Do Familiar Memory Items Decay?, Timothy J. Ricker, Joshua Sandry, Evie Vergauwe, Nelson Cowan

Department of Psychology Faculty Scholarship and Creative Works

There is a long-standing debate over whether the passage of time causes forgetting from working memory, a process called trace decay. Researchers providing evidence against the existence of trace decay generally study memory by presenting familiar verbal memory items for 1 s or more per memory item, during the study period. In contrast, researchers providing evidence for trace decay tend to use unfamiliar nonverbal memory items presented for 1 s or less per memory item, during the study period. Taken together, these investigations suggest that familiar items may not decay while unfamiliar items do decay. The availability of verbal rehearsal …

Who's Your Hoosier? How External Factors Affect Judgement When Choosing Romantic Partners At Indiana Colleges, Amanda Rosenfeld

Undergraduate Honors Thesis Collection

Most of the literature on online dating addresses what makes a profile more desirable. However, little research has been done examining why someone can be drawn to an adverse profile (i.e. a profile containing clear ’red-flag’ traits). This study will analyze how two types of external influence, recommendations provided by a computer algorithm and consensus information provided by peers, interact to affect judgement in the context of using a dating application to choose hypothetical romantic partners. The romantic experience level of each participant will also be analyzed to see if lack of experience moderates how much individuals rely on external …

Disordered Eating Habits, Emotion Regulation, And Theory Of Mind In Undergraduate Students, Brianna Borri

Undergraduate Honors Thesis Collection

Theory of Mind (ToM), the ability to recognize and attribute mental states to oneself and others, has been found to be impaired in a number of different psychological disorders (Bora et al. 2009). Evaluating ToM in a population suffering from eating disorders, however, has proven less consistent; some Anorexia Nervosa patients show ToM deficits compared to healthy controls (Russell et al. 2009) and others perform similarly (Tchanturia et al. 2004). A common consensus not only seems to be lacking within the literature on ToM and Anorexia Nervosa, but within the broader family of eating disorders as well (e.g., Bulimia Nervosa; …

What Do You Want To Be When You Grow Up? Cognitive Flexibility Influences Career Decision Making And Related Anxiety, Emily Flandermeyer

Undergraduate Honors Thesis Collection

Career indecision is a stage most individuals pass through during their lifetime, but it is often accompanied by anxiety. While anxiety can have a positive influence on decision making by focusing attention and cognitive resources, excess anxiety can disrupt the career decision-making process. Existing literature links anxiety to cognitive flexibility, an individual’s ability to efficiently switch between thoughts and ideas and adapt to evolving situations, with young adults higher in cognitive flexibility typically experiencing less anxiety than their less flexible peers. However, no studies to date have examined cognitive flexibility as it relates to career indecision or career-indecision-related anxiety. This …

E-Books: Cognitive And Visual Effects, Hannah Degroot

Undergraduate Honors Thesis Collection

Sight is incredibly important to daily life. One critical use of this sense is reading, which allows people to communicate and learn new things if the reader is able to effectively comprehend what he or she has read. The proliferation of technology has resulted in much of our reading today being done through digital media. Information-presenting screens are found nearly everywhere, including within the education system. While E-books can offer some advantages, their purpose would not be served if they hindered understanding. Additionally, excessive use of technological devices can bring about symptoms of eyestrain. It was hypothesized that E-books are …

Drinking In The Dark: Voluntary Co-Consumption Of Nicotine And Alcohol For Binge-Like Drinking Behavior In Mice, Katherine Benson

Undergraduate Honors Thesis Collection

Alcohol and nicotine are two of the most commonly abused drugs across the United States. Given the high rates of comorbidity, it remains a pressing public health concern to determine how the two drugs interact within the CNS, and how this impacts addictive behavior. The present study investigated the effect of comorbid abuse of nicotine and alcohol on stress and anxiety-like withdrawal symptoms, as both are associated with increased rates of relapse. A voluntary co­-consumption, two-bottle choice paradigm was used with nicotine and alcohol to induce binge-­like drinking behavior in mice following the drinking in the dark (DID) model of …

“Wide-Awake Drunk”: Observing The Combined Effects Of Alcohol And Caffeine On Somatic Withdrawal Signs In C57bl/6j Mice, Montana Jenkins

