Humans Integrate Monetary And Liquid Incentives To Motivate Cognitive Task Performance, Debbie Yee

Arts & Sciences Electronic Theses and Dissertations

It is unequivocal that a wide variety of incentives can motivate behavior. However, few studies have explicitly examined whether and how different incentives are integrated in terms of their motivational influence. The current study examines the combined effects of monetary and liquid incentives on cognitive processing, and whether appetitive and aversive incentives have distinct influences. We introduce a novel task paradigm, in which participants perform cued task-switching for monetary rewards that vary parametrically across trials, with liquid incentives serving as post-trial performance feedback. Critically, the symbolic meaning of the liquid was held constant (indicating successful reward attainment), while liquid valence …

Incentive Contrast As A Relative Reward, Alexandra Schmidt

Honors Projects

This study examines the relationship between rapid relative reward comparisons and incentive contrast among rats (n=5). Animals were trained to lever-press in order to obtain access to a sucrose solution (concentration used: 1%, 10% or 20% in tap water). These rewards were placed outside an operant box which could be reached through a small hole displaying sessions with mixed comparisons (1v20%, 20v1%) or single sessions (1v1%, 10v10%, 20v20%) that rotated between two spouts containing the pre-randomized order of paired blocks; allowing for comparative analysis between two spouts/concentrations and blocks of responses. Throughout weekly testing each animal experienced a …

Dispositional Employability And The Relationship To Career Success: A Meta-Analysis, Alisha M. Jasmer

Electronic Theses, Projects, and Dissertations

This meta-analysis focuses on the willingness to work aspect of the RAW model of employability of Hogan et al. (2009), in relationship to career success. Willingness to work (W) can be defined as favorably disposed to work hard and take initiative at one’s job. The variables I used to structure the W are proactive personality, conscientiousness, work ethic, job involvement, adaptability, and ambition.

I used the Hunter and Schmidt method to analyze the data applying a random effects model. All calculations were conducted in Excel. The overall sample consisted of 100 effect sizes (r) derived from 41 studies. The total …

The Effect Of Motivation And Positive Affect On Ego Depletion: Replenishment Versus Release Mechanism, Ze Zhu, Jian Li, Bo Zhang, Ye Li, Houcan Zhang

Psychology Faculty Publications

In this study, 2 experiments were conducted to investigate whether motivation and positive affect can alleviate ego depletion and to elucidate their possible mechanisms. In Experiment 1, a crossing-out-letter task was adapted to reach an ego depletion state for Chinese participants. Participants were then randomly assigned to the extrinsic motivation group, the positive affect group or the depletion control group. After the experimental treatment, a dumbbell task was used to measure participants' remaining self-regulatory resources. The results showed that participants in the motivation and positive affect groups performed better on the dumbbell task than participants in the depletion control group. …

I Knew It All Along, Unless I Had To Work To Learn What I Know, Harry Wallace, Michelle Chang, Patrick Carroll, Jodi Grace

Harry M. Wallace

After receiving knowledge regarding some topic, people usually overestimate their prior topic knowledge. Two experiments investigated whether people would claim less prior knowledge if they worked to earn their present knowledge. In Study 1, students finishing a psychology course claimed less precourse psychology knowledge if they reported devoting more effort toward the course. In Study 2, the knew-it-all-along effect was stronger for participants who were simply given the answers to questions than for participants who studied for 20 minutes to learn the answers. Both cognitive and motivational factors can account for the observed effects of effort investment on retrospective knowledge …

The Performance Of Narcissists Rises And Falls With Perceived Opportunity For Glory, Harry Wallace, Roy Baumeister

Harry M. Wallace

Narcissists consider themselves to be exceptional performers, but past research has found no consistent relationship between narcissism and performance. The present research tested the hypothesis that the relationship between subclinical narcissism and performance is moderated by a motivational factor: perceived self-enhancement opportunity. Four experiments were conducted, each using different manipulations of self-enhancement opportunity and different performance tasks. In each study, narcissists performed better when self-enhancement opportunity was high rather than low. In contrast, the performance of participants with low narcissism was relatively unaffected by self-enhancement opportunity. Other findings suggested that narcissists' self-enhancement motivation stems more from a desire to garner …

The Effects Of Intrinsic And Extrinsic Sources Of Motivation On Well-Being Depend On Time Of Day: The Moderating Effects Of Workday Accumulation, Alison Benedetti, James Diefendorff, Allison Gabriel, Megan Chandler

James M. Diefendorff

Using self-determination theory and research on temporal aspects of work (e.g., time of day), this study investigates dynamic effects of task-specific motivation on well-being throughout the workday. We argue that the effects of task-specific intrinsic and extrinsic motivations on well-being outcomes (psychological vitality, job satisfaction) depend on the time of day in which the task is encountered, referred to here as workday accumulation. Our results showed that time of day interacted with intrinsic sources of motivation to predict job satisfaction, such that the relation was strong and positive early in the day and weak and positive later in the day. …

