Hypomania And The Effects Of Working Memory Load On Risk-Taking, Joseph B. Todd
College of Graduate Studies: Theses & Dissertations
Hypomania is an episodic mood state that closely resembles mania, and it is characterized by irritability, euphoria, racing thoughts, and impulsivity. The present study focuses on risk-taking, a behavioral manifestation of impulsivity, and the potential working memory mechanisms responsible for eliciting this behavior in people affected by hypomanic symptoms. Specifically, research suggests that taxing working memory accelerates the process by which individuals with high levels of hypomanic symptoms engage in risk-taking. The purpose of the current study was to examine the effects on hypomanic traits and working memory taxation on a behavioral measure of risk-taking. One hundred and forty-five participants …

Tornado Trouble: How Can Current Tornado Warnings Be Improved?, Jonathan P. Evans
College of Graduate Studies: Theses & Dissertations
There are many unnecessary deaths from tornadoes every year (NOAA.org, 2013). Although there have been great advancements in tornado warning systems (Coleman, Knupp, Spann, Elliot, & Peters, 2010), more changes to systems could be made to motivate people to take action in preparation for tornadoes (Brotzge & Donner, 2013). Protection motivation theory outlines the process by which we assess threats and decide whether or not preventative actions are worth performing. If the threat is perceived as severe enough and the preventative actions are seen as capable of mitigating the threat, the individual is motivated to act (Rogers, 2000). One means …
Neural Correlates Of Episodic Memory Formation In Children And Adults,

Neural Correlates Of Episodic Memory Formation In Children And Adults, Lingfei Tang
Wayne State University Theses
The medial temporal lobe (MTL) and prefrontal cortex (PFC) are two key brain regions that support episodic memory formation in both children and adults, but the functional developmental of these regions remains unclear. In this study, we investigated the development of neural correlates of episodic memory formation using functional MRI with a subsequent memory paradigm, administered to a cross-sectional sample of 83 children and adults. We found that MTL subregions showed an age-related increase in activation supporting memory formation of complex scenes. In addition, a functionally defined scene-sensitive region in the posterior MTL also showed similar increase and predicted better …
The Effects Of Tablets On Learning: Does Studying From A Tablet Computer Affect Student Learning Differently Across Educational Levels,

The Effects Of Tablets On Learning: Does Studying From A Tablet Computer Affect Student Learning Differently Across Educational Levels, Devin M. Nishizaki
CMC Senior Theses
In recent years, students and educators alike have utilized new technologies such as tablet computers as a means of enhancing the learning process. While prior research suggests that these implementations within the classroom provide a new and beneficial method of relaying and learning information, scientists have begun to explore the possible side effects that these technologies have on the learning process. Although much of the current literature suggests that learning from an electronic screen does not affect efficacy compared to learning from printed text (Bayliss et al., 2012; Dundar & Akcayir, 2012), researchers continue to explore the possible consequences that …
Reducing Subjectivity: Meditation And Implicit Bias,

Claremont McKenna College
Reducing Subjectivity: Meditation And Implicit Bias, Diana M. Ciuca
CMC Senior Theses
Implicit association of racial stereotypes is brought about by social conditioning (Greenwald & Krieger, 2006). This conditioning can be explained by attractor networks (Sharp, 2011). Reducing implicit bias through meditation can show the effectiveness of reducing the rigidity of attractor networks, thereby reducing subjectivity. Mindfulness meditation has shown to reduce bias from the use of one single guided session conducted before performing an Implicit Association Test (Lueke & Gibson, 2015). Attachment to socially conditioned racial bias should become less prevalent through practicing meditation over time. An experimental model is proposed to test this claim along with a reconceptualization of consciousness …
Differences In Auditory Imagery Self-Report Predict Neural And Behavioral Outcomes,

Bucknell University
Differences In Auditory Imagery Self-Report Predict Neural And Behavioral Outcomes, Andrea R. Halpern
Faculty Journal Articles
Mental imagery abilities vary among individuals, as shown both by objective measures and by self-report. Few imagery studies consider auditory imagery, however. The Bucknell Auditory Imagery Scale is a short self-report measure encompassing both Vividness and Control subscales for musical, verbal, and environmental sounds. It has high internal reliability, no relation to social desirability, and only a modest relation to musical training. High scores on Vividness predict fewer source memory errors in distinguishing heard from imagined tunes on a recognition test, and better performance on pitch imitation tasks. Furthermore, higher scores are related to hemodynamic response and gray matter volume …

