Improving The Accuracy Of Juror Self-Reports Of Bias During Rehabilitative Voir Dire, Natalie Gordon

Dissertations, Theses, and Capstone Projects

The courts have long acknowledged pretrial publicity (PTP) as a source of juror bias. To safeguard defendants due process rights, jurors who harbor bias are frequently asked during voir dire if they can set aside their bias and be fair and impartial. Yet, jurors’ self-reports of their ability to be fair and impartial are largely inaccurate. For example, regardless of their level of exposure to PTP, jurors typically report an ability to be fair and impartial. Therefore, this method of so-called “juror rehabilitation” is ineffective. This project examines conformity pressures that may be inhibiting accurate self-reporting during juror rehabilitation and …

How To Make Critical Decisions Amid Covid-19 Pressures, David Chan

Research Collection School of Social Sciences

Time pressure and ambivalence are common when people make decisions in a crisis. Understanding the psychological dynamics helps us slow down to make better decisions.

An Investigation Of “Actual” Versus “Perceived” Substance Use Among College Students, Jordan Ragland

Senior Theses and Projects

Alcohol and illicit substance use is recognized as a widespread public health concern across college campuses in the United States (Shepard Meteyer, Bruzios, Pol, & Charpentier 2017). Perceived norms are among the strongest predictors of college student alcohol use and related problems (Ecker, Cohen, & Buckner 2017). Prior research has shown that normative perceptions relate to one’s own drinking behavior (Lewis, Litt, Blayney, Lostutter, Granato, Kilmer, & Lee 2011). This data has shown that college students typically overestimate the amount other students or peers drink. Based on previous literature this can be applied to drug, marijuana, and nicotine use. The …

Diversity Team Building: Impact On Virtual Team Performance, Nina C. Magpili-Smith

Engineering Management & Systems Engineering Theses & Dissertations

Although organizations have addressed diversity issues at the organizational-level with resulting positive employee outcomes, lack of scholarly attention to team-level interventions remain. Team-level interventions would benefit organizations more directly as they address issues directly related to task accomplishment. Since diversity may lead to negative performance results for teams, a team building intervention based on the latest empirical research was developed and tested to address the potential performance losses associated to diversity in decision-making teams. The team building intervention provides six crucial elements, namely (1) direct experience of how deep-level team diversity affect team dynamics, (2) diversity education, (3) cultivation of …

Hindsight Bias In Clinical Decision Making, Amanda Beltrani

Student Theses

The tendency for an individual to believe that a specific event, in hindsight, was more predictable than it was in foresight is known as hindsight bias. This phenomenon has been demonstrated in the psychological literature across a variety of samples, methodologies, and predictions for decades. The current study used a sample of 95 mental health professionals to explore the impact of advanced outcome knowledge on the decision making process. Participants reviewed a hypothetical risk assessment in the form of a hospital chart and then responded to a series of questions, using only their clinical judgment. Analyses revealed that evaluators who …

Moral Traps: When Self-Serving Attributions Backfire In Prosocial Behavior, Stephanie C. Lin, Julian J. Zlatev, Dale T. Miller

Research Collection Lee Kong Chian School Of Business

Two assumptions guide the current research. First, people's desire to see themselves as moral disposes them to make attributions that enhance or protect their moral self-image: When approached with a prosocial request, people are inclined to attribute their own noncompliance to external factors, while attributing their own compliance to internal factors. Second, these attributions can backfire when put to a material test. Studies 1 and 2 demonstrate that people who attribute their refusal of a prosocial request to an external factor (e.g., having an appointment), but then have that excuse removed, are more likely to engage in prosocial behavior than …

Does Ego-Depletion Impair The Ability To Identify A Self-Control Conflict?, Jeffrey M. Osgood

Legacy Theses & Dissertations (2009 - 2024)

Research from the past fifteen years suggests that strong exertions of self-control in one instance cause self-control failure in subsequent instances. This phenomenon is called the “ego-depletion effect”. More recently, new theoretical and empirical advances in self-control research suggest a Two-Stage Model of self-control. During Stage One, individuals must identify the need to use self-control by recognizing a conflict between their current behavior and long-term goals, values, or social standards. In Stage Two, individuals must implement self-control strategies or willpower to bring current behavior in line with long-term goals, values, or social standards. To date, ego-depletion research has focused mostly …

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 …

On Getting Better And Working Hard: Using Improvement As A Heuristic For Judging Effort, Monica El Gamal

Theses and Dissertations (Comprehensive)

There is a strong conceptual association between improvement and effort. Therefore, we propose that people tend to use improvement as a heuristic for judging effort in others. Hence, they would perceive greater effort in improved performance records than in non-improved records with superior overall performance. To examine whether people use improvement as a heuristic for effort, we compared judgments of effort investments and trait effort in improved and consistently-strong performance profiles with equivalent recent performance. Across six empirical studies, participants thought that those with improved profiles exerted more effort and were more hardworking than those with consistently-strong profiles, and this …

The Role Of Emotion In Environmental Decision Making, Hannah Dietrich

Department of Psychology: Dissertations, Theses, and Student Research

Given the environmental concerns of our planet, it is imperative to consider issues of environmental sustainability. Researchers argue that the most serious environmental problems are not merely issues of science, but that of individual behavior. Solutions, therefore, must consider the role of the individual—how one can change his/her behaviors to be more environmentally conscious. The experience of negative or positive emotions, may impact not only people’s experiences with the environment, but also their tendency to engage in pro-environmental behavior. The present study sought to experimentally investigate the role of emotion and information on pro-environmental behavior change. Results indicate that neither …

Understanding How Deciding And Relationship Confidence Predict Relationship Satisfaction, Elise M. Yoshida

