Dorsal Striatum Does Not Mediate Feedback-Based, Stimulus-Response Learning: An Event-Related Fmri Study In Patients With Parkinson's Disease Tested On And Off Dopaminergic Therapy, Nole M. Hiebert, Adrian M. Owen, Hooman Ganjavi, Daniel Mendonça, Mary E. Jenkins, Ken N. Seergobin, Penny A. Macdonald

Brain and Mind Institute Researchers' Publications

© 2018 Learning associations between stimuli and responses is essential to everyday life. Dorsal striatum (DS) has long been implicated in stimulus-response learning, though recent results challenge this contention. We have proposed that discrepant findings arise because stimulus-response learning methodology generally confounds learning and response selection processes. In 19 patients with Parkinson's disease (PD) and 18 age-matched controls, we found that dopaminergic therapy decreased the efficiency of stimulus-response learning, with corresponding attenuation of ventral striatum (VS) activation. In contrast, exogenous dopamine improved response selection accuracy related to enhanced DS BOLD signal. Contrasts between PD patients and controls fully support these …

Decision Making, Julia Nolte, David M. N. Garavito, Valerie F. Reyna

Chapters in Books

Choice is ubiquitous, from small decisions such as whether to bring an umbrella to life-changing choices such as whether to get married. Making good decisions is a lifelong challenge. Psychologists have long been fascinated by the mechanisms that underlie human decision making. Why do different people make different decisions when offered the same choices? What are common decision making errors? Which choice option is the “best” and why? These questions are addressed in this chapter.

We first outline models and theories of decision making, defining key concepts and terms. We then describe the psychological processes of decision makers and how …

What Do You Want To Be When You Grow Up? Cognitive Flexibility Influences Career Decision Making And Related Anxiety, Emily Flandermeyer

Undergraduate Honors Thesis Collection

Career indecision is a stage most individuals pass through during their lifetime, but it is often accompanied by anxiety. While anxiety can have a positive influence on decision making by focusing attention and cognitive resources, excess anxiety can disrupt the career decision-making process. Existing literature links anxiety to cognitive flexibility, an individual’s ability to efficiently switch between thoughts and ideas and adapt to evolving situations, with young adults higher in cognitive flexibility typically experiencing less anxiety than their less flexible peers. However, no studies to date have examined cognitive flexibility as it relates to career indecision or career-indecision-related anxiety. This …

Measurement Invariance Of Maximizing Tendency Scales, Paige M. Foss

Legacy Theses & Dissertations (2009 - 2024)

The present research investigated the measurement invariance of two maximizing tendency scales; the Maximizing Scale (MS) and the Maximizing Tendency Scale (MTS), across three cultural and language multigroup comparisons. Archival data from 13 studies were analyzed (N = 6013) using a confirmatory factor analysis (CFA) and an item response theory (IRT) technique. CFA results indicate that both measures are noninvariant at the metric level. IRT results indicated that the MTS had six items that exhibited differential item functioning, but at the test level, expected score differences are small, so researchers may be able to safely use the MTS at the …

Effectiveness Of Hazardous Attitudes Mitigation In Pilot Training, Matthew D. Furedy Ed.D.

National Training Aircraft Symposium (NTAS)

One of the minimum levels of flight training required to fly within the US includes obtaining the necessary skills to acquire a Private Pilot Certificate. Further training requirements are needed depending on whether one desires to operate under Visual Flight Rules (VFR) or Instrument Flight Rules (IFR). It has been stated by the FAA that Aeronautical Decision Making (ADM) training for pilots has been effective in reducing in-flight errors by up to 50 percent. Hazardous attitudes and their associated antidotes are currently discussed as part of the FAA’s ADM training for pilots. The purpose of this study is to add …

Effects Of Emotion And Social Desirability On Intuitive, Gist-Based Decisions, Wyn E. Taylor

Psychology Dissertations

People often make what appear to be inconsistent, irrational choice preference shifts from sure-to-risky (or from risky-to-sure) options depending on how the choices are framed—this is a form of decision bias called the framing effect. Given numerically identical outcome options, a consistent preference for risky choices or for sure choices is viewed in decision theory as a rational choice. Fuzzy Trace Theory suggests that framing effects are the result of gist processes. However, social desirability characteristics of the choices and individuals’ concern for social approval could explain framing effects. The current study compared susceptibility to the framing effect in three …

