The Effects Of Moral Message Framing On Political Ideology, Matthew Christiansen Jan 2018

The Effects Of Moral Message Framing On Political Ideology, Matthew Christiansen

All Master's Theses

There is disagreement as to whether and to what extent the American public is becoming more polarized, but certain issues such as climate change have been found to be polarizing. However, ideologically congruent moral message framing has been shown to moderate attitudes towards climate change and may provide a method to reduce polarization and moderate extreme attitudes. The current study attempted to broaden previous findings to investigate whether moral message framing could result in not only shifting relevant attitudes, but political ideology as a whole. Operating under Moral Foundations Theory (Haidt & Graham, 2007) two proenvironmental messages were constructed using …


Sign Modulation By Chimpanzees To Produce Interrogatives, Kailie Dombrausky Jan 2018

Sign Modulation By Chimpanzees To Produce Interrogatives, Kailie Dombrausky

All Master's Theses

Native signers of American Sign Language produce interrogatives by holding signs for an extended duration while employing the questioning look. The questioning look is defined as raised eyebrows, a tilted head, and direct eye contact maintained for the duration of the utterance. Chimpanzees who communicate using signs have demonstrated modulation of signs including held sign, raised brow, and eye gaze. The present study used archived video data to compare the duration of signs when the chimpanzees did or did not employ the questioning look. In both single and multi-sign utterances, the chimpanzees held their signs for a mean of 0.6 …


Effects Of Emotion And Construal Level On Obesity Stigma, Peyton D. Curtis Jan 2018

Effects Of Emotion And Construal Level On Obesity Stigma, Peyton D. Curtis

Honors Theses

We conducted the present study to determine how emotion and construal level contribute to obesity bias. Specifically, we examined if different emotions, such as disgust, sadness, and happiness, played a role in several different judgments of an obese versus thin individual: 1) general impressions, 2) supporting a friend, and 3) endorsing personal versus biological/environmental causes for weight. We also investigated whether a self me construal or collective we construal influenced these judgments. We additionally considered whether emotion and these construal levels would interact to influence such judgments. The current work found that emotion and construal level did not interact to …


Investigating Differing Degrees Of Foxo3a Expression In Adult Neural Stem Cells Between Age Groups In Zebrafish, Francis G. Bacik Jan 2018

Investigating Differing Degrees Of Foxo3a Expression In Adult Neural Stem Cells Between Age Groups In Zebrafish, Francis G. Bacik

Cal Poly Humboldt theses and projects

One factor influencing organismal longevity is the activity of transcription factors of the “fork head domain” family, otherwise known as “Forkhead box” (Fox) proteins. Studies of the four isoforms of the “O” subclass of Fox proteins found in human genes have revealed a direct relationship between FoxO3a-dependent gene expression and the conservation of neural stem cell (NSC) in the adult brain, specifically in the subgranular zone of the dentate gyrus in the hippocampus and the subventricular zone of the cortex. This transcription factor has also been shown to regulate apoptosis in nervous tissue during embryonic development in zebrafish. The current …


Test Of Bpa's Estrogenic Effects On Brain Aromatase Expression, Neural Activity, And Locomotive Behavior In Zebrafish Larvae, Ryan J. Mcauley Jan 2018

Test Of Bpa's Estrogenic Effects On Brain Aromatase Expression, Neural Activity, And Locomotive Behavior In Zebrafish Larvae, Ryan J. Mcauley

Cal Poly Humboldt theses and projects

Bisphenol A (BPA) is a well-known endocrine disrupting chemical that mimics the effects of estrogens. Aromatase B (Cyp19a1b) is a brain-specific enzyme that converts testosterone to estrogen and is highly upregulated in response to estrogen receptor activation localized to radial glial cells. During embryonic zebrafish development, there is a small window of time denoted by an increase in neurogenesis and estrogen receptor activity. Previous studies have demonstrated that a low dose BPA exposure (0.1µM) during this window causes hyperlocomotion in larval zebrafish, yet no further explanation for this behavior change has been described. The purpose of this study was to …


