Multilingualism And Memory: Investigating Possible Differences In The Abilities Of Monolingual And Multilingual College Students, Clara E. Barned Dec 2022

Multilingualism And Memory: Investigating Possible Differences In The Abilities Of Monolingual And Multilingual College Students, Clara E. Barned

Honors Projects

This study investigated whether there is a difference in the memories of monolingual and multilingual undergraduate students using simple memorization tasks. There were 46 participants, 30 of which were monolingual (only knew one language) and 16 of which were multilingual (knew two or more languages). There was found to be no significant difference between the performance of the two groups, with the data generating a p-value of 0.557. This study further suggests related avenues of research and ways in which the study could be improved in the future.

Psychology Faculty Articles and Research

Exposure to early life adversity has long term consequences on cognitive function. Most research has focused on understanding components of early life adversities that contribute to later risk, including poverty, trauma, maltreatment, and neglect. Whereas these factors, in the aggregate, explain a significant proportion of emotional and cognitive problems, there are serious gaps in our ability to identify potential mechanisms by which early life adversities might promote vulnerability or resilience. Here we discuss early life exposure to unpredictable signals from the caretaker as an understudied type of adversity that is amenable to prevention and intervention. We employ a translational approach …


An Innocent Bystander Walks Into A Bar: The Influence Of Temporal Proximity And Familiarity On Unconscious Transference, Nia Gipson Aug 2022

An Innocent Bystander Walks Into A Bar: The Influence Of Temporal Proximity And Familiarity On Unconscious Transference, Nia Gipson

Graduate Theses and Dissertations

According to The Innocence Project, 69% of DNA exonerations in the United States involved mistaken eyewitness identification as a contributing factor to these errant convictions. Psychologists have contributed towards minimizing mistaken identifications by proposing best practices that law enforcement still follow today. One understudied cause of mistaken eyewitness identification is unconscious transference (UT). UT is a memory error in which a person encountered in an innocent context becomes confused with a person seen in a guilty context (Loftus, 1976). Past research has established some boundary conditions for when UT can occur; however, the limited methodology has resulted in narrow conclusions …


Effects Of Music Exposure On Autobiographical Memory In Alzheimer's Patients: A Systematic Review And Meta-Analysis, Gregory Vance May 2022

Effects Of Music Exposure On Autobiographical Memory In Alzheimer's Patients: A Systematic Review And Meta-Analysis, Gregory Vance

Honors Theses

The progression of Alzheimer’s disease is primarily characterized by a loss of memory concerning past events, as well as a lack in ability to create new memories. While this spans across many subsets of memory, such as recognition, recall, and autobiographical memory, there seems to be a lesser impact on musical memory in those with Alzheimer’s. Multiple studies have suggested that exposure to music and introduction of music therapy can even improve other aspects of memory in Alzheimer’s patients. This systematic review and meta-analysis sought to examine the relationship between music exposure and autobiographical memory specifically. A pool of electronic …


Mental Construal And Alterations In Emotional Memory, Olivia D. Beers Feb 2022

Mental Construal And Alterations In Emotional Memory, Olivia D. Beers

Dissertations

Psychological distancing refers to a shift from a psychologically immersed perspective that involves thinking about the details of an event (concretely) or stepping back from it and watching the event from an outside point of view (abstractly)––this can help individuals change how they feel about the experience. Investigating how construal levels affect emotional memories may provide more insight into how individuals may potentially alter the recall of their memories. The current study reflects a new examination of the effect of primed high and low construal levels on the recall of positive and negative arousing stimuli. This study included a pilot …

Does Quran Memorization Influence Adolescents’ Intelligence Quotient And Memory Level?: A Cross-Sectional Study In Malaysia, Ismarulyusda Ishak, Amira Aqilah Shaidin, Dzalani Harun, Nor Malia Abdul Warif, Vanitha Mariappan, Arimi Fitri Mat Ludin, Ahmad Rohi Ghazali, Farah Wahida Ibrahim, Normah Che Din

Makara Journal of Health Research

Background: The process of memorizing various reading materials enhances the brain capacity to process, store, and assemble memories and increases the intelligence quotient (IQ) level. However, the connection between the memorization of Quran and the enhancement of memory level is not fully understood. Hence, a cross-sectional study was conducted to examine the correlation between Quran memorization and the IQ level among Muslim adolescents from selected Islamic schools in Selangor, Malaysia.

