Is Navigation In Virtual Reality With Fmri Really Navigation?, J.S. Taube, S. Valerio, Ryan M. Yoder Jan 2013

Is Navigation In Virtual Reality With Fmri Really Navigation?, J.S. Taube, S. Valerio, Ryan M. Yoder

Psychology

Identifying the neural mechanisms underlying spatial orientation and navigation has long posed a challenge for researchers. Multiple approaches incorporating a variety of techniques and animal models have been used to address this issue. More recently, virtual navigation has become a popular tool for understanding navigational processes. Although combining this technique with functional imaging can provide important information on many aspects of spatial navigation, it is important to recognize some of the limitations these techniques have for gaining a complete understanding of the neural mechanisms of navigation. Foremost among these is that, when participants perform a virtual navigation task in a …

Distinct Effects Of Enriched Environment On Dopamine Clearance In Nucleus Accumbens Shell And Core Following Systemic Nicotine Administration, Jun Zhu, Michael T. Bardo, Linda P. Dwoskin

Psychology Faculty Publications

Environmental enrichment during development may reduce drug abuse liability by modulating dopamine transporter (DAT) function. Nucleus accumbens (NAc) shell and core respond differentially to regulate the rewarding properties and locomotor stimulant effects of psychostimulants. The current study evaluated dopamine (DA) clearance (CLDA) in the NAc shell and core using in vivo voltammetry in rats raised in an enriched condition (EC) or an impoverished condition (IC) and determined the effect of nicotine (0.4 mg/kg) on CLDA. Baseline CLDA in NAc shell and core was not different between EC and IC rats. In the saline control group, …

Furious Activity Vs. Understanding: How Much Expertise Is Needed To Evaluate Creative Work?, Learning Research Institute, John Baer, David H. Cropley, Roni Reiter-Palmon Jan 2013

Furious Activity Vs. Understanding: How Much Expertise Is Needed To Evaluate Creative Work?, Learning Research Institute, John Baer, David H. Cropley, Roni Reiter-Palmon

Psychology Faculty Publications

What is the role of expertise in evaluating creative products? Novices and experts do not assess creativity similarly, indicating domain-specific knowledge’s role in judging creativity. We describe two studies that examined how quasi-experts (people who have more experience in a domain than novices but also lack recognized standing as experts) compared to novices and experts in rating creative work. In Study One, we compared different types of quasi-experts with novices and experts in rating short stories. In Study Two, we compared experts, quasi-experts, and novices in evaluating an engineering product (a mousetrap design). Quasi-experts (regardless of type) seemed to be …

Youth Treatment Adherence At A Rural Community Mental-Health Clinic, Asma S. Ali

PCOM Psychology Dissertations

This study examined the relationships between youth and adult psychopathology, and sociodemographic factors and treatment adherence for youth attending outpatient treatment at a rural community mental-health clinic. “Adherence” was defined as attending more than five sessions, while “non-adherence” was defined as attending fewer than or equal to five sessions. Results revealed no significant differences between youth adhering or not adhering to treatment depending on the relation of caregiver to youth or the mode of transportation taken to the clinic. Furthermore, caregiver and youth psychopathology and caregiver’s estimated travel time to the clinic did not predict treatment adherence. Incidentally, examination of …

A Single Case Study Of Cognitive Remediation Therapy With An Adolescent With Disordered Eating, Carol Lynn Galiano Jan 2013

A Single Case Study Of Cognitive Remediation Therapy With An Adolescent With Disordered Eating, Carol Lynn Galiano

PCOM Psychology Dissertations

Picky eating is currently not included in the diagnostic classification system DSM-IV TR as a distinct category of eating disorders in childhood. It can reach clinical significance requiring intervention when it results in chronic nutritional inadequacies and/or harmful impact on social development or family functioning. Studies have shown that patients with eating disorders have difficulties with executive functioning. These findings have been used to develop an intervention based on cognitive remediation therapy (CRT) which targets thinking skills and their role in the development and maintenance of an eating disorder. To further investigate, this study assessed the efficacy of an 8-week, …

