The Influence Of Neural Reward Processing On Memory In Depression, Nathan M. Hager

Psychology Theses & Dissertations

Theories and research suggest that depression involves impaired reward sensitivity and a deficit in memory for rewarding stimuli. Some researchers propose that this memory deficit may result from reduced neural reward sensitivity, which impairs the encoding of reward-related memories, but few studies have directly probed this connection. Such research may benefit from examining the reward positivity (RewP), an event-related potential (ERP) previously linked to reduced reward sensitivity in depression. Undergraduates with high or low self-reported depression completed a task in which they chose one of three doors, revealing a neutral word written in a color which indicated an outcome of …

Examining The Effect Of Interruptions At Different Breakpoints And Frequencies Within A Task, Sarah Anastazia Powers

Psychology Theses & Dissertations

Research on the effects of interruptions shows that they can be either costly or beneficial depending on which aspects of an interruption are manipulated. One important aspect that contributes to these conflicting results concerns when an interruption occurs. The present study explored how event segmentation theory (EST) can be used to determine optimal moments for an interruption relying on hierarchical task analysis (HTA) to identify coarse and fine event boundaries. Utilizing a 2 X 3 mixed design, undergraduate students completed a trip planning task divided into three task trials. The within-subjects factor was interruption timing, which had three levels: none, …

The Effect Of Differing Degrees Of Automation And Reliability On Simulated Luggage Screening Performance, Molly M. Liechty

Psychology Theses & Dissertations

The present work examined the effects of two types of decision support systems in a simulated luggage screening task: An input aid and an output aid. An input aid supports an operator’s information gathering. An output aid supports decision making and action selection. A Time-Accuracy Function (TAF) analysis was applied to isolate processing time from performance asymptote, which conventional performance measures such as sensitivity and response time do not distinguish one from the other. Sixty participants performed a luggage screening task unaided (manual condition), with the assistance of an input aid (spatial aid), and with the assistance of an output …

The Effect Of Task Interruptions And Reliable Cues On Detection Changes Within Dynamic Scenes, Kimberly N. Perry

Psychology Theses & Dissertations

Interruptions are a common problem for attention and pose a threat to visual task performance. The Memory for Goals (MFG) theory suggests that strongly and accurately encoded cues can assist the ability to resume a primary task after an interruption (Altmann & Trafton, 2002). Encoded cues can undergo an activation decay during an interruption and become forgotten. Currently, there has been limited research on how visual interruptions affect cued recall within a dynamic environment. Thus, the goal of the present study was to examine the effect of cuing and task interruptions on change detection within dynamic scenes. Undergraduate students watched …

Associations Between Drinking, Condom Use Resistance, And Condom Use Among College Students, Caitlin B. Turner

Psychology Theses & Dissertations

Alcohol use and sexual intercourse are common behaviors among young adults in college. Drinking is considered a risk factor for unprotected sexual intercourse. Having condomless sex is associated with increased risk of contracting an STI or becoming pregnant unintentionally. Although correct and consistent condom use protects against such consequences, many individuals may resist condom use during sexual intercourse. As such, condom use resistance beliefs may be the factor through which alcohol reduces condom use. Evidence from Theory of Planned Behavior (TPB), Alcohol Expectancy Theory, and a body of evidence supports individual beliefs to be predictive of condom use intentions and …

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 Effects Of Vehicle Automation Level And Warning Type On Responses To Vehicle Hacking, Wyatt D. Mcmanus

Psychology Theses & Dissertations

Modern surface transportation vehicles often include different levels of automation. Higher automation levels have the potential to impact surface transportation in unforeseen ways. For example, connected vehicles with higher levels of automation are at a higher risk for hacking attempts, because automated driving assistance systems often rely on on board sensors and internet connectivity. As the automation level of vehicle control rises, it is necessary to examine the effect of different levels of automation have on the driver-vehicle interactions. In addition, auditory warnings have been shown to effectively attract a driver’s attention while performing a driving task, which is often …

The Effects Of Automation Transparency And Reliability On Task Shedding And Operator Trust, William Everett Lehman

Psychology Theses & Dissertations

Because automation use is common in many domains, understanding how to design it to optimize human-automation system performance is vital. Well-calibrated trust ensures good performance when using imperfect automation. Two factors that may jointly affect trust calibration are automation transparency and perceived reliability. Transparency information that explains automated processes and analyses to the operator may help the operator choose appropriate times to shed task control to automation. Because operator trust is positively correlated with automation use, behaviors such as task shedding to automation can indicate the presence of trust. This study used a 2 (reliability; between) × 3 (transparency; within) …

Improving The Sensitivity Of The Vrin-R Scale On The Mmpi-A-Rf, Stefan E. Latulip

