Serotonin, Motivation, And Playfulness In The Juvenile Rat, Stephen M. Siviy, Loren M. Deron, Chelsea R. Kasten

Psychology Faculty Publications

The effects of the selective 5HT1A agonist 8-OH-DPAT were assessed on the play behavior of juvenile rats. When both rats of the test pair were comparably motivated to play, the only significant effect of 8-OH-DPAT was for play to be reduced at higher doses. When there was a baseline asymmetry in playful solicitation due to a differential motivation to play and only one rat of the pair was treated, low doses of 8-OH-DPAT resulted in a collapse of asymmetry in playful solicitations. It did not matter whether the rat that was treated initially accounted for more nape contacts or fewer …

Stress-Generation Processes In Latinos: The Roles Of Acculturation, Acculturative Stress, And Intercultural Competence, Mark W. Driscoll

Dissertations (1934 -)

Using a brief longitudinal design, this study examined the role of cultural adaptation processes (acculturation, acculturative stress, and intercultural competence) in predicting depression symptoms among Latinos living in the United States. Based on previous research employing stress generation processes (e.g., Hammen, 2005), it was hypothesized that depression symptoms measured at baseline predicted dependent stressful life events measured at six-month follow-up. It was further hypothesized that depression symptoms measured at baseline predicted dependent stressful life events measured at six-month follow-up indirectly through acculturation, acculturative stress, and intercultural competence, also measured at six-month follow-up. Finally, it was hypothesized that six-month follow-up acculturation, …

The Therapeutic Relationship In Dialectical Behavior Therapy: A Longitudinal Investigation In A Naturalistic Setting, Sara Elizabeth Little

Dissertations (1934 -)

The quality of the therapeutic alliance in psychotherapy has been found to be positively associated with many treatment outcome variables, such as client retention, client satisfaction in treatment, and improvement in symptoms. While some theorists assume that therapeutic alliance is established early in therapy and remains fairly stable across time in treatment, others such as Safran et al. (1990) suggest that the alliance quality fluctuates across time and is likely to be marked by frequent patterns of rupture and repair. In particular, individuals with Borderline Personality Disorder (BPD) have clusters of symptoms and interpersonal styles that are likely to present …

Influences On Father Involvement: Testing For Unique Contributions Of Religion And Spirituality, Mark Lynn

Dissertations (1934 -)

The role of the father in children's development historically has been neglected. Studies examining family processes were primarily limited to mothers, under the assumption that mothers' influences encapsulated what (little) effects could also be attributed to the father. Although theory and research have begun to address fathers' roles in families in earnest, there is still much work to be done, particularly in regard to understanding the determinants of father involvement. One direction that has received attention from researchers is towards a conceptualization of environmental and contextual influences on fathers' interactions with their families. The goal of this study was to …

Cognitive-Behavioral Group Treatment For A Sexually Abused Child And A Nonoffending Caregiver: Case Study And Discussion, Grace S. Hubel, Rosalita C. Maldonado, Poonam Tavkar, David J. Hansen, Mary Fran Flood

Department of Psychology: Faculty Publications

This study presents the case of 11-year-old Amanda and her mother (Ms. Jones) who completed Project SAFE (Sexual Abuse Family Education), a manualized group treatment for sexually abused children and their nonoffending caregivers. Amanda experienced sexual abuse by her stepfather on multiple occasions over a 4-year period. Prior to treatment, Amanda reported symptoms of anxiety, posttraumatic stress, and fear related to victimization. Ms. Jones also reported clinically significant internalizing problems for Amanda. Ms. Jones presented with stress related to parenting as well as depression and anxiety. Both Amanda and Ms. Jones completed the entire 12-session protocol. Amanda and Ms. Jones’s …

Acculturation, Cultural Values, And Latino Parental Beliefs About The Etiology Of Adhd, Kathryn E. Lawton

Master's Theses (2009 -)

Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most prevalent mental health disorders of childhood, but despite the availability of several evidence-based interventions, Latino children are more likely than non-minority children to have an unmet need for services related to ADHD. Because parental beliefs about the etiology of ADHD likely influence which services are sought, more research is needed to examine this aspect of help-seeking behavior in order to address the unmet need among Latino families. Specifically, research needs to focus on cultural factors that likely influence parental beliefs about the etiology of child behavior problems. Thus, the goal of the …

Effects Of Chronic Variable Stress Across Developmental Stages In Mice, Sheryl Jayne Stevens

Master's Theses (2009 -)

Posttraumatic Stress Disorder (PTSD) is a response to trauma exposure that involves a number of symptoms that can be highly impairing to affected individuals. Only a subset of those exposed to traumatic events will develop the disorder, which is conceptualized as developing via conditional fear. Research into factors predisposing for PTSD is needed. Furthermore, little work has been done to investigate predisposing factors in children more specifically. This research tests the effects of stress exposure on subsequent fear learning, across developmental stages in mice, as a model for PTSD. Juvenile and adult male mice were exposed to chronic variable stress …

Mate-Selection And The Dark Triad: Facilitating A Short-Term Mating Strategy And Creating A Volatile Environment, Peter K. Jonason, Katherine A. Valentine, Norman P. Li, Carmelita L. Harbeson

Research Collection School of Social Sciences

The current study (N = 242) seeks to establish the relationship between traits known collectively as the Dark Triad – narcissism, psychopathy, Machiavellianism – and mating standards and preferences. Using a budget-allocation task, we correlated scores on the Dark Triad traits with mate preferences for a long-term and short-term mate. Men scoring high on the Dark Triad may be more indiscriminate than most when selecting for short-term mates in order to widen their prospects. Furthermore, those high on the Dark Triad – psychopathy in particular – tend to select for mates based on self-interest, assortative mating, or a predilection for …

Economic Inequality Is Linked To Biased Self-Perception, Steve Loughnan, Peter Kuppens, Juri Allik, Katalin Balazs, Soledad De Lemus, Kitty Dumont, Rafael Gargurevich, Istvan Hidegkuti, Bernhard Leidner, Jennifer Yuk-Yue Tong

Research Collection School of Social Sciences

People’s self-perception biases often lead them to see themselves as better than the average person (a phenomenon known as self-enhancement). This bias varies across cultures, and variations are typically explained using cultural variables, such as individualism versus collectivism. We propose that socioeconomic differences among societies—specifically, relative levels of economic inequality—play an important but unrecognized role in how people evaluate themselves. Evidence for self-enhancement was found in 15 diverse nations, but the magnitude of the bias varied. Greater self-enhancement was found in societies with more income inequality, and income inequality predicted cross-cultural differences in self-enhancement better than did individualism/ collectivism. These …

The Steroid/Peptide Theory Of Social Bonds: Integrating Testosterone And Peptide Responses For Classifying Social Behavioral Contexts, Sari M. Van Anders, Katherine L. Goldey, Patty X. Kuo

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

Hormones, and hormone responses to social contexts, are the proximate mechanisms of evolutionary pathways to pair bonds and other social bonds. Testosterone (T) is implicated in trade-offs relevant to pair bonding, and oxytocin (OT) and arginine vasopressin (AVP) are positively tied to social bonding in a variety of species. Here, we present the Steroid/Peptide Theory of Social Bonds (S/P Theory), which integrates T and peptides to provide a model, set of predictions, and classification system for social behavioral contexts related to social bonds. The S/P Theory also resolves several paradoxes apparent in the literature on social bonds and hormones: the …

Healing Images: A Historical Outline Of Their Use In Western Medical And Psychotherapeutic Traditions, Anees A. Sheikh

Psychology Faculty Research and Publications

The ancient literature of numerous cultures abounds with accounts of spectacular cures resulting from the imaging process. These accounts are now being corroborated by a growing body of clinical and experimental evidence. The effectiveness of mental imagery in the treatment of a wide variety of problems has been convincingly documented (Sheikh, 1983). This paper outlines the use of imagery in Western medical as well as psychotherapeutic traditions. It concludes with a discussion of the reasons that make imagery an excellent healing agent.

