The Application Of Bayesian Meta-Analytic Models In Cognitive Research On Neurodevelopmental Disorders, Nic Zapparrata Jun 2024

The Application Of Bayesian Meta-Analytic Models In Cognitive Research On Neurodevelopmental Disorders, Nic Zapparrata

Dissertations, Theses, and Capstone Projects

Meta-analysis is the systematic review and quantitative synthesis of specific areas in literature and is an important quantitative tool for researchers interested in synthesizing a particular body of research. The current research used meta-analysis to investigate processing speed in two neurodevelopmental disorders. This dissertation consisted of four meta-analytic papers. The first paper was a meta-analysis that synthesized a large body of research on processing speed, measured via reaction time (RT) measures, in groups of individuals diagnosed with autism spectrum disorder (ASD) versus age-matched neurotypical comparison groups. This research was motivated by two previous meta-analyses in the literature on processing speed …


What Does It Mean To Be Kindergarten "Ready?": Trends In Parents' Expectations And Families' School Experiences Across Ses, Lisa Babel Jun 2024

What Does It Mean To Be Kindergarten "Ready?": Trends In Parents' Expectations And Families' School Experiences Across Ses, Lisa Babel

Dissertations, Theses, and Capstone Projects

The purpose of this study is to explore the meaning of Kindergarten “ready,” especially as the practice interacts with educational inequity. Past research used secondary data to show that SES relates to the prevalence of redshirting where children’s school entry is delayed by one year with the idea that the older they are when they start school, the more advanced they will be, but studies do not explain why children from families with lower incomes are advised to start Kindergarten later than others (Greensburg & Winsler, 2020; Reardon & Portilla, 2016). Moreover, family expectations of the Kindergarten participation process, including …


Creatively Addressing The Employment Gap: Using Creativity And The Arts To Help Autistic Adolescents And Young Adults Build Skills For Employment, Eliana Rachel Grossman Jun 2024

Creatively Addressing The Employment Gap: Using Creativity And The Arts To Help Autistic Adolescents And Young Adults Build Skills For Employment, Eliana Rachel Grossman

Dissertations, Theses, and Capstone Projects

Neurodiversity-affirmative autism frameworks present a shift from deficit-based models of autism to the recognition that autism is but one of many facets of biodiversity that should be affirmed and embraced. However, there is little research examining links between creativity and autism that has adopted a neurodiversity-affirming approach. The dissertation aimed to expand upon the nascent interdisciplinary link between neurodiversity-affirmative autism research and creativity to 1) understand the creative experiences of autistic adolescents and young adults and 2) address the critical issue of chronic unemployment faced by autistic people.

The first study examined the perspectives of autistic adolescents and young adults …


Examining Visual Processing Of Hierarchical Figures Through Behavioral Measures And Pupillometry In Relation To Autistic Traits In Adults, Chloe Brittenham Jun 2024

Examining Visual Processing Of Hierarchical Figures Through Behavioral Measures And Pupillometry In Relation To Autistic Traits In Adults, Chloe Brittenham

Dissertations, Theses, and Capstone Projects

Autism spectrum disorder (ASD) and autistic traits in the general population are associated with differences in sensory processing, particularly within the visual domain. Previous studies examining global (i.e., overall gist) and local (i.e., detail) visual processing in relation to ASD have sometimes yielded contradictory findings yet converge on a common theme: slowed global processing and increased local bias associated with ASD. Despite this consensus, the mechanism underlying these differences remains unclear, whether it be differences in visual attention, higher or lower visual perception, and/or cognitive style. The use of traditional tasks and stimuli may further complicate the understanding of contributing …


In My Softest & Most Liberatory Dreams: Reflections On Holding Complexity & Decentering Whiteness, Richard C. Clark Jun 2024

In My Softest & Most Liberatory Dreams: Reflections On Holding Complexity & Decentering Whiteness, Richard C. Clark

Dissertations, Theses, and Capstone Projects

As the world contends with a global pandemic, climate catastrophes, white supremacy, coloniality, and concurrent genocides my attention splinters. In an act of futurity, or future making, I ask myself: What is needed to move from this place toward softer, more liberatory futures? This body of work finds its answer in exploring two interrelated concepts: Decentering Whiteness and Holding Complexity. Decentering Whiteness is the process of working toward a future where all the personal, spiritual, educational, epistemological, social, structural, psychological, financial, and systemic ties to white supremacy are unraveled. Holding Complexity weaves together knowledges of care, accountability, intersectionality, and …