Psychology Theses & Dissertations

When respondents to self-report measures fail to answer in accordance with item content it distorts the accuracy of obtained test scores, degrading the ability of clinicians to use results to make accurate diagnoses and recommendations. The Variable Response Inconsistency (VRIN) scale was created for the MMPI-2 and was later revised as the VRIN-r scale for the MMPI-2-RF and MMPI-A-RF in order to detect and invalidate protocols over saturated with random responding. Analyses conducted by Pitta (2016) revealed that the VRIN-r scale for the MMPI-A-RF was not ideally sensitive to the detection of random responding in protocols. This study explored adding …

Conceptualization Of Faculty Work Motivation: Overcoming The Impasse, Julie Nikolaeva Thompson

Psychology Theses & Dissertations

The work motivation literature is at an impasse. At the same time, changing economic and social conditions necessitate an ongoing transformation for how organizations motivate their workforce. Although changes in the nature of work have captured the attention of researchers, calls for more research to further develop work motivation theory have largely gone unnoticed. The scarcity of new theoretical research contributes to a lack of contextual understanding in work motivation. As such, organizational leaders continue to develop interventions based on the findings of potentially outdated work motivation theories. This may lead to diminished work motivation, productivity, and commitment, particularly for …

Effects Of Focal On Driver Calibration Of Attention Maintenance Performance Using Normalized Difference And Brier Scores, James Richard Unverricht

Psychology Theses & Dissertations

Young drivers are specifically poor at maintaining attention to the forward roadway while driving. Additionally, drivers are poorly calibrated to their own abilities, often overestimating their driving skills. The current research examines the effect of FOCAL on a young driver’s calibration using two different measures, normalized difference scores and the Brier score. Thirty-six participants received either FOCAL or Placebo training program, immediately followed by driving simulator evaluation of their attention maintenance performance. In the evaluation drive, participants had driven through four scenarios in a driving simulator with their eyes tracked. Participants were asked to perform a mock visual search task …

The Bidirectionality Of Impulsivity And Alcohol Use: An Ecological Momentary Examination Among Emerging Adults, Amy L. Stamates

Psychology Theses & Dissertations

Impulsivity is a robust risk factor for alcohol use among emerging adults (i.e., 18 to 25), but significant gaps remain in our understanding of the way that impulsivity relates to alcohol harms. Most prior research has been limited to between-level differences; thus, within-person variability in impulsivity at the momentary level and its bidirectional association with alcohol use has not been examined. Consequently, the present research used a 14-day ecological momentary assessment (EMA) design to: (1) determine momentary impulsivity as a predictor of subsequent alcohol use and problems; (2) examine the influence of alcohol use on subsequent impulsivity; (3) test socio-cognitive …

The Impact Of Diet And Psychosocial Factors Post Bariatric Surgery, Eva Rani Panigrahi

Psychology Theses & Dissertations

Bariatric surgery is a medical procedure that has been found to be an effective option for weight loss. Despite the benefits of bariatric surgery, little is known about the psychosocial factors that may impact weight outcome. The present study attempted to examine patients’ level of perceived stress, depressed mood, and diet, and the association of these factors with percent weight loss in the first 6-months after surgery. Eighty patients completed pre- and 6-months post-operative depressed mood assessment (Patient Quality Health Questionnaire – 7 [PHQ-7]), a perceived stress measure (Cohen’s Perceived Stress Scale – 10 [PSS-10]), and dietary measures (Block Dietary …

Examining Trait Mindfulness As A Moderator Of The Mediating Relationship Between Social Anxiety, Coping Motives, And Substance-Related Consequences, Cody A. Raeder

Psychology Theses & Dissertations

The present research examined the mediating relationship between social anxiety, drinking to cope with social anxiety, and alcohol-related consequences. Additionally, this study examined the mediating relationship between social anxiety, using cannabis to cope with social anxiety and cannabis-related consequences. Furthermore, this study examined whether or not trait mindfulness exhibited a moderating effect on both of these mediation relationships which have been previously observed in the literature. The study consisted of students recruited through the psychology research participant pool at a mid-sized southeastern university. Two data sets were created based on type of substance use (alcohol or cannabis). The majority of …

Who Receives More Family Related Support In The Workplace? A Meta-Analysis Of Gender Differences In Family Related Support, Daroon M. Jalil

Psychology Theses & Dissertations

The purpose of the current study was to meta-analytically estimate if gender differences exist in the provision of family related support in the workplace. Gender differences are of particular interest in the realm of family related support in the workplace because they lie at the intersection of prescribed gender roles for both men and women at home and work. Family related support plays an integral role in an employees’ willingness to utilize family friendly policies that organizations provide to meet the increasing needs of employees to balance work and family demands. Though it may seem like a simple research question, …

Examining Validity Of Aha! Ratings As A Construct Of Insight, Ekaterina Y. Shurkova