Undergraduate Honors Thesis Collection

Caffeine is one of the most widely used psychoactive stimulants in the world and is often used in combination with other substances. The combination of caffeine and alcohol has been shown to induce a stimulated, rather than sedated state, which may result in increased alcohol-attributable accidents (e.g., drunk driving, unprotected sex, and over intoxication). Preclinical research has found mixed results regarding the co-consumption of caffeine and alcohol – some found that caffeine increases alcohol intake while others the opposite. The current study expanded on previous research by testing the effects of combined caffeine and alcohol exposure in a binge-like, mouse …

Sex Differences In The Play Of African Elephant Calves (Loxodonta Africana) In Captivity, Samantha Ruppert

Undergraduate Honors Thesis Collection

African elephants (Loxodonta africana) live in a tiered society, with hundreds of elephants in a population (Moss, Croze, & Lee, 2011). Calves below eight years of age are within five meters of their mother 80% of the time, but spend a fair amount of time with other calves (Moss et al., 2011). Calf play in the first year of life includes: pushing each other’s heads (sparring), wrestling, and chasing. These activities prepare each sex for its adult role (Shoshani, 2000). I predicted that male and female calves would have different, but overlapping, behavioral repertoires and the behavior of elephant calves …

A Book And Its Cover: The Effects Of Dynamic And Static Facial Expressions On The Perction Of Personality Traits, Jonathan Ojeda

All Master's Theses

This study used three dynamic and three static images of older adult men depicting either smiling, scowling, or neutral facial expressions to examine the influence of motion on emotion identification and stereotype activation, specifically the Halo Effect, in older adults (55-85 years). To that end, two hypotheses emerged: 1) older adults will be more accurate in identifying facial expressions when viewing dynamic facial expressions than static facial expressions, and 2) participants exposed to the dynamic stimuli would experience greater levels of the Halo Effect with the greatest levels in the smiling facial expression condition. A 2 (stimulus type: dynamic and …

Worldview Conflict In Daily Life, Mark J. Brandt, Jarret T. Crawford, Daryl R. Vantongeren

Faculty Publications

Building on laboratory- and survey-based research probing the psychology of ideology and the experience of worldview conflict, we examined the association between worldview conflict and emotional reactions, psychological well-being, humanity esteem, and political ideology in everyday life using experience sampling. In three combined samples (total N = 328), experiencing disagreement compared to agreement was associated with experiencing more other-condemning emotions, less well-being, and less humanity esteem. There were no clear associations between experiencing disagreement and experiencing self-conscious emotions, positive emotions, and mental stress. None of the relationships were moderated by political ideology. These results both replicate and challenge findings from …

Storytelling Study, Samantha Irene Pepe

Honors Theses and Capstones

Expressive prosody (i.e., a manner of communication that is characterized by lively rhythm and tempo) and inexpressive prosody (i.e., monotone speech) present different environments for listening to a story during a read-aloud session. This study aims to assess whether there are visual attention differences for preschoolers in these varied prosodic environments and how this affects comprehension.

Impact Of Serratus Plane Block On Pain Scores And Incentive Spirometry Volumes After Chest Trauma, Nadia Hernandez, Johanna De Haan, Dallis Clendeninn, David E Meyer, Semhar Ghebremichael, Carlos Artime, George Williams, Holger Eltzschig, Sudipta Sen

Background: Adequate pain control is difficult to achieve in patients with multiple rib fractures (MRF). Serratus plane block (SPB) is a novel technique for alleviating rib fracture pain. Several published case reports support this hypothesis.

Purpose: The purpose of this study was to evaluate the use of SPB in MRF at our level 1 trauma center.

