Cephalopod Complex Cognition, Jennifer Mather

Cognitive Ethology Collection

Cephalopods, especially octopuses, offer a different model for the development of complex cognitive operations. They are phylogenetically distant from the mammals and birds that we normally think of as ‘intelligent’ and without the pervasive social interactions and long lives that we associate with this capacity. Additionally, they have a distributed nervous system — central brain, peripheral coordination of arm actions and a completely separate skin appearance system based on muscle-controlled chromatophores. Recent research has begun to show how these apparently separate systems are coordinated. Learning and cognition are used toward prey, in antipredator actions and in courtship. These examples show …

The Role Of Personality Using The Millon College Counseling Inventory In Explaining A Variety Of Career Decision-Making Variables, Carly Chadick

Dissertations

In vocational research, the Five Factor Model (FFM) is one of the most popular theories of personality used when evaluating the role of personality in career development. However, thus far, few other personality theories have been used in vocational research, such as Millon’s theory. Therefore, the purpose of this study was to examine how Millon’s theory, operationalized using the Millon College Counseling Inventory (MCCI), may explain career development constructs, above the FFM traits, in a college student sample. Results indicated that the MCCI explained additional variance beyond FFM traits in several different career variables (i.e., profile elevation, negative career thinking, …

(Re)Grounding Grounded Theory: A Close Reading Of Theory In Four Schools, Tavis Apramian, Sayra Cristancho, Chris Watling, Lorelei Lingard

Health and Rehabilitation Sciences Publications

The debate over what counts as theory has dominated methodological conversations in grounded theory research for decades. Four of the schools of thought in that debate – Glaserian, Straussian, Charmazian, and Clarkeian – hold different assumptions about what theory is and how it is made. The first two schools understand theory as an abstraction that exactingly accounts for exceptions. The second two schools understand theory as a process of describing voices hidden from public view. While Glaserian and Straussian coding processes focus on coding exceptions, Charmazian and Clarkeian coding processes focus on building a story of the participants or social …

Effects Of Early Adolescent Exposure To D-Amphetamine In A Rodent Model Of Nicotine Reward, Eric Louis Harvey

Dissertations

Previous studies with rodents have found that adolescent exposure to psychoactive drugs can alter neurophysiology and produce behavioral effects that persist into adulthood. While several studies have examined the effects of adolescent exposure to nicotine on the subsequent rewarding value of various drugs of abuse in adulthood, to date, no known studies have examined the converse of this relationship. d-Amphetamine (i.e., dextroamphetamine, ProCentra®) is a potent psychostimulant that is commonly used in the treatment of Attention-Deficit/Hyperactivity Disorder (ADHD) in adolescents. The present study assessed the effects of adolescent exposure to d-amphetamine on the rewarding value of nicotine in …

Assessing The Impact Of Pain On Decision-Making In A Rat Gambling Task (Rgt), Celina Antionette Salcido

Psychology Theses - Archive

Recent clinical assessments using the Iowa Gambling Task have revealed pain can negatively affect decision-making processes, leading to risky or poor decisions. Despite the gain these models have made in further elucidating the cognitive components of pain, they fail to fully address neurobiological factors of decision-making on behavior. As a result, there remains significant limitation in assessing the extent of how acute or chronic pain and the relief of pain with analgesics can affect cognitive abilities. Therefore, we examined the effect of acute and chronic pain on decision processing and the impact of morphine on that decision processing. In this …

Regulating Anger Under Stress Via Cognitive Reappraisal And Sadness, Jun Zhan, Xiaofei Wu, Jin Fan, Jiayou Guo, Jianshe Zhou, Jun Ren, Chang Liu, Jing Luo

Publications and Research

Previous studies have reported the failure of cognitive emotion regulation (CER), especially in regulating unpleasant emotions under stress. The underlying reason for this failure was the application of CER depends heavily on the executive function of the prefrontal cortex (PFC), but this function can be impaired by stress-related neuroendocrine hormones. This observation highlights the necessity of developing selfregulatory strategies that require less top-down cognitive control. Based on traditional Chinese philosophy and medicine, which examine how different types of emotions promote or counteract one another, we have developed a novel emotion regulation strategy whereby one emotion is used to alter another. …

Rocs In Eyewitness Identification: Instructions Vs. Confidence Ratings, Laura Mickes, Travis M. Travis M. Seale-Carlisle, Stacy A. Wetmore, Scott D. Gronlund, Steven E. Clark, Curt A. Carlson, Charles A. Goodsell, Dawn R. Weatherford, John T. Wixted

