11	Correlations Between Vowel Lengths and Emotion in Narratives Diaz, Brett Anthony 01 September 2015 (has links) This paper looks at the relationship between emotion and vowel length in spontaneous speech, specifically during narratives. It is hypothesized that during emotionally-laden speech, vowel length will be longer in duration than when in non-emotional speech. Data is drawn from the Univerisity of California, Santa Barbara linguistic corpus, with conversations focused on individuals in and around Southern California. The paper builds on work by Dabbs et al., Banse & Scherer, Estes & Adelman, and others regarding the nature of cognitive monitoring, as well as stance as discussed by Ochs & Schieffelin, Ochs, Kärkkainen, Local & Walker, and how emotion is displayed in speech. Tokens chosen for analysis are /ɑ/, /ɑɪ/, and /ə/. Three of each token in first syllable position is collected for analysis from both emotional and non-emotional speech. Analysis of tokens then takes place by (mean) averaging each token's length for each speaker in each stance, then the total vowel average time is calculated again for each speaker in each stance. Beyond intra-vowel, intra-speaker averages, inter-speaker average is calculated to assess consistency of the vowel length changes between stances. The paper finds that the length of tokens shows an average increase during intraspeaker emotional speech.

12	Investigating Miami English-Spanish Bilinguals' Treatment of English Deictic Verbs of Motion Verde, Erica 27 March 2014 (has links) This investigation focused on the treatment of English deictic verbs of motion by Spanish-English bilinguals in Miami. Although English and Spanish share significant overlap of the spatial deixis system, they diverge in important aspects. It is not known how these verbs are processed by bilinguals. Thus, this study examined Spanish-English bilinguals’ interpretation of the verbs come, go, bring, and take in English. Forty-five monolingual English speakers and Spanish-English bilinguals participated. Participants were asked to watch video clips depicting motion events and to judge the acceptability of accompanying narrations spoken by the actors in the videos. Analyses showed that, in general, monolinguals and bilinguals patterned similarly across the deictic verbs come, bring, go and take. However, they did differ in relation to acceptability of word order for verbal objects. Also, bring was highly accepted by all language groups across all goal paths, possibly suggesting an innovation in its use.

13	Examining the Intersection of the Cognitive Advantages and Disadvantages of the Bilingual Brain Rabkina, Irina 01 January 2014 (has links) Two conflicting findings characterize cognitive processing accompanying bilingualism. The “bilingual advantage” refers to improved cognitive performance for bilingual compared to monolingual participants. Most bilingual advantages fall under the umbrella of cognitive control mechanisms, most frequently demonstrated using the Stroop task and the Simon task (e.g., Bialystok, 2008; Coderre, Van Heuven, & Conklin, 2013). The “bilingual disadvantage,” on the other hand, refers to bilinguals’ diminished performance on tasks that require word retrieval or switching between languages. This study examined the intersection of the bilingual advantage and the bilingual disadvantage to investigate whether they stem from a single cognitive control process. The bilingual advantage was measured as speech onset time differences between monolingual and bilingual participants in the Stroop task after being primed in the same language (i.e., English prime and English Stroop for monolinguals, and either English prime and English Stroop or Spanish prime and Spanish Stroop for bilinguals). The bilingual disadvantage was measured as differences in bilingual participants’ speech onset times between the same-language conditions described above and cross-language conditions (i.e., either English prime and Spanish Stroop or Spanish prime and English Stroop). Monolinguals performed better than bilinguals did on the same-language Stroop [F(3,1) = 83.5, p < 0.001, MSE = 15415], so a bilingual advantage was not demonstrated. However, bilinguals did perform better in same-language blocks than cross-language blocks [F(7,3) = 24.6, p < 0.001, MSE = 22648]. This suggests that the current protocol successfully elicits the bilingual disadvantage. Further research is needed to evaluate whether the same cognitive control processes are responsible for the two effects. Possible extensions of this work include observing a larger number of participants to rule out between-subjects effects and using a button press rather than spoken response during the Stroop task. bilingualism bilingual advantage bilingual disadvantage Stroop Cognition and Perception Cognitive Neuroscience Cognitive Psychology First and Second Language Acquisition Psycholinguistics and Neurolinguistics