What Type Of Training Predicts Adherence To Cbt-I Among Professionals Specializing In The Treatment Of Insomnia?, Mark D. Delguercio Jan 2018

What Type Of Training Predicts Adherence To Cbt-I Among Professionals Specializing In The Treatment Of Insomnia?, Mark D. Delguercio

PCOM Psychology Dissertations

This study explored the relationship between certain educational and professional variables that influence the adherence to empirically supported practices in cognitive-behavioral therapy for insomnia (CBT-I). The variables of interest included the practitioner’s level of training as measured by the number of hours of advanced training in CBT-I, the total number of hours practicing CBT-I out of the total annual clinical practice hours, and the total number of years practicing CBT-I. The final variable of interest was treatment preference and practice knowledge. The study used a one-time, cross-sectional, web-based survey. The participants consisted of 165 mental health and medical professionals of …


Instructing Students With Pediatric And Mental Health Conditions: Predictors Of Teachers’ Self-Efficacy, Rachel Allen Jan 2018

Instructing Students With Pediatric And Mental Health Conditions: Predictors Of Teachers’ Self-Efficacy, Rachel Allen

PCOM Psychology Dissertations

Teachers face unique challenges when teaching children who have individualized education plans (IEPs) and/or 504 plans, including managing problematic behaviors and knowing about the symptoms and accommodations necessary when children present with health conditions. The factors that predict teachers’ self-efficacy when working with these children have not been established. This was a quantitative retrospective design utilizing a survey of teachers’ past experiences teaching children with IEP’s and/or 504 plans. K-8 elementary school teachers were surveyed using the Teacher Self-Efficacy Scale for Children with IEP/504 Plans (2017), which was developed by the authors and was adapted from a previous measure, the …


Understanding Transgender Prejudice Through The Lens Of Emotion, Holly N. Fitzgerald Jan 2018

Understanding Transgender Prejudice Through The Lens Of Emotion, Holly N. Fitzgerald

Graduate Theses, Dissertations, and Problem Reports (ETD)

Transgender individuals report facing incidents of discrimination often in all aspects of their lives (James et al., 2016). A potential way to combat the discrimination transgender people face is through reducing transgender prejudice. However, it is not yet known what comprises transgender prejudice. Some research has found that emotions may be the more predominant determinant of prejudice, as opposed to stereotypes (Dasgupta, Desteno, Williams, & Hunsinger, 2009; Haddock, Zanna, & Esses, 1993a; Smith, 1993). Thus, the present research sought to identify the specific emotions associated with transgender prejudice. In Study 1, participants completed explicit and implicit measures of prejudice and …

Selection And Implementation Of Skill Acquisition Programs By Special Education Teachers And Staff For Students With Autism Spectrum Disorder, Tiffany Kodak, Tom Cariveau, Brittany A. Leblanc

Psychology Faculty Research and Publications

The present investigation examined special education teachers’ selection and use of teaching strategies for receptive identification training with children with autism spectrum disorder (ASD) in their classrooms. Teachers first responded to a survey in which they provided examples of receptive identification tasks taught in their classrooms, rated the efficacy of teaching strategies, described how they determined whether skills were mastered, listed any assessments they conducted to identify relevant prerequisite skills prior to receptive identification training, described how they selected teaching strategies for use in their classrooms, and listed their years of experience as a teacher and working with children with …


Effects Of Delay And Signals On Choice Between Delayed Food Alone And Immediate Food With Delayed Shock, Forrest James Toegel Jan 2018

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 …

by

THOMAS MICHALOS

December 2018

Advisor: Dr. John Pietrofesa

Major: Counselor Education

Degree: Doctor of Philosophy

Clinical supervision is an integral part of the education and formation of a counselor. The following study focuses on measuring to what degree clinical supervision and experiences relates to the self-efficacy of counselors-in-training. A sample of 106 graduate level counselor education students were surveyed. Those students who have received clinical supervision had significantly higher levels of self-efficacy than who have never experienced clinical supervision. Additionally for those students in the …


