Caffeine Withdrawal And Dependence: A Review, Alexander Roberts

Williams Honors College, Honors Research Projects

With the prevalence of caffeine use increasing in modern lifestyles, it is important to look at the symptoms of caffeine use, including withdrawal and dependence, and whether these symptoms have implications for addiction. A limited number of assessments have been developed to assess caffeine withdrawal. In order to make a call for more assessments and programs to be developed to assist with healthy caffeine use, this literature review observed recent studies focusing on withdrawal and dependence. Ozsunger et al. (2009) classified caffeine withdrawal into three categories of symptoms. Three years later, Juliano et al. (2012) used an experimental approach to …

Examining Attentional Control And Processing Speed Deficits As Underlying Mechanisms Of Neuropsychological Impairment In Schizophrenia, Mayte Forte

Graduate Masters Theses

Neuropsychological impairment is a key characteristic of schizophrenia (SZ), but its cognitive profile and underlying information processing mechanisms are not yet well understood. We compare patterns of neuropsychological functioning in 85 persons with SZ and 76 healthy controls across measures of intelligence, memory, and executive function. We then test the hypothesis that neuropsychological impairment in SZ is related to dual deficits in two related but distinct information processes: processing speed and attentional control. All research participants completed Wechsler Adult Intelligence Scale-Third Edition (WAIS-III), Wechsler Memory Scale Third Edition (WMS-III), and Wisconsin Card Sorting Test (WCST), all of which provided measures …

The Domain-Generality And Durability Of Efficient Learning, Christopher Zerr

Arts & Sciences Electronic Theses and Dissertations

People differ in how quickly they learn information and how long they remember it, and a common finding in the literature is that a quicker rate of learning coincides with better retention for the learned material. Zerr and colleagues (2017) termed the relation between learning rate and retention as learning efficiency, with more efficient learning representing both a faster acquisition rate and better memory performance after a delay. Zerr et al. also demonstrated in separate experiments that how efficiently someone learns is stable across a range of days and years. The current thesis includes two experiments addressing additional questions …

Exploring The Underlying Mechanisms Of Structure Building, Reshma Gouravajhala

Arts & Sciences Electronic Theses and Dissertations

Structure building, the ability to build a coherent mental model of any narrative, requires the identification and integration of important parts of that narrative, as well as the suppression of irrelevant details. Critically, while individual differences in structure building have been shown to have important consequences in the classroom, little has been concluded about underlying deficits and causal mechanisms of low structure building ability. In the present study, we tested the theory that an impaired ability to suppress unimportant details is low structure builders’ sole deficit (Gernsbacher, 1990). We presented participants with educationally authentic text materials that offered varying degrees …

Combining An Intuitive Art Workshop And Neuroscience Rituals To Make Us Happy, Audrey Gran Weinberg

The STEAM Journal

One might wonder how intuitive art can connect to neuroscience and how this could be accomplished. In this descriptive article, research connecting art therapy and neuroscience has been collected and a workshop on Intuitive Painting has been described in detail. The connection was made by the author based on an article by Barker (2017), ‘4 Rituals to be more Happy,’ who writes a popular science blog. The rituals: gratefulness, expressing negative emotions, decision making and human touch were combined with Dr. Pinkie Feinstein’s method of Intuitive Painting in a small group setting. Although subjective, it would seem that at least …

Personal Values Of Principals And Their Manifestation In Student Behaviour : A District-Level Study In Pakistan, Christopher Branson, Sharifullah Baig, Abida Begum

Sharifullah Baig

Although there is growing research evidence to support the view that the leadership practice of the school principal is the second-most important influence on student learning behind classroom teaching, there is no clarity about what, exactly, the principal is meant to do to ensure this outcome. Hence, Leithwood et al. (2010) propose that one of the principal’s important influences on student learning is the ‘rational’ path, which includes the issue of school-wide disciplinary climate. This argues that the principal plays a pivotal role in establishing the school-wide disciplinary climate that aids student learning. This article reports upon research conducted in …

Prospective Associations Of Homocysteine, Executive Function, And Depressive Symptoms, Peter J. Dearborn

