Sustained Neural Activity Correlates With Rapid Perceptual Learning Of Auditory Patterns, Björn Herrmann, Kurdo Araz, Ingrid S. Johnsrude

Brain and Mind Institute Researchers' Publications

Repeating structures forming regular patterns are common in sounds. Learning such patterns may enable accurate perceptual organization. In five experiments, we investigated the behavioral and neural signatures of rapid perceptual learning of regular sound patterns. We show that recurring (compared to novel) patterns are detected more quickly and increase sensitivity to pattern deviations and to the temporal order of pattern onset relative to a visual stimulus. Sustained neural activity reflected perceptual learning in two ways. Firstly, sustained activity increased earlier for recurring than novel patterns when participants attended to sounds, but not when they ignored them; this earlier increase mirrored …

Examining Own-Race Bias: A Cooperation And Memory Study Using Diverse Emojis, Jillian Franks

Theses

Other-race-effect or own-race bias is a well-documented phenomenon in memory. Findings suggest that humans are better at recognizing and remembering faces of their own race than other races. Previous research suggests that these results are due to a lack of interracial contact or exposure to other racial groups. Evidence from previous studies has demonstrated that individuals process own-race faces differently than other-race faces, paying more attention to more salient features that become better encoded. While there is empirical support for both hypotheses, it has yet to be studied if the other-race effect for memory extends to representational human faces, for …

Personality Pathology And Cognitive Aging: The Role Of Interpersonal Stress, Patrick Joseph Cruitt

Arts & Sciences Graduate Student Theses and Dissertations

Research on the relationship between normal-range personality and cognitive aging has demonstrated consistent, but modest, effects. The current investigation seeks to increase our understanding of unhealthy cognitive aging by examining the maladaptive extremes of personality. Borderline and avoidant personality disorder (PD), but not obsessive-compulsive PD, were hypothesized to show prospective associations with cognitive aging. Interpersonal stress was expected to mediate these relationships. The current investigation tested these hypotheses in two longitudinal studies of older adulthood: the Alzheimer’s Disease Research Center cohort (ADRC, N = 434, Mage = 69.95, 56% women) and the St. Louis Personality and Aging Network study (SPAN, …

Interdependence With Our Most Forgetful Elders: Alzheimer's In The Anthropocene, Christine Heller

Electronic Theses and Dissertations

This dissertation uses autoethnography and critical psychological and philosophical theories to explore what people with Alzheimer’s disease teach us about being, forgetting, and dying in the Anthropocene. The author collected personal memory data from her lived experience of being with her mother while she had Alzheimer’s disease, and organized these memories into a series of vignettes. Each vignette was analyzed with critical psychological and philosophical theories to illuminate intersubjective themes of denial, things, ancestors, place, dying, and time. These themes connected the personal to the epochal and articulated the wisdom that our most forgetful elders can share in the Anthropocene, …

Belonging And Bias : How Diatonicity And Response Bias Affect Pitch Memory In A Probe Tone Task, Jeff Bostwick

Legacy Theses & Dissertations (2009 - 2024)

Prior research (e.g., Krumhansl, 1979) using a delayed recognition task has found a memory advantage for standard (to-be-remembered) tones that belong to the key of a tonal context (diatonic tones) over those that do not belong to the key of a tonal context (nondiatonic tones). The advantage is purportedly due to the tonal context differentially supporting diatonic over nondiatonic tones. However, this research confounded a change in pitch with a change in diatonicity, raising the possibility that participants were responding to the diatonicity change rather than relying on memory for the standard tone’s pitch specifically. More recent studies (e.g., Frankland …

The Impact Of Naturalistic Age Stereotype Activation, Carla M. Strickland-Hughes, Robin L. West

Pacific Faculty Work

Almost self-fulfilling, commonly held negative stereotypes about old age and memory can impair older adults’ episodic memory performance, due to age-based stereotype threat or self-stereotyping effects. Research studies demonstrating detrimental impacts of age stereotypes on memory performance are generally conducted in research laboratories or medical settings, which often underestimate memory abilities of older adults. To better understand the “real world” impact of negative age and memory stereotypes on episodic memory, the present research tested story recall performance of late middle-aged and older adults (N = 51) following a naturalistic age stereotype manipulation, wherein every day, newspaper-style materials (comics and puzzles) …

