Psychology Faculty Research and Publications

Background:

Body mass index (BMI) has been identified as an important modifiable lifestyle risk factor for dementia, but less is known about how BMI might interact with Apolipoprotein E ɛ4 (APOE ɛ4) carrier status to predict conversion to mild cognitive impairment (MCI) and dementia.

Objective:

The aim of this study was to investigate the interaction between APOE ɛ4 status and baseline (_bBMI) and five-year BMI change (ΔBMI) on conversion to MCI or dementia in initially cognitively healthy older adults.

Methods:

The associations between _bBMI, ΔBMI, APOE ɛ4 status, and conversion to MCI or …

Identifying Subtypes Of Trichotillomania (Hair Pulling Disorder) And Excoriation (Skin Picking) Disorder Using Mixture Modeling In A Multicenter Sample, Jon E. Grant, Tara S. Peris, Emily J. Ricketts, Christine Lochner, Dan J. Stein, Jan Stochl, Samuel R. Chamberlain, Jeremiah M. Scharf, Darin D. Dougherty, Douglas W. Woods, John Piacentini, Nancy Keuthen

Psychology Faculty Research and Publications

Body-focused repetitive behavior disorders (BFRBs) include Trichotillomania (TTM; Hair pulling disorder) and Excoriation (Skin Picking) Disorder (SPD). These conditions are prevalent, highly heterogeneous, under-researched, and under-treated. In order for progress to be made in optimally classifying and treating these conditions, it is necessary to identify meaningful subtypes. 279 adults (100 with TTM, 81 with SPD, 40 with both TTM and SPD, and 58 controls) were recruited for an international, multi-center between-group comparison using mixture modeling, with stringent correction for multiple comparisons. The main outcome measure was to examine distinct subtypes (aka latent classes) across all study participants using item-level data …

Developmental Dyslexia And Creativity: A Meta-Analysis, Nadyannam M. Majeed, Andree Hartanto, Jacinth J. X. Tan

Research Collection School of Social Sciences

Despite difficulties in reading and writing, some research suggests that dyslexia may be related to higher levels of creativity. However, this pattern is not consistently observed. The current research sought to ascertain whether individuals with clinically diagnosed dyslexia exhibit higher creativity than controls through a meta-analysis. Fourteen studies that assessed the creativity of 397 individuals with clinically diagnosed dyslexia and 453 controls were reviewed. Random-effects meta-analysis revealed an overall non-significant difference in creativity scores between those with dyslexia and controls. Additionally, method factors such as the type of creativity task and whether intelligence was controlled for, as well as sample-related …

Roboethics In Covid-19: A Case Study In Dentistry, Wendy C. Birmingham, Yaser Maddahi, Maryam Kalvandi, Sofya Langman, Nicole Capicotto, Kourosh Zareinia

Faculty Publications

The COVID-19 pandemic has caused dramatic effects on the healthcare system, businesses, and education. In many countries, businesses were shut down, universities and schools had to cancel in-person classes, and many workers had to work remotely and socially distance in order to prevent the spread of the virus. These measures opened the door for technologies such as robotics and artificial intelligence to play an important role in minimizing the negative effects of such closures. There have been many efforts in the design and development of robotic systems for applications such as disinfection and eldercare. Healthcare education has seen a lot …

This qualitative work reviews relevant literature, defines research questions for this research, details the methodology used to obtain data, describes the sample from which these data were obtained, and reports the results. Thematic analysis of narratives obtained in this qualitative study provides an enriched understanding of spiritual coping with life stressors that is useful for practitioners of clinical and pastoral counseling.

Freedom, Covid-19, And Resistance To Public Health Orders, Benjamin Rosenberg

Psychology | Faculty Scholarship

As we look back on one year since the first Covid-19 lockdowns went into effect in the United States, several truths about this ever-changing virus have emerged. For one, well-fitting, multi-layered face masks significantly reduce people’s likelihood of spreading or catching Covid-19 (e.g., Leung et al., 2020), and the vaccines similarly reduce the risk of spread and infection (Thompson et al., 2021). Second, things that were, at best, at the outskirts of people’s attention have become commonplace over the past year: hand sanitizer, social distancing, mask wearing, vaccinations. The related third truth is that over the past year, most Americans …

Black-Capped Chickadee (Parus Atricapillus) Food Preference, Isabelle Gilbert

Thinking Matters Symposium

All animals must make decisions on where to find, select, capture, and eat food. These factors contribute to a species’ food preference, such as making decisions on what food to eat based on calories. Optimal foraging theory predicts how an animal behaves when searching for food, including optimization of food type, patch choice, time spent in patches, and movement. All animals also make decisions based on predation risk by avoiding predators and making trade-offs on time spent searching for, pursuing, and handling food. The objective of my study is to examine food preference of black-capped chickadees (Parus atricapillus). Birds may …

