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 …

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 …

Recursion In Language And Number: Is There A Relationship?, Diego Guerrero

Masters Theses

Numbers are an important part of the cultural knowledge in the modern world. Its use is fundamental in the conception and development of modern science. There are different sets of numbers called numerical systems. The most frequently used numerical system is the set of natural numbers that is composed of positive integers. Natural numbers have several forms to express the cardinality; the most frequently used is the base-10 number system, it represents the number using base quantities and powers of ten. For example, the current calendar year could be expressed as 2018 ; it’s notation describes the additive and multiplicative …

Preferences In Learning "Hiragana": A Comparative Study Between Mobile Apps And Paper Worksheets, Michiko Nakada

Masters Theses

In 2020, technology is generally accepted, and we can see many people using their digital devices such as smartphones everywhere. It is easy to see how dependent we are on technology, anytime and anywhere. Mobile apps are one of the time-effective tools for our daily lives. College students in the United States are always busy with their classes and assignments, and for them, apps are not only for having fun but are also convenient, reliable, and essential supporting tools for their academic and daily lives.

This paper examines the students’ preferences in learning the Japanese writing system “Hiragana” with mobile …

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 …