The Cultural Complexity Of Immigrants And The Implications For Personality Assessment: Exploring The Role Of Frame Switching, Patrick Jay Lee Jun 2024

The Cultural Complexity Of Immigrants And The Implications For Personality Assessment: Exploring The Role Of Frame Switching, Patrick Jay Lee

Dissertations, Theses, and Capstone Projects

A significant body of personality research has focused on cross-national comparison, but less attention has been devoted to within-country subcultural complexity – especially with regards to the growing population of bicultural immigrants who subscribe to multiple cultural-value systems. Bicultural individuals have been found to view situations under distinct frames of reference corresponding to their heritage and host cultures, and their attitudes and behavior can vary depending on which frame is activated at a given moment. This dissertation investigates whether such frame switching effects can be caused by elements within a formal personality assessment setting, and in turn affect bicultural respondents’ …


Empirical Essays On Retail Investors, Institutional Investors, And Anomalies, Yuqing Yang Jun 2024

Empirical Essays On Retail Investors, Institutional Investors, And Anomalies, Yuqing Yang

Dissertations, Theses, and Capstone Projects

This dissertation consists of five chapters on market efficiencies through retail and international mutual fund investors.

Chapter 1 This chapter briefly introduces this dissertation.

Chapter 2 This chapter Anomalies Never Disappeared: The Case of Stubborn Retail Investors delves into the “stubborn” retail investors and finds that anomalies traded against by retail investors never disappear in the long run, defying the conventional wisdom that anomalies are disappearing in recent years as market efficiency improves. Incorporating retail trading, I develop asset pricing models that surpass existing prominent models in explaining these long-run alphas. I hypothesize that retail investors exacerbate anomalies: the more …


Chipping The Blue Wall: The Effect Of Dogs On Police Officer Receptivity To An Employee Assistance Program, Kenneth M. Quick Jun 2024

Chipping The Blue Wall: The Effect Of Dogs On Police Officer Receptivity To An Employee Assistance Program, Kenneth M. Quick

Dissertations, Theses, and Capstone Projects

There is substantial evidence that demonstrates the negative impact of stress on police officer mental health is increasing due in large part to perceived societal shifts in support for the police and trends in criminal justice reform efforts. While employee assistance programs (EAP) are the dominant mechanism for police agencies to address officer mental health, officers are reluctant to use them due to a combination of mental health stigma and organizational distrust. This dissertation studied police officer perceptions of an employee assistance program (EAP) and the effect of exposure to professionally trained dogs during an outreach session on indicators of …


Uncovering The Mimicry Of Online Review Breadth And Depth And Its Subsequent Effect On Consumer Responses, Andrea Pelaez Martinez Jun 2024

Uncovering The Mimicry Of Online Review Breadth And Depth And Its Subsequent Effect On Consumer Responses, Andrea Pelaez Martinez

Dissertations, Theses, and Capstone Projects

Word-of-mouth (WOM) in marketing occurs when consumers discuss a company's product or service or any consumption experience with their friends, family, and others with whom they have any relationship. With the advent of social media, this phenomenon has expanded rapidly into virtual environments where consumer conversation is enabled through chats, forums, social media posts, and online reviews. In response to this rapid growth of online WOM, academics and practitioners have focused their interest on this phenomenon and its implications on consumers, firms, and society. So far, the evidence of the critical role that online WOM plays in helping consumers make …


Me And Mathematics: “Doing What You’Re Talking About”: In Dialogue With My Family, Eden Morris Jun 2024

Me And Mathematics: “Doing What You’Re Talking About”: In Dialogue With My Family, Eden Morris

Dissertations, Theses, and Capstone Projects

This paper is a philosophically oriented accompaniment to my audio project (accessible through the following link: https://cuny.manifoldapp.org/projects/me-and-mathematics). Working together, the paper and audio collages form a call to action and a resource. My primary finding is the importance of doing what you’re talking about or exploring and implementing your ideas experientially. Doing what you’re talking about is important for effective teaching/learning and feeling in line with oneself. This working concept came to my attention during my research conversation with my oldest living relative, and then, again, with my youngest (non-baby) relative. This doing what you’re talking about is a way …


Cross-Linguistic Differences In Neural Encoding And Processing Of Stop Consonants: The Impact Of Language Experience On Attention Allocation, Aline Dos Santos Oliveira Jun 2024

