Potential Candidates For Treating Deficits Associated With Developmental Ethanol Exposure In A Rodent Model: Solidago Nemoralis & Dimethoxybenzylidene-Anabasine, Logan James Fields

Theses and Dissertations--Psychology

Prenatal alcohol exposure (Fetal Alcohol Syndrome [FAS] and Fetal Alcohol Spectrum Disorders [FASD’s]) represents the leading preventable cause of intellectual disabilities in the western world, with FASDs estimated to affect approximately 2-5% of live births in the United States at an approximate annual cost of $3.6 billion (CDC, 2015; May et al., 2009). Ethanol (ETOH) exposure during development can lead to a variety of long-term behavioral impairments including problems with executive functioning, motor coordination, spatial learning, attention, and hyperactivity (Jones, 2011; Mattson & Riley, 1998). Much research has been conducted to develop pharmacological and/or environmental interventions to reduce these deficits, …

Political Essentialism And Affective Polarization, Chase Wilson

Dissertations

Affective polarization, the phenomenon of liberals and conservatives treating each other as disliked outgroups, is increasingly intense (Iyengar & Westwood, 2015; Pew, 2016). In the present research, I used the construct of psychological essentialism (Medin & Ortony, 1989) to help understand this intergroup phenomenon. Specifically, I measured political essentialism, or the belief that political ideologies are strongly determined, informative, discrete and/or immutable, and tested the relationship between these beliefs and affective polarization. I approached this question with both correlational and experimental methods. In a correlational study, political essentialism overall is found to covary positively with affective polarization and social avoidance …

Cognitive Remediation Of Working Memory Deficits In Children With Chronic Health Conditions: Tailoring Cogmed Training To Address Barriers To Adherence, Kelsey Smith

Theses and Dissertations

Objective: Children with sickle cell disease (SCD) and cancer are at risk for working memory impairment due to the disease and treatment. However, inconsistency in adherence to cognitive training programs conducted with this population suggests that adaptations are necessary in order to improve the effectiveness of this intervention. In addition, it is unclear whether gains in working memory translate to improvement in classroom functioning.

Methods: Children engaged in cognitive training exclusively over the summer in order to improve adherence to Cogmed Working Memory Training. A total of 17 children ages 7- 17 with a diagnosis of SCD (n = 14) …

Independent And Interactive Associations Of Negative Affect, Restraint, And Impulsivity In Relation To Binge Eating Among Women, Tyler B. Mason, Kathryn E. Smith, Jason M. Lavender, Robin J. Lewis

Psychology Faculty Publications

There is growing recognition that impulsivity may serve as an underlying risk factor for binge eating. In addition, the association of impulsivity with binge eating may be moderated by other affective and cognitive risk factors. This study examined independent and interactive associations of negative affect, dietary restraint, and facets of impulsivity with binge eating. A diverse sample of 566 undergraduate women completed online questionnaires of study variables. Results revealed a three-way interaction of negative affect, dietary restraint, and attentional impulsivity in relation to binge eating. Women who were high on each of these three variables reported the greatest levels of …

Assessment Of Peripheral Bdnf Levels Over 30 Days, Sally Hang

Cal Poly Humboldt theses and projects

Brain health, and the benefits of exercise have been linked to the biological signaling molecule called brain-derived neurotrophic factor (BDNF). Animal and human studies have provided some support for physical exercise as a mechanism for increasing BDNF levels. However, results have been inconsistent, which may be attributed in part to incomplete information about normal variation in circulating peripheral BDNF levels. This investigation examined capillary-drawn whole blood samples from nine healthy adult participants over 30 days with the goal of documenting variability in resting BDNF levels and changes that may be attributed to physical exercise. It was hypothesized that BDNF concentrations …

Using Functional Infrared Thermal Imaging To Measure Stress Responses, Julia Tenaya Kandus

