The Temporal Nature Of The Acute Stress Response And Its Impact On Explicit Learning, Steven B. Hutchinson

Electronic Theses and Dissertations

Acute stress is commonly experienced by many throughout their lives. Given the demanding lifestyle of many career paths, it's important to gauge the influence of these stressors upon cognitive performance. The present dissertation focus' upon explicit learning in attempts to explore one avenue of the stress-cognition relationship. The Trier Social Stress Test (TSST) was used as a lab stressor for Experiments 1 and 2, in which participants are asked to give a speech and complete a difficult math task in front of 2 evaluators trained to monitor non-verbal behavior. Experiment 1 investigates the dynamic stress response during the minutes following …

Humans Integrate Monetary And Liquid Incentives To Motivate Cognitive Task Performance, Debbie Yee

Arts & Sciences Electronic Theses and Dissertations

It is unequivocal that a wide variety of incentives can motivate behavior. However, few studies have explicitly examined whether and how different incentives are integrated in terms of their motivational influence. The current study examines the combined effects of monetary and liquid incentives on cognitive processing, and whether appetitive and aversive incentives have distinct influences. We introduce a novel task paradigm, in which participants perform cued task-switching for monetary rewards that vary parametrically across trials, with liquid incentives serving as post-trial performance feedback. Critically, the symbolic meaning of the liquid was held constant (indicating successful reward attainment), while liquid valence …

Mathematical Modeling Of Stress Management Via Decisional Control, Matthew J. Shanahan

Electronic Thesis and Dissertation Repository

Engaging the environment through reason, humankind evaluates information, compares it to a standard of desirability, and selects the best option available. Stress is theorized to arise from the perception of survival-related demands on an organism. Cognitive efforts are no mere intellectual exercise when ontologically backed by survival-relevant reward or punishment. This dissertation examines the stressful impact, and countervailing peaceful impact, of environmental demands on cognitive efforts and of successful cognitive efforts on a person’s day-to-day environment, through mathematical modeling of ‘decisional control’. A modeling approach to clinical considerations is introduced in the first paper, “Clinical Mathematical Psychology”. A general exposition …

The Embodied Causal Learner, Vanja Vlajnic

Seton Hall University Dissertations and Theses (ETDs)

Traditionally, cognitive psychology has assumed a disembodied learner and thinker. However, an emerging approach known as embodiment posits that seemingly irrelevant motor or perceptual aspects of a task can affect higher-level cognition. The findings from such embodiment studies have also been shown to extend into real-world settings. For example, children who were taught mathematical concepts while required to make gestures consistent with the problem’s solution were more likely, on average, to apply the mathematical concepts correctly in the future (Cook, Mitchell, & Goldin-Meadow, 2008). For this specific study, the area of causal learning was examined.

The primary goal of this …

The Effects Of Size And Principal Axis Difference Ratio On The Use Of Featural And Geometric Cues, Spencer J. Price

Honors College Theses

Enclosure size has been shown to affect an animal’s reliance on featural and geometric cues when reorienting in space. Previous research has shown that humans and animals rely primarily on geometric cues in smaller enclosures, and on featural cues in larger enclosures. The multiple-bearings hypothesis predicts that directional information is more discriminable than distance information when landmarks are father away from a goal. As the size of the environment increased, the distance information was less discernible than featural information. In the current study, we tested to see if the reliance on geometry changes across enclosure size. Three different Principal Axis …

Transitioning Into Adulthood: Exploring The Educational Trajectories Among Undocumented Latinos, Michelle G. Parisot

Theses and Dissertations

The following qualitative study used semi-structured qualitative interviews to investigate the educational trajectories of five undocumented Latinos who were either in the process of transitioning into a college program or had recently enrolled in a college program. An initial interview was conducted with each of the participants followed by a follow-up interview about 3-months after the initial interview was conducted. A Participatory Action Research (PAR) approach was used to carry out this research study. Therefore, collaboration with participants and key community members was essential throughout the entire research process. A research team was created to perform thorough data analysis and …