Cross-Linguistic Differences In Neural Encoding And Processing Of Stop Consonants: The Impact Of Language Experience On Attention Allocation, Aline Dos Santos Oliveira

Dissertations, Theses, and Capstone Projects

This study aims to examine the intricate relationship between language experience and the neural processing of stop consonant speech sounds. Previous research has shown minimal differences in amplitudes and latencies of cortical Auditory Evoked Potentials (AEPs) to speech sounds across listeners from various language backgrounds. It is only towards the later latencies (around the P2 peak at 200 ms), that there have been suggestions of cross-linguistic differences. In addition, a recent study, observed an AEP difference between monolinguals and bilinguals when processing speech, specifically an "Nd effect”. The Nd effect, which is an increased negativity of the AEP is proposed …


Staying Power: The Struggle For Space And Place In Crown Heights, Brooklyn, Erin E. Lilli Feb 2024

Staying Power: The Struggle For Space And Place In Crown Heights, Brooklyn, Erin E. Lilli

Dissertations, Theses, and Capstone Projects

This dissertation looks at how gentrification touches down, at the neighborhood and individual scale, in Crown Heights and reproduces experiences of racial inequality in home and place. Taking an historical materialist approach and drawing on residential oral histories, this study frames these reproductions of racial inequality as always-in-tension with ongoing acts of resistance from Black homeowners, renters, and long-term residents. Specifically, the research explores the conditions under which Black residents of a predominantly Afro-Caribbean neighborhood acquire and maintain—and in some cases lose—their housing and sense of place and belonging. These residents resist the varied tactics of anti-Blackness such as landlord …


The Role Of Glutamate In The Medial Prefrontal Cortex In The Acquistion And Expression Of Conditioned Approach, Rudolf Nisanov Feb 2024

The Role Of Glutamate In The Medial Prefrontal Cortex In The Acquistion And Expression Of Conditioned Approach, Rudolf Nisanov

Dissertations, Theses, and Capstone Projects

A series of experiments were conducted to assess the role of glutamatergic stimulation in the dorsal and ventral regions of the medial prefrontal cortex (mPFC) in both the acquisition and expression of reward-related learning using a Pavlovian conditioning paradigm, the conditioned-approach paradigm. Rats with surgically implanted cannulas were exposed to Pavlovian conditioning sessions that occurred on three alternative days (acquisition) or seven consecutive days (expression). These 60-min conditioning sessions consisted of 30 pairings of light (CS) and food pellets (US) presented under a random time schedule. After a two-day break, rats underwent a session with no CS or US and …


A Candidate Needs Approach To Job Advertisements, Yuliya M. Cheban-Gore Feb 2024

A Candidate Needs Approach To Job Advertisements, Yuliya M. Cheban-Gore

Dissertations, Theses, and Capstone Projects

Organizations currently lack research-based best practice guidance on what information is most helpful for job seekers when deciding which jobs and organizations to apply to. This lack of guidance is a detriment because, typically, recruitment strategies are designed from the perspective of the organization’s needs –which is effective when the job market is organization, rather than candidate-driven. When the market is candidate-driven, it would benefit organizations to view the recruitment process through the lens of job seekers. The current studies focus on understanding one of the beginning stages of recruitment through the lens of job seekers: job advertisements. Through a …


An Examination Of Factors Associated With Ipv Victimization, Ipv Disclosure, And Help-Seeking Among Partnered Sexual Minority Men: An Integrated Theoretical Approach, Stephen Bosco Feb 2024

An Examination Of Factors Associated With Ipv Victimization, Ipv Disclosure, And Help-Seeking Among Partnered Sexual Minority Men: An Integrated Theoretical Approach, Stephen Bosco

Dissertations, Theses, and Capstone Projects

The emerging body of research illustrates that sexual minority cis men (SMM) in a relationship experience intimate partner violence (IPV) at rates comparable to those reported by cis women in a heterosexual relationship. Although research on IPV in male relationships has increased, it is a phenomenon that remains considerably understudied compared to research examining IPV in a heterosexual relationship. Despite comparable rates of IPV victimization, SMM are less likely to disclose and use informal and formal support services compared to heterosexual women. To conceptualize and understand challenges to disclosure and help-seeking as well as identify facets to develop relevant and …


A Pearl Ravaged: The Paradox Of Haiti And Its Socioeconomic Origins, Isabel Ishibe Exel Feb 2024

