The Effect Of Teaching Attending To A Face On Joint Attention Skills In Children With An Autism Spectrum Disorder, Tina Rovito Gomez

Dissertations, Theses, and Capstone Projects

Autism spectrum disorders are characterized in terms of behavioral deficits in areas of social behavior and language development. A failure to attend to the faces of others is the single best discriminator between 1-year-old children later diagnosed with an autism spectrum disorder (ASD) and those with typical development. Attending to the face of another provides the opportunity for episodes of attention sharing and is important to the development of communication, joint attention, and social behavior. A more advanced form of attending to a face is joint attention which has been defined as the ability to coordinate attention between an object …

Semi-Supervised Learning For Connectionist Networks, Rebecca Robare

Dissertations, Theses, and Capstone Projects

At the computational level, language is often assumed to require both supervised and unsupervised learning. Although we have a certain understanding of these computational processes both biologically and behaviorally, our understanding of the environmental conditions under which language learning takes place falls short. I examine the semi-supervised learning paradigm as the most accurate computational description of the environmental conditions of lexical acquisition during language development. This paradigm is assessed for task learning and generalization and I argue that its real ecological validity and occasional improvements in performance over supervised learning make it an ideal candidate for modeling of language acquisition …

Children's Tolerance Of Word-Form Variation, Paul Reeves Breuning

Dissertations, Theses, and Capstone Projects

This study compared children's (N=96, mean age 4;1, range 2;8-5;3) and adults' (N=96, mean age 21 years) tolerance of word-onset modifications (e.g., wabbit and warabbit) and pseudo affixes (e.g., kocat and catko) in a label extension task. Trials comprised an introductory phase where children saw a picture of an animal and were told its name, and a test phase where they were shown the same picture along with one of a different animal. For `similar-name' trials, participants heard a word-form modification of the previously introduced name (e.g., introduced to a dib, they were asked, `which animal is a wib?'). For …

Moderator Effects Of Working Memory On Symptom Stability In Attention-Deficit/Hyperactivity Disorder By Dopamine D1 And D2 Receptor Polymorphisms During Development, Joey W. Trampush

Dissertations, Theses, and Capstone Projects

Background: Developmental changes in dopaminergic pathways in the prefrontal cortex (PFC) that are important for working memory have been hypothesized to play a central role in the trajectory of attention-deficit/hyperactivity disorder (ADHD), but not the initial onset of the disorder. This dissertation research examines whether dopamine receptor D1 (DRD1) and dopamine receptor D2 (DRD2) gene polymorphisms moderate the association between improvements in working memory and declines in attention problems in ADHD from childhood to adolescence/young adulthood. Methods: Participants were 76 racially/ethnically diverse youth diagnosed with ADHD in childhood and followed prospectively for almost 10 years. Stability of ADHD symptomatology …

Testing The Relationship Between Body Dysmorphic Disorder And Pathological Skin Picking Using A Bidimensional Model Of ‘Fear’ And ‘Anger', Nicole Christine Egan

Dissertations and Theses @ UNI

Body image concerns are pervasive throughout Western culture, but there is a subset of the population who become so preoccupied with specific aspects of their appearance that it leads to clinically significant distress and impairment in their daily lives. This study examined symptoms of two disorders dealing with body concerns: Body Dysmorphic Disorder (BDD) and Pathological Skin Picking (PSP). The primary purpose of this study was to use the bidimensional model of 'fear' and 'anger' (Lara et al., 2006) to test the relationship between BOD & PSP. The model suggests that BDD and PSP are both characterized by high 'anger' …

Consequences Of Work-Family Balance And Comparisons With Work-Family And Family-Work Conflict, Sasha Marie Burnett

Dissertations and Theses @ UNI

The American work environment is quite different than it was just a few decades ago. Researchers, popular media, and employers alike have wondered how the changing labor environment is affecting employees. Participants in this study (N = 171) were 18 years of age or older, employed full-time and had at least one dependent child living at home. Of interest in this study was how well three measures of the work-family interface were able to predict five work-related consequences that would be of interest to employers. Work-family balance predicted both job satisfaction and intentions to quit, work-family conflict predicted job tension/strain …

Killing, Letting Die, And The Case For Mildly Punishing Bad Samaritanism, Ken M. Levy

Journal Articles

For over a century now, American scholars (among others) have been debating the merits of “bad-samaritan” laws – laws punishing people for failing to attempt “easy rescues.” Unfortunately, the opponents of bad-samaritan laws have mostly prevailed. In the United States, the “no-duty-to-rescue” rule dominates. Only four states even have bad-samaritan laws, and these laws impose only the most minimal punishment – either sub-$500 fines or short-term imprisonment.

