The Neuropsychological Functioning Of Older Adults Pre- And Post-Cognitive Training With A Brain Plasticity-Based Computerized Training Program, Shannon M. Sorenson

Graduate Masters Theses

The present study evaluates the effectiveness of Posit Science Cortex™ with Insight Drive Sharp™ as a tool for improving neuropsychological functioning in a normal aging sample. The purpose of the DriveSharp™ training program is to help an individual improve his or her visual attention and useful field of view. Each exercise continually adapts to the individual’s performance so that the training is always at an appropriate level for that specific person. Thirty-two healthy older adult participants were randomly assigned to either the active intervention group (DriveSharp™) or a waitlist control group. Participants in the intervention group were required to engage …

Rapid Knowledge Assessment (Rka): Assessing Students Content Knowledge Through Rapid, In Class Assessment Of Expertise, Erin Margaret O'Connell

Theses and Dissertations

Understanding how students go about problem solving in chemistry lends many possible advantages for interventions in teaching strategies for the college classroom. The work presented here is the development of an in-classroom, real-time, formative instrument to assess student expertise in chemistry with the purpose of developing classroom interventions. The development of appropriate interventions requires the understanding of how students go about starting to solve tasks presented to them, what their mental effort (load on working memory) is, and whether or not their performance was accurate. To measure this, the Rapid Knowledge Assessment (RKA) instrument uses clickers (handheld electronic instruments for …

Age Differences In Reward Anticipation And Memory, Kristen L. Cushman

Masters Theses & Specialist Projects

Aging research on item- and associative-recognition memory has demonstrated that older adults are deficient in forming associations between two unrelated stimuli. Although older adult performance on tests of item-recognition is similar to younger adult performance, older adults perform worse than younger adults on tests of associative memory (Naveh-Benjamin, Hussain, Guez, & Bar-On, 2003). In addition to the idea that younger adult performance on associative-recognition tests is superior to that of older adults, research has shown that reward cues can enhance motivated learning and item memory performance of younger adults. In an fMRI study that examined the influence of reward anticipation …

The Relationship Between Eating Disorder Symptomology, Critical Body Comments, And Memory Recall, Morgan Littrell

Masters Theses & Specialist Projects

Previous research done in the area of eating disorders suggests many different variables, such as cognitive, biological, and social, that are thought to influence eating disorder development and maintenance. The present study attempts to combine cognitive and sociocultural research findings, memory recall and critical body comments, in an effort to see how, if at all, these two variables affect eating disorder symptomology. Participants for this study were 120 female students that were recruited via Study Board. Participants completed the demographics form, the Eating Disorder Inventory-3 RF, and the Social Hassles Questionnaire. The participants then watched an E-prime presentation of different …

Capacity Coefficient Variations, Joseph W. Houpt, Andrew Heathcote, Ami Eidels, Nathan Medeiros-Ward, Jason Watson, David Strayer

Joseph W. Houpt

The capacity coefficient has become an increasingly popular measure of efficiency under changes in workload. It has been used in applications ranging from psychophysical detection tasks to complex cognitive tasks, as well as in addressing questions in social and clinical psychology. The basic formulation compares response times to each stimulus property (or task) in isolation to response times with all stimulus properties (or tasks) at the same time. A number of variations on the basic capacity coefficient have been used, both in the experimental design and in the calculations, and many more are possible. Here we outline the theoretical reasons …

Teleological Reasoning In Adults: Believing In The Purpose Of Events, Carrie Jeanette Guggenmos

Masters Theses & Specialist Projects

Teleological reasoning reflects the general tendency to view objects, behaviors and events in terms of their “purpose.” Although healthy educated adults tend to refrain from committing errors in teleological reasoning about objects, our knowledge regarding how adults reason about events is limited. It has been suggested that teleological reasoning biases our interpretations of emotionally significant and unexpected life events of which a physical or social cause is absent or unsatisfactory. The current investigation seeks to better understand the types of events that evoke a teleological perspective and the conditions and individual difference factors that facilitate it. The results revealed that …

