The Effects Of Task Criticality And Target Modality On A Simulated Battlefield Search Task, Julie A. Hanson

Psychology Theses & Dissertations

Warfighters must rely on lengthy instruction manuals when asked to perform tasks in critical environments. These instruction manuals are predominantly written in text and rarely include images. Several theoretical frameworks, including the Pictorial Superiority Effect, posit images to be more effective forms of instruction for short-term memory recall tasks. It is unclear whether pictures are superior forms of instruction for use in tasks with potential life-threatening consequences. Recently, studies have attempted to define and manipulate task criticality to determine the effects a critical scenario may have on operator performance. Findings have been equivocal, perhaps because of the ambiguity associated with …

Comparing Implicit And Explicit Measures Of Sex Guilt In Predicting Sexual Behavior, Delaram Asadzadeh Totonchi

Psychology Theses & Dissertations

Sex guilt is a generalized expectancy for self-mediated punishment for violating or anticipating violating standards of proper sexual conduct. Our current knowledge about sex guilt is primarily achieved through using explicit measures, particularly the widely used Mosher Sex Guilt Inventory. Research has shown that explicit sex guilt can predict many sexual behaviors such as sexual activity, number of sexual partners, and condom use. Responses on explicit measures, however, are influenced by dissimulation and social desirability, especially when assessing socially sensitive domains such as sexual attitudes. The present study hypothesized that adding implicit sex guilt as a second predictor to the …

Examining The Factors Related To Bisexual Individuals' Preference For Future Parenting Partner, Laurin Beth Roberts

Psychology Theses & Dissertations

Although a notable amount of research has examined sexual minority parents and their families over the last decade, very little literature has focused on bisexual parents. Most of the research emphasis has been placed on parenting by lesbian women and gay men, with parenting by bisexual individuals often being subsumed by these categories. There is currently a lack of understanding of what factors contribute to bisexual individuals’ preference for gender of their future parenting partner. Because of this, the current study examined the factors related to parenting partner preferences of bisexual students. Forty-seven bisexual individuals completed a series of questionnaires …

Risk Factors For Military Sexual Trauma: Pre-Military Trauma, Psychological Adjustment, Combat Exposure, And Alcohol Use At The Time Of The Trauma, Brittany Hollis

Psychology Theses & Dissertations

Military sexual trauma (MST) is a serious and understudied problem in the military. It may be a particularly important problem for women who have experienced pre-military trauma (i.e., childhood physical or sexual abuse). This study examined the role that premilitary trauma plays in the development of poor psychological adjustment (i.e., depression, anxiety and somatic symptoms) and whether psychological adjustment mediates the relationship between pre-military trauma and MST in a sample of 169 military women recruited from the community. Combat exposure and alcohol use at the time of the trauma by the victim, were examined as potential moderators of the relationship …

Employee Behavioral Intention And Technology Use: Mediating Processes And Individual Difference Moderators, Robert Conrad Brusso

Psychology Theses & Dissertations

Considering the substantial amount of time and organizational resources that are involved in the development and implementation of end-user technology (e.g., communication software platforms, social networking sites) within organizations, it is imperative to understand the factors that best predict use of end-user software. Although technology acceptance models, grounded in broader theories of behavior, do exist, these models fall-short in determining the most proximal antecedents of actual behavior. Currently, the majority of the research in the information technology arena posits behavioral intention as the most proximal antecedent of technology use. Behavioral intention does explain variance in use, but this relationship has …

An Evaluation Of Game Fiction-Enhanced Training: Using Narrative To Improve Trainee Reactions And Learning, Michael Beaumont Armstrong

Psychology Theses & Dissertations

Gamification is growing in popularity in instructional contexts like education and workplace training, but it is unclear which game elements are specifically conducive to improve learning outcomes. Narratives, which represent one way the game element “game fiction” is commonly implemented, have been used to improve learning outcomes over expository texts in the context of psycholinguistics, whereas the Technology-Enhanced Training Effectiveness Model (TETEM) proposes that certain individual differences impact the relationships between technology-enhanced training and learning outcomes. From this theoretical basis, this study gamified a training session with game fiction in order to improve reactions to training and learning over the …

Support For Gestalt Versus Business-As-Usual Theories Of Insight Depends On Operational Definition Of Insight, Kimberly D. Lee