This Article argues that this situation needs to be remedied. Every state should criminalize bad samaritanism. For, first, criminalization is required by the supreme value that we place on protecting human life, a …

We Call Ourselves By Many Names: Storytelling And Inter-Minority Coalition-Building, Celina Su

Publications and Research

Scholars debate whether new immigrants will join minority native-born groups, especially African-Americans, in battling racial disparities, income inequalities, and discrimination in the United States. Although scholars have investigated inter-minority coalition-building in the context of electoral politics, a substantial share of newer immigrant social and political action has not been formalized. Social change organizations play an integral role in less formalized politics. The article draws upon ethnographic data on two case study organizations to investigate how they built coalitions between immigrants and non-immigrants. It pinpoints the ways in which they engaged in storytelling to emphasize multiple identity – namely, how any …

“All The Men Here Have The Peter Pan Syndrome— They Don’T Want To Grow Up”: Navajo Adolescent Mothers’ Intimate Partner Relationships—A 15-Year Perspective, Rochelle L. Dalla, Alexandria M. Marchetti, Elizabeth (Beth) A. Sechrest, Jennifer L. White

Department of Child, Youth, and Family Studies: Faculty Publications

In 1992 and 1995, data were collected from 29 Navajo Native American adolescent mothers. In 2007 and 2008, data were collected from 21 of the original 29 (72%). Guided by feminist family theory, this investigation sought to (a) examine Navajo adolescent mothers’ intimate partner relationships during the transition to parenthood, (b) identify themes in the young mothers’ intimate partnerships across time, and (c) assess participants’ psychosocial well-being in adulthood. Four themes emerged in the women’s long-term intimate relationships: limited support, substance abuse, infidelity, and intimate partner violence. Implications of the findings and suggestions for future research are discussed.

A Conceptual Guide To Museum Visitors’ Understanding Of Evolution, E. Margaret Evans, Amy Spiegel, Wendy Gram, Brandy N. Frazier, Sarah Cover, Medha Tare, Judy Diamond

Department of Educational Psychology: Faculty Publications

Purpose: The purpose of this study was to profile natural history museum visitors’ reasoning about the evolution of seven organisms featured in Explore Evolution, an NSF funded exhibition. Seven current research studies on evolution were exhibited; each targeted different organisms: HIV, diatoms, ant/fungus, Hawaiian flies, Galapagos finches, humans/chimps, and fossilized whales. The exhibits illustrated a common set of evolutionary principles, variation, inheritance, selection, time, and adaptation, in diverse organisms.

Method: As part of the front-end evaluation, 32 museum visitors were interviewed and asked to explain evolutionary change in the seven organisms, though the term evolution was not mentioned. …

Depression Vulnerability Predicts Cigarette Smoking Among College Students: Gender And Negative Reinforcement Expectancies As Contributing Factors, Holly E.R. Morrell, Lee M. Cohen, Dennis E. Mcchargue

Department of Psychology: Faculty Publications

This study examined the association between vulnerability to depression and smoking behavior in college students in 1214 college students (54% female), and evaluated gender and expectancies of negative affect reduction as moderators or mediators of this relationship. Depression vulnerability predicted smoking in females, but not males. The relationship between depression vulnerability and smoking status was mediated by expectancies of negative affect reduction in females only. Female college students who are vulnerable to depression may smoke because they expect smoking to relieve negative affect. Smoking interventions for college females may increase in effectiveness by targeting depression and emphasizing mood regulation.