Mindscapes And Landscapes: Hayek And Simon On Cognitive Extension, Leslie Marsh

Leslie Marsh

Hayek’s and Simon’s social externalism runs on a shared presupposition: mind is constrained in its computational capacity to detect, harvest, and assimilate “data” generated by the infinitely fine-grained and perpetually dynamic characteristic of experience in complex social environments. For Hayek, mind and sociality are co-evolved spontaneous orders, allowing little or no prospect of comprehensive explanation, trapped in a hermeneutically sealed, i.e. inescapably context bound, eco-system. For Simon, it is the simplicity of mind that is the bottleneck, overwhelmed by the ambient complexity of the environmental. Since on Simon’s account complexity is unidirectional, Simon is far more ebullient about the prospects …

Asymmetry In Resting Alpha Activity: Effects Of Handedness, Ruth E. Propper, Jenna Pierce, Mark W. Geisler, Stephen D. Christman, Nathan Bellorado

Department of Psychology Faculty Scholarship and Creative Works

Frontal electroencephalographic (EEG) alpha band power during rest shows increased right, and/or decreased left, hemisphere activity under conditions of state or trait withdrawal-associated effect. Non-right-handers (NRH) are more likely to have mental illnesses and dispositions that involve such withdrawal-related effect. The aim of the study was to examine whether NRH might be characterized by increased right, relative to left, hemisphere activity during rest. Methods: The present research investigated that hypothesis by examining resting EEG alpha power in consistently-right-handed (CRH) and NRH individuals. Results: In support of the hypothesis, NRH demonstrated decreased right hemisphere alpha power, and therefore increased right hemisphere …

A Hybrid Brain-Computer Interface Based On Motor Intention And Visual Working Memory, Ching-Chang Kuo

Doctoral Dissertations

Non-invasive electroencephalography (EEG) based brain-computer interface (BCI) is able to provide alternative means for people with disabilities to communicate with and control over external assistive devices. A hybrid BCI is designed and developed for following two types of system (control and monitor).

Our first goal is to create a signal decoding strategy that allows people with limited motor control to have more command over potential prosthetic devices. Eight healthy subjects were recruited to perform visual cues directed reaching tasks. Eye and motion artifacts were identified and removed to ensure that the subjects' visual fixation to the target locations would have …

Randomized Clinical Trial Of Cognitive Behavioral Therapy (Cbt) Versus Acceptance And Commitment Therapy (Act) For Mixed Anxiety Disorders, Joanna Arch, Georg Eifert, Carolyn Davies, Jennifer C. Plumb Vilardaga, Raphael D. Rose, Michael G. Craske

Psychology Faculty Articles and Research

Objective—Randomized comparisons of acceptance-based treatments with traditional cognitive behavioral therapy (CBT) for anxiety disorders are lacking. To address this research gap, we compared acceptance and commitment therapy (ACT) to CBT for heterogeneous anxiety disorders.

Method—One hundred twenty eight individuals (52% female, mean age = 38, 33% minority) with one or more DSM-IV anxiety disorders began treatment following randomization to 12 sessions of CBT or ACT; both treatments included behavioral exposure. Assessments at pre-treatment, post-treatment, 6-month, and 12-month follow-up measured anxiety specific (principal disorder Clinical Severity Ratings [CSR], Anxiety Sensitivity Index, Penn State Worry Questionnaire, Fear Questionnaire avoidance) and …

The Painful Relationship Shared By Spinal Injury And Sleep Disorders, Pennie Seibert, Christian Zimmerman, Jennifer Valerio, Yustina Rafla, Fred Grimsley

Pennie S. Seibert

Introduction: People who sustain spinal injury (SI) also routinely complain about sleep disturbances. This coexistence negatively impacts general health, well-being, and recovery. Investigations of this complex relationship have been constrained by difficulty in acquiring valid data from people whose sleep disorder (SD) diagnoses are based on complete nocturnal polysomnography (NP) and multiple sleep latency tests (MSLT) rather than simple self-report data.

