Life Before Birth: A Thematic Analysis Of Memories Of Coming Into Life Part 2: Recollections Of Fetal Life And Birth, Jenny Wade Jan 2022

Life Before Birth: A Thematic Analysis Of Memories Of Coming Into Life Part 2: Recollections Of Fetal Life And Birth, Jenny Wade

International Journal of Transpersonal Studies Advance Publication Archive

This article examines a second set of data produced in a thematic analysis of 68 “earliest memory” narratives submitted to an independent website to explore the question: what do people who claim to remember how they came into the world say about their experience prior to and including birth? Part 1 examined the first and largest subset of the data, narratives of an otherworldly existence consistent with Western reincarnation intermission stage 2 experiences, near-death experience accounts and mythic traditions. This article thematically analyzes descriptions of life in the womb, birth, and apparently veridical out-of-body and other paranormal impressions of events …

The results of the study demonstrated that spiritual intelligence predicted the marital adjustment of married students (p


Unexpected Side Effects: A Cautionary Note On Challenges Of Persistent Self-Transcendence, Elizabeth D. Stephens, Harris L. Friedman Jan 2022

Unexpected Side Effects: A Cautionary Note On Challenges Of Persistent Self-Transcendence, Elizabeth D. Stephens, Harris L. Friedman

International Journal of Transpersonal Studies Advance Publication Archive

Self-transcendence is an ambiguous construct without consensual meaning, yet many claim that it relates to, or even causes, beneficial outcomes. Few discuss its potential deleterious side effects, choosing to focus primarily on positive effects. However, anything with sufficient potency to heal may have unintended side effects, especially when it leads beyond a transitory state to becoming an enduring trait, such as when self-transcendence (ST) becomes persistent self-transcendence (PST). With PST, evidence is overviewed here, along with two illustrative case reports, that people can suffer emotional difficulties, motivation changes, loss of self-reflexivity, anhedonia, dissociation, depersonalization, memory problems, and other psychological concerns. …


Life Before Birth: A Thematic Analysis Of Memories Of Coming Into Life Part 1: Recollections Of Another Realm, Jenny Wade Jan 2022

Life Before Birth: A Thematic Analysis Of Memories Of Coming Into Life Part 1: Recollections Of Another Realm, Jenny Wade

International Journal of Transpersonal Studies Advance Publication Archive

Autobiographic memories prior to birth remain controversial in psychology because such memories are traditionally believed to begin much later when some sense of self is formed. Prenatal sentience, including fetal learning, occurs in species from arthropods to humans, and evidence for autobiographic memories from pre- and neo-natal humans has typically come from clinical case histories of altered-state regression techniques eliciting records from adults or clinical case histories of children in normal states. This thematic analysis examined 68 “earliest memory” narratives submitted to an independent website to explore the question: what do people who claim to remember how they came into …


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 …


Inspiration On Social Media: Applying An Entertainment Perspective To Longitudinally Explore Mental Health And Well-Being, Sophie Janicke-Bowles, Arthur A. Raney, Mary Beth Oliver, Katherine R. Dale, Danyang Zhao, Dominik Neumann, Russell B. Clayton, Alysia A. Hendry Jan 2022

Inspiration On Social Media: Applying An Entertainment Perspective To Longitudinally Explore Mental Health And Well-Being, Sophie Janicke-Bowles, Arthur A. Raney, Mary Beth Oliver, Katherine R. Dale, Danyang Zhao, Dominik Neumann, Russell B. Clayton, Alysia A. Hendry

Communication Faculty Articles and Research

The conditions under which social media use impacts well-being and mental health are complex. The current 10-day longitudinal quasi-experiment (student sample, N = 111) applied an entertainment theory lens to explore the effects of active posting and engaging with hedonic or inspiring Facebook content (vs. passive browsing) on young people’s eudaimonic well-being (levels of connectedness to humanity, love, compassion, presence of meaning) and mental health (anxiety and depressive symptoms). The results provide tentative evidence that finding and sharing inspiring content to a Facebook group increased love and compassion toward others over time. It also led to more compassion at the …


Indicators Of Deception: Science Or Non-Science, Kristina Vasquez Jan 2022

Indicators Of Deception: Science Or Non-Science, Kristina Vasquez

Undergraduate Honors Theses

Deception detection is used by many law enforcement professionals who work in interviews and interrogations. The ability to detect deception or having knowledge on the signs of deception is very important in not only law enforcement, but in other careers and everyday life. The question remains: is deception detection a science or not a science? There are three areas where someone can learn how to detect deception and those are verbal communication, non-verbal communication, and paralanguage. The use of verbal communication looks at what the person is saying with their words. The use of non-verbal communication looks at what someone …


