Changes In Eeg During Ultralong Running, M. Doppelmayr, P. Sauseng, H. Doppelmayr, I. Mausz

Journal of Human Performance in Extreme Environments

There are only a few studies using human electroencephalograms (EEGs) to investigate bioelectrical changes in the brain during exercise (running or cycling). These studies report an increase in EEG alpha amplitude during and immediately after exercise. However, only exercises within a relatively short time interval of approximately 1 hour have been investigated. Thus, we focussed on long-lasting exercise and report three single case studies, performed on the same participant, during extended exercise and under different thermal conditions. EEG was recorded during a 12-, 24-, and 56-hour ultramarathon. The 56-hour race was performed under extreme thermal stress in Death Valley, CA, …

Care For The Socially Disadvantaged: The Role Of Race And Gender On The Physician-Patient Relationship And Patient Outcomes In A Safety Net Primary Care Clinic., Daniel Baughn

Theses and Dissertations

Compared to the general population, socially disadvantaged patients have higher rates of chronic illness and require more complex medical care. They also endorse higher levels of psychological distress and tend to engage in behavioral risk factors such as poor diet, physical inactivity, and smoking. These issues are particularly concerning given that this population tends to adhere less to medical recommendations, has limited access to health resources, and receives poorer treatment from providers. In an effort to address this disparity, The Affordable Care Act will expand health care access to an additional 23 million uninsured and 17 million underinsured Americans. However, …

Sleep Disturbance Implications For Modern Military Operations, Douglas R. Lindsay, Jeff Dyche

Journal of Human Performance in Extreme Environments

As is evident from current military operations that are happening around the globe (e.g., Iraq, Afghanistan, Korea), today’s military is being called on in numerous new and innovative ways (e.g., Foster & Lindsay, 2011). One of the primary forces behind this change is the pervasiveness of enhanced information systems. In fact, the concept of networked warfare is the basis of operations and doctrine for the armed forces (Wesensten, Belenky, & Balkin, 2005). With respect to Admiral Cebrowski’s quote, it appears that this notion of information in warfare is going to continue to influence the way that we approach and conduct …

Algorithmic Decomposition Of Shuffle On Words, Franziska Biegler, Mark Daley, Ian Mcquillan

Brain and Mind Institute Researchers' Publications

We investigate shuffle-decomposability into two words. We give an algorithm which takes as input a DFA M (under certain conditions) and determines the unique candidate decomposition into words u and v such that L(M) = u v ifM is shuffle decomposable, in time O(|u| + |v|). Even though this algorithm does not determine whether or not the DFA is shuffle decomposable, the sublinear time complexity of only determining the two words under the assumption of decomposability is surprising given the complexity of shuffle, and demonstrates an interesting property of the operation. We also show that for given words u and …

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 …

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 …

A Hybrid Brain-Computer Interface Based On Motor Intention And Visual Working Memory, Ching-Chang Kuo

Doctoral Dissertations

Non-invasive electroencephalography (EEG) based brain-computer interface (BCI) is able to provide alternative means for people with disabilities to communicate with and control over external assistive devices. A hybrid BCI is designed and developed for following two types of system (control and monitor).

Our first goal is to create a signal decoding strategy that allows people with limited motor control to have more command over potential prosthetic devices. Eight healthy subjects were recruited to perform visual cues directed reaching tasks. Eye and motion artifacts were identified and removed to ensure that the subjects' visual fixation to the target locations would have …

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 …

Sense Beauty Via Face, Dressing, And/Or Voice, Tam Nguyen, Si Liu, Bingbing Ni, Jun Tan, Yong Rui, Shuicheng Yan

Computer Science Faculty Publications

Discovering the secret of beauty has been the pursuit of artists and philosophers for centuries. Nowadays, the computational model for beauty estimation has been actively explored in computer science community, yet with the focus mainly on facial features. In this work, we perform a comprehensive study of female attractiveness conveyed by single/multiple modalities of cues, i.e., face, dressing, and/or voice, and aim to uncover how different modalities individually and collectively affect the human sense of beauty. To this end, we collect the first Multi-Modality Beauty (M²B) dataset in the world for female attractiveness study, which is thoroughly annotated …

Asymmetry In Resting Alpha Activity: Effects Of Handedness, Ruth E. Propper, Jenna Pierce, Mark W. Geisler, Stephen D. Christman, Nathan Bellorado

Department of Psychology Faculty Scholarship and Creative Works

Frontal electroencephalographic (EEG) alpha band power during rest shows increased right, and/or decreased left, hemisphere activity under conditions of state or trait withdrawal-associated effect. Non-right-handers (NRH) are more likely to have mental illnesses and dispositions that involve such withdrawal-related effect. The aim of the study was to examine whether NRH might be characterized by increased right, relative to left, hemisphere activity during rest. Methods: The present research investigated that hypothesis by examining resting EEG alpha power in consistently-right-handed (CRH) and NRH individuals. Results: In support of the hypothesis, NRH demonstrated decreased right hemisphere alpha power, and therefore increased right hemisphere …

