Equine Assisted Psychotherapy: A Transformational Path To Emotional Wellness For U.S. Military Veterans, Cathy Powalski

Dissertations

Purpose. The purpose of this qualitative multiple case study was to explore and describe the impact of Equine Assisted Psychotherapy (EAP) on the reintegration of wounded veterans into civilian life as perceived by wounded U.S. military veterans participating in EAP.

Methodology. A qualitative multiple case study methodology was appropriate for this research due to its focus on analyzing a single entity (EAP) possessing unique characteristics within a system bound by participants (wounded U.S. military veterans as defined by this study), time (2015-2017), and/or place (California or Virginia) through events.

Findings. The 13 U.S. military veterans who participated in this study …

Time Delay And Investment Decisions: Evidence From An Experiment In Tanzania, Plamen Nikolov

Economics Faculty Scholarship

Attitudes toward risk underlie virtually every important economic decision an individual makes. In this experimental study, I examine how introducing a time delay into the execution of an investment plan influences individuals’ risk preferences. The field experiment proceeded in three stages: a decision stage, an execution stage and a payout stage. At the outset, in the Decision Stage (Stage 1), each subject was asked to make an investment plan by splitting a monetary investment amount between a risky asset and a safe asset. Subjects were informed that the investment plans they made in the Decision Stage are binding and will …

Binocular Rivalry Of Emotional Expressions, Daniel Stephen Lumian

Electronic Theses and Dissertations

A central debate in defining emotional space is whether emotions are organized categorically (e.g., fear, happy, disgust) or continuously (i.e., along the independent dimensions of valence and arousal). Emotional facial expressions are one tool often leveraged in trying to define emotional space. Faces are rich sources of social and emotional information. Faces, like emotions, can be organized in either categorical (e.g., happy, sad) or continuous (e.g., open-closed) ways. Therefore, understanding the relatedness of emotional facial expressions to each other may shed light on the underlying structure of emotions. Binocular rivalry (BR) is a tool which can be leveraged to measure …

Symmetry Identified In 2-Dimensional Artwork Compositions Using Visuospatial Ability, Theresa Ferg

Electronic Theses and Dissertations

At the John Langdon Down Foundation A.C. in the La Escuela Mexicana de Arte Down school in Mexico City D.F., Mexico, art students with Trisomy 21 display the use of a mathematical construct in the painting compositions of their artworks. The mathematical construct is a type of symmetry and it carries a positive affect. This is important because there have been no studies that have investigated the use of the symmetry in the artwork compositions of persons with Down syndrome. The geometric construction of the artwork compositions follows the artistic principle of the Rule of Three and the division of …

Gene × Environment Interaction: What Exactly Are We Talking About?, David S. Moore

Pitzer Faculty Publications and Research

An ambiguity exists in how psychological scientists use the word “interaction.” This word can refer to physical interactions between components that constitute the mechanisms in complex systems, but it can also refer to statistical interactions revealed by General Linear Statistical Models (e.g., Analyses of Variance). Statistical interactions indicate that the nature of the relationship between two variables depends on a third variable, but the discovery of such interactions does not constitute evidence of physical interactions between components in a system. Studies conducted using traditional behavioral genetics methods sometimes reveal statistical interactions between genes and environments, but the presence or absence …

An Experimental Assessment Of Empathy Compared To Perspective Taking On Minority Group Members In Intergroup Exchanges With Majority Group Members, Rain Marie Carroll

College of Graduate Studies: Theses & Dissertations

This study sought to replicate and extend Vorauer and Quesnel’s (2016) research on the malleability of ingroup status perceptions. With a sample of White majority and Indigenous minority Canadians, Vorauer and Quesnel tested the impact of being the target of two common intergroup relation strategies (i.e., empathy and perspective taking) on perceptions of status in society. They concluded that when minority group members were the targets of empathy rather than perspective taking, the targets experienced a significant decrease in perceptions of ingroup societal status. In the present experiment, White participants were randomly assigned the role of actor or target, and …

The Punitive Effect Of Electric Shock In Rats In Relation To The Rate Of Food Reinforcement, Vincent A. Bello