The Heterogeneity Of Victim Impact Statements: A Content Analysis Of Capital Trial Sentencing Penalty Phase Transcripts, Bryan Myers, Narina Nuñez, Benjamin Wilkowski, Andre Kehn, Katheirne Dunn Jan 2018

The Heterogeneity Of Victim Impact Statements: A Content Analysis Of Capital Trial Sentencing Penalty Phase Transcripts, Bryan Myers, Narina Nuñez, Benjamin Wilkowski, Andre Kehn, Katheirne Dunn

Psychology Faculty Publications

Victim impact statements (VISs) are controversial in capital sentencing proceedings largely due to their questionable relevance to sentencing, the concern that characterizations of the victim may lead to arbitrary sentencing judgments, and the belief that the emotional nature of this evidence may be inflammatory. A sample of 192 capital trial VIS transcripts was analyzed for content as well as a linguistic analysis of emotionality. The findings reveal that these statements are highly varied, including their format, length, and relation between the witness and the victim. Despite a legislative mandate that they address the emotional, financial, and physical suffering experienced by …

Do Different Music Genres Differentially Affect Autonomic Activity? How Music And Sound Affect Autonomic Activity Aroused By Visual Stimuli, Andrew Manson Jan 2018

Do Different Music Genres Differentially Affect Autonomic Activity? How Music And Sound Affect Autonomic Activity Aroused By Visual Stimuli, Andrew Manson

Online Theses and Dissertations

The primary researcher sought to determine whether different genres of music would differentially influence measures of autonomic nervous system activity (heart rate, galvanic skin response) while viewing visual stimuli in a sample of college students. All participants listened to the same songs and music genres and viewed the same International Affective Picture System (IAPS) images. Autonomic nervous system activity was recorded by attaching electrodes to participants' non-dominant hand and torso. Music order presentation and picture order presentation were randomly determined by E-Prime. Heart rate and skin conductance responses were both significant, with melodic metal music inducing greater intensity of responses …


Increasing Chance-Based Uncertainty Reduces Heavy Drinkers’ Cognitive Reactance To Web-Based Personalized Normative Feedback, Sarah C. Boyle, Andrew M. Earle, Nate Mccabe, Joseph W. Labrie Jan 2018

Increasing Chance-Based Uncertainty Reduces Heavy Drinkers’ Cognitive Reactance To Web-Based Personalized Normative Feedback, Sarah C. Boyle, Andrew M. Earle, Nate Mccabe, Joseph W. Labrie

Heads Up!

Objective: Despite its prominence in the health communication literature, psychological reactance has rarely been considered as a factor that may undermine web-based Personalized Normative Feedback (PNF) alcohol interventions for college students. This study built on recent gamification work to examine how chance-based uncertainty, a popular game mechanic associated with motivation and attention in digital games for learning, might be leveraged to reduce the psychological reactance experienced by heavy drinking students receiving alcohol PNF, thereby leading to larger reductions in their alcohol consumption. Method: Psychological reactance, perceptions of norms, and drinking behaviors were assessed during a 3-week period following random assignment …


Wordnet-Feelings: A Linguistic Categorisation Of Human Feelings, Advaith Siddharthan, Nicolas Cherbuin, Paul J. Eslinger, Kasia Kozlowska, Nora Murphy, Leroy Lowe Jan 2018

Wordnet-Feelings: A Linguistic Categorisation Of Human Feelings, Advaith Siddharthan, Nicolas Cherbuin, Paul J. Eslinger, Kasia Kozlowska, Nora Murphy, Leroy Lowe

Psychological Science Faculty Works

In this article, we present the first in depth linguistic study of human feelings. While there has been substantial research on incorporating some affective categories into linguistic analysis (e.g. sentiment, and to a lesser extent, emotion), the more diverse category of human feelings has thus far not been investigated. We surveyed the extensive interdisciplinary literature around feelings to construct a working definition of what constitutes a feeling and propose 9 broad categories of feeling. We identified potential feeling words based on their pointwise mutual information with morphological variants of the word `feel' in the Google n-gram corpus, and present a …