The Effects Of Mindfulness On Verbal Distress Disclosure, Sara Fleming

USC Aiken Psychology Theses

The purpose of this study was to investigate the effect of a mindfulness induction on participants’ verbal distress disclosure (as measured by the Linguistic Inquiry and Word Count and State Disclosure Questionnaire). Participants were 86 undergraduate students enrolled in an Introduction to Psychology course and were randomly assigned to one of two conditions: a mindfulness condition or a control condition. Participants in the mindfulness condition engaged in a 15-minute mindfulness induction prior to disclosing about a stressful experience, while participants in the control condition listened to a neutrally valenced audio excerpt from a podcast about emotions before speaking about a …

An Examination Of The Relationship Between Psychological Distress And Risky Sexual Behaviors Among A Treatment-Seeking Opioid-Dependent Population, Hayley M. Smith

USC Aiken Psychology Theses

Substance abusing populations are at an increased risk for disease transmission and have higher rates of psychological comorbidity compared to the general population (e.g., Centers for Disease Control and Prevention [CDC], 2012a; Chaudhury & Singh, 2009; Des Jarlais, Semaan, & Arasteh, 2011; Goodwin & Stein, 2013). Numerous studies have implicated the interaction of psychological distress and risky sexual behaviors in the increased risk of disease transmission, however, several studies have not found this association. It has been suggested that there may be curvilinear relationship between psychological distress and risky sexual behaviors but this theory has yet to be tested. The …

On The Evolutionary Origins Of Religious Belief, Robert Duane Howard

Graduate Theses and Dissertations

Religious belief is a byproduct of evolutionarily designed cognitive mechanisms. The ubiquity of religious belief and experience across human cultures is explained by our common human psychology; our domain-specific cognitive mechanisms give rise, collectively, to the phenomenon of byproduct religious belief/experience. In this thesis, I will examine what I call religion-generating cognitive mechanisms, and I will argue that byproduct raw god-beliefs are developed by cultures into refined god-beliefs. These refined god-beliefs are co-opted by evolutionary processes and are cultural adaptations. My conception of “religious belief” in terms of raw and refined god-beliefs allows a disambiguation of the term “religion,” and …

The Role Of Sharing And Information Type In Children's Categorization Of Privileged And Conventional Information, Helana Girgis

Graduate Theses and Dissertations

Categorization is an essential part of our daily lives and an integral part of humans’ ability to function and interact within society. There are large bodies of research that document children’s categorization in domains such as natural kinds, artifacts and human kinds. One domain that has not been investigated is children’s ability to categorize different types of information; specifically conventional information, shareable to others with no restrictions, and privileged information, shareable to only a few. Study 1 investigated 4- and 5-year-olds and adults’ ability to categorize conventional and privileged information. All participants correctly categorized both types of information equally well …

Interrupting The Conspiracy Of Silence: Historical Trauma And The Experiences Of Hmong American Women, Ia Xiong

Theses and Dissertations

The Hmong have endured a history of oppressive and traumatic experiences. The Secret War was particularly significant as it resulted in genocide, dislocation, and oppression for the Hmong. In addition, the Hmong experience and their involvement as U.S. allies remained largely a secret for several decades. Current research suggests that Hmong Americans experience a high prevalence of mental health issues including depression, anxiety, and substance abuse as well as other health disparities. The purpose of this project was to explore how a history of massive group trauma and secrecy maintained about the Hmong may contribute to the current conditions of …

Memory Deficits In Older Adults: Evaluating Spaced Retrieval With Multiple Probe Techniques, Christopher Walmsley

Dissertations

Difficulties in recognizing and remembering the names of individuals are a common behavioral symptom of major neurocognitive disorder. A number of behavioral strategies have been proposed to improve memory deficits, including spaced retrieval, an intervention that emphasizes delayed recall of target information. Unfortunately, many of the studies that report beneficial effects of spaced retrieval use a very limited range of outcome measures, thus calling into question the magnitude and generality of any reported memory improvement. This study reports on the impact of spaced retrieval using four older adults with cognitive impairment living in an assisted living facility. All participants demonstrated …