Electronic Theses and Dissertations

Associations of cardiovascular risk factors, cognitive performance, and depressive symptoms have been well established. However, the directionality of these associations as well as the specificity of these associations with respect to executive function are less clear. Additionally few studies have determined whether genetic risk factors, such as apolipoprotein-E4 (APOE-E4) genotype, and age moderate the associations of cardiovascular risk factors such as homocysteine with changes in depressive symptoms and how these associations may be mediated by cognitive performance. The primary aim of this study was to analyze the bidirectional associations of a full range of cognitive domains and symptoms of depression …

Increasing Student Registered Nurse Anesthetists Clinical Self-Efficacy Using Peer Mentoring, Megan Christine Bass

Doctoral Projects

The purpose of this project is to determine if clinical self-efficacy is increased in SRNAs at The University of Southern Mississippi after participation in the peer mentoring program. The project was a one-group pre and posttest design in a sample of SRNAs who received peer mentoring. To evaluate the students’ perceived clinical self-efficacy before and after the peer mentoring educational intervention, the Rowbotham and Schmitz Student Self-Efficacy scale (SSE) (2013) was adapted and administered to second-year SRNAs (N=17). Clinical performance, skill and knowledge development, social interaction with clinical faculty, and coping with clinical stress are the four areas evaluated by …

Effects Of Restrained Eating On Episodic Memory And Implications For Homeostatic Appetite Regulation, Morgan Kindel

Student Scholar Symposium Abstracts and Posters

Recent studies in the fields of Psychology and Neuroscience suggest a relationship between episodic memory and appetite regulation. A majority of these studies have used BMI as an important variable in this relationship and have found mild episodic memory deficits to be more likely in individuals with higher BMI’s. The goal of this research was to determine whether restrained disordered eating, regardless of BMI, influenced episodic memory and appetite regulation. Initially, we predicted that individuals showing dietary restraint would show signs of a stronger episodic memory, and therefore would have weaker hunger cues and stronger satiety cues, and that in …

Parent-Teacher Communication About Children With Autism Spectrum Disorder: An Examination Of Collaborative Problem Solving, Gazi F. Azad, Mina Kim, Steven C. Marcus, David S. Mandell, Susan M. Sheridan Dr.

Department of Educational Psychology: Faculty Publications

Effective parent-teacher communication involves problem-solving concerns about students. Few studies have examined problem solving interactions between parents and teachers of children with autism spectrum disorder (ASD), with a particular focus on identifying communication barriers and strategies for improving them. This study examined the problem-solving behaviors of parents and teachers of children with ASD. Participants included 18 teachers and 39 parents of children with ASD. Parent-teacher dyads were prompted to discuss and provide a solution for a problem that a student experienced at home and at school. Parents and teachers also reported on their problem-solving behaviors. Results showed that parents and …

Regulating Rumination By Anger: Evidence For The Mutual Promotion And Counteraction (Mpmc) Theory Of Emotionality, Jun Zhan, Fan Tang, Mei He, Jin Fan, Jing Xiao, Chang Liu, Jing Luo

Publications and Research

Unlike the strategy of cognitive regulation that relies heavily on the top-down control function of the prefrontal cortex (PFC), which was recently found may be critically impaired in stressful situations, traditional Chinese philosophy and medicine views different types of emotionality as having mutual promotion and counteraction (MPMC) relationships, implying a novel approach that requires less cognition to emotional regulation. Actually, our previous studies have indicated that anger responses could be successfully regulated via the induction of sadness, and this efficiency could not be influenced by stress, thus providing evidences for the hypothesis of “sadness counteracts anger” (SCA) proposed by the …

Assessing The Relationships Between Multicultural Training, Cultural Identity, And Multicultural Counseling Competence Among Master’S Level Counseling Students, Rachel Reinders

Theses and Dissertations

The discrepancy between the demographics of the American population and mental health providers means that providers will increasingly be called upon to work with clients who are different from the provider. This study evaluated the relationship between multicultural competence (MCC), ethnic identity, and worldview variables for Master’s level counseling students enrolled in an introductory multicultural counseling course. It also included an analysis of course factors. A total of 201 students completed the survey at both the beginning and end of the semester. Students reported higher levels of ethnic identity development at the end of the semester as compared to the …

