For The Love Of Teaching: Pre-Service Teachers’ Experience Of Moral Education, Anne Marie Foley Ruiz

Doctoral Dissertations

Moral aspects of teaching arise each and every day, yet we lack information about how prepared teachers feel about this critical aspect of teaching. This multi-case study explores perceptions of five pre-service teachers in an elementary teacher education program in Western Massachusetts. A series of interviews explore their histories prior to the program and their experiences in the program as related to the pre-service teachers’ orientations to the moral work of teaching. Research questions address the awareness and self-efficacy of student teachers in implementing the moral aspects of teaching. Using Thematic Analysis (Braun & Clark, 2006), this study explores beliefs …

Investigating The Transfer Of Learning, Psychological, And Neural Effects In Immersive Virtual Reality, Logan Taylor Markwell

Doctoral Dissertations

Achieving mastery or expertise requires a substantial amount of quality practice. Recent technological developments have introduced a novel approach to practice, virtual reality. Specifically, virtual reality offers a low-cost, customizable opportunity to practice while minimizing the risk of the individual. Given that some types of practice may not lead to the acquisition of a motor skill, or worse, lead to detriments of that skill, understanding the developing science of motor behavior in relation to virtual reality is imperative. The following literature review will begin with a brief historical account of the evolution of virtual reality. Next, some terms of virtual …

Visual Working Memory Encoding And Action: An Investigation Using Fnirs And Mouse-Tracking, Kaleb Thomas Kinder

Doctoral Dissertations

Visual working memory (VWM) guides the motor system by temporarily keeping relevant information in mind. As an interface between perception and action, VWM plays a critical role in supporting goal-directed behavior. Research on the relationship between VWM and action has primarily focused on the effect of VWM on motor output. Traditional approaches index outcome responses, such as accuracy, but this practice provides limited information on underlying VWM processes. Conversely, the influence of action on VWM processes has received less attention and its neural correlates are not well understood. In this thesis, I examined VWM-action links using functional near-infrared spectroscopy (fNIRS) …

Assessing Potential Cognitive Precursors To Math Anxiety: Non-Symbolic Operations And Symbolic Ordinality In Adults, Eli Zaleznik

Doctoral Dissertations

Math anxiety, or a sense of dread related to performing mathematics, affects a wide population of students and adults, but we do not fully understand how math anxiety comes into being. One possibility is the Reduced Capacities Theory, which suggests that natural variations in numeric/spatial capacities are a causal factor in math anxiety. To understand how these numeric capacities relate to math anxiety in adults, this work focuses on three areas that remain underexplored. Chapter 2 focuses on performing operations on nonsymbolic quantities, which has not yet been tested in relation to math anxiety. We tested the hypothesis that performing …

What Did You Expect? An Investigation Of Lexical Preactivation In Sentence Processing, Jon Burnsky

Doctoral Dissertations

Language users predictively preactivate lexical units that appear to the comprehen- der to be likely to surface. Despite ample language experience and grammatical competence, it appears that language users tend to preactivate verbs in some contexts, called role-reversal contexts, that would create plausibility violations if they were to actually appear; these verbs assign thematic roles to their arguments in such a way that it leads to implausibility. These anomalous predictions provide a window into the mechanisms underlying lexical preactivation and are the case study that this dissertation focuses in on. This dissertation is an exploration of what linguistic information is …

Representation Of Reward And Risk In The Brain’S Motor System: Studies In Adolescents And Adults, Xingjie Chen

Doctoral Dissertations

In the neuroscience of economic decision making, the brain’s motor system has been ascribed a role in implementing choice actions. However, recent work has revealed canonical motor signals much in advance of choice action, possibly indicating their role in evaluation of decision options. In the current dissertation, we applied multimodal neuroimaging combining EEG and fMRI and used a novel paradigm that temporally separated the evaluation phase from the action phase of a decision-making process to investigate the mechanisms through which the motor control system contributes to decision making. Additionally, we further examined the developmental changes during the two phases of …

