However, the majority of these studies may include, but do not exclusively, study the motivations and experiences of genital piercings in the transgender community. This study uses a qualitative design to explore the motivations, expectations, and experiences of getting a genital piercing within the transgender community, as well as how genital piercings relate to transgender identities. Methods. Participants were required to be at least 18, have a genital piercing, and identify as transgender. Recruitment was conducted through Facebook and a professional piercer. …


Self-Efficacy, Implicit Theories Of Ability, And 2 X 2 Achievement Goal Orientation: A Mediation Analysis In Collegiate Athletics, Cory Cottrell Jan 2018

Self-Efficacy, Implicit Theories Of Ability, And 2 X 2 Achievement Goal Orientation: A Mediation Analysis In Collegiate Athletics, Cory Cottrell

College of Graduate Studies: Theses & Dissertations

Achievement goal theory encompasses the adaptive and maladaptive responses to achievement situations and has a strong background in sport research. (Dweck, 1986; Nicholls, 1984; Senko, Hulleman, & Harackiewicz, 2011). A 2007 meta-analysis established self-efficacy and implicit theories of ability as antecedents of achievement goal orientation (Payne, Youngcourt, Beaubien, 2007). Using the 2 x 2 achievement goal paradigm the purpose of the study looks to evaluate antecedents of self-efficacy and implicit theories of ability on achievement goal endorsement in collegiate student athletes. The current study examined implicit theories of ability as a mediator between self-efficacy and each of the 2 x …


The Impact Of Emotion Regulation Strategies On Negative Affect And Working Memory Capacity, Jessie Kaye Weber Jan 2018

The Impact Of Emotion Regulation Strategies On Negative Affect And Working Memory Capacity, Jessie Kaye Weber

USC Aiken Psychology Theses

Emotion regulation can be conceptualized as an individual’s ability to direct attention toward or away from a particular emotion eliciting stimuli (Gross, 2002). The current study examined the effectiveness of emotion regulation strategies at reducing the impact of negative affect and the subsequent impact on working memory capacity. Previous studies found differences in the use of cognitive reappraisal, expressive suppression, and mindful attention as emotion regulation strategies in relation to positive affect but no comparison has been made in regards to negative affect. In the current study, individuals assigned to use expressive suppression reported significantly less increase in negative affect …

Leadership: A Resource In The Workplace, Wyatt Edward Stahl Jan 2018

Leadership: A Resource In The Workplace, Wyatt Edward Stahl

Wayne State University Theses

Leadership is an organizational component that has seen considerable interest in the I/O psychology literature. The current study aimed to expand on this literature by investigating the extent to which the relation between leadership style and strain outcomes varies based on employee social class. Participants were asked to complete a survey assessing leadership style of their supervisor, indicators of stress, indicators of work-related strain, and components of social class. Results suggested that individuals of lower social class experience higher levels of stress and strain. Additionally, individuals with leaders who are more transformational experience lower levels of stress and work-related strain. …


Why Less Property Is More: Inclusion, Dispossession, & Subjective Well-Being, David Fagundes Jan 2018

Why Less Property Is More: Inclusion, Dispossession, & Subjective Well-Being, David Fagundes

Faculty Articles

The twin notions of exclusion and possession dominate our cultural and legal conceptions of property. This Article uses the lens of hedonics—the emergent science of happiness—to make a case for the less appreciated notions of inclusion and dispossession. Evidence from this new field shows that owners maximize their welfare, not when they amass land and chattels and keep others away from them, but when they pursue the polar-opposite strategies of inclusion and dispossession, such as sharing their property, donating it to charity, or giving it away. This Article begins its defense of inclusion and dispossession by providing background about the …


Fluoxetine Exposure Results In Decreased Sensitivity To Cocaine And Sucrose Later In Life: A Study In Female C57bl/6 Mice, Francisco Javier Flores Ramirez Jan 2018

Fluoxetine Exposure Results In Decreased Sensitivity To Cocaine And Sucrose Later In Life: A Study In Female C57bl/6 Mice, Francisco Javier Flores Ramirez

Open Access Theses & Dissertations

Preclinical evidence indicates that exposure to psychotropic medications, during early development, results in long-lasting altered responses to stress- and reward-related stimuli. However, these animal studies have been conducted, primarily, using male subjects. This is surprising, given that clinical data suggests that females have a higher likelihood, than their male counterparts, to be diagnosed with mood-related illnesses, and thus, be prescribed with psychotropic medications, mostly antidepressants. Therefore, to examine whether enduring reward-related alterations are exhibited as a result of antidepressant exposure, in female subjects specifically, we exposed C57BL/6 female mice to fluoxetine (FLX; 250 mg/l in their drinking water). Specifically, separate …