Print Exposure Modulates The Effects Of Repetition Priming During Sentence Reading, Matthew W. Lowder, Peter C. Gordon

Psychology Faculty Publications

Individual readers vary greatly in the quality of their lexical representations and consequently in how quickly and efficiently they can access orthographic and lexical knowledge. This variability may be explained, at least in part, by individual differences in exposure to printed language, as practice at reading promotes the development of stronger reading skills. The current eye-tracking experiment tests the hypothesis that the efficiency of word recognition during reading improves with increases in print exposure by determining whether the magnitude of the repetition priming effect is modulated by individual differences in scores on the Author Recognition Test (ART). Lexical repetition of …

How Does Increasing The Power Of Retrieval Cues Change The Experience Of Remembering?, Oyku Uner

Arts & Sciences Electronic Theses and Dissertations

Increasing the power of retrieval cues typically enhances recall and recognition. Is this driven by remembering, knowing, or both? The current study used the remember/know paradigm in different recall tasks that manipulated the power of retrieval cues. In the first two experiments, participants studied words in a semantic or phonetic context, and were tested in one of these contexts, resulting in two match and two mismatch conditions. Participants recalled more in the match conditions, and this was driven by remembering. In the third experiment, participants studied multiple word lists and were tested immediately after each list with varying number of …

The Effects Of Repeated Lineups And Delay On Eyewitness Identification, Wenbo Lin

Arts & Sciences Electronic Theses and Dissertations

Prior eyewitness research has examined the effects of repeated identification procedures and delays on eyewitness identification, but these studies have either confounded these two factors or studied them in isolation. Experiment 1 attempted to disentangle these factors through systematic manipulations of the number of repeated lineups and the length of delay between the original event and the first lineup. Experiment 2 examined whether the length of delay between two lineups (Lineups 1 and 2) affects the subsequent lineup identification decisions. We found that people were more inclined to choose when a lineup was repeated. A longer delay between the crime …

The Impact Of Delay On Retrieval Success In The Parietal Memory Network, Nathan Anderson

Arts & Sciences Electronic Theses and Dissertations

Recent work has identified a Parietal Memory Network (PMN), which exhibits regular patterns of activation during memory encoding and retrieval. Among these characteristic patterns, this network displays a strong “retrieval success” effect, showing greater activation for correctlyremembered studied items (hits) compared to correctly-rejected novel items (CRs). To date, most relevant studies have used short retention intervals. Here, we ask if the retrieval success effect seen in the PMN would remain consistent over a delay. Twenty participants underwent fMRI while encoding and recognizing scenes. Greater activity for hits than for correctly-rejected lures within PMN regions was observed after a short delay …

Quizzing And Restudy Dynamics In A Tst Paradigm: The (Null) Effect Of Feedback And The (Significant) Effects Of Metacognition, Francis Anderson

Arts & Sciences Electronic Theses and Dissertations

In authentic educational settings, using formative quizzes or tests can improve students’ memory by direct strengthening of the memory trace. There are other indirect effects of testing, however, such as improved understanding of what one does and does not know. That is, quizzes can benefit students’ metacognitive awareness, which may in turn affect their restudy behaviors. We tested whether different types of feedback (correct/incorrect, correct answer, or minimal) differentially affected students’ metacognition, changed their restudy behaviors, and influenced final test performance. We found no effect of feedback type, but were able to better understand quizzing and restudy dynamics in an …

Cognitive Behavioral Therapy Is Associated With Enhanced Cognitive Control Network Activity In Major Depression And Posttraumatic Stress Disorder, Zhen Yang, Desmond Oathes, Kristin Linn, Steven Bruce, Theodore Satterthwaite, Philip Cook, Emma Satchell, Haochang Shou, Yvette Sheline

