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 …


Fraternity, Martyrdom And Peace In Burundi: The Forty Servants Of God Of Buta, Jodi Mikalachki Dec 2021

Fraternity, Martyrdom And Peace In Burundi: The Forty Servants Of God Of Buta, Jodi Mikalachki

Journal of Global Catholicism

During Burundi's 1993-2005 civil war, students at Buta Minor Seminary were ordered at gunpoint to separate by ethnicity—Hutus over here, Tutsis over there! They chose instead to join hands and affirm their common identity as children of God. The forty students killed were quickly proclaimed martyrs of fraternity. Their costly solidarity defused the cry for reprisals and continues to inspire Burundians and others on the path of reconciliation. Drawing on fifty interviews with survivors, parents of martyrs, neighbors, religious leaders and other Burundian intellectuals, this essay examines how Burundian Catholics understand the significance of the Buta martyrdom to their …


Arts & Literature: A Review Of The Poetry Book Unburied-Unmarked—The Untold Namibian Story Of The Genocide Of 1904–1908: Pieces And Pains Of The Struggle For Justice, Elise Pape Dec 2021

Arts & Literature: A Review Of The Poetry Book Unburied-Unmarked—The Untold Namibian Story Of The Genocide Of 1904–1908: Pieces And Pains Of The Struggle For Justice, Elise Pape

Genocide Studies and Prevention: An International Journal

Between 1904 and 1908, about eighty per cent of the Herero and fifty per cent of the Nama perished in what is today known as the first genocide of the twentieth century that took place in today’s Namibia under German colonial rule. Over decades, the German government has not officially recognized the genocide as such. Jephta U. Nguherimo is one of the descendants of survivors of this genocide and today lives in the United States. In his poetry book unBuried-unMarked–The unTold Namibian story of the Genocide of 1904-1908: Pieces and Pains of the Struggle for Justice that he has self-published …


Thomas Reid On Language And Mind, Alastair L.V. Crosby Dec 2021

Thomas Reid On Language And Mind, Alastair L.V. Crosby

Electronic Thesis and Dissertation Repository

The dissertation concerns Thomas Reid’s philosophy of language. In the first three chapters, I discuss his philosophy of language in relation to his developmental psychology. More specifically, I discuss his answers to two questions: (i) what does the ability to understand artificial linguistic signs make possible? and (ii) what makes the ability to understand artificial linguistic signs possible? The focus is on Reid’s claim that the mind’s ability to understand artificial linguistic signs makes it possible for it to acquire a number of distinct mental abilities, such as to conceive universals, to judge, and to reason. I argue this claim …


Fun Home: Revelation Of Reality And Relationships Through Grief, Mary Margaret Hughes Dec 2021

Fun Home: Revelation Of Reality And Relationships Through Grief, Mary Margaret Hughes

Belmont University Research Symposium (BURS)

The musical Fun Home by Lisa Kron and Jeanine Tesori follows Alison Bechdel as a child, a young adult, and a grown adult as she looks back on her memories of her deceased father and their relationship as two queer individuals. Alison’s father carries the emotional gravity of the text, driving the scenes forward through the theme of control and the damage it does. Alison and her father both seek to control much of their lives, including their sexualities and subsequent realities about their sexualities. Made clear through a critical analysis of the musical’s plot, character, themes, and language, Fun …

Capstones

On the Cusp film follows the story of Dreamer Erika Apupalo, who immigrated to the United States at the age of 9. Her story is one that represents the determination that Dreamers or DACA-recipients have to achieve the American Dream (freedom), while dealing with the physical limitations of being out of status, and having to deal with the uncertainty of what could happen if she went back to her country. Taking place in 2006 in Tigualo, Ecuador, Erika takes us through her journey of migrating to the United State. “I remember the immigration officer asking me questions”, says Erika, who …