Cal Poly Humboldt theses and projects

The stress response reflects a coordinated pattern of physiological changes that serves the adaptive function of increasing an organism’s ability to cope with situations that require action or defense. The changes in blood flow associated with the stress response may be detectable using the relatively new research technique of functional infrared thermal imaging (fITI). The present study was designed to determine the time-course and topography of temperature changes in human faces during the experience of a stressor. Infrared images were taken from 29 female participants while they completed the mental arithmetic component of the Trier Social Stress Test (TSST). Continuously …

Woods, John T. Walkup, Alan L. Peterson, Sabine Wilhelm, Adam B. Lewin, James T. Mccracken, James F. Leckman, Lawrence Scahill

Psychology Faculty Research and Publications

Objective To examine the internal consistency and distribution of the Yale Global Tic Severity Scale (YGTSS) scores to inform modification of the measure.

Methods This cross-sectional study included 617 participants with a tic disorder (516 children and 101 adults), who completed an age-appropriate diagnostic interview and the YGTSS to evaluate tic symptom severity. The distributions of scores on YGTSS dimensions were evaluated for normality and skewness. For dimensions that were skewed across motor and phonic tics, a modified Delphi consensus process was used to revise selected anchor points.

Results Children and adults had similar clinical characteristics, including tic symptom severity. …

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 …

Examining Parental Scaffolding In Computer Based Contexts As A Function Of Task Difficulty And Mobility Of Computer Device, Domenica De Pasquale

Theses and Dissertations (Comprehensive)

Technology is part of everyday life for most adults and children. Digital technologies allow children to engage with technology and the digital world earlier in their development than previously experienced (Orlando, 2011; Plowman, Stevenson, Stephen, & McPake, 2012). Two studies were conducted to explore joint media-based interactions of parents and their children. Parental views, age, gender, experience and familiarity with technology were considered in conjunction with parent-child interactions when engaged with stationary and mobile computers and when engaged with easy and difficult to navigate software. Study 1 employed self-report measures consistent with the wider body of literature available regarding early …

Understanding Emotions In The Workplace: A Critical Examination Of The Role Of Emotions In Justice And Negotiation, Annika Hillebrandt

Theses and Dissertations (Comprehensive)

The central role of emotions in organizations, once underrecognized and underappreciated by organizational scholars, has attracted a great amount of research interest in recent years. Despite this important development, I argue that a number of critical questions have remained unaddressed, which limits our ability to predict the outcomes of emotions for individuals and organizations as well as describe employees’ subjective experiences at work. In this dissertation, I contribute to the understanding of the role of emotions in the workplace by identifying critical gaps in the emotions literature, integrating theories from different literatures to address these gaps, empirically comparing the interpersonal …

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 …

Abuse Liability Of An Electronic Cigarette In Traditional Cigarette Smokers, Sarah F. Maloney

Theses and Dissertations

Electronic cigarettes have grown in popularity across the U.S. and concerns have been raised about their abuse liability. The purpose of the current study was to evaluate and compare the abuse liability of an electronic cigarette with and without nicotine to a nicotine inhaler (the Nicotrol inhaler) and participants’ own brand of cigarettes. A total of 24 smokers attended four sessions in which the abuse liability of each product was examined using the Multiple-Choice Procedure (MCP), nicotine delivery, nicotine abstinence symptom suppression, and subjective reinforcing effects. Results revealed that the nicotine containing and non-nicotine containing electronic cigarette had a higher …

Reliability And Validity Of The Humboldt Food Addiction Questionnaire, Sarah R. Taylor

Cal Poly Humboldt theses and projects

Current research shows that foods high in sugar, salt, and fat can illicit addictive responses (Pursey, Stanwell, Gearhardt, Collins, & Burrows, 2014). Although measures of overeating pathology exist, only a few are dedicated to food addiction. Two of these measures are the Yale Food Addiction Scale (YFAS; Gearhardt, Corbin, & Brownell, 2009b) and the Eating Behaviors Questionnaire (EBQ; Merlo, Klingman, Malasanos, & Silverstein, 2009). Given the shortage of food addiction measures, the Humboldt Food Addiction Questionnaire (HFAQ) was developed to supplement the need for additional tools. Recruited from both a university and online, 626 participants completed this study. Reliability of …

