Assessment Of Deficits In Specific Cognitive Domains In Older Adults Living With Hiv., Andrea Reyes-Vega, Harideep Samanapally, Rishikesh Rijal, Stephen P. Furmanek, Christopher B. Shields, Brandon C. Dennis, Smita Ghare, Shirish Barve

Faculty Scholarship

A significant proportion of people living with HIV (PLWH) have cognitive impairment. Moreover, approximately 70% of PLWH in the United States will be ≥50 years old by 2030, raising concerns of a higher incidence of dementia as they age. Accordingly, there is a clinical need to monitor their cognitive status. The aim of this study was to delineate specific cognition areas impacted in OALWH with a clinical diagnosis of neurocognitive impairment. We used a comprehensive set of tests (paper and NIH Toolbox Cognition Battery), to assess different cognitive domains in a total of 25 OALWH ≥ 50 years. 64% were …

Exploring Students’ Epistemological Understanding Of Atomic Structure Models, Claire V. Ward, Morgan Balabanoff

The Cardinal Edge

Developing a robust understanding of atomic structure and the nature of matter is foundational across chemistry and STEM courses. The development of this concept is challenging because it relies on models to illustrate something not directly observable. Scientific models are important tools used to explain phenomena, particularly phenomena that are not directly observable. In general chemistry, students are typically asked to consider four different models: (1) the particle model, (2) the nuclear model, (3) the Bohr model, and (4) the Quantum model. Each depiction has its own advantages and limitations, where instructors introduce each model to explain specific parts of …

White Men In White Coats: Children’S Attributions Of Scientific Knowledge Based On Race And Gender, Lillian C. Holm, Mariel R. Cox, Khushboo S. Patel, Judith H. Danovitch

The Cardinal Edge

Children use others’ characteristics (e.g., intelligence and niceness) to evaluate how much a person knows (Landrum et al., 2016). However, little is known about how gender and race influence children's perception of adults' scientific knowledge. The current study examined how children ages 5-8 (N = 25; 11 girls, 14 boys) perceive adults’ scientific knowledge. In the first task, children saw 8 different adults of varying race and gender (White man, White woman, Black man, Black woman) and rated their knowledge using a five-point scale. Children then chose one person out of two adults who they thought knew more about a …

The Science Of Learning: Understanding The Learning Process And Its Implementation Into The Classroom, Robert Hawkins

The Cardinal Edge

College and higher education is often seen as the next step for many students pursuing a particular career or field. These institutions strive to facilitate learning and maintain a rewarding academic environment. However, students often face various challenges when first attending college which is reflected by high levels of dropout and withdrawal from general education courses, especially for first-time students. In fact, according to the education data initiation, “at 4-year institutions, 18.4% of first-time, full-time college freshmen dropped out between 2019 and 2020” (Hansen & Checked, 2022). One of these challenges is understanding the process of learning on a fundamental …

Adjusting For Speaking Rate When Perceiving Speech In Background Noise., Dawson C Stephens

College of Arts & Sciences Senior Honors Theses

Speech perception is a very relevant concept occurring every day. Acoustic context effects such as temporal contrast effects (TCEs) influence perception significantly. For instance, when a faster context sentence is spoken, the participant should perceive the following target word as slower and more like /t/ in “tier”; when a slower context sentence is spoken, the participant should perceive the following target sound as faster and more like /d/ in “deer”. Recent work by Bosker et al. (2020) concluded that selective attention (directing attention to a specific stimulus while ignoring surrounding stimuli) had no effect on TCEs, suggesting they were automatic …

The Effect Of Object Contact On Pre-Reaching Infants' Causal Perception., Mallory L. Thompson

College of Arts & Sciences Senior Honors Theses

The Sticky Mittens (SM) paradigm is an object manipulation task that provides infants the opportunity to explore objects through active experience before they have the necessary motor skills to do so on their own. Positive cognitive outcomes like increased attention to objects, object engagement, object exploration, and causal perception have been shown to result from active SM experience (Libertus & Needham, 2010; Rakison & Krogh, 2012). Researchers are interested in understanding which aspects of SM training are important for infant learning. Although there have been many SM studies looking at different variables, such as active vs. passive experience and parent …

The Motion Aftereffect: Mechanisms And Variants, Erica E. Hassoun

The Cardinal Edge

The motion aftereffect causes a visual stimulus to undergo apparent motion. An adapting stimulus, which moves in a specific direction, adapts motion-responsive neurons in the middle temporal area (V5) to that direction of motion. Viewing a second stimulus, a test stimulus, produces apparent motion in the direction opposite that of the initial stimulus. Neural networks involved in attention and working memory are also implicated in the motion aftereffect. There is still little known regarding the mechanisms of the motion aftereffect, despite extensive documentation in the literature. This review discusses established knowledge of the motion aftereffect, focusing primarily on the middle …

