Reliability Of Longitudinal Sleep Monitoring In Amyloid-Negative And Amyloid-Positive Older Adults., Taylor Pedersen

Arts & Sciences Graduate Student Theses and Dissertations

Sleep disturbances are associated with Alzheimer’s disease (AD) pathology and cognitive symptoms, but longitudinal studies exploring sleep, AD biomarkers, and cognition are limited. Understanding changes in sleep among older adults with and without AD pathology is crucial for appropriately designing longitudinal studies of aging and AD. To assess this, sleep was longitudinally assessed (over ~3.5 years) in amyloid-negative and amyloid-positive older adults using self-reported logs, questionnaires, and at-home monitoring with a single-channel electroencephalography (EEG) device. Amyloid imaging and cognitive assessments were also performed. Test-retest reliability was evaluated using intraclass correlation coefficients, and power analysis determined sample sizes for longitudinal observational …

Do All Components Of Psychological Wellbeing Predict Cognitive Function?, Karysa Britton

Arts & Sciences Graduate Student Theses and Dissertations

Sense of purpose has been consistently associated with cognitive function. However, less is known about the associations between the other five components of wellbeing and cognitive outcomes. The current research aimed to establish which components of wellbeing are most strongly associated with cognitive function. Participants from the Midlife in the United States study (M_Age=56.18, SD=12.38) completed the Ryff Psychological Wellbeing Scales (1989) and the Brief Test of Adult Cognition. Multiple regression analyses were used to examine the cross-sectional and prospective associations between wellbeing and cognitive function. All six components of wellbeing were significantly and positively …

A Systematic Literature Review Of Behavior Analysis In Psychiatric Inpatient Settings, Stephanie Henry, Robbie Hanson

Theses

Applied behavior analysis (ABA) may be best known for the treatment of individuals with intellectual or developmental disabilities, such as those with autism spectrum disorder (ASD). However, ABA also has a long history of effective outcomes with other populations, such as with individuals who are admitted to inpatient psychiatric facilities (Dougher, 2004; Harvey et al., 2009). In 2018, 187,877 individuals in the United States were reported as receiving treatment for mental health disorders (Lutterman, 2022). Given behavior analysis’ success implementing operant procedures with these populations, an updated review of the literature on the use of behavior analysis within these settings …

Fit To Stay: Understanding The Impact Of Person-Group Fit On Transfer Intentions In College Sports, Marlee Johnson

All Theses

NCAA policy changes in 2021 regarding student-athlete transfer and external compensation have brought attention to the issue of turnover in college sports. Organizational psychologists have been studying turnover intentions and psychological antecedents of turnover intentions for years; however, little is known about the psychological variables that lead student-athletes to develop transfer intentions. The aim of this study was to explore the influence of both perceived supplementary and complementary person-group (PG) fit on student-athletes’ transfer intentions. It also examined affective commitment as a mediator between supplementary PG fit and intention to transfer and perceived team performance as a moderator in the …

The Impact Of Quality Of Life And Recovery Capital On Inhibitory Control In Patients On Medication For Opioid Use Disorder, Caroline K. Jeffries

All Theses

The opioid crisis persists as a global health challenge, necessitating a comprehensive understanding of the complex interplay between psychological factors and neurocognitive responses among individuals with opioid use disorder (OUD). Two such psychological factors include recovery capital, an individual's internal and external resources to supporting recovery, and quality of life. Past work suggests that positive levels of recovery capital and quality of life may enhance individuals’ ability to regulate emotions and manage cravings. However, it is unclear how these variables are affected when buprenorphine is taken. This study investigates the influence of recovery capital and quality of life on inhibitory …

Investigating Psychological Moderators Of The Effect Of A Slow-Paced Breathing Intervention On Decision-Making Performance, Anthony Alvarado

