Pre-Report Review Of Body-Worn Camera Footage: An Examination Of Stakeholder Beliefs, Laypeople’S Judgments Of Officer Credibility, And The Consequences For Memory, Kristyn A. Jones

Dissertations, Theses, and Capstone Projects

Aim: This dissertation examines people’s beliefs about police officer access to body-worn camera footage, people’s judgments of officer credibility as it relates to video footage, and the consequences that review of footage has on reporting accuracy.

Rationale: With escalating police-civilian tensions in 2014, American police departments adopted body-worn camera programs. A majority of departments have policies allowing officers unrestricted access to camera footage. Because officers fear that inconsistencies between reports and videos could result in suspicion of officer deceit, they argue that officers should have access to footage before writing their reports to ensure reports match the footage. Yet, because …

Dynamic Changes In Eeg Power Spectral Densities During Nih-Toolbox Flanker, Dimensional Change Card Sort Test And Episodic Memory Tests In Young Adults, Judith G. Foy, Michael R. Foy

Psychological Science Faculty Works

Much is known about electroencephalograph (EEG) patterns during sleep, but until recently, it was difficult to study EEG patterns during conscious, awake behavior. Technological advances such as powerful wireless EEG systems have led to a renewed interest in EEG as a clinical and research tool for studying real-time changes in the brain. We report here the first normative study of EEG activity while healthy young adults completed a series of cognitive tests recently published by the National Institutes of Health Toolbox Cognitive Battery (NIH-TCB), a commonly-used standardized measure of cognition primarily used in clinical populations. In this preliminary study using …

Effects Of Emotional Valence And Depth Of Processing On Memory, Lauren Tyndall, Matthew Murphy

Honors Theses

This study looks at the relationship between emotionally charged words and the depth at which information is processed and how this relationship affects memory. It is predicted that emotional stimuli make the depth of processing process easier, resulting in emotionally charged words being recalled most frequently. Participants were presented with stimuli using a word task and then took a memory test. Responses to the memory test were measured via Qualtrics. Due to small sample size, the results did not conclusively indicate whether or not emotional valence and depth of processing interact to affect memory. There was no significant interaction between …

The Roots Of Wellbeing: Positive Effects Of Nature Writing, Grace Turner

Honors Theses

Fostering healthy relationships between humans and the environment is beneficial for people and for the natural world around us. Efforts to foster these relationships are more important now than ever before due to the rapid deterioration of the climate and the growing divide between people and nature. There is abundant research documenting the positive physical, psychological, and social effects of time spent in nature, such as positive mood, life satisfaction, connection to nature, pro-environmental behavior, and feelings of transcendence. However, actual experiences in nature may be inconvenient, inaccessible, or otherwise unavailable. Addressing this concern, researchers are now examining the possible …

The Effects Of Antibiotics And Probiotics On Memory And Depression Across Age Groups, Amanda Powell

Masters Theses, 2020-current

The gut-brain axis is a bidirectional pathway that acts as a connection between the gut and the brain. Bacterial changes in the gut alter this pathway, affecting organism’s health, cognition, and behavior. Commensal bacteria in the gut can reduce inflammation and increase longevity while pathogenic bacteria can have opposite effects. Reduced commensal gut bacteria can result in an increase in stress activation, depression, and anxiety in both human and animal models. Increases in commensal bacteria and decreases in pathobiontic bacteria can decrease hypothalamic pituitary adrenal (HPA) system activation, anxious behavior, and depressive behavior. Alternatively, increases in pathobionts can lead to …

Investigating A Self-Reference Effect In Musical Aesthetics, Anna Kasdan, Amy M. Belfi

Psychological Science Faculty Research & Creative Works

Previous work on aesthetic experience suggests that aesthetic judgments are self-referential. The self-reference effect (SRE) is the tendency for individuals to show improved memory for items that are judged in relation to themselves. The current study sought to understand if the SRE exists for aesthetic judgments of music. Participants heard musical excerpts (classical, jazz, and electronic) and rated either a) how much they liked the music (Self condition), b) how much a close relative or friend would like the music (Other condition), or c) the genre of the music (Genre condition). After a retention interval, participants completed a recognition memory …

Investigating The Modulatory Effect Of Expectations On Memory Retrieval During Sentence Comprehension, Luca Campanelli

Dissertations, Theses, and Capstone Projects

Memory retrieval and probabilistic expectations are recognized factors in sentence comprehension that capture two different critical aspects of processing difficulty: the cost of retrieving and integrating previously processed elements with the new input words and the cost of incorrect predictions about upcoming words or structures in a sentence. Although these two factors have independently received substantial support from the extant literature, how they interact remains poorly understood. This study investigated memory retrieval, more specifically retrieval interference, and lexical-semantic expectations in three reading experiments, pitting these factors against each other to observe how they interact. Overall, results showed that retrieving and …

