Effects Of Ownership Intuitions On Allocations In The Dictator Game, John Christner

All Theses and Dissertations (ETDs)

People’s implicit assumptions about ownership might influence their decisions in Dictator Games: DG), leading to generosity. Two studies tested subjects’ intuitions concerning ownership in fictional situations structurally analogous to the DG. Subjects read a story about a ritual in which an old man: experimenter in DG) provided an endowment that Person 1: dictator in DG) had to allocate between self and Person 2: receiver in DG). Subjects were told that in some instances the ritual was interrupted before completion. As an assay of their intuitions regarding ownership, subjects were asked who owned the endowment and how it should be allocated …

Cardiovascular Reactivity In Friendships: Length Of Relationship And Frequency Of Contact As Potential Moderators, Benjamin D. Clark

Theses and Dissertations

Social support has been linked to positive health outcomes. Specifically, having available support from a friend may act as a buffer to the negative effects of stress on cardiovascular reactivity. Relationship quality is an important moderator of this effect. The purpose of this study was to examine how cardiovascular reactivity is affected by relationship quality within friendships and whether the length of relationship and frequency of contact may moderate the effect. 134 healthy male and female adults (and their same-sex friend) were recruited to participate. Results revealed no significant difference between subjects interacting with supportive friends compared to interacting with …

The Serotonin Transporter Gene Linked Polymorphic Region Is Associated With The Behavioral Response To Repeated Stress Exposure In Infant Rhesus Macaques, Simona Spinelli, Melanie L. Schwandt, Stephen G. Lindell, Markus Heilig, Stephen J. Suomi, James Dee Higley, David Goldman, Christina S. Barr

Faculty Publications

The short allele of the serotonin transporter linked polymorphic region (5-HTTLPR) moderates the effects of stress on vulnerability to mood and anxiety disorders. The mechanism by which this occurs may relate to differential sensitivity to stressful life events. Here we explored whether 5- HTTLPR and sex affected behavioral responses to repeated maternal separation in infant rhesus macaques. Behaviors were collected during the acute (Day 1) and the chronic (Days 2–4) phases of the separation, and the effects of duration of separation (acute vs. chronic), genotype (long/long vs. short allele), and sex (male vs. female) on behavioral responses were analyzed across …

Inspiration: Examining Its Emotional Correlates And Relationship To Internalized Values, David Jennings Ii

Theses and Dissertations

The study of inspiration as a psychological construct has received little empirical attention to date. In the present dissertation, I review the empirical literature on inspiration and present a theoretical model and definition of inspiration. In two studies, I tested a Value-Congruent Model of Inspiration and my proposed definition. In Study 1 (N = 134), I explored inspiration’s emotional correlates and tested whether individuals experience greater inspiration if the inspirational content is concordant with individual meaning and values. As predicted, state inspiration was positively related to state levels of admiration, awe, and elevation, and value-congruent stimuli significantly predicted self-reported experiences …

Teleological Reasoning In Adults: Believing In The Purpose Of Events, Carrie Jeanette Guggenmos

Masters Theses & Specialist Projects

Teleological reasoning reflects the general tendency to view objects, behaviors and events in terms of their “purpose.” Although healthy educated adults tend to refrain from committing errors in teleological reasoning about objects, our knowledge regarding how adults reason about events is limited. It has been suggested that teleological reasoning biases our interpretations of emotionally significant and unexpected life events of which a physical or social cause is absent or unsatisfactory. The current investigation seeks to better understand the types of events that evoke a teleological perspective and the conditions and individual difference factors that facilitate it. The results revealed that …

Identifying And Learning From Exemplary Volunteer Resource Managers: A Look At Best Practices In Managing Volunteer Resources, Amanda M. Backer, Joseph A. Allen, Daniel L. Bonilla

Psychology Faculty Publications

Nonprofit organizations thrive to the extent that their volunteer resource manager follows best practices for hiring, training, and managing volunteers. In an effort to identify some of the best practices in volunteer management, exemplary volunteer resources managers were identified from a consulting outreach program. These managers were then interviewed and the results from these interviews are presented here. Volunteer resource managers shared their best practices for improving volunteer organizational commitment, organizational recognition of volunteers, volunteer satisfaction with communication, volunteer perception of voice, volunteer competence & volunteer contribution, and volunteer burnouts & intentions to quit. In addition to presenting these practices, …

