How Perception Meets Hermeneutics: An Empirical Investigation Of Tasseography, Elizabeth Avetisian Jan 2022

How Perception Meets Hermeneutics: An Empirical Investigation Of Tasseography, Elizabeth Avetisian

International Journal of Transpersonal Studies Advance Publication Archive

Tasseography is a divination method to provide insight about the seeker’s past, present, or future life by interpreting patterns in the dregs of a liquid. Although it has been practiced with coffee throughout Europe and Middle East, particularly among women, no known studies exist on the seer’s perceptual process of the ambiguous patterns or how the roles of the seeker and seer, symbols, ritual, and cultural epistemology shape the divinatory hermeneutics. This study focused on the Armenian coffee divination ritual, asking what are the processes and conditions that enable experienced cup readers to obtain divinatory insight in tasseography? Two seekers …


Emotion And Judgment In Young Women Of A Society In Transition, Maura A. E. Pilotti, Khadija El Alaoui Jan 2022

Emotion And Judgment In Young Women Of A Society In Transition, Maura A. E. Pilotti, Khadija El Alaoui

International Journal of Transpersonal Studies

The present study asked whether emotional responses to narratives of moral transgressions are shaped by the reader’s assumed relationship with the injured party (i.e., oneself, familiar other, and unfamiliar other). Its goal was to test a cultural, religious, and individualistic account of such responses in young females of a traditional society in transition towards a sustainable integration into the global economy. To this end, female college students from the Kingdom of Saudi Arabia were asked to identify their emotional reaction to each of several moral transgressions, report its intensity and then judge the severity of the transgression. In agreement with …

The Role Of Spiritual Intelligence And Differentiation In Predicting Marital Adjustment Of Married Iranian Students, Sedigheh Ahmadi, Richard H. Morley, Faezeh Ghalebi, Hossein Ilanloo, Christine D. Nguyen Jan 2022

The Role Of Spiritual Intelligence And Differentiation In Predicting Marital Adjustment Of Married Iranian Students, Sedigheh Ahmadi, Richard H. Morley, Faezeh Ghalebi, Hossein Ilanloo, Christine D. Nguyen

International Journal of Transpersonal Studies

The aim of this study was to investigate the role of spiritual intelligence and differentiation in predicting marital adjustment of Iranian students. The participants of this study were 312 married students from Yazd University. The instruments used in this study were the Dyadic Adjustment Scale (DAS) to measure marital adjustment, Differentiation of Self- Inventory, and the Spiritual Intelligence Self-Report Inventory (SISRI). The results of the study demonstrated that spiritual intelligence predicted the marital adjustment of married students (p


The Program To Reduce Implicit Bias In Carroll Hospital Center Using The Implicit Association Test, Katherine E. Traynor Jan 2022

The Program To Reduce Implicit Bias In Carroll Hospital Center Using The Implicit Association Test, Katherine E. Traynor

Capstone Showcase

Natural brain processes make all individuals susceptible to unconscious bias; however, stressful, fearful, or anger-evoking situations as well as the negative influence of media and social surroundings increase the risk of holding obstructive bias, and there is a greater risk of being negatively impacted by this phenomenon when belonging to a minority population (Rose & Flores, 2020). As a result, high rates of infant mortality (10.2 deaths per 1,000 live births for the Non-Hispanic Black population compared to 4.1 in the White population) and cardiovascular related diseases (190.0 cases per 1,000 in the Non-Hispanic Black population compared to 161.3 in …

Dataset: Knowledge And Attitude Retention Following An Implicit Bias Classroom Workshop, Yuanyuan Zhou, Joel Purkiss, Malvika Juneja, Jocelyn Greely, Anitra Beasley, Anne Gill

Faculty, Staff and Students Publications

Background: Baylor College of Medicine provides a classroom-based implicit bias workshop to all third-year medical students to increase students’ awareness of their unconscious bias and develop strategies for reducing health care disparities. The workshop meets our immediate goals and objectives. However, we are unsure if the benefit would be long-term or diminish over time.