Confirmatory Factor Analysis Of The Child Feeding Questionnaire Among Low-Income African American Families Of Preschool Children, Richard E. Boles, Timothy D. Nelson, Leigh A. Chamberlin, Jessica M. Valenzuela, Susan N. Sherman, Susan L. Johnson, Scott W. Powers

Department of Psychology: Faculty Publications

This study examined the factor structure for three of the Child Feeding Questionnaire (CFQ) subscales, a widely used measure of parental feeding practices, among 296 low-income parents of African American preschool children. Confirmatory factor analysis showed an overall poor fit among CFQ subscales; Restriction, Pressure to Eat, and Concern about Child Weight, (χ2, (df = 87 = 300.249, CFI = 1.00, NNFI = 1.07, RMSEA = .091). Additionally, Cronbach’s Alpha coefficients for 2 of the three subscales were below acceptable recommendations (Restriction = 0.69; Pressure to Eat = 0.58). These results suggest further psychometric clarification is needed to understand commonly …

Examination Of The Construct Validity Of Impact™ Computerized Test, Traditional, And Experimental Neuropsychological Measures, Arthur C. Maerlender, L. Flashman, A. Kessler, S. Kumbhani, R. Greenwald, T. Tosteson, T. Mcallister

Department of Psychology: Faculty Publications

Although computerized neuropsychological screening is becoming a standard for sports concussion identification and management, convergent validity studies are limited. Such studies are important for several reasons: reference to established measures is needed to establish validity; examination of the computerized battery relative to a more traditional comprehensive battery will help understand the strengths and limitations of the computer battery; and such an examination will help inform the output of the computerized battery. We compared scores on the ImPACT™ battery to a comprehensive battery of traditional neuropsychological measures and several experimental measures used in the assessment of sports-related concussion in fifty-four healthy …

Cannabinoid Conditioned Reward And Aversion: Behavioral And Neural Processes, Jennifer E. Murray, Rick A. Bevins

Department of Psychology: Faculty Publications

The discovery that delta-9-tetrahydrocannabinol

(Δ⁹-THC) is the primary psychoactive ingredient in

marijuana prompted research that helped elucidate

the endogenous cannabinoid system of the brain.

Δ⁹-THC and other cannabinoid ligands with agonist

action (CP 55,940, HU210, and WIN 55,212-2)

increase firing of dopamine neurons and increase

synaptic dopamine in brain regions associated with

reward and drug addiction. Such changes in cellular

processes have prompted investigators to examine

the conditioned rewarding effects of the cannabinoid

ligands using the place conditioning task with rats and

mice. As reviewed here, these cannabinoid ligands

can condition place preferences (evidence for rewarding …

Reference Place Conditioning Procedure With Cocaine: Increased Sensitivity For Measuring Associatively Motivated Choice Behavior In Rats, Carmela M. Reichel, Jamie L. Wilkinson, Rick A. Bevins

Department of Psychology: Faculty Publications

Place conditioning is widely used to study the conditioned rewarding effects of drugs. In the standard version, one reward (cocaine) is compared to no reward (saline). A modified variant of this task, “reference-conditioning” procedure, compares two potentially rewarding stimuli (high versus low cocaine dose). There has been little research on the utility of this procedure. Experiment 1 used the standard protocol with saline administered before confinement to the reference compartment of a place-conditioning chamber. On alternating days, saline, 2.5, 5, 7.5, 10, or 20 mg/kg cocaine was administered before confinement to the opposite compartment. In Experiments 2 and 3, reference-compartment …

An Investigation Of Bupropion Substitution For The Interoceptive Stimulus Effects Of Nicotine, Jamie L. Wilkinson, F. Ivy Carroll, Rick A. Bevins

Department of Psychology: Faculty Publications

smoking cessation aid has not been fully elucidated, studies have found that bupropion and nicotine share behavioral and neurophysiological properties suggesting that bupropion might serve as a substitute for nicotine. In fact, bupropion prompts nicotine-appropriate responding in operant and Pavlovian drug discrimination studies with rats. A majority of the literature examining this substitution pattern has been done with an operant paradigm. The present research extended this literature by further characterizing the behavioral and neuropharmacological properties underlying the substitution for a nicotine conditioned stimulus (CS). Examination of the dose-effect function and temporal dynamics of this substitution pattern showed that bupropion (20 …

Extinction With Varenicline And Nornicotine, But Not Abt-418, Weakens Conditioned Responding Evoked By The Interoceptive Stimulus Effects Of Nicotine, Carmela M. Reichel, Jennifer E. Murray, Jessica D. Barr, Rick A. Bevins

Department of Psychology: Faculty Publications

The interoceptive stimulus effects of nicotine acquire control over behavior. This observation, among others, suggests that the stimulus effects of nicotine are important in the development and tenacity of tobacco dependence. Despite this importance, there has been little research examining whether non-reinforced presentations (extinction) of a ligand that share stimulus effects of nicotine will weaken responding controlled by nicotine. Rats were trained to discriminate nicotine (0.4 mg/kg) from saline using a discriminated goal-tracking task in which nicotine signaled intermittent access to sucrose; sucrose was withheld on saline sessions. Experiment 1 examined substitution for nicotine by ABT-418, nornicotine, epibatidine, varenicline, or …