Remember That Party Last Night? Examining The Effects Of Binge-Like Alcohol On Memory, Anna Thomas

Undergraduate Honors Thesis Collection

Alcohol is a widely available drug that is often abused. Studies have shown alcohol-induced memory loss in humans and animals; however, the large amount of alcohol often necessary to observe such loss and use of involuntary drinking paradigms in animals makes translation difficult. The current study was designed to look at voluntary binge-like drinking behavior and memory in rodents. We anticipated decreases in working memory function following consumption of binge-like alcohol in mice and expected a greater deficit in mice experiencing acute withdrawal during the memory task. The present study explored drinking behaviors in adult C57BL/6J mice (18 male, 18 …

Do Distractor Suppression And Learning Intentionality Contribute To The Attentional Boost Effect?, Stephanie C. Crocco

Legacy Theses & Dissertations (2009 - 2024)

In the Attentional Boost Effect (ABE), a target-detection response enhances memory for simultaneously presented unrelated stimuli (Swallow & Jiang, 2010; see Swallow & Jiang, 2013 for a review). In two experiments, participants read aloud words simultaneously presented with a dot. Trials were presented every 1150 ms (Experiment 1) or every 2200 ms (Experiment 2). In a divided attention (DA) task, participants made a key-press to dots of a specific color. In a full attention (FA) task, they only read the words aloud while ignoring all dots. Under either intentional or incidental learning instructions, the DA task included Target words, and …

Integrated Care For Older Adults And Memory: A Quality Improvement Approach, Haley E. Curt

Antioch University Dissertations & Theses

Integrated care, a combination of medical and behavioral health, is necessary to address the complex needs of the rapidly growing population of adults over the age of 65 (Karel, Gratz, & Smyer, 2012). Cognitive impairment, a common issue associated with aging, is a major concern for aging adults, their caregivers and family members. Comprehensively addressing cognition, whether there is an identified impairment or not, in a primary care setting allows the individual to take advantage of their independence, be an active member of planning care and making decisions, and begin treating their disease earlier when it is more manageable (Callahan …

Music On The Brain, Skyler Bortz

Williams Honors College, Honors Research Projects

Music surrounds us in our daily lives through the radio, social media, and our own personal playlists. Taste in music varies across individuals and cultures, but it is a singular, uniting aspect of society. Music creates connections and meaning that would be lost if the first string of an instrument had not been heard. Creativity is sparked with music which adds to the artistry of cultures and other forms of art.

As music develops artistry, so does dance. Music led movement to begin as dance developed through the centuries. While movement can occur in silence, it becomes more impactful when …

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 …

Affective Misattribution Following Memory Decisions Does Not Transfer To Interleaved Items, David Grybinas

Arts & Sciences Graduate Student Theses and Dissertations

The outcomes of memory search appear to have affective consequences. For instance, during recognition memory tests, concluding that a retrieval probe is from a prior study period (‘old’) leads to higher pleasantness ratings for the probe than concluding it is novel (‘new”). Grybinas, Kantner, and Dobbins (2019) explained this and related findings via a Confirmation of Search (COS) hypothesis that assumes that the affective consequences of successful versus failed episodic retrieval are misattributed to probes used to elicit memory search. While these affective misattributions clearly occur for the memory probes themselves (within-item misattribution), social psychological research has previously shown that …

Accuracy Matters For The Benefits Of Sleep After Retrieval Practice, Steven Dessenberger

Arts & Sciences Graduate Student Theses and Dissertations

Previous research suggests that while sleep and retrieval practice can each improve memory on their own, their benefits cannot be combined to produce an additive effect unless feedback is given during the initial test. These previous findings would seem to support a retrieval-as-consolidation of the testing effect, which states that the benefits of retrieval are the result of memory consolidation, a process that normally occurs during the sleep cycle. The present study sought to determine whether the retrieval-as-consolidation account held true when initial test accuracy was considered as a factor. Using foreign language word pairs, we examined the combined effects …

Anxiety And Its Impact On Memory, Blakeney C. Coleman, Ryan M. Yoder

Honors Theses

From influences on our memories of common words to even eyewitness testimonies, anxiety can shape our view of the world (Amir et al., 1996). Our research attempted to show a relationship between anxiety and its effects as an impact on memory as is supported by the Theory of Attentional Control (Eysenck & Calvo, 1992). A video from Simons’ and Chabris’ (1999) study on Inattentional Blindness was used to assess whether anxiety is adaptive or maladaptive to functions of our memory. Our study did not find significance regarding the impact of anxiety on memory. However, the relevance and interest of studies …

