Decision Making In Older Adults: A Comparison Of Delay And Probability Discounting Across, Ariana Vanderveldt

Arts & Sciences Graduate Student Theses and Dissertations

The value of an outcome is affected both by the delay until its receipt (delay discounting) and by the likelihood of its receipt (probability discounting). The discounting framework has greatly aided in modeling and understanding decision-making, particularly in the areas of impulsivity, but these findings have overwhelmingly been based on research with young adults. In three experiments, the current study extended the discounting framework by examining choice by older adults. Experiments 1 and 2 found that both young and older adults discounted delayed outcomes and probabilistic outcomes and that their choices were well-described by the same hyperboloid model. Both young …

Relationship Satisfaction And Health Outcomes In The Context Of Personality, Janine Galione

Arts & Sciences Graduate Student Theses and Dissertations

Self-reported dissatisfaction in romantic relationships is a well-documented risk factor for impaired physical health outcomes. Most research has focused on identifying the mechanisms that could potentially explain this link, but it is just as important to explore what type of person is more vulnerable to the quality of romantic relationships. Relationship satisfaction may be more consequential in the context of some personality traits than others. We examined whether each of the five factor traits interacts with self-reported relationship satisfaction to predict three health outcomes over 18 months: major physical health events, health perceptions, and health behaviors. The hypotheses for this …

Dynamic Adjustments Of Cognitive Control In Healthy Aging: A Diffusion Model Analysis, Andrew Jacob Aschenbrenner

Arts & Sciences Graduate Student Theses and Dissertations

The control of attention over salient yet irrelevant information is a critical component of goal-directed behavior. Compared to younger adults, older adults often produce larger interference effects in tasks which tap selective attention, a deficit that has typically been viewed as reflecting an age-related decline in attentional control processes. Interference in distinct, attentionally demanding tasks has produced different influences on the characteristics of underlying response time distributions leading to the assumption of different control mechanisms operating across various paradigms. More recently, accumulating research has shown that the magnitude of observed interference can be critically modulated by the congruency of the …

Perceiving Oldness In Parietal Cortex: Fmri Characterization Of A Parietal Memory Network, Adrian Gilmore

Arts & Sciences Graduate Student Theses and Dissertations

The manner in which the human brain recognizes certain stimuli as novel or familiar is a matter of ongoing investigation. The overarching goal of this dissertation is to improve our understanding of how this may be accomplished. More specifically, work contained herein focuses on a recently described "parietal memory network" (PMN; Gilmore et al., 2015) that shows opposite patterns of activity when perceiving novel or familiar stimuli: deactivating in response to novelty, and activating in response to familiarity. Critically, our understanding of this network is based on explicit memory tasks, in which subjects are deliberately instructed to learn or remember …

The Interaction Of Crystallized And Fluid Abilities In Aging And Speech Perception, Avanti Dey

Arts & Sciences Graduate Student Theses and Dissertations

In a series of studies, I examined the degree to which fluid and crystallized abilities contribute to and interact during speech perception. During the aging process, crystallized abilities (e.g., linguistic and word knowledge) are largely preserved, while fluid abilities involved in the online manipulation of information (e.g., working memory and inhibitory control) decline with age. Importantly, these two components are critical for successful speech perception and comprehension. While prior research has proposed that older adults rely on crystallized knowledge to compensate for cognitive deficits in difficult listening conditions, this hypothesis has not been directly tested. Younger and older adults completed …

Development And Validation Of The Palliative Care Knowledge Scale (Packs), Elissa Kozlov

Arts & Sciences Graduate Student Theses and Dissertations

Palliative care is a team-based, specialty service that improves the quality of life for individuals with serious illness and their families. However, current research suggests that this life-improving service is drastically underutilized. Patient knowledge of a healthcare service is theorized to drive utilization. If people do not know what palliative care is, they cannot be expected to seek out or accept a referral for the service. Currently, there are no psychometrically evaluated scales to assess knowledge of palliative care. The purpose of this study is to develop a reliable and valid scale that broadly measures knowledge about palliative care. An …

Age Differences In The Effects Of Semantic Context On Speech Perception: The Role Of Uncertainty., John Ryan Morton

Arts & Sciences Graduate Student Theses and Dissertations

Recent experiments have shown that semantic context effects on spoken word recognition differ between young and older adults (Rogers, Jacoby & Sommers, 2012; Sommers et. al, in prep). These experiments have shown that older adults provide significantly more incorrect responses than young adults when context predicts a phonological competitor that is semantically more likely than the actual target item. Incorrectly responding with the semantically predicted item rather than the true target item, with high confidence, is referred to as false hearing. The general design used in the studies reported for this dissertation is to compare identification of sentence-final items (presented …

Relationship Science And Interventions: Where We Are And Where We Are Going, Kieran T. Sullivan, Erika E. Lawrence

Psychology

Relationship distress and divorce often have profound effects on couples and their children. Relationship science has long sought to prevent and alleviate relationship distress; this chapter is a summary of many important recent developments in the field. Ongoing challenges in studying and assisting intimate relationships are also discussed.

