Artificial Intelligence Ratings Of Facial Feature Similarity As Predictors Of Eyewitness Performance, Agata K. Bugajczyk

Student Theses

Eyewitness identification plays an important role in the criminal justice system, yet it is often prone to error. Diagnostic Feature Theory (DFD) suggests that lineup fillers should match the eyewitness’s description of the suspect but be different in other ways (Wixted & Mickes, 2014). According to this theory, people remember faces using multiple features (e.g., age, race, face shape), some of which are useful for recognition and some that are not. This approach has been shown to improve the ability to tell the difference between guilty and innocent suspects (e.g., Colloff et al., 2021), but it also increases identification rates …

Estimator And Reflector Variables In Eyewitness Recall, Sakshi Mundra

Student Theses

Eyewitnesses are frequently asked to describe culprits following a crime, but how accurate and complete are such descriptions? This study examined eyewitness description completeness and accuracy by investigating estimator variables (Race and Gender), reflector variables (Confidence and Response Time), and elicitation methods (Free Recall and Prompted Recall). Participants viewed one mock-crime video featuring a culprit who varied in race (White or Black) and gender (Female or Male), then provided free recall descriptions followed by prompted descriptions of facial features. Prompted recall improved completeness beyond free recall, though with a minor reduction in accuracy. Descriptions were more complete for same-race and …

A Meta-Analysis On Joinder Effects: Do They All Have The Same Magnitude?, Amelia M. Tisk

Student Theses

The present meta-analysis examined whether different forms of joinder and procedural consolidation produce varying levels of prejudice in adjudicative decision-making. Although joinder procedures improve judicial efficiency, psychological research has suggested that combining charges, defendants, or plaintiffs within a single proceeding may increase conviction likelihood, liability judgments, and broader perceptions of wrongdoing. A random-effects meta-analysis was conducted across 22 independent study effects examining charge joinder, defendant consolidation, plaintiff consolidation, multiple-complainant procedures, and related aggregation paradigms. Effect sizes were converted to Pearson’s r whenever possible. Overall, procedural aggregation produced a moderate effect on adjudicative outcomes, r = .27, 95% CI [.22, .32]. …

Understanding Mental Health Crisis Response Through The Lens Of First Responders, Ella Gibson

Student Theses

Responses to mental health crises are becoming an increasingly contentious topic as cases of extreme police violence or fatality during a crisis are publicized in the media. Although first responders’ experiences with mental health crisis response have been explored in prior literature, there remains a lack of research that gathers data from multiple first responder roles and compares their experiences across groups. There is also a significant gap in research examining the perspectives of co-response teams. This study sought to gather qualitative data on the experiences of police officers, EMTs/paramedics, and co-response team members, and to explore their perceptions of …

Eyewitness Consent To Be Video Recorded: Implications For Identification Accuracy And Confidence, Sarah Argüelles

Student Theses

Recently, a recommendation has emerged for law enforcement to record the full eyewitness identification procedure, recognizing the critical role eyewitness testimony plays in the justice system (Wells et al., 2020). However, in some states, such as New York, law enforcement is required to seek consent from witnesses before recording (Municipal Police Training Council & Division of Criminal Justice Services, 2017). Since this practice is relatively new, there has been limited research on how obtaining consent may affect eyewitness accuracy. It was hypothesized that obtaining consent to video record could be linked to a witness’s confidence in their identification, with higher …

Rape Myth Acceptance, Pretrial Publicity, And Decision-Making: An Examination Of Perceptions Of Victim Credibility And Perpetrator Guilt In A Real-World Sexual Assault Case, Lindsey Strouse

Student Theses

This study explores how the media narratives and political perspective of pretrial publicity (PTP) can influence jurors’ perceptions in sexual assault cases, raising significant concerns about justice in courtrooms. Specifically, it examines whether media framing of a real-life sexual assault case — through varying media narratives, with media that either challenges or endorses rape myths, and media source (liberal vs. conservative) — affects mock jurors’ rape myth acceptance (RMA), views of victim credibility, and judgements of perpetrator guilt. Participants first completed a RMA scale, then read mock news articles varying in media narrative and political affiliations (media source), followed by …