Methods: Our hospital’s Regional Anesthesia Registry was queried for all trauma patients with MRF who underwent SPB between August 2014 and January 2018. Data were compared in each patient as a matched pair for the time periods before and after undergoing SPB. Thirty-four patients …

Beyond The Cut: An Exploration Of Editing Techinques And Emotion, Kelly Santos

Whittier Scholars Program

Filmmaking is a production process that has been around for many years. Though our attention primarily focuses on the content shown, so much more occurs behind the scenes. The purpose of this research is to take a look at the art of film editing, specifically in terms of the elements and techniques that contribute to the overall creation of the cinematic experience, and how these aspects work to evoke emotions within an audience. Taking place in the post-production process, editing is essential to the creation of a film. The elements introduced in this paper bring understanding to the foundation of …

The Short Dark Triad And Giving To Nonprofits, Austin N. Prewett, Charles Elliott, Paul A. Story

The Kennesaw Journal of Undergraduate Research

The present study examines whether “demonstrable utility,” the belief that giving provides immediate or future tangible benefits (Sargeant, Ford, & West, 2006) significantly correlates to the adverse personality traits Machiavellianism and narcissism as they are defined in the Short Dark Triad (Paulhus & Williams, 2002). Two-hundred and twelve participants were gathered from Kennesaw State University to participate in a 20-minute online survey. While other factors were tested, attention was placed on demonstrable utility. Simple linear regression models were used to determine the relationship between demonstrable utility, Machiavellianism, and narcissism. A post-hoc Sobel’s mediation test was used to establish the different …

Approved Victim Contact And Treatment Outcomes Among Domestic Violence Offenders, Brian Timothy Longworth

Walden Dissertations and Doctoral Studies

Batterer intervention programs (BIPs) were developed to address high recidivism rates and low treatment completion rates in domestic violence offenders. Segregation between these offenders and their victims has been traditional in BIPs, but there has been no research exploring if this separation is related to treatment outcome. This research explored the relation between offender contact with their children or victims and outcomes including recidivism and treatment completion. Most domestic violence interventions are psychoeducational in nature and are based on the cognitive behavioral theory premise that if an individual'€™s thinking process can be changed, a change in actions can result. This …

Attitudes And Perceptions Among African Americans About Dating Individuals With Bipolar Disorder, Casey Michelle Johnson

Walden Dissertations and Doctoral Studies

The purpose of this generic qualitative study was to examine the attitudes and perceptions of African American men and women regarding their experiences of dating and relationships with individuals who suffer from bipolar disorder. The theory used in this study was equity theory. The research question for this study explored how African American adults experience relationship acquisition and maintenance with a partner who has been diagnosed with bipolar disorder. For this generic qualitative study, there were 12 respondents. Participants were …

Impact Of Work-Related Electronic Communications Behavior Outside Of Normal Working Hours, Beulah Lavell Williams

Walden Dissertations and Doctoral Studies

Employers' reliance on asynchronous electronic communications, connective technology devices, and remote work arrangements has led employees to feel preoccupied with staying connected after-hours to be responsive to work-related demands. The purpose of this transcendental phenomenological study was to describe the lived experiences of professional workers who coped with constant pressure to monitor and immediately respond to work-related electronic communications during nonwork hours. The conceptual framework was supported by boundary and border theory and the constructs of work-life balance, flexible work arrangements, information and communication technology. Data were collected using semistructured interviews with 16 professional workers near Washington, DC. Moustakas's modified …

Experiences Of Young Homeless Adults In Transitional Housing, Cornelia Edoh

Walden Dissertations and Doctoral Studies

Homelessness continues to be a major and a comprehensive issue facing the United States, and it is a broad concern when it affects young adults. Research on the way individuals who are homeless perceive shelters, transitional programs, and housing program in general has been limited. Transitional living programs deliver critically needed temporary services for vulnerable and disadvantaged populations and provide them with the skills and the experiences needed to become independent. The study used a phenomenological design to explore the experiences of young homeless adults who are using transitional housing. The findings of this study may help young adults to …

Rural Transgender And Gender-Nonconforming Individuals' Experiences With Social Media During Adolescence, Heather Lynn Anderson

Walden Dissertations and Doctoral Studies

Suicide attempt and completion rates are significantly higher for the transgender and gender-nonconforming (TGNC) population. TGNC adolescents experience many challenges and adversities, which are compounded when they live in rural communities. The lived experiences of rural TGNC adolescents with social media were unknown and created a gap in the research. This study was grounded in transgender, gender minority stress, and resiliency theories, along with the conceptual frameworks of rural communities and grit. The purpose of this descriptive phenomenological qualitative research study was to explore the lived experiences of rural TGNC individuals (18-24-year-olds) with social media during adolescence. Data was collected …

Factors Associated With Parental Involvement In Their Child's Education, John Joseph Trentalange