Methods: To examine the concept retention from the implicit bias classroom workshop, we administered a self-developed seven-item seven-point Likert-scale survey to our medical students at pre-, post-, and one-year post-workshop attendance.

Results: The data set was comprised of survey results from two cohorts of our third …


Filled/Non-Filled Pairs: An Empirical Challenge To The Integrated Information Theory Of Consciousness, Amber R. Hopkins, Kelvin J. Mcqueen Dec 2021

Filled/Non-Filled Pairs: An Empirical Challenge To The Integrated Information Theory Of Consciousness, Amber R. Hopkins, Kelvin J. Mcqueen

Philosophy Faculty Articles and Research

Perceptual filling-in for vision is the insertion of visual properties (e.g., color, contour, luminance, or motion) into one’s visual field, when those properties have no corresponding retinal input. This paper introduces and provides preliminary empirical support for filled/non-filled pairs, pairs of images that appear identical, yet differ by amount of filling-in. It is argued that such image pairs are important to the experimental testing of theories of consciousness. We review recent experimental research and conclude that filling-in involves brain activity with relatively high integrated information (Φ) compared to veridical visual perceptions. We then present filled/non-filled pairs as …


The Moderating Role Of Social Support In Stigma And Symptoms Of Anxiety And Depression, Taylor Phillips Aug 2021

The Moderating Role Of Social Support In Stigma And Symptoms Of Anxiety And Depression, Taylor Phillips

Undergraduate Honors Theses

In this study, we examine the relationship between having a support system and the stigma individuals face with depression and anxiety symptoms. The aim of this study was to examine if having a support system acts as a buffer between perceived stigma and mental health symptoms. For this study, I conducted an online survey to measure symptoms of depression and anxiety, experiences with both perceived and internalized stigma, and social support. While 93 total participants engaged in the survey, only 52 fully completed the survey and passed two attention-check questions to ensure no invalid participation (e.g., BOTS) were present. In …


Negative Urgency's Influence On State-Level, Emotion-Based Changes In Alcohol-Related Cognitions, Noah Wolkowicz Jul 2021

Negative Urgency's Influence On State-Level, Emotion-Based Changes In Alcohol-Related Cognitions, Noah Wolkowicz

Graduate Theses and Dissertations

This project expanded on the Acquired Preparedness Model of Risk (APMR) by examining how Negative Urgency (NU), the tendency to act rashly in negative emotional states, affects emotion-based changes in alcohol cognitions to produce risk for alcohol use. The APMR prioritizes the role of outcome expectancies as the means through which traits such as NU, convey alcohol use risk. However, this model treats these cognitions as static and often fails to assess their valence; further, alcohol-cognitions fluctuate in response to negative emotions and may become more salient during these states. Therefore, this study examined: 1) how NU impacts negative emotion-based, …


Where To Draw The Line: Evaluating Visuospatial And Attentional Processing In Individuals With Autism Spectrum Disorders, Alisha Steigerwald Jun 2021

Where To Draw The Line: Evaluating Visuospatial And Attentional Processing In Individuals With Autism Spectrum Disorders, Alisha Steigerwald

University Honors Theses

Objective: We investigated visuospatial processing in individuals with autism using bisection and quadrisection tasks to evaluate the presence of a possible downward vertical spatial bias that could provide insights into the preference for attending to the mouth in ASD populations.

Methods: Twenty participants with ASD and 20 age, IQ, and sex-matched control participants were recruited (ages 6-23). Participants were asked to bisect, quadrisect from the top, and quadrisect from the bottom vertical lines placed in their left, center, and right visual spaces. Distance from the true midpoint and quadripoint were calculated and compared between the two groups.