The Impact Of Mental Health Courts On Public Attitudes Held Toward Justice-Involved Individuals With Mental Illness, Maeve Porter

Student Theses

Prior research has established that mental health court programs play an important role in reducing recidivism and mental health symptoms of defendants. However, there is a lack of understanding of the stigma that justice-involved individuals may encounter upon release from mental health court into the community, and the extent to which the general public is aware of mental health court programs. The present study sought to address public perceptions regarding mental health courts, their efficacy, and their participants based on the awareness and availability of these specialized courts in two similar states (New York and New Jersey), one in which …

Punitive Desire, Belief In Redeemability, And Support For Rehabilitation: A Comparison Of Victimized And Non-Victimized Individuals' Attitudes Toward Criminal Offenders, Caleb Linder

Student Theses

This study examined the attitudes of victimized and non-victimized individuals toward criminal offenders, investigating whether the supportive attitudes observed in Spoo et al. (2018) extend beyond sexual offenses to other types of crime. The study also explored how the perpetrator’s relationship to the victim (family member vs. stranger) and participants’ previous exposure to the justice system influenced their perceptions of offenders. Contrary to our hypothesis, punitive attitudes did not differ between participants with a history of victimization and those without. Additionally, there was no significant difference in punitive attitudes toward stranger offenders compared to offenders known to the victim. Furthermore, …

Examining The Impact Of Expert Testimony And/Or Mindfulness Training On Jurors’ Appraisals Of False Confessions, Izabela Rzaca

Student Theses

False confessions continue to be the leading cause of wrongful convictions in the United States, often because of coercive interrogation tactics (Kassin, 2008; Leo & Ofshe, 1998). Jurors frequently view confession evidence as highly persuasive, even when situations suggest it may be false (Kassin & Sukel, 1997). A confession becomes important when there are no other forms of evidence against the defendant, especially in cases where police detectives are pressured to decipher the crime (Gross, 2004). Additionally, confessions have shown to override other types of evidence when jurors make their decisions (Leo et al., 2013). To address this issue, the …

Helpful Intentions? Impact Of Intentionality On Children's Memory For Forensically-Relevant Information, Ella P. Merriwether

Dissertations, Theses, and Capstone Projects

Rationale: When a child is a witness or victim of a crime, they are often asked a barrage of questions regarding when the crime took place, how many times it occurred, and how the abuse unfolded (Cross & Whitcomb, 2017; Sullivan et al., 2022). These questions can be problematic because they rely on concepts for which children may lack memory or linguistic ability to answer (Fenson et al., 2000; Friedman, 1993). One fundamental element missing from the copious research (e.g., Brubacher et al., 2012; Stolzenberg et al., 2017a; Wylie et al., 2021) on children’s ability to recount forensically-relevant information is …

Brain Injury And Psychosocial Trauma: Outcomes Among Justice-Involved Individuals, Mahathi D. Kosuri

Dissertations, Theses, and Capstone Projects

Justice-involved individuals experience disproportionately high rates of both traumatic brain injuries (TBI) and psychosocial traumas. However, these traumas have yet to be conceptualized together, leaving a chasm of research on how they interact and influence this population. The current study was the first to measure the effects of TBIs as well as psychosocial trauma among justice-involved men, within the context of executive functioning, history of justice involvement, and recidivism. A sample of men (N=95) from a private correctional facility were given the Ohio State University Traumatic Brain Injury Questionnaire (OSU-TBI-ID), the Lifetime Stressor Checklist- Revised (LSC-R), along with …

Human Trafficking Screening Tools Amongst Migrants And Refugees: Current Tools And Future Outlooks, Audra Fox

Student Theses

While various human trafficking screening tools exist to help stakeholders identify indicators and risk of trafficking, few tools are designed specifically for use amongst migrants and refugees. Via interviews with anti-trafficking stakeholders, the following qualitative study describes what tools stakeholders currently use to asses trafficking amongst migrants and refugee, and if stakeholders desire a new tool specific for migrant/refugee populations. Thematic results indicate that most stakeholders are not using validated tools for trafficking victims, let alone migrants and refugees (n=5, 38.5%). Of the total sample, 62% of participants (n=8) reported various screening discrepancies across stakeholders. Additionally, …

