Temporal Information Processing Across Primary Visual Cortical Layers In Normal And Red Light Reared Tree Shrews., Wenhao Dang

Electronic Theses and Dissertations

Visual neuroscience research has benefitted from decades of efforts of comparative studies of different species, since exploring and understanding the diversity of functional properties of visual system in different species has helped us identify both general organization rules and unique traits of certain species. In this study, spatio-temporal receptive fields (STRFs), together with some other functional properties (etc. stimulus preference to different visual stimuli, orientation tuning, temporal frequency tuning and the F1/F0 ratio of responses to sine-wave grating stimuli), of primary visual cortex (V1) cells were measured in normally reared and red-light reared tree shrews (Tupaia), a species considered the …

Awareness Of Executive Functioning As A Diagnostic Tool For Mild Cognitive Impairment And Alzheimer's Disease., Jeremy Stark Carmasin

Electronic Theses and Dissertations

This study examined the utility of older adults’ awareness of their executive functioning abilities to predict future cognitive decline. The recently revised Cognitive Awareness Model (CAM) forms the conceptual background of this approach, and suggests that executive dysfunction disrupts awareness in a manner distinct from episodic memory dysfunction. The study design examined how awareness of executive functioning ability may predict both continuous decline on neuropsychological testing and qualitative change in diagnostic status. This form of prediction was tested using a longitudinal sample (n = 661) of older adults with either normal cognition, mild cognitive impairment (MCI), or Alzheimer’s disease (AD). …

Objectification Theory And Eating Pathology In Latina College Students: Testing A Culture-Specific Model, Kimberly Claudat

UNLV Theses, Dissertations, Professional Papers, and Capstones

To date, sociocultural risk factors for eating disorder development in Latina women are poorly understood. Objectification theory provides a useful framework for understanding how sociocultural and intrapsychic variables influence eating pathology in women. However, few studies apply an objectification theory framework to the study of disordered eating in Latina women and even fewer studies examine the influence of culture-specific variables, such as acculturative stress and marianismo beliefs. Consequently, to address limitations in extant research, the present study applied the tenets of objectification theory to the study of eating pathology in Latina women using a culture-specific model. Specifically, this study investigated …

Pedagogical Approaches To Multicultural Education Within Teacher Preparation Programs, Mark Steven Barajas

Dissertations

Despite national standards established in 1979, U.S. teacher preparation programs have struggled to incorporate comprehensive, multicultural teacher education into existing curriculum (Sleeter, 2008). The weakness of multicultural training in most teacher preparation programs is theorized as a major contributor to the persistent achievement gap between students of color and White students (Ferguson, 2003). Furthermore, literature indicates White teachers frequently hold lower expectations for racial and ethnic minority students compared to White students and these lowered expectations often manifest as lower academic achievement (McKown & Weinstein, 2007).

This study provides empirical data regarding multicultural education within teacher preparation programs. Individual course …

The Effects Of Cosmopolitan Culture, Competitiveness, And Need For Cognitive Closure On Creativity, Chi-Ying Cheng

Research Collection School of Social Sciences

Deviant from thecurrent literature of multiculturalism-creativity link, this paper investigateswhether individuals benefit from exposure to one but diverse culture as well asthe moderators for this relationship. Drawing upon knowledge activation theory, Study 1found that individuals raised in a diverse culture like Singapore exhibithigher creativity when primed with their culture than in the control conditions. However, this advantage disappearswhen the Singaporean cultural tendency “Kiasu”, also known as extremecompetitiveness, is recalled when individuals are primed with their culture.Study 2 further examined how the Kiasu prime, personal Kiasu tendency, and needfor cognitive closure (NFCC) interact to influence creativity. The resultsshowed that when the …

Putting Singapore Above Self, David Chan

Research Collection School of Social Sciences

In an invited commentary published on the eve of Singapore's 50th year of independence, SMU Behavioural Sciences Institute director Professor David Chan discussed the need to guard against our own human self-serving tendencies in order to truly put Singapore above self. He explained the psychology of the self and how human self-serving tendencies can be overcome by being aware of them and cultivating positive attitudes.

