Pushing It To The Limit: Determining Asian Elephant (Elephas Maximus) Olfactory Sensitivity And Discrimination Through A Behavioral Choice Task, Matthew S. Rudolph

Theses and Dissertations

Elephants have shown remarkable olfactory capabilities. Their sense of smell impacts their foraging choices, behavior, and ultimately, survival. Being able to detect a target odor can allow elephants to locate specific resources, identify threats, and find receptive conspecifics. Previous studies have shown that elephants can consistently detect target odors, but have not identified the limits of this detection. Thus, to investigate the extent of elephants’ odor detection capabilities, we tested Asian elephants in a two-step odor discrimination task. First, we investigated whether elephants could detect odors at varying levels of dilution after a training procedure, and then whether they could …

Discrete Processing In Visual Perception, Marshall L. Green

Theses and Dissertations

Two very different classes of theoretical models have been proposed to explain visual perception. One class of models assume that there is a point at which we become consciously aware of a stimulus, known as a threshold. This threshold is the foundation of discrete process models all of which describe an all-or-none transition between the mental state of perceiving a stimulus and the state of not perceiving a stimulus. In contrast, the other class of models assume that mental states change continuously. These continuous models are founded in signal detection theory and the more contemporary models in Bayesian inference frameworks. …

The Afro-Brazilian Martial Art Of Capoeira: Cultural Healing And Identity, Lauren Hsiao-Ling Mascari

Theses and Dissertations

By the year 2050, racial and ethnic minorities are projected to become the rising majority accounting for more than 50% of the population in the United States, however minorities are consistently at greater risk for poorer health outcomes and at higher risk for trauma-related symptoms than their White counterparts. Although some individuals seek and access traditional mental health services, more than half of the individuals who have diagnosable conditions never obtain formal treatment. Within the past two decades, the American Psychological Association delineated Multicultural Guidelines that describe the need for interventions to not only adapt to culture, but to be …

Examining Black Americans’ Attitude Towards Mental Health Treatment, Alannia Mosley

Theses and Dissertations

ABSTRACT

EXAMINING BLACK AMERICANS’ ATTITUDE TOWARDS MENTAL HEALTH TREATMENT

By

Alannia Mosley-Jenneford

The University of Wisconsin-Milwaukee, 2021 Under the Supervision of Marty Sapp, Ph.D.

The purpose of this study was to expand on the current literature on help-seeking attitudes among Black Americans. There is little research exploring the variables associated with Black American’s help-seeking attitudes. However, research has documented the underutilization of service among Black Americans. Literature suggests Black Americans do not seek services until symptoms become persistent and interfere with daily functioning. Evidence supports the relationship between help-seeking attitudes and racial mistrust, racial identity and help-seeking attitudes, and racial …

Behavioral And Neural Correlates Of Episodic Memory Regulation, Mrinmayi Kulkarni

Theses and Dissertations

Episodic memory retrieval, while critical for daily living, needs to be regulated to maintain goal-directed behavior. Past work has shown that episodic memory regulation engages brain regions involved in cognitive control, such as the dorsolateral and ventrolateral prefrontal cortex. These regions interact with the medial temporal lobe structures to control retrieval processes. In the current study, I paired eye-tracking, a sensitive index of memory, with fMRI in a novel paradigm to address several open questions in the field of episodic memory regulation. Participants initially encoded three celebrity faces and three tools with multiple indoor and outdoor scenes. In a subsequent …

Mental Health Stigma And Its Impact On Experiences Of Decent Work For Veterans, Matthew James Kessler

Theses and Dissertations

Veterans comprise roughly 8.3% of the U.S. adult population and 6.4% of the civilian labor force. Veterans tend to experience rates of both unemployment and underemployment at rates similar to their civilian peers. The duration of enlistment for military members has increased over the last four decades. Although longer enlistments may indicate better retention efforts and the ability to sustain individual careers in the military, this also increases potential rates for combat exposure and psychological distress. Additionally, military members tend to assume strong military identities through their time in the service.