Capstones and Honors Theses

The purpose of the present experiment was to examine effects of the rate of reinforcement on the punitive function of shock for 4 rats. In baseline conditions, rats’ lever presses were reinforced with food according to a VI schedule. During punishment conditions, a VR-5 schedule of shock punishment was superimposed on the VI schedule. Across pairs of baseline and punishment conditions, the rate of reinforcement ranged from 0.5 to 6 food deliveries per min. Response rates during the baseline and punishment conditions generally increased as the reinforcement rate was raised for two out of four rats. For three rats, suppression …

Delay Discounting And Cannabinoid Enzyme Inhibitors, Devin Andrew Galdieri

Graduate Theses, Dissertations, and Problem Reports (ETD)

Delay discounting is a measure of impulsive choice that is correlated with maladaptive behavior and psychological disorders. Disruptions to serotonin and dopamine pathways can cause changes in delay discounting, as can lesions to the prefrontal cortex and nucleus accumbens. The endocannabinoid system modulates other neurotransmitter systems, including dopamine and serotonin pathways. Cannabinoid receptors type 1 are found in relatively high concentrations in the nucleus accumbens and the prefrontal cortex. These receptors are activated by endogenous cannabinoids, which are synthesized on demand and broken down by catabolic enzymes. The action of these enzymes can be inhibited by a class of drugs …

Exercise As A Therapeutic For Hiv-1-Associated Neurocognitive Deficits, Michael N. Cranston

Theses and Dissertations

Human Immunodeficiency Virus (HIV-1) afflicts nearly 38 million individuals worldwide (Joseph et al., 2013; “WHO | HIV/AIDS,” 2016). Despite the reduction in disease mortality due to increased use of antiretroviral medication, HIV-1 associated neurocognitive disorder (HAND) affects approximately 50% of HIV infected individuals (Antinori et al., 2007; Castellon, Hinkin, Wood, & Yarema, 1998; Castelo, Sherman, Courtney, Melrose, & Stern, 2006; Cysique & Brew, 2009; Heaton et al., 2011, 2015). The brain itself is particularly sensitive to HIV-1 related viral proteins and viral infection (Masliah, DeTeresa, Mallory, & Hansen, 2000), thus, it is vital to empirically examine potentially effective therapeutics which …

Maternal Control, Shame, And Alexithymia, Alyson Pogue

EWU Masters Thesis Collection

There is research to suggest that a girl’s negative relationship with her mother can affect her psychological adjustment as an adult. One example of this negative relationship is a mother who excessively controls her daughter. This type of negative relationship is associated with many psychological difficulties, including alexithymia (i.e. the inability to identify and express what one is feeling) and shame (i.e. pervasive feelings of worthlessness and inadequacy; Kooiman et al., 2004; Kapur & Rai, 2013). A controlling mother can make her child feel like she lacks autonomy (i.e. she lacks a sense that she is capable of accomplishing important …

The Effect Of Religious Dress On Perceived Attractiveness And Trustworthiness, Courtney Swank

College of Graduate Studies: Theses & Dissertations

The hijab, a symbol of modesty and privacy in the Islamic faith, negatively affects ratings of perceived attractiveness. Although postcolonial feminism strives to portray women as not one universal group, but as an incorporation of different races, ethnicities, social classes, and other cultures, the Western world may not be where it endeavors to be. In this study the impact of the hijab on people’s perceptions of attractiveness was examined. Participants rated four target photos of the same woman with and without a hijab, and with or without cosmetics. Attractiveness and trustworthiness was then assessed in each condition, between genders, in …

Advancing Understanding Of Dynamic Mechanisms In Onset To Event Models: Discrete Time Survival Mediation With A Time Variant Mediator, Heather Lasky Mcdaniel

Theses and Dissertations

Integrating discrete time survival and mediation analytic approaches, discretetime survival mediation models (DTSM) help researchers elucidate the impact of predictors on the timing of event occurrence. Though application of this model has been gainful in various applied developmental and intervention research contexts, empirical work has yet to consider how DTSM models operate with a mediator that has a varying effect over time. The importance of examining this situation has important impacts for application of the model, given more complex statistical models are required, and subsequent interpretation of model parameters differ from the basic DTSM model. The overarching purpose of this …