Acute Stress Influences Neural Circuits Of Reward Processing, Anthony J. Porcelli, Andrea H. Lewis, Mauricio R. Delgado

Psychology Faculty Research and Publications

People often make decisions under aversive conditions such as acute stress. Yet, less is known about the process in which acute stress can influence decision-making. A growing body of research has established that reward-related information associated with the outcomes of decisions exerts a powerful influence over the choices people make and that an extensive network of brain regions, prominently featuring the striatum, is involved in the processing of this reward-related information. Thus, an important step in research on the nature of acute stress’ influence over decision-making is to examine how it may modulate responses to rewards and punishments within reward …

Cocaine-Induced Reinstatement Of A Conditioned Place Preference In Developing Rats: Involvement Of The D2 Receptor, Kimberly A. Badanich, Cheryl L. Kirstein

Psychology Faculty Publications

Reinstatement of conditioned place preferences have been used to investigate physiological mechanisms mediating drug-seeking behavior in adolescent and adult rodents; however, it is still unclear how psychostimulant exposure during adolescence affects neuron communication and whether these changes would elicit enhanced drug-seeking behavior later in adulthood. The present study determined whether the effects of intra-ventral tegmental area (VTA) or intra-nucleus accumbens septi (NAcc) dopamine (DA) D2 receptor antagonist infusions would block (or potentiate) cocaine-induced reinstatement of conditioned place preferences. Adolescent rats (postnatal day (PND 28–39)) were trained to express a cocaine place preference. The involvement of D2 receptors on cocaine-induced reinstatement …

The Effects Of Response Interruption And Redirection On Language Skills In Children With Vocal Stereotypy, Tamara Leigh Perry

Master's Theses and Doctoral Dissertations

Vocal stereotypy is a common, skill-disruptive behavior in children with autism spectrum disorders (ASD). Response interruption and redirection (RIRD), the delivery of demands contingent on the occurrence of vocal stereotypy, is an intervention that is gaining empirical support for reducing vocal stereotypy and increasing appropriate language. However, little is known about the efficacy of RIRD when combined with early intensive behavioral intervention (EIBI), the recommended treatment approach for children with ASD, and its effects on the acquisition of language skills. Therefore, the purpose of this study was to evaluate the effects of RIRD when delivered during EIBI programming. Participants were …

When Less Is More: Evolutionary Origins Of The Affect Heuristic, Jerald D. Kralik, Eric R. Xu, Emily J. Knight, Sara A. Khan, William J. Levine

Dartmouth Scholarship

The human mind is built for approximations. When considering the value of a large aggregate of different items, for example, we typically do not summate the many individual values. Instead, we appear to form an immediate impression of the likeability of the option based on the average quality of the full collection, which is easier to evaluate and remember. While useful in many situations, this affect heuristic can lead to apparently irrational decision-making. For example, studies have shown that people are willing to pay more for a small set of high-quality goods than for the same set of high-quality goods …

Jewish Perspectives On Christian Privilege: A Consensual Qualitative Study, Robert Kinney

Seton Hall University Dissertations and Theses (ETDs)

Although multicultural considerations, privilege, and oppression are of current interest across the field, much of the extant research has failed to explore religiosity as a component of the psychological literature. Using Consensual Qualitative Research (CQR) the authors set out to gain an understanding of Christian privilege and the impact it has on Jewish Identity. A sample of 12 adult, American, non-Orthodox Jews were interviewed using a semi-structured interview protocol. The interview data was collected to better understand the manifestations of Christian privilege and the impact of said issues on participant’s lives and identities. Seven themes were identified (1) Personal Conceptualization …

Treating The Spirit: An Ethnographic Portrait Of Senegalese Animist Mental Health Practices And Practitioners In Dakar And The Surrounding Area, Caitlin Mckinley