Examining The Effects Of Framing On Probability Discounting, Owen M. Chevalier

Undergraduate Honours Theses

Probability discounting is the process by which people choose a smaller, more-likely reward instead of a larger, less-likely reward (McKerchar & Renda, 2012). While this phenomenon has been well documented, very few studies have tested discounting experimentally using real money. The present experiment was designed to remedy this by replicating a study by Weatherly and Derenne (2013) which showed that undergraduate students discounted money they believed they had won more than money they believed they were owed. 27 undergraduate students were asked to either complete a simple cognitive task or roll a die. The participants in the owed condition were …

[Introduction To] Well-Grounded: The Neurobiology Of Rational Decisions, Kelly Lambert

Bookshelf

Contingency calculations—the ability to predict the outcomes of decisions and actions—are critical for survival and success. Our amazing brains continually process past and current experiences to enable us to make the most adaptive choices. But when the brain’s information systems are compromised—by such varying conditions as drug addiction, poverty, mental illness, or even privilege—we can lose the ability to arrive at informed decisions.

In this engaging book, behavioral neuroscientist Kelly Lambert explores a variety of the modern factors that can lead to warped neural processing, or distorted realities she terms “brain bubbles.” Individuals who define success in terms of creature …

The Effects Of Repeated Lineups And Delay On Eyewitness Identification, Wenbo Lin

Arts & Sciences Electronic Theses and Dissertations

Prior eyewitness research has examined the effects of repeated identification procedures and delays on eyewitness identification, but these studies have either confounded these two factors or studied them in isolation. Experiment 1 attempted to disentangle these factors through systematic manipulations of the number of repeated lineups and the length of delay between the original event and the first lineup. Experiment 2 examined whether the length of delay between two lineups (Lineups 1 and 2) affects the subsequent lineup identification decisions. We found that people were more inclined to choose when a lineup was repeated. A longer delay between the crime …

Goats Favour Personal Over Social Information In An Experimental Foraging Task, Luigi Baciadonna, Alan G. Mcelligott, Elodie F. Briefer

Alan G. McElligott, PhD

Animals can use their environments more efficiently by selecting particular sources of information (personal or social), according to specific situations. Group-living animals may benefit from gaining information based on the behaviour of other individuals. Indeed, social information is assumed to be faster and less costly to use than personal information, thus increasing foraging efficiency. However, when food sources change seasonally or are randomly distributed, individual information may become more reliable than social information. The aim of this study was to test the use of conflicting personal versus social information in goats (Capra hircus), in a foraging task.We found that goats …

Alternative Measures Of Noncognitive Skills And Their Effect On Retirement Preparation And Financial Capability, Gema Zamarro

Education Reform Faculty and Graduate Students Publications

Social science, more than ever, is drawing upon the insights of personality psychology. Though researchers now know that noncognitive skills and personality traits, such as conscientiousness, grit, self-control, or a growth mindset could be important for life outcomes, they struggle to find reliable measures of these skills. Self-reports are often used for analysis, but these measures have been found to be affected by important biases. We study the validity of innovative, more robust measures of noncognitive skills based on performance tasks. Our first proposed measure is an adaptation, for the adult population, of the Academic Diligence Task (ADT) developed and …

A Preliminary Comparison Of Pilots' Weather Minimums And Actual Decision-Making, Nathan W. Walters, Mattie Milner, Daniel A. Marte, Evan A. Adkins, Marie Aidonidis, Matt B. Pierce, Abigail K. Pasmore, Angela Roccasecca, Stephen Rice, Scott R. Winter

National Training Aircraft Symposium (NTAS)

Adverse weather conditions remain a leading contributing factor in general aviation accidents. In compromising situations, such as severe weather, pilots continue to make decisions, which endanger themselves, passengers, and the aircraft. Although technology and training have lowered the risks associated with poor decision making by aviators, they are often still faced with scenarios requiring split second judgments. A countermeasure to these risks is the use of personal weather minimums by pilots. The purpose of this study was to examine pilot’s decision-making and performance, while flying an instrument approach, under extreme conditions of low visibility and ceiling as based on their …

Assessing The Impact Of Pain On Decision-Making In A Rat Gambling Task (Rgt), Celina Antionette Salcido

Psychology Theses

Recent clinical assessments using the Iowa Gambling Task have revealed pain can negatively affect decision-making processes, leading to risky or poor decisions. Despite the gain these models have made in further elucidating the cognitive components of pain, they fail to fully address neurobiological factors of decision-making on behavior. As a result, there remains significant limitation in assessing the extent of how acute or chronic pain and the relief of pain with analgesics can affect cognitive abilities. Therefore, we examined the effect of acute and chronic pain on decision processing and the impact of morphine on that decision processing. In this …

