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 …

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 …

Quantitative And Qualitative Assessment Of Interrogation Expectations, Shereen R. Lewis

Student Theses

Interrogation expectations (IE) is a construct that suggests expectations of custodial interrogations affect suspects’ Miranda waiver decisions while under interrogation. Prior research has examined IE quantitatively but there has been no prior research examining IE qualitatively. This current research conducted both a quantitative and qualitative analysis of IE using a sample of 335 participants from the United States. This research took the form of an online survey using Prolific (www.prolific.co) to recruit participants, Qualtrics (www.qualtrics.com) to record data, and SPSS and Nvivo to analyze quantitative qualitative data. It was hypothesized that substantial individual variation in IE will be found in …

Development And Validation Of A Multidimensional Scale For Measuring Public Confidence In The Criminal Justice System, Jimin Pyo

Dissertations, Theses, and Capstone Projects

Two studies were conducted with an aim of developing multidimensional measures of public confidence that are conceptually integrated, psychometrically sound, and useful in predicting individuals’ law related behaviors. Study 1 involves two-phased construction of scale in which a preliminary inventory was generated (Phase 1) and then finalized after evaluating psychometric properties based on 304 US adults recruited through Amazon’s Mechanical Turk (MTurk) (Phase 2). As a result, six multidimensional scales were constructed respectively for measuring efficiency-, finality-, fairness-, strictness-, accuracy-, and transparency-oriented confidence. Despite more complexity of factor structures than originally expected, results of psychometric evaluation six scales of confidence …

Wrongful Conviction Documentaries: Influences Of Crime Media Exposure On Mock Juror Decision-Making, Patricia Y. Sanchez

Dissertations, Theses, and Capstone Projects

Psychology and law researchers have urged colleagues to collaborate with the makers of popular media, such as documentary filmmakers, in efforts to educate the general public about wrongful convictions (Kassin, 2017; Wells et al., 2000). Recently, programs depicting wrongful convictions, such as Making a Murderer (Demos & Ricciardi, 2015) and When They See Us (DuVernay, 2019) have garnered substantial viewership. Research on general and case-specific pretrial publicity (Daftary-Kapur et al., 2014; Kovera, 2002) and the effects of crime media (Baskin & Sommers, 2010; Schweitzer & Saks, 2007) demonstrate that although consuming crime-related media and being exposed to information about a …

Juveniles Tried As Adults:The Impact Of Youth Demographic Factors On Juror Perceptions, Denieka Ellis

Student Theses

Abstract: This study explored the impact of defendant age, race and stereotypic crime on verdicts and recommended sentencing of juveniles tried as adults. Previous research shows that jurors enter trial with negative preconceptions and biases of juveniles because they are being tried within an adult venue. These negative preconceptions have led jurors to recommend harsher sentencing for juveniles rather than adults with the same defendant characteristics and criminal history. Crime type and crime severity have also been shown to impact perceptions of juvenile defendants in adult court. However, research has not yet explored the potential impact that stereotypic crime—a crime …

Felony Disenfranchisement: Factors Relating To Support For Restoration, Alexis K. Karpf

Student Theses

Felony Disenfranchisement, a collateral consequence, strips justice-involved individuals of their voting rights. While this policy is enacted in 48 states and the District of Columbia, a majority of community members are unaware of its existence. The current study used three hypotheses to guide its research about how education about disenfranchisement policy impacts a community member's opinion:1) Participants exposed to information about the effects of disenfranchisement will be more supportive of enfranchisement than those in the control condition; 2) Participants who receive the vignette featuring the White justice-involved individual will indicate a higher level of support for enfranchisement compared to those …

The Role Of Eyewitness Confidence And Prosecution/Defense Presentation In How Facial Composites Shape Juror Decision-Making, Rebecca E. Singh

Student Theses

Eyewitness testimony has been found to be an unreliable form of evidence (Loftus, Miller & Burns, 1978; Oswald & Coleman, 2007; Wells & Hasel, 2007; Loftus & Greenspan, 2017; Jaross, 2018; Wade, Nash, & Lindsay, 2018; Wixted, Mickes, & Fisher, 2018). Yet, this evidence is still used in the courts today, and, in fact, is perceived by jurors as important and compelling in comparison to other case factors (e.g., character evidence, physical evidence; Topp-Manriquez, McQuiston, & Malpass, 2014; Kabzińska, 2015). Additionally, eyewitnesses are sometimes requested to help create a facial composite of the suspect and, critically, these composites are then …

Linguistic Features Of False Confessions And Confessions Not In Dispute: A Corpus Analysis, Lucrezia Rizzelli

Student Theses

Confessions are considered the gold standard of evidence, and yet many cases of false confessions causing wrongful convictions have come to the surface in the past decades. Currently, a method to identify false confessions does not exist and studies focusing on the content of the confessions have found similarities rather than points of distinction. In this study, we approached confessions from a stylistic rather than qualitative point of view, utilizing corpus analysis to outline the linguistic features of two samples of confessions: false confessions (n=37) and confessions not in dispute (n=98). Subsequently, we created a model …

Bait Questions As Source Of Misinformation In Police Interviews: Does Race Or Age Of The Suspect Increase Jurors' Memory Errors?, Matilde Ascheri

Student Theses

Bait questions—hypothetical questions about evidence, often used by detectives during interrogations—can activate the misinformation effect and alter jurors’ perceptions of the evidence of a case. Here, we were interested in investigating whether mock jurors’ implicit biases could amplify the magnitude of the misinformation effect. We accomplished this by manipulating the age and race of the suspect being interrogated. As an extension of Luke et al. (2017), we had participants read a police report describing evidence found at a crime scene, then read a transcript of a police interrogation where the detective used bait questions to introduce new evidence not presented …

Criminal Responsibility: Meta-Analysis And Study Space, Lauren E. Kois

Dissertations, Theses, and Capstone Projects

Criminal responsibility (CR; i.e., sanity) has garnered significant research attention over the years. While some variables predicting insanity outcomes are consistent, others are not. Study-level characteristics, such as sample selection, variability in the operational definition of insanity, or other unknown influences may explain discrepant findings. It is critical to consolidate these variables and systematically assess differences in methodology to understand the state of the literature and to guide future research. As such, I conducted the first meta-analysis and study space analysis (see Malpass et al., 2008) in this area. Only 16 studies met inclusion criteria for the meta-analysis. Summary effects …