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 …


What Is Transpersonal Psychology? A Concise Definition Based On 20 Years Of Research, Glenn Hartelius Jan 2022

What Is Transpersonal Psychology? A Concise Definition Based On 20 Years Of Research, Glenn Hartelius

International Journal of Transpersonal Studies

Research on definitions of the field of psychology and themes in the literature of the field over a period of 20 years inform this description: Transpersonal psychology is a transformative psychology of the whole person embedded within a diverse, interconnected, and evolving world that pays particular attention to states of consciousness and developmental models reflecting expansion beyond conventional notions of self. Each element of this definition is examined, as well as the four phases of definitional development within the field from its founding in 1968 up to the present.


The Perceived Impact Of Holotropic Breathwork: An Interpretive Phenomenological Analysis, Felipe Landaeta Farizo Jan 2022

The Perceived Impact Of Holotropic Breathwork: An Interpretive Phenomenological Analysis, Felipe Landaeta Farizo

International Journal of Transpersonal Studies

Holotropic Breathwork (HB) is a method of self-exploration developed by Stanislav and Christina Grof. Research has only just begun to investigate the effects of HB, while the possible influence of the context and other features of HB within the experience and its impact have not been studied in depth. This qualitative study investigated the perceived impact of HB on 6 women and 6 men (ages 25-67) in Chile, using Interpretive Phenomenological Analysis (IPA), an emergent method developed specifically to work with these types of subjective issues. Results revealed 10 major themes involving both intrapsychic and relational features prior, during and …

Eliciting Awe In The Spectator: The Case Of A Dhrupad-Based Dance Performance, Alfonso Santarpia, Andrée Martin, Armando Menicacci, Pierre De Oliveira, Daniel Lemieux, Laurence Éthier, Caroline Charbonneau, Bruno Pucella, Christophe Flambard, Les Frères Gundecha, Louis-Charles Lusignan, Alice Bourgasser, Élisabeth-Anne Dorléans, Ariane Dubé-Lavigne, Angélique Poulin Jan 2022

Eliciting Awe In The Spectator: The Case Of A Dhrupad-Based Dance Performance, Alfonso Santarpia, Andrée Martin, Armando Menicacci, Pierre De Oliveira, Daniel Lemieux, Laurence Éthier, Caroline Charbonneau, Bruno Pucella, Christophe Flambard, Les Frères Gundecha, Louis-Charles Lusignan, Alice Bourgasser, Élisabeth-Anne Dorléans, Ariane Dubé-Lavigne, Angélique Poulin

International Journal of Transpersonal Studies

This paper describes “Kalos, eîdos, skopeîn,” an immersive Dhrupad-based dance installation designed to elicit feelings of awe in the spectators, in a real-life artistic context. This study used a mixed-methods approach in order to explore spectators’ awe experience (N=45), using specific scales and interpretative phenomenological analysis. Results suggested that “Kalos, eîdos, skopeîn,” with its combination of nature motifs and the slow dance-walk associated with the Dhrupad music in the choreography, was able to produce awe-related moments in some spectators and inspire a degree of positive emotions. Our qualitative results viewed awe explicitly as a positive emotion and showed that generally …


Pilot Study Of The Effects Of Mobile Based Resonant Frequency Breathing On Cognitive Performance In Healthy Young Adults With Elevated Stress, Daniel Saldana Sep 2021

Pilot Study Of The Effects Of Mobile Based Resonant Frequency Breathing On Cognitive Performance In Healthy Young Adults With Elevated Stress, Daniel Saldana

Dissertations, Theses, and Capstone Projects

Objective: Prior research has shown a bidirectional relationship between breathing, emotions, behavior, and cognitive functions thought to be mediated by the autonomic nervous system (ANS). Studies have shown that deep or diaphragmatic breathing interventions are associated with improved affect and decreased stress levels, but little attention has been paid to the effects of breathing training on cognition. The few studies that have looked at this have shown improved attention, memory, and executive functioning as a result of breathing interventions. While suggestive of positive benefits, these studies used control groups that are either inactive or inappropriate for determining their respective mechanisms …