The Importance Of Culture-Fit For Remembering Church Sermons, Emily N. Adkins, Madelyn Mcknight, Jonathan S. Gore

Kentucky Journal of Undergraduate Scholarship

This experiment tested the degree to which culture-fit influences memory for the content of a sermon. We hypothesized that people who read a sermon emphasizing the infallibility of Christian scriptures will remember it more accurately if they have collectivistic rather than individualistic values. In contrast, we hypothesized that people who read a sermon emphasizing the subjectivity of Christian scriptures will remember it more accurately if they have individualistic rather than collectivistic values. Participants (n = 270) were randomly assigned to read either an orthodox- or quest-oriented sermon regarding Peter 1:20-21. They then completed a true-false memory test as to …

Tests Of Sample-Recovery Models Of Cued Recall, Jack Harvey Wilson

Dissertations - ALL

Sample-recovery models are a predominant class of episodic memory models that seek to explain why sometimes the representation of an experienced event is not retrieved or retrieved incorrectly. In these models, a correct retrieval occurs if the correct target item was sampled among the alternative studied item, then recovered correctly. In cued recall, participants output the representation of a single experienced event, a target, given a presented test stimulus and some defined relationship between the stimulus and the target. This relationship depends on the kind of cued recall and can rely on either studied or pre-experimental relationships. Sample-recovery models of …

Memory And Identity: Inter-Generational Resilience And Construction Of Diasporic Identities Among Somali Refugees, Hamida Dahir Sheikh Ahmed

Master's Theses

The violence and displacement many refugees face often create a lifelong trauma that manifests in many ways within themselves, their families, and communities. The Somali refugee community in the United States is no different. Since their resettlement in America started in the 1990s following the civil war, the community has struggled with different manifestations of that trauma; substance abuse and gang violence among the youth, prominence of depression and suicide rates, rise of domestic violence, as well as other direct and indirect results associated with mental health. This is the reality of many refugee and immigrant communities, coming directly from …

Communicating Fragmented Memories: Explorations Of Trauma As Autoethnographic Bridges, Alberta Natasia Adji

Research outputs 2014 to 2021

Through an experience of reading, researching and interacting with people with different cultural backgrounds in academia, I explore autoethnographically how my personal experience can offer a way to contemplate connections and disassociations of cultural memory in relation to the May 1998 Riots of Indonesia. I attempt to show how disruptive events can bring the traumatic memories back into current consciousness both within individual lives and in the challenges that Jakarta as a city has in coming to terms with the dead and raped bodies that were the result of the country’s denial of its practices of violence. Disturbing memories emerge …

Memory For A Familiar And Unfamiliar University Logo, Alicia M. Fels

Seton Hall University Dissertations and Theses (ETDs)

Prior research found that memory is fallible and that memory for common objects is poorly encoded (Brady et al., 2008; Nickerson & Adams, 1979). Participants studied one of the logos and recalled both the familiar and unfamiliar logos. Confidence judgments were collected at pre- and post-recall for both logos. Results suggest that recall changed by study condition and logo type, studying before recall, for both the familiar and the unfamiliar logo, improved recall scores. The results also suggest that confidence judgments changed depending on the logo familiarity and time. Confidence decreased from pre- to post-recall for the familiar logo in …

The Effect Of Headline Manipulation On Memory And Reasoning, Kathryn R. Hogan

Masters Theses, 2020-current

Decades of research have examined misinformation and memory. Recently, studies have demonstrated that misleading headlines can influence the reader’s memory and inferential reasoning. The current study examines how accurate and misleading headlines differentially affect readers’ memory and inferential reasoning for news articles. College students (N = 138) read three articles on various topics (e.g., solitary confinement, stem cell research, and wildfires) and then took a test to assess memory and inferences related to the article. Contrary to previous studies, there was not a difference in memory between accurate and misleading headline conditions across article types. The effect of a …