Results: No significant …


Exploring Tactile Art-Making With Deafblind Students And Their Families: An Opportunity For Creative Play, Alice Rodgers May 2021

Exploring Tactile Art-Making With Deafblind Students And Their Families: An Opportunity For Creative Play, Alice Rodgers

Expressive Therapies Capstone Theses

The impact of a deafblind diagnosis on an individual’s mental health and the well-being of the family involved can be profound. However, current research and available literature for the mental health treatment and therapy practices of deafblind persons and their families is limited (Kyzar et al., 2016; “WFDB Global Report 2018,” n.d.). This thesis used the Leeds Family Psychology and Therapy Service principles (Leeds FPTS) and the Expressive Therapies Continuum with established deafblind teaching strategies to facilitate an original arts-based community project entitled: “Things We Like.” This project provided an opportunity for deafblind students (ages three to 22) and their …

Assessing Rat Behavioral Response To Novelty, Neha Mathew Apr 2021

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 …


Aberrant Maturation Of The Uncinate Fasciculus Follows Exposure To Unpredictable Patterns Of Maternal Signals, Steven J. Granger, Laura M. Glynn, Curt A. Sandman, Steven L. Small, Andre Obenaus, David B. Keator, Tallie Z. Baram, Hal S. Stern, Michael A. Yassa, Elyssia Poggi Davis Feb 2021

Aberrant Maturation Of The Uncinate Fasciculus Follows Exposure To Unpredictable Patterns Of Maternal Signals, Steven J. Granger, Laura M. Glynn, Curt A. Sandman, Steven L. Small, Andre Obenaus, David B. Keator, Tallie Z. Baram, Hal S. Stern, Michael A. Yassa, Elyssia Poggi Davis

Psychology Faculty Articles and Research

Across species, unpredictable patterns of maternal behavior are emerging as novel predictors of aberrant cognitive and emotional outcomes later in life. In animal models, exposure to unpredictable patterns of maternal behavior alters brain circuit maturation and cognitive and emotional outcomes. However, whether exposure to such signals in humans alters the development of brain pathways is unknown. In mother–child dyads, we tested the hypothesis that exposure to more unpredictable maternal signals in infancy is associated with aberrant maturation of corticolimbic pathways. We focused on the uncinate fasciculus, the primary fiber bundle connecting the amygdala to the orbitofrontal cortex and a key …

Communication Disorders & Special Education Faculty Publications

Video social stories are used to facilitate understanding of social situations for adolescents with autism spectrum disorder (ASD). This study explored the use of eye tracking technology to understand how adolescents with and without ASD visually attend to video social story content and whether visual attention is related to content comprehension. Six adolescents, with and without ASD, viewed a video social story of visiting a dental office. Eye gaze metrics, including fixation duration and count, and visit duration were collected to measure visual attention, and a knowledge assessment was administered for comprehension. Results indicated adolescents with ASD fixated and maintained …


Difficult Turned Easy: Suggestion Renders A Challenging Visual Task Simple, Mathieu Landry, Jason Da Silva Castanheira, Jérôme Sackur, Amir Raz Dec 2020

Difficult Turned Easy: Suggestion Renders A Challenging Visual Task Simple, Mathieu Landry, Jason Da Silva Castanheira, Jérôme Sackur, Amir Raz

Psychology Faculty Articles and Research

Suggestions can cause some individuals to miss or disregard existing visual stimuli, but can they infuse sensory input with nonexistent information? Although several prominent theories of hypnotic suggestion propose that mental imagery can change our perceptual experience, data to support this stance remain sparse. The present study addressed this lacuna, showing how suggesting the presence of physically absent, yet critical, visual information transforms an otherwise difficult task into an easy one. Here, we show how adult participants who are highly susceptible to hypnotic suggestion successfully hallucinated visual occluders on top of moving objects. Our findings support the idea that, at …


Historical Trauma Response Scores As A Function Of Unresolved Grief And Substance Use Disorder In American Indian Populations, Andrew R. Saunders Nov 2020