Mental Fatigue: Examining Cognitive Performance And Driving Behavior In Young Adults, Abigail F. Helm

Doctoral Dissertations

Mental fatigue causes an increase in task-based EEG theta and alpha power and a decrease in performance (for a review, see Tran et al., 2020). However, little is known about the emergence of mental fatigue in resting state EEG recordings and whether the progression of mental fatigue over time is influenced by individual differences. The current dissertation examined the utility of resting state EEG as a measure of mental fatigue by testing whether EEG power changed in young adults over the course of a cognitively demanding battery of tasks. The current dissertation also tested how this measure of mental fatigue …

Experience With Difficult Target Discrimination Makes Search Less Efficient: An Analysis Using Eye Movements, Junha Chang

Doctoral Dissertations

Recent studies demonstrate that experience influences observers’ strategic attentional guidance in visual searches. The current study explored how experience with difficult target color discrimination influences search strategy. Two participant groups were compared through seven dual-target search experiments: A hard search experience group and an easy search experience group. The easy search experience group performed only the easy color discrimination trials in which the two targets were easily distinguishable from distractors in the color dimension. The hard search experience group performed the same easy discrimination trials in half of the trials. The other half were difficult color discrimination trials in which …

Investigating The Self-Efficacy Awareness Of Black Female Technology Leaders, Marie Roberts De La Parra

Doctoral Dissertations

Black female technology leaders lack leadership opportunities, which affects their self-efficacy and is a crucial concern. Self-efficacy is based on the concept that an individual’s belief in what they can achieve influences their actions and how much effort they invest in the selected action. Self-persuasion can provide high or low self-satisfaction as a determinant for creating incentives for success or failure and converting thoughts and emotions to actions. Limited research has investigated the mindset, the thought patterns, and the self-belief undertaken by Black females in the world of technology. Despite limited amounts of research, data suggest that Black female leaders …

Person-Based Prominence In Ojibwe, Christopher Hammerly

Doctoral Dissertations

This dissertation develops a formal and psycholinguistic theory of person-based prominence effects, the finding that certain categories of person such as "first" and "second" (the "local" persons) are privileged by the grammar. The thesis takes on three questions: (i) What are the possible categories related to person? (ii) What are the possible prominence relationships between these categories? And (iii) how is prominence information used to parse and interpret linguistic input in real time? The empirical through-line is understanding obviation — a “spotlighting” system, found most prominently in the Algonquian family of languages, that splits the (ani- mate) third persons into …

Uncovering The Neural And Behavioral Factors That Underlie Changes In Processing Visual Orientation, Patrick Sadil

Doctoral Dissertations

From moment to moment, the visual environment appears stable; despite prolonged scrutiny, the edge of a desk is not perceived to change. But this apparent stability emerges from perceptual and decisional systems that undergo continuous modulation. In two chapters, I focus on two different kinds of modulation to the processing of visual orientation (i.e., the tilt of an edge). In both chapters, the form of modulation is latent, obscured by standard analyses. To detect those latent changes in perceptual decisions, I develop in this dissertation new statistical tools, at both behavioral and neural levels. In the first chapter, I consider …

Neural Correlates Of Individuation And Subordinate-Level Categorization Of Other-Race Faces In Infancy, Kelly Roth

Doctoral Dissertations

Perceptual narrowing is a domain-general process in which infants move from a broad sensitivity to a wide range of stimuli to developing expertise within often experienced native stimuli (Maurer & Werker, 2014). One outcome of this is the own-race bias, characterized by an increasing difficulty in discriminating other-race faces with age and experience for those raised in a racially homogenous environment (Anzures, Quinn, Pascalis, Slater, Tanaka, & Lee, 2013). Recent theorists have proposed that this is due to a categorization-individuation process, wherein infants begin to categorize non-native stimuli, such as other-species’ faces, but individuate native stimuli, such as often-experienced human …

Shared Neural Substrates Of Perception And Memory: Testing The Assumptions And Predictions Of The Representational-Hierarchical Account, D. Merika W. Sanders