Posttraumatic Stress Disorder: Comparing Short-Term, Intensive Therapy To Traditional, Long-Term Therapy, Laura Gonzalez, Sean Kruckenberg Aug 2021

Posttraumatic Stress Disorder: Comparing Short-Term, Intensive Therapy To Traditional, Long-Term Therapy, Laura Gonzalez, Sean Kruckenberg

Electronic Theses, Projects, and Dissertations

ABSTRACT

Posttraumatic Stress Disorder (PTSD) is a mental health diagnosis that occurs following a traumatic event, and military veterans are at higher risk of exposure to hazardous or life-threatening situations that may result in psychological trauma. PTSD sufferers experience symptoms such as distressing memories, nightmares, flashbacks, hypervigilance, and heightened arousal. Individuals with PTSD also experience higher rates of depressive and substance use disorders, involvement with the justice system, and self-harm and suicide. Many agencies, such as the Department of Veteran’s Affairs (VA) provide treatment PTSD, however most programs experience dropout rates as high as 36%. Recent studies have shown that …


The Influence Of Resilience And Expressive Flexibility On Character Strengths And Virtues On Military Leadership In U.S. Military Cadets, Vasiliki Georgoulas-Sherry Jul 2021

The Influence Of Resilience And Expressive Flexibility On Character Strengths And Virtues On Military Leadership In U.S. Military Cadets, Vasiliki Georgoulas-Sherry

Journal of Wellness

Introduction: Character strengths and virtues are greatly revered in military leadership. However, there is no empirical work assessing the relationship of resilience and expressive flexibility, two essential psychological constructs crucial in nurturing mentally healthy individuals, also for successful officer development and military leadership.

Methods: Employing a cross-sectional design, this study recruited 107 participants (ages 18 to 22) from a private U.S. Military university. McGrath, Rashid, Park, and Peterson’s and Peterson and Seligman’s taxonomies of character strengths and virtues were measured. Self-reported resilience and expressive flexibility were additionally assessed.

Results: Results revealed McGrath et al.’s virtue of self-control and Peterson and …


Disinhibition And Persistent Maladaptive Behavior, Angela T. West Jun 2021

Disinhibition And Persistent Maladaptive Behavior, Angela T. West

Student Theses

Objective: There is an urgent need to reduce overpopulation in U.S. prisons, which are inundated with individuals needing substance use treatment. Research on both substance use and antisocial behaviors highlight maladaptive beliefs and behaviors, while also implicating disinhibition as an important factor. Disinhibition is a dynamic trait that can be targeted with therapeutic interventions. The current study explored the relationships between neurocognitive disinhibition, substance use, and recidivism among incarcerated men. The study hypothesized that disinhibition would be associated with history of substance use, history of antisocial behavior, and institutional misconduct, as well as predicting recidivism over and above history of …


Self-Regulated Study Time Allocation To Enhance Learning And Item Difficulty Compensation, Eylul Tekin May 2021

Self-Regulated Study Time Allocation To Enhance Learning And Item Difficulty Compensation, Eylul Tekin

Arts & Sciences Electronic Theses and Dissertations

Few studies have examined whether self-regulation of study time allocation is beneficial for learning. In four experiments, the present dissertation investigated the effectiveness of self-paced study relative to fixed-rate study in which subjects did not regulate their study time. More specifically, the present dissertation examined 1) whether self-paced study enhanced retention and item difficulty compensation (i.e., reduced retention differences between easy and difficult items) relative to fixed-rate study under different levels of monitoring accuracy, and 2) whether improving monitoring accuracy facilitated the effectiveness of self-paced study. In all experiments, subjects studied easy and difficult word pairs either under self-paced study …


The Effect Of Temporal Discounting And Loss Aversion On Mock Plea Bargain Decision-Making, Anisha Patel May 2021

The Effect Of Temporal Discounting And Loss Aversion On Mock Plea Bargain Decision-Making, Anisha Patel

Masters Theses, 2020-current

An overwhelming majority of criminal cases in the United States utilize plea bargaining (90-95%). A plea bargain is an agreement between a criminal defendant and a prosecuting attorney where the defendant agrees to plead guilty, or nolo contendre (no contest), to one or more charges to reduce or drop other charges. The decision to accept a plea bargain must be made by the defendant, so a defendant’s ability to make or communicate competent choices regarding a plea bargain is important. However, defendant decision-making in plea bargaining is not sufficiently prevalent in plea bargaining or decision-making literature. While factors such as …