The Effects Of Interactivity On Memory Relating To Presence In Virtual Environments, Jenny Wong

Psychological Science Undergraduate Honors Theses

The overall effectiveness of virtual environments is often linked to and measured by degrees of presence, commonly defined as the psychological sensation of “being there” (Schubert et al., 1999). Psychologists agree that attention and involvement through interactivity play a role in presence (Hartmann et al., 2015; Schubert et al., 1999; Witmer and Singer, 1998). Because attention is critical in encoding information into memory storage, looking at how memory relates to presence is another topic of interest. In this study, participants (N = 30) played through a 3D virtual reconstruction of a Pompeian house under one of two conditions: free-roam …

Facts From Fiction: Packaging Misinformation, Angel Ray Houts

Graduate Theses and Dissertations

Previous research established that readers learn both accurate and inaccurate information from fictional stories. The current study explored factors that might moderate the impact of misinformation. Participants read fictional stories that contain three assertions; the first two were labeled as set-up assertions, and the last were labeled as the critical assertion. First, there was a manipulation of plausibility of information within the stories by presenting either assertions with truthful information, assertions with small lies (plausible misinformation), or assertions with big lies (implausible misinformation). Second, there was manipulation of reliability of the fictional stories by presenting big lies or truthful information …

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 …

Cognitive-Emotional Processing In Alexithymia: An Integrative Review, Olivier Luminet, Kristy A. Nielson, Nathan Ridout

Psychology Faculty Research and Publications

Alexithymia is a multifaceted personality construct characterised by difficulties identifying one’s feelings and distinguishing them from bodily sensations, difficulties describing one’s feelings to others, and an externally oriented cognitive style. Over the past 25 years, a burgeoning body of research has examined how alexithymia moderates processing at the cognition–emotion interface. We review the findings in five domains: attention, appraisals, memory, language, and behaviours. The preponderance of studies linked alexithymia with deficits in emotion processing, which was apparent across all domains, except behaviours. All studies on behaviours and a proportion of studies in other domains demonstrated emotional over-responding. Analysis at the …

The Rac-Gef Tiam1 Promotes Dendrite And Synapse Stabilization Of Dentate Granule Cells And Restricts Hippocampal-Dependent Memory Functions, Jinxuan Cheng, Federico Scala, Francisco A Blanco, Sanyong Niu, Karen Firozi, Laura Keehan, Shalaka Mulherkar, Emmanouil Froudarakis, Lingyong Li, Joseph G Duman, Xiaolong Jiang, Kimberley F Tolias

Faculty, Staff and Students Publications

The dentate gyrus (DG) controls information flow into the hippocampus and is critical for learning, memory, pattern separation, and spatial coding, while DG dysfunction is associated with neuropsychiatric disorders. Despite its importance, the molecular mechanisms regulating DG neural circuit assembly and function remain unclear. Here, we identify the Rac-GEF Tiam1 as an important regulator of DG development and associated memory processes. In the hippocampus, Tiam1 is predominantly expressed in the DG throughout life. Global deletion of Tiam1 in male mice results in DG granule cells with simplified dendritic arbors, reduced dendritic spine density, and diminished excitatory synaptic transmission. Notably, DG …

Relationship Between Cannabis Use And Immediate, Delayed, And Working Memory Performance Among Older Adults, Madison H. Maynard

Honors Undergraduate Theses

Cannabis is increasingly accessible in the United States for recreational and/or medical use. Additionally, the Baby Boomer birth cohort exhibits a greater prevalence of cannabis use than prior generations of older adults. Past research has most frequently addressed the potential cognitive effects of cannabis use in populations of adolescents and young adults. Some of these studies suggest that cannabis use is chronically associated with worse performance on tasks of verbal working memory and executive functioning, however, due to methodological variation and a wide variety of potential confounds including duration of abstinence and frequency of use, results are still inconclusive. Through …

