Reversal Of Age-Associated Cognitive Deficits Is Accompanied By Increased Plasticity-Related Gene Expression After Chronic Antidepressant Administration In Middle-Aged Mice, Yan Li, Aicha Abdourahman, Joseph A. Tamm, Alan Pehrson, Connie Sánchez, Maria Gulinello

Department of Psychology Faculty Scholarship and Creative Works

Cognitive decline occurs during healthy aging, even in middle-aged subjects, via mechanisms that could include reduced stem cell proliferation, changed growth factor expression and/or reduced expression of synaptic plasticity genes. Although antidepressants alter these mechanisms in young rodents, their effects in older animals are unclear. In middle-aged mice, we examined the effects of a selective serotonin reuptake inhibitor (fluoxetine) and a multimodal antidepressant (vortioxetine) on cognitive and affective behaviors, brain stem cell proliferation, growth factor and gene expression. Twelve-month-old female C57BL/6 mice exhibited impaired visuospatial memory in the novel object placement (location) task associated with reduced expression of several plasticity-related …

Relationship Between Health-Maintenance Preferences And Health, Kiara Dillard

Posters, Presentations, and Papers

This study examines the relationship between people’s general health and their health-maintenance practices, specifically, the use of over-the-counter medications (OTCs) and home remedies. These practices are used by many; however, there is still much uncertainty about how these impact one’s health. Subjects for this study are drawn from the Behavioral Sciences Research Participation Pool and will complete an adapted questionnaire taken from the Questionnaire to Document Self-Medicating Behaviours and the SF-36 Health Survey.

Hypothesis and Research Question:

Does one’s preferred self-medication practice relate to health?

There is a relationship between at least one of these forms of self-medication practices and …

Man’S Search For Meaning: The Case Of Legos Revisited, Michael Choi

Posters, Presentations, and Papers

How do perceived meaning, levels of resilience, and job-rotation affect productivity and labor supply? Answering this question will provide further insight on how manipulating tasks can influence labor supply, motivation, and productivity in almost any field of labor, such as school and the workplace. Further, this study will explore motivation and the “least-common-denominator of meaningfulness that is shared by virtually all compensated activities” (Ariely et. al., 2008). This study is a replication and extension upon Man’s search for meaning: The case of Legos (Ariely et. al., 2008).

Family Matters!: Examining The Relationship Between Family Climate And Suicidality, Depression, And At-Risk Behaviors Among Seventh-Day Adventist Adolescents World-Wide, Isaac Suh

Posters, Presentations, and Papers

Recent research indicates that suicide is a growing cause of death in our country (CDC, 2010). Over the twelve year period (1999 to 2012), suicide rates increased by a staggering 40%. This is especially evident among adolescents (13-17 years). In spite of this trend, much remains to be known about the variability of this phenomenon across various subcultures. This study examines suicidal ideation and the effect of various demographic, psycho-social, and religious predictors among adolescents of a conservative religious denomination.

Research Question:

How does family climate effect the instances of at risk behaviors in adolescents in a conservative religious population?

Transformational Leadership, Diversity, And Creativity At Work: A Moderated Mediation Model, Aisha Smith Taylor

Dissertations and Theses

Organizational leaders often seek to hire and retain innovative employees as a source of competitive advantage. Both transformational leadership and effectively managed workplace diversity have been theorized and shown to lead to increased employee creative performance at work; however, a full model of the relationships between leadership and the multi-dimensional construct of workplace diversity has not yet been tested. Using a sample of 371 employees in three Chinese high-technology firms matched with 64 supervisors collected at three time points, this study theorized and tested a moderated mediation path model in which transformational leadership and diversity climate were predicted to significantly …

Perceived And Actual Similarity As Predictors Of Self-Disclosure And Perceived Understanding At Zero Acquaintance, Rebecca A. Martin

Theses and Dissertations

When people interact, there are general guidelines that direct the conversation. When two humans interact for the first time, however, there seem to be different factors at play that either allow for the relationship to continue and grow or that end any further interactions. One of the main factors in beginning relationships is the amount self-disclosure that is occurring between the people. Because social relationships are so important for humans, it is important to examine variables that may affect the amount people disclose when they first meet. This study looks at how perceived and actual similarity predict perceived understanding and …

Object Permanence In The Dwarf Goat (Capra Aegagrus Hircus): Perseveration Errors And The Tracking Of Complex Movements Of Hidden Objects, Christian Nawroth, Eberhard Von Borell, Jan Langbein