Methods: We constructed an 111-item questionnaire to use in conjunction with NP, MSLT, the Epworth Sleepiness Scale (ESS), and medical chart reviews of people referred for evaluation of SDs.

Results: We analyzed data from 721people who were diagnosed with …

Characterizing Sleep Disorders In Geriatric Populations, Pennie Seibert, J. Valerio, Y. Rafla, F. Grimsley, C. Zimmerman

Pennie S. Seibert

Sleep disorders (SD) affect approximately one-third of the world population. The presence of SDs occurs at all ages although the presentation and subsequent consequences for an individual’s health change in accordance with the natural aging process. Currently, evaluation of SD is inadequate across all age ranges as it is compromised by under reporting and by relying on self-report rather than professional sleep studies (i.e., nocturnal polysomnography (NP) and multiple sleep latency tests (MSLT)). Moreover, there is a paucity of data specific to older adults. We constructed a 111-item questionnaire to use in conjunction with NP, MSLT, the Epworth Sleepiness Scale …

Beyond Dogma: The Role Of "Evolutionary" Science And The "Embodiment" Of Archetypal Energies, Carroy U. Ferguson

Carroy U "Cuf" Ferguson, Ph.D.

At individual and collective levels (locally, nationally, and globally), humanity is currently entertaining many challenges and opportunities for growth. In my view, these challenges and opportunities are connected to Energy shifts that are taking place on the planet, and the inability of some to move beyond dogma in relating to these Energy shifts. By its pre- and proscriptive nature, dogma fosters limiting beliefs that often interfere with how best to relate to these Energy shifts as vibrational beings in an evolving, vibrational world. Here, I want to briefly identify some of the limiting effects of dogma, and the role of …

Embodied Metaphors And Creative “Acts”, Angela K.-Y. Leung, Suntae Kim, Evan Polman, Lay See Ong, Lin Qiu, Jack A. Goncola, Jeffrey Sanchez-Burks

Ka Yee Angela LEUNG

Creativity is a highly sought after skill. To inspire people’s creativity, prescriptive advice in the form of metaphors abound: We are encouraged to think outside the box, to consider the problem on one hand, then on the other hand, and to put two and two together to achieve creative breakthroughs. These metaphors suggest a connection between concrete bodily experiences and creative cognition. Inspired by recent advances on body-mind linkages under the emerging vernacular of embodied cognition, we explored for the first time whether enacting metaphors for creativity enhances creative problem-solving. In five studies, findings revealed that both physically and psychologically …

Musical Stem Completion: Humming That Note, J.A. Warker, Andrea Halpern

Andrea Halpern

This study looked at how people store and retrieve tonal music explicitly and implicitly using a production task. Participants completed an implicit task (tune stem completion) followed by an explicit task (cued recall). The tasks were identical except for the instructions at test time. They listened to tunes and were then presented with tune stems from previously heard tunes and novel tunes. For the implicit task, they were asked to sing a note they thought would come next musically. For the explicit task, they were asked to sing the note they remembered as coming next. Experiment 1 found that people …

Distinct Visual Coding Strategies Mediate Grasping And Pantomime-Grasping Of 2d And 3d Objects., Scott A. Holmes

Electronic Thesis and Dissertation Repository

An issue of current debate in the visuomotor control literature surrounds whether 2D and 3D objects rely on similar or dissociable visual information in supporting goal-directed grasping. Accordingly, in Experiment One I had participants grasp 2D and 3D objects wherein just-noticeable-difference (JND) scores for aperture shaping were computed to determine the extent to which such actions adhere to the psychophysical principles of Weber’s law. Results demonstrated that JNDs scaled in accordance with Weber’s law in a time-independent and time-dependent manner for 2D and 3D grasping, respectively. In Experiment Two, I sought to further explore the cognitive demands of grasping by …

Phonological Priming In Japanese-English Bilinguals: Evidence From Lexical Decision And Erp, Eriko Ando