Independent Study Project (ISP) Collection

Animist beliefs and practices are deeply ingrained in Senegalese society, even in the metropolitan area of Dakar and have prevailed in Senegal despite the many influences of Islam and colonization. Animist mental health practices are especially interesting because of the influx of Western mental health practices in the wake of modernization. Merging traditional and Western mental health practices challenges the completely different worldviews from which each school of thought stems. For those seeking treatment, this duality makes it tricky to receive the help that they need. The purpose of this study is to explore animist Senegalese mental health treatments, traditional …

Serotonin System Gene Polymorphisms Are Associated With Impulsivity In A Context Dependent Manner, Scott F. Stoltenberg, Christa C. Christ, Krista B. Highland

Department of Psychology: Faculty Publications

Impulsivity is a risk factor for adverse outcomes and characterizes several psychiatric disorders and risk for suicide. There is strong evidence that genetic variation influences individual differences in impulsivity, but the details are not yet understood. There is growing interest in better understanding the context dependency of genetic effects that is reflected in studies examining gender specificity, gene × environment interaction and epistasis (gene-gene interaction). In a cross-sectional study we examined whether polymorphisms in six serotonin system candidate genes and the experience of early life trauma (age 0–12) were associated with individual differences in impulsivity in a nonclinical sample of …

Size And Shape Information Serve As Labels In The Alarm Calls Of Gunnison’S Prairie Dogs Cynomys Gunnisoni, C. N. Slobodchikoff, William R. Briggs, Patricia A. Dennis, Anne-Marie C. Hodge

Veterinary Science and Medicine Collection

Some animals have the capacity to produce different alarm calls for terrestrial and aerial predators. However, it is not clear what cognitive processes are involved in generating these calls. One possibility is the position of the predator: Anything on the ground receives a terrestrial predator call, and anything in the air receives an aerial predator call. Another possibility is that animals are able to recognize the physical features of predators and incorporate those into their calls. As a way of elucidating which of these mechanisms plays a primary role in generating the structure of different calls, we performed two field …

Emotional Labor And Authentic Leadership, John E. Buckner V

Doctoral Dissertations

Organizational research has begun to once again focus on the importance of emotions in the workplace. In particular, the concept of emotional labor, the management of emotions at work to influence clients and customers, has recently received much attention. While research has addressed the impact of emotional labor on both employees and clients or customers, research has not examined emotional labor within the context of leadership.

Authentic leadership, an emerging construct in the study of leadership, is proposed to relate to emotional labor. Leaders' authentic behavior has been shown to positively impact followers, such as increasing trust in their leader …

Distinct Retinohypothalamic Innervation Patterns Predict The Developmental Emergence Of Species-Typical Circadian Phase Preference In Nocturnal Norway Rats And Diurnal Nile Grass Rats, William D. Todd, Andrew J. Gall, Joshua A. Weiner, Mark S. Blumberg

Faculty Publications

How does the brain develop differently to support nocturnality in some mammals, but diurnality in others? To answer this question, one might look to the suprachiasmatic nucleus (SCN), which is entrained by light via the retinohypothalamic tract (RHT). However, because the SCN is more active during the day in all mammals studied thus far, it alone cannot determine circadian phase preference. In adult Norway rats (Rattus norvegicus), which are nocturnal, the RHT also projects to the ventral subparaventricular zone (vSPVZ), an adjacent region that expresses an in-phase pattern of SCN-vSPVZ neuronal activity. In contrast, in adult Nile grass rats (Arvicanthis …

Drug–Drug Conditioning Between Citalopram And Haloperidol Or Olanzapine In A Conditioned Avoidance Response Model: Implications For Polypharmacy In Schizophrenia, Nathan L. Sparkman, Ming Li

Department of Psychology: Faculty Publications

Patients with schizophrenia often have anxiety and depression, and thus are treated with multiple psychotherapeutic medications. This practice of polypharmacy increases the possibility for drug–drug interactions. However, the pharmacological and behavioral mechanisms underlying drug–drug interactions in schizophrenia remain poorly understood. In the present study, we adopted a preclinical approach and examined a less known behavioral mechanism, drug–drug conditioning (DDC) between haloperidol (a typical antipsychotic) or olanzapine (atypical antipsychotic) and citalopram (a selective serotonin reuptake inhibitor). A rat two-way conditioned avoidance response paradigm was used to measure antipsychotic activity and determine how DDC may alter the antipsychotic efficacy in this model. …