Olfactory Enrichment In California Sea Lions (Zalophus Californianus), Mystera M. Samuelson

Dissertations

In the wild, California sea lions (Zalophus californianus) are exposed to a wide array of sensory information at all times. However, it is impossible for captive environments to provide this level of complexity. Therefore unique procedures and practices are necessary for the maintenance of physiological and psychological health in captive animals (Wells, 2009). This project aims to explore the behavioral effect of scent added to the environment, with the goal of improving the welfare of captive sea lions by introducing two scent types: 1.) Natural scents, found in their native environment, and 2.) Non-natural scents, not found in …

Audible Voice In Context, Airlie S. Rose

Doctoral Dissertations

The term audible voice refers to the sound of the text experienced by the reader during silent reading. It was coined by Elbow in his Landmark Essays to help the field of composition wrestle more productively with the concept of voice in writing. In this dissertation, voice is not a metaphor. Drawing on contemporary work in psycholinguistics, cognitive psychology, and consciousness studies, it examines the phenomenon of audible voice as a form of inner speech[1]. The premise of this study is that the experience of audible voice by the reader is a unique intersection of the individual's inner landscape …

Perceptions, Stereotypes And Cognitive Resources Of Female Businesspersons: A Social Identity Approach, Amy J. Y. Lim

Dissertations and Theses Collection (Open Access)

According to the Stereotype Content Model (SCM), female businesspersons are often stereotyped and labeled either as a Career Women, competent but cold, or as a Traditional Women, warm but incompetent. This suggests that female businesspersons are generally perceived to be either competent or warm individuals, but not both. However, this may not reflect female businesspersons’ own perceptions of their competence and warmth in the workplace. Contrary to the stereotypes, evidence has demonstrated that some female businesspersons display behaviors that signal both competence and warmth. Employing a social identity approach, I propose that gender-professional identity integration (G-PII), an individual difference that …

Support For Gestalt Versus Business-As-Usual Theories Of Insight Depends On Operational Definition Of Insight, Kimberly D. Lee

Psychology Theses & Dissertations

Some theories propose that insight involves automatic processes that are responsible for restructuring. Other theories postulate that the mechanisms surrounding restructuring are controlled and effortful. The current study tested these theories by comparing different methodology and operational definitions that have been used in previous research to investigate the nature of “Aha!” experiences and impasse in insightful problem solving. One hundred two undergraduate psychology students from Old Dominion University completed working memory tasks, six classic insight problems, and gave initial problem representation ratings for the insight problems before solution attempt. Using a think-aloud protocol, we assessed the occurrence of impasse during …

Variability, Stability, And Flexibility In The Speech Kinematics And Acoustics Of Adults Who Do And Do Not Stutter, Eric S. Jackson

Dissertations, Theses, and Capstone Projects

It is well known that people who do and do not stutter produce speech differently, at least some of the time, even when perceived as fluent. One way that investigators have assessed these differences is by measuring variability, or the inconsistency of repeated speech movements. Variability in speech has typically been quantified using linear analysis techniques (e.g., measures of central tendency), and results have indicated that people who stutter produce speech that is (sometimes) characterized by increased variability. However, variability is a complex phenomenon, one that cannot be assessed by linear methods alone. This dissertation employs linear and nonlinear analysis …

Art As Communication: Employing Gricean Principles Of Communication As A Model For Art Appreciation, Melissa June Dolese

Dissertations, Theses, and Capstone Projects

Abstract

How and why artworks elicit varied preferences and judgments among different individuals remains a topic with many unresolved issues. For instance, individuals with little artistic experience tend to show little appreciation for abstract art, even though such works often show a highly skilled organization of visual elements. A key aspect of a positive aesthetic experience concerns the ability of viewers to construct meaning. I propose that viewers attempt to make meaning of artworks due to a sense that art is a communicative process. Here I attempt an application of one intentionalist model of communication, the Gricean framework, to visual …