Universal Modes Of Awareness? A “Pre-Reflective” Premise, Uta M. Jürgens

Animal Sentience

Mark Rowlands holds that creatures endowed with pre-reflective awareness may qualify as persons: In pre-reflective awareness, the self and the unity of mental life are implicit in the stream of experience. Rowlands generalizes from an introspective analysis of pre-reflective consciousness in humans to pre-reflective awareness in general. I describe three examples of empirical findings that corroborate the assumption that animal minds have some of the same basic modes of pre-reflective awareness as human minds.

Examining The Role Of Executive Functions In Focal Processing Of Event-Based Prospective Memory, Tatsuya T. Shigeta

Theses and Dissertations

Prospective Memory (PM) refers to remembering an intention to be acted upon in the future. Such a memory may be triggered by an event (i.e., Event-based PM) where a specific cue reminds one of the previously encoded intention. PM can be assessed in a lab-setting by having subjects learn a baseline task, subsequently receiving a PM instruction, completing a distractor task, and then going through a test phase where the PM task (i.e., responding to PM cues) is embedded within the ongoing task. The multiprocess view (McDaniel & Einstein, 2000) posits that PM can be retrieved primarily using two different …

Nurturing Compassion Development Among College Students: A Longitudinal Study, Thomas G. Plante, Katherine Halman

Psychology

Little research exists on the development of compassion among college undergraduates. This study tracks changes in compassion and identifies factors associated with these changes over the course of undergraduate students’ college careers, from the time of admittance to the time of graduation. Compassion levels assessed at the point of college entrance accounted for 25% of the variance in compassion at the time of graduation. These findings provided evidence for the notion that compassion can continue to be cultivated once in college. Predictors such as diversity training, the frequency of religious service attendance, participation in community-based service-learning, political identification, and feeling …

Are Prompts Provided By Electronic Books As Effective For Teaching Preschoolers A Biological Concept As Those Provided By Adults?, Gabrielle Strouse, Patricia Ganea

School of Education Faculty Publications

Research Findings: Prior research indicates that shared book reading is an effective method for teaching biological concepts to young children. Adult questioning during reading enhances children’s comprehension. We investigated whether adult prompting during the reading of an electronic book enhanced children’s understanding of a biological concept. Ninety-one 4-year-olds read about camouflage in 3 conditions. We varied how prompts were provided: (a) read by the book, (b) read by a researcher, or (c) given face to face by the researcher. There was an interaction between children’s initial vocabulary level and condition. Children with low vocabulary scores gave fewer camouflage responses …

What If Klein & Barron Are Right About Insect Sentience?, Bob Fischer

Animal Sentience

If Klein & Barron are right, then insects may well be able to feel pain. If they can, then the standard approach to animal ethics generates some implausible results. Philosophers need to develop alternatives to this framework to avoid them.

Subjective Experience And Moral Standing, Andy Lamey

Animal Sentience

Klein & Barron’s analysis focuses on the capacity for any subjective experience at all. It does not seek to demonstrate that insects can experience pleasure and pain in particular. This would be something of which insects have not traditionally been thought capable. If further research were to demonstrate that one or more insect species turn out to be conscious, yet incapable of experiencing pleasure and pain, it would give rise to a philosophical question that ethicists have yet to answer: Would a creature that is conscious, but lacks the capacity to feel pain, have moral standing?