Anger Rumination, Stress, And Dangerous Driving Behaviors As Mediators Of The Relationship Between Multiple Dimensions Of Forgiveness And Adverse Driving Outcomes, David J. Bumgarner

Electronic Theses and Dissertations

Motor-Vehicle crashes are the leading cause of death for teens and young adults. Research and public interventions have primarily examined the impact of external factors related to driving; however, less work has examined internal factors. Limited research has shown a negative association between trait forgiveness of others and both driving anger and driving aggression. The current study replicates previous findings and expands to include multiple dimensions of forgiveness and adverse driving outcomes as a dependent variable. It was predicted that multiple dimensions of forgiveness would be directly and indirectly related to adverse driving outcomes through the mediators of anger rumination, …

Self-Compassion And Self-Forgiveness As Mediated By Rumination, Shame-Proneness, And Experiential Avoidance: Implications For Mental And Physical Health, Elizabeth Conway Williams

Electronic Theses and Dissertations

Self-compassion and self-forgiveness appear to have much in common, as both relate to one’s self-regard during challenging circumstances; however, their empirical relationship is largely yet to be explored. The present study examines theoretical and empirical areas of overlap and proposes a theory of their relationship, including its possible impact on health. Self-compassion and self-forgiveness were proposed to have a direct relationship that may be mediated by reduction in rumination, shame, and experiential avoidance. These factors together were also hypothesized to have a positive impact on health functioning. The current study tested these models in a sample of undergraduate students (n …

Retroactive Interference In Recognition Memory: The Effects Of Mental Effort And Similarity On Recollection And Familiarity, Caleb Jordan Picker

UNLV Theses, Dissertations, Professional Papers, and Capstones

Learning new material may retroactively interfere with memory for older material. Retroactive interference research has typically focused on how similarity between old and new material affects recall of old material, which predicts greatest interference when similar material is presented just before test. However, mental effort may be another source of retroactive interference that could disrupt consolidation: Mental effort could cause the most retroactive interference when presented just after study. In Experiment 1, participants engaged in tasks designed to induce mental effort (e.g., solving easy or difficult math problems) at various times between the study and test of an associative recognition …

Influencing Acceptability Of Parent Training Interventions Through Treatment Rationales, Trisha Chase

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Parent training is an effective intervention for parents of children with a variety of childhood disorders, and parents often view behavioral parent training as acceptable. Explanations and rationales for parent training are commonly provided at the beginning of treatment. However, there is little research regarding how rationales may influence acceptability. There is also limited information on whether fathers and mothers judge the acceptability of parent training differently. The purpose of this study was to determine whether changing the description of a behavioral parenting intervention influenced parents’ acceptability ratings and whether mothers and fathers differed in their ratings.

Participants viewed one …

Lifestyle Intervention In Emerging Adulthood: A Brief Acceptance-Based Behavioral Intervention With Young Adults, Spencer M. Richards

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Across the U.S., obesity and overweight represent a rapidly growing public health concern that have been associated with expensive and debilitating outcomes such as depression, cancers, diabetes, and other metabolic disorders, cardiovascular disease, and significant disruption in quality of life, in addition to the tremendous public health costs. The current study examined a brief, randomized-controlled trial of acceptance and commitment therapy (ACT) with overweight and obese young adults.

Study participants were randomly assigned to a 4-week experimental ACT group or an information control group, which received psychoeducational materials regarding lifestyle behaviors recommended by the Centers for Disease Control and Prevention …

Fifty Psychological And Psychiatric Terms To Avoid: A List Of Inaccurate, Misleading, Misused, Ambiguous, And Logically Confused Words And Phrases, Scott O. Lilienfeld, Katheryn C. Sauvigné, Steven J. Lynn, Robin L. Cautin, Robert D. Latzman, Irwin D. Waldman

Psychology Faculty Publications

The goal of this article is to promote clear thinking and clear writing among students and teachers of psychological science by curbing terminological misinformation and confusion. To this end, we present a provisional list of 50 commonly used terms in psychology, psychiatry, and allied fields that should be avoided, or at most used sparingly and with explicit caveats. We provide corrective information for students, instructors, and researchers regarding these terms, which we organize for expository purposes into five categories: inaccurate or misleading terms, frequently misused terms, ambiguous terms, oxymorons, and pleonasms. For each term, we (a) explain why it is …

Counselor Self-Efficacy: Relationship With Mindfulness And Self-Compassion, Sinead K. Unsworth

Theses and Dissertations

Mindfulness training has well-documented effects on psychological and physical health (Davis & Hayes, 2011). Recent findings suggest that mindfulness may be a predictor in counselor self-efficacy (Bentley, 2008; Greason & Cashwell, 2009; Kane, 2010). However, a review of literature indicates that this relationship, along with the mediating effects of self-compassion, have not been examined quantitatively with mental health providers-in-training. This study examined the predictive relationship between mindfulness and counselor self-efficacy and the potential mediating effects of self-compassion. A total of 213 mental health providers-in-training were surveyed to determine their levels of mindfulness, self-compassion, and counselor self-efficacy. Three scales were used …

Assessing The Boundary Conditions Of The Own-Age And Own-Race Perceptual Bias For Faces, Cynthia C. Flores