Beauty Is In The Eye Of The Beer Holder: An Initial Investigation Of The Effects Of Alcohol, Attractiveness, Warmth, And Competence On The Objectifying Gaze In Men, Abigail R. Riemer, Michelle Haikalis, Molly R. Franz, Michael Dodd, David Dilillo, Sarah Gervais

Department of Psychology: Faculty Publications

Despite literature revealing the adverse consequences of objectifying gazes for women, little work has empirically examined origins of objectifying gazes by perceivers. Integrating alcohol myopia and objectification theories, we examined the effects of alcohol as well as perceived female attractiveness, warmth, and competence on objectifying gazes. Specifically, male undergraduates (n = 49) from a large U.S. Midwestern university were administered either an alcoholic or placebo beverage. After consumption, participants were asked to focus on the appearance or personality (counterbalanced) of pictured women who were previously rated as high, average, or low in attractiveness, warmth, and competence. Replicating previous work, appearance …

Applying Psychological Theories Of Personality, Identity, And Intergroup Conflict To Radical Violence: A Case Study Of Extremist Behavior, Sydney Flynn

CMC Senior Theses

This paper aims to address possible psychoanalytical explanations for the heinous acts in which terrorists, particularly ISIS, engage. It focuses on Harold D. Lasswell’s principles of the id, ego, and superego as well as Tajfel and Turner’s social identity theory. Within the framework of these two theories, relevant psychological and social psychological theories are discussed in order to explore a possible connection between the psyche of violent perpetrators and their actions. By exploring these connections, I find that there may be more nuanced psychological explanations for these violent acts, which could lead to new methods of weakening perceived biases, intergroup …

Effects Of Learned Exercises On Gross Motor Coordination In Children With Asd, Garrett Myers

CMC Senior Theses

The effectiveness of a teaching progression to teach three “Olympic” exercises and improve gross motor coordination was evaluated with four children (3 boys, 1 girl) diagnosed with autism spectrum disorder (ASD). A multiple baseline design across children and within children across activities was used to evaluate the effectiveness of the teaching progression used to teach the physical exercise program, which consisted of three “Olympic” events (long jump, 50 foot dash, and a relay race). Results showed all four participants learned the three “Olympic” exercises, with all four participants mastering at least one of the three exercises. Two participants mastered all …

Effects Of Delay And Signals On Choice Between Delayed Food Alone And Immediate Food With Delayed Shock, Forrest James Toegel

Graduate Theses, Dissertations, and Problem Reports (ETD)

Much of the research in the area of self-control has examined choice between small immediate reinforcers and large delayed reinforcers, but many problems result from situations in which a single choice produces consequences of conflicting valence: Those in which the immediate outcome is reinforcing and the delayed outcome is aversive. Recent research has evaluated how preference for a large reinforcer which is followed by a delayed shock changes as a function of the delay to shock and how the intensity and duration of delayed shock affects the value of a large reinforcer. The present set of experiments investigated how the …

Effects Of Reinforcement Rate On The Aversive Function Of Timeout From Positive Reinforcement, Cory Whirtley

Graduate Theses, Dissertations, and Problem Reports (ETD)

Although the use of timeout from positive reinforcement is widespread and has been shown to be an effective punisher in clinical settings, the factors responsible for its effectiveness are not fully understood. The present experiment was designed to evaluate one of these factors, the reinforcement rate underway during periods of time-in. Rats’ lever pressing was maintained on variable-interval schedules of food reinforcement in a multiple schedule with two components. In one component, no timeouts were delivered. In the other component, when a variable-ratio schedule was met, lever presses were followed by a 30-s timeout during which a tone sounded, the …

Confidence In Academic Testing: The Effect Of Induced Checking And Anxiety On University Students' Emotional Responses To, And Performance In, Academic Challenge, Elijah Bruner

All Master's Theses

Academic tests such as the American College Testing (ACT), Scholastic Aptitude Test (SAT), and National Assessment for Educational Progress (NAEP) have been used to assess academic aptitude. Research suggests that both test anxiety and test emotions (positive and negative) influence academic performance. The purpose of this study was to investigate the effects of test anxiety and uncertainty (i.e., re-checking items) on performance and test emotions. It was hypothesized that induced checking and participant anxiety would negatively predict performance and positive testing emotions, and positively predict negative testing emotions. It was also hypothesized that induced checking and anxiety would interact, with …