Assessing Rat Behavioral Response To Novelty, Neha Mathew

Honors Scholar Theses

The hippocampus is the part of the brain that is involved in memory and navigation. Neurons in the hippocampus, known as place cells, fire in specific locations within this region of the brain as the subject navigates through their environment. As these cells fire, they create a map-like representation of this environment. However if the environment is altered in any way, the place cell firing pattern is adjusted to incorporate this new information. This adjustment will inevitably cause subjects to take more time to complete their task. The goal of our testing was to assess how various manipulations, both spatial …

Exploring The Relationships Between Community Experiences And Well-Being Among Youth Experiencing Homelessness, Katricia Stewart

Dissertations and Theses

The current dissertation presents two published empirical studies and one new study informed by the findings and recommendations of the first two. The first study investigated how intrapersonal factors (self-esteem, psychological distress, and optimism) and social-contextual factors (social support, sense of community, and empowerment) relate to the psychological well-being of 100 youth experiencing homelessness. The results indicated that all six variables were significantly related to well-being, but the intrapersonal factors had a stronger association with psychological well-being than the social-contextual factors. The second manuscript is a qualitative study investigating what community means to youth experiencing homelessness, what communities they are …

The Effects Of Acute Exercise On Retrieval Induced Forgetting, Walter Simpson

Honors Theses

Retrieval Induced Forgetting (RIF) is a type of active forgetting that may play beneficial and detrimental roles in long-term memory. The benefit of the retrieval of certain information is that information will become more readily available following subsequent retrieval; a concept termed the retrieval practice effect (RP). The detrimental effect of RIF may be that, upon the subsequent recall of certain information, related information may be inhibited from recall. The effects and mechanisms of RIF have remained a topic of debate among neuroscientists, psychologists, and other related scholars. The goal of this study was to evaluate the effects of acute …

Observation And Detection Of Adhd Malingering In College Students, Zoe Tenner

Honors Theses

The rate of college students attempting to obtain Attention-Deficit/Hyperactivity Disorder (ADHD) diagnoses in order to gain access to prescription stimulant medications has shown a large increase over the past 20 years. Research has also shown that college students are frequently able to convincingly present themselves as meeting clinical criteria for ADHD with relative ease, meaning that the barrier to false presentation for the purpose of obtaining inappropriately prescribed medication is minimal. There is a need for more concise, accurate tools to detect these efforts in clinical settings, which is an area of research pursued by members of the University of …

“Ichachu”: Ontological Diversity For Assembling Common Futures, Kaliana Conesa

The International Journal of Ecopsychology (IJE)

The present work explores the role of discursive analyses of language as potent elements in networks of discourse and practice. A particular focus is with how language functions in multiple, overlapping registers, and how this affects its ability to motivate and coalesce diverse actors into communities of practice. In particular, usages of sovereignty, food sovereignty, and ontology are explored as a means for understanding the process of cross-cultural eco-social action. Fundamental to these analyses is the precept that registers of language represent an epistemic diversity always operating in collaborations for biocultural sustainability. By “eco-social action,” it is meant any practice, …

Plastic Shamans, Intellectual Colonialism And Intellectual Appropriation In New Age Movements, Joseba I. Arregi Phd

The International Journal of Ecopsychology (IJE)

The reality of colonialism plagues indigenous populations and continues into the present, generating new scenarios of oppression. This new oppression is tied to so-called alternative models of progress, to the success of sustainable development, and to the recognition of the importance of biodiversity in the 21^st Century. This work presents three processes of biological and cultural appropriation which constitute a new chapter in the long history of colonial aggression and indigenous resistance.

Examining Bystander Blame In Rape And Sexual Assault, Katherine E. Purdom

Honors Theses

The present study investigated the effect of various factors on blame distribution in sexual violence cases. Participants (N = 378) were randomly assigned to either a rape (N = 187) or sexual assault (N = 190) condition and directed to read a scenario that varied only by the terminology indicated by the condition. Participants were provided two pre-filled slots labeled as the perpetrator and victim. Additionally, they were given two blank “free-response” options in which participants could assign blame and indicate a responsible party if they found it necessary. Data was gathered from the male (N = 163) and female …

The Influence Of Mental Fatigue On Sessional Ratings Of Perceived Exertion In Elite Open And Closed Skill Sports Athletes, Joseph O. C. Coyne, Aaron J. Coutts, Robert U. Newton, G. Gregory Haff