Arts & Sciences Graduate Student Theses and Dissertations

Our interactions with other people rely on our ability to perceive and distinguish faces based on snap decisions about their features. Past research has revealed that facial recognition is consistently better when the observer shares the same race as the person being identified or is roughly in the same age category (Meissner & Brigham, 2001; Rhodes & Anastasi, 2012). Although a misidentification can be irritating in daily life, high discriminability is especially important in situations where a misidentification could have drastic consequences, such as in eye witness testimony or during security checkpoints conducted by law enforcement. Although much research has …

Web-Based Training For An Evidence-Supported Treatment: Training Completion And Knowledge Acquisition In A Global Sample Of Learners, Nicholas C. Heck, Benjamin E. Saunders, Daniel W. Smith

Psychology Faculty Research and Publications

The purpose of this investigation is to describe the characteristics of professional and preprofessional learners who registered for and completed TF-CBTWeb, a modular, web-based training program designed to promote the dissemination of Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) and to demonstrate the feasibility of this method of dissemination. Between October 1, 2005, and October 1, 2012, a total of 123,848 learners registered for TF-CBTWeb, of whom 98,646 (79.7%) initiated the learning activities by beginning the first module pretest. Of those, 67,201 (68.1%) completed the full training. Registrants hailed from 130 countries worldwide, and they had varied educational backgrounds, professional identities (both …

How Do Depression Medications Taken By Pilots Affect Passengers' Willingness To Fly? A Mediation Analysis, Stephen Rice, Scott R. Winter, Keegan Kraemer, Rian Mehta, Korhan Oyman

Publications

The mental health of airline pilots has been a concern for decades. In 2010, the United States Federal Aviation Administration began allowing four types of selective serotonin reuptake inhibitors (SSRIs) to be used by pilots suffering from depression. After a procedural wait period, pilots may be awarded a special issuance of their medical certificates to maintain flight currency. Missing from the literature was any research on consumer’s perceptions of pilots taking antidepressants, along with some other approved medications. Therefore, the purpose of the current study was to examine consumer’s willingness to fly once told that the pilot of their hypothetical …

An Exploratory Investigation Of Daycare Teacher Stress And Locus Of Control, Veronica Schumann

Theses and Dissertations

This study's purpose was to examine stress and locus of control in daycare teachers. A literature review was conducted to explore the various aspects of daycare services in America. The factors of locus of control and stress were signified and investigated as separate entities. The interaction between the two factors was also explored. In order to explore these two factors, a survey was administered to 19 daycare teachers from two different facilities. The presentation of both internal and external locus of control was expressed in approximately 70 percent of the teachers who were surveyed. A mild level of stress was …

Medication Non-Adherence In Community Dwelling Older Adults With Dementia: An Educational Intervention For Family Caregivers, Nika Renee George

Dissertations

Older adults with neurocognitive disorders are at high risk for medication non-adherence, while being vulnerable to great injury from regimen deviations. Informal caregivers often aid in healthcare management for these individuals. The current study compared the efficacy of two online health education interventions designed to increase caregiver health related knowledge for use with care recipients. Women (N=35) assisting a cognitively impaired older person with medications were randomly assigned to one of two online health education conditions (1) written materials and narrative vignettes depicting actors encountering common medication challenges or (2) written materials and didactic video clips of information from medical …

Decision Making And Association In Hoarding, Brianna Dora Mann

Dissertations

Hoarding is a serious and debilitating disorder that has a chronic course, is difficult to treat, and has a high treatment dropout rate. The most notable feature of hoarding is excessive clutter, which is driven by excessive acquiring of objects and difficulty discarding them. Two little researched factors that appear to be particularly central in contributing to acquiring and difficulty discarding are decision-making deficits and association. This study examined decision making and association, using self-report measures, a computerized decision-making task, and an association task, in a sample of 62 participants, consisting of 39 hoarders and 23 non-hoarding controls. These individuals …

Neural Correlates Of Rumination In Posttraumatic Stress Disorder Before And After Cognitive Processing Therapy, Katherine Ruth Buchholz

Dissertations

The utilization of functional magnetic resonance imaging (fMRI) techniques to examine biomarkers and neural activity patterns related to posttraumatic stress disorder (PTSD) has provided a way to investigate mechanisms that underlie the development, maintenance, and recovery from PTSD. Studying the neural correlates of individual differences related to transdiagnostic factors has the potential to provide clinically relevant information beyond that of diagnostic categories. Rumination is one such factor. Rumination, defined as repetitive, negative, self-focused thinking is considered to be a transdiagnostic factor that is associated with depression, anxiety, and PTSD. In individuals with PTSD, rumination serves as a cognitive avoidance factor …

Inversion Effects Reveal Dissociations In Facial Expression Of Emotion, Gender, And Object Processing, Pamela M. Pallett, Ming Meng