Journo: Organize And Share The Memory Of Travel Experience, Ziyi Tao Dec 2021

Journo: Organize And Share The Memory Of Travel Experience, Ziyi Tao

Theses

With the improvement of living standards and the construction of public transportation, many people travel more frequently. They want to record those experiences and get more enlightenment when they look back upon the memory. Additionally, many people have eagerly requested to share their travel experiences due to the development of social media and the information explosion era. Less than a decade ago, people would travel without a smart device. They tended to take photos along the way with a film camera, and stick them on a physical photo album to share with friends and family. The other traditional method of …


Profile-Guided Data Management For Heterogeneous Memory Systems, Matthew B. Olson Dec 2021

Profile-Guided Data Management For Heterogeneous Memory Systems, Matthew B. Olson

Doctoral Dissertations

Market forces and technological constraints have led to a gap between CPU and memory performance that has widened for decades. While processor scaling has plateaued in recent years, this gap persists and is not expected to diminish for the foreseeable future. This discrepancy presents a host of challenges for scaling application performance, which have only been exacerbated in recent years, as increasing demands for fast and effective data analytics are driving memory energy, bandwidth, and capacity requirements to new heights.

To address these trends, hardware architects have introduced a plethora of memory technologies. For example, most modern memory systems include …


Light Level Intensity Alters Anxiety, But Not Memory, During Open-Field And Novel Object Location Tasks In Male Rats, Angelina Tassone Dec 2021

Light Level Intensity Alters Anxiety, But Not Memory, During Open-Field And Novel Object Location Tasks In Male Rats, Angelina Tassone

Biological Sciences

Appropriate design and control of testing conditions during assessment of animal behavior is critical to maximize generalizability, replicability, and translational relevance. Some sensory stimuli are often controlled: for instance, during rodent behavioral testing, efforts are commonly made to reduce or eliminate olfactory and auditory distractions. However, less attention is paid to the ambient light level intensity (lux), which may vary even between rooms in the same facility. We sought to explore whether behavior is influenced by the standard illumination intensity in one of our behavioral testing rooms. To this end, we measured anxiety-like behaviors, exploration, and spatial memory performance in …

Does Whispering Improve Children’S Memory? Comparing Auditory Vigilance And Salience Hypotheses, Christina M. Barnes Dec 2021

Does Whispering Improve Children’S Memory? Comparing Auditory Vigilance And Salience Hypotheses, Christina M. Barnes

Graduate Theses and Dissertations

Oral communication is one of the primary tools children use to learn new information and speech registers can deliver additional meaning to the words someone uses. Cirillo’s (2004) vigilance hypothesis states “Whispering can affect the psychobiological state of recipients, and in particular raise their auditory vigilance” (Cirillo, 2004, p. 76). Building on this theory, the current study investigates the role of whispering and children’s memory by examining a whispering vigilance, whispering salience which focused on the changes between normal and whisper registers, and combined vigilance and salience hypotheses to determine if whispering contributes to the recall of information. Using video …

Medical Biophysics Publications

Klotho-VS heterozygosity (KL-VShet) is associated with reduced risk of Alzheimer’s disease (AD). However, whether KL-VShet is associated with lower levels of pathologic tau, i.e., the key AD pathology driving neurodegeneration and cognitive decline, is unknown. Here, we assessed the interaction between KL-VShet and levels of beta-amyloid, a key driver of tau pathology, on the levels of PET-assessed neurofibrillary tau in 551 controls and patients across the AD continuum. KL-VShet showed lower cross-sectional and longitudinal increase in tau-PET per unit increase in amyloid-PET when compared to that of non-carriers. This association of KL-VShet on tau-PET was stronger in Klotho mRNA-expressing brain …


Memory Of Wernher Von Braun In Rocket City: The Historians’ Vergangenheitsbewältigung Challenge In Huntsville, Alabama, 1998-2010, Susan Lloyd Mcclamroch Dec 2021

Memory Of Wernher Von Braun In Rocket City: The Historians’ Vergangenheitsbewältigung Challenge In Huntsville, Alabama, 1998-2010, Susan Lloyd Mcclamroch