Electronic Thesis and Dissertation Repository

One of the main questions in bilingualism is whether the representations activated from one language influence processing of the other language. The current study investigated this issue by examining masked phonological priming effects in Japanese-English bilinguals when English words (e.g., guy) were primed by phonologically related logographic (Kanji) words (e.g., 害, /gai/, “harm”) and also when English words (e.g., guide) were primed by phonologically similar phonogram (Katakana) words (e.g.,サイド, /saido/,”side”). In Experiment 1, lexical decisions to English words were facilitated when they were preceded by phonologically similar versus dissimilar primes, particularly when the primes were one-Kanji words and when they …

The Impact Of Distractor Duration On Spatial Working Memory In Early Childhood, Brian Keiser

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Spatial attention appears to act as a rehearsal mechanism in spatial working memory (Awh, 1999; Awh & Jonides, 2001) as adults have trouble maintaining spatial information in their mind when required to shift their attention to locations unrelated to the to-be-retained location. Futhermore, adults increase intentional directed attention to the to-be remembered location when warned ahead of time that distractors will be present during the memory delay (Awh, 2003). Our initial study looked at the presence of a distractor and its impacts on spatial working memory in children. We found that the distractor did impact three and six year old …

Sports Participation Among South Asian Americans: The Influence Of Acculturation And Value Of Sport, Soumya Palreddy

Theses and Dissertations

Asian Americans, one of the fastest growing communities in recent decades (U.S. Census Bureau, 2008) continue to be underrepresented in sports in the United States. Recent trends in sport participation suggest that while other ethnic/racial minority groups are increasing their presence in sports, Asian Americans may not be increasing at a similar rate (Lapchick, 2008). For example, in collegiate athletics, only .005% of Asian Americans enrolled in college were also engaged in a sport, and in professional sports, only 1-2% of all players in major professional organizations identify as Asian American (Lapchick, 2008). Although statistics continuously reveal this trend, research …

Effects Of Oxygen Deprivation On Pilot Performance And Cognitive Processing Skills: A Pilot Study, David Francis Shideler

Doctoral Dissertations and Master's Theses

According to Federal Aviation Administration (FAA) regulations, pilots flying above 14,000 ft. are required to use supplemental oxygen. The purpose of this study was to examine how oxygen deprivation below 14,000 ft. affects pilot performance using the Frasca Mentor Advanced Aviation Training Device (AATD), and cognitive processing skills using the Automated Neuropsychological Assessment Metrics (ANAM(TM)) cognitive test. The study was conducted in a Normobaric High Altitude Laboratory at simulated altitudes of 5,000 ft. and 14,000 ft. In this pilot study, only five participants were tested; non-significant results of the analysis were anticipated; however, as oxygen levels decreased and time of …

Development And Implementation Of It-Enabled Business Processes: A Knowledge Structure View, Rick Brattin

Graduate Theses and Dissertations

As competitive pressures mount, organizations must continue to evolve their business processes in order to survive. Increasingly, firms are developing new IT-enabled business processes in response to rising competition, greater customer expectations, and challenging economic conditions. The success rate of these projects remains low despite much industry experience and extensive academic study. Managerial and organizational cognition represents a potentially fruitful lens for studying the design and implementation of IT-enabled business processes. This view assumes that individuals are information workers who spend their days absorbing, processing, and disseminating information as they pursue their goals and objectives. Individuals develop cognitive representations, called …

Frequency-Specificity And Pattern-Specificity Of The Buildup Of Auditory Stream Segregation, David Michael Weintraub

UNLV Theses, Dissertations, Professional Papers, and Capstones

During repeating sequences of low (A) and high (B) tones in an "...ABAB..." pattern, the likelihood of hearing two separate streams ("streaming") increases with more repetitions of the patterns, a phenomenon referred to as "buildup". Previous studies have shown that buildup is frequency specific (Anstis & Saida, 1985) and that its biasing effects decays over several seconds (Beauvois & Meddis, 1997). No study has examined whether the frequency specificity of buildup persists for such a long duration. To address these issues, Experiment 1 tested the decay of frequency-specific and non-frequency specific buildup. The results revealed that (1) frequency-specific buildup effects …

