Estimation Of Correlation Confidence Intervals Via The Bootstrap: Non-Normal Distributions, John Mart V. Delosreyes Oct 2019

Estimation Of Correlation Confidence Intervals Via The Bootstrap: Non-Normal Distributions, John Mart V. Delosreyes

Psychology Theses & Dissertations

Estimating confidence intervals (CIs) for the correlation has been a challenge. The challenge stems from the metamorphic nature of the sampling distribution of the correlation being bound by-1≤ρ≤1. The nonparametric nature of the bootstrap makes it a good option for estimating correlation CIs. However, there have been mixed results about the robustness of bootstrap CIs for the correlation with non normal data. This had led the literature to suggesting the use of transformation methods to estimate correlation CIs. However, transformation methods carry a risk of the original data being misrepresented. Thus, further investigation of bootstrap CIs for the correlation is …

The Development And Validation Of An Ideal Point Measure Of Work Engagement, Michael M. Denunzio Sep 2019

The Development And Validation Of An Ideal Point Measure Of Work Engagement, Michael M. Denunzio

Dissertations, Theses, and Capstone Projects

Work engagement has been an extremely popular area of research and practice over the past two decades. However, organizational scholars have yet to thoughtfully consider alternative and potentially more appropriate ways of modeling how individuals report their work engagement and, relatedly, measuring the construct. This dissertation seeks to establish and support the position that (1) individuals use an ideal point (vs. dominance) process to identify how engaged they are and respond to work engagement items, and (2) an ideal point framework can be used to develop a construct valid work engagement scale with good psychometric properties. Since no such scale …

Examining Relations Between Executive Functions And Decoding: A Meta-Analytic Investigation, Teresa Ober Sep 2019

Examining Relations Between Executive Functions And Decoding: A Meta-Analytic Investigation, Teresa Ober

Dissertations, Theses, and Capstone Projects

Introduction: The Simple View of Reading (SVR) is one of several established models of reading that present decoding and linguistic comprehension as critical skills in the development of reading competencies. Previous research has highlighted the connection between reading comprehension and cognitive skills, including those which fall under the term of executive functions (EF; for a review, see Follmer, 2018). EF may also be critical in the development of decoding. According to the dual route model of word recognition (Coltheart, 2006), decoding involves two separable processes; the phonological route, involving encoding and retrieval of letter-sound associations (also called phoneme-to-grapheme correspondence rules), …

How Does Alcohol Intoxication Impair Risk Detection Of Sexual Assault? Testing An Integration Of Alcohol Myopia And Social Information Processing Theories, Alexander James Melkonian Aug 2019

How Does Alcohol Intoxication Impair Risk Detection Of Sexual Assault? Testing An Integration Of Alcohol Myopia And Social Information Processing Theories, Alexander James Melkonian

Graduate Theses and Dissertations

Sexual assault among young adults is a highly prevalent public health concern. Alcohol is often implicated as a risk factor for sexual assault through its impairing effects on an individual’s ability to process and respond to social cues in the environment. The effect of alcohol myopia can result in greater focus of attention on salient environmental cues. The relationship between alcohol intoxication and resulting behavior may depend on what type of information is most salient. The current study examined the effects of alcohol on social information processing as it relates to sexual assault risk detection. Method: Participants were 48 young …

Moral Foundations Of U.S. Political News Sources, William Edward Padfield May 2019

Moral Foundations Of U.S. Political News Sources, William Edward Padfield

MSU Graduate Theses

The media ecosystem has grown, and political opinions have diverged such that there are competing conceptions of objective truth. Commentators often point to political biases in news coverage as a catalyst for this political divide. The Moral Foundations Dictionary (MFD) facilitates identification of ideological leanings in text through frequency of the occurrence of certain words. Through web scraping, the researcher extracted articles from popular news sources’ websites, calculated MFD word frequencies, and identified words’ respective valences. This process attempts to uncover news outlets’ positive or negative endorsements of certain moral dimensions concomitant with a particular ideology. In Experiment 1, the …

Test Emotions, Value, And Self-Efficacy: A Longitudinal Model Predicting Examinee Effort And Performance On A Low-Stakes Test, Paulius Satkus May 2019

Test Emotions, Value, And Self-Efficacy: A Longitudinal Model Predicting Examinee Effort And Performance On A Low-Stakes Test, Paulius Satkus