Integrative Approach For Inference Of Gene Regulatory Networks Using Lasso-Based Random Featuring And Application To Psychiatric Disorders, Dongchul Kim, Mingon Kang, Ashis Kumer Biswas, Chunyu Liu, Jean Gao

Computer Science Faculty Publications

Background

Inferring gene regulatory networks is one of the most interesting research areas in the systems biology. Many inference methods have been developed by using a variety of computational models and approaches. However, there are two issues to solve. First, depending on the structural or computational model of inference method, the results tend to be inconsistent due to innately different advantages and limitations of the methods. Therefore the combination of dissimilar approaches is demanded as an alternative way in order to overcome the limitations of standalone methods through complementary integration. Second, sparse linear regression that is penalized by the regularization …

Exposing The “Shadow Side”: Female-Female Competition In Jane Austen’S Emma, Melissa M. Lyman

LSU New Orleans Theses and Dissertations

Many critics have examined the shifting nature of female friendship in Jane Austen’s Emma from cultural and historical angles. However, a comprehensive scientific analysis of female-female alliance and competition in the novel remains incomplete. The Literary Darwinist approach considers the motivations of fictional characters from an evolutionary perspective, focusing primarily on human cognition and behaviors linked to reproductive success, social control, and survival. While overt physical displays of male competition are conspicuous in the actions of the human species and those of their closest primate relatives, female aggression is often brandished psychologically and indirectly, which makes for a much more …

Neural Mechanisms Of Action Switching Moderate The Relationship Between Effortful Control And Aggression, Eric L. Rawls

LSU New Orleans Theses and Dissertations

Aggression and violence are social behaviors that exact a significant toll on human societies. Individuals with aggressive tendencies display deficits in effortful control, particularly in affectively charged situations. However, not all individuals with poor effortful control are aggressive. This study uses event-related potentials (ERPs) to decompose the chronology of cognitive functions underlying the link between effortful control and aggression. Specifically, this study investigates which ERPs moderate the effortful control - aggression association. We examined three successive ERP components (P2, N2 and P3) for stimuli that required effortful control. Results indicated that N2 activation, but not P2 or P3 activation, moderated …

Spice: A Software Tool For Studying End-User’S Insecure Cyber Behavior And Personality-Traits, Anjila Tamrakar

LSU New Orleans Theses and Dissertations

Insecure cyber behavior of end users may expose their computers to cyber-attack. A first step to improve their cyber behavior is to identify their tendency toward insecure cyber behavior. Unfortunately, not much work has been done in this area. In particular, the relationship between end users cyber behavior and their personality traits is much less explored. This paper presents a comprehensive review of a newly developed, easily configurable, and flexible software SPICE for psychologist and cognitive scientists to study personality traits and insecure cyber behavior of end users. The software utilizes well-established cognitive methods (such as dot-probe) to identify number …

Spatial Attention To Social Cues Is Not A Monolithic Process, Samuel M. Harding, Ty W. Boyer, Bennett I. Bertenthal

Psychology: Faculty Presentations (2009-2022)

Social stimuli are a highly salient source of information, and seem to possess unique qualities that set them apart from other well-known categories. One characteristic is their ability to elicit spatial orienting, whereby directional stimuli like eyegaze and pointing gestures act as exogenous cues that trigger automatic shifts of attention that are difficult to inhibit. This effect has been extended to non-social stimuli, like arrows, leading to some uncertainty regarding whether spatial orienting is specialized for social cues. Using a standard spatial cueing paradigm, we found evidence that both a pointing hand and arrow are effective cues, but that the …

Inducing Application Of Interdisciplinary Frameworks: Experiences From The Domains Of Information Literacy And Responsible Conduct Of Research, Anne E. Leonard, Jean E. Hillstrom

Publications and Research

Constructivist frameworks for information literacy and research ethics can be developed and nurtured in the context of an interdisciplinary course. Using the frameworks of two disciplines, students went on an experiential journey in support of ethics foundations through guest lectures and active learning exercises. This study describes the development and content of the responsible conduct of research and information literacy modules and discusses the role of each in an interdisciplinary course. Learning goals for both modules were evaluated by examining student responses in a free-writing exercise at the end of the semester, concluding with a discussion of the structural and …

Is Cortex Necessary?, Sean Allen-Hermanson

Animal Sentience

A key contention of Klein & Barron (2016) is that consciousness does not depend on cortical structures. A critical appraisal suggests they have overestimated the strength of their evidence.

Who Is A Person? Whoever You Want It To Be, Gwen J. Broude

Animal Sentience

Rowlands provides an expanded definition of personhood that preserves the requirement of unity of mental life from the orthodox definition but argues that implicit unity of mind is sufficient for conferring personhood. This allows more or all animals to be considered persons. Implicit unity of mind may be a bridge too far for those who endorse the orthodox account of personhood, and for good reasons. More fundamentally, who gets to decide what personhood entails or that personhood per se matters to such other issues as who receives legal or moral status and consideration? Perhaps we should worry less about definitions …

Associations Between Mental Health And Ebola-Related Health Behaviors: A Regionally Representative Cross-Sectional Survey In Post-Conflict Sierra Leone, Theresa S. Betancourt, Robert T. Brennan, Patrick Vinck, Tyler J. Vanderweele, Dayo Spencer-Walters, Joshua Jeong, Adeyinka M. Akinsulure-Smith, Phuong Pham

Publications and Research

Background

Little attention has been paid to potential relationships between mental health, trauma, and personal exposures to Ebola virus disease (EVD) and health behaviors in post-conflict West Africa. We tested a conceptual model linking mental health and trauma to EVD risk behaviors and EVD prevention behaviors.