A Pearl Ravaged: The Paradox Of Haiti And Its Socioeconomic Origins, Isabel Ishibe Exel

Dissertations, Theses, and Capstone Projects

Saint-Domingue was once the most profitable colony of the Caribbean, the so-called pearl of the Antilles. Nowadays, Haiti is known for being the poorest country in the Western Hemisphere, a dramatic shift that raises the question of the factors contributing to Haiti's current state, marked by persistent violence, natural disasters, and political instability. Various discourses have framed Haiti as a country doomed for failure. However, relying on binary concepts such as success and failure is counterproductive to a refined analysis. How, then, should we structure this conversation? My ultimate goal for this work is to provide a nuanced analysis of …


The Divided Self: Internal Conflict In Literature, Philosophy, Psychology, And Neuroscience, Yulia Greyman Feb 2024

The Divided Self: Internal Conflict In Literature, Philosophy, Psychology, And Neuroscience, Yulia Greyman

Dissertations, Theses, and Capstone Projects

This thematic project examines the notion of self-division, particularly in terms of the conflict between cognition and metacognition, across the fields of philosophy, psychology, and, most recently, the cognitive and neurosciences. The project offers a historic overview of models of self-division, as well as analyses of the various problems presented in theoretical models to date. This work explores how self-division has been depicted in the literary works of Edgar Allan Poe, Don DeLillo, and Mary Shelley. It examines the ways in which artistic renderings alternately assimilate, resist, and/or critique dominant philosophical, psychological, and scientific discourses about the self and its …


From The Outside Looking In: Transmasculine Narrative Identity, Experiences, And Larger Narratives On Social Media, Micah Roldan Feb 2024

From The Outside Looking In: Transmasculine Narrative Identity, Experiences, And Larger Narratives On Social Media, Micah Roldan

Dissertations, Theses, and Capstone Projects

Narrative identity development is an essential process in how individuals perceive themselves and the world around them. Often, narrative identity is studied in cisgender heterosexual individuals and applied to others without the acknowledgment of individuals that fall outside of these categories. Drawing upon existing literature and autoethnography, this thesis aims to meaningfully bridge this gap by studying the narrative identity development of transmasculine individuals through the lens of social media. This thesis proposes that the use of social media to share gender transition journeys has created a new digital trans and queer narrative for users and viewers. This narrative is …


Seeing Safety In Red: Expressions Of Interpersonal Gratitude Affects Conservatives’ Political Attitudes In The United States, Kyle M. Anderson Feb 2024

Seeing Safety In Red: Expressions Of Interpersonal Gratitude Affects Conservatives’ Political Attitudes In The United States, Kyle M. Anderson

Dissertations, Theses, and Capstone Projects

The current research focuses on how the expression of interpersonal gratitude might affect conservative attitudes, behaviors, and policy support in the United States. This was investigated either through expressions of gratitude or receiving gratitude to an interpersonally close other, as in Studies 1 and 2, or expressing gratitude to an authority figure or equal in one’s life, as in Study 3. Study 1 showed that expressing gratitude, relative to receiving gratitude, reduced support for general conservative ideology. Using serial mediation analyses, Study 2 demonstrated that expressions of gratitude, relative to receiving gratitude, directly reduced perceptions of relational uncertainty, which increased …


In-Work Recovery Among Hybrid Employees: Examining The Relationships Between Stressors, Recovery Experiences, And Strains, Stefanie Larsen Feb 2024

In-Work Recovery Among Hybrid Employees: Examining The Relationships Between Stressors, Recovery Experiences, And Strains, Stefanie Larsen

Dissertations, Theses, and Capstone Projects

There has been a drastic increase in the number of hybrid employees (i.e., employees who work remotely for part of a workweek) since the COVID-19 pandemic. While previous research has highlighted some of the benefits and costs of remote work, research on hybrid work is still in its early stages. One area that remains unclear is how hybrid work relates to stressor experiences and in-work recovery from work. The present study examined how levels of specific stressors (i.e., workload, availability pressure) vary depending on whether employees work remotely or in the office, and how the variations of these stressors across …


Exploring Cross-Linguistic Speech Perception In Hindi, English, And Romance-Language Through Temporal Dynamics Of Neural Activity, Yuga Kothari Feb 2024

Exploring Cross-Linguistic Speech Perception In Hindi, English, And Romance-Language Through Temporal Dynamics Of Neural Activity, Yuga Kothari