Psychology Faculty Publications (Archived)

From the perspective of signal-detection theory, different lineup instructions may induce different levels of response bias (Clark, 2005). If so, then collecting correct and false identification rates across different instructional conditions will trace out the ROC – the same ROC that, theoretically, could also be traced out from a single instruction condition in which each eyewitness decision is accompanied by a confidence rating. We tested whether the two approaches do in fact yield the same ROC. Participants were assigned to a confidence rating condition or to an instructional biasing condition (liberal, neutral, unbiased, or conservative). After watching a video of …

Sex Differences In Serotonergic And Dopaminergic Mediation Of Lsd Discrimination In Rats, Keli A. Herr

Dissertations

After decades of opposition, a resurgence of interest in the psychotherapeutic potential of LSD is gaining acceptance in the medical community. Future acceptance of LSD as a psychotherapeutic adjuvant may be predicated on knowledge about its neural mechanisms of action. Preclinical drug discrimination assay offers an invaluable model to determine the neural mechanisms underlying LSD’s interoceptive stimulus effects. Unfortunately, current preclinical literature on LSD discrimination is based on results obtained exclusively in male subjects. The present study represents the first known preclinical assessment of possible sex differences in the discriminative stimulus effects of LSD.

Adult female (n=8) and male (n=8) …

The Transformative Power Of Deliberate Creativity: Reflections Of A Priest Creativity Practitioner, Felix-Kingsley Nnamdi Obialo

Creativity and Change Leadership Graduate Student Master's Projects

The idea of creativity continues to gain global currency as the tool for growth and development, especially in our contemporary world. There is an emerging universal paradigm shift that promotes creativity as something that could be structured and deliberate as against the erstwhile belief that it is restricted and by chance. Nevertheless, some individuals, groups, and climes are yet to fully embrace creativity in all its ramifications. Creativity practice is one of the means to foster and sustain creativity in persons and groups. Consequently, nurturing creativity continues to impact people and contexts. Through four case studies, this project presents a …

Evaluating The Effects Of "On-Task In A Box" As A Class-Wide Intervention For Increasing On-Task Behavior And Academic Performance, Allison Ashley Battaglia

Dissertations

The present study was designed to replicate and extend the literature on the intervention package, On-Task in a Box, as a class-wide intervention to increase on-task behavior and decrease disruptive behavior. A second purpose of the study was to evaluate the effects of the intervention on students’ academic performance. The On-Task in a Box intervention utilized video modeling to train students on how to engage in on-task behavior, as well as how to self-monitor their behavior. Additionally, the intervention included students self-monitoring their on-task behavior using self-recording forms. Depending on select students’ percentage of on-task behavior on the self-recording forms, …

An Evaluation Of Behavioral Skills Training On The Implementation Of Peer-Mediated Discrete Trial Training, Christopher M. Furlow

Dissertations

The purpose of this study was to evaluate the effects of behavioral skills training on the implementation of an evidence-based teaching method by student interventionists for children with autism spectrum disorder (ASD). Three elementary school students were trained to use an applied behavior analysis (ABA) based instructional method, known as discrete trial training (DTT), to teach academic skills to children with ASD. A multiple baseline across individuals was used to demonstrate the effectiveness of the behavioral skills training and peer-mediated DTT procedures. Generalization of the interventionist’s ability to teach new, previously untrained target behaviors was assessed by conducting generalization probes …

Tootling With A Randomized Independent Group Contingency In A High School Setting, John Dylan Ken Lum

Dissertations

Tootling is a procedure where students report their classmates’ positive and prosocial behavior. The present study examined the effects of tootling on students’ disruptive and academically engaged behavior in three general education high school classrooms. An A-B-A-B withdrawal design was used to assess the effects of the intervention. Students wrote tootles anonymously on paper slips and placed them into a marked container. Unlike previous tootling studies, a randomized independent group contingency procedure was used to reward the students to reduce the number of steps required to implement the intervention. At the end of the class period, teachers randomly drew three …

Exploring The Relationship Between Physical Activity And Executive Function In Early Childhood Populations: An Investigation Of Maternal Encouragement Of Activity, Lauren P. Driggers-Jones