Identity And Psychological Needs Among National Guard Service Members And Undergraduates, Bradley Antonides

Theses and Dissertations

This study measured identity style and identity status within military and academic populations (N = 286) to investigate whether low levels of identity commitment predict dissatisfaction in meeting basic psychological needs. Analysis of identity style and identity status subscales examined the reliability of traditional measures of identity in an atypical emerging adult population. Group comparisons based on participant characteristics (identity commitment, work experience, age, combat experience) explored differences between and within institutions. Results supported the reliability of traditional identity measures in a non-traditional population. A diffuse identity status and diffuse identity style both significantly predicted lower reported levels of psychological …

Picture Recognition Of Food By Macaques (Macaca Silenus), Peter G. Judge

Faculty Journal Articles

Pictorial representations of three-dimensional objects are often used to investigate animal cognitive abilities; however, investigators rarely evaluate whether the animals conceptualize the two-dimensional image as the object it is intended to represent. We tested for picture recognition in lion-tailed macaques by presenting five monkeys with digitized images of familiar foods on a touch screen. Monkeys viewed images of two different foods and learned that they would receive a piece of the one they touched first. After demonstrating that they would reliably select images of their preferred foods on one set of foods, animals were transferred to images of a second …

Addressing Work-Related Traumatic Stress Nebraska - Resilience Alliance Facilitator Manual, Acs-Nyu Children's Trauma Institute

Other QIC-WD Products

Child welfare staff are first responders; just like police officer and fire fighters, they are asked to respond to emergency situations with very little information, and by doing so often put themselves at risk. In addition to the very real physical risks involved with responding to a report of suspected child abuse or neglect, there are equally real psychological risks involved with taking care of children and families that have experienced abuse, neglect, family and community violence, and other traumas. Unlike police officers and fire fighters, however, child welfare staff get very little public recognition for the hard work they …

Gender Patterns In Dress And Outward Appearance: An Individual Choice Or Fulfillment Of Cultural Expectations?, Caroline J. Lindemuth, Lindsey A. Thomas, Hadley A. Mates, Jenessa A. Casey

Modern Psychological Studies

This study examines the extent to which males and females conform to gender schemas regarding outward appearance and clothing styles. Participants were observed from a distance in various natural settings and were coded based on estimated age, hair length, certain clothing choices, and certain jewelry and accessory choices. We found statistically significant gender differences (with p <.0001) for all characteristics, with the codes for hair length, earrings, and dresses showing the strongest discrepancies. These data showed a pattern of males being more confined to strict gender displays than were females, which can be seen particularly clearly in the wearing of earrings and dresses, as males rarely deviated from the socially acceptable gender signals. These findings imply that the feminist movement loosened feminine standards for dress and appearance; lacking a similar social movement, men remain more strictly confined to traditional displays of gender.

The Effects Of Video Game Play On Academic Performance, Jancee Wright

Modern Psychological Studies

The purpose of the present research is to determine whether playing video games impacts academic performance as determined by GPA. To accomplish this, 198 participants filled out a Gaming Habits Survey which was analyzed using a series of one-way ANOVAs. The study found that there was a significant effect of player status on GPA at the p < .01 level for the two conditions of player versus non-player [F (1, 169) = 7.08, p = .009]. Comparisons using descriptive statistics indicated that the mean GPA score for the player condition (M = 3.2, SD = .51) was significantly different than the non-player condition (M = 3.4, SD = .47). These results show that participants who indicated that they did play video games had significantly lower GPAs than participants who indicated that they did not play video games.