A Study On The Positive And Negative Emotional Response Of Frequent And Non- Frequent Video Game Players, Heidi Francis May 2021

A Study On The Positive And Negative Emotional Response Of Frequent And Non- Frequent Video Game Players, Heidi Francis

Psychology | Senior Theses

Video games are a fun and popular outlet for many. They boost enthusiasm and can provide a form of entertainment, challenges, and confidence in players (Ceranoglu, 2010). Video games are an activity that bring a variety of feelings as players interact in a variety of ways. Many researchers study the negative effects of competitive and violent video games which often have been correlated with aggression (Dowsett & Jackson, 2019). There is less focus on the positive emotional responses but positive effects of videogames have been supported but consider other factors of influence such as well-being, motivation, social interaction, and violence …


It’S Not All Aces: The Role Of Negative Parental Influences And Criminal Thinking In Juvenile Offending Behaviors, Branna Humphrey May 2021

It’S Not All Aces: The Role Of Negative Parental Influences And Criminal Thinking In Juvenile Offending Behaviors, Branna Humphrey

Electronic Theses and Dissertations

The role of adverse childhood experiences (ACEs) and criminal thinking in causing criminal behavior has been explored extensively in criminal justice research. Based on the concepts of ACEs and the Psychological Inventory of Criminal Thinking Scale, the negative parental influences and criminal thinking styles of 1,354 juvenile offenders were examined to establish that negative parental influences and criminal thinking are separately associated with juvenile problem and offending behavior, and that criminal thinking mediates the relationship between negative parental influences and juvenile problem and offending behavior. Analyses showed support for criminal thinking as a pathway from negative parental influences to juvenile …


Creating Appropriate Clinical Guidelines For The Bilingual Population With Acquired Brain Injuries, Sophia L. Pena May 2021

Creating Appropriate Clinical Guidelines For The Bilingual Population With Acquired Brain Injuries, Sophia L. Pena

Dissertations

While there is a growing bilingual demographic in the United States, relatively little is known about treating this population should they experience a brain injury. This is a growing area of interest, as research has demonstrated that the acquisition of a second language promotes neuroplastic changes that then impact brain functioning pre- and post-brain-injury. Given bilingualism’s cognitive complexity, clinicians are left with challenges on how best to tailor treatment for brain-injured bilingual populations. Therefore, the focus of this review was to provide clinical recommendations to clinicians performing assessments with bilingual individuals with acquired brain injuries. The goal was for the …


“I Don’T See It That Way Anymore”: A Qualitative Study Of Significant Changes Of Mind, Austin C. Archer Mar 2021

“I Don’T See It That Way Anymore”: A Qualitative Study Of Significant Changes Of Mind, Austin C. Archer

The Qualitative Report

The specific aim of the study is to explore the cognitive and emotional phenomena which accompany profound changes of perspective that people have. I would like to understand the change in a person’s thinking and in what way the person experiences these changes, whether it is a change in belief or a worldview. I would also like to understand whether external factors such as that facilitate these profound changes. Using a phenomenological approach, I interviewed eight adult participants in depth regarding changes to their worldview. I examined three phases of change, namely pre-change phase, the change phase, and the post-change …


How Multidimensional Is Emotional Intelligence? Bifactor Modeling Of Global And Broad Emotional Abilities Of The Geneva Emotional Competence Test, Daniel Simonet, Katherine E. Miller, Kevin Askew, Kenneth Sumner, Marcello Mortillaro, Katja Schlegel Mar 2021

How Multidimensional Is Emotional Intelligence? Bifactor Modeling Of Global And Broad Emotional Abilities Of The Geneva Emotional Competence Test, Daniel Simonet, Katherine E. Miller, Kevin Askew, Kenneth Sumner, Marcello Mortillaro, Katja Schlegel

Department of Psychology Faculty Scholarship and Creative Works

Drawing upon multidimensional theories of intelligence, the current paper evaluates if the Geneva Emotional Competence Test (GECo) fits within a higher-order intelligence space and if emotional intelligence (EI) branches predict distinct criteria related to adjustment and motivation. Using a combination of classical and S-1 bifactor models, we find that (a) a first-order oblique and bifactor model provide excellent and comparably fitting representation of an EI structure with self-regulatory skills operating independent of general ability, (b) residualized EI abilities uniquely predict criteria over general cognitive ability as referenced by fluid intelligence, and (c) emotion recognition and regulation incrementally predict grade point …