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 …

Cognition And Commerce: The Impact Of Intuitive Judgment And Rational Analysis On Business Decisions, Bridget A. Bicknell

Undergraduate Honours Theses

Decision makers who evaluate complex alternatives in real-world decision-making contexts are susceptible to cognitive biases, which can influence judgments, and may result in irrational decisions. Engaging in deliberate, systematic evaluation may reduce the extent to which biases pervade rational judgments (Kahneman, 2011). Previous studies have demonstrated that the deliberate consideration of multiple alternatives is an effective strategy to reduce biases (Lord, Lepper, & Preston, 1984). However, there is limited research on the effects of deliberate analysis on judgments in business decision-making. The present study examines whether the extent of deliberate analysis would elicit differences in the degree to which judgments …

The Effects Of Delay And Probabilistic Discounting On Green Consumerism, Blake J. Bent

Psychology Theses & Dissertations

People have a tendency to discount outcomes that are delayed or probabilistic. In other words, people will sacrifice larger benefits for smaller benefits that are immediate or certain. For many environmentally-friendly (“green”) products, the financial benefits are both delayed and probabilistic. The current study examined how delay and probability, as well as frame and magnitude, influenced consumers’ decisions when comparing a conventional and green product. Participants were recruited from Amazon’s Mechanical Turk and completed one of two experiments. In each experiment participants chose between a conventional product (low initial cost, high operating cost) and green product (high initial cost, low …

Thiamine Deficiency And Alcohol Exposure Both Lead To An Impulsive Phenotype, Robin J. Zimmer

Graduate Dissertations and Theses

The detrimental effects of alcohol consumption, including impulsivity, cognitive inflexibility, and neuropathology, are due to a confluence of factors that often occur in addition to alcoholism. We examined the effects of chronic alcohol exposure and thiamine deficiency (or supplementation) in isolation, as well as in concert, to further our understanding of the independent effects of each treatment and how they interact. Our results demonstrated that both chronic alcohol exposure and moderate thiamine deficiency induce an impulsive phenotype. Importantly, the increased impulsivity induced by thiamine deficiency was protracted as compared to that exhibited after chronic alcohol alone. Additionally, differential pathology was …

Goats Favour Personal Over Social Information In An Experimental Foraging Task, Luigi Baciadonna, Alan G. Mcelligott, Elodie F. Briefer

Anxiety Sensitivity And Decision Making: Positive And Negative Risk Taking In Laboratory And Naturalistic Settings, Amanda Kutz

Electronic Theses and Dissertations

As a group, anxiety disorders represent the most prevalent mental health condition. A hallmark feature of anxiety disorders is avoidant behavior. Along with this, anxious individuals have been shown to exhibit a risk aversion in decision making. However, anxiety disorders are simultaneously highly co-morbid with substance use disorders (e.g., Grant, Stinson, Dawson, & Chou, 2004), suggesting that certain individuals with anxiety disorders engage in particular forms of risk taking. However, much of the current literature on anxiety and risk taking has focused on risk aversion in anxiety, presupposing an inhibited model of anxious responding. In addition, there is little literature …

Decision Making In Older Adults: A Comparison Of Delay And Probability Discounting Across, Ariana Vanderveldt

Arts & Sciences Electronic Theses and Dissertations

The value of an outcome is affected both by the delay until its receipt (delay discounting) and by the likelihood of its receipt (probability discounting). The discounting framework has greatly aided in modeling and understanding decision-making, particularly in the areas of impulsivity, but these findings have overwhelmingly been based on research with young adults. In three experiments, the current study extended the discounting framework by examining choice by older adults. Experiments 1 and 2 found that both young and older adults discounted delayed outcomes and probabilistic outcomes and that their choices were well-described by the same hyperboloid model. Both young …

Understanding The Determinants Of Parental Decision-Making And Harsh Parenting Behavior, Ralitsa Stoyneva Maduro

Psychology Theses & Dissertations

The high prevalence and negative consequences of hash parenting among US parents is well-documented. However, intervention and prevention efforts aimed at reducing the rates of harsh parenting have had limited success. A goal of this paper was to provide a novel method of studying parenting behavior; moving beyond correlational findings. Specifically, I argued that preventing harsh parenting has been a challenge, in part because of lack of understanding of the decision-making processes underlying the behavior. In an effort to incorporate tradition decision making methodology, I designed a between subjects, single-blind, randomized experiment. The experimental manipulations were design to induced emotional …

Creating A More Ecologically Valid Decision Task, Kevin L. Kenney

Master's Theses

There has been a standing debate in the field regarding the effectiveness of frequencies and probabilities to accurately convey information. This study utilized a naturalistic sampling procedure to determine risk preferences on binary choice decision using time, sex, and goal deficit variables as predictors. Participants consisted of 110 undergraduate students enrolled in core psychology courses at Fort Hays State University. A web application was created to conduct this specific study that will be made available to other researchers. Significant effects existed for time and goal deficit variables that predicted risk preferences.