Doctoral Dissertations

Proponents of the representational-hierarchical (R-H) account claim that memory and perception rely on shared neural representations. In the ventral visual stream, posterior brain areas are assumed to represent simple information (e.g. low-level image properties), but the complexity of representations increases toward more anterior areas, such as inferior temporal cortex (e.g., object-parts, objects), extending into the medial temporal lobe (MTL; e.g. scenes). This view predicts that brain structures along this continuum serve both memory and perception; a structure’s engagement is determined by the representational demands of a task, rather than the cognitive process putatively involved. In a neuroimaging study, I searched …

Testing The Convergent Retrieval Learning Theory Of Testing Effects, William J. Hopper

Doctoral Dissertations

What is learned from retrieving a memory that is not learned by studying the same information? In response to this question, I have proposed a new theory of retrieval-based learning in which I argue that retrieval strengthens the ability to completely activate all portions of a memory trace from an initial state of partial activation. In effect, retrieval serves to unitize the features of a memory, making the entire memory remain retrievable in the future when cue-related activation may be weaker. This theory, called the Primary and Convergent Retrieval (PCR) model, explains why practice tests produce both better long-term retention …

A Flexible Comparison Process As A Critical Mechanism For Context Effects, Andrea M. Cataldo

Doctoral Dissertations

Context effects such as the attraction, compromise, and similarity effects demonstrate that a comparison process, i.e., a method of comparing dimension values, plays an important role in choice behavior. Recent research suggests that this same comparison process, made more flexible by allowing for a variety of comparisons, may provide an elegant account of observed correlations between context effects by differentially highlighting dimension-level and alternative-level stimulus characteristics. Thus, the present experiments test the comparison process as a critical mechanism underlying context-dependent choice behavior. Experiment 1 provides evidence that increasing a dimension-level property, spread, promotes the attraction and compromise effects and reduces …

Computing Agreement In A Mixed System, Sakshi Bhatia

Doctoral Dissertations

This dissertation develops a comprehensive response to the question of how agreement is computed in Hindi-Urdu – a language with a mixed agreement system where the verb can agree with a subject or an object depending on the structural context. This dissertation covers new empirical and theoretical ground in two domains. First, I identify three kinds of atypical agreement patterns which are not accounted for under traditional approaches Hindi-Urdu agreement -- verb agreement with the nominal component of Noun-Verb complex predicates, long distance agreement of embedding Adjective-Verb predicates with embedded infinitive clause objects, and copular agreement in identity copula structures. …

Hearing And Seeing A Speaker: How Perceptual And Cognitive Factors Modulate The Dynamics Of Audiovisual Speech Perception, Elina Kaplan

Doctoral Dissertations

In face-to-face conversations, listeners process and combine speech information obtained from hearing and seeing the speaker talk. Audiovisual speech typically leads to more robust recognition of speech, as it provides more information for recognition but also as it helps listeners adjust to speaker idiosyncrasies. The goal of the current thesis was to examine how certain perceptual and cognitive factors modulate how listeners use visual speech to facilitate momentary speech perception and to adjust to a speaker’s idiosyncrasies. Results showed that (older) listeners’ sensitivity to cross-modal synchrony is related to the size of the audiovisual interactions during early perceptual processing. Furthermore, …

The Effect Of Familiarity On Learning With Video Clips Containing Seductive Details, Jonah Lee Ruddy

Doctoral Dissertations

Seductive information included in educational lessons can arouse students’ emotional and situational interest. However, research on seductive details across instructional modalities shows both helpful and harmful effects on learning. The seductive details effect describes the negative influence of interesting, but irrelevant, information on achieving learning goals. Results from studies of videos with relevant and seductive details in multimedia lessons are inconclusive. Prior knowledge of target information has been shown to moderate the seductive details effect. In this study, the moderating effect of prior exposure to, or familiarity with, seductive, rather than target, information was explored using a multifactorial design. The …

Executive Functioning Abilities And Social Competence In Undergraduates, Megan Carl