Methods: The Wechsler Abbreviated Scale of Intelligence was used to measure the student’s IQ level, whereas Digit Span and Rey Auditory Verbal Learning Test were used to evaluate …


Exploring Attentional And Emotional Biases As A Function Of Trauma And Dissociation Symptomology, Claudia Clinchard Mar 2021

Exploring Attentional And Emotional Biases As A Function Of Trauma And Dissociation Symptomology, Claudia Clinchard

Department of Psychology: Dissertations, Theses, and Student Research

There is evidence that threatening facial expressions (e.g., angry faces) direct attention toward the target, and that for facial expressions that are less threatening but still convey negative valence (e.g., fear faces) direct attention outward and to one’s environment, therefore causing a shift in memory performance and attentional bias depending on the level of threat in emotional facial expressions presented. Extant literature provides evidence for attentional biases both towards and away from threat in those with posttraumatic stress disorder (PTSD) symptomology. The current study aimed to replicate the previous findings of the effects stimulus and emotion have on memory performance …


Learning Without Contingencies Induces Higher Order Asynchrony In Brain Networks In Schizophrenia, Elizabeth L. Martin, Asadur Chowdury, Vaibhav Diwadkar, Sazid Hasan, Munajj Ul-Huq, Shahira Baajour, Dalal Khatib, Usha Rajan, Jeffrey Stanley Feb 2021

Learning Without Contingencies Induces Higher Order Asynchrony In Brain Networks In Schizophrenia, Elizabeth L. Martin, Asadur Chowdury, Vaibhav Diwadkar, Sazid Hasan, Munajj Ul-Huq, Shahira Baajour, Dalal Khatib, Usha Rajan, Jeffrey Stanley

Medical Student Research Symposium

Schizophrenia (SCZ) is characterized by both cognitive and reward impairments. A recent study suggests that SCZ is associated with a loss of synchrony between learning and reward circuits (Robison et al., 2019) and higher levels of dis-organization of functional brain networks may underpin failures in learning that characterize SCZ (Hütt et al., 2014). Therefore, here we examined inter-group (HC ≠ SCZ) 4th order differences in statistical regularity across a connectome of cognition and reward brain circuits. The analyses were conducted on fMRI time series data from a previous learning paradigm (Stanley et al., 2017) with periods of Encoding and …


Core Neuropsychological Measures For Obesity And Diabetes Trials: Initial Report, Kimberlee D'Ardenne, Cary R. Savage, Dana Small, Uku Vainik, Luke E. Stoeckel Sep 2020

Core Neuropsychological Measures For Obesity And Diabetes Trials: Initial Report, Kimberlee D'Ardenne, Cary R. Savage, Dana Small, Uku Vainik, Luke E. Stoeckel

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Obesity and diabetes are known to be related to cognitive abilities. The Core Neuropsychological Measures for Obesity and Diabetes Trials Project aimed to identify the key cognitive and perceptual domains in which performance can influence treatment outcomes, including predicting, mediating, and moderating treatment outcome and to generate neuropsychological batteries comprised of well-validated, easy-to-administer tests that best measure these key domains. The ultimate goal is to facilitate inclusion of neuropsychological measures in clinical studies and trials so that we can gather more information on potential mediators of obesity and diabetes treatment outcomes. We will present the rationale for the project and …


Males With Chronic Ankle Instability Demonstrate Deficits In Neurocognitive Function Compared To Control And Copers, Adam B. Rosen, Melanie L. Mcgrath, Arthur C. Maerlender Jan 2020

Males With Chronic Ankle Instability Demonstrate Deficits In Neurocognitive Function Compared To Control And Copers, Adam B. Rosen, Melanie L. Mcgrath, Arthur C. Maerlender