The Relationship Between Millennials' Attitudes Towards The United States And Their Goals And Personal Constructs, Angelica M. Hernandez Jan 2018

The Relationship Between Millennials' Attitudes Towards The United States And Their Goals And Personal Constructs, Angelica M. Hernandez

Honors Undergraduate Theses

The purpose of this study was to examine various aspects of Millennials' attitudes related to their beliefs about the United States and in the context of their personal, career, and family goals and ethnic identity. Another purpose of this study was to determine if selected personality variables would predict attitudes toward the United States. It was found that Millennials who held positive attitudes toward the United States in terms of being a viable country for them also had relatively clear and developed personal, career, and family goals. Moreover, three personality variables—resiliency, optimism, and (inversely) cynicism significantly contributed to Millennials' views …

This feasibility study aimed to employ youth sport as a creative and engaging context to facilitate life skills development in underprivileged youth in eSwatini. Specifically, this study explored the youth participation experiences, positive youth outcomes, and implementation successes and challenges of a sport program for underprivileged youth …


Financial Socialization Of College Students: Domain-General And Domain-Specific Perspectives, Ji Hyun Kim, Julia C. Torquati Jan 2018

Financial Socialization Of College Students: Domain-General And Domain-Specific Perspectives, Ji Hyun Kim, Julia C. Torquati

Department of Child, Youth, and Family Studies: Faculty Publications

This study investigated the association of domain-general and domain-specific parenting practices with college students’ financial attitudes and behaviors. Data came from a survey of college students (n = 585, 156 males) aged 19–32 attending a Midwestern University. Parents’ financial behaviors significantly predicted college students’ financial attitudes. Path analysis indicated that college students’ financial attitudes mediated the association between their perceptions of parents’ financial behaviors and their own financial behaviors. Parental avoidance of financial conversation was inversely associated with college students’ financial attitudes, and parental disclosure of financial information was positively associated with college students’ financial attitudes. Family communication pattern significantly …

Participants suggested areas for improvement such as additional information for helping children cope, conflict resolution strategies, handling legal issues, and understanding how divorce impacts children based …


Media Body Images And Males' Body Dissatisfaction, Muscularity, Disordered Eating, And Depression, Diana Carrillo Jan 2018

Media Body Images And Males' Body Dissatisfaction, Muscularity, Disordered Eating, And Depression, Diana Carrillo

Walden Dissertations and Doctoral Studies

Body objectification theories propose that humans have an innate desire to compare themselves with others. When self-objectification is influenced by media exposure to idealized body images, results may be unrealistic self-perceptions and increased risk of depression, eating pathology, and overexercising. Although considerable work has been done to study these processes among women, much less is known about effects of media exposure on adult men. In response to this gap, this quantitative research study examined effects of exposure to an idealized man's body image on men observers' body dissatisfaction and related behaviors. A convenience sample of 119 freshman and sophomore community …


A Generative Model Of The Mutual Escalation Of Anxiety Between Religious Groups, F. Leron Shults, Ross Gore, Wesley J. Wildman, Christopher J. Lynch, Justin E. Lane, Monica D. Toft Jan 2018

A Generative Model Of The Mutual Escalation Of Anxiety Between Religious Groups, F. Leron Shults, Ross Gore, Wesley J. Wildman, Christopher J. Lynch, Justin E. Lane, Monica D. Toft

VMASC Publications

We propose a generative agent-based model of the emergence and escalation of xenophobic anxiety in which individuals from two different religious groups encounter various hazards within an artificial society. The architecture of the model is informed by several empirically validated theories about the role of religion in intergroup conflict. Our results identify some of the conditions and mechanisms that engender the intensification of anxiety within and between religious groups. We define mutually escalating xenophobic anxiety as the increase of the average level of anxiety of the agents in both groups overtime. Trace validation techniques show that the most common conditions …


Insulin Modulates The Strong Reinforcing Effects Of Nicotine And Changes In Insulin Biomarkers In A Rodent Model Of Diabetes, Bryan Cruz Jan 2018

Insulin Modulates The Strong Reinforcing Effects Of Nicotine And Changes In Insulin Biomarkers In A Rodent Model Of Diabetes, Bryan Cruz