Doctoral Dissertations

Despite separate literatures linking attention-deficit/hyperactivity disorder (ADHD) symptoms and executive functions to social competence, no study has examined the simultaneous relationship of these two processes in adults. Beauchamp and Anderson (2010) propose the Socio-Cognitive Integration of Abilities (SOCIAL) model a biopsychosocial model as an explanation for the development of social competence. Given the patterns of social and neurological development in ADHD, it may be consistent with the SOCIAL model. Subcomponents of Beauchamp and Anderson’s (2010) SOCIAL model were utilized to examine the extent to which attention-deficit/hyperactivity disorder (ADHD) symptom severity moderated the relationship between executive function (EF) and social competence …

The Role Of Social Class And Construal Level In Social Justice And Fairness Beliefs, Prerana Bharadwaj

Doctoral Dissertations

What predicts support for the redistribution of resources to improve socioeconomic inequality? Social class, or the subjective perception of one’s resources and position in relation to others in a larger society, was examined as one relevant characteristic. Across four experiments, social class as subjective social status was manipulated (two) and measured (all four), and found to have a significant negative effect on support for the moral values of group-based equality (social justice) but not on individual deservingness (fairness) separate from political identity and other demographic characteristics. This effect was seen on stated principles but particularly relevant in approval ratings of …

Not Just Noise: Individual Differences In Cognitive Ability And Response Bias, Tina Chen

Doctoral Dissertations

Response bias is a component of decision making that can be defined as the general willingness to respond a certain way. For example, in recognition memory, one can have a response bias towards responding that a test item has been previously studied, or in reasoning, one can have a response bias towards responding that a conclusion is logically valid. However, not all individuals have the same response bias. Indeed, there is some evidence that response bias is a stable cognitive trait in memory that differs across individuals (Kantner & Lindsay, 2012, 2014). One predictor of this trait may be cognitive …

The Effect Of Interruptions On Primary Task Performance In Safety-Critical Environments, Cheryl Ann Nicholas

Doctoral Dissertations

Safety critical systems in medicine utilize alarms to signal potentially life threatening situations to professionals and patients. In particular, in the medical field multiple alarms from equipment are activated daily and often simultaneously. There are a number of alarms which require caregivers to take breaks in complex, primary tasks to attend to the interruption task which is signaled by the alarm. The motivation for this research is the knowledge that, in general, interrupting tasks can have a potentially negative impact on performance and outcomes of the primary task. The focus of this research is on the effect of an interrupting …

The On-Screen Water Cooler: Effects Of Televised User-Generated Comments On Cognitive Processing, Social Presence, And Viewing Experience., Jaclyn Ann Cameron

Doctoral Dissertations

Social television combines traditional television viewing and interactions with social media to create a phenomenon that connects otherwise autonomous viewers through a shared viewing experience. This dissertation explores one type of social television: on-screen user-generated comments. Although the practice spans multiple television genres, little is known about its effect on viewers’ cognitive processing of the media, perceptions of the social presence of other viewers, or the viewers’ experience of the media. Two experimental studies explored the effects of on-screen user-generated comments on cognitive processing of the media message, the effect of manipulating the content of on-screen user-generated comments and individual …

Chronotype Preference, Partial Sleep Deprivation, And Executive Functions Performance Throughout The Wake-Cycle, Devin Layne Merritt

Doctoral Dissertations

Sleep is vital to survival and well-being. Adequate sleep, which is conceptualized in terms of quantity and quality, is positively related to a number of cognitive functions. In terms of length, it has been recommended that individuals in late adolescence and adulthood should receive no less than eight hours of sleep. Negative effects on higher-order mental processes have been found in states of sleep deprivation. Individuals who experience total sleep deprivation show decrements in performance on tasks of executive function (i.e. sustained attention, planning, and decision making). However, the effects of partial sleep deprivation on executive functions has not been …

Influences On Self-Regulated Learning In Low-Income Children: Examining The Role Of Private And Social Speech As Self-Regulation Tools, Lisa Ann Connor