Differential Predictors Of Opposition To Same-Sex Marriage And Sexual Prejudice, Latishia E Y Jett-Dias

Cal Poly Humboldt theses and projects

This study investigated attitudes toward same-sex marriage and its beneficiaries from the frameworks of social dominance orientation (SDO) and political conservatism. Unlike past research that focused mainly on sexual prejudice, the current paper explicitly examined both opposition to same-sex marriage and sexual prejudice. Additionally, the current study explored subcomponents of SDO (i.e., opposition to equality [OEQ] and group-based dominance [GBD]). Study One examined relationships and predictive difference between attitudes toward same-sex marriage and its beneficiaries before California legalized same-sex marriage. Study Two addressed attitudes before and recently after California legalized same-sex marriage. OEQ, GBD, and conservatism predicted opposition to same-sex …

The Influence Of Quality Of Education On A Regression-Based Method Of Premorbid Estimated Intelligence, Elizabet Santana Marmon-Halm

PCOM Psychology Dissertations

The physical, cognitive, behavioral, and emotional sequelae of brain injury have been shown to exert a substantial negative impact on everyday work-related and social functioning. Accordingly, accurate measurement of any associated cognitive decline is of paramount importance, and clinicians often face the challenge of estimating the patient’s level of intellectual functioning prior to the brain pathology. This study examined the influence of environmental factors, such as education quality on a demographically based formula for estimating premorbid intelligence and focused primarily on an adjusted variable (reading level vs. years of education). The results showed that for the entire sample of the …

Latent Structure Of The Wisconsin Card Sorting Test In Psychiatrically Hospitalized Youth, Jane S. Studeny

Antioch University Dissertations & Theses

The aims of this study were to explore the latent factor structure of WCST performance in psychiatrically hospitalized youth, and to investigate associations between latent factors and various psychiatric, psychological, and neuropsychological variables. The results revealed a three-factor solution that is broadly attributed to executive abilities of problem solving, cognitive flexibility, and inhibitory control. The resulting three-factor solution accounted for 96% of the variance in the present study’s sample, and was comparable to results from similar studies in adult populations. Latent factors were associated with performance on a brief test of intelligence as well as to several measures of executive …

Case Study Of The Four-Year Neuropsychological Changes In An Elderly Male With Possible Chronic Traumatic Encephalopathy, Patrick Martin

Antioch University Dissertations & Theses

Research demonstrates that the brain's response to Traumatic Brain Injury (TBI) is variable with age and the effects of TBI on the elderly are a critical and global public health concern, from both a medical and a neuropsychological perspective. Currently, there is scant research on the effects of TBI, including Chronic Traumatic Encephalopathy (CTE), on the elderly. Specifically, there is a paucity of literature regarding longitudinal neuropsychological changes in elderly post- TBI individuals. This dissertation will present a Single Case Research Design (SCRD) analysis of an elderly individual with possible Chronic Traumatic Encephalopathy and the associated neuropsychological changes over 49-months. …

The Way We Say Sorry, Brie E. Everard

Antioch University Dissertations & Theses

People living with autism struggle with social interaction, social play, and communication. Over the last decade, technology-based interventions have been used as a way of teaching social skills to children with autism. To investigate these issues more thoroughly, three topics were the focus of this research: (a) the development of autism, (b) theory of mind, and (c) technology-based interventions. The information gained from studying these topics was used to create a technology-based intervention called The Way We Say Sorry (TWWSS). This intervention was created to help children with autism better understand the way sorry is used in the English language. …

Philosophical Ends To Scientific Means: Diagnosis And The Epistemology Of Psychology, Christopher Michael Johnson