Trained And Derived Relational Responding, Jonathan D. Sober

Wayne State University Dissertations

Introduction: Persons with preclinical Alzheimer’s disease (AD) show impairments in semantic and associative memory years before the onset of clinical symptoms. However, many tasks used to assess these deficits make use of previously learned stimuli, often within well-established semantic networks that may be more resistant to disease-related changes. No research has been conducted examining trained and derived relational responding (TDRR) in older adults or in the presence of AD risk factors. The purpose of this study was to determine whether a novel TDRR task would be sensitive to age-related and disease-risk cognitive changes. Method: Thirty younger adults and 15 older …

What's In A Chunk? : Investigating Expertise Effects On Memory For Complex Visual Search Targets, Kinnera Savitri Maturi

Legacy Theses & Dissertations (2009 - 2024)

Across two experiments, I examined the extent to which three predictions of the chunking and template framework of expertise generalize to the music-reading domain: 1) Experts show perceptual advantages that allow for superior performance in a domain-specific task; 2) Experts’ can identify familiar patterns, which allow them to rapidly detect relevant regions of a stimulus; and 3) Experts’ superior perceptual abilities are domain-specific. In Study 1, the eye movements of expert musicians and non-musicians were recorded while they searched for a complex visual search target (i.e., a bar of piano sheet music) that was located within a search array (i.e., …

Invariant Structural Features Of Retrograde Amnesia Affected Memory, Daniel K. Burch

Walden Dissertations and Doctoral Studies

Traumatized individuals may use one or several emotional defensive strategies to cope with their experience; one method is via autobiographical amnesia which may influence the efficacy of amnesiac patients’ psychological adjustment during a sensitive period. Little research has addressed the potential of how emotionally invariant structural features may impact the reconsolidation of autobiographical memory, which in turn may support patients to complete successfully psychotherapeutic treatment or intervention. This phenomenological study addressed how lived experiences (i.e., invariant emotional and behavioral conscious states) may play into patients’ transformational memory of some or all of the traumatizing event details. To answer these questions, …

The Internet-Extended Mind: The Psychological Ramifications And Philosophical Implications Of Cognitive Offloading, Gloria Choi

Scripps Senior Theses

In this thesis, I explore the internet-extended mind through both philosophical and psychological lenses in order to investigate the questions “To what extent is the mind extended onto the internet and, more generally, outside our bodies?” and “How will an increasingly internet-extended brain change the ways in which humans communicate, remember, and behave?”. First, I introduce the idea of a mind that extends out into the world, instead of lying solely in the brain. Then, I outline existing research that introduces the challenges and implications of an internet-extended mind in an ever-changing internet landscape. Next, I discuss how the internet …

Chronic Pain, Malingering, And The Word Memory Test, Dawn Marie Emmett Bishop

Walden Dissertations and Doctoral Studies

AbstractThe importance of using scientifically grounded strategies to detect malingering has been established in the literature and past research. Many reliable tools have been established for the detection of malingered neurocognition; however, research on how pain may affect these tools is sparse. The purpose of this study was to investigate the effect of pain on cognitive symptom validity testing and to establish the validity of the Word Memory Test (WMT), a cognitive symptom validity test with good sensitivity and specificity, when the test taker is feigning pain (simulating) or remembering pain. The biopsychosocial model and the gate theory of pain …

Memory Strategy Instruction With Goal-Setting And Positive Feedback: Impact On Memory, Strategy Use, And Task Commitment, Mercedes E. Ball

University of the Pacific Theses and Dissertations

Strategy instruction can improve memory performance, but some training programs are more effective than others. Some scholars propose that a key element to boosting the benefits from training programs is enhancing or emphasizing self-regulatory factors, such as knowledge about memory, beliefs about ability, or motivational factors. Research supporting this claim evidence adds that programs that enhance trainees’ confidence in their abilities improve memory performance and that multifactorial programs are more effective than strategy-training-only programs. Setting performance goals and receiving feedback are two self-regulatory factors known to relate to memory performance that may sometimes be included in some training programs. However, …

Hippocampal Functional Connectivity And Memory Performance After Exercise Intervention In Older Adults With Mild Cognitive Impairment, Junyeon Won, Daniel D. Callow, Gabriel S. Pena, Leslie S. Jordan, Naomi A. Arnold-Nedimala, Kristy A. Nielson, J. Carson Smith

Psychology Faculty Research and Publications

Background:

Exercise training (ET) has neuroprotective effects in the hippocampus, a key brain region for memory that is vulnerable to age-related dysfunction.