A Comparison Of Neural Decoding Methods And Population Coding Across Thalamo-Cortical Head Direction Cells, Zishen Xu, Wei Wu, Shawn S. Winter, Max L. Mehlman, William N. Butler, Christine M. Simmons, Ryan E. Harvey, Laura E. Berkowitz, Yang Chen, Jeffrey S. Taube, Aaron A. Wilber, Benjamin J. Clark

Dartmouth Scholarship

Head direction (HD) cells, which fire action potentials whenever an animal points its head in a particular direction, are thought to subserve the animal’s sense of spatial orientation. HD cells are found prominently in several thalamo-cortical regions including anterior thalamic nuclei, postsubiculum, medial entorhinal cortex, parasubiculum, and the parietal cortex. While a number of methods in neural decoding have been developed to assess the dynamics of spatial signals within thalamo-cortical regions, studies conducting a quantitative comparison of machine learning and statistical model-based decoding methods on HD cell activity are currently lacking. Here, we compare statistical model-based and machine learning approaches …

The Study Of Encoding And Depth Of Learning, Camryn Blauth

Psychology Student Research

This study is looking at how we learn by testing three different levels of encoding. Based on how a word is used the level of encoding changes. In order to test this, three groups were formed based on randomly handing out sheets. Each sheet had a question which required a different level of comprehension. It was a between-subjects design, with self-selecting participants that were mostly 18-year-old female students. The goal of this study was to find out if the more a word is comprehended, or the deeper the encoding, the more likely it is to be able to remember that …

Music And Memory, Stephen Ray, Elizabeth Peters

Psychology Student Research

The study that we are conducting takes a look at how listening to music can affect reading comprehension and memory. Students at Kutztown University will sign up to participate through the SONA System, as well as a few friends participating in the study. We look to place the participants in a room with either playing music or having no music playing. Each participant will be randomly assigned to the condition. The music we will be playing will consist of Billboards Top 10 Songs on a shuffled and repeated playlist. We are using Billboard in order to play relevant music that …

Processing Speed For Action And Semantic Memory, Tyler A. Surber

Master's Theses

Previous research suggests that the processing of affordances may require more perceptually relevant information than words can provide (Surber et al., 2018; Chainay & Humphreys, 2002). The present study investigates this hypothesis with the shoebox task used in Bowers and Turner (2003). A list of 81 object nouns (targets) and associated features (primes: affordance, semantic, and non-associates) was compiled from the McRae, Cree, Seidenberg, and McNorgan (2005) norms. Affordances denote possibilities for action in relation to the object (e.g. chair – sit), whereas semantic features indicate definitional characteristics (e.g. chair – has legs). Affordances and semantic features served as primes …

The Influence Of Neural Reward Processing On Memory In Depression, Nathan M. Hager

Psychology Theses & Dissertations

Theories and research suggest that depression involves impaired reward sensitivity and a deficit in memory for rewarding stimuli. Some researchers propose that this memory deficit may result from reduced neural reward sensitivity, which impairs the encoding of reward-related memories, but few studies have directly probed this connection. Such research may benefit from examining the reward positivity (RewP), an event-related potential (ERP) previously linked to reduced reward sensitivity in depression. Undergraduates with high or low self-reported depression completed a task in which they chose one of three doors, revealing a neutral word written in a color which indicated an outcome of …

Involuntary Memories After Stressor Exposure: Contribution Of Hormonal Status And Rumination In Women., Samantha C. Patton

Electronic Theses and Dissertations

Women experience fewer traumatic stressors over their lifespan than men, but demonstrate a higher prevalence of major depression and stressor-related disorders as a result of trauma exposure (Breslau & Anthony, 2007; Kessler et al., 2005). Differences in prevalence of stressor-related disorders may partially be due to sex-linked vulnerabilities related to emotional memory. Emotion assists in modulation of memory through neurological processes. This modulation enhances memory for emotional stimuli and can lead to a greater frequency of involuntary recall after stressor exposure. This involuntary memory is also a hallmark symptom of Posttraumatic Stress Disorder (PTSD). Sex-linked vulnerabilities, specifically hormonal status and …

Thirty-Five Years Of Computerized Cognitive Assessment Of Aging — Where Are We Now?, Avital Sternin, Alistair Burns, Adrian M. Owen

Brain and Mind Institute Researchers' Publications

Over the past 35 years, the proliferation of technology and the advent of the internet have resulted in many reliable and easy to administer batteries for assessing cognitive function. These approaches have great potential for affecting how the health care system monitors and screens for cognitive changes in the aging population. Here, we review these new technologies with a specific emphasis on what they offer over and above traditional ‘paper-and-pencil’ approaches to assessing cognitive function. Key advantages include fully automated administration and scoring, the interpretation of individual scores within the context of thousands of normative data points, the inclusion of …