The Effects Of Social Anxiety And State Anxiety On Visual Attention: Testing The Vigilance–Avoidance Hypothesis, J. Suzanne Singh, Michelle C. Capozzoli, Michael Dodd, Debra Hope
Department of Psychology: Faculty Publications
A growing theoretical and research literature suggests that trait and state social anxiety can predict attentional patterns in the presence of emotional stimuli. The current study adds to this literature by examining the effects of state anxiety on visual attention and testing the vigilance– avoidance hypothesis, using a method of continuous visual attentional assessment. Participants were 91 undergraduate college students with high or low trait fear of negative evaluation (FNE), a core aspect of social anxiety, who were randomly assigned to either a high or low state anxiety condition. Participants engaged in a free view task in which pairs of …

Neuropsychological, Cognitive And Physiological Implications Of Barefoot Running On Working Memory, Shelley Ann Floyd
UNF Graduate Theses and Dissertations
The aim of the present study was to compare the effects of barefoot versus shod running on working memory. I recruited exercise science students from the University of North Florida who exercised recreationally. Participants ran both barefoot and shod while hitting targets (poker chips) on a running track and without targets. I measured working memory using backward digit recall and also recorded participants’ heart rate, speed, and target accuracy. The main finding from this study was that working memory performance increased in the barefoot condition when participants hit targets (poker chips). This result supports the idea that additional attention is …

Developing Executive Functions Through Mindfulness Training In School-Aged Children, Ashley Black Adams
PCOM Psychology Dissertations
Well-developed executive functions are necessary for successful classroom functioning. Students with executive function deficits can fall behind academically as well as socially and emotionally, relative to their same-aged peers. Effective interventions for developing executive functions within the school environment are essential for addressing this issue. This study examines changes in students’ executive functions as a result of their participation in a mindfulness training intervention. Participants included four ten-year old elementary school boys who took part in a ten-week mindfulness training intervention. The data were generated through pre and post assessments with an executive function teacher rating scale and a Goal-Attainment …

The Development And Tryout Of A Program Designed To Increase Students' Multiplication Fact Fluency, Linton D. Williams
PCOM Psychology Dissertations
Fluency skills are fundamental to the ability to complete relatively more complex problems using less mental energy. Most math curriculums do not stress the importance of automaticity of math facts. Variations in teaching styles and teaching modality seem to negate the true purpose for cementing and rapidly retrieving math facts. This study put to the test a program that was designed to increase students’ ability to retrieve multiplication facts fluently. The program exercised cognitive structures and enabled students to retrieve multiplication facts quickly. The results of a matched-pairs t-test indicated that after the students completed the course of the program, …

University of Kentucky
Emotional Enhancement And Repetition Effects During Working Memory In Persons With Mild Cognitive Impairment, Lucas S. Broster
Theses and Dissertations--Clinical and Translational Science
This dissertation introduces a framework for understanding differences in how emotional enhancement effects might influence memory in aging adults and then summarizes the findings of three studies of how repetition effects and emotional enhancement effects influence working memory in older adults without cognitive impairment (NC), older adults with amnestic mild cognitive impairment (MCI), and older adults with mild Alzheimer’s disease (AD). In these experiments, individuals with AD showed cognitive impairment in terms of accuracy and reaction time, but individuals with MCI showed milder behavioral impairment that was confined to manipulations of working memory. Individuals with AD showed relative sparing of …

Binghamton University
Mind-Craft: Exploring The Relation Between "Digital" Visual Experience And Orientation In Visual Contour Perception, Daniel Hipp
Graduate Dissertations and Theses
Visual perception depends fundamentally on statistical regularities in the environment to make sense of the world. One such regularity is the orientation anisotropy typical of natural scenes; most natural scenes contain slightly more horizontal and vertical information than oblique information. This property is likely a primary cause of the “oblique effect” in visual perception, in which subjects experience greater perceptual fluently with horizontally and vertically oriented content than oblique. However, recent changes in the visual environment, including the “carpentered” content in urban scenes and the framed, caricatured content in digital screen media presentations, may have altered the level of orientation …

Imagining Accomplishments From Differing Visual And Temporal Perspectives, Deanna C. Hall
Theses and Dissertations (Comprehensive)
The current research examined the relationship between grammatical aspect (GA) (imperfective vs. past perfect) and accomplishment verbs in event representation in Experiment 1, and then investigated the influence of visual perspective taking on this representation process in Experiment 2. Electroencephalography (EEG) was recorded with slow cortical potentials (SCPs) acting as a measure of cognitive processing during the imagination period, and behavioural measure questionnaires provided ratings of vividness, temporal component, and importance of the imagined events.
It was hypothesized for Experiment 1 that imagining imperfective events would result in more negative SCP amplitudes than when imagining events with past perfect aspect, …