Walden Dissertations and Doctoral Studies

After 4 decades and a large body of research on children's academic success, there is still a need to understand how to increase children's academic performance. Researchers agree that the key component to elementary school children's academic success is parental involvement. However, little is known on how to increase parental involvement and the characteristics of the parents who participate in their children's education. This quantitative study examined 2 parental characteristics, parents' internal attachment patterns and parenting styles, and their relationship with parental involvement and children's academic success. Bowlby's theory of attachment and Baumrind's parenting typologies served as the theoretical framework. …

Bet You Can’T Eat Just One: Binge Eating Disorder Promotion In American Food Advertising, Debbie Danowski

Communication, Media & The Arts Faculty Publications

"Eat Like Andy“; "What Would You Do For A Klondike Bar?“ For well over a century, American food manufacturers have been competing for consumers’ attention through the use of catchy jingles, iconic characters and celebrities. At the same time, the products being advertised contain greater amounts of addictive ingredients, which encourage binge eating resulting in an unprecedented obesity epidemic. Combine this with the full-scale commercialization of the culture today“. Jhally identifies and the powerful impact of food advertisements becomes clear as does the need to evaluate these ads. As Kilbourne noted nearly a quarter of a century ago, the majority …

Generosity In Gaming: The Effect Of Prosocial Video Games On Charitable Donation Behavior, Ethan Tom

CMC Senior Theses

Although the link between violent video games and aggressive behavior has received extensive coverage, there is growing evidence that prosocial video games can exert a positive influence as well. However, whether these effects generalize to costlier prosocial behaviors that help more distant recipients remains unclear. Here I propose an experimental study to examine whether prosocial video games can influence charitable donation behavior. College students will be randomly assigned to play 45 min of either a prosocial video game (Lemmings) or neutral video game (Tetris), followed by a 10 min filler task (mental calculation). Participants will then …

Evaluating The Relationship Between Depression, Perceived Stress, Sleep Quality, And Lure Discrimination, Jessica Rothberg

Theses, Dissertations and Culminating Projects

Depression, Stress and disordered sleep have been found to negatively affect cognition. However, the specific mechanisms affected are still unclear. These clinical symptoms are all independently associated with the hippocampus, where a memory process called pattern separation is assumed to occur. The current study aimed to further investigate the association between depression and pattern separation by further examining the role that sleep and stress play in this relationship. This study is an expansion from Shelton and Kirwan (2013) where they used the Mnemonic Similarities Task to evaluate lure discrimination and depression. I expanded on this by also evaluating sleep quality …

The Influence Of Meaningful Work On Marital Satisfaction In Dual-Earner Couples With Family Meaning As A Moderator, Nicole Conklin

Theses, Dissertations and Culminating Projects

The purpose of our study was to empirically investigate how individuals’ meaningfulness of work (MOW) is positively related to marital satisfaction of his or her spouse, and how meaningfulness of family (MOF) may moderate this relationship. Our sample consisted of dual earning couples with children, which allowed for data analysis through the Actor- Partner Interdependence Model (APIM), and Actor-Partner Interdependence Moderation Model (APIMoM). As hypothesized, there were actor and partner effects; individuals who experienced higher MOW reported higher marital satisfaction and higher MOW for individual’s predicted higher levels of their spouse’s marital satisfaction. Hypothesis 2a and 2b were also supported; …

The Effects Of Parental Divorce And Remarriage On Emerging Adult’S Romantic Attachment Styles, Bailey Mortis

Theses and Dissertations--Family Sciences

This study shined light on the gap in literature about the impact of communication and involvement of stepparents has on emerging adult’s romantic attachment styles. A sample of 289 college students between the ages of 18 and 22 at the University of Kentucky was recruited to complete an online survey about their perceived experience with their stepparent and parental figures and the effects on their romantic attachment styles. Parental involvement in children’s lives and having good communication, sets the foundation for individuals to have secure attachment styles. Emerging adults who experience parental figures and stepparents as being uninterested or passive …

Ayahuasca's Antidepressant Effects Covary With Behavioral Activation As Well As Mindfulness, Maha N. Mian

Legacy Theses & Dissertations (2009 - 2024)