A Comparison Of The Associative And Multiple Bearing Hypotheses Through Landmark Stability In Humans Using A Virtual Environment, Martha R. Forloines

College of Graduate Studies: Theses & Dissertations

The current experiment investigated the mixed results seen in spatial blocking paradigms; there have been procedures that have shown and not shown blocking of added landmarks in the spatial domain. Typically, the Associative theory of learning has been applied to spatial learning. However, spatial blocking paradigms cannot be explained solely with this theory. The Multiple Bearings Hypothesis (MBH) may be able to explain these differences. The current experiment employed a three-phase blocking paradigm to examine what factors are responsible for the mixed results. The first Phase, Phase 0, incrementally shaped human participants' goal location behavior with two ambiguous landmarks. In …

Neural Responses To Infants Linked With Behavioral Interactions And Testosterone In Fathers, Patty X. Kuo, Joshua Carp, Kathleen C. Light, Karen M. Grewen

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

Few fMRI studies have investigated the brain-behavioral basis of parenting in human fathers. Ten fathers were videotaped and gave salivary testosterone samples while interacting with their 2–4 month old infants, and viewed video clips of their own infant and an unfamiliar age-, ethnicityand sex-matched other infant during an fMRI protocol. Infant stimuli activated a network of prefrontal and subcortical brain regions. Furthermore, a subset of these regions activated significantly more to own (OWN) than other (OTHER) infants. Finally, neural responses to OWN versus OTHER were linked with paternal sensitivity, paternal reciprocity, and testosterone. In sum, our results provide a novel …

Oprm1 Gene Variation Influences Hypothalamic-Pituitary-Adrenal Axis Function In Response To A Variety Of Stressors In Rhesus Macaques, Melanie L. Schwandt, Stephen G. Lindell, James Dee Higley, Stephen J. Suomi, Markus Heilig, Christina S. Barr

Faculty Publications

The endogenous opioid system is involved in modulating a number of behavioral and physiological systems, including the hypothalamic-pituitary-adrenal (HPA) axis. In humans, a functional variant in the OPRM1 gene (OPRM1 A118G) is associated with a number of outcomes, including attenuated HPA axis responses to stress. A nonsynonymous variant (OPRM1 C77G) in the rhesus macaque has been shown to have similar effects in vivo to the human variant. The current study investigated whether OPRM1 C77G influences HPA axis response to stress in rhesus macaques. We analyzed plasma adrenocorticotropic hormone (ACTH) and cortisol levels measured in response to three different stressors: 1) …

A Theoretical Framework For Serious Game Design: Exploring Pedagogy, Play And Fidelity And Their Implications For The Design Process, Pauline Rooney

Journal Articles

It is widely acknowledged that digital games can provide an engaging, motivating and “fun” experience for students. However an entertaining game does not necessarily constitute a meaningful, valuable learning experience. For this reason, experts espouse the importance of underpinning serious games with a sound theoretical framework which integrates and balances theories from two fields of practice: pedagogy and game design (Kiili, 2005; Seeney & Routledge, 2009). Additionally, with the advent of sophisticated, immersive technologies, and increasing interest in the opportunities for constructivist learning offered by these technologies, concepts of fidelity and its impact on student learning and engagement, have emerged …

Supporting Children's Grief After A Death: A Guide For School Psychologists, Catherine Alexandra Bergeson

Theses and Dissertations

The death of a loved one is a significant stressor for children. Most children are exposed to grief at an early age. Without necessary support and guidance, children are much more susceptible to negative emotional, cognitive, and developmental effects. Expressive therapies such as bibliotherapy are supposed to provide a safe and healthy outlet for children's grief. However, school psychologists have limited pre-service training and readily available resources to effectively address children's death-related grief. This study included a survey of school psychologists from the National Association of School Psychologists (NASP) Crisis Management Group. Of the 431 potential members, 22% (N=95) responded …

Mother Goats Do Not Forget Their Kids’ Calls, Elodie F. Briefer, Mónica Padilla De La Torre, Alan G. Mcelligott