What The Joint Admission Medical Program (Jamp) Can Do For Texas Physicians; What Texas Physicians Can Do For Jamp - See More At: Http://Www.Texmed.Org/Aug12journal/#Sthash.M6pv8cjh.Dpuf, Alan Podawiltz, James Richardson, Wallace Gleason, Kathleen Fallon, David Jones, Elizabeth Peck, Jeffrey Rabek, Manuel Schydlower, William Thomson, Russell Warne, Budge Mabry, Paul Hermesmeyer, Quentin Smith

Russell T Warne

Texas faces health challenges requiring a physician workforce with understanding of a broad range of issues – including the role of culture, income level, and health beliefs – that affect the health of individuals and communities. Building on previous successful physician workforce "pipeline" efforts, Texas established the Joint Admission Medical Program (JAMP), a first-of-its-kind program to encourage access to medical education by Texans who are economically disadvantaged. The program benefits those from racial and ethnic minority groups and involves all 31 public and 34 private Texas undergraduate colleges and universities offering life science degrees, as well as all 9 medical …

Bayesian Approaches To Assessing Architecture And Stopping Rule, Joseph W. Houpt, A. Heathcote, A. Eidels, J. T. Townsend

Joseph W. Houpt

Much of scientific psychology and cognitive science can be viewed as a search to understand the mechanisms and dynamics of perception, thought and action. Two processing attributes of particular interest to psychologists are the architecture, or temporal relationships between sub-processes of the system, and the stopping rule, which dictates how many of the sub-processes must be completed for the system to finish. The Survivor Interaction Contrast (SIC) is a powerful tool for assessing the architecture and stopping rule of a mental process model. Thus far, statistical analysis of the SIC has been limited to null-hypothesis- significance tests. In this talk …

Motivated Reasoning, Political Sophistication, And Associations Between President Obama And Islam, Todd K. Hartman, Adam J. Newmark

Todd K. Hartman

Recent polls reveal that between 20% and 25% of Americans erroneously indicate that President Obama is a Muslim. In this article, we compare individuals' explicit responses on a survey about religion and politics with reaction time data from an Implicit Association Test (IAT) to investigate whether individuals truly associate Obama with Islam or are motivated reasoners who simply express negativity about the president when given the opportunity. Our results suggest that predispositions such as ideology, partisanship, and race affect how citizens feel about Obama, which in turn motivates them to accept misinformation about the president. We also find that these …

Exploration Of Sensemaking In The Education Of Novices To The Complex Cognitive Work Domain Of Air Traffic Control, Travis J. Wiltshire

Doctoral Dissertations and Master's Theses

Many current complex business and industry jobs consist primarily of cognitive work; however, current approaches to training may be inadequate for this type of work (Hoffman, Feltovich, Fiore, Klein, & Ziebell, 2009). To try and improve training and education for cognitive work, Klein and Baxter (2006) have proposed cognitive transformation theory (CTT), a learning theory that claims that sensemaking activities are essential for acquiring expertise that is adaptive and thus well suited for cognitive work domains. In the present research, cognitive task analysis methods were used to identify and assess sensemaking support in the instruction and learning of complex concepts …

Hypertension And Cognitive Functioning: A Perspective In Historical Context, Merrill F. Elias, Amanda L. Goodell, Gregory A. Dore

Maine-Syracuse Longitudinal Papers

Our objective is to characterize the development of the literature on hypertension and cognitive functioning from a historical perspective. This goal was stimulated by the review on “Historical Trends and Milestones in Hypertension Research” in the October 2012 issue of Hypertension. Our specific aims are threefold: (1) to trace and describe the history of this area of research; (2) to identify milestones in knowledge and methods; and (3) to discuss briefly how this literature translates into patient care. The topic is of major relevance to research and practice because hypertension is a well-known risk factor for decline in cognitive performance …