Pupillary Effects During Retrieval: Influenced By Cognitive Load And Strength Of Memory, Valentina Pinilla Jan 2021

Pupillary Effects During Retrieval: Influenced By Cognitive Load And Strength Of Memory, Valentina Pinilla

Mahurin Honors College Capstone Experience/Thesis Projects

Memory retrieval is influenced by cognitive processes that occur during encoding, some of which can be measured with pupillary responses. For example, during retrieval, pupils dilate more to previously-seen old items compared to new items, a phenomenon called the pupil old/new effect. Encoding variables that influence the strength of the memory trace for encoded stimuli play a role in successful discrimination of new versus old items. Additionally, the cognitive load during encoding (i.e., the effort needed to encode information), also impacts memory success by taking up mental resources needed to successfully encode information. In this study, I conducted a meta-analysis …


Attribute-Based Choice, Francine W. Goh, Jeffrey R. Stevens Jan 2021

Attribute-Based Choice, Francine W. Goh, Jeffrey R. Stevens

Jeffrey Stevens Publications

Alternative-based approaches to decision making generate overall values for each option in a choice set by processing information within options before comparing options to arrive at a decision. By contrast, attribute-based approaches compare attributes (such as monetary cost and time delay to receipt of a reward) across options and use these attribute comparisons to make a decision. Because they compare attributes, they may not use all available information to make a choice, which categorizes many of them as heuristics. Choice data have suggested that attribute-based models can better predict choice compared to alternative-based models in some situations (e.g., when there …


Exercise Shifts Hypothetical Food Choices Toward Greater Amounts And More Immediate Consumption, Karsten Koehler, Safiya E. Beckford, Elise Thayer, Alexandra R. Martin, Julie B. Boron, Jeffrey R. Stevens Jan 2021

Exercise Shifts Hypothetical Food Choices Toward Greater Amounts And More Immediate Consumption, Karsten Koehler, Safiya E. Beckford, Elise Thayer, Alexandra R. Martin, Julie B. Boron, Jeffrey R. Stevens

Jeffrey Stevens Publications

Although exercise modulates appetite regulation and food intake, it remains poorly understood how exercise impacts decision-making about food. The purpose of the present study was to assess the impact of an acute exercise bout on hypothetical choices related to the amount and timing of food intake. Forty-one healthy participants (22.0 ± 2.6 years; 23.7 ± 2.5 kg/m 2 , 56% female) completed 45 min of aerobic exercise and a resting control condition in randomized order. Food amount preferences and intertemporal food preferences (preference for immediate vs. delayed consumption) were assessed using electronic questionnaires with visual food cues. Compared to rest, …


Improving Measurements Of Similarity Judgments With Machine-Learning Algorithms, Jeffrey R. Stevens, Alexis Polzkill Saltzman, Tanner Rasmussen, Leen-Kiat Soh Jan 2021

Improving Measurements Of Similarity Judgments With Machine-Learning Algorithms, Jeffrey R. Stevens, Alexis Polzkill Saltzman, Tanner Rasmussen, Leen-Kiat Soh

Jeffrey Stevens Publications

Intertemporal choices involve assessing options with different reward amounts available at different time delays. The similarity approach to intertemporal choice focuses on judging how similar amounts and delays are. Yet we do not fully understand the cognitive process of how these judgments are made. Here, we use machine-learning algorithms to predict similarity judgments to (1) investigate which algorithms best predict these judgments, (2) assess which predictors are most useful in predicting participants’ judgments, and (3) determine the minimum number of judgments required to accurately predict future judgments. We applied eight algorithms to similarity judgments for reward amount and time delay …


Excluder: An R Package That Checks For Exclusion Criteria In Online Data, Jeffrey R. Stevens Jan 2021

Excluder: An R Package That Checks For Exclusion Criteria In Online Data, Jeffrey R. Stevens

Jeffrey Stevens Publications

Collecting survey data online can result in low-quality data. Survey participants may not complete the survey, may complete the survey too quickly or slowly, may not reside in the country they claim, or may use unacceptable screen types. Also, online surveys are plagued by automated bots attempting to complete the surveys while offering worthless data. Researchers collecting online data may want to check their data for these and other potential criteria to exclude problematic data entries. The excluder package uses three main function types to mark, check, and exclude data based on seven different exclusion criteria.
