There is limited research on African-American college students and their participation in group psychotherapy in a university counseling center setting. This study examined the barriers to group psychotherapy for African-American college students. A 61 item survey was designed to obtain African-American college students' views on their willingness to participate in group therapy, expectations of group psychotherapy, expectations of group members, expectations of group leaders, coping skills when in distress, and multicultural considerations relating to group psychotherapy. Data collected from a sample (N = 108)was analyzed using descriptive statistics and regression analyses. Results of the this study found that coping strategies …


Predicting Premorbid Ability In African American Elders Using Demographic And Performance Variables, Hayley Kristinsson Jan 2012

Predicting Premorbid Ability In African American Elders Using Demographic And Performance Variables, Hayley Kristinsson

Browse all Theses and Dissertations

Researchers and clinicians require a method of estimating an elderly individual's premorbid ability level in order to determine the amount of cognitive decline that has occurred. This issue has received a great deal of attention within the research literature; however, little attention has been paid to this issue specifically in elderly African American elderly adults. Although researchers have examined the predictive utility of demographic variables, few studies have examined whether including additional demographic variables (i.e., quality of education) improves prediction of premorbid ability. The current sample consisted of 46 African American elderly adults who did not exhibit any cognitive impairment …


Minority Bias In Supervisor Ratings: Comparing Subjective Ratings And Objective Measures Of Job Performance, William Hernandez Jan 2012

Minority Bias In Supervisor Ratings: Comparing Subjective Ratings And Objective Measures Of Job Performance, William Hernandez

Browse all Theses and Dissertations

Supervisor ratings of job performance and objective sales performance were examined to better understand the causes of observed differences in performance ratings between Men and Women and Caucasians and African-Americans. Sex and race did not significantly predict subjective ratings of job performance. Ratee sex and race accounted for less than 2% of the variance in subjective ratings of ratee job performance. However, it was found that Women performed significantly lower than Men, but the difference disappeared when women comprised greater than 30% of the workforce, suggesting a real difference in performance. No tokenism effect was found for Women or racial …

Facebook: Shifting Privacy, Identity, And Power Online, Rachel Verni

Dissertations, Theses, and Capstone Projects

Due to staggering technological shifts in recent decades, the Internet has become a routine fixture in everyday life. The popularity of social networking sites, in particular, raises myriad questions regarding identity construction and social interaction. It is also unclear how these practices are related to perceptions of privacy. This dissertation examines how traditional notions of privacy compare, and apply, to privacy on the Internet and considers how issues of power are (re)created in online spaces. By focusing on identity enactment strategies and social connectivity practices, this work sheds light on the ways in which individuals define privacy and choose to …


Social Aspects Of Developing And Sustaining Voluntarily Reduced Consumption Activity In New York City, Kirsten B. Firminger Jan 2012

Social Aspects Of Developing And Sustaining Voluntarily Reduced Consumption Activity In New York City, Kirsten B. Firminger

Dissertations, Theses, and Capstone Projects

This dissertation examines the social aspects of voluntarily reduced consumption activity using the principles of cultural historical activity theory. Voluntarily buying less is viewed as ongoing interactive social process that is initiated and sustained as individuals engage with their surroundings. Data was collected from 320 online survey respondents living in the New York City Metro area, followed by a purposeful sampling of 24 participants for in-person, follow up interviews. Interviews revealed the social contextual influences on initiating voluntarily reduced consumption activity. For example, family experiences, personal life changes, and historical events played a role in individuals' choice to voluntarily buy …


Effects Of Childhood Family Dynamics On Body Dissatisfaction In Adulthood, Adrienne F. Kerbs Jan 2012

Effects Of Childhood Family Dynamics On Body Dissatisfaction In Adulthood, Adrienne F. Kerbs