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

The purpose of this study was to determine if there were neurocognitive deficits among controls, copers and those with chronic ankle instability (CAI). Participants included those without history of ankle injury (n = 14), ankle sprain copers (n = 13) and patients with self-reported CAI (n = 14). They completed a battery of valid and reliable computer-based neurocognitive tests. The differences between neurocognitive domain scores were compared across the Control, Coper and CAI groups. Patients with CAI had lower composite memory, visual memory and simple attention compared to controls. In males with CAI, large differences in memory and attention were …


What Makes An Image Memorable? Effects Of Encoding On The Mechanism Of Recognition, Asiya Gul Jan 2020

What Makes An Image Memorable? Effects Of Encoding On The Mechanism Of Recognition, Asiya Gul

Theses and Dissertations (Comprehensive)

Memory is undoubtedly one of the most important processes of human cognition. A long line of research suggests that recognition relies on the assessment of two explicit memory phenomena: familiarity and recollection. Researchers who support the Dual Process Signal Detection (DPSD) model of recognition memory link the FN400 component (a negative ERP deflection peaking around 400 ms at frontal electrodes) with familiarity; however, it is currently unclear whether the FN400 reflects familiarity or implicit memory. Three event-related potentials (ERP) studies were conducted to determine whether implicit memory plays a role in setting up encoding strategies, and how these encoding strategies …


Does Aerobic Exercise Or Cardiovascular Exercise Facilitate Explicit Memory?, Nicole Paige Ellin Jan 2019

Does Aerobic Exercise Or Cardiovascular Exercise Facilitate Explicit Memory?, Nicole Paige Ellin

Senior Projects Spring 2019

This study examined whether cardiovascular or aerobic exercise aids in explicit memory. Five male and twenty-four females on the Bard College campus either engaged in cardiovascular or aerobic exercise (experimental condition) or watched a video (control condition). Before beginning these tasks, participants read a list of 15 words. After the task, participants recalled as many words as they could from the previous list. The participants’ test scores did not indicate that a specific condition aided in their received score, meaning memory did not differ across conditions, F(2,29)= .420, p>.05. Future directions would implement a longer period of time for …


What U.S Defense Attorneys Know About Facial Composites, Marisa H. Jaross May 2018

What U.S Defense Attorneys Know About Facial Composites, Marisa H. Jaross

Student Theses

The Innocence Project’s DNA exoneration database (2018) indicates that approximately 27% of wrongful conviction cases containing eyewitness evidence also included a composite or sketch[1] of the perpetrator. This statistic is alarming, given that composites are rarely used in criminal investigations (PERF, 2013), but not surprising considering “good” composites are notoriously difficult to construct (e.g., Wells, Charman, & Olson, 2005). It is well understood that eyewitness evidence can be particularly persuasive evidence of guilt for juries and thus we were interested in learning more about how defense attorneys prepare for trial with respect to this specific type of eyewitness evidence. …


Nyx-2925 Is A Novel Nmda Receptor-Specific Spirocyclic-Beta-Lactam That Modulates Synaptic Plasticity Processes Associated With Learning And Memory, M. Amin Khan, David R. Houck, Amanda L. Gross, Xiao-Lei Zhang, Cassia Cearley, Patric K. Stanton, Joseph R. Moskal Mar 2018

Nyx-2925 Is A Novel Nmda Receptor-Specific Spirocyclic-Beta-Lactam That Modulates Synaptic Plasticity Processes Associated With Learning And Memory, M. Amin Khan, David R. Houck, Amanda L. Gross, Xiao-Lei Zhang, Cassia Cearley, Patric K. Stanton, Joseph R. Moskal