Electronic Theses and Dissertations

Researchers have found positive associations between physical activity and executive function in adolescence and adulthood. However, research in early childhood has revealed only negative relationships. In the present study, I explored whether maternal encouragement of physical activity might moderate this relationship in very young children. Using video recordings from an archival dataset, eight maternal encouragement measures were derived from mother-child free play sessions. Although it was expected that maternal encouragement of child activity would broadly play a moderating role in the relationship between children’s physical activity and their executive function, only maternal questions seemed to moderate this relationship. One explanation …

The Good Behavior Game: Effects On And Maintenance Of Behavior In Middle-School Classrooms Using Class Dojo, Komila Dadakhodjaeva

Dissertations

Classroom management is one of the key components for successful instruction and affects both instructors and learners. Although most frequent discipline strategies in schools involve punitive actions, research suggests that using positive statements to teach and reinforce desirable behaviors is more appropriate and effective. A form of a group-oriented contingency that focuses on desirable behaviors is a positive variation of the Good Behavior Game (GBG). The GBG has been used widely in its original form, focusing on undesirable behaviors, and more research is needed on its positive version. Another strategy that can be used within classrooms is Class Dojo, a …

Do Eye Movements During Shape Discrimination Reveal An Underlying Geometric Structure?, Bradley R. Sturz, Ty W. Boyer, John F. Magnotti, Kent D. Bodily

Psychology: Faculty Publications

Using a psychophysical approach coupled with eye-tracking measures, we varied length and width of shape stimuli to determine the objective parameters that corresponded to subjective determination of square/rectangle judgments. Participants viewed a two-dimensional shape stimulus and made a two-alternative forced-choice whether it was a square or rectangle. Participants’ gaze was tracked throughout the task to explore directed visual attention to the vertical and horizontal axes of space. Behavioral results provide threshold values for two-dimensional square/rectangle perception, and eye-tracking data indicated that participants directed attention to the major and minor principal axes. Results are consistent with the use of the major …

Value Co-Creation Propositions: A Self-Determination Theory Of Customer Acceptance, Trust And Wellbeing, Lenna V. Shulga

UNLV Theses, Dissertations, Professional Papers, and Capstones

With the emergence of shared business models, hospitality and tourism consumers are faced with the decision to accept value propositions from various service providers, including traditional, collaborative and shared. Grounded in service-dominant logic, theory of acceptance, theory of value, self-determination theory and generational theory, this dissertation examines why consumers accept value propositions from service providers and what drives customers to collaborate with front-line employees. The research uses three studies that utilized a destination resort context with a mixed factorial equal cells experimental design. Study 1 utilized a 3 (generations) x 3 (business models) x 4 (value propositions) factorial between-within subjects …

Developmental Trajectories Of Executive And Verbal Processes In Children With Phenylketonuria, Zoe Hawks

Arts & Sciences Graduate Student Theses and Dissertations

Phenylketonuria (PKU) is a recessive disorder characterized by disruption in the metabolism of the amino acid phenylalanine. Using a verbal fluency task, previous studies demonstrated that word production is reduced in individuals with PKU relative to controls. Beyond word production, verbal fluency output can be scored for clustering and switching, which enable characterization of verbal and executive processes, respectively. The present study is the first to evaluate clustering and switching in PKU within a longitudinal design, thereby elucidating the developmental time course of core cognitive processes. To this end, semantic (animals, food/drink) and phonemic (S words, F words) fluency data …

Visual And Olfactory Recognition Of Familiar Humans And Elephants By African Elephants, Victoria Perret

Masters Theses and Doctoral Dissertations

African elephants (Loxodonta africana) distinguish between familiar and non-familiar conspecifics through olfaction and human ethnic groups through vision and olfaction. We investigated whether elephants recognize individual familiar humans and elephants through vision and olfaction in two captive African elephants. After training, visual recognition was tested over three sessions with three keepers holding a photo array with two photos. Using similar methodology, olfactory recognition was assessed using a t-shirt worn by an individual as the sample above the photo array. Visual recognition of familiar elephants was assessed matching a photo of one side of a familiar elephant to a photo array …

How Adults In Developmental Reading Courses Describe Their Educational Life Experiences: A Phenomenological Case Study Examining Whether Experiences Influence Reading Attitudes And Decision-Making Processes, Ashley Paige Reece Armour