Associations Between Different Parenting Styles And Child Behavior, Jason C. Hunt Jan 2013

Associations Between Different Parenting Styles And Child Behavior, Jason C. Hunt

PCOM Psychology Dissertations

Attention-Deficit/Hyperactivity Disorder (ADHD) is a chronic, behavioral control disorder, which is most frequently diagnosed in children. ADHD is traditionally conceptualized as a neurological disorder; however, there are important environmental factors that affect symptom presentation. Parental involvement is a critical factor in virtually every form of treatment for ADHD, yet the specific parenting styles employed by parents of children with ADHD has received little attention. This study sought to address this issue through identifying associations between parenting styles, ADHD symptoms, and homework problems. Participants were recruited from a community sample, using a snowball sampling method. Participants were required to complete three …

Letter Of Purpose Of The Feminist Evolutionary Psychology Society, T. Joel Wade Jan 2013

Letter Of Purpose Of The Feminist Evolutionary Psychology Society, T. Joel Wade

Faculty Journal Articles

It has been almost five years since the formation of the Feminist Evolutionary Psychology Society (FEPS), which was created with the hopes of drawing attention to issues that influence women’s role in evolution. In those years, FEPS has changed into a more structured society with clear aims. In this letter, we review the rationale for creating FEPS, as well as how we structured FEPS to be an effective organization. The majority of the letter pertains to four distinct goals of FEPS that we will continue to address in the future. These goals are to investigate the active role of women …

The Interface Between Morphology And Action Planning: A Comparison Of Two Species Of New World Monkeys, Stacey L. Zander, Dan J. Weiss, Peter G. Judge Jan 2013

The Interface Between Morphology And Action Planning: A Comparison Of Two Species Of New World Monkeys, Stacey L. Zander, Dan J. Weiss, Peter G. Judge

Faculty Journal Articles

Recent research with several species of nonhuman primates suggests sophisticated motor-planning abilities observed in human adults may be ubiquitous among primates. However, there is considerable variability in the extent to which these abilities are expressed across primate species. In the present experiment, we explore whether the variability in the expression of anticipatory motor-planning abilities may be attributed to cognitive differences (such as tool use abilities) or whether they may be due to the consequences of morphological differences (such as being able to deploy a precision grasp). We compared two species of New World monkeys that differ in their tool use …

Friendship As A Relationship Infiltration Tactic During Human Mate Poaching., Justin Mogilski, T. Joel Wade

Faculty Journal Articles

Previous research has characterized human mate poaching as a prevalent alternative mating strategy that entails risks and costs typically not present during general romantic courtship and attraction. This study is the first to experimentally investigate friendship between a poacher and his/her target as a risk mitigation tactic. Participants (N = 382) read a vignette that differed by whether the poacher was male/female and whether the poacher and poached were friends/acquaintances. Participants assessed the likelihood of the poacher being successful and incurring costs. They also rated the poacher and poached on several personality and mate characteristics. Results revealed that friendship increased …

Mitigation Of Motion Sickness Symptoms In 360 Degree Indirect Vision Systems, Stephanie Quinn Jan 2013

Mitigation Of Motion Sickness Symptoms In 360 Degree Indirect Vision Systems, Stephanie Quinn

Electronic Theses and Dissertations

The present research attempted to use display design as a means to mitigate the occurrence and severity of symptoms of motion sickness and increase performance due to reduced “general effects” in an uncoupled motion environment. Specifically, several visual display manipulations of a 360° indirect vision system were implemented during a target detection task while participants were concurrently immersed in a motion simulator that mimicked off-road terrain which was completely separate from the target detection route. Results of a multiple regression analysis determined that the Dual Banners display incorporating an artificial horizon (i.e., AH Dual Banners) and perceived attentional control significantly …