The influence of mental fatigue on sessional ratings of perceived exertion in elite open and closed skill sports athletes. J Strength Cond Res 35(4): 963-969, 2021-The main purpose of this investigation was to examine influence of mental fatigue on sessional ratings of perceived exertion (sRPE) over a training week in elite athletes in open skill (OS, i.e., more unpredictable and externally paced sports) and closed skill (CS, i.e., more predictable and internally paced) sports. Visual analogue scales for mental fatigue, sRPE (CR-10 scale), and training duration were collected from an OS group (n = 27) of basketball and volleyball athletes …

Pilot Analysis Of The Contemporary Beliefs And Identity Inventory, Kathleen Moser, Shelby Kreglow, Stevie N. Grassetti, Caroline Guzi

Psychology Student Work

Background: Feminism is a social movement that advocates for the protection and implementation of policies that promote gender equality. In one study of 116 master’s program students, 42 percent identified as feminist (Charter, 2015). Although little variation was detected between genders, only 6% of participants were male; this disparity is seen in much of the feminism research published today (Rickard, 1987; Bargad, & Hyde 1991, Fischer et al. 2000). The support of people who do not identify as women is imperative to advancing feminist ideals (Precopio, & Ramsey, 2017). While many non-women may support feminist views, measures of feminist identity …

Effects Of 3,4-Methamphetamine On Cognitive Empathy In Participants With Antisocial Personality Disorder, Emily P. Bosiacki

Psychology Student Scholarship

Emily Bosiacki ’21
Majors: Biology and Psychology
Faculty Mentor: Dr. Victoria Templer, Psychology

3,4-Methamphetamine (METH) has not been studied as a treatment method for people who have Antisocial Personality Disorder (ASPD). ASPD is mainly characterized by a lack of cognitive and emotional empathy. Previous research expresses that emotional empathy is achievable through drug treatment with empathogens such as ecstacy and psilocybin, but there has been no successful treatment to improve cognitive empathy. METH has not been used in previous research due it being very addictive and detrimental to cognitive function if taken at high levels over an extended period of …

Can Altering The Gut Microbiome Via Diet Treat Symptoms Of Major Depressive Disorder?, Julia Degrooth

Psychology Student Scholarship

Majors: Biology and Psychology
Faculty Mentor: Dr. Victoria Templer, Psychology

Due to the prevalence of Major Depression worldwide, researchers have begun to search for alternative treatment methods other than antidepressants. Previous studies have shown that depression is affected by the gut microbiota, but the actual composition of the gut in Major Depressive Disorder (MDD) is not well understood. Here, I analyzed fecal samples of 100 participants with MDD and 100 healthy controls. One hundred people from the control and experiment groups were randomly and equally assigned to either a Mediterranean diet or a Western diet. According to previous research, fecal …

The Impact Of Long-Term Social Housing On Biconditional Association Task Performance And Neuron Ensembles In The Anterior Cingulate Cortex And Ca3, Anne Dankert

Psychology Student Scholarship

Majors: Biology and Psychology
Faculty Mentor: Dr. Victoria Templer, Psychology Cognitive decline and neuronal activity changes are hallmarks of advancing age across species. Positive social relationships have been correlated with fewer age-related cognitive difficulties in humans. However, the mechanisms by which sociality might protect against cognitive aging and if this can be modeled in a rodent model remain unknown. We investigated differences in accuracy on a biconditional association task, which measures cognitive flexibility, and corresponding neuronal activity in the Anterior Cingulate Cortex and CA3 of the hippocampus between socially and nonsocially housed aged rats and individually housed young controls. Findings …

Effect Of Neurosteroid Levels, Genetic Linkages, And Pre-Deployment Virtualreality Resilience Training On Ptsd Severity, Kathryn Fama

Psychology Student Scholarship

Majors: Biology
Faculty Mentor: Dr. Victoria Templer, Psychology

Though Post-Traumatic Stress Disorder (PTSD) is a common problem among soldiers, current military programs focus on treating PTSD after combat deployment instead of preventing it. The aim of this project was to examine the neurosteroids allopregnanolone and pregnanolone (together known as ALLO), the SNP rs717947, and pre-deployment virtual-reality resilience training (VRRT) to identify effective PTSD prevention methods. Pre-deployment, a Brigade Combat Team (N=3000) of active-duty US Army soldiers was divided into two groups, a VRRT group and an online tactical training sessions (control) group. Soldiers’ blood plasma levels of ALLO were also …

The Impact Of Location And Time Of Day On The Expression Of Social And Physical Maintenance Behaviors In Wild Asian Elephants (Elephas Maximus) In Thailand, Summer Fiori

