For The Love Of Teaching: Pre-Service Teachers’ Experience Of Moral Education, Anne Marie Foley Ruiz Aug 2023

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 …


Uncovering The Neural And Behavioral Factors That Underlie Changes In Processing Visual Orientation, Patrick Sadil Dec 2020

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 …


Shared Neural Substrates Of Perception And Memory: Testing The Assumptions And Predictions Of The Representational-Hierarchical Account, D. Merika W. Sanders Sep 2020

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 …


Relationships Between Personality Type And Cognitive Ability In Marmoset Monkeys (Callithrix Jacchus), Zachary Marciano Oct 2019

Relationships Between Personality Type And Cognitive Ability In Marmoset Monkeys (Callithrix Jacchus), Zachary Marciano

Masters Theses

Personality refers to multiple traits that are thought to be stable over time and across situations. It is recognized that personality has a neural basis and is associated with health outcomes. Whether personality is also associated with cognitive ability, however, is still a matter of intense debate. One way to examine these potential relationships is to use a nonhuman primate model for which complexities present in humans can be minimized. Recent research into the varying personality types of marmoset monkeys suggests that there are predominantly three to five core primary domains that most marmosets and other primates can be categorized …


Changes In Color Guidance Over The Course Of A Complex Visual Search, Ryan Papargiris Jul 2019

Changes In Color Guidance Over The Course Of A Complex Visual Search, Ryan Papargiris

Masters Theses

When searching for an object, we store a mental representation of the target, which guides our search through the use of attention. The effectiveness of this search guidance varies depending on the task and the relationship between target and distractors. With a better understanding of how search guidance changes over time within a trial, we can better compare the differences between experimental conditions. Eye tracking data from a variety of search tasks were analyzed to determine how color guidance varied over the course of the trial. Color guidance for a given fixation was evaluated based on the distance in color …


A Representational-Hierarchical Account: A New Theory Of False Memories, D. Merika Wilson Jul 2017

A Representational-Hierarchical Account: A New Theory Of False Memories, D. Merika Wilson

Masters Theses

Past research has supported a representational-hierarchical theory of memory and perception that extends the ventral visual stream into the medial temporal lobe. In this account, representations are organized in a hierarchical manner, such that structures located further anterior in the brain contain complex representations of whole objects and areas further posterior in the visual cortex contain representations of simple features. When conjunctive representations are compromised, an individual must rely on simple-feature representations to complete mnemonic and perceptual tasks. However, these simple-feature representations are susceptible to feature-level interference, which can cause false recognition of novel objects. The goal of the present …


The Role Of Social Class And Construal Level In Social Justice And Fairness Beliefs, Prerana Bharadwaj Jul 2017

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 …


The Influence Of Discrete Emotional States On Preferential Choice, Andrea M. Cataldo Jul 2016

The Influence Of Discrete Emotional States On Preferential Choice, Andrea M. Cataldo

Masters Theses

Past research has shown that emotion affects preferential choice outcomes. The goal of the present study was to further research on emotion and preferential choice by using mathematical modeling to investigate the effects of specific dimensions of emotion on the underlying mechanisms of preferential choice. Specifically, we aimed to determine whether the concurrent effects of positive-negative valence and situational certainty on attention and information accumulation threshold, respectively, would influence the magnitude of the similarity effect, a robust phenomenon in preferential choice. Participants first underwent either an Anger (negative and certain), Fear (negative and uncertain), or no (Control) emotion manipulation. All …


Audible Voice In Context, Airlie S. Rose Nov 2015

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 …


Linguistic Cognition And Bimodalism: A Study Of Motion And Location In The Confluence Of Spanish And Spain’S Sign Language, Francisco Meizoso Mar 2015

Linguistic Cognition And Bimodalism: A Study Of Motion And Location In The Confluence Of Spanish And Spain’S Sign Language, Francisco Meizoso

Doctoral Dissertations

The goal of this dissertation is to study the intrapersonal and symbolic function of gesture by a very specific type of population: hearing speakers of Spanish who, having been born to deaf parents, grew up developing a bimodal (Spanish and Spain’s Sign Language) linguistic interface, which borrows elements from the manual and spoken modalities. In the ordering of gestures devised by Kendon (1988) and cited by McNeill (1992), gesticulation and sign languages are placed at opposite ends of a continuum. At one end, gesticulation is formed by idiosyncratic spontaneous gestures lacking any conventional linguistic proprieties, which are produced in combination …


Attention Modulates Erp Indices Of The Precedence Effect, Benjamin H. Zobel Nov 2014

Attention Modulates Erp Indices Of The Precedence Effect, Benjamin H. Zobel

Masters Theses

When presented with two identical sounds from different locations separated by a short onset asynchrony, listeners report hearing a single source at the location of the lead sound, a phenomenon called the precedence effect (Wallach et al., 1949; Haas, 1951). When the onset asynchrony is above echo threshold, listeners report hearing the lead and lag sounds as separate sources with distinct locations. Event-related potential (ERP) studies have shown that perception of separate sound sources is accompanied by an object-related negativity (ORN) 100-250 ms after onset and a late posterior positivity (LP) 300-500 ms after onset (Sanders et al., 2008; Sanders …


Transposed Letter Effects In Prefixed Words: Implications For Morphological Decomposition, Kathleen M. Masserang Jan 2010

Transposed Letter Effects In Prefixed Words: Implications For Morphological Decomposition, Kathleen M. Masserang

Masters Theses 1911 - February 2014

The nature of morphological decomposition in visual word recognition remains unclear regarding morphemically complex words such as prefixed words. To investigate the decomposition process, the current study examined the extent to which effects involving transposed letters are modulated when the transposed letters cross a morpheme boundary. Previous studies using masked priming have demonstrated that transposed letter effects (i.e. superior priming when the prime contains transposed letters than when it contains replacement letters) disappear or markedly decrease when the transposition occurs across a morpheme boundary. The current experiments further investigated transposed letter effects in prefixed words using both parafoveal previews in …