CMC Senior Theses

This study examines how gender, deciding, and relationship confidence predict romantic relationship satisfaction using the Relationship Deciding Scale (Vennum & Fincham, 2011). Deciding refers to the thoughtfulness regarding the decisions made in and about relationships. Relationship confidence is the confidence a person has toward their ability to maintain a healthy relationship and handle conflicts in the relationship. Using an online survey, participants (age range: 18-22 years) answered questions about relationship confidence, deciding, and relationship satisfaction. They rated relationship satisfaction using their most recent relationship, so single people were included in the study. Multiple regression determined that deciding and relationship confidence …

Uncertainty And Information Processing, Robert E. Frost Iii

Masters Theses & Specialist Projects

The purpose of these two studies was to examine two factors that may influence the effects of uncertainty on information processing. The first factor is the positioning of uncertainty relative to a target of judgment, and how this affects people’s judgment processing. The second factor had to do with the degree to which uncertainty signals active goal conflict or not. In the first study, 145 participants with a mean age of 19.51 were induced with uncertainty either before or after information about the target accused of illegal behavior. The results demonstrated that uncertainty before information produced higher guilt judgments of …

Development Of Response Evaluation And Decision (Red) And Antisocial Behavior In Childhood And Adolescence, Reid Griffith Fontaine, Chongming Yang, Kenneth A. Dodge, Gregory S. Pettit, John E. Bates

Reid G. Fontaine

Using longitudinal data on 585 youths (48% female; 17% African American, 2% other ethnic minority), the authors examined the development of social response evaluation and decision (RED) across childhood (Study 1; kindergarten through Grade 3) and adolescence (Study 2; Grades 8 and 11). Participants completed hypothetical-vignette-based RED assessments, and their antisocial behaviors were measured by multiple raters. Structural equation modeling and linear growth analyses indicated that children differentiate alternative responses by Grade 3, but these RED responses were not consistently related to antisocial behavior. Adolescent analyses provided support for a model of multiple evaluative domains of RED and showed strong …

Knowing When To Trust Others: An Erp Study Of Decision-Making After Receiving Information From Unknown People, Cheryl Boudreau, Mathew D. Mccubbins, Seana Coulson

Faculty Scholarship

To address the neurocognitive mechanisms that underlie choices made after receiving information from an anonymous individual, reaction times (Experiment 1) and event-related brain potentials (Experiment 2) were recorded as participants played 3 variants of the Coin Toss game. In this game, participants guess the outcomes of unseen coin tosses after a person in another room (dubbed “the reporter”) observes the coin toss outcomes and then sends reports (which may or may not be truthful) to participants about whether the coins landed on heads or tails. Participants knew that the reporter's interests either were aligned with their own (Common Interests), opposed …

Nothing But The Truth? Experiments On Adversarial Competition, Expert Testimony, And Decision Making, Cheryl Boudreau, Mathew D. Mccubbins

Faculty Scholarship

Many scholars debate whether a competition between experts in legal, political, or economic contexts elicits truthful information and, in turn, enables people to make informed decisions. Thus, we analyze experimentally the conditions under which competition between experts induces the experts to make truthful statements and enables jurors listening to these statements to improve their decisions. Our results demonstrate that, contrary to game theoretic predictions and contrary to critics of our adversarial legal system, competition induces enough truth telling to allow jurors to improve their decisions. Then, when we impose additional institutions (such as penalties for lying or the threat of …

Effective Group Meetings And Decision Making, Donelson R. Forsyth

Jepson School of Leadership Studies articles, book chapters and other publications

Single individuals do much to advance the cause of peace, but much of the work - the decisions, advocacy, planning, and organizing - is handled by groups. In groups we pool our knowledge and abilities, give each other feedback, and tackle problems too overwhelming to face alone. Group members give us emotional and social support and can stimulate us to become more creative, insightful, and committed to our goals. When we work with others who share our values and goals, we often come to understand ourselves, and our objectives, more clearly.

Not every group, however, realizes these positive consequences. Often …

An Empirical Analysis Of The Effect Of The Need For Closure On Materiality Thresholds Of Auditors, Cynthia M. Daily

Doctoral Dissertations

The purpose of this study is to identify the strengths of a specific motivator for judgment and decision-making, referred to as “need for closure” and determine how the strength of that motivator affects materiality judgments of auditors.

The extent to which auditors seek and process information prior to forming a judgment can have important consequences in the conduct of an audit. In this regard, psychology researchers have identified a personality characteristic—a motive for judgment and decision making—that influences the decision making process. This motive, referred to as the need for closure, pertains to the desire of individuals to clear …

Relocation Decision-Making In Dual-Career Couples, Lori Bartels

Psychology Theses & Dissertations

This study examined the decision-making process of individuals in dual-career couples when faced with a job opportunity in a distant city. The purpose was to determine which factors would be given the most importance by males and females during the decision process.

Each scenario presented an identical situation in which the participant was offered a job in a distant city. Following this paragraph were five brief statements representing five factors; job opportunities for self, job opportunities for spouse, career commitment--self, career commitment--spouse, and economic considerations. Two levels (moderate and high) of each factor were used in order to manipulate the …

Closedmindedness As A Predictor Of Individual Decision-Making Behaviors, Annette I. Jolin

Dissertations and Theses

The purpose of this study was to examine whether closemindedness is related to decision-making behaviors. The decision-making variables in this study were: Pieces of Information, Decision Change, Decision Confidence, Decision Accuracy and, post hoc, Decision Appropriateness. The measures of decision-making behaviors were obtained from four decision situations developed by the experimenter. Closemindedness was assessed using Rokeach's (1960) Dogmatism (D) scale.