Theses and Dissertations

Much of what we know about Asian elephant (Elephas maximus) behavioral ecology is the result of long-term ethological studies on wild elephants in India and Sri Lanka or experimental research on captive elephant behavior and cognition. While it is important to study the behavior and ecology of elephants to understand the evolution of adaptations that have made them well-suited for their natural environments, there is also a growing need to study populations of wild Asian elephants for applied conservation purposes. More specifically, elephants are endangered and are facing increasing threats such as human-elephant conflict. In this study, behavioral data …

Representation Of Sex-Linked Properties: Implications For Conceptual Representation And Generics, Olga A. Leus

Theses and Dissertations

Four experiments provide evidence that we represent principled connections between kinds and sex-linked properties such that one type of instance of the kind has a principled connection for the presence of the property and the other type has a principled connection for the absence of that property.

Investigating Social Preferences In A High Fission-Fusion Society Of Black And White Ruffed Lemur (Varecia Variegata), Patricia A. Adamo

Theses and Dissertations

Wild lemur primates were tested for social preferences across behaviors. Study found highly conservative social preferences that were very consistent across all behavioral states, despite high fission fusion traits common of lemur groups. This finding lays the foundation for using nearest-neighbor as a proxy of social preference for future endeavors.

The Neurobiological Relationship Between Childhood Maltreatment And Major Depressive Disorder (Mdd), Morgan Clinton

Global Tides

Childhood maltreatment compromises healthy development, impacts neurobiology, and is associated with lasting alterations to emotional perception, processing, and regulation. Most significantly, childhood maltreatment increases the risk for later development of emotional disorders such as major depressive disorder (MDD). The stress associated with both childhood maltreatment and MDD can lead to lasting alterations to the fronto-limbic circuitry. Using functional and structural magnetic resonance imaging, researchers have observed hippocampal atrophy and amygdala hyperresponsiveness in participants who’ve experienced both childhood maltreatment and MDD. Furthermore, researchers have also observed increased connectivity between the hippocampus and amygdala in victims of childhood maltreatment. Because childhood maltreatment …

Evaluating A Game Designed To Teach Gender Bias, Jessica Frame

Undergraduate Research Conference at Missouri S&T

Gender bias is prevalent in today's work force; while it doesn't look like it did a few decades ago, it is still very critical to detect and address it. With how unconscious and covert gender bias can be, it is difficult to teach in a normal environment without some backlash and varying information due to teaching styles, leading to differed outcomes of processing information. The WAGES Project, WAGES standing for Workshop Activity for Gender Equity Simulation, is an interactive research-based activity that showcases how gender bias within the workforce is relevant in a manner different than that of a basic …

Everyday Memory In People With Down Syndrome, Yingying Jennifer Yang, Zachary M. Himmelberger, Trent Robinson, Megan Davis, Frances Conners, Edward Merrill

Department of Psychology Faculty Scholarship and Creative Works

Although memory functions in people with Down Syndrome (DS) have been studied extensively, how well people with DS remember things about everyday life is not well understood. In the current study, 31 adolescents/young adults with DS and 26 with intellectual disabilities (ID) of mixed etiology (not DS) participated. They completed an everyday memory questionnaire about personal facts and recent events (e.g., school name, breakfast). They also completed a standard laboratory task of verbal long-term memory (LTM) where they recalled a list of unrelated words over trials. Results did not indicate impaired everyday memory, but impaired verbal LTM, in people with …

What Is The Readiness Potential?, Aaron Schurger, Pengbo 'Ben' Hu, Joanna Pak, Adina L. Roskies

Psychology Faculty Articles and Research

The readiness potential (RP) has been widely interpreted to indicate preparation for movement and is used to argue that our brains decide before we do. It thus has been a fulcrum for discussion about the neuroscience of free will.

Recent computational models provide an alternative framework for thinking about the significance of the RP, suggesting instead that the RP is a natural result of the operation of a stochastic accumulator process of decision-making, analyzed by time-locking to threshold-crossing events.

These models call for a reevaluation of: (i) the ontological standing of the RP as reflecting a real, causally efficacious signal …

Body States Of Asian Elephants Within And Around Protected Areas In The Salakpra Wildlife Sanctuary, Kanchanaburi, Thailand, Caitlyn Thai

Theses and Dissertations

Researchers are becoming increasingly aware that studying a species’ landscape of fear or, more broadly, their emotional states, can better inform cognitive questions about how animals navigate their environments. Vigilance behaviors are one way to determine how certain species perceive and respond to risky situations. Due to rapid environmental change, large animals such as elephants are experiencing risky encounters with humans more often than ever before. This study aims to investigate Asian elephants’ expressions of body states and how they might regulate their behavior based on perceived environmental risk or change. Specifically, we investigated the behavioral responses of Asian elephants …