University of New Orleans Theses and Dissertations

This study investigates the conflict that often develops between historians who aim to reveal difficult history or correct a biased view of history and influential stakeholders who possess the agency to maintain historic silences or a skewed version of history. It examines the case in Huntsville, Alabama, when historians at the University of Alabama Huntsville mounted a campaign to inform the community of World War II events in Europe that preceded the immigration and relocation of a team of German rocketeers to establish a missile development program at the US Army’s Redstone Arsenal facility in 1950. Cold War successes made …


An Erp Study Of The Effects Of Iconic And Nonsense Gestures On Memory Formation, Brianna E. Cairney Nov 2021

An Erp Study Of The Effects Of Iconic And Nonsense Gestures On Memory Formation, Brianna E. Cairney

LSU Master's Theses

Co-speech gesture is an important part of human communication and aids in comprehension, learning, and memory. The addition of iconic gestures to speech has been shown in prior work to enhance memory for the speech. However, it remains unclear as to whether this benefit requires gestures to be meaningful, or, conversely, if any attentionally-engaging gesture will enhance memory. In the current study, we tested two theories to explain the mnemonic benefits of co-speech gesture: Dual Coding Theory, which attributes these benefits to multimodal encoding and enhanced imageability, and Attentional Highlighting Theory, which posits that gestures draw more attention to concurrent …

Identifying The Neurophysiological Effects Of Memory-Enhancing Amygdala Stimulation Using Interpretable Machine Learning, Mohammad S E Sendi, Cory S Inman, Kelly R Bijanki, Lou Blanpain, James K Park, Stephan Hamann, Robert E Gross, Jon T Willie, Babak Mahmoudi

2020-Current year OA Pubs

BACKGROUND: Direct electrical stimulation of the amygdala can enhance declarative memory for specific events. An unanswered question is what underlying neurophysiological changes are induced by amygdala stimulation.

OBJECTIVE: To leverage interpretable machine learning to identify the neurophysiological processes underlying amygdala-mediated memory, and to develop more efficient neuromodulation technologies.

METHOD: Patients with treatment-resistant epilepsy and depth electrodes placed in the hippocampus and amygdala performed a recognition memory task for neutral images of objects. During the encoding phase, 160 images were shown to patients. Half of the images were followed by brief low-amplitude amygdala stimulation. For local field potentials (LFPs) recorded from …


Investigation Of Memory Related Cortical Thalamic Circuitry In The Human Brain, Puck C. Reeders Oct 2021

Investigation Of Memory Related Cortical Thalamic Circuitry In The Human Brain, Puck C. Reeders

FIU Electronic Theses and Dissertations

This dissertation examined the role of medial prefrontal cortex (mPFC) and the hippocampus (HC) in episodic memory, and provides a novel approach to identify the midline thalamus mediating mPFC-HC interactions in humans. The mPFC and HC are critical to the temporal organization of episodic memory, and these interactions are disrupted in several mental health and neurological disorders. In the first study, I provide evidence that the mPFC is involved in ordinal retrieval, and the HC is active in temporal context retrieval in remembering the order of when events happen. In the second study, I focus on the anatomical basis of …


Rumination: Practicing Retrieval Of Autobiographical Memories, Paula T. Hertel, Paola Herrera, Pallavi Shamapant Oct 2021

Rumination: Practicing Retrieval Of Autobiographical Memories, Paula T. Hertel, Paola Herrera, Pallavi Shamapant

Psychology Faculty Research

Background

People who ruminate about negative personal experiences seem to be engaged in practicing retrieval, with the expected consequences of perpetuating those very memories (see Roediger and Butler in Trends Cogn Sci 15:20–27, 2011).

Method

To provide an experimental model of the effect of retrieval practice on subsequent recall of autobiographical memories, we recruited students with low and high scores on the Ruminative Response Scale (Treynor et al. in Cogn Ther Res 27:247–259, 2003), gave them positive and ruminative cues to generate memories, and cued three rounds of practice of half of the memories from each valence.