Objective:

We investigated the effects of ET on functional connectivity (FC) of the hippocampus in older adults with mild cognitive impairment (MCI) and a cognitively normal (CN) control group. We also assessed whether the ET-induced changes in hippocampal FC (Δhippocampal-FC) are associated with changes in memory task performance (Δmemory performance).

Methods:

32 older adults (77.0±7.6 years; 16 MCI and 16 CN) participated in the present study. Cardiorespiratory fitness tests, memory tasks (Rey Auditory Verbal Learning Test (RAVLT) and …

Young Versus Aged Microbiota Transplants To Germ-Free Mice: Increased Short-Chain Fatty Acids And Improved Cognitive Performance, Juneyoung Lee, Venugopal R Venna, David J Durgan, Huanan Shi, Jacob Hudobenko, Nagireddy Putluri, Joseph Petrosino, Louise D Mccullough, Robert M Bryan

Faculty, Staff and Students Publications

Aging is associated with cognitive decline and decreased concentrations of short-chain fatty acids (SCFAs) in the gut. SCFAs are significant in that they are protective to the gut and other organs. We tested the hypothesis that the aged gut microbiome alone is sufficient to decrease SCFAs in the host and produce cognitive decline. Fecal transplant gavages (FTGs) from aged (18–20 months) or young (2–3 months) male C57BL/6 mice into germ-free male C57BL/6 mice (N = 11 per group) were initiated at ~3 months of age. Fecal samples were collected and behavioral testing was performed over the study period. Bacterial community …

Memory And Stereotypes For Lesbian/Gay Characters, Amber Rose Williams

UNLV Theses, Dissertations, Professional Papers, and Capstones

Stereotype-consistency bias refers to the idea that people tend to remember stereotypical information about others better than non-stereotypical information (Fyock & Stangor, 1994). Limited research has examined how people may use stereotype-consistency bias when recalling information about LGBT characters in narratives (Bellezza & Bower, 1981; Clark & Woll, 1981; McGann & Goodwin, 2007; Snyder & Uranowitz, 1978). This line of research suggests that, instead of genuinely remembering stereotypical information better, participants tended to guess stereotypical answers to questions they do not know. In contrast to those studies, the experiment I conducted for this thesis suggests that heterosexual young adults tend …

An Eeg Study On Loneliness And Recognition Memory, Carmen Jia Wen Chek

Electronic Theses and Dissertations

Loneliness, the perception of unmet social needs, has been shown to relate to recollection-based recognition deficits, but the relationship between loneliness and recognition memory (i.e., recollection and familiarity) has not been thoroughly examined. The current study hypothesized that more lonely individuals would have lower recognition memory performance, specifically recollection, with smaller ERP parietal old-new effects than less lonely individuals. Forty participants, grouped into less (n = 13) and more (n = 9) lonely groups based on their R-UCLA responses, completed an associative memory task. EEG was used to assess recognition memory effects. Results showed no significant difference in …

Impact Of Think/No-Think Paradigm On Memory For Inadmissible Evidence, Catherine Hackett

Student Theses

Jurors are typically not able to disregard inadmissible evidence when asked to do so by judges. Yet, there is no research using the think/no-think paradigm on juror memory, which could be beneficial for trials in which inadmissible evidence is an issue. This study uses witness photos and statements to see if the material can be intentionally remembered and intentionally forgotten through a think/no-think task in which participants are cued to think about some witness photo/statement combinations and not think about other photo/statement combinations. Participants were responsible for learning pairs of faces and statements of witnesses from an alleged stabbing. After …