Masters Theses, 2010-2019

The validity of scores from low-stakes tests may be compromised by examinee motivation. Expectancy-Value theory (EV) has been used to frame the antecedents of examinee motivation in low-stakes testing contexts. According to EV theory, the perceived value of the test and the expectancy to succeed on the test directly affect examinee effort, which then affects test performance. Cross-sectional research studies in low-stakes testing contexts offer some support of EV theory. Control-Value theory (CV) serves as another theory to understand motivation toward a task. CV theory encompasses the constructs of expectancy and value from EV theory, but incorporates test emotions as …

Are All Cognitive Items Equally Prone To Position Effects? Exploring The Relationships Among Item Features And Position Effects, Thai Quang Ong May 2019

Are All Cognitive Items Equally Prone To Position Effects? Exploring The Relationships Among Item Features And Position Effects, Thai Quang Ong

Dissertations, 2014-2019

One type of context effect is a position effect, which implies parameters of an item are influenced by the position of the item on the test. Researchers often discuss two types of position effects: negative position effects and positive position effects (e.g., Albano, 2013; Debeer & Janssen, 2013). Items exhibiting negative position effects become harder when placed later on the test, whereas items exhibiting positive position effects become easier when placed later on the test. Researchers have primarily examined the underlying causes of position effects through an item or person perspective (e.g., Bulut, 2015; Kingston & Dorans, 1984; Qian, 2014). …

Mathematics Attitudes And Mathematics Performance: Novel Approaches Towards Noncognitive Educational Measurement, Applications To Large-Scale Assessment Data, And Examinations Of Multigroup Invariance, Kalina Gjicali May 2019

Mathematics Attitudes And Mathematics Performance: Novel Approaches Towards Noncognitive Educational Measurement, Applications To Large-Scale Assessment Data, And Examinations Of Multigroup Invariance, Kalina Gjicali

Dissertations, Theses, and Capstone Projects

Academic performance is predicted by a multitude of demographic, contextual, cognitive, and noncognitive constructs. The noncognitive factors of achievement in mathematics that have previously been explored in depth are study skills, collaborative problem-solving, confidence, self-efficacy, and personality traits (Kyllonen, 2012). Limited applied research has explored the predictive value of noncognitive factors such as attitudes and beliefs in mathematics achievement – even though attitudes towards mathematics are a promising avenue for understanding the variability in mathematics achievement. The current research uses the theory of planned behavior (TPB) to explain high school students’ performance in mathematics in a series of three studies. …

Effects Of Talker Variability On Categorization Of Spectrally Degraded Vowels., Emily A. Dickey May 2019

Effects Of Talker Variability On Categorization Of Spectrally Degraded Vowels., Emily A. Dickey

College of Arts & Sciences Senior Honors Theses

When a person listens to a context sentence with prominent higher frequencies, the subsequent vowel sound is more likely to be perceived as being of a lower frequency and vice versa. This is a spectral contrast effect (SCE). Recent work has shown that talker variability diminishes these SCEs. They were found to be smaller when 200 sentences were spoken by a different talker each time compared to one talker (Assgari & Stilp, 2015). Cochlear Implant (CI) users’ speech categorization is also influenced by SCEs but are known to struggle with talker discrimination. Here, I tested whether talker variability affected SCEs …

Supervisor-Subordinate Conflict Negotiation: Examining The Core Concerns In Light Of Communication Accommodation And Gender Roles, Piyawan Charoensap-Kelly May 2019

Supervisor-Subordinate Conflict Negotiation: Examining The Core Concerns In Light Of Communication Accommodation And Gender Roles, Piyawan Charoensap-Kelly

Dissertations

This quasi-experimental study examined a supervisor-subordinate negotiation of an emotion-laden conflict from the lens of the core concerns framework, communication accommodation theory, and gender roles research. Results empirically support CCF that, by accommodating or attending to the employees’ core concerns, managers can stimulate employees’ positive emotion and integrative intention. However, under- and overaccommodating the core concerns can lead to distributive intention. Additionally, the employees’ perception of manager goodwill can strengthen or attenuate the positive effect of core concerns accommodativeness on outcome variables especially for male managers. Thus, moderate accommodation is recommended for male managers. For female managers, the results show …

The Effects Of Sex Role Stereotype Endorsement And Work-Family Conflict On Emerging Adult Aspirations, Andrea Fink-Armold May 2019

The Effects Of Sex Role Stereotype Endorsement And Work-Family Conflict On Emerging Adult Aspirations, Andrea Fink-Armold