Phenotypic Mismatch Between Suspects And Fillers But Not Phenotypic Bias Increases Eyewitness Identifications Of Black Suspects, Jennifer M. Jones, Jacqueline Katzman, Margaret Bull Kovera

Publications and Research

Despite converging evidence that people more closely associate the construct of criminality with Black people who exhibit a more African facial phenotype than Black people who express a more European phenotype, eyewitness researchers have largely ignored phenotypic bias as a potential contributor to the racial disparities in the criminal legal system. If this form of phenotypic bias extends to eyewitness identification tasks, eyewitnesses may be more likely to identify Black suspects with an African rather than European phenotype, regardless of their guilt status. Further, in cases where the witness’s description of the perpetrator does not contain phenotypic information, phenotypic mismatch …

Bargaining In The Shadow Of The Truth: How Client Assertion, Perception Of Guilt, And Predictive Inaccuracy Influence Plea Recommendations, Anna D. Vaynman

Dissertations, Theses, and Capstone Projects

Over the past few decades, the largely hidden, secretive, and widely used system of plea bargaining has caught the fervent attention of scholars. The Shadow of the Trial model has been central to much of the plea-bargaining literature, despite significant critiques about its oversimplification. The model posits that defendants and their attorneys make plea decisions based largely on the estimated probability of conviction and the severity of the sentence to which the defendant could be exposed at trial.

The model, however, assumes that all actors are rational, equally risk averse, have no competing interests, and possess high predictive accuracy. It …

Epistemic Virtue And Receptivity To Science In Policing, Braden L. Campbell

Dissertations, Theses, and Capstone Projects

This dissertation investigates the underexplored relationship between character epistemology and its potential to explain behavior, decision-making, and culture within the criminal justice system, particularly the police. Building on the existing theoretical framework of evidence-based policing (EBP) and the recognized gap in understanding police receptivity to science, this study hypothesized that intellectual character at personal and collective levels positively correlates with science receptivity.

Epistemic character was defined through the aggregation of four traits: open-mindedness, defensiveness, insouciance, and groupthink. Science receptivity was measured by openness to change, desire to learn, reliance on intuition, and mistrust of science. Data were collected through surveys …

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 …

The Association Between Mental Health Diagnoses And Trial Competency Assessments In Defendants: A Meta-Analysis, Danielle C. Severe

Student Theses

In the realm of trial competency evaluations, there are a variety of methods used to evaluate whether an individual is fit to stand trial. Presently, forensic psychologists conduct trial competency evaluations in order to assess one’s ability to stand trial, but for persons with a mental health diagnosis, the generic competency measures are not the most effective means to assess one’s ability to stand trial, as mental health diagnoses impair cognitive functions that are required in judicial proceedings. Forensic psychologists have opted to utilize other assessment methods such as the MacArthur Competence Assessment Tool – Criminal Adjudication [MacCAT-CA] and Fitness …

The Role Of Suspect Development Practices In Eyewitness Identification Accuracy And Racial Disparities In Wrongful Conviction, Margaret Bull Kovera

Publications and Research

This article reviews the three previously studied categories of variables that are related to eyewitness identification accuracy: estimator (characteristics of the witnessing conditions), system (characteristics of the identification procedure that are under the control of the criminal legal system), and reflector (variables that reflect the likely accuracy of a witness). Although eyewitness scholars frequently turn to these variables and models of memory to explain why eyewitnesses make mistakes, none of these variables provides a reasonable explanation for the large racial disparities in wrongful convictions based on mistaken identifications, yet problematic policing practices might. The policies and practices guiding police efforts …

Potential Causes Of Racial Disparities In Wrongful Convictions Based On Mistaken Identifications: Own-Race Bias And Differences In Evidence-Based Suspicion., Jacqueline Katzman, Margaret Bull Kovera

