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 …

In-Between Spaces: Atmospheres, Movement And New Narratives For The City, Paul Alexander Stoicheff

Masters Theses

We often think of architecture as distinct buildings, yet as we move through the city we continuously pass through a built environment that is a collage of buildings. These spaces between buildings are underestimated as influences on our experience of everyday life in the city. Considering architecture as linked existential experiences through spaces rather than confined to individual buildings is more in line with our experience of the city as a series of interconnected spaces and places. Rather than describing a single, static architecture through words, how can we express this linked experience of spaces dynamically through narratives? Can writing …

Motivated Attention To Social And Nonsocial Reward Images: Examining Relations With Externalizing Risk In Children, Adaeze C. Egwuatu

Doctoral Dissertations

Children that exhibit issues with externalizing behaviors often experience maladaptive outcomes in later life. Externalizing problems during middle childhood (e.g., 6-10 years old) are linked to issues with emotion regulation, which are, in turn, caused by disrupted attention and emotion reactivity to reward. Externalizing problems during this period have also been linked diminished processing of social reward stimuli, suggesting externalizing risk in children may be reflected in contrasting patterns in processing of non-social and social rewards. However, research comparing how differences in affective processing of specific reward content (i.e. social versus non-social) patterns relate to externalizing behavior within normative development …

The Benefits Of Spatial Separation On The Cortical Representations Of Speech Sounds, Benjamin H. Zobel

Doctoral Dissertations

Spatial separation between competing speech streams reduces their confusion (informational masking) and improves speech processing under challenging listening conditions. The precise stages of auditory processing and the bottom-up and top-down mechanisms involved in this spatial release from informational masking are not fully understood. Event-related potentials (ERPs) were used to measure the cortical processing of relevant speech under conditions of informational masking and its spatial release, and to examine the preattentive and attentive mechanisms that benefit listeners. Participants were asked to detect noise-vocoded target speech presented with noise-vocoded two-talker masking speech. In separate conditions, the same set of targets were spatially …

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

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

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

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

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

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

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

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

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 …

Innovative Representations Of Light, Behaving As Both Particles And Waves, Among The Paintings Of Monet And Renoir, Charles Smith

Charles Kay Smith

Monet and Renoir, friends collaborating in open air about 1865, discovered that sunlight filtering through a canopy of tree leaves does not produce the splotches and dapples that studio artists conventionally represented at the time but circles of light. Sometimes the circles of light punctuating the shade are clear, separate and crisp, as though light is being propagated as particles, but if the pin-hole gaps between leaves are very close together, they will project compound or superimposed circles that look like the waves that Thomas Young saw in his double slit experiment in 1803-4. Newton’s Opticks published in 1704 had …

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 …

Why We Disagree: Morality And Social Categorization, Nathan Christopher Carnes

Masters Theses

Recent research has identified important functional differences between Prescriptive morality (based in approach motivation) and Proscriptive morality (based in avoidance motivation). The purpose of the present research was to understand the consequences of these moralities applied at the group level for social categorization, especially in response to threat. I measured social categorization with a novel method in which participants categorized same-race and cross-race morphed faces. Social Justice (which is Prescriptive morality applied to the group) was associated with more inclusive social categorization under conditions of threat compared to a control condition. Social Order (which is Proscriptive morality applied to the …

Memory And Production Of Standard Frequencies In College-Level Musicians, Sarah E. Weber

Masters Theses 1911 - February 2014

This thesis examines the nature of long-term absolute pitch memory—an ability traditionally assumed to belong only to absolute pitch (AP) possessors—by testing for evidence of this memory for “standard” frequencies in musicians without AP. Standard frequencies, those based on the equally tempered system with A = 440 Hz, are common in the sonic environment of the Western college musical education, and thus could have the opportunity to penetrate listeners’ long-term memories. Through four experimental tasks, this thesis examines musicians’ ability to recognize and produce frequencies from the set of equally tempered frequencies based on A = 440 Hz, without regard …

Children's Cancer And Transplant Hospital: A Micro Town Within A Bubble, Kimia Samimi

Masters Theses 1911 - February 2014

As the greatest considerations in health-care design have traditionally been functional —hygiene, efficiency, and flexibility for changing technology— hospitals have evolved to become dehumanizing spaces. In this thesis two specific groups of chronically ill children who have among the longest inpatient stays are studied: cancer and organ transplant patients. Being under immunosuppressive drugs, these children are physically vulnerable thus are kept completely isolated. These long stays and isolation can be very depressing for them.

This thesis undertakes the challenge of designing a fully isolated space that doesn’t feel like one or in other words “a micro-town within a bubble”. The …

America's Changing Face: Differential Effects Of Colorblindness And Multiculturalism On Racial Categorization And Stereotyping, Melissa A. Mcmanus

Masters Theses 1911 - February 2014

Two studies were conducted to explore the effects of the sociopolitical ideologies colorblindness and multiculturalism on perceivers’ (1) automatic awareness of race and (2) automatic racial stereotyping. Study 1 showed that a colorblind prime caused White perceivers to notice White targets’ race more compared to a no prime condition, although non-White perceivers were able to ignore race when primed with colorblindness. Multiculturalism, on the other hand, caused individuals to notice race no differently than the control. In terms of stereotyping, Study 2 showed that a colorblind prime did not change automatic stereotyping of Black or White targets. In contrast, multiculturalism …

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 …

The Other-Race Effect And Its Influences On The Development Of Emotion Processing, Alexandra Monesson

Masters Theses 1911 - February 2014

The theory of perceptual narrowing posits that the ability to make perceptual discriminations is very broad early in development and subsequently becomes more specific with perceptual experience (Scott, Pascalis, & Nelson, 2007). This leads to the formation of biases (Pascalis et al., 2002; 2005; Kelly et al., 2007), including the other-race effect (ORE). Behavioral and electrophysiological measures are used to show that by 9-months-of-age, infants exhibit a decline in ability to distinguish between two faces from another race compared to two faces from within their own race. Significant differences in the P400 component revealed a dampening of response to other-race …