NYMC Faculty Publications

Background: N-methyl-D-aspartate receptors are one member of a family of ionotropic glutamate receptors that play a pivotal role in synaptic plasticity processes associated with learning and have become attractive therapeutic targets for diseases such as depression, anxiety, schizophrenia, and neuropathic pain. NYX-2925 ((2S, 3R)-3-hydroxy-2-((R)-5-isobutyryl-1-oxo-2,5-diazaspiro[3.4]octan-2-yl)butanamide) is one member of a spiro-beta-lactam-based chemical platform that mimics some of the dipyrrolidine structural features of rapastinel (formerly GLYX-13: threonine-proline-proline-threonine) and is distinct from known N-methyl-D-aspartate receptor agonists or antagonists such as D-cycloserine, ketamine, MK-801, kynurenic acid, or ifenprodil. Methods: The in vitro and in vivo pharmacological properties of NYX-2925 were examined. Results: NYX-2925 has …

Word-List Intrusion Errors Predict Progression To Mild Cognitive Impairment, Kelsey R Thomas, Joel Eppig, Emily C Edmonds, Diane M Jacobs, David J Libon, Rhoda Au, David P Salmon, Mark W Bondi, Alzheimer’S Disease Neuroimaging Initiative

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship

OBJECTIVE: Preclinical Alzheimer's disease (AD) defined by a positive AD biomarker in the presence of normal cognition is presumed to precede mild cognitive impairment (MCI). Subtle cognitive deficits and cognitive inefficiencies in preclinical AD may be detected through process and error scores on neuropsychological tests in those at risk for progression to MCI.

METHOD: Cognitively normal participants (n = 525) from the Alzheimer's Disease Neuroimaging Initiative were followed for up to 5 years and classified as either stable normal (n = 305) or progressed to MCI (n = 220). Cox regressions were used to determine whether baseline process scores on …


Memory In Memoir & Biography: Science, Place, And Agency, Johnathan E. Longo Feb 2018

Memory In Memoir & Biography: Science, Place, And Agency, Johnathan E. Longo

Dissertations, Theses, and Capstone Projects

This thesis explores modern scientific understanding of memory in humans and how it affects works of life writing. Scientific research shows that memory is unreliable and often misunderstood by the general public, and this has implications for different forms of life writing. This paper uses biographies, memoirs, and hybrid forms of life writing to explore how memory, with all its limitations, is used in service of a life story. How do writers of these sub-genres use memory and why are those strategies different from one another? Questions of agency and authority over written and spoken material make the issues still …

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship

BACKGROUND: Working memory (WM) is often assessed with serial order tests such as repeating digits backward. In prior dementia research using the Backward Digit Span Test (BDT), only aggregate test performance was examined.

OBJECTIVE: The current research tallied primacy/recency effects, out-of-sequence transposition errors, perseverations, and omissions to assess WM deficits in patients with mild cognitive impairment (MCI).

METHODS: Memory clinic patients (n = 66) were classified into three groups: single domain amnestic MCI (aMCI), combined mixed domain/dysexecutive MCI (mixed/dys MCI), and non-MCI where patients did not meet criteria for MCI. Serial order/WM ability was assessed by asking participants to repeat …


Development Of Ethologically-Based Inhibitory Avoidance Models Of Fear Memory, Savannah Dalrymple Jun 2017

Development Of Ethologically-Based Inhibitory Avoidance Models Of Fear Memory, Savannah Dalrymple

USF Tampa Graduate Theses and Dissertations

Translational research provides a unique opportunity to investigate innate and conditioned fear to develop an integrated understanding of anxiety disorders, ultimately improving treatment for those afflicted. Many fear conditioning paradigms use physically aversive stimuli to induce fear but ethological stimuli may better represent psychological disorders from a translational standpoint. Natural predators and immobilization have been successful in inducing both innate and contextually conditioned fear in rodents but an inhibitory avoidance paradigm that uses ethologically relevant stimuli has yet to be developed. To expand the use of these stimuli into inhibitory avoidance conditioning, an inhibitory avoidance paradigm was developed to include …


Sensation Seeking Impact On Skin Conductance Measures Of Deception And Memory, Andrew David Manson, Suzanna Lagerroos, Phillip Janz, Adam Lawson, Jonathan Gore Jun 2017