Antioch University Dissertations & Theses

Modern scientific psychology continues to advance toward newer and greater discoveries of the inner workings of the human mind, posited in the belief that a universal objectivity exists if only to be found. Despite the professional emphasis on conducting psychological enterprises in this manner, the field has spent much of its formalized existence struggling to answer some of its most basic questions. This paper thoroughly explores the nature of a scientific psychology, while suggesting that psychology may find wisdom in its philosophical origins. It further suggests that psychology continue toward a postmodern epistemology, in which a unitary psychological reality is …

Knitting As An Adjunctive Treatment For Substance Use Disorder: A Mixed Methods Multiple Case Study, Aubriana M. Teeley

Antioch University Dissertations & Theses

Substance abuse disorder is a characterized by the presence of cognitive, behavioral, and physiological symptoms from substance use with continued use despite these consequences. It has serious individual and societal implications, such as negative health effects, overdose, poor work and school performance, negative impacts on relationships, and even death. Economic effects include more frequent use of emergency and hospital services as compared to peers without substance use disorder. A variety of treatments for substance use are available, including inpatient and outpatient programs accompanied by behavioral interventions, individual or group psychotherapy, or 12-step programs. However, there is no one treatment that …

"The Way To Become A Man": The Influence Of Commercial Sex On Male Psychosocial Development, Adrian Deluna Garcia

Antioch University Dissertations & Theses

Hegemonic masculinity and the negative consequences that it has on men and women continues to gain increasing attention in research and in popular culture. Particular attention is paid to the sexual violence that is perpetrated by men towards women, however, the research on men’s sexual development and its relationship to this sexual violence focuses largely on biological explanations. The feminist literature, however, on sexual violence offers a differing perspective, which includes the socialization processes that men undergo in their sexual development that lead them towards normalizing sexual violence. One of these processes is the existence and normalization of the commercial …

Combat Neuroses And The Battle Of Little Big Horn, Albert Winkler

Faculty Publications

Combat stress first became a subject of much academic inquiry in the 20th century, but soldiers certainly suffered from mental problems in the 19th century as well as a result of battle, including the Little Big Horn. The purpose of this study is to examine how the stress of the Little Big Horn disturbed the participating trooper mentally and how these men suffered from symptoms related to combat neurosis such as panic, insanity, and irrational behavior which the men demonstrated during the battle and afterward.

Using Instructed Response Times To Compare Inattentive Responding Across Paper And Online Modalities: Measuring Research Participant Inattention, Olivia B. Brooks

EWU Masters Thesis Collection

It is important to examine the equivalence of paper and online data collection methods across several domains. The current study compared paper versus online modalities from a data quality standpoint, with a specific focus on inattentive (i.e., careless) responding by using an easily-implemented method to capture participants’ careless responses: interspersing instructed response items (e.g., “Please select option 3, ‘Strongly disagree,’”) throughout a collection of 15 established measures. A between-subjects design compared the percentage of instructed response items missed (hence, inattentive responses) across three conditions: 1) lab paper, 2) lab online, and 3) non-lab online. The non-lab online condition was predicted …

Perceptions Of Obese African American Women Regarding Altering Traditional Soul Food Preparation, Patricia Young

Journal of Social, Behavioral, and Health Sciences

The obesity epidemic continues to be a major concern in the United States. The World Health Organization reported that 1.4 billion adults were either obese or overweight African American (AA) women have the highest incidence of obesity worldwide. A qualitative descriptive study was used to explore the perceptions of obese AA women about altering how they prepare soul food to make it healthier. The empowerment model and the health belief model were used to frame this study. Data were collected using a nonprobability purposeful sampling strategy. The sample for this study consisted of four focus groups with six to seven …

Characterizing Curiosity-Related Behavior In Bottlenose (Tursiops Truncatus) And Rough-Toothed (Steno Bredanensis) Dolphins, Malin K. Lilley, Amber J. De Vere, Deirdre B. Yeater, Stan A. Kuczaj

Psychology Faculty Publications (Archived)