Memory For Emotional Images: Mechanisms Of Episodic Processing And Its Psychophysiological Correlates, Gregory E. Devore

Loma Linda University Electronic Theses, Dissertations & Projects

Negative emotional stimuli are usually better remembered than neutral emotional stimuli. Previous examination of binding theory found no differences in recall for pure lists of taboo and neutral words. A similar result was found with equivalent recognition memory performance between pure lists of negative, positive, and neutral images. The current research is designed to test the predictions of binding theory using negative and neutral visual stimuli in mixed lists. A rapid serial visual presentation paradigm and recognition memory item-discrimination tasks are used. Binding theory predicts differences in recognition memory performance between arousing and neutral images in mixed lists, but not …

Exploring Gender Differences In Online Cancer Support Groups, Natalie Christine Kaiser

Loma Linda University Electronic Theses, Dissertations & Projects

Gender differences in depression and other psychiatric conditions have been widely

documented in the general population (Nolen‐Hoeksema, 2006). Therefore, several studies have

analyzed the differential gender‐based adaptation of a cancer diagnosis. However, there seem to be contradictory results. While some studies have found there to be no gender differences in terms of cancer‐related distress (Beresford et al., 2006; Deimling et al., 2006; Zabora et al., 2001; & Carlson et al., 2004; Matthews, 2003), other studies have found that females tend to display more anxiety and depressive symptoms (Mystakidou et al., 2005; Deimling et al., 2006). Interestingly, limited studies have reported …

The Impact Of Pomegranate On Memory Dysfunction After Cardiac Surgery, Sapna Patel

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Studies have shown a decline in certain cognitive abilities in individuals diagnosed with heart disease of any type or etiology. This decline is observed as the disease progresses (Muller, Grobbee, Aleman, Bots & van der Schouw, 2006; Ernest et al., 2006), as well as after certain interventions, such as coronary artery bypass grafting (CABG) and heart valve surgery. In recent years, there has been a great deal of emphasis on the beneficial effects of pomegranate on health, including diseases of the brain and the heart. Few, however, have explored the impact of pomegranate on cognitive functions. Thus, the current …

Inpatient Stroke Rehabilitation: Ethnic And Psychosocial Predictors Of Recovery Outcome, Anna Olga Wong

Loma Linda University Electronic Theses, Dissertations & Projects

As the new focus on preventative medicine has emerged, research continues to expand on diseases that impact physical and cognitive functioning, lead to long-term disability, and increase the risk of mortality. Stroke or cerebral vascular accident (CVA) has been identified as one of such diseases by the Centers for Disease Control (2007). Past literature has identified disparities between ethnicity, socioeconomic status, and other diseases in the recovery of stroke. The aim of the current study was to investigate the effects of ethnicity and psychosocial factors on stroke recovery during inpatient rehabilitation. The study included 446 patients who had suffered an …

Guidelines For Culturally Informed Interventions: Culture, Attributions And Continuity Of Care, Chung Mu Seo

Loma Linda University Electronic Theses, Dissertations & Projects

Although early detection can improve survival of breast and cervical cancer, U.S. Latinas are more likely to be diagnosed at later stages of cancer and have poorer survival rates compared to Anglo women. Poorer continuity of care and adherence to recommended screening are seen as contributing factors to this disparity. Existing interventions have tried to reduce human, system, and culture barriers. However, they lacked a systemic guidance in the process of identifying cultural factors and the pathways in which they affect the specific behavior of interest through psychological processes in a minority population. Guided by Betancourt’s integrative model of culture, …

Lateralization Of Emotion, Reaction Time, And Skin Conductance Responsiveness, Kimberley Erin Rose

Loma Linda University Electronic Theses, Dissertations & Projects

Bilateral presentations of brief (250 ms), unmasked emotional and neutral stimuli were examined in two experiments with primarily female samples. Reaction time and accuracy data were used to measure perception of emotion and skin conductance response (SCR) was used to measure experience of emotion. Both words and pictures were used to account for hemispheric differences in language and visuospatial dominance. Response time was faster to emotional pictures than words. Reaction time and speeded accuracy data did not support right hemisphere hypothesis (RHH) or valence hypothesis (VH) in the expected manner. Data suggested emotion caused greater interference under speeded conditions in …

Integrating The Development Of Children And Gestalt Therapy, Jennifer J. Thompson