Psychology Faculty Works

BACKGROUND: Both major depressive disorder (MDD) and posttraumatic stress disorder (PTSD) are characterized by depressive symptoms, abnormalities in brain regions important for cognitive control, and response to cognitive behavioral therapy (CBT). However, whether a common neural mechanism underlies CBT response across diagnoses is unknown. METHODS: Brain activity during a cognitive control task was measured using functional magnetic resonance imaging in 104 participants: 28 patients with MDD, 53 patients with PTSD, and 23 healthy control subjects; depression and anxiety symptoms were determined on the same day. A patient subset (n = 31) entered manualized CBT and, along with controls (n = …

An Assessment Of Frontal Lobe Activity And Bdnf Levels Following Concussion In Collegiate Athletes: A Near-Infrared Spectroscopy Study, Keara Kangas

All NMU Master's Theses

Impacts to the head that are associated with sports related injuries, can result in a mild traumatic brain injury (mTBI), known as a concussion. Previous research has assessed how mTBIs affect the brain, but these assessments are limited in their ability to directly measure the consequences of mTBI. Along with concussion assessments, only a few studies have used neuroimaging techniques to evaluate brain injury. This study utilized a neuroimaging technique that is inexpensive, non-invasive, and portable, to measure brain activity post-concussion. In particular, near-infrared spectroscopy (NIRS) was used to measure prefrontal cortex (PFC) activity during the dot-probe task of affective …

Life-Long Creativity: Changing The Narrative Of Aging And Retirement, Jennifer K. Gippel Dr

Creativity and Change Leadership Graduate Student Master's Projects

The current narratives and stereotypes around retirement and aging are both inaccurate and incomplete. The popular media regularly portrays retirees and older citizens as blissfully happy but bland; or physically feeble and forgetful. Rarely are they portrayed as achievers and vibrant problem solvers. Instead they are perceived by policy makers as a problem to be solved. This project offers a different narrative ― one that presents retirement and aging as a unique time of creative opportunity, possibility, and freedom to choose. The primary outcome of the project is two chapters of a book entitled: Retirement by design: How to discover …

Do Learners Have Insight Into The Levels Of Processing Effect? Exploring Unresolved Levels Of Processing Phenomena With Judgments Of Learning, Elif Eylul Tekin

Arts & Sciences Electronic Theses and Dissertations

The levels of processing (LOP) effect shows that semantic processing leads to better retention than other types of processing. The effect is routinely obtained on many types of tests, yet, to this day, its mechanisms are still debated and it is poorly understood. In two old/new recognition experiments, I investigated potential explanations as to why the LOP effect occurs under intentional learning instructions. I asked a) whether subjects were aware of the LOP effect while they were studying the material, b) whether explicitly encouraging subjects to study the words with their idiosyncratic strategies would eliminate the effect, and c) whether …

Elements Of Moral Functioning In Sport And School, Christopher Funk

Dissertations

Moral functioning is complex and implicates numerous cognitive and affective processes. Drawing upon Rest’s four-component model of moral functioning and more recent dual-process accounts of cognition, the current study examined a model of moral functioning in both sport and school contexts. Specifically, drawing upon the empirical record, a model of moral functioning was proposed and tested wherein moral identity influenced the adoption of specific contesting orientations, which, in turn, influenced prosocial and antisocial behaviors, both directly and indirectly via moral foundations and moral disengagement. Fit of the model was moderately strong in both contexts, though significant contextual differences emerged, both …

Contributions Of Appetitive And Aversive Motivational Systems To Decision-Making, Heather E. Soder

USF Tampa Graduate Theses and Dissertations

Optimal decision-making entails outcome evaluation, comparing received costs and benefits with predicted costs and benefits. The anterior cingulate cortex (ACC), a brain area with major connections to the appetitive and aversive motivation systems, may provide the neural substrate of this evaluation process. One way to measure the relative contribution of these systems on decision-making is to measure individual differences in risk-taking behaviors. For individuals who make risky choices, this evaluation step may be biased: some show a preference for immediate, short-term rewards (increased appetitive system), while devaluing the long-term consequences of their choices (decreased aversive system). However, most studies supporting …

Preliminary Evidence For The Impact Of Combat Experiences On Gray Matter Volume Of The Posterior Insula, Ashley N. Clausen, Sandra A. Billinger, Jason-Flor V. Sisante, Hideo Suzuki, Robin L. Aupperle

Department of Educational Psychology: Faculty Publications

Background: Combat-exposed veteran populations are at an increased risk for developing cardiovascular disease. The anterior cingulate cortex (ACC) and insula have been implicated in both autonomic arousal to emotional stressors and homeostatic processes, which may contribute to cardiovascular dysfunction in combat veteran populations. The aim of the present study was to explore the intersecting relationships of combat experiences, rostral ACC and posterior insula volume, and cardiovascular health in a sample of combat veterans.