The Effect Of Parent Interactions On Young Infants’ Visual Attention In An Object Manipulation Task., Nonah Marie Olesen

Electronic Theses and Dissertations

The Sticky Mittens (SM) task, an object-manipulation task that facilitates typically developing pre-reaching infants’ learning through active experience with objects, is often utilized to understand how experience affects young infants’ learning about objects. SM experience has been shown to increase infants’ attention to objects, object engagement, and object exploration (Libertus & Needham, 2010; Needham, Barrett, & Peterman, 2002) and facilitates development of causal perception (Rakison & Krogh, 2012; Holt, 2016). Although the majority of SM studies have involved parents interacting naturally with their infants, few have focused on how those interactions affect infants’ learning and performance during or after SM. …

The Effect Of Parent Interaction On Pre-Reaching Infants’ Visual Attention During An Object Manipulation Task., Jalena N. Slaton

College of Arts & Sciences Senior Honors Theses

Infants do not begin intentionally reaching for and grasping objects until around 5 months of age. The sticky mittens paradigm (SM) provides infants the opportunity to manipulate and explore objects on their own. Active SM experience has been shown to lead to positive cognitive outcomes (Libertus & Needham, 2010), including facilitating causal perception (Rakison & Krogh, 2012). While some aspects of SM that contribute to positive outcomes are well understood (e.g., active vs. passive experience), the role of parent interactions has received little attention. In this study, SM training was used to investigate the role that parents play in their …

The Role Of Talker In Adjusting For Different Speaking Rates In Speech Perception, Chloe M Sharpe, Christian Stilp

Undergraduate Arts and Research Showcase

Speech perception is heavily influenced by acoustic context effects, where perception of a sound is influenced by acoustic properties of surrounding sounds. Talker variability, or the acoustic variability among different talkers, can disrupt these context effects. Studies have shown that talker variability does impact Spectral Contrast Effects (SCEs; an acoustic context effect induced by variations in frequency), but it is unknown if Temporal Contrast Effects (TCEs; an acoustic context effect induced by speech rate) are similarly affected. To test this, on each trial, listeners heard a context sentence (spoken at a fast or slow rate) followed by the target word …

Words Have A Weight: Language As A Source Of Inner Grounding And Flexibility In Abstract Concepts, Guy Dove, Laura Barca, Luca Tummolini, Anna M. Borghi

Faculty Scholarship

The role played by language in our cognitive lives is a topic at the centre of contemporary debates in cognitive (neuro)science. In this paper we illustrate and compare two theories that offer embodied explanations of this role: the WAT (Words As social Tools) and the LENS (Language is an Embodied Neuroenhancement and Scaffold) theories. WAT and LENS differ from other current proposals because they connect the impact of the neurologically realized language system on our cognition to the ways in which language shapes our interaction with the physical and social environment. Examining these theories together, their tenets and supporting evidence, …

The Effects Of Monaural And Binaural Cues On Perceived Reverberation By Normal Hearing And Hearing-Impaired Listeners., Gregory Matthew Ellis

Electronic Theses and Dissertations

This dissertation is a quantitative and qualitative examination of how young normal hearing and young hearing-impaired listeners perceive reverberation. A primary complaint among hearing-impaired listeners is difficulty understanding speech in noisy or reverberant environments. This work was motivated by a desire to better understand reverberation perception and processing so that this knowledge might be used to improve outcomes for hearing-impaired listeners in these environments. This dissertation is written in six chapters. Chapter One is an introduction to the field and a review of the relevant literature. Chapter Two describes a motivating experiment from laboratory work completed before the dissertation. This …

Illusory Correlation And Perceived Criminality., Rachel A. Carter

College of Arts & Sciences Senior Honors Theses

Illusory correlation is the false perception that a relationship exists between two variables. Previous studies have shown that people sometimes perceive a relationship between minority-group members and negative characteristics, when in fact, there is no informational basis for this perception. The current study investigates whether people readily perceive a relationship between criminality and minority groups, as is sometimes seen in society. Participants learned about the behaviors of members of two groups, arbitrarily labeled S and T. The ratio of positive:negative behaviors was the same for both groups (2:1). However, participants were shown fewer statements about Group T, making it a …

Assessing The Relationship Between Talker Normalization And Spectral Contrast Effects In Speech Perception., Ashley Atri Assgari