Preserved Consciousness In The Absence Of A Cerebral Cortex, The Legal And Ethical Implications Of Redefining Consciousness And Its Neural Correlates: A Case For A Subcortical System Generating Affective Consciousness, Shadia Kawkabani Jan 2018

Preserved Consciousness In The Absence Of A Cerebral Cortex, The Legal And Ethical Implications Of Redefining Consciousness And Its Neural Correlates: A Case For A Subcortical System Generating Affective Consciousness, Shadia Kawkabani

Williams Honors College, Honors Research Projects

Historically, the scientific and medical communities have taken a corticocentric view on consciousness, emphasizing the need for a cortex in producing the conscious experience. The preserved consciousness observed in hydranencephalic children and decorticated rats suggests that some form of consciousness may be produced by a subcortical network. The brainstem, a phylogenetically ancient and conserved brain structure, could serve as the major integrative machinery to produce this form of consciousness, which is called affective consciousness—the evolutionary antecedent to the reflective consciousness that allows humans to reflect on their experiences. The functional convergence of the brainstem with the amygdala, motor system, and …

Browse all Theses and Dissertations

This work describes an Ecological Interface Design (EID) comparison of five displays (Alphanumeric, 2D and 3D Aggregate, Radial, and Treemap) on accuracy and latency performance for simple cyber network data analysis tasks. Twenty students from the Computer Science and Engineering Department at Wright State University participated for compensation. Questions (n = 12) ranged from global to specific aspects of the data and required two types of responses: numerical estimates and binary visual judgments. EID principles of attunement and specificity (Bennett & Flach, 2011) guided the interpretation of results. Participants answered faster when the display's visual forms (vertical extent, area, or …


Symbol Grounding In Social Media Communications, Andrew J. Hampton Jan 2018

Symbol Grounding In Social Media Communications, Andrew J. Hampton

Browse all Theses and Dissertations

Social media data promise to inform the disaster response community, but effective mining remains elusive. To assist in the analysis of community reports on disaster from social media, I draw on an integrated model of psycholinguistic theory to investigate the patterns by which language use changes as a function of environmental influence. Using social media corpora from several disasters and non-disasters, I examine variations in patterns of lexical choice between domain independent paired antonyms with respect to an Internet-specific base rate to determine generic sentinels of breach of canonicity. I examine social media content with respect to disaster proximity and …


Exploring The Influence Of Meditation Experience On Stress Responses And Empathy: The Mediating Role Of Self-Expansion, Jennifer N. Baumgartner Jan 2018

Exploring The Influence Of Meditation Experience On Stress Responses And Empathy: The Mediating Role Of Self-Expansion, Jennifer N. Baumgartner

Browse all Theses and Dissertations

The purpose of the present research was to examine the influence of meditation experience on biopsychosocial responses to stress, empathy, and sense of self. An expanded sense of self was examined as a pathway through which meditation experience influences appraisals, affect, and empathy. It was expected that meditation experience would predict greater challenge stressor appraisals in response to an acute psychosocial stressor and associated affective, behavioral, and psychophysiological stress outcomes. In addition, it was expected that greater meditation experience would predict higher trait empathy and empathic accuracy. Participants (N = 110) included experienced meditators from a variety of practices and …


The Many Faces Of Fear And Vigilance, Guy Beauchamp Jan 2018

The Many Faces Of Fear And Vigilance, Guy Beauchamp

Animal Sentience

In the target article, I examined the relationship between vigilance and fear in prey animals. The joint occurrence of vigilance and other physiological responses to fear, such as increased heart rate and stress hormone release, would bolster the idea that vigilance can be a useful marker of fear. Nevertheless, a common theme in much of the empirical research is an uncoupling of vigilance and physiological correlates of fear. The commentators suggest several ways to refine the concepts of vigilance, fear, and risk. I discuss these refinements, which in the end will prove useful to assess further the relationship between vigilance …