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 …

The Reminiscence Effect In Autobiographical Memory And Tests Of Its Prominent Accounts, Justin T. Coleman

Department of Psychology: Dissertations, Theses, and Student Research

The reminiscence effect, in which people aged 40 and over remember more autobiographical memories from between ages 10 to 30 than from adjacent periods, producing a “bump” in lifespan distributions, is a highly robust effect. When it was discovered to occur for highly positive emotional memories, but not negative ones, the cultural life script account of reminiscence was proposed. The cultural life script account asserts that individuals possess scripts for important events in the normative life that structure autobiographical recall. The reminiscence effect is explained by the fact that in life scripts, positive events have highly prescribed timings and cluster …

Cusp Catastrophe Models For Cognitive Workload And Fatigue In A Verbally Cued Pictorial Memory Task, Stephen J. Guastello, Henry Boeh, Michael Schimmels, Hillary Gorin, Samuel Huschen, Erin Davis, Natalie E. Peters, Megan Fabisch, Kirsten Poston

Psychology Faculty Research and Publications

Objective: The aim of this study was to evaluate two cusp catastrophe models for cognitive workload and fatigue. They share similar cubic polynomial structures but derive from different underlying processes and contain variables that contribute to flexibility with respect to load and the ability to compensate for fatigue.

Background: Cognitive workload and fatigue both have a negative impact on performance and have been difficult to separate. Extended time on task can produce fatigue, but it can also produce a positive effect from learning or automaticity.

Method: In this two-part experiment, 129 undergraduates performed tasks involving spelling, arithmetic, memory, and visual …

The Long Term Effect Of Parental Involvement In A Child's Education: A Ten-Step Approach, Eraina Ross-Aseme

Doctoral Dissertations and Projects

Parental Involvement in a child's education is very important to the child becoming a productive citizen. Some parents find themselves getting in at the start of their child entering elementary school; parental involvement should begin before the school age years. Research has demonstrated the effectiveness of establishments such as schools, churches and businesses partnering in a child's education. The goal of this project is to empower parents to build stronger support systems with schools, neighborhoods, churches and communities. Its aim is to show parents, school systems and businesses that collaboration in the education arena can be strengthened to achieve a …

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) …

The Impact Of Ambiguous Versus Blatant Race Related Stress On Ego Depletion In African American Adults, Benita Belvet

Theses and Dissertations

The aim of the current study was to examine variations in the impact of ambiguous versus blatant race related stressors on ego depletion in a sample of African American adults. Blatant race related stress was compared with ambiguous race related stress in regards to the relative impact on the constructs of ego depletion and perseverative cognition. Perseverative cognition was also examined as a potential mediating variable in the relationship between race related stress and ego depletion. Additionally, attributional ambiguity was hypothesized to moderate the effect of race related stress on perseverative cognition. The study implemented an experimental design, and assessed …

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 …

Evaluation Of An Early Intervention Program Using Eligibility Criteria, Emily Kurlansik

Theses and Dissertations

Early Intervention programs are state and federally funded programs that are available in virtually every state that provide support to children birth to three who have developmental delays. Eligibility into the program varies by state and determining eligibility for a child is a complex task that has tremendous implications on both the program and its children. A program evaluation was conducted on a branch of an early intervention program located in New Jersey to determine whether service providers were correctly identifying children who were eligible for services. Results indicated that four of out the 112 children in the program were …

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 …

An Examination Of Exposure To Traumatic Events And Symptoms And Strengths For Children Served In A Behavioral Health System Of Care, Melissa L. Whitson, Christian M. Connell, Stanley N. Bernard, Joy S. Kaufman

Psychology Faculty Publications

The present study examined how exposure to traumatic events impacts children with severe emotional disturbance who are being served in a school-based system of care. Multilevel growth curve models were used to examine the relationships between a child’s history of traumatic events (physical abuse, sexual abuse, or domestic violence) and behavioral and emotional strengths, internalizing problem behaviors, or externalizing problem behaviors over 18 months. Results indicate that children receiving services (N = 134) exhibited increased emotional and behavioral strengths and decreased internalizing and externalizing problem behaviors from enrollment to 18 months follow-up. Children with a history of traumatic events improved …

Practitioner Responses To Dsm Categorization Of Hoarding, Megan Martins, Valerie Smith

Modern Psychological Studies

The Obsessive Compulsive Disorder subtype, Hoarding, is a growing topic of interest in the field of Psychology. Many researchers have debated over whether Hoarding should be categorized as a subtype of Obsessive Compulsive Disorder or as its own separate disorder because of the insufficient research on Hoarding. This study sought to find out what other licensed psychologists' opinions were on the debate. Twenty one females and eight males participated in a survey that consisted of questions covering three domains: attachment, beliefs, and decision-making. This survey also included an essay question which the participants may elaborate further on what their opinions …