Historical Trauma Response Scores As A Function Of Unresolved Grief And Substance Use Disorder In American Indian Populations, Andrew R. Saunders

Undergraduate Research Symposium

Abstract

Researchers are interested in the outcomes of interventions, specifically, measuring historical trauma (HT) among American Indian/Alaska Native communities and the long-term distress and substance abuse as a result of historical trauma response (HTR). Previous literature has implicated limitations in the clinical conceptualization of the relationship between intergenerational transfer of HTR and substance abuse. The aim of the current study is to examine treatment efficacy of 50 homosexual, American Indian males randomized to a culturally-adapted juxtaposition of (1) Group Interpersonal Psychotherapy (IPT), (2) Cognitive Processing Therapy (CPT), and (3) Historical Trauma and Unresolved Grief Intervention (HTUG), or (4) waitlisted on …


Empowering Nurses Of Minority In The Face Of Incivility And Bullying: Through The Lens Of Phenomenology, Corrine Floyd Oct 2020

Empowering Nurses Of Minority In The Face Of Incivility And Bullying: Through The Lens Of Phenomenology, Corrine Floyd

Dissertations

Abstract

Up to 85% of nurses have reported exposure to incivility in the workplace (Hunt & Marini, 2012). The often-subtle nature of incivility toward nurses in a minority population may partially explain why it remains a problem. Healthcare organizations realize the need for civility to counter the high turnover rate, staff shortages, and low job satisfaction reported by nurses, but lack understanding of how nurses of a minority population perceive incivility and bullying. This study aimed to answer the research question how do nurses with minority representation experience incivility and bullying versus empowerment in the workplace? A descriptive phenomenological design …


Clusters Of Individuals Experiences Form A Continuum Of Persistent Non-Symbolic Experiences In Adults, Jeffery A. Martin Aug 2020

Clusters Of Individuals Experiences Form A Continuum Of Persistent Non-Symbolic Experiences In Adults, Jeffery A. Martin

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

Persistent forms of nondual awareness, enlightenment, mystical experience, and so forth (Persistent Non-Symbolic Experience) have been reported since antiquity. Though sporadic research has been performed on these experiences, the scientific literature has yet to report a large-scale cognitive psychology study of this population. Method: Assessment of the subjective experience of 319 adult participants reporting persistent non-symbolic experience was undertaken using 6-12 hour semi-structured interviews and evaluated using grounded theory and thematic analysis. Results: Five core, consistent categories of change were uncovered: sense-of-self, cognition, affect, perception, and memory. Participants’ reports formed phenomenological groups in which the types of change …


Rejection Sensitivity And Social Support As Predictors Of Peer Victimization Among Youth With Psychiatric Illness, Katherine C. Hyde Jul 2020

Rejection Sensitivity And Social Support As Predictors Of Peer Victimization Among Youth With Psychiatric Illness, Katherine C. Hyde

Graduate Theses and Dissertations

In this study, I examined whether rejection sensitivity and perceptions of social support predicted concurrent peer victimization in a sample of adolescents with psychiatric illness. Participants included 43 adolescents, aged 12-18 with diverse psychiatric diagnoses, who were recruited from a summer residential treatment program. Participants completed measures of peer victimization, perceptions of social support, and rejection sensitivity. Participants also completed the global victimization item in the Revised Olweus Bully/Victim Questionnaire, which allowed for comparison of rates of peer victimization across studies (Solberg & Olweus, 2003). Results replicate and extend previous research that indicates adolescents with psychiatric illness experience high rates …


Scope Of Attention Variation As A Function Of Anxiety And Depression, Kathleen Anne O'Donnell Jun 2020

Scope Of Attention Variation As A Function Of Anxiety And Depression, Kathleen Anne O'Donnell