Methods and Findings

Using survey data from a representative sample in the Western Urban and Western Rural districts of Sierra Leone, this study examines associations between war exposures, post-traumatic stress disorder (PTSD) symptoms, depression, anxiety, and personal EVD exposure (e.g., having family members or friends diagnosed with EVD) and EVD-related health behaviors among 1,008 …

Sensory Processing Specificity In Autism, Jannessa Kitchin

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

Currently, autism is defined at the behavioral level. Although much has been learned about the genetic, environmental, structural, and neuropsychological etiologies of autism much more research must be conducted to reach a full comprehensive definition of the disorder. At the behavioral level, a significant portion of individuals with autism have some level of sensory processing deficit, studies report 100% prevalence in this population. The goal of many researchers in the autism field is to identify how abnormal sensory response patterns differentiate this group from those with other developmental disorders as well as those who are typically developing. Findings show atypical …

Are Insects Sentient?, Michael Tye

Animal Sentience

I comment on the methodology used by Klein & Barron for dealing with the question of insect sentience and I briefly make a proposal of my own. Once it is granted that insects are sentient, a further question arises: which insects are subject to which states of sentience? Do insects feel pain, for example? If so, which ones? On the further question, I note, Klein & Barron have nothing to say.

Animal Grieving And Human Mourning, Matteo Colombo

Animal Sentience

King’s How animals grieve beautifully describes several ways in which animals and humans show a similar capacity for grief. Yet this book does not sufficiently emphasise the language-empowered capacity to objectify thinking and sentiments about death, which makes human mourning unique. Here I put this capacity into focus and relate it to the social-normative aspect of human mourning that seems to be missing in other animals.

Insects Join The Consciousness Fray, Bjorn H. Merker

Animal Sentience

Klein & Barron's review of recent insect neurobiology helps correct the impression that insect behavior is orchestrated without the benefit of central integrative mechanisms. Given their existence, the authors go on to ask whether these central mechanisms also feature the kind of integrative operations that support sentience, and propose that they do. Along the way they raise a number of conceptual and evidentiary issues of fundamental importance for the neuroscience of consciousness, allowing me to comment favorably on a number of them. I conclude by pointing to ways in which the conception of insect sentience they outline might be tested …

Positive Reappraisals After An Offense: Event-Related Potentials And Emotional Effects Of Benefit-Finding And Compassion, Justin C. Baker, John K. Williams, Charlotte Vanoyen-Witvliet, Peter C. Hill

Faculty Publications

Using a within subjects design, three emotion regulation strategies (compassion‐focused reappraisal, benefit‐focused reappraisal, and offense rumination) were tested for their effects on forgiveness, well‐being, and event‐related potentials (ERPs). Participants (N = 37) recalled a recent interpersonal offense as the context for each emotion regulation strategy. Both decisional and emotional forgiveness increased significantly for the two reappraisal strategies compared to offense rumination. Compassion‐focused reappraisal prompted the greatest increase in both decisional and emotional forgiveness. Furthermore, both reappraisal strategies increased positively oriented well‐being measures (e.g., joy, gratitude) compared to offense rumination, with compassion‐focused reappraisal demonstrating the largest effect on empathy. Late positive …

The Role Of Client Avoidance On Ptsd Recovery Throughout The Course Of Trauma Therapy, Chelsea Alyssa Gloth

Dissertations

The accumulation of randomized controlled trials (RCTs) for the treatment of posttraumatic stress disorder (PTSD) over the past few decades has contributed to the development of clinical treatment guidelines (Chambless & Ollendick, 2001; Forbes et al., 2010; Truax & Thomas, 2003). Two treatments that have gained substantial support are Prolonged Exposure (PE) and Cognitive Processing Therapy (CPT). Although these treatments result in most participants losing their PTSD diagnosis and obtaining meaningful reductions in symptoms, some clients remain refractory to treatment. Researchers have worked to identify predictors of treatment outcome, but have given minimal attention to aspects of client avoidance as …