Dolphins are frequently described as curious animals; however, there have been few systematic investigations of how dolphins behave when they are curious and the extent to which individual differences in curiosity exist in dolphins. Previous research has described individual differences in dolphins’ frequency of interactions with environmental enrichment as well as quantifying curiosity-related traits of dolphins via personality assessments, though behavioral observation and trait rating components have not been part of the same study. The present study describes two different experiments designed to elicit curiosity in 15 bottlenose (Tursiops truncatus) and 6 rough-toothed (Steno bredanensis) dolphins. In Experiment 1, dolphins …

Does Observational Learning Influence Spatial Pattern Learning?, Matthew Bruster

College of Graduate Studies: Theses & Dissertations

Previous studies have indicated both human and non-human animals come under control of a hidden spatial pattern when engaged in an open field search task, and rats appear to exhibit social learning in such tasks through the influence of a conspecific on their search behavior. Although human participants appear to perform similarly in both real-world and virtual environment versions of a spatial pattern search task, evidence from human participants for social learning in such a task remains lacking. The current experiments tested the influence of social learning (observational learning) on human performance in a spatial pattern learning task within a …

Sentient Plants? Nervous Minds?, Arthur S. Reber

Animal Sentience

The commentaries by Calvo (2018) and Mallatt & Feinberg (2017) on my 2016 target branch out from a common conceptual node like forks in a road. Calvo criticizes me for not acknowledging that plants too are likely to be sentient and claims I have fallen into the kind of category error of which I accuse others ─ a zoocentric bias that fails to grant consciousness to flora. Mallatt & Feinberg maintain that I've gone too far in granting sentience to any species that lacks a nervous system. Calvo makes some good points but there are other issues concerning plant sentience …

Machismo Predicts Prejudice Toward Lesbian And Gay Individuals: Testing A Mediating Role Of Contact, Michiyo Hirai, Serkan Dolma, Jason R. Popan, Mark H. Winkel

Psychological Science Faculty Publications

This study examined the relationship between traditional machismo and prejudice toward lesbian and gay individuals as mediated by contact in a Latino college sample. Gender was examined as a potential moderator. Undergraduate students from a public university in South Texas (128 males and 447 females; mean age = 22.1. SD = 4.75) completed online measures of prejudice toward lesbian and gay individuals, machismo, and contact experience with lesbian and gay individuals. Contact significantly mediated the relationship between machismo and anti-gay prejudice, yet this indirect effect was relatively small. Significant direct and indirect effects of machismo on prejudiced attitudes toward lesbian …

A Gender Invariant Model Of Disgust Propensity In Blood-Injection-Injury Phobia In Latina/O Individuals, Michiyo Hirai, Laura L. Vernon, Serkan Dolma

Psychological Science Faculty Publications

Latinas/os have been underrepresented in research investigating the role of disgust propensity in phobias. The current study was the first to examine associations between disgust propensity and Blood-Injection-Injury (BII) phobia, when acculturation was controlled for, in Latina/o Americans (n = 376). A structural model was developed with a BII fear latent variable consisting of fears of injection, blood, and sharp objects (causing injuries). The disgust propensity latent variable was formed with three domains of core, animal reminder, and contamination disgust elicitors. In the model, disgust propensity predicted BII fear when controlling for acculturation. A series of measurement and structural invariance …

Anthropocentrism As Cognitive Dissonance In Animal Research?, Ellen Furlong, Zachary Silver, Jack Furlong

Animal Sentience

Harmon-Jones et al. (2017) make a thought-provoking suggestion in their commentary on Zentall (2016): Overlooked biases among researchers on animal cognition might lead them to discount the traces of higher-order cognition in animals they study. We find the suggestion both philosophically important and worth further reflection for animal scientists. Harmon-Jones et al. point to two “cognitive dissonance” biases involving the clash between the common human resistance to viewing ourselves as animals/meat-eaters and how these biases might lead to discounting possible advanced cognitive performances in the animals studied. We show how these biases might appear in cognitive research generally and argue …