Sensation Seeking Impact On Skin Conductance Measures Of Deception And Memory, Andrew David Manson, Suzanna Lagerroos, Phillip Janz, Adam Lawson, Jonathan Gore

EKU Faculty and Staff Scholarship

We sought to determine whether sensation seeking would differentially predict measures of memory and deception (concealing information) as indexed by behavioral (response time, accuracy) and autonomic (skin conductance level) markers in a sample of college students. Participants were randomly assigned to a mock-crime group or an innocent-errand group. Both groups were trained to complete a task requiring the copying of documents from a secure location; the difference was the mock-crime group broke into the office whereas the errand group was given permission to enter the room and access the documents. After being trained to perform the crime or errand task, …


Functional Human Grin2b Promoter Polymorphism And Variation Of Mental Processing Speed In Older Adults, Yang Jiang, Ming Kuan Lin, Gregory A. Jicha, Xiuhua Ding, Sabrina L. Mcilwrath, David W. Fardo, Lucas S. Broster, Frederick A. Schmitt, Richard J. Kryscio, Robert H. Lipsky Apr 2017

Functional Human Grin2b Promoter Polymorphism And Variation Of Mental Processing Speed In Older Adults, Yang Jiang, Ming Kuan Lin, Gregory A. Jicha, Xiuhua Ding, Sabrina L. Mcilwrath, David W. Fardo, Lucas S. Broster, Frederick A. Schmitt, Richard J. Kryscio, Robert H. Lipsky

Behavioral Science Faculty Publications

We investigated the role of a single nucleotide polymorphism rs3764030 (G > A) within the human GRIN2B promoter in mental processing speed in healthy, cognitively intact, older adults. In vitro DNA-binding and reporter gene assays of different allele combinations in transfected cells showed that the A allele was a gain-of-function variant associated with increasing GRIN2B mRNA levels. We tested the hypothesis that individuals with A allele will have better memory performance (i.e. faster reaction times) in older age. Twenty-eight older adults (ages 65-86) from a well-characterized longitudinal cohort were recruited and performed a modified delayed match-to-sample task. The rs3764030 polymorphism was …


Prevention Of Recurrent Affective Episodes Using Extinction Training In The Reconsolidation Window: A Testable Psychotherapeutic Strategy., Robert M Post, Robert Kegan Mar 2017

Prevention Of Recurrent Affective Episodes Using Extinction Training In The Reconsolidation Window: A Testable Psychotherapeutic Strategy., Robert M Post, Robert Kegan

Psychiatry and Behavioral Sciences Faculty Publications

Stressors may initially precipitate affective episodes, but with sufficient numbers of recurrences, episodes can occur more autonomously. It is postulated the memory engram for these recurrent depressions moves from the conscious representational memory system to the unconscious habit memory system encoded in the striatum. If this were the case, cognitive behavior therapy targeted toward extinction of habit memories could be an effective maneuver for helping reverse the automaticity of affective episode recurrence. Extinction training in the reconsolidation window (which opens about 5 min to 1 h after active memory recall) can revise, reverse, or eliminate the long term memories associated …


A Cognitive Electrophysiological Signature Differentiates Amnestic Mild Cognitive Impairment From Normal Aging, Juan Li, Lucas S. Broster, Gregory A. Jicha, Nancy B. Munro, Frederick A. Schmitt, Erin L. Abner, Richard J. Kryscio, Charles D. Smith, Yang Jiang Jan 2017

A Cognitive Electrophysiological Signature Differentiates Amnestic Mild Cognitive Impairment From Normal Aging, Juan Li, Lucas S. Broster, Gregory A. Jicha, Nancy B. Munro, Frederick A. Schmitt, Erin L. Abner, Richard J. Kryscio, Charles D. Smith, Yang Jiang

Behavioral Science Faculty Publications

Background: Noninvasive and effective biomarkers for early detection of amnestic mild cognitive impairment (aMCI) before measurable changes in behavioral performance remain scarce. Cognitive event-related potentials (ERPs) measure synchronized synaptic neural activity associated with a cognitive event. Loss of synapses is a hallmark of the neuropathology of early Alzheimer’s disease (AD). In the present study, we tested the hypothesis that ERP responses during working memory retrieval discriminate aMCI from cognitively normal controls (NC) matched in age and education.