Publications and Research

Objective: We explored whether racial disparities in evidence-based suspicion (i.e., evidence of guilt prior to placement in a lineup) provide a better explanation of racial disparities in exonerations based on eyewitness misidentification than the own-race bias in eyewitness identifications. Hypotheses: We predicted that the own-race bias in identification accuracy would be insufficiently large to fully explain the racial disparities in wrongful convictions in cases with mistaken identification. We also predicted that possible racial disparities in the prior probability of suspect guilt before subjecting suspects to the risk of misidentification might better explain racial disparities in wrongful convictions. Method …

Traumatized Defendants, Troubled Attorneys: The Impact Of Vicarious Trauma On The Defense Attorney-Client Relationship, Charise Peters

Student Theses

Approximately 90% of justice-involved youth have experienced some form of trauma by the time they become involved in the justice system, and attorneys report being negatively impacted by their work with trauma-exposed populations generally. Yet, research has not focused on how varying degrees of youth trauma can impact attorney decisions and if that differs based on youth race. This study, therefore, explored vicarious trauma and its impact on juvenile defense attorneys, including how an attorney’s experience of vicarious trauma impacts case handling and perception of their youth client and how that differs based on client race and trauma history. We …

Perception Of Police And The Mediation Of Memory Distortion Via Trauma: Body Worn Camera Footage Of An Emotional Police-Citizen Encounter, Arlyn Abreu

Student Theses

This present study calls to question the objectivity of police body-worn camera (BWC) footage. Proponents assume that BWCs will be a panacea in a climate of heightened tensions between officers and communities. In spite of this, our findings challenge the rhetoric, and the purpose BWC is intended to serve. We explored its implications on memory distortion by posing two questions (a) can people come to remember BWC footage as more traumatic than they initially experienced (b) to what degree can external information and internal influences impact peoples' judgment about a traumatic event. We addressed both questions in this two-part study, …

Inducing Empathy In Jurors In A Capital Penalty Phase Trial: An Examination Of How To Reduce Jurors' Death Sentence Decisions, Klaudia Zuraw

Student Theses

The present research explores whether inducing empathy in death-qualified mock jurors leads to fewer death sentences in a penalty phase trial. Previous research has shown that inducing empathy in jurors leads to lesser sentences and perceived responsibility of the perpetrator for the crime. However, none of this research has examined death penalty cases, and most have focused on instances where the victim was also the perpetrator of a separate crime against the defendant (e.g., abuse). Extending this line of research, the present study examines whether these results extend to instances where the perpetrator and victim are strangers. Additionally, considering the …

Intellectual Disability, Risk, And Recidivism In An American Sample Of Incarcerated Sexual Offenders, Perry A. Callahan

Student Theses

Research suggests that intellectual disabilities (ID) are prevalent among people who sexually offend. Those with ID may differ from their non-disabled counterparts with regard to risk factors associated with recidivism. Additionally, actuarial measures of risk, which are used to make determinations on sentencing and civil commitment, appear to differ in their predictive accuracy among individuals with and without ID. Despite this, little data exists on recidivism in this population, particularly among incarcerated individuals in the United States. The present study sought to compare individuals with and without ID on rates of re-offense, actuarial risk scores, and rates of civil commitment. …

The Coercion Of The Trial Penalty, Kristen C. Akin

Student Theses

Prosecutors, defendants, and defense attorneys must make decisions as to whether to accept a plea offer or proceed to trial every day. Approximately 95% of state and federal convictions result from guilty pleas (Redlich et al., 2017; Thaxton, 2013; Gazal-Ayal & Tor, 2012; Redlich & Shteynberg, 2016; Edkins, 2011; Weatherly & Kehn, 2013; Helm et al., 2018; Gregory et al., 1978). Some estimate this number to be as high as 97% to 99% (Redlich & Bonventre, 2015; Helm et al., 2018). It is also estimated that every two seconds a defendant pleads guilty (Redlich & Bonventre, 2015). In 1980, 19% …