Results

Control, Alter, And Delete: Investigating The Manipulation Of Memory And Memorial Beliefs By Suspected Psychopaths In Interpersonal Relationships, Kendra Nespoli Oct 2021

Control, Alter, And Delete: Investigating The Manipulation Of Memory And Memorial Beliefs By Suspected Psychopaths In Interpersonal Relationships, Kendra Nespoli

Electronic Theses and Dissertations

Psychopaths are known to wreak havoc in the lives, careers, and relationships of people with whom they come into contact, triggering impacts that can extend for many years. To date, few studies have investigated the psychological tactics used by psychopaths to manipulate and control others in relationships. Previous research in the area of autobiographical memory has demonstrated that the decisions people make regarding belief in their memory for life events are influenced by feedback received from others. Social feedback has been shown to be a powerful influence in persuading others to revise beliefs about past events, particularly in the context …


Impact Of Acetylcholine On Internal Pathways To Basal Amygdala Pyramidal Neurons, Tyler Daniel Anderson-Sieg Oct 2021

Impact Of Acetylcholine On Internal Pathways To Basal Amygdala Pyramidal Neurons, Tyler Daniel Anderson-Sieg

Theses and Dissertations

The basolateral nuclear complex of the amygdala (BNC) – consisting of the lateral (LA), basolateral (BL), and basomedial nuclei (BM) – detects salient environmental stimuli (cue-detection) and motivates appropriate behavioral responses to their implied meaning (cue-guided behavior) via a precise pattern of internal circuitry. Glutamatergic signals representing environmental stimuli enter the LA and split into parallel streams that activate pyramidal neurons (PNs) in the anterior and posterior BL (BLa and BLp), which putatively mediate negative and positive emotions, respectively. The BL is the most densely innervated target of the cholinergic basal forebrain (CBF) and ACh transients (phasic ACh) in cortex …

Sanders-Brown Center on Aging Faculty Publications

Introduction: Alzheimer's disease (AD) neuropathological subtypes (limbic predominant [lpAD], hippocampal sparing [HpSpAD], and typical [tAD]), defined by relative neurofibrillary tangle (NFT) burden in limbic and cortical regions, have not been studied in prospectively characterized epidemiological cohorts with robust cognitive assessments.

Methods: Two hundred ninety-two participants with neuropathologically confirmed AD from the Religious Orders Study and Memory and Aging Project were categorized by neuropathological subtype based on previously specified diagnostic criteria using quantitative regional NFT counts. Rates of cognitive decline were compared across subtypes using linear mixed-effects models that included subtype, time, and a subtype-time interaction as predictors and four cognitive …


The Embroidered Tablecloth: How Locale Influences Eastern European Jewish Textile Production, Elena Solomon Sep 2021

The Embroidered Tablecloth: How Locale Influences Eastern European Jewish Textile Production, Elena Solomon

Electronic Thesis and Dissertation Repository

Recent scholarship frames craft as distinct from art and as an encapsulation of cultural expression at a given moment. Building on that framework, this thesis analyzes the shifting attitudes towards the production of handmade textiles among Eastern European Jews in the US in the twentieth century, as influenced by their migration. To demonstrate the textile environment at that time, this thesis examines pre- and post-migration primary sources and autobiographical writing, including Mary Antin’s The Promised Land, supplemented with interviews of first- and second-generation immigrants to Chicago. In contrast with stereotypes about craft as historically stable, defining craft as regional …


Study Of Primary Cilia In Early Development, Pharmacology, And Brainwave Activity., Matthew Roderick Strobel Sep 2021

Study Of Primary Cilia In Early Development, Pharmacology, And Brainwave Activity., Matthew Roderick Strobel