Doctoral Dissertations and Projects

The purpose of this phenomenological case study is to explore the reading attitudes and decision-making skills of college freshmen enrolled in remedial language arts courses. The theoretical framework guiding this study is qualitative phenomenology explained by Baxter and Jack (2008). This specific type of research “provides tools for researchers to study complex phenomena within their contexts” and the findings help researchers evaluate program, design, and intervention methods, which is pertinent to the discovery of prevailing reading attitudes among struggling students and allows researchers to prevent, adjust, and improve these attitudes in future students (Baxter and Jack, 2008; Yin, 2003). This …

Cognitive Demand And The Outcome Density Effect, Ciara Louise Willett

Seton Hall University Dissertations and Theses (ETDs)

Judgments regarding the strength of a cause to produce an outcome do not always follow predictions of normative causal reasoning models (Kao & Wasserman, 1993). In the case of the outcome density effect, individuals’ ratings of the strength of a putative cause tend to be greater when the number of observed outcomes is high than when it is low (e.g. Jenkins & Ward, 1965). In the current experiment, I investigated the outcome density effect as a possible heuristic. Participants made causal judgments based on information about the prevalence of headaches in a sample of individuals who did or did not …

Vasopressin And Oxytocin Reduce Food Sharing Behavior In Male, But Not Female Marmosets In Family Groups, Jack H. Taylor, Allison A. Intorre, Jeffrey A. French

Psychology Faculty Publications

Oxytocin (OT) is critical for lactation and maternal care, but OT and the related nonapeptide vasopressin are important for caregiving behaviors in fathers and alloparents as well. This experiment tested the effects of vasopressin and OT on food sharing in marmoset families. We treated caregivers (parents, siblings) with intranasal vasopressin, OT, or saline, and then paired them with the youngest marmoset in the family. Caregivers were given preferred food, and then observed for food sharing and aggressive behavior with young marmosets. OT reduced food sharing from male alloparents to youngest siblings, and fathers that received vasopressin refused to share food …

Combat Experiences, Iso-Strain, And Sleep Quality Affect Symptoms Of Posttraumatic Stress Among Working Post-9/11 Veterans, Gilbert Patrick Brady Jr.

Dissertations and Theses

Despite the growing need, prior research on how the civilian work domain may affect posttraumatic stress is scarce. Moreover, few if any studies have investigated how perceptions of one's job and insomnia may shape traumatic stress symptoms, post-combat. Presently, about 4 million Americans have served in the "Global War on Terrorism," including nearly 1 million reservists. By contrast, 8.7 million Americans served in the Vietnam War: over twice the number of U.S. military personnel who have fought since 9/11. Surprisingly, combat experiences alone do not explain the majority of posttraumatic stress disorder cases, even after multiple deployments, suggesting the presence …

Social Context-Dependent Activity In Marmoset Frontal Cortex Populations During Natural Conversations, Samuel U. Nummela, Vladimir Jovanovic, Lisa De La Mothe, Cory T. Miller

Psychological Sciences and Counseling Faculty Research

Communication is an inherently interactive process that weaves together the fabric of both human and nonhuman primate societies. To investigate the properties of the primate brain during active social signaling, we recorded the responses of frontal cortex neurons as freely moving marmosets engaged in conversational exchanges with a visually occluded virtual marmoset. We found that small changes in firing rate (∼1 Hz) occurred across a broadly distributed population of frontal cortex neurons when marmosets heard a conspecific vocalization, and that these changes corresponded to subjects' likelihood of producing or withholding a vocal reply. Although the contributions of individual neurons were …

An Investigation Of The Neural Components And Saccade Sequences That Enable Direct Navigation Through Virtual Space, Daniel R. Barto

Psychology ETDs

Spatial navigation is a critical behavior for nearly all life forms. The ability to navigate to a destination and to remember how to return to that destination involves numerous brain processes such as perception, attention, memory, learning, proprioception, and distance estimation. The study of spatial navigation, in various organisms and on different sorts of maze-apparatuses, has revealed what is required of the brain and what is required of the environment to enable successful navigation. This dissertation adds to this vast literature by examining the physiological and behavioral components involved in human navigation in a virtual environment.