Sidestepping The Rock And The Hard Place: The Private Avoidance Of Prosocial Requests, Stephanie C. Lin, Rebecca L. Schaumberg, Taly Reich

Research Collection Lee Kong Chian School Of Business

For some, facing a prosocial request feels like being trapped between a rock and a hard place, requiring either a resource (e.g., money) or psychological (e.g., self-reproach) cost. Because both outcomes are dissatisfying, we propose that these people are motivated to avoid prosocial requests, even when they face these requests in private, anonymous contexts. In two experiments, in which participants' anonymity and privacy was assured, participants avoided facing prosocial requests and were willing to do so at a personal cost. This was true both for people who would have otherwise complied with the request and those who would have otherwise …

Should I Stand By Or Stand Up? Differences In Bullying Bystander Decision Making, Lyndsay Masters

Electronic Thesis and Dissertation Repository

Over 80% of students have been a bystander to bullying at school. Bystanders who witness bullying may choose to “stand up” against the bully and support the victim personally, encourage intervention from peers or adults, join in with the bullying or “stand by” passively without involvement. These decisions may be influenced by a variety of personal, social and environmental factors. This study proposes that bullying bystanders differ across specific factors according to their decision to intervene or not intervene. Archived data from a culturally-representative sample of 482 middle-school students were used and analyzed from a person-oriented approach. Data represented the …

Creativity In Organizations: Antecedents And Outcomes Of Individual Creativity, Goran Calic

Open Access Dissertations

In this dissertation I set out to expand our collective understanding of creativity in organizations. I accomplish this through three related studies, each organized into independent chapters of this dissertation.

The first study explores how demands of organizations, particularly strategic contradictions faced by decision makers, affect creative processes and products. In this chapter I develop the theory of paradoxical creativity, which posits that creative discovery is a function of how strategic contradictions are perceived by decision-makers. The key insight of the theory of paradoxical creativity is that strategic contradictions have independent effects on the two stages of creative discovery (generation …

Acute Stress Exposure And Expression Of Instrumentally Conditioned Financial Preferences: An Fmri Study, William Travis Mccuddy

Master's Theses (2009 -)

Recent research suggests acute stress exposure is associated with increased habit-based over goal-oriented decision making (e.g., Schwabe & Wolf, 2011). The current study examined whether acute stress promotes the expression of simple financial preferences “overtrained” to the point of habit in the face of a changing environment where said preferences were later rendered non-optimal. Over three days participants (N = 28) learned to discriminate between visual stimuli probabilistically associated with monetary gains or losses and made decisions between stimuli with real financial outcomes. On the fourth day after exposure to either an acute stressor or control procedure participants performed the …

On The Meaning And Measurement Of Maximization, Nathan Norem Cheek , '15, Barry Schwartz

Psychology Faculty Works

Building on Herbert Simon’s critique of rational choice theory, Schwartz et al. (2002) proposed that when making choices, some individuals — maximizers — search extensively through many alternatives with the goal of making the best choice, whereas others — satisficers — search only until they identify an option that meets their standards, which they then choose. They developed the Maximization Scale (MS) to measure individual differences in maximization, and a substantial amount of research has now examined maximization using the MS, painting a picture of maximizers that is generally negative. Recently, however, several researchers have criticized the MS, and almost …

The Technology Effect: How Perceptions Of Technology Drive Excessive Optimism, Brent B. Clark, Christopher Robert, Stephen A. Hampton

Marketing and Management Faculty Publications

Purpose: We propose that constant exposure to advances in technology has resulted in an implicit association between technology and success that has conditioned decision makers to be overly optimistic about the potential for technology to drive successful outcomes. Three studies examine this phenomenon and explore the boundaries of this “technology effect.”

Design/Methodology/Approach: In Study 1, participants (N = 147) made simulated investment decisions where the information about technology was systematically varied. In Study 2 (N = 143), participants made decisions in a resource dilemma where technology was implicated in determining the amount of a resource available for harvest. Study 3 …