Dissertations, Theses, and Capstone Projects

This study examines the effect of linguistic experience on the neural processing of Voice Onset Time (VOT) in Hindi and Romance language (Spanish and Portuguese) individuals who are bilingual in English and monolingual English speakers using the event-related potential (ERP) Mismatch Negativity (MMN) response. VOT is a linguistic property that measures the time elapsed between the release of a stop consonant and the beginning of voicing, that is, vocal fold vibration of a following vowel. In a double-oddball paradigm, participants’ (n = 41) ERP were recorded while listening to speech sounds differing in VOT. The bilabial short lag stop [p] …


Typologies Of Battering: Uncovering Patterns Of Coercive Tactics Used By Abusive Men In A Mixed Methods Study, Abbie L. Tuller Sep 2023

Typologies Of Battering: Uncovering Patterns Of Coercive Tactics Used By Abusive Men In A Mixed Methods Study, Abbie L. Tuller

Dissertations, Theses, and Capstone Projects

Coercive control provides a current day feminist understanding of intimate partner violence (IPV). Recent research has demonstrated the significance of coercive control and suggests it provides a more accurate understanding of IPV than using physical violence alone. Utilizing a feminist lens, this study’s first aim was to explore if typologies based on coercive control could be developed. The second and third aims were to explore if demographic differences and differences in masculinity exist across typologies. The final aim of this study was to continue the feminist understanding of IPV using the moral emotions of shame and guilt as an extension …


Parallel Processes Of Posttraumatic Stress And Metabolic Dysfunction: Long-Term Costs Of Trauma On The Psychological And Physical Health Of 9/11 Survivors, Shane W. Adams Sep 2023

Parallel Processes Of Posttraumatic Stress And Metabolic Dysfunction: Long-Term Costs Of Trauma On The Psychological And Physical Health Of 9/11 Survivors, Shane W. Adams

Dissertations, Theses, and Capstone Projects

Metabolic conditions (MetC) have been associated with posttraumatic stress disorder (PTSD) symptoms and may be critical indicators of the systemic physical sequelae of traumatic stress. Parallel process latent growth modeling wasapplied to longitudinal data collected from 35,788 9/11 survivors and used to model PTSD symptoms and MetC to determine how the development and course of one affect the other. A unidirectional relationship was found in which the intercept of PTSD symptoms predicted the slope of MetC. Hyperarousal (ß=.172) and emotional numbing (ß=.171) PTSD symptoms demonstrated the strongest association with the growth of MetC over and above …


Health Care Providers' Attributions Of Blame For Unintended Pregnancy And Hiv Acquisition Among Cisgender Women, Alison J. Goldberg Sep 2023

Health Care Providers' Attributions Of Blame For Unintended Pregnancy And Hiv Acquisition Among Cisgender Women, Alison J. Goldberg

Dissertations, Theses, and Capstone Projects

Unintended pregnancy and HIV are both possible but preventable outcomes of vaginal sex, and both can be prevented in similar ways (condoms, daily oral medication, etc.). Despite these similarities, providers more readily prescribe contraception to cisgender women, compared to PrEP (Guttmacher Institute, 2021; Raifman et al., 2019). Providers’ differential willingness to prescribe each medication cannot be attributed merely to differences in women’s need for pregnancy prevention vs. HIV prevention, as women account for nearly 20% of new HIV infections (CDC, 2021). Through three studies, I examined whether perceivers’ support for harm reduction (i.e., prescribing PrEP/contraception) and behavior reduction (i.e., discouraging …


How Smoking Became A Moral Issue: A Complex Systems Perspective On Moralization, Matthew Vanaman Sep 2023

How Smoking Became A Moral Issue: A Complex Systems Perspective On Moralization, Matthew Vanaman

Dissertations, Theses, and Capstone Projects

When something is morally wrong, it is in the moral domain; when something becomes morally wrong, it is moralized. But how do we know when something is in the moral domain, and how can we tell whether something is becoming moralized? The empirical study of morality, or a given person’s judgment of what constitutes moral virtue or vice, has historically approached these questions through one of three theoretical perspectives: cognitivism, which argues that people primarily or mostly use effortful thought to judge right from wrong; emotivism, which sees these judgments as flowing from emotion; and dual-process models, which …


Effects Of Genes And Gene-Environment Interactions On Work-Family Conflict And Enrichment, Peter Yu Sep 2023