Doctoral Dissertations

The primary cilium is a unique cellular organelle that emanates from the mother centriole and extends out of the plasma membrane of nearly every mammalian cell. While originally believed to be a vestigial appendage, the cilium is now known to be a signaling hub where various intercellular communication pathways intersect to regulate morphogenesis, proliferation, polarity, differentiation, and homeostasis. Due to their importance in regulating cellular functions the cilium has become a growing focus of biomedical research as it has been linked to at least 35 human developmental disorders which have been termed ciliopathies. In the nervous system, primary cilia regulate …


"Never Forget": Embodied Absence And Extended Relations Of Care After 9/11, Sophie L. Riemenschneider Sep 2021

"Never Forget": Embodied Absence And Extended Relations Of Care After 9/11, Sophie L. Riemenschneider

Dissertations, Theses, and Capstone Projects

This dissertation is a reflection on how loss was articulated in the wake of 9/11. The terror attacks engendered a memorial style that sought to give shape to grief, acknowledging it without filling it in or erasing it. This new style, which I term embodied absence, exists across a range of mediums, from literature to architecture. It is such a potent memorial form because it also captures the traumatic process, which is prolonged, layered, and potentially open-ended. However, despite their ability to mirror the nature of trauma, instances of embodied absence never verbalize the attacks’ root trauma—the disconnect between our …


Sustained Neural Activity Correlates With Rapid Perceptual Learning Of Auditory Patterns, Björn Herrmann, Kurdo Araz, Ingrid S. Johnsrude Sep 2021

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 …


Am I Canadian: Making Canadian History Personally Relevant To Students (And To Me), Melanie V. Williams Aug 2021

Am I Canadian: Making Canadian History Personally Relevant To Students (And To Me), Melanie V. Williams

The Councilor: A National Journal of the Social Studies

This reflection explores the challenges and opportunities inherent in teaching and learning Canadian history when the majority of the learners – and the teacher herself – are first- and second-generation Canadians. The intersectionality and constructed-ness of identity, and the effects of individual versus collective memory on identity, can either alienate students from Canadian history or provide them with a variety of entry points into the subject. Historiography also plays an important role in engaging students in Canadian history, academically as well as personally. Ultimately, what students must learn in history class is the ability to construct Canadian histories that reflect …


Examining Own-Race Bias: A Cooperation And Memory Study Using Diverse Emojis, Jillian Franks Aug 2021

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 …


Memoir Dataset: Quantifying Image Memorability In Adolescents, Gal Almog, Yalda Mohsenzadeh Aug 2021

Memoir Dataset: Quantifying Image Memorability In Adolescents, Gal Almog, Yalda Mohsenzadeh

Undergraduate Student Research Internships Conference

Every day, humans observe and interact with hundreds of images and scenes; whether it be on a cellphone, on television, or in print. Yet a vast majority of these images are forgotten, some immediately and some after variable lengths of time. Memorability is indeed a property intrinsic to all images that can be extracted, as well as predicted. While memory itself is a process that occurs in the brain of an individual, the concept of memorability is an intrinsic, continuous property of a stimulus that can be both measured and manipulated. We selected images from the MemCat data set that …


Personality Pathology And Cognitive Aging: The Role Of Interpersonal Stress, Patrick Joseph Cruitt Aug 2021

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

Arts & Sciences Electronic 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, …


Long-Term Neural Activity Recorders Using Energy-Based Sensing, Compressive Computation And Data Logging, Darshit Mehta Aug 2021

Long-Term Neural Activity Recorders Using Energy-Based Sensing, Compressive Computation And Data Logging, Darshit Mehta

McKelvey School of Engineering Theses & Dissertations

Insects are ideal candidates for developing bio-robotic systems owing to their ability to thrive in almost any environment. For example, neurons in their exquisite olfactory sensory systems can be tapped to create a sensing platform for standoff chemical monitoring. However, for enabling such cyborg systems, it is vital that the neural activity of a freely behaving organism can be measured for long periods of time. The current state-of-the-art neural recording techniques are power-intensive and they either need batteries, which make them too bulky for insects, or they have to maintain a continuous telemetry link to an external power source which …