Methods: Eighteen NC, 17 subjects with aMCI, and 13 subjects with AD performed a delayed match-to-sample task specially designed not only to be …


The Effects Of Abilify On Memory, Coordination, And Stereotypy In Cd-1 Mice, Jostein Andersen Jan 2017

The Effects Of Abilify On Memory, Coordination, And Stereotypy In Cd-1 Mice, Jostein Andersen

Undergraduate Honors College Theses 2016-

The atypical antipsychotic Abilify is the second most popular treatment for schizophrenia and other related disorders. Its popularity and wide use is due to its unique pharmacological profile, working differently at dopamine and serotonin receptors compared to other antipsychotics. Schizophrenia is an infamous mental dysfunction involving cognitive impairment, positive symptoms, and negative symptoms. The current study investigated Abilify’s effect in a dose-dependent manner on memory, coordination and stereotypic movement. The sample consisted of 15 male and 15 female CD-1 mice. Memory was tested in a cognitive maze, the Rota-Rod series 8 model measured coordination, and the Coulbourn Tru-Scan Activity Box …


Construct Validity For The Poreh Nonverbal Memory Test On Participants With Right, Left, And Bilateral Temporal Lobe Epilepsy, Sarah E. Tolfo Jan 2017

Construct Validity For The Poreh Nonverbal Memory Test On Participants With Right, Left, And Bilateral Temporal Lobe Epilepsy, Sarah E. Tolfo

ETD Archive

The present study examined the construct validity of a novel nonverbal memory measure, the Poreh Nonverbal Memory Test (PNMT), using a heterogeneous sample of patients with epilepsy. Results from this study shows that the PNMT differentially correlated with existing memory measures. Namely, the PNMT delay scores significantly correlated with ROCF delay scores, and RAVLT delay and ROCF delay scores were significantly correlated with each other. However, the PNMT did not significantly correlate with RAVLT, which was hypothesized. PNMT and RAVLT learning trials produced logarithmic learning curves that indicate both are good measures of learning. When controlling for gender, education, and …


How Best To Study For A Test: A Comparison Of Practice Retrieval And Self-Explanation, Casey Fortney Aug 2016

How Best To Study For A Test: A Comparison Of Practice Retrieval And Self-Explanation, Casey Fortney

Mahurin Honors College Capstone Experience/Thesis Projects

Students often struggle to prepare for their exams, perhaps as a result of using an unhelpful study method. This study compared the effects of using three study methods: rereading, practice retrieval, and self-explanation. 79 college students studied a short science text passage and were tested with both verbatim and inference questions one week later. Students who reread the information did not perform differently from those who practiced retrieving or self-explained the information. Students who self-explained the information performed better on verbatim test questions than those who practiced retrieving the information. Possible explanations for these findings and implications are discussed.


Apolipoprotein E And Clusterin Can Magnify Effects Of Personality Vulnerability On Declarative Memory Performance In Non‐Demented Older Adults, Sharaddha Sapkota, Sandra A. Wiebe, Brent J. Small, Roger A. Dixon May 2016

Apolipoprotein E And Clusterin Can Magnify Effects Of Personality Vulnerability On Declarative Memory Performance In Non‐Demented Older Adults, Sharaddha Sapkota, Sandra A. Wiebe, Brent J. Small, Roger A. Dixon

Aging Studies Faculty Publications

Objectives: Recent research has linked psychological (personality) factors and specific genetic risk polymorphisms to performance on neurocognitive phenotypes. We examined whether episodic or semantic memory performance is associated with (a) three personality traits (i.e. neuroticism, extraversion, and openness to experience), (b) two neurodegenerative‐related polymorphisms (i.e. Apolipoprotein E (APOE; rs7412; rs429358), Clusterin (CLU; rs11136000)), and (c) cross‐domain risk interactions (magnification effects).