EWU Masters Thesis Collection

"Past research has identified many singular components of family dynamics that affect body dissatisfaction in adulthood, but have not studied the effects of many different family factors simultaneously. The aim of the current study was to investigate the effects of multiple early family dynamics on body dissatisfaction in adulthood using a sample of female college students. It was expected that the nature of parental bonding, parental comments, and lack of parental acceptance during childhood would have negative effects on body image in adulthood. A sample of female college students completed self-report questionnaires about their parents from the perspective of when …

Examining Associations Between Classroom Environment And Processes And Early Mathematics Performance From Pre-Kindergarten To Kindergarten, Victoria J. Molfese, E. Todd Brown, Jill L. Adelson, Jennifer Beswick, Jill L. Jacobi-Vessels, Lana Thomas, Melissa Ferguson, Brittany Culver Jan 2012

Examining Associations Between Classroom Environment And Processes And Early Mathematics Performance From Pre-Kindergarten To Kindergarten, Victoria J. Molfese, E. Todd Brown, Jill L. Adelson, Jennifer Beswick, Jill L. Jacobi-Vessels, Lana Thomas, Melissa Ferguson, Brittany Culver

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

One benefit of the No Child Left Behind legislation (2001) has been the increasing attention on the importance of the skills learned in the pre-kindergarten period for later academic achievement (Denton & West, 2002; National Mathematics Advisory Panel, 2008; Whitehurst, 2001). There is a growing awareness that mathematics skills in kindergarten and beyond are influenced by the formal and informal mathematics skills acquired in the pre-kindergarten classroom. Indeed, policy makers, researchers, and educators are now arguing that pre-kindergarten mathematics instruction must be recognized as a critical factor affecting young children’s mathematics learning at school age (Ginsburg, Lee & Boyd, 2008). …


Science, Technology, Engineering, And Mathematics Graduate Teaching Assistants Teaching Self-Efficacy, Sue Ellen Dechenne, Larry G. Enochs, Mark Needham Jan 2012

Science, Technology, Engineering, And Mathematics Graduate Teaching Assistants Teaching Self-Efficacy, Sue Ellen Dechenne, Larry G. Enochs, Mark Needham

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

The graduate experience is a critical time for development of academic faculty, but often there is little preparation for teaching during the graduate career. Teaching self-efficacy, an instructor’s belief in his or her ability to teach students in a specific context, can help to predict teaching behavior and student achievement, and can be used as a measure of graduate students’ development as instructors. An instrument measuring teaching self-efficacy of science, technology, engineering, and mathematics (STEM) graduate teaching assistants (GTAs) was developed from a general university faculty teaching instrument to the specific teaching context of STEM GTAs. Construct and face validity, …

Department of Educational Psychology: Faculty Publications

Background: Cerebral white matter abnormalities on term MRI are a strong predictor of motor disability in children born very preterm. However, their contribution to cognitive impairment is less certain. Objective: Examine relationships between the presence and severity of cerebral white matter abnormalities on neonatal MRI and a range of neurocognitive outcomes assessed at ages 4 and 6 years. Design/Methods: The study sample consisted of a regionally representative cohort of 104 very preterm (≤32 weeks gestation) infants born from 1998–2000 and a comparison group of 107 full-term infants. At term equivalent, all preterm infants underwent a structural MRI scan that was …


Book Review: The Morality Of Social Identity, David Moshman Jan 2012

Book Review: The Morality Of Social Identity, David Moshman

Department of Educational Psychology: Faculty Publications

Morality tells us how to treat each other. Social identity connects us to each other. But all is not well. Social identity connects us to a group and thus to its members. Morality requires justice for everyone, regardless of group. Thus considerations of morality and social identity often pull in different directions (Appiah, 2005; Moshman, 2007; Sen, 2006).