Method: Twenty-four male combat veterans completed clinical assessment of combat experiences and posttraumatic stress symptoms. Subjects completed a magnetic resonance imaging scan and autosegmentation using FreeSurfer was …

It's More Than Self-Presentation: Mum Effects Can Reflect Private Discomfort And Concern For The Recipient, Jayson L. Dibble

Faculty Publications

Is the reluctance to share bad news (i.e., the MUM effect) motivated more by a public display or private concern, and does it benefit mainly the messenger or the recipient? An experiment (N = 309) that crossed good/bad news with three communication channels (face to face, text messaging, email) revealed that messenger reluctance was greatest under conditions of bad news and did not vary based on channel through which the recipient contacted the messenger. In contrast with earlier work, this MUM effect was more consistent with a private fear of distressing the recipient. Theoretical implications and limitations are discussed.

The Effect Of Text Color And Text Grouping On Attention And Short Term Recall Memory, Emily Haynes

Honors College Research

This study sought to discover whether there was a connection between the attentional draw of a word, as represented by text color and grouping, and the likelihood of it being transferred into short term recall memory. College students at Harding University in Searcy, Arkansas were given one of six timed memory test scenarios and asked to recreate the list to the best of their ability. The students were then asked to complete a series of post-test questions designed to measure their perception of their own performance on the test. The students were also asked to complete a demographics questionnaire that …

Enrichment Of Putatively Damaging Rare Variants In The Dyx2 Locus And The Reading-Related Genes Ccdc136 And Flnc, Andrew K. Adams, Shelley D. Smith, Dongnhu T. Truong, Erik G. Willcutt, Richard K. Olson, John C. Defries, Bruce F. Pennington, Jeffrey R. Gruen

Psychology: Faculty Scholarship

Eleven loci with prior evidence for association with reading and language phenotypes were sequenced in 96 unrelated subjects with significant impairment in reading performance drawn from the Colorado Learning Disability Research Center collection. Out of 148 total individual missense variants identified, the chromosome 7 genes CCDC136 and FLNC contained 19. In addition, a region corresponding to the well-known DYX2 locus for RD contained 74 missense variants. Both allele sets were filtered for a minor allele frequency ≤0.01 and high Polyphen-2 scores. To determine if observations of these alleles are occurring more frequently in our cases than expected by chance in …

Search Guidance Can Be Adjusted By Experience With Search Discriminability, Junha Chang

Masters Theses

Several recent studies show that previous experience can influence observers’ search strategy in a way that improves search performance. The purpose of the present study is to investigate how the experience of difficult color discriminability affects search strategies. Two participant groups either experienced difficult color discriminability in a half of the trials (i.e., hard-discrimination group) or experienced easy search in all trials (i.e., easy-discrimination group) in a dual-target search task. Participants were required to respond to the presence of a target (colored T) among distractors (colored pseudo-L). Eye movements were recorded to understand which feature information is used to guide …

A Simulated Walk In Nature: Testing Predictions From The Attention Restoration Theory, Corey Crossan

Electronic Thesis and Dissertation Repository

Attention Restoration Theory (ART) predicts that top-down processing during everyday activities can cause attentional fatigue and that bottom-up processing that occurs when people experience nature will be restorative (Kaplan, 1995). The present study examined this prediction by exposing participants to three different conditions using a repeated measures design: a control condition during which participants walked on a typical treadmill, a nature/restorative condition during which participants walked on the same treadmill, experiencing a simulated nature walk, and a perturbation condition that included the same simulated nature scene but also required top-down processing during the walk. The findings supported ART predictions. As …