Electronic Theses and Dissertations

Speech perception is influenced by context. This influence can help to alleviate issues that arise from the extreme acoustic variability of speech. Two examples of contextual influences are talker normalization and spectral contrast effects (SCEs). Talker normalization occurs when listeners hear different talkers causing speech perception to be slower and less accurate. SCEs occur when spectral characteristics change from context sentences to target vowels and speech perception is biased by that change. It has been demonstrated that SCEs are restrained when contexts are spoken by different talkers (Assgari & Stilp, 2015). However, what about hearing different talkers restrains these effects …

"Triggers": Systematic And Social Cues For Black College Student Racial Self-Consciousness And Rejection Sensitivity, Race-Based., Leanna T. Luney

Electronic Theses and Dissertations

Scholars have examined black student well-being in varying ways including through the framing of race-based rejection sensitivity (Downey & Feldman, 1996; Mendoza-Denton, Downey, Purdie, Davis, & Pietrzak, 2002) and racial self-consciousness (Clark & Clark, 1939). Research shows that black students perform worse academically when they display high levels of race-based rejection sensitivity and racial self-conscious levels (Brannon & Taylor, 2015; Clark & Clark, 1939; Koehler & Skvoretz, 2010), and feelings of racial self-consciousness or rejection sensitivity stem from discriminatory and prejudicial experiences. However, research has not fully connected the broader context surrounding black students in college to their high levels …

Mechanisms Responsible For The Development Of Causal Perception In Infancy., Nicholas A. Holt

Electronic Theses and Dissertations

The aim of the current dissertation was to investigate the mechanisms that contribute to the emergence of causal perception in infancy. Previous research suggests that the experience of self-produced causal action may be necessary to promote the development of causal perception (Rakison & Krogh, 2012). The goal of the current study was two-fold: (1) to further explore the roles of self-produced action, haptic, proprioceptive and visual information, and parental interaction on young infants’ understanding of causality. To assess the impact of these factors on infants’ causal learning, 4½-month-olds were randomly assigned to one four conditions. Three of the conditions (Active …

How To Go Beyond The Body: An Introduction, Guy Dove

Faculty Scholarship

Embodied cognition represents one of most important theoretical developments in contemporary cognitive science. Many cognitive processes appear to be influenced by body morphology, emotions, and sensorimotor systems. This perspective is supported by an ever increasing collection of empirical studies that fall into two broad classes: one consisting of experiments that implicate action, emotion, and perception systems in seemingly abstract cognitive tasks and the other consisting of experiments that demonstrate the contribution of bodily interaction with the external environment to the performance of such tasks.

Now that embodied cognition is fairly well established, the time seems right for assessing its further …

The Effects Of Perceived Enjoyable Activities On Cognition In Late-Life., Hannah D. Gardner

College of Arts & Sciences Senior Honors Theses

Previous research suggests that more involvement in various activities can help delay cognitive decline in older adults. Few studies have examined both the impact of frequency and perceived enjoyment of different types of activities on cognition. This study analyzed the relationship between frequency and pleasure of activities and cognition by running correlations using the five different subscales of the California Older Person’s Pleasant Events Schedule (COPPES) and a battery of cognitive tests (Block Design, Animal Naming, Boston Naming Test, Trails A, Trails B, CVLT-LDFR, & Digit Span). It was hypothesized that higher frequency as well as higher level of enjoyment …

A Mindfulness-Based Intervention To Reduce Stress In Undergraduates., Dirk Anthony Dorsel

College of Arts & Sciences Senior Honors Theses

This study piloted a mindfulness-based intervention to reduce stress in university undergraduates, and explore effects on psychological and biological indicators of stress. Mindfulness is “the awareness that emerges through paying attention on purpose, in the present moment and non-judgmentally to the unfolding of experience moment-by-moment” (Kabat-Zinn, 1994). The one week mindfulness intervention used audiobased mindfulness tracks recorded by Clinical Psychologist Paul Salmon. These tracks taught the basics of mindfulness. Participants were asked to listen to the tracks for 30 minutes a day for five days of the intervention. Perceived stress, self-reported anxiety, self-reported depression, heart rate and skin conductance were …

On The Need For Embodied And Dis-Embodied Cognition, Guy Dove

Faculty Scholarship

This essay proposes and defends a pluralistic theory of conceptual embodiment. Our concepts are represented in at least two ways: (i) through sensorimotor simulations of our interactions with objects and events and (ii) through sensorimotor simulations of natural language processing. Linguistic representations are “dis-embodied” in the sense that they are dynamic and multimodal but, in contrast to other forms of embodied cognition, do not inherit semantic content from this embodiment. The capacity to store information in the associations and inferential relationships among linguistic representations extends our cognitive reach and provides an explanation of our ability to abstract and generalize. This …