Loma Linda University Electronic Theses, Dissertations & Projects

There are many theories that have contributed to what we know about the development of children; for instance, theoretical diversity supports the complexities of human nature. A child's developmental level will impact his ability to relate. Gestalt theory supports the child's phenomenological view by focusing on the here-and-now of what is happening in the therapeutic environment. Most of what a child will do is in response to a need or want. The child will work toward fulfilling that need. The child may develop maladaptive ways to fulfill his needs based on the environment in which he lives. Gestalt play therapy …

The Application Of Dialectical Behavior Therapy To Chronic Pain Management, Jacob S. Iwaszewski

Loma Linda University Electronic Theses, Dissertations & Projects

Pain affects more than 50 million Americans annually, costs over 150 billion dollars each year in healthcare and legal expenses, and results in decreased work productivity and missed work days (Ballantyne, 2006; Boll, Raczynski, & Leviton, 2004; Thom, 2004). It is estimated that chronic pain negatively impacts 15% to 33% of the US population (Bokarius et al., 2008). Third-wave acceptance-based therapies, such as Dialectical Behavior Therapy (DBT), have demonstrated significant improvements in mental health functioning for a variety of populations (Carmody & Baer, 2008; Cusens, Duggan, Thome, & Burch, 2010). DBT, one of the primary treatment modalities for Borderline Personality …

Death, Etxtraversion, Commitment, And Sex: A Study On Terror Management, Jalaal Madyun, Wind Goodfriend

Modern Psychological Studies

Several studies have found that when confronted with mortality (i.e., mortality salience), the desire for intimate relationships and the desire for sex increase (Ben-Ari, 2004; Hirschberger, Florian, & Mikulincer, 2002). The current study examined desire for commitment to a romantic partner and the desire to engage in risky sexual behaviors when mortality is salient and added an examination of how these constructs overlap with the personality trait of extraversion. Results showed that, as expected, extraversion was correlated with the desire to engage in risky sexual behavior. Surprisingly, however, individuals under mortality salience were less likely to desire risky sexual encounters, …

Intact Statistical Word Learning In Autism Spectrum Disorders, Jessica Mayo

Master's Theses

Individuals with Autism Spectrum Disorders (ASD) have impairments in language acquisition, but the underlying mechanism of these deficits is poorly understood. Implicit learning appears potentially relevant to language development, particularly in speech segmentation, which relies on sensitivity to the transitional probabilities between speech sounds. This study aimed to investigate the relationship between implicit learning and current language abilities in school-aged children with autism (n = 17) and typical development (n = 24) using a well-studied artificial language learning task. Results suggest that the ASD and TD groups were equally able to implicitly learn transitional probabilities from a lengthy …

Cerebral Lateralization Determines Hand Preferences In Australian Parrots, Culum Brown, Maria Magat

Sentience Collection

Individual preference for the use of one limb over the other to explore the environment or manipulate objects is common trait among vertebrates. Here, we explore the hypothesis that limb preference is determined by the engagement of a particular cerebral hemisphere to analyse certain stimuli. We recorded the eye and foot preferences of 322 individuals from 16 species of Australian parrots while investigating potential food items. Across all species, eye preferences explained 99 per cent of the variation in foot use in Australian parrots. The vast majority of species showed significant relationships between eye and foot preferences at the population …

Insightful Problem Solving In An Asian Elephant, Preston Foerder, Marie Galloway, Tony Barthel, Donald E. Moore Iii, Diana Reiss

Publications and Research

The ‘‘aha’’ moment or the sudden arrival of the solution to a problem is a common human experience. Spontaneous problem solving without evident trial and error behavior in humans and other animals has been referred to as insight. Surprisingly, elephants, thought to be highly intelligent, have failed to exhibit insightful problem solving in previous cognitive studies. We tested whether three Asian elephants (Elephas maximus) would use sticks or other objects to obtain food items placed out-of-reach and overhead. Without prior trial and error behavior, a 7-year-old male Asian elephant showed spontaneous problem solving by moving a large plastic cube, on …