Two excellent and complementary new books, Children and Social Exclusion and Narrative and the Politics of Identity, address the developmental roots and implications of these issues. The first reviews and integrates multiple programs of research on children’s developing judgments about dilemmas …

Lisa PytlikZillig Publications

Regular public input into a city's budget is frequently associated with municipal budgeting in Brazilian cities, successes in public engagement that have been emulated around the world. American communities are adopting the practice to varying degrees. This paper will report on a five-year old public input program that is taking place in Lincoln, Nebraska, the capital city of a politically conservative state in the U.S. We discuss the processes we use to engage the public about the City's budget. The process includes regular online input as well as face-to-face, deliberative discussions. On occasions, random sample surveys also have been used. …


Do Clark’S Nutcrackers Demonstrate What-Where-When Memory On A Cache-Recovery Task?, Kristy L. Gould, Amy J. Ort, Alan C. Kamil Jan 2012

Do Clark’S Nutcrackers Demonstrate What-Where-When Memory On A Cache-Recovery Task?, Kristy L. Gould, Amy J. Ort, Alan C. Kamil

Avian Cognition Papers

What-where-when (WWW) memory during cache recovery was investigated in six Clark’s nutcrackers. During caching, both red- and blue-colored pine seeds were cached by the birds in holes filled with sand. Either a short (3 day) retention interval (RI) or a long (9 day) RI was followed by a recovery session during which caches were replaced with either a single seed or wooden bead depending upon the color of the cache and length of the retention interval. Knowledge of what was in the cache (seed or bead), where it was located, and when the cache had been made (3 or 9 …


The Political Left Rolls With The Good And The Political Right Confronts The Bad: Connecting Physiology And Cognition To Preferences, Michael D. Dodd, Amanda Balzer, Carly M. Jacobs, Michael W. Gruszczynski, Kevin B. Smith, John R. Hibbing Jan 2012

The Political Left Rolls With The Good And The Political Right Confronts The Bad: Connecting Physiology And Cognition To Preferences, Michael D. Dodd, Amanda Balzer, Carly M. Jacobs, Michael W. Gruszczynski, Kevin B. Smith, John R. Hibbing

Department of Psychology: Faculty Publications

We report evidence that individual-level variation in people’s physiological and attentional responses to aversive and appetitive stimuli are correlated with broad political orientations. Specifically, we find that greater orientation to aversive stimuli tends to be associated with right-of-centre and greater orientation to appetitive (pleasing) stimuli with left-of-centre political inclinations. These findings are consistent with recent evidence that political views are connected to physiological predispositions but are unique in incorporating findings on variation in directed attention that make it possible to understand additional aspects of the link between the physiological and the political.


Contributions Of Dynamic Systems Theory To Cognitive Development, John P. Spencer, Andrew Austin, Anne R. Schutte Jan 2012

Contributions Of Dynamic Systems Theory To Cognitive Development, John P. Spencer, Andrew Austin, Anne R. Schutte

Department of Psychology: Faculty Publications

This paper examines the contributions of dynamic systems theory to the field of cognitive development, focusing on modeling using dynamic neural fields. A brief overview highlights the contributions of dynamic systems theory and the central concepts of dynamic field theory (DFT). We then probe empirical predictions and findings generated by DFT around two examples—the DFT of infant perseverative reaching that explains the Piagetian A-not-B error, and the DFT of spatial memory that explain changes in spatial cognition in early development. A systematic review of the literature around these examples reveals that computational modeling is having an impact on empirical research …

Association Between The Serotonin Transporter Triallelic Genotype And Eating Problems Is Moderated By The Experience Of Childhood Trauma In Women, Scott F. Stoltenberg, Cynthia Anderson, Parthasarathi Nag, Cheryl Anagnopoulos

Department of Psychology: Faculty Publications

Objective—This study investigated a potential interaction between the triallelic polymorphism of the serotonin transporter gene (SLC6A4) promoter and the experience of childhood trauma on the number of problem eating behaviors.

Methods—The study sample was comprised of 439 (64.7% female) Caucasian college students (mean age = 22.49, SD = 6.12). Participants completed questionnaires that assessed eating problems and experience of trauma in childhood (ages 0-12) and donated cheek cells for 5- HTTLPR and rs25531 genotyping.