Roles Of Shifting Attention, Alternating Attention And Inhibition On Temporary Syntactic Ambiguity Resolution And Use Of Context In Younger And Older Adults, Youngmi Park

Dissertations, Theses, and Capstone Projects

Twenty-four younger adults (20-35 years, mean: 25.88) and thirty-four older adults (65-79 years, mean: 71.82) read sentences via a word-by-word self-paced reading paradigm. Study 1 examined how older and young adults resolve sentences containing Noun Phrase (NP) and Verb Phrase (VP)-attached Prepositional Phrases (PPs) yielding temporary syntactic ambiguity, and which cognitive factors (working memory capacity, inhibition, shifting attention, alternating attention, and cognitive processing speed) contribute to temporary syntactic ambiguity resolution.

Study 2 was designed to investigate how both age groups utilize contextual information while resolving PP-attachment, and which cognitive functions play a role in the use of referential context during …

The Role Of Posterior Parietal Cortex In Episodic Memory Retrieval: Transcranial Direct Current Stimulation Studies (Tdcs), Denise Pergolizzi

Dissertations, Theses, and Capstone Projects

Neuroimaging studies of recognition memory have shown that greater activity in the lateral posterior parietal cortex (PPC) correlates with successful recognition in a variety of paradigms, but experimental techniques that manipulate brain activity are necessary to determine the specific contribution of the PPC in episodic memory retrieval. Transcranial Direct Current Stimulation (tDCS) is a non-invasive technique that can be used to manipulate cortical excitability. The collection of experiments that comprise this dissertation use tDCS to determine: 1) whether or not the lateral PPC is causally involved in episodic retrieval, and 2) whether the lateral PPC has a direct role in …

Effects Of Nicotine On A Translational Model Of Working Memory, David Alderson Macqueen

USF Tampa Graduate Theses and Dissertations

Cognitive research with human non-smokers has demonstrated that nicotine generally enhances performance on tasks of attention but, working memory does not appear to be affected. In contrast, nicotine has been shown to produce robust enhancements of working memory in non-human animals. To address this disparity, the present study investigated the effects of nicotine (2mg, 4mg nicotine gum, and placebo) on the performance of 30 non-smokers (15 male) completing a working memory task developed for rodents (the odor span task, OST). Nicotine has been reported to enhance OST performance in rodents and the present study sought to determine whether the effect …

Toward A Two-Stage Model Of Free Categorization, Gregory J. Smith

Electronic Theses, Projects, and Dissertations

This research examines how comparison of objects underlies free categorization, an essential component of human cognition. Previous results using our binomial labeling task have shown that classification probabilities are affected in a graded manner as a function of similarity, i.e., the number of features shared by two objects. In a similarity rating task, people also rated objects sharing more features as more similar. However, the effect of matching features was approximately linear in the similarity task, but superadditive (exponential) in the labeling task. We hypothesize that this difference is due to the fact that people must select specific objects to …

Distance Effects In Similarity Based Free Categorization, Benjamin Alan Miller

Electronic Theses, Projects, and Dissertations

This experiment investigated the processes underlying similarity-based free categorization. Of particular interest was how temporal distance between similar objects affects the likelihood that people will put them into the same novel category. Participants engaged in a free categorization task referred to as binomial labeling. This task required participants to generate a two-part label (A1, B1, C1, etc.) indicating family (superordinate) and species (subordinate) levels of categorization for each object in a visual display. Participants were shown the objects one at a time in a sequential presentation; after labeling each object, they were asked to describe the similarity between that …