Improving Lawyers’ Judgment: Is Mediation Training De-Biasing?, Douglas N. Frenkel, James H. Stark

All Faculty Scholarship

When people are placed in a partisan role or otherwise have an objective they seek to accomplish, they are prone to pervasive cognitive and motivational biases. These judgmental distortions can affect what people believe and wish to find out, the predictions they make, the strategic decisions they employ, and what they think is fair. A classic example is confirmation bias, which can cause its victims to seek and interpret information in ways that are consistent with their pre-existing views or the goals they aim to achieve. Studies consistently show that experts as well as laypeople are prone to such biases, …

Social Networking Website Use And Eating Pathology: Relations, Moderators, And Motivation To Improve, Michelle S. St. Paul

Arts & Sciences Electronic Theses and Dissertations

Social networking website (SNW) use has been found to be associated with decreased body image or esteem and increased eating disorder (ED) symptoms. In turn, SNW use may also be associated with decreased motivation to improve body image (BI) and reduced self-efficacy in one’s ability to do so. However, the impact of SNW use on motivation or self-efficacy to improve BI has not yet been studied. Also, particular moderators of the relationships between SNW and eating pathology have not yet been evaluated. This study aimed to: 1) replicate past literature by examining the relation between SNW use and eating pathology, …

Motivation And Well-Being: A Test Of Self-Determination Theory Using A Person-Centered Approach, Chelsea A. Vaters

Electronic Thesis and Dissertation Repository

Self-determination theory postulates that individuals can experience motivation in different ways and that these different types of motivation fall along a continuum from controlled to autonomous regulation. Recently, there have been challenges to the notion that an individual’s motivation can be categorized as falling at a particular point along the autonomy continuum. Researchers have begun to investigate the possibility that individuals can experience different types of motivation simultaneously. The current study used a person-centered approach to study motivation and also examined how the profiles detected related to well-being outcomes and adaptive student behaviours. Latent profile analyses of data from two …

Psychosocial Motivators For Obstacle Course Racing: A Qualitative Case Study, Aracely Rodriguez

Master's Theses

This study explored the psychological and sociological motivations of adult female and male obstacle course racers. A qualitative case study approach was used to explore the views, experiences, and motivations of obstacle course racing (OCR) participants. Descriptive statistics and cross tabulation was used to interpret responses to the 297 online questionnaires. A content analysis approach was used to analyze the qualitative data gathered from three focus groups with a total of 20 obstacle course racers. Three theories formed the basis of the study: Self-Determination Theory (SDT), Achievement Goal Theory (AGT), and Social Leaning Theory (SLT). Overall, findings supported previous research …

Effects Of Altering Motivation In Pigeons Performing A Titrating-Delayed-Matching-To-Sample Task, Zachary J. Zimmermann

Masters Theses

In order to better understand the role motivating operations (MOs) serve in preceding and evoking behavior, it is useful to examine the effects of whether manipulating motivation can influence performance on tasks with known behavioral outcomes. It is well established that altered stimulus control is responsible for changes in responding on tasks of generalization and discrimination. Therefore, if stimulus control could be influenced by MOs, then perhaps stimulus discriminations could be improved by manipulating the relevant MO. To this end, the effects of altering motivation via food deprivation were examined in pigeons using a titrating-delayed-matching-to-sample task. Additional pharmacological variables (i.e., …

Relative Reward Effects On Operant Behavior: Incentive Contrast,Induction And Variety Effects, Howard Cromwell

Howard Casey Cromwell

Comparing different rewards automatically produces dynamic relative outcome effects on behavior. Eachnew outcome exposure is to an updated version evaluated relative to alternatives. Relative reward effectsinclude incentive contrast, positive induction and variety effects. The present study utilized a novelbehavioral design to examine relative reward effects on a chain of operant behavior using auditory cues.Incentive contrast is the most often examined effect and focuses on increases or decreases in behavioralperformance after value upshifts (positive) or downshifts (negative) relative to another outcome. Weexamined the impact of comparing two reward outcomes in a repeated measures design with three ses-sions: a single outcome and …

Hiv-1 And Cocaine: Motivation And Synaptic Function, Sarah J. Bertrand

Theses and Dissertations

Molecular and behavioral assays were used to examine the effects of HIV-1 on synaptodendritic integrity, motivated behavior and the therapeutic potential of natural isoflavones in ameliorating both synaptodendritic injury in vitro and changes in motivation in vivo. The overarching hypothesis of the present dissertation is twofold: 1. HIV-1 causes a decrease in motivation for sucrose and cocaine and the change in motivational state is driven by compromised synaptic integrity as evaluated by F-actin and DAT function and, 2. Treatment with phytoestrogens will prevent synaptodendritic damage, normalize the internal motivational state of the HIV-1 Tg rat for sucrose and cocaine, and …