Methods: Linear growth models were examined to test independent associations between personality traits and declarative memory performance, and potential interaction effects with APOE and CLU genetic risk. Normal older adults (n = 282) with personality …


Sex Differences In Hiv Effects On Visual Memory Among Substance-Dependent Individuals, Michael K. Keutmann, Raul Gonzalez, Pauline M. Maki, Leah H. Rubin, Jasmin Vassileva, Eileen M. Martin Jan 2016

Sex Differences In Hiv Effects On Visual Memory Among Substance-Dependent Individuals, Michael K. Keutmann, Raul Gonzalez, Pauline M. Maki, Leah H. Rubin, Jasmin Vassileva, Eileen M. Martin

Psychiatry Publications

HIV’s effects on episodic memory have not been compared systematically between male and female substance-dependent individuals. We administered the Brief Visuospatial Memory Test–Revised (BVMT–R) to 280 substance-dependent HIV+ and HIV– men and women. Groups were comparable on demographic, substance use, and comorbid characteristics. There were no significant main effects of sex or HIV serostatus on BVMT–R performance, but HIV+ women performed significantly more poorly on delayed recall. This effect was most prominent among cocaine-dependent HIV+ women. Our findings are consistent with recent speculation that memory impairment may be more common among HIV+ women, particularly those with a history of cocaine …


An Integrative Neurological Model For Basic Observable Human Behavior, Ryan M. Francis Jan 2016

An Integrative Neurological Model For Basic Observable Human Behavior, Ryan M. Francis

Calvert Undergraduate Research Awards

The scientific method uncovers information from the natural world in small increments. This spurs the design of models to explain how the pieces fit together and to identify future targets of research. This is especially the case in psychology, where visualizing concepts is an advantageous practice. One all too common criticism of cognitive and behavioral models in psychology is the lack of a biological basis. This paper aims to alleviate part of this issue by integrating currently understood biological and neurological mechanisms that drive psychological phenomena into a predictive and descriptive model for basic human behavior. To accomplish this task, …


Effect Of Sensory Cues On Hand Hygiene Habits Among A Diverse Workforce In Food Service, Robert Pellegrino May 2015

Effect Of Sensory Cues On Hand Hygiene Habits Among A Diverse Workforce In Food Service, Robert Pellegrino

Graduate Theses and Dissertations

Poor hand hygiene is a leading cause of foodborne illnesses in the foodservice industry. A series of complex motivational interventions must be employed to permanently change the behavior of workers, to increase their compliance and sustain appropriate levels of proper hand hygiene. Unlike the healthcare industry, which uses large, costly multi-modal behavior modification strategies, the foodservice industry must deploy rapid, cost-efficient strategies that are focus on accommodating these goals with the constraints of high employee turnover rates and diverse demographics. This research was twofold, 1) examining differences in emotions and hand hygiene behavior among participants of two cultures when handling …


Hoarding And Emotional Reactivity: The Link Between Negative Emotional Reactions And Hoarding Symptomatology, A. M. Shaw, K. R. Timpano, G. Steketee, D. F. Tolin, Randy O. Frost Apr 2015

Hoarding And Emotional Reactivity: The Link Between Negative Emotional Reactions And Hoarding Symptomatology, A. M. Shaw, K. R. Timpano, G. Steketee, D. F. Tolin, Randy O. Frost

Psychology: Faculty Publications

Hoarding disorder (HD) is characterized by difficulty discarding, clutter, and frequently excessive acquiring. Theories have pointed to intense negative emotional reactions (e.g., sadness) as one factor that may play a critical role in HD's etiology. Preliminary work with an analogue sample indicated that more intense negative emotions following emotional films were linked with greater hoarding symptoms. Symptom provocation imaging studies with HD patients have also found evidence for excessive activation in brain regions implicated in processing emotions. The current study utilized a sample with self-reported serious hoarding difficulties to examine how hoarding symptoms related to both general and hoarding-related emotional …