Psychology Theses & Dissertations

Currently, there are two main views on insightful problem solving. Results of the studies supporting “business-as-usual” theory suggest that the processes involved in solving insight problems are the same as in analytical problem solving—slow, controlled, and effortful, while findings of the studies supporting the restructuring theory of insight suggest involvement of fast and automatic, one-trial-learning type of processes. The goal of the current study was to investigate the construct validity of the Aha! ratings, used in many studies as the measure of insight, by isolating its three components, effort, confidence, and suddenness, and examining their correlation with working memory span. …

Anticipated Vs Experienced Work-Family Conflict: Newcomer Expectations And Early Socialization Outcomes, Seterra D. Burleson

Psychology Theses & Dissertations

Applying met expectations and newcomer socialization theory, congruence and discrepancy between anticipated work-family conflict (AWFC) and experienced WFC were examined in relation to job satisfaction, affective commitment, and turnover intent. It was hypothesized that when AWFC and WFC are in agreement outcomes are more favorable. Further, it was hypothesized that when the discrepancy is such that WFC is higher than AWFC outcomes are more favorable than vice versa. Data were collected from 205 adults, first as graduating seniors in college and again three months after starting their post-graduation jobs. Polynomial regression revealed that congruence between work interference with family (WIF) …

Effects Of Control Device And Task Complexity On Performance And Task Shedding During A Robotic Arm Task, Shelby K. Long

Psychology Theses & Dissertations

The use of robotic arms across domains is increasing, but the relationship between control features and performance is not fully understood. The goal of this research was to investigate the difference in task performance when using two different control devices at high and low task complexities when participants can shed tasks to automation. In this experiment, 40 undergraduates (24 females) used two control devices, a Leap Motion controller and an Xbox controller, to teleoperate a robotic arm in a high or low complexity peg placement task. Simultaneously, participants were tasked with scanning images for tanks. During the experiment, participants had …

Comparing The Effects Of Mental Workload Between Visual And Auditory Secondary Tasks During Laparoscopy, James P. Corcoran

Psychology Theses & Dissertations

The purpose of this study was to test Wickens’ Multiple Resource Theory (MRT) by comparing performance and subjective workload on a visual-spatial secondary task with an auditory-spatial analog when paired with visual-spatial laparoscopic primary tasks. Two primary tasks were performed with a laparoscopic box trainer: a high workload task that consisted of transferring rings from one peg to another and a low workload task that consisted of grasping and placing large pencil erasers in a bowl. It was predicted that the visual-spatial secondary task would be more sensitive when paired with the laparoscopic primary task than the auditory analog. Findings …

Identifying The Strengths And Weaknesses Of Over-The-Shoulder Attack Resistant Prototypical Graphical Authentication Schemes, Ashley Allison Cain

Psychology Theses & Dissertations

Authentication verifies users’ identities to protect against costly attacks. Graphical authentication schemes utilize pictures as passcodes rather than strings of characters. Pictures have been found to be more memorable than the strings of characters used in alphanumeric passwords. However, graphical passcodes have been criticized for being susceptible to Over-the-Shoulder Attacks (OSA). To overcome this concern, many graphical schemes have been designed to be resistant to OSA. Security to this type of attack is accomplished by grouping targets among distractors, translating the selection of targets elsewhere, disguising targets, and using gaze-based input.

Prototypical examples of graphical schemes that use these strategies …

Harsh Parenting In Military Versus Civilian Families: Does Military Culture Moderate The Influence Of Socioeconomic Status And Race?, Tiren Antinette Parker

Psychology Theses & Dissertations

Harsh parenting techniques such as yelling and spanking are commonly used in the United States to discipline children, despite the evidence that harsh parenting has a negative sequalae for children that can persistent into adulthood. Socioeconomic status (SES) and race/ethnicity have been identified as two key determinants of harsh parenting. The stressors associated with military service and parenting within military culture place families at increased risk for harsh parenting and child maltreatment. Having a better understanding of how sociodemographic factors influence parenting behaviors within the military culture may help to develop psychoeducational and parenting programs as well as therapeutic interventions …

Whose Drive Is It Anyway? Using Multiple Sequential Drives To Establish Patterns Of Learned Trust, Error Cost, And Non-Active Trust Repair While Considering Daytime And Nighttime Differences As A Proxy For Difficulty, Scott Mishler

Psychology Theses & Dissertations

Semi-autonomous driving is a complex task domain with a broad range of problems to consider. The human operator’s role in semi-autonomous driving is crucial because safety and performance depends on how the operator interacts with the system. Drive difficulty has not been extensively studied in automated driving systems and thus is not well understood. Additionally, few studies have studied trust development, decline, or repair over multiple drives for automated driving systems. The goal of this study was to test the effect of perceived driving difficulty on human trust in the automation and how trust is dynamically learned, reduced due to …