A Phenomenological Inquiry Of Chronic Homeless Individuals' Challenges To Independence, Dewana Hall

Walden Dissertations and Doctoral Studies

Homelessness is a comprehensive social problem affecting approximately 744,000 people in the U.S. Despite consistent efforts from politicians, state and local leaders, and service providers, the number of homeless people continues to rise. Although there are some explanations in the literature to account for the increase of homelessness, the literature tends to not include the voices of the homeless themselves. The purpose of this phenomenological study, which used Maslow's hierarchy of needs as its conceptual framework, was to understand the life experiences of members of the homeless population, as perceived by four male residents of a mission in an eastern …

The Relationship Between Psychological Well-Being And Perceived Wellness In Graduate-Level Counseling Students, Michel Renee Harris

Walden Dissertations and Doctoral Studies

It is imperative that those who provide personal therapy to others be well-adjusted in their personal and professional lives and possess a keen and accurate perception of wellness. Yet, persons drawn to careers in counseling often have unresolved psychological issues. Counselor education programs should have a systematic way to evaluate and improve wellness in their students. Studies addressing the well-being of counselors-in-training, their perception of wellness, and their need for self-care are lacking in the professional literature. This study, therefore, examined the relationship between psychological well-being and perceived wellness in a sample (N = 97) of graduate students in a …

Illness Uncertainty, Ways Of Coping, And Psychological Adjustment Among 18--25-Year-Olds With Anaphylactic Food Allergy, Susan J. Cohen

Walden Dissertations and Doctoral Studies

The prevalence of food allergy is increasing, with adolescents and young adults being the group most likely to die from food-induced anaphylaxis. Behavioral and psychological factors contribute to this risk. This study investigated the relationship between illness uncertainty (as measured by the Mishel Uncertainty in Illness Scale Community Form) and emotion- and problem-focused coping (as measured by the Ways of Coping Scale), to see if they contributed to psychological adjustment (as measured by the Depression Anxiety Stress Scale-21) in this population. A cognitive diathesis-stress model was used to explain individual differences in adjustment. Multiple regression was used to test illness …

The Relationships Between Perceived Therapeutic Alliance, Therapist Self-Disclosure, And Dropout Expectancy Among Male Substance Abuse Treatment Participants, Harriett Elizabeth Reeh

Walden Dissertations and Doctoral Studies

There are contrasting views from Freudian, humanistic, and feminist theorists regarding whether therapist self-disclosure (TSD) affects the relationship between the therapeutic alliance (TA) and dropout of substance abuse treatment by males. However, there is a paucity of research regarding these topics yet therapists need clear empirical support for the use of TSD in enhancing the TA such that dropout can be averted. This study investigated whether or not TSD moderated the relationship between perceived TA and dropout expectancy. The research participants were 132 men attending residential substance abuse treatment. Four groups of men were randomly assigned to 1 of 4 …

Feasibility Of Brief Hospital-Based Interventions For Postpartum Depression : Effects On Depressive Symptoms, Perceived Support, & Treatment Utilization, Sabra N. Abboud

PCOM Psychology Dissertations

It is estimated that 10-20% of childbearing women develop postpartum depression (PPD), affecting up to 400,000 women in the United States each year. As many an 82% of women diagnosed with PPD decline recommended treatment, primarily due to a lack of knowledge about PPD, to societal stigma and to practical barriers. The objective of this study is to evaluate the feasibility of conducting a large-scale study examining the impact of screening measures and a supportive approach immediately postpartum on utilization of recommended care, levels of depression and perceived social support. Women were randomly assigned (N=40) on a maternity unit to …

A Comprehensive Investigation Of Variables Related To Children's Self-Perceptions, Renee Payton Cahill

PCOM Psychology Dissertations

In recent decades much has been revealed regarding children’s self-perceptions and sense of worth. Children engage in social comparisons to gauge their strengths and weaknesses relative to those around them. Thus one’s environment plays a critical role impacting one’s perceptions of self. Other variables suggested as contributing to children’s formulation of self-worth, include academic achievement, perception of victimization by peers, and academic placement. However, findings have been inconsistent in regard to the extent to which these variables relate to self-worth. The present study sought to discern if these variables relate to children’s self-perceptions. Results revealed a positive correlation between students’ …