Memory Collection

Object permanence is the notion that objects continue to exist even when they are out of an observer’s sight. In mammals, the highest stage of object permanence (Stage 6) has been observed only in primates, whereas other species have shown difficulty in following once-hidden objects, particularly when complex movements are involved. We conducted four experiments to examine the ability of dwarf goats to mentally represent once-hidden objects. In Experiment 1, we investigated whether dwarf goats are prone to commit the A-not-B or perseveration error which is commonly used as a measure for self-control. Subjects here continue to search for an …

The Divergent Effects Of Fear And Disgust On Inhibitory Control: An Erp Study., Mengsi Xu, Zhiai Li, Cody Ding, Junhua Zhang, Lingxia Fan, Liuting Diao, Dong Yang

Education Sciences and Professional Programs Faculty Works

Negative emotional stimuli have been shown to attract attention and impair executive control. However, two different types of unpleasant stimuli, fearful and disgusting, are often inappropriately treated as a single category in the literature on inhibitory control. Therefore, the present study aimed to investigate the divergent effects of fearful and disgusting distracters on inhibitory control (both conscious and unconscious inhibition). Specifically, participants were engaged in a masked Go/No-Go task superimposed on fearful, disgusting, or neutral emotional contexts, while event-related potentials were measured concurrently. The results showed that for both conscious and unconscious conditions, disgusting stimuli elicited a larger P2 than …

Fusion Analysis Of Functional Mri Data For Classification Of Individuals Based On Patterns Of Activation., Mahdi Ramezani, Purang Abolmaesumi, Kris Marble, Heather Trang, Ingrid Johnsrude

Brain and Mind Institute Researchers' Publications

Classification of individuals based on patterns of brain activity observed in functional MRI contrasts may be helpful for diagnosis of neurological disorders. Prior work for classification based on these patterns have primarily focused on using a single contrast, which does not take advantage of complementary information that may be available in multiple contrasts. Where multiple contrasts are used, the objective has been only to identify the joint, distinct brain activity patterns that differ between groups of subjects; not to use the information to classify individuals. Here, we use joint Independent Component Analysis (jICA) within a Support Vector Machine (SVM) classification …

Political Skill Dimensionality And Impression Management Choice And Effective Use, Robyn L. Brouer, Rebecca L. Badaway, Vickie C. Gallagher, Julita A. Haber

Business Faculty Publications

Purpose The purpose of this study was to test a moderated mediation model of the dimensionality of political skill on influence tactic choice and performance ratings. Design/Mythology/Approach Dyadic data were analyzed using a mixed-method approach to account for any leaderlevel effects, as well as bootstrapping methods to account for the modest sample size (n = 116). Findings Social astuteness best predicted positive impression management (IM) over negative IM. Apparent sincerity interacted with positive impression management tactics to predict higher performance ratings, whereas interpersonal influence did not. Implications The findings support that socially astute individuals use more positive influence tactics in …

Investigating Hostility In A Retail Setting, Carlos D. Martinez

Communication Studies

Although there have been many changes in the way Americans shop, particularly the increase in eCommerce, studies have shown that 90% of all United States retail sales still happen in stores. This statistic highlights the continued importance of the in-store experience for the customer. Retail stores constantly rely on atmospherics to try and persuade the customers to make purchases and this study focuses on the use of mirrors to see if they can influence a customer’s attitude when a customer has encountered an unsettling situation.Specifically, this study was designed to investigate the possibility of using mirrors to aid in the …

Rejection Sensitivity, Perceived Power, And Hiv Risk In The Relationships Of Low-Income Urban Women, Kathy R. Berenson, Christine Paprocki, Marget Thomas Fishman, Devika Bhushan, Nabila El-Bassel, Geraldine Downey

Psychology Faculty Publications

The psychological processes associated with HIV infection in long-term relationships differ from those operative in casual sexual encounters, and relatively little research has considered the aspects of personality applicable in the ongoing heterosexual relationships in which women are at greatest risk. Sensitivity to rejection has been linked with efforts to prevent rejection at a cost to the self and, therefore, may be relevant to the health risks that many women incur in relationships. We examined the association of rejection sensitivity with women's sexual risk behavior in a sample of women at heightened risk for HIV exposure. Women in long-term heterosexual …

Navajo Nation Brain Drain: An Exploration Of Returning College Graduates' Perspectives, Quintina Ava Adolpho

Theses and Dissertations

American Indian tribes face the phenomenon known across the world as the brain drain. They invest millions of dollars in educating their members, only to have little return on their investments. Many nation members leave reservations to get postsecondary education but never return, contributing to the brain drain. Those who get education off the reservation and choose to return are the exceptions to this rule. Although there is an abundance of literature regarding the brain drain across the world, there has been little research done with American Indians. In order to begin to understand the brain drain phenomenon this study …

