Attrition And Assimilation: The Neural Mechanisms Of Mandarin-English Bilingualism, Natalie Paige Robison

University Honors Theses

This line of research investigates attrition of native language (L1) Mandarin proficiency with increasing proficiency in English. English uses pitch to denote intonation (e.g., "it's there?" versus "it's there!"), while Mandarin additionally uses pitch to indicate word meanings; e.g., /he/ means "drink" when spoken with a high, level tone, or "river" when spoken with a rising tone. The present study delineates between two alternative explanations for the prior finding that English proficiency correlates with attrition of Mandarin tones, but not Mandarin vowels. This pattern could be explained by 1) assimilability of the Mandarin vowel contrasts used in the study into …

Happy ��, Sad ��Or Pizza ��: A Review Of Emoji Effects On Reading Times And Their Relation To Mood, Fetheya Alattar

University Honors Theses

With recent advancements in technology, emoji are continuously changing the way that people communicate and process language. Their use continues to evolve as a mechanism to counter the loss of the rich nonverbal cues of face-to-face communication. Subsequently, the need for research examining how emoji are processed and how they affect language and communication has become more important. This research specifically examines the scholarship on emoji effects on sentence reading times (RT) and how this relates to mood. Results on the effects of emoji on sentence RT are mixed. In some instances, emoji slowed RT and in others, they sped …

Posterior Predictive Critique Of A Psychometric Bayesian Model For Assessing Aphasia, Ashlynn Crisp

Mathematics and Statistics Dissertations, Theses, and Final Project Papers

For persons with aphasia, naming tests are useful for assessing the severity of the disease and observing progress toward recovery. The Philadelphia Naming Test (PNT) is a leading naming test composed of 175 items. The items are common nouns which are one to four syllables in length and with low, medium, and high frequency. Since the target word is known to the administrator, the response from the patient can be classified as correct or an error. If the patient commits an error, the PNT provides procedures for classifying the type of error in the response. Item response theory can be …

Investigating Metrical Context Effects On Anticipatory Coarticulation In Connected Speech Development, Jillian Adkins, Christina Gildersleeve-Neumann, Melissa A. Redford

Speech and Hearing Sciences Faculty Publications and Presentations

If rhythm acquisition is influenced by the development of articulatory timing, then metrical structure might be expected to condition this timing. This study tested this hypothesis by investigating anticipatory effects of an upcoming noun on the production of a preceding determiner, under the assumption that anticipatory coarticulation indexes chunking. Simple S-V-O sentences were elicited from 5-year-olds, 8-year-olds, and adults. The V was either monosyllabic packed or disyllabic patted. The O was a determiner phrase where nouns varied either in onset place-of-articulation (POA; tack vs. cat) or in their rhymes (tack vs. toot). Acoustic analyses of determiner schwa F1 and F2 …

Revealing Subtle Cognitive-Linguistic Differences In Adults With Mild Traumatic Brain Injury Through Discourse Analysis, Amanda L. Weichselbaum, Sarah E. Key-Delyria

Student Research Symposium

Discourse abilities of individuals with traumatic brain injury presented at the Portland State University Student Research Symposium.

The findings of this study support the idea that discourse analysis may be a useful tool for determining subtle, cognitive-communication deficits in the TBI population that common neuropsychological tests may not detect. Such information may be important clinically for validating persisting cognitive symptoms and guiding effective therapy goals. Linguistic disruptions may reveal cognitive impairments due to diffuse damage of the brain.

Research Proposal For Study: Can Artifical Emulation Of Synesthesia Aid Visual Word Recognition?, Lucas Charles

Anthós

The field of synesthesia has largely been unexplored beyond mere analysis of the condition and only a few papers on the topic of new applications have been published within the last decade. The condition can potentially provide great benefits to the study of the psychology of language along with its role in language use itself. As understanding of this condition continues to grow, one can draw links between it and its effect on language use, thereby enabling a greater understanding of the language process itself. Synesthesia involves the stimulation of one sense along with involuntary activation of another sensory pathway. …

The Acquisition Of A Stage Dialect, Nathaniel George Halloran

Dissertations and Theses

This study reports on the effectiveness of (theatrical) stage dialect learning techniques in bringing about linguistically authentic change. Actors use several techniques, some rather esoteric in nature and others more closely tied to linguistic fact such as the use of the International Phonetic Alphabet. The purpose of this study is to examine some of these techniques as to their ability to bring about linguistic authenticity, as well as to attempt a comparison of stage dialect acquisition and naturalistic dialect acquisition.

Data were collected by interviewing a convenience sample of twelve student actors. Six of these (three males, three females) were …

Contingencies Governing The Production Of Fricatives, Affricates, And Liquids In Babbling, Christina E. Gildersleeve-Neumann, Barbara L. Davis, Peter F. Macneilage

Speech and Hearing Sciences Faculty Publications and Presentations

Studies of early-developing consonants (stops, nasals, and glides) in babbling have shown that most of the variance in consonants and their associated vowels, both within and between syllables, is due to a "frame" produced by mandibular oscillation, with very little active contribution from intrasyllabic or intersyllabic tongue movements. In a study of four babbling infants, the prediction that this apparently basic "frame dominance" would also apply to late-developing consonants (fricatives, affricates, and liquids) was tested. With minor exceptions, confirming evidence for both the predicted intrasyllabic and intersyllabic patterns was obtained. Results provide further evidence for the frame dominance conception, but …

A Critique Of Bandler And Grinder's Method Of Mapping Representational Systems, Leslie E. Goldmann

Dissertations and Theses

People perceive the world in their own terms: our use of language reflects our perceptions. The way in which we perceive the world and the words we use to reflect that perception Grinder and Bandler (1976) call a "representational system." The authors isolate three types of representational systems, visual, kinesthetic, and auditory, and they present a technique for mapping these systems. These authors state that a sensory preference profile can be mapped accurately and reliably via an individual's use of language. For example, words such as "clear," "see" and expressions of the kind "I get a picture" would connote a …