Psychology Theses & Dissertations

Some theories propose that insight involves automatic processes that are responsible for restructuring. Other theories postulate that the mechanisms surrounding restructuring are controlled and effortful. The current study tested these theories by comparing different methodology and operational definitions that have been used in previous research to investigate the nature of “Aha!” experiences and impasse in insightful problem solving. One hundred two undergraduate psychology students from Old Dominion University completed working memory tasks, six classic insight problems, and gave initial problem representation ratings for the insight problems before solution attempt. Using a think-aloud protocol, we assessed the occurrence of impasse during …

Donepezil’S Effect On Cardiac Function In Patients With Alzheimer’S Disease Through An In Vivo, Non Invasive Measure Of Cardiac Autonomic Function, Lewis P. Hackett

Psychology Theses & Dissertations

The aim of the current study was to explore the effects of the medication Donepezil (Aricept®) on cardiac autonomic function for individuals diagnosed with mild to moderate (probable) Alzheimer’s disease (AD). Using age (± 3 years) and gender matched controls, differences in heart rate variability (HRV) among individuals with Alzheimer’s disease were compared to healthy controls over a period of six months (session 1 [baseline], session 2 [3 months], and session 3 [6 months]) in both supine and standing positions. HRV was obtained through frequency-domain (Low Frequency Power, High Frequency Power, RMSSD, LF/HF Ratio) and time-domain (six minutes) measures using …

Ptsd Symptom Severity And Neurocognitive Performance As A Function Of Combined Tms And Imaginal Exposure In Oif/Oef Combat Veterans With Treatment Resistant Ptsd, Katharine Seagly

Psychology Theses & Dissertations

Posttraumatic Stress Disorder (PTSD) is a commonly occurring mental health diagnosis, and is particularly prevalent in combat veterans. Although there has been some success treating PTSD with various forms of therapy, many cases remain refractory to the current standard of care. This pilot study combines transcranial magnetic stimulation (TMS) to the right dorsolateral prefrontal cortex (DLPFC) and the supplementary motor area (SMA) with a standardized exposure protocol for the treatment of chronic, treatment-resistant PTSD. The aims are to (1) determine if the treatment is safe and well tolerated, (2) determine if PTSD and concomitant depression and anxiety symptoms improve, and …

The Differential Effect Of Anticipated Work-Family Conflict On The Stem Major Embeddedness Of Men And Women, Dante P. Myers

Psychology Theses & Dissertations

It is nationally concerning that many students who begin as Science, Technology, Engineering and Mathematics (STEM) majors do not complete their degrees. Of additional concern is that among the STEM students who do persist to degree completion, women are severely underrepresented. The present research investigates the extent to which anticipated conflicts between work and family life (AWFC) are negatively related to students’ embeddedness in their STEM majors, especially the STEM embeddedness of women. The hypothesized model was tested using structural equation modeling in Mplus-7 with a sample of 218 STEM students from an archival database. As hypothesized, work-family decision making …

A Daily Diary Investigation Of Discrimination And Binge Eating Among Lesbian Women, Tyler Mason

Psychology Theses & Dissertations

Lesbian women may experience discrimination because of their gender and their sexual orientation termed sexism and heterosexism, respectively. Both sexism and heterosexism are associated with increased psychological distress and negative affect among lesbian women. Furthermore, preliminary evidence suggests that heterosexism is associated with binge eating among lesbian women. However, the relationship between discrimination and binge eating has received limited empirical examination. This study examined associations between sexism and heterosexism, negative affect, and binge eating using a daily diary methodology. Participants were recruited online through social media and LGBT organizations after completing an online eligibility survey with measures of demographics, binge …

Effects Of Varying Degrees Of Fixed And Random Responding On The Validity Of Score Interpretation For The Sp And Psy-5 Scales Of The Mmpi-2-Rf, Joseph Brooks Minifie

Psychology Theses & Dissertations

The Minnesota Multiphasic Personality Inventory – 2 Restructured Form (MMPI-2- RF; Tellegen & Ben-Porath, 2008/2011) is a widely used self-report measure of psychopathology and personality. However, the self-report format of the MMPI-2-RF suggests that interpretation of its scales and the clinical recommendations that follow are vulnerable to invalid response styles. This dissertation builds upon previous research (Handel, Ben-Porath, Tellegen, & Archer, 2010) to examine the effect of random and fixed responding, as measured by the VRIN-r and TRIN-r Scales, on the 28 SP and PSY-5 Scales. A computer simulation procedure was used to insert increasing degrees of inconsistent responding into …

The Association Of Racial Identity And Locus Of Control With Eating Attitudes And Obesity In African American College Women, Jamie Grisham