Researching Mbti Personality Types: Project Management Master’S Degree Students, Thomas G. Henkel, James W. Marion Jr, Debra T. Bourdeau

Publications

The purpose of this research study was twofold: 1) to explore if a university’s Master of Science in Project Management students’ MBTI® personalities differ significantly; 2) to gain a better understanding if the MBTI® personality traits of university students enrolled in a project management degree differ significantly from those MBTI® personalities of the general population. The goodness of fit test was used in order to test the hypotheses that the 177 graduate project management students (observed data) have the same MBTI® distribution as in the general population (expected data). Overall, the present study showed that the student population has 27.18% …

Four Lessons Learned From Treatingcatholic Priest Sex Offenders, Thomas G. Plante

Psychology

Perhaps there is no one in our society more despised and vilified than sex offenders, especially those who sexually violate young children. And during the past decade perhaps no particular subgroup of sex offender has been more despised than those who are Roman Catholic priests. We need to be attentive to the state-of-the-art facts, best practices, and create policies and procedures to keep those who might harm children away from children. To do otherwise is foolish and harmful. Yet strong opinions, advocacy, and hysteria sometimes gets more attention than actual evidence-based quality research and practice which is not ultimately in …

Peer Mentoring And The First Year Experience, Aiden Carthy, Peer Mentoring Resources Limited

Other Resources

The transition from secondary level learning to independent study can be difficult to negotiate and many students also experience emotional pressures as they adjust to a busy social environment at college (McAleavy, Collins and Adamson 2004 ; O’Reilly 2008). Many third level institutions are exploring ways to improve the first year experience and one such approach that has gained increasing interest in recent years is the provision of peer mentoring. This paper outlines and evaluates a pilot peer mentoring programme that was conducted with first year business students (n = 112) from three separate courses at a third level institution …

Cultural Adaptation And Implementation Of Evidence-Based Parent Training: A Systematic Review And Critique Of Guiding Evidence, Ana A. L. Baumann, Byron J. Powell, Patricia L. Kohl, Rachel G. Tabak, Valentina Penalba, Enola K. Proctor, Melanie M. Domenech-Rodriguez, Leopoldo J. Cabassa

Psychology Faculty Publications

With advances in knowledge regarding efficacious evidence-based interventions, there have been significant attempts to culturally adapt, implement, and disseminate parent training interventions broadly, especially across ethnic and cultural groups. We sought to examine the extent to which researchers and developers of evidence-based parent training programs have used cultural adaptation models, tested implementation strategies, and evaluated implementation outcomes when integrating the interventions into routine care by conducting a systematic review of the literature for four evidence-based parent training interventions: Parent-Child Interaction Therapy (PCIT), The Incredible Years (IY), Parent Management Training-Oregon Model (PMTO™), and the Positive Parenting Program (Triple P). A total …

Caregiving, Services, And Advocacy Among Siblings Of Individuals With Disabilities, John Kramer, Thinkwork! At The Institute For Community Inclusion At Umass Boston

All Institute for Community Inclusion Publications

In today’s presentation, we will make a case for how and why a critical disability studies perspective would deepen and strengthen our knowledge about the lifelong experiences of siblinghood. We have a wide range of goals today and will present for you some of our current thinking on this relatively small, but expanding interest in sibling-disability research. First, we highlight how sibling disability research has differed and been narrower in focus than other research about siblings where neither has a disability and trace the reason for this to institutionalisation and deinstitutionalisation. We then identify the impact of the overwhelmingly psychological …

Sleep Hygiene Practices: A Cross Cultural Survey Of Sleeping And Dreaming In College Students, Ivan Noe Martinez Salazar

Masters Theses

There is consensus that a sizeable percentage of people in most developed countries do not obtain adequate amounts or quality of sleep. These disruptions in sleep, when chronic and severe, can lead to psychological, behavioral and health consequences. The focus on behavioral and contextual factors that impact sleep has been termed “sleep hygiene”. An on-line anonymous survey collected sociodemographic information, as well as self-reports on sleep, sleep hygiene practices and dreaming across two cultural groups (English & Spanish speaking responders). A total of 204 participants (majority of them college and graduate students) answered the survey. Both cultural groups, English and …

Differential Effects Of Methylenedioxypyrovalerone (Mdpv) And Mephedrone In Rats Trained To Discriminate Mdma Or A D-Amphetamine+Mdma Mixture, Eric Louis Harvey