All Theses

Decision-making is a ubiquitous cognitive process that individuals engage in constantly—some decisions are inconsequential while others can have drastic implications. Identifying ways to improve decision-making, therefore, has potential to have lasting positive effects. One potential approach is slow-paced breathing interventions. While such interventions have shown promise for improving certain aspects of cognition, such as working memory, few studies have examined the effect of slow-paced breathing on decision-making performance. The current study sought to examine the effect of a brief slow-paced breathing intervention on performance on the Iowa Gambling Task (IGT), a reward-based decision-making task. Potential moderating variables such as stress, …

Social media has become increasingly popular among young adults, with some spending over 10 hours each day on social media. Social media can be utilized for community building, fostering relationships, providing safe spaces, inspiration, creative expression, and may even provide users with acceptance, validation, and a sense of belonging. Considering these factors, social media may also affect individuals negatively— specifically mental health-wise, in terms of anxiety and depression. This study aimed to identify whether a correlation exists between time spent on …

Proactive Leaders’ Development Of Employee Learning Goal Orientation And Voice In The Mitigation Of Work-Related Rumination, Iris Khan

Electronic Theses, Projects, and Dissertations

Work-related rumination aggravates stressors and demands at work. Past research has suggested that individuals with a learning goal orientation (LGO) cope better with ambiguity and challenges at work. Moreover, proactive leaders play an active role in influencing employees’ orientations and appraisals by modeling self-regulation through the encouragement of metacognition, employment of far-sighted goal-setting, and the utilization of participative behaviors like information-sharing that facilitates employees to take the initiative and adopt a more knowledge-seeking and developmental attitude towards their work. Using path modeling and confirmatory analysis, the study examined 1) whether the relationships between proactive leader behaviors and employee work-related rumination …

Voices From The Margins: Women Of Color On Diversity Policies And Workplace Culture, Aparna Kasturi

Electronic Theses, Projects, and Dissertations

Women of Color (WoC) in corporate leadership experience distinct problems that stem from the intersection of race, gender, and class. Despite the extensive implementation of diversity, equality, inclusion, and accessibility (DEIA) policies in companies, these initiatives often emphasize quantitative metrics over genuine lived experiences. Many of the DEIA policies seem cosmetic and do not tackle the fundamental challenges faced by WoC such as the "glass ceiling," "sticky floor," and exclusion from sponsorship networks; how the lack of an intersectional approach in policy development might overlook the subtle biases. By placing the voices and lived experiences of WoC at the center, …

An Analysis Of The Effects Of Embedded Instruction And Item Quality On Activity Selection, Julianne Isabella Fernandez

Theses and Dissertations

Naturalistic teaching strategies, such as embedded instruction, have been used to effectively teach a variety of skills to individuals diagnosed with ASD and other developmental disabilities. However, the effect of embedding instructions on a child’s play preferences is unknown. The goal of this study is to evaluate whether response allocation is dependent on frequency of demands or quality of items available during preferred activities. We used a concurrent operants arrangement in which a room was divided into two sides and various toys were placed in each with embedded demands available in one side. In Experiment 1, researchers evaluated the time …

The Effect Of Implementing A Development Program Using Mental Imagery On The Time To Master Psychomotor Skills, Randal Agee

Dissertations

Psychomotor skills development programs that use mental imagery have been demonstrated to help individuals acquire psychomotor skills (Anu et al., 2020; Seymore-Walsh et al., 2020; Toth et al., 2020). The commercial trucking industry is presently experiencing a global shortage of qualified truck drivers (American Trucking Association, 2019; Staats et al., 2017). One reason individuals are avoiding or leaving careers as commercial truck drivers is the time spent away from home (Staats et al., 2017). A couple logistical strategies have been developed to improve the situation (Mittal et al., 2018; Prime Inc, 2024); however, for the solutions to be sustainable, the …

The Drawing Effect: Evaluating Drawing Method And Strategic Implementation On Recall Accuracy, Jacob M. Namias

Dissertations

Drawing images of to-be-remembered word’s reference often improves memory for the word relative to a control in which the word is written or read silently, a pattern dubbed the drawing effect. Drawing effects have been recorded in a variety of contexts and are generally more beneficial than other deep/elaborative encoding tasks. My dissertation compared recall for words that are drawn by copying a given image versus generating a drawn image without copying, and in study contexts in which the proportion of drawn items is disproportionally skewed. Experiment 1 gauged whether drawing effects differ relative to writing when participants draw an …