Psychology Theses & Dissertations

African-American women have been disproportionately affected by the obesity epidemic in the United States, and studies have suggested that sociocultural factors may have a negative influence on weight and weight loss efforts. Relatedly, other studies have found that African-American women have reported feeling less motivated to lose weight than other ethnic groups. Previous research has also indicated that locus of control plays a role in some health outcomes for African America women. The current study aimed to examine the impact of Black identity, external locus of control, and exercise motivation on obesity in African-American college women. Uncontrolled eating and exercise …

Examining The Measurement Invariance Of The Minnesota Multiphasic Personality Inventory-2-Restructured Form Internalizing Specific Problem Scales In African- American And Caucasian Men, Megan Anne Brokenbourgh

Psychology Theses & Dissertations

Test bias has long been an area of investigation in the personality assessment literature, including the MMPI-2-RF. Research on previous versions of the MMPI and MMPI-2-RF has pointed to mixed results. The current study aims to examine test bias on the MMPI-2-RF’s nine Internalizing Specific Problem Scales by examining measurement invariance using MIMIC modeling and investigating differential item functioning (DIF). After removal of invalid protocols, the first sample consisted of 2,980 protocols from various settings requested from Pearson (255 African American and 2,755 Caucasian protocols). The second sample consisted of 1,379 valid protocols from psychiatric inpatient settings (1,245 Caucasian and …

Relationship Decision-Making As A Mediator Between Regret, Autonomy, And Two Forms Of Relationship Commitment: Dedication And Constraint, Ashley Fehr

Psychology Theses & Dissertations

This study examined the relationships among autonomy, anticipated regret, decision-making, and dedication and constraint commitment of college students in romantic relationships. Two models were specified, with the first assessing autonomy as a predictor of dedication and deciding as a mediator. The second model assessed anticipated regret as a predictor of constraint and deciding again as a mediator. Participants were 267 undergraduates from a Mid-Atlantic region university, were recruited through a participant pool, and completed the study voluntarily or for course credit. To be included in analysis, participants had to be in a current dating, cohabiting, or married relationship for 30 …

Moderating Effects Of Coping Self-Efficacy And Coping Diversity In The Stress Health Relationship In African American College Students, Carol Frances Bonner

Psychology Theses & Dissertations

The present study examined the roles of coping self-efficacy and coping diversity in moderating the harmful effects of stress in a sample of African American undergraduate college students. An additional purpose of the study was to explore alternative methods of measuring coping diversity. Data were obtained from 162 participants who attended a southeastern Historically Black College/University. Hierarchical multiple regression analyses were performed to detect main effects and interaction effects of perceived stress and the two moderator variables, coping self-efficacy and coping diversity, on physical and mental health. Correlational analyses were used to assess the reliability of an alternative measure of …

Assessing The Effectiveness Of An Interval Estimation And A Visual-Spatial Secondary Task As Measures Of Mental Workload During Laparoscopy, Levi Parker Warvel

Psychology Theses & Dissertations

The goal of the present study was to compare two secondary workload tasks, specifically a time interval estimation and visual-spatial task, to determine which of these is most appropriate for the assessment of laparoscopic mental workload. Participants performed a peg transfer task in two conditions: a normal camera angle and a 90° camera angle intended to increase mental workload. Based on multiple resource theory, it was predicted the visual-spatial task would be more sensitive to the workload manipulation than the time estimation task because it draws upon the specific, as opposed to more general, attentional resources required by laparoscopy. Primary …

The Effects Of Mental Models And Expertise On Running Memory And Clinical Handoff Effectiveness, Brittany Lee Anderson-Montoya

Psychology Theses & Dissertations

The goal of the present study was to examine the effects of mental models and expertise on the ability to process handoffs of information. In addition, the role of active or passive processing was examined. Three groups of participants participated, differing in their level of clinical expertise to represent a novice, intermediate, and expert population. Participants performed an abstract running memory span task and two tasks resembling real world activities, an air traffic control (ATC) handoff task, and a clinical handoff task. For all tasks list length and the amount of information to be recalled was manipulated. Further, in the …

Categorizing Fetal Heart Rate Variability With And Without Visual Aids, Amanda Jane Ashdown

Psychology Theses & Dissertations

This present study examined the ability of clinicians and novices to correctly categorize fetal heart rate (FHR) variability with and without the use of exemplars. Clinicians and undergraduate students were asked to inspect FHR images and determine into which of four categories they belonged. Each participant took part in three conditions: one in which they were provided exemplars of prototypical FHR variability to use during their categorization task, another in which they were provided exemplars of nonprototypical FHR variability to use in their task, and a control condition in which no exemplars were available. The results showed that experts were …

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 …