Veterans often struggle with reintegrating into civilian life after …

Transition From Collegiate Track & Field: An Examination Of Values And Commitment, Michael Clark

Theses and Dissertations

This study provides a glimpse into psychological factors some of the 100,000 student-athletes who leave collegiate sport each year may face and adds to current understandings of ways to best serve collegiate student-athletes prior to their departure from collegiate sport. Drawing from the theories of Acceptance and Commitment Therapy and The Minnesota Theory of Work Adjustment, the study utilizes a population of former NCAA Division 1, 2, 3 and NAIA student-athletes to offer an in-depth look at the transition away from collegiate track and field. Mediation analysis was utilized to explore the interplay between commitment to values driven behavior, psychological …

Neural Correlates Underlying The Interactions Between Anxiety And Cannabis Use In Predicting Motor Response Inhibition, Richard Ward

Theses and Dissertations

The ability to effectively withhold an inappropriate response is a critical feature of cognitive control. Prior research indicates alterations in neural processes required for motor response inhibition in anxious individuals, including those with posttraumatic stress disorder (PTSD), and those who engage in regular cannabis use. However, thus far most research has examined how anxiety-related symptoms and cannabis use influence response inhibition in isolation of one another. The current study examined the interactions between anxious symptomology and recent cannabis use in a sample that recently experienced a traumatic event using functional magnetic resonance imaging (fMRI) during the completion of a Stop-Signal …

Suicide Attempt Types In College Students, Haley Pierson

Theses and Dissertations

Although suicide is now being the second leading cause of death in college and university students, there continues to be a lack of research examining the three types of suicide attempts (i.e., aborted, interrupted, and actual). Interrupted suicide attempts have been found to be predictive of death by suicide, and aborted suicide attempts have been found to be highly associated with an actual suicide attempt (Barber, Marzuk, Leon, & Portera, 1998; Steer, Beck, Garrison, & Lester, 1988). Research continues to suggest a lifetime number of suicide attempts is regarded as one of the strongest predictors of future suicide (Suominen et …

Thinking And Talking About Kinds, Ye Ji Seoung

Theses and Dissertations

Three experiments investigated whether definite singular generics (e.g., the dog barks) require that the kind does not contain multiple subkinds. No effect of generic form was found in experiment 1 and 3. However, experiment 2 found people thought there were fewer subkinds when definite singulars referred to the kind.

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.

Does Subjective Time Cost Explain Cognitive Task Choices?, Raina Ashley Isaacs

Theses and Dissertations

The current literature suggests that subjective time duration could be the common currency used for task choice. However, few studies have been conducted that use non-physical tasks for their task choice options. Thus, the purpose of the current study was to examine if subjective time duration is the common currency for task choice regardless of task type. Participants first provided their subjective time estimates for each of the perceptual-motor and cognitive tasks that have been a priori determined to be at the medium difficulty level. Two cognitive tasks (item generation and math problem task) and one perceptual-motor task with a …

A Conceptual Replication To Investigate The Hostile Priming Effect, Charlotte Basch

Theses and Dissertations

The current study attempts a conceptual replication of Srull and Wyer’s 1979 study on hostile priming as part of a large-scale replication. The current study did not find that participants who were exposed to the hostile phrases rated the individual as more hostile as the original study did.

Decent Work As A Moderator For Survivors Of Traumatic Life Events, Matthew Carbonelli

Theses and Dissertations

The Psychology of Working Theory (PWT) is a vocational psychology theory that aims to explore the pathways and outcomes that may hinder or improve the likelihood of obtaining decent work by including contextual factors such as marginalization and economic constraints. Vocational psychology primarily focuses on individual characterological elements of obtaining work; however, limited evidence exists exploring how traumatic symptoms or exposure may affect one’s abilities to find work. This study seeks to utilize PWT to understand better how the relationship between trauma exposure and job satisfaction and personal wellbeing is moderated by decent work. Sampling consisted of 61.3% female (n …

Effect Of Task-Irrelevant Emotional Faces On Attention To A Letter Search Task At High And Low Perceptual Loads, Nina Plotnikov

Theses and Dissertations

The attentional processing of emotional faces has interested researchers over the past thirty years. However, differing methodology has led to inconsistent findings. It has been suggested that using emotional faces as task-irrelevant distractors and varying perceptual load of the primary task can create an experimental framework that will allow attentional capture by emotional face processing to be better identified and differentiated from other processes. Furthermore, the effects of time on-task on attentional processing of emotional faces are currently not well understood, in part because traditional statistical analyses, such as the ANOVA, are insufficient for finding longitudinal trends in the data. …

Third Culture Kids - Playing To Heal, Amna Sana

Theses and Dissertations

With increased globalization and a large expat population, Qatar is home to increasing numbers of Third Culture Kids (TCKs). TCKs are children who live in a country where their parents are non-native, children who grow up between cultures. Young TCKs, especially children between the ages of three and seven, do not possess the skills to adequately vocalize their feelings, but fortunately, play therapy allows them to articulate problems and feelings on their own terms. This thesis addresses the emotional hurdles facing TCKs, using concepts derived from play therapy and offering a series of interactive objects designed to reflect emotional expression …