Doctoral Dissertations

Self-regulated learning (SRL) allows children to become autonomous learners through facilitating their active planning, monitoring, and evaluation of their performance in the classroom. Low-income children have been found to exhibit lower SRL abilities compared to middle-class children. SRL is linked to a number of long-term academic outcomes, and thus, understanding what contributes to this ability is essential for intervention. One potential mediator of children’s emerging SRL abilities is language. Social Constructivist Theory provides a lens to view this relationship between language and SRL, denoting the importance of both the physical and social dimensions of the classroom when examining cognitive development. …

Effect Of Mindfulness Training On Interpretation Exam Performance In Graduate Students In Interpreting, Julie E. Johnson

Doctoral Dissertations

Many graduate interpreting students struggle because the real-time, interactive nature of interpreting dictates that they be able to regulate their attention across different parallel cognitive activities and manage the inherent stress and unpredictability of the task. Within the framework of Cognitive Load Theory, this mixed-methods study explored the effect of short-term mindfulness training on consecutive interpreting exam performance using a quasi-experimental repeated-measures design. It also examined the relationships among mindfulness, stress, aspects of attention, and interpreting exam performance. The sample included 67 students (age M = 26.9 years; 82% female) across seven language programs (Chinese, French, German, Japanese, Korean, Russian, …

The Effect Of More And Less Relevant Details And Teacher Voice On Student Retention And Problem-Solving Transfer In Teacher-Created Multimedia, Colette Roche

Doctoral Dissertations

Many teachers create multimedia resources for their students, but most are uncertain as to what factors to consider regarding the design of multimedia instructional materials. Prior research identified instructional design principles for multimedia including the coherence principle and voice principle.

The purpose of this study was to test the coherence principle in a realistic setting using a heterogeneous group of ninth grade students in a humanities course to determine the effect of seductive details on retention and problem-solving transfer. To extend understanding of the voice principle, this study examined the effect of the teacher’s voice on student learning as measured …

Audible Voice In Context, Airlie S. Rose

Doctoral Dissertations

The term audible voice refers to the sound of the text experienced by the reader during silent reading. It was coined by Elbow in his Landmark Essays to help the field of composition wrestle more productively with the concept of voice in writing. In this dissertation, voice is not a metaphor. Drawing on contemporary work in psycholinguistics, cognitive psychology, and consciousness studies, it examines the phenomenon of audible voice as a form of inner speech[1]. The premise of this study is that the experience of audible voice by the reader is a unique intersection of the individual's inner landscape …

Estrogen-Sensitive Learning Is Not Affected By Combination Ethinyl Estradiol And Levonorgestrel Oral Contraceptive Use, Darlene F. Ficco

Doctoral Dissertations

Two studies were conducted to explore the cognitive effects of combination ethinyl estradiol and levonorgestrel contraceptive use during late adolescence and young adulthood. Three groups of females, naturally cycling, active pill phase, and hormone-free interval phase, were tested on a battery of estrogen-sensitive, i.e., place learning and word generation, and estrogen-insensitive, i.e., map drawing, mental rotation, digit span, story recall, and object recall, tasks. Study 2 was conducted as a means to replicate the findings observed in Study 1 and to manipulate task difficulty and sensitivity. Two measures of mood were administered, and salivary estradiol levels at time of testing …

The Relationship Between Demands And Resources And Teacher Burnout: A Fifteen-Year Meta-Analysis, Tammy Marie Stewart

Doctoral Dissertations

This meta-analysis explored the phenomenon of teacher burnout— the biggest contributor to teacher attrition (Owens, 2013; Unterbrink, 2014; Yu, 2015). The focus of this study was to use meta-analytical procedures to explore the relationship between burnout dimensions (i.e., emotional exhaustion, depersonalization, and feelings of personal accomplishment) and specific demand and resource correlates. Demand correlates included work overload, role conflict, role ambiguity, and student misbehavior. Resource correlates included peer support, supervisory support, and decision-making. This meta-analytical research method encompassed fifteen years of published and unpublished studies from January 2000 through January 2015. A total of 116 studies met the following inclusion …