Children’S Ability To Understand And Respond To Wh- Questions About The Mechanics Of Abuse, Kaileigh P. Conti

Student Theses

One type of forensically-relevant information that can be difficult to obtain is that pertaining to the “mechanics of abuse.” More specifically, information that includes the descriptions of body positioning and clothing placement. Generally, the recommended strategy for questioning children in legal and forensic settings is to use broad invitations (e.g., “Tell me everything that happened”) and wh- questions (e.g., who, what, where, when, why, how). However, when it comes to the mechanics of abuse, there is some conflicting evidence. Some research suggests open-ended wh- questions are best in cases where the mechanics are hard to describe (e.g., intermediate clothing placement) …

Individuals Who Have Been Convicted Of A Sex Offense: Attitudes On Legislation And Policy, Brenna L. Scott

Student Theses

Sex offender legislation, both at the state and federal level, was designed to keep communities safer. However research suggests that many of these laws do not decrease recidivism and in some cases may increase risk for reoffending. Despite this there has been little movement to repeal these laws. As such, it is important to understand how the current legislation impacts individuals who have committed a sex offense and their ability to successfully reintegrate into communities post-incarceration and what if anything can be done to improve existing laws. The current study surveyed 46 individuals convicted of sex offenses about their opinions …

The Influence Of Prosecutorial Overcharging On Defendant And Defense Attorney Plea Decision Making: Documenting And Debiasing The Anchoring Effect, Stephanie Aurora Cardenas

Dissertations, Theses, and Capstone Projects

Strategic overcharging, a practice that some prosecutors readily employ to threaten defendants with excessively severe sentences, undermines the Sixth Amendment right to trial by coercing defendants to plead guilty rather than face penalties disproportionate to their alleged misconduct. Legal scholars and psychologists have long suggested that strategic overcharging may elicit powerful anchoring effects that bias defendants’, but not attorneys’ evaluations, of the plea offer. The current research sought to examine (a) the extent to which mock defendants and legal professionals were susceptible to the anchoring bias, (b) elucidate the mechanism underlying susceptibility to the anchoring effect in plea contexts, and …

The Psychological Allure Of Alford: Why Innocents Plead Guilty, Johanna Hellgren

Dissertations, Theses, and Capstone Projects

The Alford plea allows defendants to maintain their innocence while accepting a plea. Although this plea is more prevalent than jury trials, it is largely unknown to both lay people and researchers (Redlich & Özdoğru, 2009). Legal scholars have argued that the Alford plea may present an undue influence on innocent defendants who may not otherwise accept a plea, while other assert that the Alford plea is a beneficial alternative for defendants who want to preserve their reputation (Ronis, 2009; Ward, 2004). However, no research to date has explored either of these assumptions.

The goals of the current research were …

The Online Impossible Anagram Task: Development And Testing Of A Novel Online Cheating Paradigm, Emily Joseph

Dissertations, Theses, and Capstone Projects

For the past fifteen years, the Russano et al. (2005) cheating paradigm has dominated research in the forensic psychological literature. While this paradigm successfully activates theoretical mechanisms for ethical decision-making, applying the methods for online data collection is cumbersome and retains a confound inherent in the design. Alternative cheating paradigms from both the psychology and economics literatures were evaluated for their suitability for an online cheating paradigm. The impossible anagram task was selected as most likely to elicit the same internal and external cost-benefit analyses online as the Russano et al. (2005) cheating paradigm does in-person: self-concept maintenance, ethical dissonance, …

Parental Plea Bargain Recommendations To Their Child In A Juvenile Court Setting, Aliya J. Birnbaum

Student Theses

This study examined parent acquiescence to attorney recommendations pertaining to plea bargain decisions, as well as whether this differed based on the racial similarity between an attorney and their juvenile client’s parent. Past research has shown that youth are vulnerable to the influence of perceived authority figures in a plea-bargain setting, leading them to rely heavily on the input of their parents and attorneys for how to plead. This study expands the literature to include how attorney race impacts parents’ plea decisions. A sample of parents of youth aged 11- 17 read a vignette, in which attorney race was manipulated, …