Open Access Theses & Dissertations

This study examined whether the strong reinforcing effects of nicotine and changes in insulin biomarkers observed in diabetic rats are modulated via insulin. A model of diabetes was employed involving administration of streptozotocin (STZ), which produces hypoinsulinemia in rats. The present study included vehicle- or STZ-treated rats that received sham surgery or an insulin pellet. Two-weeks later, the rats were given extended access to intravenous self-administration (IVSA) of saline or nicotine. Concomitant changes in food intake, water responses, and body weight were assessed during 12 days of IVSA. After the last session, plasma levels of insulin, leptin, amylin, and glucagon-like …


A Psychometric Evaluation Of The Treatment Self-Regulation Questionnaire (Tsrq) For Assessing Motivations For Responsible Drinking, Dylan Keith Richards Jan 2018

A Psychometric Evaluation Of The Treatment Self-Regulation Questionnaire (Tsrq) For Assessing Motivations For Responsible Drinking, Dylan Keith Richards

Open Access Theses & Dissertations

Self-determination theory (SDT) may be useful for understanding alcohol use and alcohol-related consequences among college students. A version of the Treatment Self-Regulation Questionnaire (TSRQ; Ryan & Connell, 1989) exists for assessing motivations proposed by SDT for responsible drinking, but no study has evaluated its psychometric properties. Thus, the purpose of the present studies was to provide a psychometric evaluation of this version of the TSRQ. In Study 1, among a convenience sample of college student drinkers (n = 308), a four-factor structure of the TSRQ that is theoretically consistent with SDT was supported; however, the amotivation subscale demonstrated unacceptable internal …


Maternal Control, Shame, And Alexithymia, Alyson Pogue Jan 2018

Maternal Control, Shame, And Alexithymia, Alyson Pogue

EWU Masters Thesis Collection

There is research to suggest that a girl’s negative relationship with her mother can affect her psychological adjustment as an adult. One example of this negative relationship is a mother who excessively controls her daughter. This type of negative relationship is associated with many psychological difficulties, including alexithymia (i.e. the inability to identify and express what one is feeling) and shame (i.e. pervasive feelings of worthlessness and inadequacy; Kooiman et al., 2004; Kapur & Rai, 2013). A controlling mother can make her child feel like she lacks autonomy (i.e. she lacks a sense that she is capable of accomplishing important …

Children’S Emotion Regulation And Attachment To Parents: Parental Emotion Socialization As Moderator, Emine Ahmetoglu, Gökçen Ilhan Ildiz, Ibrahim H. Acar, Amy J. Encinger

Department of Child, Youth, and Family Studies: Faculty Publications

We examined the associations among parental emotion socialization, and children’s emotion regulation and attachment to parents. In particular, we examined the moderating role of parental emotion socialization in the relationship between children’s emotion regulation and attachment to parents. Participants were 78 Turkish children (49 boys) aged from 60 to 77 months and their parents. Parents reported on the socialization strategies they used for their children’s emotions and on their children’s emotion regulation, and we assessed children’s attachment to parents via the Doll Story Completion Task. Results revealed that parents’ minimization reaction to children’s emotions moderated the association between children’s emotion …

Introduction To Parenting From Afar And The Reconfiguration Of Family Across Distance, Maria Rosario De Guzman, Jill Brown, Carolyn Edwards Jan 2018

Introduction To Parenting From Afar And The Reconfiguration Of Family Across Distance, Maria Rosario De Guzman, Jill Brown, Carolyn Edwards

Department of Child, Youth, and Family Studies: Faculty Publications

Anthropologists have provided a rich research literature on family life, documenting the quite extreme variations in emotional and interactional closeness of the husband-wife relationship with respect to sleeping, eating, work, and leisure. For example, John and Beatrice Whiting (l975a) studied the dimension of what they characterized as husband-wife "aloofness versus intimacy:' They and other anthropologists have correlated this dimension of husband-wife closeness with male cross-sex identity, male involvement in warfare and group defense (extensive vs. unpredictable), marriage type (monogamous vs. polygynous), household structure (nuclear vs. extended, joint, or polygynous), preferred leisure and work partners (same-gender vs. mixed gender, paternal interaction …


How Do Differing Stakeholders Perceive Instances Of Literacy Instruction?, Rachel E. Schachter, Ann Matthews, Shayne B. Piasta Jan 2018