UNLV Theses, Dissertations, Professional Papers, and Capstones

Workplace and household inequality remain prevalent in the United States and sex role (e.g. breadwinner and caregiver) stereotypes affect the roles that individuals seek out. This research used a mixed-methods approach to investigate the effects of sex role stereotypes and expected work-family conflict on the work and family aspirations of emerging adults. A racially diverse sample wrote freely about their future selves for ten minutes then completed measures to evaluate their sex-role stereotype endorsement, expected work-family conflict, and personal preferences for career and family roles. Results indicate that endorsement of stereotypes predicts increased expectations of work-family conflict, for both men …

An Investigation Into The Structure Of Self-Control, Parker A. Dreves May 2019

An Investigation Into The Structure Of Self-Control, Parker A. Dreves

Electronic Theses and Dissertations

Self-control has been measured using a variety of methods including self-report measures, cognitive inhibition tasks, delay discounting and delay of gratification tasks, and persistence and willpower tasks. Although these are all theoretically linked to processes involved in self-control, recent evidence has shown that these diverse measurement techniques relate only minimally to one another. Assuming that self-control is a reflective construct, this would indicate that many of these tasks are poor indicators of self-control. The present research challenges the common assumption that self-control is a reflective construct and instead proposes that self-control is a formative construct. Conceptualizing self-control as a formative …

Selection Or Socialization? A Propensity Score Matched Study Of Personality And Life Events, Emorie Beck May 2019

Selection Or Socialization? A Propensity Score Matched Study Of Personality And Life Events, Emorie Beck

Arts & Sciences Electronic Theses and Dissertations

Across the lifespan, personality changes in normative ways, but the source of such change remains ambiguous. Life events may be one impetus of such change, but strong selection effects into such events makes it unclear whether such change is driven by already existing differences (selection) between people or socialization following life events. In a preregistered study, we test socialization and selection effects of the Big 5 and life events using a large (N = 19,627) representative sample of Germans and 12 life events (e.g. marriage, retirement) from the GSOEP. Using propensity score matching and Bayesian multilevel growth curve models, we …

Contextually Modulated Avoidance Behavior In Rats Post-Pavlovian Extinction, Lauren Branigan Feb 2019

Contextually Modulated Avoidance Behavior In Rats Post-Pavlovian Extinction, Lauren Branigan

Theses and Dissertations

The following study sought to examine the psychological substrates of renewal (e.g.., context dependent extinction processes) for conditioned avoidance behaviors in rats. Using signaled active avoidance conditioning, rats acquired two-way shuttle responding, to two different auditory stimuli. These behaviors were then extinguished through exposure to the auditory stimuli where shuttling behavior was now without consequence. Subjects were then tested for renewal of avoidance in three distinct renewal sequences (e.g., ABA vs ABB, AAB vs AAA, and ABC vs ABB) in three separate groups of rats. It was found that subjects showed more responding to a stimulus presented outside of its …

Psychological Characteristics Of Sex Offenders, Patrick Mcmunn Jan 2019

Psychological Characteristics Of Sex Offenders, Patrick Mcmunn

Walden Dissertations and Doctoral Studies

Current therapeutic treatment methods are ineffective in identifying at-risk sex offenders and reducing recidivism of known offenders, likely due to inadequate identification of specific traits of sex offenders. Previous research and prominent theories in the area of sex offender treatment, in terms of the biological foundation of substance abuse, behaviors of sex offenders, and the presence of aggression, helped to guide this research. Data about sex offenders were collected, as reported by mental health professionals who treat them and focused on three characteristics: maladaptive interpersonal behaviors, impulsivity, and antisocial behaviors, on which the research questions were formed to detect commonality. …

Recognizing And Anticipating Stress Related Complacent Behavior In Manufacturing Industries, Ricardo Alberto Pineda Jan 2019

Recognizing And Anticipating Stress Related Complacent Behavior In Manufacturing Industries, Ricardo Alberto Pineda

Walden Dissertations and Doctoral Studies

Numerous safety studies suggest that stress complacency related accidents in manufacturing industries continue to cause injuries or fatalities because of the absence of emotional resources for leaders, who are unable to prevent accidents when these conditions exist. Leaders of the manufactory industries may not have the appropriate emotional measures which are significant to recognize employees' underlying complacent behavior. The purpose of this quantitative correlational study was to evaluate the relationship between leaders' emotional intelligence resources and their ability to manage to prevent injuries and fatalities in the workplace. The research questions address key traits of emotional intelligence regarding emotional perceptions …