Activating The Biological And Behavioral Immune Systems, Julia Christensen
Departmental Honors Projects
Psychology recognizes two distinct facets of the immune system: the biological immune system (BIO), covering all processes of the typical immune system, and the behavioral immune system (BEH), a set of cognitive, emotional, and behavioral responses to environmental stimuli. Research on this dual immune system indicates that each is capable of influencing the other (Schaller & Park, 2011). For example, perception of illness in others can activate the sympathetic nervous system (Schaller, Miller, Gervais, Yager, & Chen, 2010). Furthermore, evidence suggests that these two systems are capable of influencing moral judgment (Inbar, Pizarro, & Bloom, 2008). This study aims to …
The Effect Of Emotion On Associative And Item Memory,

The Effect Of Emotion On Associative And Item Memory, Priyanga Jeyarathnarajah
Theses and Dissertations (Comprehensive)
Numerous studies to date have demonstrated superior memory for emotional compared to neutral stimuli (Kensinger & Corkin, 2004; Bennion et al., 2013). This finding, although relatively stable across the item memory literature, becomes less consistent when examined in tasks measuring memory for associative or source information (Chiu et al., 2013). For this reason, the present study set out to examine how emotional content (negative, positive and neutral word pairs) influences memory in two distinct associative and item recognition tasks: associative identification (AI), associative reinstatement (AR), paired-item recognition, and single-item recognition. In measuring the influence of emotion on associations using an …

Electrophysiological And Behavioral Working Memory Differences Between Musicians And Non-Musicians, Benjamin P. Richardson
All Master's Theses
The current study examines the P300 brainwave and working memory differences between musicians and non-musicians. Differences in aspects of recorded electrical brain activity have been used to quantify differences in updating processes of working memory possibly related to differences in amount of music experience. The current study is designed to partially replicate and enhance a method previously implemented in research describing how music experience may be associated with differences in visual processing as well auditory working memory and executive function. Behavioral data were collected using six standardized subtest measures of the TOMAL – II, followed by ERP recordings during a …

The Effects Of Feedback Sequence On Cognitive Performance, Travis W. Pyle
All Master's Theses
The current study tested the effects of feedback sequence on performance on a visual-spatial task. Twenty-three female participants were randomly assigned to one of five feedback sequence conditions which occurred after two consecutive trials of a hole-punch task. The five feedback sequence conditions consisted of positive-positive (i.e., positive feedback followed by positive feedback), positive-negative, negative-positive, negative-negative, and a no-feedback control group. Positive feedback was presented as a 80%-90% accuracy range whereas negative feedback was a 30%-40% accuracy range. Third trial accuracy and completion time were measured as was locus of control via the Internal Control Index (ICI) survey. Analyses revealed …
A Naturalistic Computational Model Of Human Behavior In Navigation And Search Tasks,

A Naturalistic Computational Model Of Human Behavior In Navigation And Search Tasks, Brandon S. Perelman
Dissertations, Master's Theses and Master's Reports - Open
Planning, navigation, and search are fundamental human cognitive abilities central to spatial problem solving in search and rescue, law enforcement, and military operations. Despite a wealth of literature concerning naturalistic spatial problem solving in animals, literature on naturalistic spatial problem solving in humans is comparatively lacking and generally conducted by separate camps among which there is little crosstalk. Addressing this deficiency will allow us to predict spatial decision making in operational environments, and understand the factors leading to those decisions. The present dissertation is comprised of two related efforts, (1) a set of empirical research studies intended to identify characteristics …

The Relationship Between English Language Learners And Reading Disabilities Profiles: Language Acquisition Vs. Reading Disabilities, Emily S. Hartz
PCOM Psychology Dissertations
School psychologists are asked to determine whether or not a student’s limited English proficiency affects his or her eligibly for special education services. Scores from language proficiency tests, such as the WIDA ACCESS for ELLs English Language Proficiency Test, are often the only data available that speak to a student’s language proficiency. There is little research that speaks to how scores on these tests relate to performance on diagnostic testing for special education, specifically achievement testing. In this sample of data drawn from a population of English language learners, who also qualify for special education services under the disability of …

The Educational Potential Of Alcohol-Related Flushing Among Chinese Young People, Ian M. Newman, Duane F. Shell, Zhaoqing Huang, Ling Qian
Department of Educational Psychology: Faculty Publications
Aim: This paper describes Chinese university students’ understanding of the meaning of the alcohol-related flushing response and how they reacted to their own and someone else’s flushing in a group drinking situation. Method: The researcher surveyed 530 Chinese university students about their understanding of flushing and their perception of how people respond to a person who visibly flushes while drinking alcohol. Findings: Most students did not know about the physiological cause of flushing. There were significant gender differences in both reactions to and perception of responses to a person who flushes. There was no direct relationship between flushing and drinking …