Masters Theses

Recent reports on the abuse of novel synthetic cathinone derivatives call attention to serious public health risks of these substances. In response to this concern, a growing body of preclinical research has characterized the psychopharmacology of these substances, particularly mephedrone (MEPH) or methylenedioxypyrovalerone (MDPV), noting their similarities to MDMA and cocaine. The present study employed drug discrimination methodology to assess the discriminative stimulus effects of MEPH and MDPV in male Sprague-Dawley rats trained to discriminate 1.5 mg/kg 3,4 methylenedioxymethamphetamine (MDMA) or a mixture of 1.5 mg/kg MDMA and 0.5 mg/kg d-amphetamine (MDMA+AMPH). After establishing dose response functions with each training …

Effects Of Altering Motivation In Pigeons Performing A Titrating-Delayed-Matching-To-Sample Task, Zachary J. Zimmermann

Masters Theses

In order to better understand the role motivating operations (MOs) serve in preceding and evoking behavior, it is useful to examine the effects of whether manipulating motivation can influence performance on tasks with known behavioral outcomes. It is well established that altered stimulus control is responsible for changes in responding on tasks of generalization and discrimination. Therefore, if stimulus control could be influenced by MOs, then perhaps stimulus discriminations could be improved by manipulating the relevant MO. To this end, the effects of altering motivation via food deprivation were examined in pigeons using a titrating-delayed-matching-to-sample task. Additional pharmacological variables (i.e., …

The Effects Of Varied Opportunities To Respond Embedded In A Group Contingency Program, Teresa Donna Bolt

Student Works

This study investigated the effects of using a group contingency program with three students with disabilities in a small group special education setting. These students exhibited both academic and behavioral difficulties. With the use of Class Wide Function-Related Intervention Team (CW-FIT) students increased their active engagement and correct responses, as well as decreased their disruptive behaviors; however, these behaviors did not maintain over time. CW-FIT with high opportunities to respond showed an even greater improvement than CW-FIT with low opportunities to respond. Increased opportunities to respond resulted in higher levels of active engagement and correct responses and decreases in disruptive …

A qualitative case study approach was used to explore the views, experiences, and motivations of obstacle course racing (OCR) participants. Descriptive statistics and cross tabulation was used to interpret responses to the 297 online questionnaires. A content analysis approach was used to analyze the qualitative data gathered from three focus groups with a total of 20 obstacle course racers. Three theories formed the basis of the study: Self-Determination Theory (SDT), Achievement Goal Theory (AGT), and Social Leaning Theory (SLT). Overall, findings supported previous research …

Longitudinal Association Between Self-Esteem In Adolescence And Posttraumatic Stress Disorder In Older Adults: A Cohort Study, John Anthony Blue Star

Student Works

Background: Posttraumatic-Stress Disorder (PTSD) is less common in older adults than in younger adults, and little is known about specific risk factors for PTSD in older adults. We investigated the association between self-esteem in late adolescence and PTSD in older adults. Method: Using a cohort design, 1,436 individuals who had been assessed approximately 40 years earlier in their junior and senior year of high school with the Rosenberg Self-Esteem Scale (RSES) were evaluated for PTSD using the PTSD Checklist (PCL-17). Results: Fully controlled logistic regression models indicated that lower self-esteem in late adolescence predicted PTSD in the overall sample of …

Disaster Relief And Psychological First Aid, Jenny Haeyeon Cho

Loma Linda University Electronic Theses, Dissertations & Projects

Many organizations that assist in the aftermath of disasters often do not provide psychological relief. Although people tend to be rather resilient in the face of traumatic events, the psychological distress and possible psychopathology that can ensue should not be taken lightly. This manual was created to be used as a training tool for those involved in disaster relief and aid work. A review of the literature, mental health disorders, basic information about disasters, common stress reactions, and Psychological First Aid are included. Although Psychological First Aid has not really been systematically studied, it appears to be promising in aiding …

Weight Stigma As A Mediator Among Bmi, Childhood Overweight, Body Image And Depression, Serena D. Stevens

Loma Linda University Electronic Theses, Dissertations & Projects

Higher body mass index (BMI), childhood overweight, and weight stigmatization are correlated with depression and body dissatisfaction. Given that overweight/obese individuals are likely to experience significant weight stigma, the goal of the current study was to examine the effects of current weight and childhood overweight on depression and body dissatisfaction, and to examine weight stigmatization as a mediator in these relationships. Participants were 380 undergraduate students from the University of South Florida (84.5% female) with a mean age of 21.18 (SD = 4.32) and a mean BMI of 23.86 (SD = 5.03). Of these students, 53.4% were White, 24.7% were …