Transient Signals And Inattentional Blindness In A Multi-Object Tracking Task, Dakota B. Palmer, Yusuke Yamani, Taylor L. Bobrow, Nicole D. Karpinsky, Dean J. Krusienski

Psychology Faculty Publications

Inattentional blindness is a failure to notice an unexpected event when attention is directed elsewhere. The current study examined participants' awareness of an unexpected object that maintained luminance contrast, switched the luminance once, or repetitively flashed. One hundred twenty participants performed a dynamic tracking task on a computer monitor for which they were instructed to count the number of movement deflections of an attended set of objects while ignoring other objects. On the critical trial, an unexpected cross that did not change its luminance (control condition), switched its luminance once (switch condition), or repetitively flashed (flash condition) traveled across the …

Is Pecking Aversive To A Pigeon Or Is It Only The Delay To Reinforcement?, Danielle M. Andrews

Theses and Dissertations--Psychology

The principle of least effort suggests that animals should minimize effort to reinforcement. Thus, not pecking should be preferred over pecking. However, pigeons often peck when it is allowed but not required (e.g., fixed time schedules) but pecking may be adventitiously reinforced. In the present experiment, to better compare a schedule of reinforcement that requires pecking with one that requires the absence of pecking, we compared a fixed-interval (FI) schedule in which reinforcement follows the first peck after the interval has elapsed and a differential-reinforcement-of-other behavior (DRO) schedule which requires pigeons abstain from pecking for a similar interval. The delay …

The Self-Reported And Behavioral Effects Of Propylene Glycol And Vegetable Glycerin In Electronic Cigarette Liquids, Arit M. Harvanko

Theses and Dissertations--Psychology

Little is known about how electronic cigarette (EC) users manipulate device parameters, what factors drive their use, and how non-nicotine ingredients influence the stimulus effects of EC aerosols. The ingredients propylene glycol (PG) or vegetable glycerin (VG) serve as the base for virtually all electronic cigarette liquids, and information on how they affect the using experience would provide important groundwork for the study of other ingredients. In this dissertation, results from a survey and laboratory study focused on the stimulus effects of ECs, and the influence of PG and VG, will be discussed. A total of 522 regular EC users …

Alcohol-Induced Impairment Of Simulated Driving Performance And Behavioral Impulsivity In Dui Offenders, Nicholas A. Van Dyke

Theses and Dissertations--Psychology

Licensed drivers arrested for driving under the influence (DUI) of alcohol have increased rates of vehicle crashes, moving violations, traffic tickets, and contribute to an estimated 120 million occurrences of impaired driving per year (Evans, 2004; Jewett et al., 2015). Survey research on DUI offenders indicates traits of impulsivity (e.g., sensation seeking). Together, these pieces of evidence suggest that DUI offenders display patterns of impulsive action and risk-taking while driving. However, to-date DUI offenders are rarely studied in a laboratory setting, and not much is known about how they respond to a dose of alcohol. The present study examined the …

Effects Of Social Interaction On Morphine Conditioned Place Preference In Adolescent Male Rats, Virginia G. Weiss

Theses and Dissertations--Psychology

The fact that adolescents commonly initiate drug use in social settings is well established. Both clinical and preclinical research has investigated how social interaction is altered by a variety of drugs of abuse. What is less understood is how the rewarding value of drugs of abuse is affected by the presence of social peers. This dissertation aimed to investigate the interaction of morphine and social play on conditioned place preference (CPP) in adolescent male Sprague Dawley rats, using both behavioral and immunohistochemistry (IHC) methods. Rats were exposed to morphine (0, 1, or 3 mg/kg; s.c.), social interaction, or a combination …

Questioning The Modality Of The Occipital Lobe, William J. Brixius

Theses and Dissertations

This dissertation explores the occipital lobe’s response to non-visual inputs, and whether this responsivity partitions into separate localization and identification pathways as seen with visual inputs. We hypothesized that occipital areas may merely prefer visual inputs, while maintaining similar task-based sensory recruitment in response to other senses. Our secondary hypothesis was that the robust occipital activation seen in late-blind participants stems at least initially from standard connections present even in the typically sighted, and that these standard connections are functionally utilized by the typically sighted in spatially relevant non-visual analyses. Our initial literature review supported our hypotheses that the occipital …