Effects Of Genes And Gene-Environment Interactions On Work-Family Conflict And Enrichment, Peter Yu

Dissertations, Theses, and Capstone Projects

The COVID-19 pandemic has shown how macro-level issues can influence how we manage work and family responsibilities. Yet, work-family (WF) research at different levels of analysis is relatively scarce. To address this, I take a multilevel lens to study WF conflict and enrichment in the context of micro-level factors (in the form of genes), macro-level factors (in the form of family and community-level demands), and their cross-level interactions (i.e., gene–environment interactions). To study genetic main effects, I drew from the work-home resources model to identify four candidate genes associated with conditions that could impact the ability to accrue WF resources …


Wanting Under Surveillance: A Critical Analysis Of Young Women’S Sexual Desire, Jennifer Chmielewski Sep 2023

Wanting Under Surveillance: A Critical Analysis Of Young Women’S Sexual Desire, Jennifer Chmielewski

Dissertations, Theses, and Capstone Projects

The negotiation of sexual desire is argued to be a vital part of the development of women’s sense of agency and well-being. Whereas desire is a concept that is widely used, measured, and diagnosed, women’s experiences of desire are poorly understood. Heeding the calls of feminist psychologists for conceptual analysis, and the need to examine desire within the multiple intimate and sociopolitical contexts in which sexuality develops, my dissertation is a critical feminist analysis of young women’s desire, centered on their subjective and embodied experiences. Moving beyond questions of what women desire or how much desire they have, I explore …


Abuse Victimization And Impulsivity In Incarcerated Males: Examining The Roles Of Affective Instability And Trauma Symptoms, Jacqueline K. Douglas Sep 2023

Abuse Victimization And Impulsivity In Incarcerated Males: Examining The Roles Of Affective Instability And Trauma Symptoms, Jacqueline K. Douglas

Dissertations, Theses, and Capstone Projects

Incarcerated individuals with a history of physical and/or sexual abuse have been found to exhibit increased levels of impulsivity compared to those with no abuse history (Carli et al., 2014; Davis et al., 2017; Sergentanis et al., 2014). Given that impulsivity is a risk factor for criminal delinquency (Carroll et al., 2006; Kamaluddin et al., 2015; Zimmerman, 2010), it is important to gain a thorough understanding of psychological factors that may contribute to higher levels of impulsivity in incarcerated populations. The present study examined the mechanisms underlying the relationship of physical and/or sexual abuse history to impulsivity in a sample …


Examining The Prevalence And Psychopathological Correlates Of Paraphilic Interests In A Non-Clinical Sample, Dylan H. Abrams Sep 2023

Examining The Prevalence And Psychopathological Correlates Of Paraphilic Interests In A Non-Clinical Sample, Dylan H. Abrams

Dissertations, Theses, and Capstone Projects

The paraphilias are among the most contentious diagnoses in contemporary psychological discourse. One of the major debates is over the extent to which paraphilic interests and behaviors should be considered “deviant.” To address this issue, extant research has examined the prevalence of paraphilic interests and their correlation with psychopathology. Though findings suggest that certain paraphilic interests are relatively common, existing data may misrepresent true prevalence rates due to racially and ethnically homogenous sampling. Additionally, though an association between paraphilias and psychopathology has been found in forensic and clinical samples, this relation may not generalize to all individuals with paraphilic interests. …


Does The Apoe-Ε4 Allele Differentially Influence Cognition: A Longitudinal Investigation In Healthy Older Adults At Risk For Alzheimer’S Disease, Aditya Kulkarni Sep 2023

Does The Apoe-Ε4 Allele Differentially Influence Cognition: A Longitudinal Investigation In Healthy Older Adults At Risk For Alzheimer’S Disease, Aditya Kulkarni

Dissertations, Theses, and Capstone Projects

Background: The apolipoprotein E (APOE) ε4 allele is the strongest susceptibility factor for sporadic, late-onset, Alzheimer’s disease (AD). However, not all persons who carry the ε4 allele show significant cognitive decline, and thus do not progress to dementia. The impact of the ε4 allele on memory decline has been documented primarily in populations already demonstrating cognitive impairment (i.e., those with mild cognitive impairment or dementia), with fewer investigations completed in baseline healthy older adults. Investigations of the ε4 allele and its influence on non-memory domains are also sparse in the literature. Furthermore, these cognitive investigations are typically cross-sectional and …