The primary aim of …

Bonds Beyond Time: Are There Differences In Well-Being, Autonomy, And Bond Between Visually Impaired Individuals With Guide Dogs Versus Pet Dogs?, Nicole Yarmolkevich

Theses and Dissertations

Well-being is a broad umbrella term that encompasses an individual’s appraisal of situations and events and their satisfaction with life (Diener, 1994). Research has shown that having a severe disability can negatively impact a person’s sense of well-being. Specifically, research has shown that individuals with visual impairments have a lower well-being because they feel like they are not as independent, they have many obstacles in their way, and they feel as if they are a bother to everyone around them (Lopez-Gusticia & Cordoba, 2008). To combat these obstacles, people with visual impairments opt to get a guide dog to help …

Microglia Density Decreases In The Rat Rostral Nucleus Of The Solitary Tract Across Development And Increases In An Age-Dependent Manner Following Denervation, Andrew J. Riquier, Suzanne I. Sollars

Psychology Faculty Publications

immune response to injury, and are implicated in facilitating neural plasticity. The rodent gustatory system is highly plastic, particularly during development, and outcomes following nerve injury are more severe in developing animals. The mechanisms underlying developmental plasticity in the taste system are largely unknown, making microglia an attractive candidate. To better elucidate microglia’s role in the taste system, we examined these cells in the rostral nucleus of the solitary tract (rNTS) during normal development and following transection of the chorda tympani taste nerve (CTX). Rats aged 5, 10, 25, or 50 days received unilateral CTX or no surgery and were …

Normal Behavioral Responses To Light And Darkness And The Pupillary Light Reflex Are Dependent Upon The Olivary Pretectal Nucleus In The Diurnal Nile Grass Rat, Andrew J. Gall, Ohanes S. Khacherian, Brandi Ledbetter, Sean P. Deats, Megan Luck, Laura Smale, Lily Yan, Antonio A. Nunez

Faculty Publications

The olivary pretectal nucleus (OPT) is a midbrain structure that receives reciprocal bilateral retinal projections, is involved in the pupillary light reflex, and connects reciprocally with the intergeniculate leaflet (IGL), a retinorecipient brain region that mediates behavioral responses to light pulses (i.e., masking) in diurnal Nile grass rats. Here, we lesioned the OPT and evaluated behavioral responses in grass rats to various lighting conditions, as well as their anxiety-like responses to light exposure. While control grass rats remained diurnal, grass rats with OPT lesions exhibited a more night-active pattern under 12h:12h light-dark (LD) conditions. However, when placed in constant darkness, …

The Effect Of Androstenone As A Mating Prime On Drinking And Approach Behavior, Robin Tan

USF Tampa Graduate Theses and Dissertations

Recent research has shown that sexual activity may be influenced by variables suggested by evolutionary theory, such as pheromonal cues. A recent study in our laboratory indicated that female pheromones influence men’s drinking and approach behavior based on hidden pathways of behavioral influence caused by chemosensory signals. The current study sought to examine whether a link exists between male pheromones and women’s drinking and approach behavior, through the use of a possible male sex pheromone called androstenone, and sought to examine this link within the context of a women’s ovulation cycle. One hundred and three female participants were primed with …

Impacting Student Slumber: An Analysis Of Self-Report And Physiological Data Following A Psychoeducational Intervention, Danielle N. Newman

Doctoral Dissertations

Research shows that college students have extensive rates of sleep struggles, with up to 89% of college students reporting that they have moderate to severe difficulties with sleep (Buboltz, Brown, & Soper, 2001). Insufficient sleep has been linked to problems with academics (Kelly, Kelly, & Clanton, 2001; Taylor, Vatthauer, Bramoweth, Ruggero, & Roane, 2013), mental health (Ghumman & Barnes, 2013; Home, 1993; Manber & Chambers, 2009), physical health (Dahl & Lewin, 2002; Gailliot et al., 2007; Lyytikainen, Rahkonen, Lahelma, & Lallukka, 2011; Van Cauter, Leproult, & Plat, 2000), and a variety of other problems. Results pertaining to the suggested and …

Behavioral And Pharmacological Validation Of An Integrated Fear-Potentiated Startle And Prepulse Inhibition Paradigm, Mengjiao Zhang, Ming Li

Department of Psychology: Faculty Publications

Fear-potentiated startle (FPS) and prepulse inhibition (PPI) of acoustic startle are two widely used paradigms specifically designed to capture the impact of negative emotion (e.g. fear) and preattentive function on startle response. Currently, there is no single paradigm that incorporates both FPS and PPI, making it impossible to examine the potential interactions between fear and attention in the regulation of startle response. In this study, we developed an integrated FPS and PPI test protocol and validated it with psychoactive drugs. In Experiment 1, male Sprague-Dawley rats were randomly assigned to one of five groups, receiving either Light -Shock conditioning trials, …