Evaluating The Effects Of Social Ostracism On Attentional Control And Episodic Memory, Colby Brown

Honors Theses

This study examined the relationships between social pain, attentional control, and episodic memory. Fifty-five University of Southern Mississippi undergraduates (Mage = 19.78 years; Range = 17-29) wrote responses to one of three prompts designed to elicit feelings of social pain, physical pain, or no pain (i.e., control). Participants then completed a battery of attentional control (AC) and episodic memory (EM) tasks consisting of the Stroop squared, Flanker squared, Simon squared, and dual-list recall tasks. Participants also completed a series of questionnaires including Positive and Negative Affect Schedule (PANAS) to assess any change in affect caused by the writing prompts and …

Location Tracking Applications And Emerging Adult Relationship Quality: Moderated By Rejection Sensitivity, Michelle Lee Hayes

Walden Dissertations and Doctoral Studies

Location-tracking applications promise increased connection, safety, and closeness among romantic partners. However, persistent monitoring in romantic relationships has been associated with heightened feelings of intrusion and mistrust, particularly among individuals with insecure attachment. Such surveillance can exacerbate rejection sensitivity, leading to jealousy, conflict, and deteriorating relationship quality, or monitoring may alleviate fears of rejection and enhance relationship satisfaction. From the lens of attachment theory, this quantitative research study examined whether rejection sensitivity moderates the relationship between the use of location-tracking applications and relationship quality among emerging adults. I collected information from an online survey using four instruments to collect data …

Expediting Tool-Use Learning: Effects Of Non-Invasive Neurostimulation Of The Left Anterior Supramarginal Gyrus, Kamila Haliru

Honors Thesis

The left anterior supramarginal gyrus (aSMG) has been implicated as an important brain region in tool use. While anodal transcranial Direct Current Stimulation (atDCS) over the primary motor cortex (M1) has been shown to facilitate skilled tool use, the effects of aSMG stimulation remain largely unexplored. Using a chopstick-marble paradigm, this thesis examined whether atDCS to the left aSMG would enhance tool-use learning. Electroencephalography (EEG) was concurrently recorded to assess atDCS-dependent changes to the beta and gamma frequency bands. Our results demonstrated that atDCS over the left aSMG significantly expedited tool-use learning and was associated with increased gamma band activity …

Exposing The Truth Behind The Stanford Prison Experiment, Leo Novack

Young Historians Conference

In 1971 Philiip Zimbardo, a Stanford University professor, designed an experiment to study human behaviors in the prison system. He sought to understand the effectiveness of the prison system, however, the experiment ended early due to the ethical concerns toward participants. It is considered one of the most important psychological experiments, not for what it helped reform, but for what it pointed out about the importance of safety for research participants. Calling upon primary sources from participants and the researchers’ findings, as well as secondary sources primarily from psychologists and research ethics, the research reveals that this study was unreliable …

Understanding The Needs Of The Intellectually And Developmentally Disabled And Autistic Population In The Criminal Justice System, Emily Sateary

Master of Arts in Human Services

This paper explores the inequitable treatment of the Intellectually and Developmentally Disabled and Autistic (IDD/A) population in the criminal justice system. Although progress has been made over the past century with understanding the unique needs of this population, they still face challenges at all stages of the criminal justice system. Behavioral, social skills, and sensory challenges make it difficult for the IDD/A population to avoid criminal justice contact and to understand the criminal justice process. Insufficient training for police and attorneys harms both persons with IDD/A and criminal justice professionals. This paper examines current practices in place that are barriers …

Task Demands Influence Search Strategy Selection In Otoconia-Deficient Mice, Ryan M. Yoder, Lucas C. Carstensen, Keshav Jagannathan

Psychology

Introduction: The vestibular system plays a crucial role in visual and non-visual navigation. Our recent study found that signals from the otolith organs are necessary for mice’s use of distal visual cues to guide navigation to an invisible goal. Somewhat surprisingly, however, performance was not significantly impaired on some spatial tasks (e.g., Barnes maze reference memory task), questioning the role of otolith signals in visual navigation.

