Chapleau, 2004; Eberhardt Goff, Purdie & Davies, 2004; Kahn & Davies, 2011). What is less clear is whether facial features that are phenotypically related to particular racial groups play a role in the mistaken identification of innocent Black suspects. Eyewitness descriptions lack detail with regard to racial phenotypes (Fahsing, Ask & Granhag, 2004; Nicholson & Kovera, 2013). Without descriptions containing phenotypic features to use when …