Extending An Irt Mixture Model To Detect Random Responders On Non-Cognitive Polytomously Scored Assessments, Mandalyn R. Swanson

Dissertations, 2014-2019

This study represents an attempt to distinguish two classes of examinees – random responders and valid responders – on non-cognitive assessments in low-stakes testing. The majority of existing literature regarding the detection of random responders in low-stakes settings exists in regard to cognitive tests that are dichotomously scored. However, evidence suggests that random responding occurs on non-cognitive assessments, and as with cognitive measures, the data derived from such measures are used to inform practice. Thus, a threat to test score validity exists if examinees’ response selections do not accurately reflect their underlying level on the construct being assessed. As with …

Contrasting Perceptions Of Motivation To Change: Clinicians And Substance Abuse Clients, Arthur Tabrizi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Substance abuse persists as one of the most costly, prevalent, and damaging health problems in the United States. As of 2012, an estimated 22 million individuals, approximately 8.9 percent of the total population, were diagnosed with substance abuse or dependence disorder. Considering the significant number of clients served, successful national completion rates among individuals utilizing outpatient care remain markedly low. In the state of Nevada, where the present study is conducted, successful intensive outpatient treatment (IOP) completion rate remains at an alarmingly low 20.1 percent. Early dropout is a particular concern in that duration of participation in treatment has been …

College Students’ Alcohol Use And Related Problems: What Makes Religiousness A Protective Factor?, Corey Todd Brawner

Master's Theses

Excessive alcohol use has been recognized as a critical health hazard for college students, particularly for members of social fraternities and sororities. Religiousness and Spirituality (R/S) has received substantial support as a protective factor for alcohol use across many populations. The current study utilized a series of hierarchical regression models to delineate the protective influences of six R/S dimensions on alcohol consumption, harmful drinking patterns, and alcohol-related problems, as well as their moderating effect on the association between Greek membership and alcohol outcomes in a sample of 709 undergraduates from one Christian-affiliated institution and one public university. Public religious participation …

Power To The People: A Comprehensive Look At Crowdsourcing Initiatives In Cultural Institutions, Danielle Pace

Seton Hall University Dissertations and Theses (ETDs)

Today, crowdsourcing has become an integrative approach to completing projects using the help of the general populous. These projects aid museum staff by processing large quantities of data, which otherwise could not be completed due to time and/or staff restraints. Through crowdsourcing, cultural institutions have the ability to outsource these tasks to volunteers, who can complete them at much faster rates. Although staff members are needed to validate and supervise these projects, crowdsourcing remains a useful tool in increasing public interactions and project efficiency.

This thesis presents a thorough outline of what crowdsourcing is, how it is being utilized, and …

Anxiety Sensitivity, Stress, And Problematic Drinking Behaviors Among College Students, Kathryn V. Bulandr

Honors Projects

The current study examined whether the combination of anxiety sensitivity (AS) and stress affected college students’ urge and motive to drink alcohol. Participants (n= 95, 44.2% male, 55.8% female, M_age= 18.82 years) included undergraduate students from Illinois Wesleyan University. Participants were asked to fill out a series of questionnaires, in addition to a short anagram task, which was used to induce stress in half of the sample. A multivariate factorial analysis was used to examine two main effects (AS and stress levels) and one interaction effect. Our hypothesis was partially supported, in that there was only …

Motivation, Marital Quality, Maternal Gatekeeping, Breadwinning, And Father Identity: Models Of Biological Fathers’ And Stepfathers’ Involvement In Childcare, Jessica E. Ladage

Psychology Theses & Dissertations

Compared to biological fathers, there is far less knowledge about stepfathers in reference to their involvement in childcare. As stepfathers continue to increase in number in the United States, it is important to understand the factors that influence a stepfather to be more or less involved in the care of their stepchildren. Few studies have examined both biological fathers and stepfathers together on multiple sets of parenting variables. Thus, the current study aims to compare biological fathers and stepfathers on a model of paternal involvement.