Prosody: An Important Cue To Word Learning, Monica Dasilva

Electronic Thesis and Dissertation Repository

Infants rely on cues from their environment during language acquisition. Prosodic features of words are one such cue and involve changes in stress and rhythmic patterns within speech. Studies have examined prosody’s influence on word segmentation and have found it to be a useful cue for detecting word boundaries (Johnson & Seidl, 2009). What is less understood is how prosody helps infants form associations between novel labels and their referents during word learning. The present thesis investigated the influence of prosodic cues on word learning. The looking times were recorded of 13 infants (19-25 months) exposed to object-label pairings that …

Estrogen-Sensitive Learning Is Not Affected By Combination Ethinyl Estradiol And Levonorgestrel Oral Contraceptive Use, Darlene F. Ficco

Doctoral Dissertations

Two studies were conducted to explore the cognitive effects of combination ethinyl estradiol and levonorgestrel contraceptive use during late adolescence and young adulthood. Three groups of females, naturally cycling, active pill phase, and hormone-free interval phase, were tested on a battery of estrogen-sensitive, i.e., place learning and word generation, and estrogen-insensitive, i.e., map drawing, mental rotation, digit span, story recall, and object recall, tasks. Study 2 was conducted as a means to replicate the findings observed in Study 1 and to manipulate task difficulty and sensitivity. Two measures of mood were administered, and salivary estradiol levels at time of testing …

The Coffee Shop Effect: Investigating The Relationship Between Ambient Noise And Cognitive Flexibility, Emily G. Nielsen

Electronic Thesis and Dissertation Repository

Cognitive flexibility is the ability to think diversely in order to solve problems and learn concepts. It has also been suggested that cognitive flexibility supports creativity. Research has demonstrated that creativity is enhanced by moderate volumes of ambient noise. This thesis sought to replicate and extend this line of research by investigating how noise affects cognitive flexibility. Study 1 assessed the effects of noise on three creativity tasks. Performance was found to be enhanced by ambient noise, particularly among those who listen to music while they study/work. Study 2 examined how noise affects performance on a category learning task designed …

Breaking Apart The Reinforcement Learning Deficit In Schizophrenia, Adam Culbreth

Arts & Sciences Electronic Theses and Dissertations

Reinforcement learning deficits have long been associated with schizophrenia. However, tasks traditionally used to assess these deficits often rely on multiple processing streams leaving the etiology of these task deficits unclear. In the current study, we borrowed a recent framework from computational neuroscience, which separates reinforcement-learning into two distinct systems, model-based and model-free. Under this framework, the model-free system learns about the value of actions in the immediate context, while the model-based system learns about the value of actions in both immediate and subsequent states that may be encountered as a result of their actions. Using a decision task that …

Culture And Cognition: The Role Culture Plays In Cognitive Development In Rural Tanzania, Eileen Seissen

Capstone Collection

This capstone paper examines the perceived difference of cognition in a Tanzanian classroom. It also examines the effects culture has on cognition. It aims to answer the questions: What role does Tanzanian culture play in shaping the cognitive skills of its children? And, from an American trainers perspective, within an experiential learning environment, what cognitive differences are perceived in abstract thinking, creativity, critical thinking, and problem-solving? Nine American trainers, one Tanzanian trainer, and one Tanzanian student participated in my study. Each participant filled out a questionnaire geared toward understanding their training methods and perceptions of participant's skills and abilities. After …

Adult Attachment Styles And Psychopathic Traits: A Relationship Mediated By Empathy And Emotional Regulation?, Chelsea Heim

USC Aiken Psychology Theses

Psychopathic personality traits encompass an array of characteristics that emerge early in life and are influenced by insecure attachments between children and their parents. Disruptions in parent-child interactions also affect the development of empathy (Panfile & Laible, 2010) and emotion regulation (Waters, S. F., Virmani, E. A., Thompson, R. A., Meyer, S., Raikes, H. A. & Jochem, R., 2010), which contributes to lasting impairments in interpersonal working models about the self and others (Mack, Hackney & Pile, 2010). The interactions between psychopathy and insecure attachment, low levels of empathy, and the ability to regulate one’s emotions have been separately investigated …