Methods: We report the results of several additional tests of reference memory performance and search strategy use on two versions of the Barnes maze, in an attempt to establish further understanding of the otolithic …

Honors Theses

The present thesis aims to determine the effects, if any, of six potential moderators on the effects of acute moderate-intensity exercise on cognitive functioning. The modes of exercise undertaken by the participants included treadmill (Experiment 1) and stationary bike (Experiment 2) exercise. Participants in each experiment either exercised or rested for twenty minutes and then participated in either a memory recall task or cognitive functioning (“Stroop”) task. The bouts of either exercise or rest on the stationary bike were followed by a rest period during which the participant would be exposed to either standard air oxygen levels (normoxia) or hypoxic …

Bedtime Or Game Time: The Impact Of Chronotype Matching On Spectators Moods, Callie Hart

Honors College Theses

Chronotypes have been shown to affect various aspects of life including health and day to day activities such as eating and exercising (Pacheco & Rehman, 2022). Research also indicates that chronotypes can have a direct impact on a person’s mood (Kim et al., 2021). The purpose of the current study was to examine the relationship between peoples’ chronotype and their mood at a sporting event. It was hypothesized that participants who attend the game at their preferred chronotype time will report being in a better mood and have higher levels of energy than if they attend a game that starts …

Life In Dance: Relationship To Self And Dance Environment, Emily Barz

Undergraduate Theses

Dance is an athletic art form in which the body is trained repetitively to perfect sequences of movement. The training regimen for dance requires a lot of time and dedication; this training can have an impact on self-esteem, especially when aspects of dance become detrimental to the dancer.

Maintaining a high level of self-esteem is important for dancers because self-esteem impacts a dancer's ability to grow in their artistry as well as life outcomes outside of dance.

Current research on dancer self-esteem highlights a very specific issue: body image. Dancers are expected to execute technique and fulfill high standards; oftentimes, …

Psychological Assessment Is Here To Stay, Irving B. Weiner

Archives of Assessment Psychology

Psychological assessment is based on the psychology of individual differences and dates back to the beginnings of scientific psychology. Clinical psychology began as a profession that provided psychological assessment, and through the 1950s assessment was what most clinical psychologists did most of the time. The value and propriety of psychological assessment was subsequently challenged on various grounds, and other activities gradually supplanted diagnostic testing as a preferred career role among clinical psychologists. Despite predictions of its demise, assessment has continued to be the second most frequent professional activity of clinical psychologists, after psychotherapy. Instead of fading away, psychological assessment has …

Archives of Assessment Psychology

Objective: To explore the psychometric properties of MMPI-adapted versions of the MMPI-2-RF’s RC and factor scales when applied to archival adolescent MMPI data. Method: We explored the internal consistency, temporal stability, and convergent and criterion validity of newly derived MMPI-adapted RC scales and MMPI-adapted higher-order factors (MMPI-ARC and MMPI-AF) using data from the first normative adolescent MMPI samples: 3,971 ninth graders assessed in Minneapolis public schools in 1947-1948 and 11,329 ninth graders assessed statewide in 1954. Results: Most MMPI-ARC and MMPI-AF scales showed good internal reliability, which did not vary uniformly with the proportion of available items. The MMPI-ARC scales …

Information Processing Theory (R.J. Lachman), Kimberly Diah, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

Information Processing Theory is a cognitive approach designed to understand human learning. Several perspectives of this theory emerged from the cognitive revolution in psychology beginning in the 1950s. The invention of the technological age of computers brought with it an innovative way of understanding how information is processed in humans. This lead researcher to draw analogies between the processing ability of humans and computers. The human-computer analogy developed from the foundation that as computers are able to process information so too can humans in a very similar method. Both encompasses ‘cognitive’ processes such as learning or obtaining information, solving problems, …