Electronic Theses, Projects, and Dissertations

As a social species, correct emotional perception is so vital, that the human brain has evolved a mechanism to control attentional choices by exerting a narrowed field of perception during danger, called the scope of attention (SoA). The SoA determines what information will be focused on or ignored by blocking the perception of non-relevant items and increasing selective focus on danger; even if danger is merely a sad-face. The emotional items blocked from perception cannot be remembered because they were never perceived. But, attention-control to emotional stimuli also varies with mood, as seen in mood-disorders. A mood-disorder’s effect upon the …


Moving Through Depression: Development Of A Dance/Movement Therapy Method In Psychiatric Inpatient Care, Melissa Olmedo May 2020

Moving Through Depression: Development Of A Dance/Movement Therapy Method In Psychiatric Inpatient Care, Melissa Olmedo

Expressive Therapies Capstone Theses

Short-term psychiatric hospitalization is a challenging health care model due to its short duration of care, treating the highest risk psychiatric population. Priority care within a short-term psychiatric hospitalization involves monitoring a patient’s safety for stabilization by decreasing acute mental health symptoms. Holistic psychotherapy treatment options are needed to meet the severity of patients’ symptoms for effective stabilization within a short-term model of care. This paper investigates the first implementation of a dance/movement therapy (DMT) method within two short-term units in a notable Boston hospital. The DMT group called Mindful Movement was facilitated weekly as single sessions to adults ranging …


Rhythm And Safety Of Social Engagement: Polyvagal Theory Informed Dance/Movement Therapy, Suzanne Weare May 2020

Rhythm And Safety Of Social Engagement: Polyvagal Theory Informed Dance/Movement Therapy, Suzanne Weare

Expressive Therapies Capstone Theses

The polyvagal theory has exerted great influence on the field of clinical therapy since the 1990s by proposing an understanding of the psychological expression seen in clients as a reflection of their physiological state of safety or threat of danger. When affect and psychological states are viewed through the lens of the autonomic nervous system directed by neuroception through bidirectional vagal nerve information, therapeutic presence and somatic therapy practices, such as those utilized in the field of dance/movement therapy, become more conceivable as best practices to treat a variety of psychological conditions to include trauma recovery, autism spectrum disorders, and …


Mental Associations And Music Therapy: Including The History Of Associationism And The Neurology Of Associations, Dianna Rose May 2020

Mental Associations And Music Therapy: Including The History Of Associationism And The Neurology Of Associations, Dianna Rose

Expressive Therapies Capstone Theses

Associations are formed in our minds based upon three elements: sensory experience, emotions, and memories. These associations, unique to each individual, dictate thoughts, beliefs, behaviors, and actions. Some are necessary and supportive, while others can be maladaptive. Established associations can be changed, and new associations can be formed, to align with a client’s goals. The literature presents a strong history of associationism, as well as a body of research that demonstrates the neurological processes of how mental associations are formed. There are also studies showing how music activates the brain. However, there is a lack of research which draws direct …


An Experimental Test Of The Effects Of Sleep Deprivation On Approach Behavior, Rebecca L. Campbell May 2020

An Experimental Test Of The Effects Of Sleep Deprivation On Approach Behavior, Rebecca L. Campbell

Graduate Theses and Dissertations

Emotion regulation and sleep have been identified as mechanisms that may be involved in the development and maintenance of many mental health disorders. However, there has been little research into the relation between sleep and emotion regulation. To address this gap in knowledge, a novel study was conducted. We hypothesized that sleep deprived individuals would demonstrate less approach behavior toward a negatively valenced stimulus, as well as increased self-reported avoidance, compared to a control group. To test this, a randomized controlled experiment using a behavioral measure of approach and a self-report measure of avoidance was conducted. Fifty-two healthy individuals ages …


Searching For Neural Mechanisms Of Social Cognition, Chandler Siemonsma, Cristina Uribe, Louanne Boyd, Aaron Schurger, Deanna Hughes, Tian Lan May 2020

Searching For Neural Mechanisms Of Social Cognition, Chandler Siemonsma, Cristina Uribe, Louanne Boyd, Aaron Schurger, Deanna Hughes, Tian Lan

Student Scholar Symposium Abstracts and Posters

Social cognition involves the integration and pruning of perceptual information which leads to the formation of an abstract representation, which is also known as the perceptual gist. This study examined 87 differences in visual perception of Mooney face stimuli of differing sizes and the relationship to gist formation in ten individuals with autism compared to neurotypical controls. Parents of both groups completed the Social Responsiveness Scale (SRS-2) to assess social functioning in real-world scenarios.