Results—Women carrying a lower expressing allele (i.e. LG or S) who were exposed to higher levels of childhood trauma reported significantly higher mean numbers of eating …


Neural Mechanisms Underlying Neurooptometric Rehabilitation Following Traumatic Brain Injury, Caitlin M. Hudac, Srinivas Kota, James L. Nedrow, Dennis L. Molfese Jan 2012

Neural Mechanisms Underlying Neurooptometric Rehabilitation Following Traumatic Brain Injury, Caitlin M. Hudac, Srinivas Kota, James L. Nedrow, Dennis L. Molfese

Department of Psychology: Faculty Publications

Mild to severe traumatic brain injuries have lasting effects on everyday functioning. Issues relating to sensory problems are often overlooked or not addressed until well after the onset of the injury. In particular, vision problems related to ambient vision and the magnocellular pathway often result in posttrauma vision syndrome or visual midline shift syndrome. Symptoms from these syndromes are not restricted to the visual domain. Patients commonly experience proprioceptive, kinesthetic, vestibular, cognitive, and language problems. Neurooptometric rehabilitation often entails the use of corrective lenses, prisms, and binasal occlusion to accommodate the unstable magnocellular system. However, little is known regarding the …

Clinical Phd Graduate Student Views Of Their Scientist-Practitioner Training, Joseph W. Vanderveen, L Felice Reddy, Jennifer C. Veilleux, Alicia M. January, David Dilillo

Department of Psychology: Faculty Publications

Objectives: The goal of the scientist-practitioner (S-P) training model is to produce clinical psycholo-gists equipped to integrate and utilize both science and practice in the clinical and research domains. However, much has been written regarding the possible shortcomings of S-P training and whether clinical psychology graduate students are actually gaining the knowledge and skills to integrate sci-ence and practice during graduate training and beyond (Chang, Lee, & Hargreaves, 2008; Gelso, 2006; Merlo, Collins, & Bernstein, 2008; Phillips, 1993). Methods: As such, the present study assessed ratings of satisfaction, perception of ability, and use of the S-P training model within 653 …


Iptakalim Preferentially Decreases Nicotine-Induced Hyperlocomotion In Phencyclidine-Sensitized Rats: A Potential Dual Action Against Nicotine Addiction And Psychosis, Nick Volf, Gang Hu, Ming Li Jan 2012

Iptakalim Preferentially Decreases Nicotine-Induced Hyperlocomotion In Phencyclidine-Sensitized Rats: A Potential Dual Action Against Nicotine Addiction And Psychosis, Nick Volf, Gang Hu, Ming Li

Department of Psychology: Faculty Publications

Objective: Iptakalim is a putative ATP-sensitive potassium (KATP) channel opener. It is also a novel nicotinic acetylcholine receptor (nAChR) blocker and can antagonize nicotine-induced increase in dopamine release in the nucleus accumbens. Our recent work also shows that iptakalim exhibits a clozapine-like atypical antipsychotic profile, indicating that iptakalim may possess a dual action against nicotine addiction and schizophrenia.

Methods: The present study examined the potential therapeutic effects of iptakalim on nicotine use in schizophrenia. We created an animal model of comorbidity of nicotine addiction and schizophrenia by injecting male Sprague-Dawley rats with nicotine (0.40 mg/kg, subcutaneously[sc]) or saline, in combination …

Conditioned Response Evoked By Nicotine Conditioned Stimulus Preferentially Induces C-Fos Expression In Medial Regions Of Caudate-Putamen, Sergios Charntikov, Matthew E. Tracy, Changjiu Zhao, Ming Li, Rick A. Bevins