Dartmouth Scholarship

To distinguish between high-level visual processing mechanisms, the degree to which holistic processing is involved in facial identity, facial expression, and object perception is often examined through measuring inversion effects. However, participants may be biased by different experimental paradigms to use more or less holistic processing. Here we take a novel psychophysical approach to directly compare human face and object processing in the same experiment, with face processing broken into two categories: variant properties and invariant properties as they were tested using facial expressions of emotion and gender, respectively. Specifically, participants completed two different perceptual discrimination tasks. One involved making …

The Role Of Element Type And Crossed Relation In Restructuring Difficulty, Zhonglu Zhang, Ke Yang, Christopher M. Warren, Guang Zhao, Peng Li, Yi Lei, Hong Li

Psychology Faculty Publications

Chunk decomposition is an aspect of problem solving that involves decomposing a pattern into its component parts in order to regroup them into a new pattern. Previous work suggests that the primary source of difficulty in chunk decomposition is whether a problem’s solution requires removing a part that is a meaningful perceptual pattern (termed a chunk) or not (a non-chunk). However, the role of spatial overlap (crossed relation or not) has been ignored in this line of research. Here, we dissociated the role of element type and crossed relation in chunk decomposition problems by employing a Chinese character transformation task. …

Halting The Hallmarks: A Cellular Automaton Model Of Early Cancer Growth Inhibition, Jenna Butler, Frances Mackay, Colin Denniston, Mark Daley

Brain and Mind Institute Researchers' Publications

Cancer treatment is a fragmented and varied process, as ‘‘cancer’’ is really hundreds of different diseases. The ‘‘hallmarks of cancer’’ proposed by Hanahan and Weinberg (Cell 100(1):57–70, 2000) are a framework for viewing cancer within a common set of underlying principles—ten properties that are common to almost all cancers, allowing them to grow uncontrollably and ravage the body. We used a cellular automaton model of tumour growth paired with lattice Boltzmann methods modelling oxygen flow to simulate combination drugs targeted at knocking out pairs of hallmarks. We found that knocking out some pairs of cancer-enabling hallmarks did not prevent tumour …

The Association Of Different Types Of Bullying With The Mental Health Of Children And Teens From The United States, France, And Canada, Christina Fisher

Media and Communication Studies Summer Fellows

Bullying continues to trouble youths around the world, sometimes with devastating effects for victims’ mental health. This suggests an ongoing need for awareness, intervention and tolerance for everyone involved. This study, a literature review, explored the extent of these mental health effects found in 50 studies of victims, bullies, and bully-victims, those who are victims of bullying and who also bully others, in the United States, France, and Canada (Willard, 2007). Particular attention was paid to the impact that gender, age, ethnicity, and the LGBTQ community had on researchers’ findings. Findings show that 25.9% to 33% of students in these …

Decriminalizing Mental Illness: The Need For Treatment Over Incarceration Before Prisons Become The New Asylums For The Mentally Ill, Rebecca L. Brown

Psychology Summer Fellows

Currently, US prisons are home to 10 times more mentally ill individuals than state psychiatric hospitals. Instead of treating those with mental illness, an extremely vulnerable population is being thrown behind bars. Mental illness is often exacerbated during incarceration, leaving inmates much sicker than when they entered. Moreover, upon discharge mentally ill inmates have virtually no support, making recidivism almost inevitable. This lack of treatment has devastating consequences for the mentally ill as well as the community at large. Removing the mentally ill from jails and prisons would reduce recidivism, increase public safety and save money.

The current research explores …

Impaired Executive Function In Concussed Athletes, Marisa Gretz

Neuroscience Summer Fellows

Concussions are classified as mild traumatic brain injuries (mTBI). An individual that has sustained a concussion will experience symptoms such as nausea, possible memory loss, blurry vision, or loss of balance. Most symptoms subside within a few days, but a large pool of research raises concern for the recovery of executive function, specifically impulse control. Executive function relates to all tasks that require deliberate attention. Past research has shown adolescents record the highest number of sports concussions when compared to collegiate and professional athletes. The frontal lobe, which controls executive function, is not fully developed during the time of adolescence. …

How Does “Collaboration” Occur At All? Remarks On Epistemological Issues Related To Understanding / Working With ‘The Other’, Don Faust, Judith Puncochar

Conference Presentations

Collaboration, if to occur successfully at all, needs to be based on careful representation and communication of each stakeholder’s knowledge. In this paper, we investigate, from a foundational logical and epistemological point of view, how such representation and communication can be accomplished. What we tentatively conclude, based on a careful delineation of the logical technicalities necessarily involved in such representation and communication, is that a complete representation is not possible. This inference, if correct, is of course rather discouraging with regard to what we can hope to achieve in the knowledge representations that we bring to our collaborations. We suggest …