Isolating Item And Subject Contributions To The Subsequent Memory Effect, Jihyun Cha

Arts & Sciences Graduate Student Theses and Dissertations

The subsequent memory effect (SME) refers to the greater brain activation during encoding of subsequently recognized items compared to subsequently forgotten items. Previous literature regarding SME has been primarily focused on identifying the role of specific regions during encoding or factors that potentially modulate the phenomenon. The current dissertation examines the degree to which this phenomenon can be explained by item selection effects; that is, the tendency of some items to be inherently more memorable than others. To estimate the potential contribution of items to SME, I provided participants a fixed set of items during encoding, which allowed me to …

Adult And Juvenile Rats Differentially Express Mpfc Glua2 Following Traumatic Memory Retrieval, Edgar Rodriguez

Theses and Dissertations

To advance our understanding of how traumatic memories are modulated between adults and juveniles, we characterize the AMPAr subunits, GluA1, GluA2, GluA3 in the mPFC of rodents following traumatic memory retrieval.

GluA2 was differentially expressed in adults but not juveniles rats. There were no changes in GluA1 or GluA3 expression

Multiple Species Of Distinctiveness In Memory: Separating Task Distinctiveness From Statistical Distinctiveness, Matthew Robert Gretz

Master's Theses

Distinctiveness refers to the memorial benefit of processing unique or item-specific features of a memory set relative to a non-distinctive control. Traditional distinctiveness effects are accounted for based on qualitative differences in how distinctive items are encoded at the time of study. This thesis project aims to evaluate whether a different species of distinctiveness—statistical distinctiveness—may provide a separate contribution to memory beyond traditional encoding-based processes. Statistical distinctiveness refers to the relative frequency with which a specific memory item or set is processed. The current study evaluated statistical distinctiveness through a series of mixed groups in which DRM lists were studied …

Understanding The Effect Of Font Type On Reading Comprehension/Memory Under Time-Constraints, Elizabeth Dressler

Theses/Capstones/Creative Projects

This research study investigated the effects that font type and amount of time had on the reading comprehension. It was predicted that students restricted with time and given difficult-to-read font (Haettenschweiler) would perform more poorly because more cognitive resources are being utilized to decode the typography compared to an easy-to-read font (Times New Roman). Consequently, there would be fewer cognitive resources available to comprehend and remember the material. Previous research has consistently shown that subjects perform better from reading or memorizing words in difficult-to-read font. However, almost all previous research has consisted of short passages, thereby limiting ecological validity. Results …

Attention As A Mechanism For Object-Object Binding In Complex Scenes, Kacie Mennie

LSU Doctoral Dissertations

The current study attempted to determine whether direct binding between objects in complex scenes occurs as a function of directed attention at encoding. In Experiment 1, participants viewed objects in one of these different types contexts: unique scenes, similar scenes, or arrays with no contextual information. Critically, only half of the objects were attended for each encoding trial. Participants then completed an associative recognition task on pairs of items created from the previously studied scenes. Test pairs consisted of two attended or unattended objects, and were associated with a unique scene, a similar scene, or an array. Evidence of binding …

Modeling Melodic Dictation, David John Baker

LSU Doctoral Dissertations

Melodic dictation is a cognitively demanding process that requires students to hear a melody, then without any access to an external reference, transcribe the melody within a limited time frame. Despite its ubiquity in curricula within School of Music settings, exactly how an individual learns a melody is not well understood. This dissertation aims to fill the gap in the literature between aural skills practitioners and music psychologists in order to reach conclusions that can be applied systematically in pedagogical contexts. In order to do this, I synthesize literature from music theory, music psychology, and music education in order to …

Forget Me Not: Are Stronger Memories More Susceptible To Retrieval-Induced Forgetting?, Laura Lee Heisick

LSU Doctoral Dissertations

Successfully retrieving information sometimes causes forgetting of related, but unpracticed, information, termed retrieval-induced forgetting (RIF). One explanatory mechanism of RIF suggests related, but currently irrelevant, information is inhibited during retrieval, resulting in poorer memory for competing representations. Critically, this perspective suggests stronger memories are more susceptible to RIF because stronger representations produce additional competition when unpracticed. To resolve this competition, strong competing items are inhibited, resulting in the counterintuitive prediction that stronger memories are more likely to be forgotten. The aim of the current experiments was to replicate and extend recent work suggesting non-typical objects and own-race faces, both of …