Participants were 306 biological fathers and 69 stepfathers. In order to participate, fathers had to …

Work Groups And Teams In Organizations: Review Update, Steve W. J. Kozlowski, Bradford S. Bell

Bradford S Bell

This review chapter examines the literature on work team effectiveness. To begin, we consider their nature, define them, and identify four critical conceptual issues—context, workflow, levels, and time—that serve as review themes and discuss the multitude of forms that teams may assume. We then shift attention to the heart of the review, examining key aspects of the creation, development, operation, and management of work teams. To accomplish objectives of breadth and integration, we adopt a lifecycle perspective to organize the review. Topics involved in the team lifecycle include: (1) team composition; (2) team formation, socialization, and development; (3) …

Effects Of Caffeine In Operant Learning And Locomotor Activity, Daniel Kharlas

2015 Undergraduate Awards

Caffeine is widely considered to be a reinforcer in humans, but this effect is difficult to measure in non-human animals. This study extended the understanding of the effects of caffeine on reinforcement and locomotor activity by testing rat animal models. A group of 24 adult male Long Evans rats was split into three groups, caffeine (15mg/kg), Scopolamine (spatial learning inhibitor) or a NaCl control. Each drug was administered 15 min prior to behavioural testing. The rats were given one habituation session to familiarize with eating the reinforcing agent, one baseline session before testing and on test day were monitored for …

Motivating The Solicited And Unsolicited Sharing Of Tacit Knowledge Through The Process Of Externalization, Sheila Yvonne Sorensen

CCE Theses and Dissertations

While several U. S. firms have invested in Knowledge Management (KM) tools and software, it has become apparent that investments must be made in additional facets of KM, such as knowledge sharing (KS), thought by many researchers to be the most important component of KM. Of the two types of KS, explicit and tacit, the sharing of tacit knowledge has been shown to contribute the most to an organization’s performance. However, since tacit knowledge is difficult to both convey and acquire, this unshared tacit knowledge may ultimately harm an organization when, without the appropriate knowledge, individuals cannot effectively perform their …

Motivation, Mindfulness, And Metabolic Factors Predicting Adolescent Adherence And Attrition In A Multidisciplinary Weight Management Program, Stephen Trapp

Theses and Dissertations

Estimated rates of obesity are notably high in the United States and pose a significant public health concern. A number of deleterious physical and psychosocial conditions are associated with pediatric obesity and the cost of its treatment is considerable. Accordingly, the number of weight management treatments has increased to meet this growing public health challenge. Unfortunately, insufficient participation in weight management treatment, namely low adherence and high attrition, often impede the effectiveness of these programs. Although the barriers associated with inadequate adherence and elevated rates of attrition are documented, there is a dearth of research on the predictors of the …

Student Motivation: Teacher Perceptions, Beliefs And Practices, Teresa M. D'Elisa

PCOM Psychology Dissertations

The purpose of this study was to examine teachers' beliefs, perceptions and practices related to student motivation. Two-hundred-and-six teachers from 13 states completed an on-line survey containing the Perception of Student Motivation questionnaire (PSM), Motivating Strategies Questionnaire (MSQ), and researcher-devised questions examining theoretical beliefs and practices. Results reveal that teachers consider motivation to be an important part of their teaching. Teachers' reporting feeling efficacious for diagnosing and intervening for student motivation and believing in the malleability of motivation was found to correlate with motivational strategy use. This finding was consistent with previous research. However, their endorsement of theoretical beliefs and …

Gender, Instructional Method, And Graduate Social Science Students' Motivation And Learning Strategies, Mae Lynn Spahr

Walden Dissertations and Doctoral Studies

The purpose of the current study was to learn how gender and learning method affect motivation and learning strategies in psychology, counseling, and social work graduate students. The variables of gender, learning method, motivation, and learning strategies are used by the self-regulation model to learning and the theory of independent learning to measure a student's academic success. Increasing the knowledge of these variables will be of interest to academic institutions and to the field of educational psychology because little is known about their interaction. The study's design was factorial quasi-experimental; it used a cross sectional survey consisting of a 2 …

Perceptions Of Leadership: Impact Of Leadership Style And Gender On Employee Motivation, Kristin Marquette Walker

Walden Dissertations and Doctoral Studies

Researchers suggest that individuals in Corporate America have stereotypes about the ways in which men and women lead. They also have found that a leader's style and gender can impact employees' job satisfaction, performance, and engagement. However, researchers have provided little empirical evidence about the specific relationship of leadership style and gender on employee motivation. The purpose of this quantitative study was to examine the effects of leadership style, as measured by the Multifactor Leadership Questionnaire (MLQ), and a leader's gender on employee motivation, as measured by the Work Preference Inventory (WPI). Because it was assumed that small organizations would …

Relationally-Autonomous Reasons As A Predictor Of Collegiate Athletic Performance, Josef Max Katzman

Online Theses and Dissertations

The current proposed study examines a concept that has been looked at before but now using a new specific population. Previous research examined shows that reasons for motivation affect goal attainment and success. The current study is looking at how relational autonomous reasons for motivation play a role in goal attainment in athletes. Eastern Kentucky University athletes were administered a short questionnaire and their previous athletic performance was used as well. The two sets of data were then used to examine the relationship between the two variables. The results of the study showed a positive correlation between Relationally-Autonomous Reasons (RAR) …