Sentience Collection

Parent–offspring recognition is crucial for offspring survival. At long distances, this recognition is mainly based on vocalizations. Because of maturation-related changes to the structure of vocalizations, parents have to learn successive call versions produced by their offspring throughout ontogeny in order to maintain recognition. However, because of the difficulties involved in following the same individuals over years, it is not clear how long this vocal memory persists. Here, we investigated long-term vocal recognition in goats. We tested responses of mothers to their kids’ calls 7–13 months after weaning. We then compared mothers’ responses to calls of their previous kids with …

Development Of Scn Connectivity And The Circadian Control Of Arousal: A Diminishing Role For Humoral Factors?, Andrew J. Gall, William D. Todd, Mark S. Blumberg

Faculty Publications

The suprachiasmatic nucleus (SCN) is part of a wake-promoting circuit comprising the dorsomedial hypothalamus (DMH) and locus coeruleus (LC). Although widely considered a "master clock," the SCN of adult rats is also sensitive to feedback regarding an animal's behavioral state. Interestingly, in rats at postnatal day (P)2, repeated arousing stimulation does not increase neural activation in the SCN, despite doing so in the LC and DMH. Here we show that, by P8, the SCN is activated by arousing stimulation and that selective destruction of LC terminals with DSP-4 blocks this activational effect. We next show that bidirectional projections among the …

Vocal Expression Of Emotions In Mammals: Mechanisms Of Production And Evidence, Elodie Briefer

Communication Skills Collection

Emotions play a crucial role in an animal’s life because they facilitate responses to external or internal events of significance for the organism. In social species, one of the main functions of emotional expression is to regulate social interactions. There has recently been a surge of interest in animal emotions in several disciplines, ranging from neuroscience to evolutionary zoology. Because measurements of subjective emotional experiences are not possible in animals, researchers use neurophysiological, behavioural and cognitive indicators. However, good indicators, particularly of positive emotions, are still lacking. Vocalizations are linked to the inner state of the caller. The emotional state …

Decoding Nonverbal Expressions Of Emotion Of Men And Women, Spencer Mac Adams

Modern Psychological Studies

In this experiment participants viewed 42 images of 7 different facial expressions and asked to identify the emotion associated with the expression. Participants were separated into a control group and an experimental group. Participants in the control group were shown 21 male and 21 female expressions of the following: Anger, Sadness, Happiness, Fear, Disgust, Surprise, and a Neutral expression; each presented 3 times. The experimental group was given the same procedure with the addition of phrases that accompanied the images that were either: congruent, incongruent, or unrelated to the expression. Accurately decoding the expression was measured and factors of significance …

The Control Of Posture In Newly Standing Infants Is Task-Dependent, Laura J. Claxton, Dawn Melzer, Jyoong Hyun Ryu, Jeffrey M. Haddad

Psychology Faculty Publications

The postural sway patterns of newly standing infants were compared under two conditions: standing while either holding or not holding a toy. Infants exhibited a lower magnitude of postural sway and more complex sway patterns when holding the toy. These changes suggest infants adapt postural sway in a manner that facilitates visually fixating on and stabilizing the toy in their hand. When simply standing, infants exhibited postural sway patterns that appeared to be more exploratory in nature. Exploratory sway patterns may allow infants to learn the affordances of their new standing posture. These results demonstrate newly standing infants are capable …

Relationships Between Food Reinforcement And Eating Behaviors To Bariatric Surgery Weight Loss And Substance Abuse Outcomes, Summar Reslan

Master's Theses and Doctoral Dissertations

Bariatric surgery is rapidly gaining acceptance among the morbidly obese population, yet studies assessing variables associated with post-surgical outcomes have yielded inconsistent findings. The purpose of this investigation was to assess the association between the relative reinforcing value of food (RRV-F), delay discounting for food (DD-F), and other eating-related and non eating-related variables to post-bariatric surgery percent total weight loss (%TWL) and substance-related outcomes. Participants were a convenience sample of 147 adults with a history of Roux-en-Y gastric bypass surgery. Using online survey methodology, variables that may contribute to post-surgical %TWL and substance use outcomes were assessed: the RRV-F, DDF, …