The Project Talent Twin And Sibling Study: Zygosity And New Data Collection, Carol A. Prescott, Ellen E. Walters, Thalida Em Arpawong, Catalina Zavala, Tara L. Gruenewald, Margaret Gatz

Psychology Faculty Articles and Research

The Project Talent Twin and Sibling (PTTS) study includes 4481 multiples and their 522 nontwin siblings from 2233 families. The sample was drawn from Project Talent, a U.S. national longitudinal study of 377,000 individuals born 1942–1946, first assessed in 1960 and representative of U.S. students in secondary school (Grades 9–12). In addition to the twins and triplets, the 1960 dataset includes 84,000 siblings from 40,000 other families. This design is both genetically informative and unique in facilitating separation of the ‘common’ environment into three sources of variation: shared by all siblings within a family, specific to twin-pairs, and associated with …


Mood Effects And Individual Differences On Reappraisal And Distraction: An Erp Study Of The Sensitivity Of Emotion Regulation Strategies, Elsa Mastico Jan 2020

Mood Effects And Individual Differences On Reappraisal And Distraction: An Erp Study Of The Sensitivity Of Emotion Regulation Strategies, Elsa Mastico

All Master's Theses

The present research evaluated the effect of mood and individual differences on the regulatory process of emotions by using a regulation task with negative and neutral images to assess reappraisal and distraction ability. Specifically, this research evaluated the average amplitude of the latent positive potential (latent positivity, LPP) brainwave linked to distraction and reappraisal using an ERP analysis. In addition, the current study compared the modulation of the LPP to the self-reported mood of the participants and their individual differences in regulation ability through scores of a self-report emotion regulation questionnaire. The latent positive potentials from an emotion regulation task …


Retrieval-Induced Forgetting In Autism Spectrum: Combining Narrative Experience With Clinical Research To Explore Stress-Induced, Transitory Retrograde Amnesia, Elizabeth Willsmore-Finkle Jan 2020

Retrieval-Induced Forgetting In Autism Spectrum: Combining Narrative Experience With Clinical Research To Explore Stress-Induced, Transitory Retrograde Amnesia, Elizabeth Willsmore-Finkle

Scripps Senior Theses

Currently, psychological research explores autism, a blanket term for a range of neurobiological and developmental differences, through a clinical, as opposed to an experiential, lens. Autism has only existed as formal diagnosis under that name since 1943 (Kanner); however, the advocacy of activists such as Temple Grandin, a slaughterhouse systems designer best known for documenting her life with autism in a series of autobiographic accounts, has begun to legitimize the incorporation of emic experiences of autism within clinical research. Researcher Dermot Bowler and colleagues (2011) have conducted extensive reviews of memory distinctions in autism, finding differences of varying degrees across …


Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref Jan 2020

Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref

Dissertations and Theses

In dynamic environments, split-second sensorimotor decisions must be prioritized according to potential payoffs to maximize overall rewards. The impact of relative value on deliberative perceptual judgments has been examined extensively, but relatively little is known about value-biasing mechanisms in the common situation where physical evidence is strong but the time to act is severely limited. This research examines the behavioral and electrophysiological indices of how value biases split-second perceptual decisions and the possible mechanisms underlying the process. In prominent decision models, a noisy but statistically stationary representation of sensory evidence is integrated over time to an action-triggering bound, and value-biases …