Department of Psychology: Faculty Publications

Nicotine has both unconditioned and conditioned stimulus properties. Conditioned stimulus properties of nicotine may contribute to the tenacity of nicotine addiction. The purpose of this experiment was to use neurohistochemical analysis of rapidly developing c-Fos protein to elucidate neurobiological loci involved in the processing of nicotine as an interoceptive conditioned stimulus (CS). Rats were injected (SC) in an intermixed fashion with saline or nicotine (16 sessions of each) and placed in conditioning chambers where they were given one of the three conditions depending on group assignment: (a) nicotine paired 100% of the time with intermittent access to sucrose (nicotine-CS condition), …


Differential Effects Of Acute Amphetamine And Phencyclidine Treatment And Withdrawal From Repeated Amphetamine Or Phencyclidine Treatment On Social Interaction And Social Memory In Rats, Ming Li, Wei He, Rebecca Munro Jan 2012

Differential Effects Of Acute Amphetamine And Phencyclidine Treatment And Withdrawal From Repeated Amphetamine Or Phencyclidine Treatment On Social Interaction And Social Memory In Rats, Ming Li, Wei He, Rebecca Munro

Department of Psychology: Faculty Publications

Although animal models based on amphetamine (AMPH) or phencyclidine (PCP) treatment have been used extensively to study the neurobiological and behavioral characteristics of schizophrenia, there are conflicting reports regarding their validity in modeling the negative symptoms and cognitive deficits of schizophrenia. The present study examined how acute AMPH or PCP treatment (Experiment 1) and withdrawal from repeated AMPH treatment (Experiment 2) or PCP treatment (Experiment 3) affects social behavior and social recognition memory in male Sprague-Dawley rats. Each subject was tested on two consecutive days. On the first day, the rats were tested four times (5 min/each) at 10-min intervals …

Rotational Head Kinematics In Football Impacts: An Injury Risk Function For Concussion, Steven Rowson, Stefan M. Duma, Jonathan G. Beckwith, Jeffrey J. Chu, Richard M. Greenwald, Joseph J. Crsico, P. Gunnar Brolinson, Ann-Christine Duhaime, Thomas W. Mcallister, Arthur C. Maerlender

Department of Psychology: Faculty Publications

Recent research has suggested a possible link between sports-related concussions and neurodegen-erative processes, highlighting the importance of developing methods to accurately quantify head impact tolerance. The use of kinematic parameters of the head to predict brain injury has been sug-gested because they are indicative of the inertial response of the brain. The objective of this study is to characterize the rotational kinematics of the head associated with concussive impacts using a large head acceleration dataset collected from human subjects. The helmets of 335 football players were instrumented with accelerometer arrays that measured head acceleration following head impacts sustained during play, …

Disentangling The Nature Of The Nicotine Stimulus, Rick A. Bevins, Scott T. Barrett, Robert J. Polewan, Steven T. Pittenger, Natashia Swalve, Sergios Charntikov

Department of Psychology: Faculty Publications

Learning involving interoceptive stimuli likely plays an important role in many diseases and psychopathologies. Within this area, there has been extensive research investigating the interoceptive stimulus effects of abused drugs. In this pursuit, behavioral pharmacologists have taken advantage of what is known about learning processes and adapted the techniques to investigate the behavioral and receptor mechanisms of drug stimuli. Of particular interest is the nicotine stimulus and the use of the two-lever operant drug discrimination task and the Pavlovian drug discriminated goal-tracking task. There is strong concordance between the two methods when using “standard” testing protocols that minimize learning on …

Discussion On The Paper By Neumann, Evett And Skerrett, Michael J. Saks, Ashley M. Votruba

Department of Psychology: Faculty Publications

Neumann, Evett, and Skerrett have made a major contribution to the art and science of fingerprint identification. This is an important—perhaps historic—step forward in the intellectual history of fingerprint identification and perhaps other fields of pattern matching forensic science. Their work deals ingeniously with the elusive problem of placing forensic identification on an empirically sound, quantitative foundation.