Ayahuasca, a plant-based hallucinogen that serves as a spiritual medicine in South America, has improved depression in at least one placebo-controlled clinical trial. Case studies suggest that dramatic behavioral changes often follow the Ayahuasca ceremony, but most explanations of antidepressant effects focus on observed changes in mindfulness. The present study investigated if both mindfulness and behavioral activation might also contribute to these anti-depressant effects. We surveyed individuals (N = 152) about their changes in depressive symptoms, Behavioral Activation, and mindfulness after an Ayahuasca experience. Mindfulness was strongly associated with reduced depression severity (r = -.670, p < .001), while behavioral activation was moderately linked (r = -.474, p < .001). Changes in depressive symptoms (Center for Epidemiological Sciences Depression Short Form [CES-D-10]) covaried with subscales from the Five Facet Mindfulness Questionnaire [FFMQ] and Experiences Questionnaire [EQ], confirming previous findings (beta = -.57, [95% CI (- 5.70) - (- 3.25)], p < .001). In addition, a modification of the Behavioral Activation for Depression Scale-Short Form [BADS-SF] accounted for significant unique variance in the improvements in depression (beta = -.16, [95% CI (-6.32) - (-0.08)], p < .05). These results suggest that changes in behavioral activation likely serve as an important mechanism underlying Ayahuasca’s antidepressant effects. Future clinical trials could benefit from tracking behavioral activation. In addition, a concerted focus on increasing valued, positive activities might enhance Ayahuasca’s anti-depressant effects.

Classification Of Major Depression In College Students : A Grade Of Membership Analysis, Ishani Ravindra Deo

Legacy Theses & Dissertations (2009 - 2024)

The disease burden of major depressive disorder is at its greatest among college-aged individuals, and frequently leads to long-term negative outcomes. However, within and across racial/ethnic groups, there are significant differences in how the disorder manifests and the resulting impact. Conceptualizing depression in a way that accurately reflects this variation is therefore a crucial task. In the current study, grade of membership (GoM) analyses were used to derive “fuzzy set” depression profiles in a college sample for each of the five major racial/ethnic groups in the United States. The primary sample consisted of 22,778 European, African, Hispanic/Latino, Asian/Pacific Islander, and …

Learning A New Physics Concept By Exploring Analogous Problems : An Instructional Intervention, Joanna Perry Weaver

Legacy Theses & Dissertations (2009 - 2024)

This study tested the hypothesis that exploratory learning, with and without analogous problems, would improve students’ ability to make connections between conceptually-related topics. In this randomized experiment, undergraduates in introductory physics (N = 171) studied a new topic under three different instructional conditions. Order and type of instruction varied: Two experimental groups explored the concept before hearing a lecture; a control group followed the typical sequence of hearing a lecture before working with the concept. Within the experimental condition, students in the analogy-first group simultaneously explored analogous problems; students in the explore-first group explored only the new problem with a …

Eye Movements Reveal The Visual Component Of Music Expertise : Evidence From A Visual Search Task, Kinnera Savitri Maturi

Legacy Theses & Dissertations (2009 - 2024)

An important component of expertise is the ability to rapidly recognize domain-related perceptual patterns. To explore this ability in the domain of music reading, a unique visual search paradigm was used to compare the eye movements of 30 expert musicians (with at least 10 years of music reading skill) and 30 novices (who could not read music). Participants had to match a section of a piece of sheet music (search template) to its identical counterpart within a larger music score (search array). Both the search template and array were presented on the screen simultaneously, which allowed for visual comparisons between …

Does Testing Episodic "Lion-Tiger" And/Or "Tiger-Stripes" Associations Facilitate Later "Lion-Stripes" Learning, Deana Vitrano

Legacy Theses & Dissertations (2009 - 2024)

The current experiments examined Pyc and Rawson’s (2010) mediator effectiveness hypothesis (MEH) as one potential explanation of the beneficial effects of testing relative to restudying in paired-associate learning. In two experiments, participants learned cue-mediator-target triads (e.g., lion-tiger-stripes) broken down into separate components. Specifically, participants learned and then restudied or were tested on cue-mediator (List 1) and mediator-target (List 2) word pairs in Session 1, and in a Session 2 given 48 hours later learned cue-target (List 3) word pairs. According to Pyc and Rawson, compared to restudying, testing on List 1 cue-mediator and List 2 mediator-target word pairs should lead …