How Do Differing Stakeholders Perceive Instances Of Literacy Instruction?, Rachel E. Schachter, Ann Matthews, Shayne B. Piasta

Department of Child, Youth, and Family Studies: Faculty Publications

In this study, we investigated how early childhood teachers’ perspectives on their enacted literacy instruction aligned with the perspectives of observers of that same instruction. Two master teachers and two researchers, all with early childhood expertise, observed and reported their perspectives of 45 instances of literacy instruction. These were examined for alignment across each other and with teachers’ descriptions of their thinking during the instruction. Participants’ perceptions of instruction tended to align, yet there were notable differences in perceptions about context and goals. Although we often found common ground among participants regarding the purpose of instruction, there were interesting variations …


Observed Quality And Consistency Of Fifth Graders’ Teacher–Student Interactions: Associations With Feelings, Engagement, And Performance In School, Jennifer Locasale-Crouch, Faiza Jamil, Robert C. Pianta, Kathleen Moritz Rudasill, Jamie Decoster Jan 2018

Observed Quality And Consistency Of Fifth Graders’ Teacher–Student Interactions: Associations With Feelings, Engagement, And Performance In School, Jennifer Locasale-Crouch, Faiza Jamil, Robert C. Pianta, Kathleen Moritz Rudasill, Jamie Decoster

Department of Child, Youth, and Family Studies: Faculty Publications

This study examined how overall quality and within-day consistency in fifth graders’ teacher-student interactions related to feelings about, engagement, and academic performance in school. Participants were 956 children in a national study. Students who experienced higher quality interactions reported more positive feelings about school, were more engaged, performed better in math and reading, and had more closeness and less conflict with teachers. Independent of overall interaction quality, students who experienced less consistency in their interactions with teachers, whether it was with the same teacher or across teachers, were less engaged and had more teacher-reported conflict. Findings emphasize the separate contributions …


Predicting Similarity Judgments In Intertemporal Choice With Machine Learning, Jeffrey R. Stevens, Leen-Kiat Soh Jan 2018

Predicting Similarity Judgments In Intertemporal Choice With Machine Learning, Jeffrey R. Stevens, Leen-Kiat Soh

Jeffrey Stevens Publications

Similarity models of intertemporal choice are heuristics that choose based on similarity judgments of the reward amounts and time delays. Yet, we do not know how these judgments are made. Here, we use machine-learning algorithms to assess what factors predict similarity judgments and whether decision trees capture the judgment outcomes and process. We find that combining small and large values into numerical differences and ratios and arranging them in tree-like structures can predict both similarity judgments and response times. Our results suggest that we can use machine learning to not only model decision outcomes but also model how decisions are …


Heterogeneity And Parsimony In Intertemporal Choice, Michel Regenwetter, Daniel R. Cavagnaro, Anna Popova, Ying Guo, Chris Zwilling, Shiau Hong Lim, Jeffrey R. Stevens Jan 2018

Heterogeneity And Parsimony In Intertemporal Choice, Michel Regenwetter, Daniel R. Cavagnaro, Anna Popova, Ying Guo, Chris Zwilling, Shiau Hong Lim, Jeffrey R. Stevens

Jeffrey Stevens Publications

Behavioral theories of intertemporal choice involve many moving parts. Most descriptive theories model how time delays and rewards are perceived, compared, and/or combined into preferences or utilities. Most behavioral studies neglect to spell out how such constructs translate into heterogeneous observable choices. We consider several broad models of transitive intertemporal preference and combine these with several mathematically formal, yet very general, models of heterogeneity. We evaluate 20 probabilistic models of intertemporal choice using binary choice data from two large-scale experiments. Our analysis documents the interplay between heterogeneity and parsimony in accounting for empirical data: We find evidence for heterogeneity across …


Criminological Self-Efficacy: Increased Or Hindered From Crime Tv Shows, Dorothy Moore Jan 2018

Criminological Self-Efficacy: Increased Or Hindered From Crime Tv Shows, Dorothy Moore

All Master's Theses

There is an age-old question that surrounds whether or not media have an effect on its viewers. There is substantial evidence that supports the claim that violent content in media may increase relational, physical, and/or overall aggression levels. The aim of the current study is to explore the relationship between several factors that may be related to one’s belief in one’s ability (self-efficacy) to commit and get away with murder. These factors are the amount of crime TV a person watches, aggressive tendency, recklessness tendency, and potential protective factors. It is hypothesized that the more crime TV watched, the higher …
