Diagnostic Featural Detection Or Filler Siphoning: A Red Box Study, Brynn Schuetter

Psychological Science Undergraduate Honors Theses

The current study is a replication and extension of previous research by Colloff and Wixted (2020). In their study, they created a novel identification procedure called the simultaneous showup. They found support for the diagnostic feature detection theory over the filler siphoning theory. The current study was interested in seeing if covert filler siphoning was still occurring in their novel procedure by asking participants how photos of fillers influenced their identification decision. Participants of the study viewed two crime videos and completed an identification task. If they were assigned to the simultaneous showup task, they were asked if and how …

Indicators Of Deception: Science Or Non-Science, Kristina Vasquez

Undergraduate Honors Theses

Deception detection is used by many law enforcement professionals who work in interviews and interrogations. The ability to detect deception or having knowledge on the signs of deception is very important in not only law enforcement, but in other careers and everyday life. The question remains: is deception detection a science or not a science? There are three areas where someone can learn how to detect deception and those are verbal communication, non-verbal communication, and paralanguage. The use of verbal communication looks at what the person is saying with their words. The use of non-verbal communication looks at what someone …

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 …

Jurors' Perceptions Of False Confessions, Madison G. Gallimore

Graduate Theses, Dissertations, and Problem Reports

This study examined the effect of mock jurors’ perceptions of a defendant’s false confession vs. no confession (false confession presence), coercive interrogation techniques vs. panic-escape (false confession reason), and expert witness testimony vs. defendant explanation vs. expert witness testimony plus defendant explanation for his false confession (source). The four hypotheses and one research question pertained to main effects and interaction effects of false confession presence, false confession reason, and source (separately) and expert witness conditions combined on five outcome variables. Outcome variables were defendant’s guilt, trustworthiness, suggestibility, susceptibility to external influences, and juror’s likelihood of changing their verdict. Using Amazon …

Non-Traditional Church Involvement As A Life-Course Turning Point: Qualitative Interviews With Religious Offenders, William Hunter Holt

Dissertations

This research project conducted and then analyzed qualitative interviews from former and current addicts and criminal offenders who are voluntarily participating in the Christian faith at the same non-traditional, Protestant church. An abridged case study of this church is also provided for background and context. Life-course theory and grounded theory are utilized.

Both the offenders and this church were chosen in an attempt to better understand how the offenders’ involvement at this house of worship, along with their faith in general, have impacted them. Obtaining the perspectives of the offender is essential for three reasons. First, qualitative research conducted in …

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 …

Like Me, Do What I Say, & Think About My Influence: The Effects On Witness Choosing And Metacognition, Brittany Race

Graduate Theses and Dissertations

Confidence can be a strong predictor of accuracy if circumstances are ideal (Wixted & Wells, 2017), but ideal circumstances are not always present. As such it is important to understand ways to ameliorate potentially negative effects on eyewitness metacognition. Rapport building, though seen as an important element of police/witness interaction (Vallano et al., 2015), can lead to some potentially negative memory effects (Wright et al., 2015). Additionally steering, or the process of directing a witness toward a particular suspect, can increase false identifications. Recently the researcher has developed a paradigm meant to better calibrate confidence by reinstating the context of …

Exploring Locus Of Control In Offender Cognition And Recidivism Paradigms, Anistasha Lightning, Danielle Polage

All Master's Theses

Working with four Washington State county jails to administer surveys to currently incarcerated inmates, we investigated locus of control and beliefs in the likelihood of continued legal involvement as possible antecedents to criminal recidivism. The surveys examined whether there was any connection between legal involvement frequency and the externalization of locus of control. We investigated external locus of control with specific respect to involvement with the law, the prospect of future incarceration, and feelings concerning the overall cause of original and/or sustained legal involvement utilizing the Revised Causal Dimension Scale (McAuley, Duncan, & Russell, 1992). We identified statistically significant interactions …

An Analysis And Critique Of Mental Health Treatment In American State Prisons And Proposal For Improved Care, Shelby Hayne