Evaluative Conditioning Of Product Preferences: An Eye-Tracking Perspective, Christine E. Weber

Theses and Dissertations

In evaluative conditioning, the affective response toward a neutral stimulus is altered by pairing it with a positive or negative stimulus. One behavioral and two eye tracking studies were conducted to investigate how evaluative conditioning operates on consumer preferences by pairing neutral products with valenced music and using multiple product exemplars and test trials in order to test evaluative effects at the individual level. Study 1 showed an overall positive effect of evaluative conditioning on choice and liking ratings, although there were individual differences in the magnitude and direction of the effect. Study 2 found significant results at the individual …

Neurochemistry, Physiology, And Behavior In A Model Of Gulf War Illness, Victoria A. Macht

Theses and Dissertations

Upon returning from the first Gulf War, soldiers cited a plethora of unexplained physical and cognitive deficits which have since been termed Gulf War Illness (GWI). Presentation of GWI is positively correlated with pyridostigmine bromide (PB) use, which was prophylactically administered to soldiers in response to threats of chemical warfare. To test the overarching hypothesis that PB interacted with stress of deployment to alter neural, endocrine, and immune systems, the following studies used a 2×2 rodent model with 14 days of drug treatment (vehicle; PB) and 10 days of repeated restraint stress (stressed) or non-stressed-control conditions. Results indicate that PB …

The Effects Of Automation Transparency And Ethical Outcomes On User Trust And Blame Towards Fully Autonomous Vehicles, Nathan Andrew Hatfield

Psychology Theses & Dissertations

The current study examined the effect of automation transparency on user trust and blame during forced moral outcomes. Participants read through moral scenarios in which an autonomous vehicle did or did not convey information about its decision prior to making a utilitarian or non-utilitarian decision. Participants also provided moral acceptance ratings for autonomous vehicles and humans when making identical moral decisions.

It was expected that trust would be highest for utilitarian outcomes and blame would be highest for non-utilitarian outcomes. When the vehicle provided information about its decision, trust and blame were expected to increase. Results showed that moral outcome …

Investigating The Roles Of Mechanoreceptive Channels In Tactile Apparent Motion Perception: A Vibrotactile Study, Phill Kim, Philip Servos Dr.

Theses and Dissertations (Comprehensive)

Tactile apparent motion (TAM) is a perceptual phenomenon in which consecutive presentation of multiple tactile stimuli creates an illusion of motion. Employing a novel tactile display device, the Latero, allowed us to investigate this. The current study focused on the Rapidly Adapting (RA) channel and Slowly Adapting I (SAI) channel on the index finger. The experiment implemented vibrotactile masking stimuli to target the mechanoreceptive channels with the goal of gaining better insight into the involvement of mechanoreceptive channels in the perception of TAM. Masking stimuli were used because previous studies have used them to differentiate between different channels; a …

Attrition In Behavioral Parent Training Programs In Clinical And Community Settings: A Meta-Analytic Review, Brett C. Michael

UNF Graduate Theses and Dissertations

Abstract

It is estimated that approximately 16-20% of youth will develop a diagnosable behavior disorder. Behavioral parent training is a valuable approach to address disruptive behaviors by teaching parents how to effectively manage their child’s challenging behavior with non-physical disciplinary techniques. While these programs are generally effective, attrition rates have been found to be as high as 60% in some cases. This review provides information about the characteristics commonly associated with these programs, the attrition rates of each program, and the general effectiveness of the programs. Meta-analytic procedures were implemented to identify contributing factors leading to withdrawal from intervention.

Treatment Analysis Of A Captive Male Jaguar (Panthera Onca), Megan Colleen Morris

UNF Graduate Theses and Dissertations

Large carnivores in human care have been reported to engage in stereotypic behaviors. Such behavior is thought to be correlated with high stress levels, in part, due to captive environments limiting opportunities for functional consequences and environmental stimuli. Moreover, there are several arguments stating that stereotypic behaviors can be indicative of poor welfare, as they can often have severe negative emotional and physical effects on the animal. The first portion of this study included a five-phase treatment analysis which evaluated whether environmental manipulations decrease the frequency of stereotypic behaviors including pacing, over-grooming and tail-sucking exhibited by a single male jaguar …