Extension Of The Theory Of Planned Behaviour Incorporating An Improved Measure Of Emotion: An Application To Speeding, Chloe Jones

Theses : Honours

Speeding is related to crashes. The motivational factors underlying speeding must be identified to inform road safety. The Theory of Planned Behaviour (TPB) suggests that behavioural intention is predicted by attitude, subjective norm and perceived behavioural control. The present research was an attempted extension of the Theory of Planned Behaviour (TPB), in a speeding context. It was identified that the scales used in the TPB are not appropriately capturing emotion, and that the lack of emotion measures may be responsible for unaccounted for variance in intention. Questionnaires were developed based on Ajzen's (2006) and Bradley and Lang's (1999) methods. It …

The Experience Of Single Mothers: Resilience In Their Multiple Roles, Sharon Cheeseman

Theses : Honours

Single motherhood has been identified as a challenging role, with disadvantages including financial hardship and poor mental health. Resilience is a multidimensional construct, where two conditions need to occur: some form of adversity and positive adaptation. Resilience may empower single mothers to face the challenges whilst leading psychologically healthy and productive lives. Participants in this qualitative research study were ten West Australian single mothers, aged 35 to 45 years. A phenomenological methodology was used to understand their experiences with information collected through in-depth interviews and the Resilience Scale for Adults, used to complement the qualitative findings as descriptive support. Qualitative …

Lives In Transition: Ethnic Identity And Psychological Well-Being In Adults With A Highly Mobile Global Upbringing, Sutharshini (Dharshi) V. Vasikaran

Theses : Honours

This study explored the nature of ethnic identity and its relationship to psychological wellbeing (PWB) in third culture kids (TCKs). Ethnic identity achievement in acculturating individuals (e.g., migrants) is known to furnish one with a sense of belonging to one's group together with desirable psychological outcomes. Ethnic identity construction can be more complex in TCKs because of exposure to multiple cultural contexts during developmental years. Seven TCKs currently residing in Australia were interviewed. Analysis proceeded according to Ricoeur's hermeneutic phenomenology. Two themes were elucidated: 'Making sense of identity' and 'sense of belonging and PWB'. Single and multiple (blended and alternating) …

Terrorism In Australia: Myth Or Reality? A Psychometric Study Into The Western Australian Public's Perception Of Terrorism, Richard Sargent

Theses : Honours

Terrorism is not a new concept as terrorist individuals and organisations since time immemorial have used the threat of violence or actual violence to generate fear in individuals, organisations and governments alike. Fear is a powerful weapon and it is used in order to gain political, ideological or religious objectives. The attacks on the World Trade Centre and the Pentagon on the 11th September 2001 (9/11) highlighted the dangers of the inadequate intelligence, border security and immigration practices that led to this event. The attacks were a security wake up call not only for the United States of America but …

The Role Of Social Support Systems In Reducing Loneliness And Social Isolation For Parents Whose Partner Work Fly-In/Fly-Out, Nicole Fresle

Theses : Honours

Fly-in/fly-out (FIFO) practices in the mining and contracting industries are currently prominent and expanding throughout Western Australia. There is a strong need for effective social support systems for families during the worker's deployment due to long periods of time apart, reappraisal of family roles and social isolation. This study used a hermeneutic phenomenological approach to explore the lived experiences of parents whose partners are employed on a fly-in/fly-out basis and their views of social support systems in addressing the issues of loneliness and isolation. Family resilience was also utilised to investigate how female home-based partners deal with the stress involved …

Public Opinion On The Sentencing Of Mentally Ill Female Offenders; Factors That Influence People's Perceptions Of Appropriate Punishments And The Impact Of Personal Experience On Sentencing Judgements, Claire Adams

Theses : Honours

The aim of the current study was to explore public opinion on mentally ill female offenders in Western Australia, and the influence of these views on sentencing decisions. This study aimed to determine whether the mental health of a female offender influenced how people view a crime and the punishment they consider most appropriate for an offender. In addition, it aimed to investigate whether knowing someone with a mental illness influences people's perception of a crime and the sentencing decisions favoured for a mentally ill female offender. The study involved a between-subjects design comprising 118 participants, who received one version …