Scripps Senior Theses

Mental health treatment in state prisons is revealed to be highly variable, under-funded, and systematically inadequate. Existing literature exposes this injustice but fails to provide a comprehensive proposal for reform. This paper attempts to fill that gap, outlining a cost-effective, evidence-based treatment proposal, directly addressing the deficits in care revealed through analysis of our current system. In addition, this paper provides historical overviews of the prison system and mental health treatment, utilizing theoretical perspectives to contextualize this proposal in the present state of affairs. Lastly, the evidence is provided to emphasize the potential economic and social benefits of improving mental …

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 …

The Predictors Of Juvenile Recidivism: Testimonies Of Adult Students 18 Years And Older Exiting From Alternative Education, La Toshia Palmer

Dissertations

Purpose: The purpose of this descriptive, qualitative study was to identify and describe the importance of the predictors of juvenile recidivism and the effectiveness of efforts to prevent/avoid juvenile recidivism as perceived by previously detained, arrested, convicted, and/or incarcerated adult students 18 years of age and older exiting from alternative education in Northern California. A second purpose was to explore the types of support provided by alternative schools and the perceived importance of the support to avoid recidivism according to adult students 18 years of age and older exiting from alternative education.

Methodology: This qualitative, descriptive research design identified …

Aspirations Of Objectivity: Systemic Illusions Of Justice In The Biased Courtroom, Meagan B. Roderique

Scripps Senior Theses

Given the ever-growing body of evidence surrounding implicit bias in and beyond the institution of the law, there is an equally growing need for the law to respond to the accurate science of prejudice in its aspiration to objective practice and just decision-making. Examined herein are the existing legal conceptualizations of implicit bias as utilized in the courtroom; implicit bias as peripheral to law and implicit bias as effectual in law, but not without active resolution. These views and the interventional methods, materials, and procedures they inspire are widely employed to appreciably “un-bias” legal actors and civic participants; however, without …

Details In Testimony: How Hedge Words Influence People’S Perceptions Of Victim Testimony Credibility, Justine B. Rayborn

Student Theses

The purpose of this study was to examine whether hedge words and the age of a memory can influence the way participants (mock jurors) perceive an alleged sexual assault victim’s credibility. Prior research has demonstrated many issues that can affect the accuracy of memory for childhood events such as childhood amnesia, fragmented and distorted memories, false memories and source monitoring errors and the way in which jurors’ decisions can be swayed based on verbal cues to confidence. Here, we further investigated whether jurors' decisions are sensitive to the age of the memory—an event that happened in the recent or distant …

Radio Dispatch Cognitive Abilities And Working Memory, David A. Buitron

Electronic Theses, Projects, and Dissertations

Public safety radio dispatchers incontrovertibly have to manage multiple tasks at any given time, from relaying lifesaving information to field units, to simultaneously overseeing several monitors and keeping up with the radio transmissions in a timely manner. Interestingly, however, the underlying cognitive abilities necessitated for performing such tasks have not been thoroughly investigated. To begin understanding the cognitive faculties that underlie dispatching tasks, we gauged cognitive ability measures relevant to dispatcher duties and introduced Working Memory Capacity (WMC) as underlying the differentiation on performance. The four general dispatcher cognitive factors identified by Peace Officer Standards and Training (POST) literature, were …

The Role Of Attention And Memory In Prospective Person Memory, Kara Nicole Moore

Graduate Theses and Dissertations

I examined the role of memory and attention in prospective person memory. Prospective person memory involves being on the lookout for a person with the goal of completing some task (i.e., contacting the authorities) upon encountering the person. Success at prospective person memory tasks in lab and field based studies is rather low (i.e., less than 10% of people report encountering the person). In the current study the prospective person memory task involved a simulated search for a missing person. I manipulated attention to the missing person and strategic monitoring, which involves being in retrieval mode and searching for cues. …

The Influence Of Emotion On Memory For A Crime, Taylor Langley

Electronic Theses and Dissertations

Researchers have reported errors in recall or recognition of witnessed events, accounting for the most common cause of false convictions of innocent people. Tiwari (2010) indicated that 25% of suspects who were identified in a line-up were actually innocent. Jurors are strongly influenced by eyewitness testimony and this can lead to false convictions. The validity of eyewitness identification is critical in cases in which it is used as evidence. In the current study we examined specific emotion states by inducing fear, surprise, and neutral moods. We hypothesized that participants in the Fear group would be least susceptible to the effects …