A Behavioral Mechanistic Investigation Of The Role Of 5-Ht1a Receptors In The Mediation Of Rat Maternal Behavior, Xiaonan Li, Xiaojing Ding, Ruiyong Wu, Leilei Chen, Jun Gao, Gang Hu, Ming Li Jan 2018

A Behavioral Mechanistic Investigation Of The Role Of 5-Ht1a Receptors In The Mediation Of Rat Maternal Behavior, Xiaonan Li, Xiaojing Ding, Ruiyong Wu, Leilei Chen, Jun Gao, Gang Hu, Ming Li

Department of Psychology: Faculty Publications

Previous work suggests that 5-HT1A receptors play a special role in rodent maternal aggression, but not in other aspects of maternal care (e.g. pup retrieval and nest building). The present study re-assessed the basic effects of 5-HT1A activation or blockade on various maternal responses in postpartum female rats. We also examined the possible behavioral mechanisms underlying the maternal effects of 5-HT1A. Sprague–Dawley mother rats were injected with a 5-HT1A agonist 8-OH-DPAT (0.1, 0.5 or 1.0 mg/kg, sc), a 5-HT1A antagonist WAY-101405 (0.1, 0.5 or 1.0 mg/kg, sc) or 0.9% saline solution on postpartum days …


Questioning The Modality Of The Occipital Lobe, William J. Brixius Jan 2018

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 …


Neurochemistry, Physiology, And Behavior In A Model Of Gulf War Illness, Victoria A. Macht Jan 2018

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 …


Exercise As A Therapeutic For Hiv-1-Associated Neurocognitive Deficits, Michael N. Cranston Jan 2018

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 …


Sex Differences In Predicting Nicotine-Induced Behavioral Sensitization From Habituation To Novelty And Initial Drug Response, Jessica Illenberger Jan 2018

Sex Differences In Predicting Nicotine-Induced Behavioral Sensitization From Habituation To Novelty And Initial Drug Response, Jessica Illenberger

Theses and Dissertations

Administration of nicotine evokes an immense mesolimbic dopamine response that progressively increases, or sensitizes, with repeated drug exposure and can be monitored indirectly through rodent’s motor activity. Sex differences in observed rates of behavioral sensitization in rodents appear to be consistent with epidemiological reports of smoking in humans, which indicate that females are more sensitive to the repeated effects of nicotine. Sex differences in sensitization to nicotine may explain why females progress towards addiction faster than males and so in order to effectively treat and prevent nicotine use in vulnerable populations, it is necessary to identify other factors that can …


An Investigation Of Brain Normalization And Lesion Compensation Techniques Applied To Stroke, Taylor Hanayik Jan 2018

An Investigation Of Brain Normalization And Lesion Compensation Techniques Applied To Stroke, Taylor Hanayik

Theses and Dissertations

One of the most ubiquitous steps in neuroimaging is the normalization of brain images. The process of normalization attempts to match any given brain to a standardized template image (e.g. the MNI 152 image). However, clinical images such as those from stroke participants present many challenges when we attempt to warp them to the space of template images, which are typically representative of neurologically healthy individuals. Many software packages exist to facilitate normalization of brain images, but most have limited options available to compensate for brain injury, which is often disruptive to these algorithms. Of the injury compensation methods that …


Normative Data For Four Neuropsychological Tests In A Sample Of Adults Who Are Illiterate And From Latin America, Alejandra Morlett Paredes Jan 2018

Normative Data For Four Neuropsychological Tests In A Sample Of Adults Who Are Illiterate And From Latin America, Alejandra Morlett Paredes

Theses and Dissertations

Neuropsychological tests are standardized tasks used to measure psychological functioning that is associated with a particular brain structure. These tests often are used in diagnosing a cognitive deficiency resulting from brain injuries. Currently, there are a limited number of studies that have focused on standardization of neuropsychological tests in Latin America. Therefore, the vast majority of cognitive tests used in the evaluation of patients with brain damage have no normative parameters adjusted to the cultural characteristics of Latinos and Latinas. As a result, neuropsychological diagnoses among this population may be inadequate, and evaluation of rehabilitation program effectiveness limited. The importance …