Neurophenomenological Methods: Experiences Of Earth And Space In Simulation, Patricia Morrow

Electronic Theses and Dissertations

The present study explores the nature and structure of spiritual and aesthetic experiences through the interdisciplinary application of neurophenomenology (NP). This approach merges aspects of psychology, neurophysiology, and phenomenology into a unified methodology. The study is nested within a larger project, Space, Science, and Spirituality, and as such, it carries a common goal to use simulation to evoke spiritual and aesthetic responses similar to those expressed by astronauts and cosmonauts. Careful analysis of previous work in NP provided methodological “lessons learned”, which guided the experimental design, execution, and analysis of the present study. The data collected provides support for experience …

A Randomized Trial Of Attention Training For Generalized Social Phobia: Does Attention Training Change Social Behavior?, Brian Bunnell Jan 2013

A Randomized Trial Of Attention Training For Generalized Social Phobia: Does Attention Training Change Social Behavior?, Brian Bunnell

Electronic Theses and Dissertations

The use of attention training protocols for the treatment of generalized social anxiety disorder (SAD) is undergoing increased examination. Initial investigations were positive but more recent investigations have been less supportive of the treatment paradigm. One significant limitation of current investigations may be over-reliance on self-report. In this investigation, we expanded on initial investigations by using a multimodal assessment of patient functioning (i.e., including behavioral assessment). Patients with a primary diagnosis of SAD (n = 31) were randomly assigned to eight sessions of attention training (n = 15) or placebo/control (n = 16). Participants were assessed at pre- and post-treatment …

Measurement Of Negative Affectivity In Psychometrically Defined Schizotypy Using Facial Electromyography, Jonathan Mitchell Jan 2013

Measurement Of Negative Affectivity In Psychometrically Defined Schizotypy Using Facial Electromyography, Jonathan Mitchell

Electronic Theses and Dissertations

Schizotypy is a sub-threshold syndrome associated with schizophrenia. Much of the research on schizotypy concerns its component features, one of which being blunted or constricted affect. While several investigations have addressed this common “negative” symptom within the context of schizophrenia, few have focused on schizotypy directly, and none have utilized psychophysiological measurement to examine affective constriction. The present investigation uses facial electromyography (EMG) to measure patterns of affective expression within a psychometrically defined schizotypal population when presented threatening and distressing pictures from the IAPS. Twenty-eight individuals with elevated schizotypal features and 20 healthy controls were recruited for this investigation. The …

How Emoticons Affect Leader-Member Exchange, Jennifer Loglia Jan 2013

How Emoticons Affect Leader-Member Exchange, Jennifer Loglia

Electronic Theses and Dissertations

Emoticons have been shown to be the nonverbal cues of computer-mediated communication and could therefore be a rich source of information, but they are not used in the workplace because they are considered unprofessional. This study aimed to look at the effects of emoticons on relationships, specifically between a leader and member. Participants were asked to read a fake email from a fake boss and answer several questions in regard to leader-member exchange, affective presence, perceived message positivity, perceived masculinity/femininity of the fake boss, and perceived professionalism. This study found that the use of a positive emoticon in an email …

Daughters' Perception Of Parental Gender Disappointment In Relationship To Eating Disorders, Carolyn S. Bloye Jan 2013

Daughters' Perception Of Parental Gender Disappointment In Relationship To Eating Disorders, Carolyn S. Bloye

Doctor of Psychology (PsyD)

The impact of familial relationships, as both protective and risk factors, on the development and treatment of eating disorders (ED) is a frequent topic of research (Cordero & Israel, 2009 Enten & Golan, 2009). However, Parental Gender Disappointment (PGD) as related to ED is one family dynamic that has not been studied. PGD may occur when a child is not born the gender of their parent's prenatal preference and the negative impact it can have on the child has been demonstrated (Stattin, 1991). This study sought to examine the potential relationship between Perceived Parental Gender Disappointment (PPGD) and ED through …