14	The Dynamic Role of Subphonemic Cues in Speech Perception: Investigating Coarticulatory Processing Across Sound Classes Arbour, Jessica 10 1900 (has links) <p>Neural responses to anticipatory coarticulatory cues were investigated across systematically varying phonological conditions. Congruent or incongruent subphonemic information was placed between an initial consonant and a vowel in a consonant-vowel- consonant (CVC) spoken word (Archibald & Joanisse, 2011). Due to physical and temporal differences across sound classes, the objective was to investigate whether coarticulatory information would be processed differently across controlled manipulations of onset (fricative vs. stop) and vowel type (height vs. backness). Event- related potentials (ERPs) were recorded during a printed-word/spoken-word matching paradigm, in which participants indicated whether a visual prime stimulus and a spoken word matched/mismatched. The “Phonological Mapping Negativity” (PMN) component provides strong evidence that the use of coarticulatory information in speech recognition varies in strength and timing as a function of onset type (fricative vs. stop) and vowel height (high vs. low). Coarticulatory cues were more readily perceived in spoken word beginning with fricatives than with stops. Similarly, subphonemic variations were more easily detected in low vowels than in high vowels. Observed perceptual and temporal differences are interpreted to reflect variations in subphonemic and phonological processing.</p> / Master of Science (MSc) Spoken Word Recognition Event-Related Potentials (ERP) Subphonemic Coarticulation Cognition and Perception Linguistics Phonetics and Phonology Psycholinguistics and Neurolinguistics Cognition and Perception
15	The Intersection of Speech-Language Pathologists’ Beliefs, Perceptions, and Practices and the Language Acquisition and Development of Emerging Aided Communicators Vento-Wilson, Margaret 25 March 2019 (has links) This dissertation discusses the convergence of aided augmentative and alternative communication (AAC) systems, the language acquisition and development of young children who are minimally verbal or nonverbal who acquire their native language while simultaneously learning to use an aided AAC system, and explicit and implicit elements that influence language outcomes. Factors investigated include those related to language acquisition universals, the AAC system, the young aided AAC user, and practices, philosophies, and beliefs of speech-language pathologists (SLPs). Further examined were: (a) language acquisition parallels in atypical populations who do not possess the full range of senses who have been shown to develop language, and (b) analogies between the linguistic structures of pidgins, interlanguages, and the syntax of young aided AAC users. This dissertation employed a survey methodology to capture the practices and beliefs of SLPs as a means of identifying potential contributing factors to the reduced linguistic outcomes of these children. Quantitative findings revealed statistically significant differences in SLPs’ perceptions of confidence and qualification with the two populations of children with language impairments who use an oral modality and young aided AAC users. Descriptive trends across all constructs measured suggested differences in SLPs’ practices, belifes, and perspectives in their work with these two populations. The analysis of the syntactic structures of the language of young aided AAC users revealed definitive parallels with the construct of interlanguages. speech-language pathologists young aided AAC users survey research language acquisition and development morphosyntax intervention practices Communication Disability Studies Morphology Psycholinguistics and Neurolinguistics Semantics and Pragmatics Syntax
16	PHONOLOGICAL PROCESSING OF VISUAL-SPEECH: THE PHONOLOGICAL MAPPING NEGATIVITY (PMN) AMPLITUDE IS SENSITIVE TO FEATURES OF ARTICULATION Harrison, Angela V. 04 1900 (has links) <p>The goal of this study was to elucidate whether articulations of visual-speech are processed phonologically, and in the same manner as auditory-speech. Phonological processing, measured through the amplitude of the Phonological Mapping Negativity (PMN), was compared across three conditions using the electroencephalogram (EEG). Planned polynomial contrasts compared conditions of related and unrelated linguistic stimuli versus a non-linguistic control stimulus. A significant Site x Condition polynomial trend at posterior sites (Pz and Oz) during the N400 tine window revealed that the unrelated condition was most negative in amplitude, an N400-like deflection in the control condition reached similar negative amplitude, while the related condition was the most positive. A significant quadratic trend of PMN amplitude differentiated between the linguistic conditions and the non-linguistic control at site Fz, but did not differentiate the related and unrelated linguistic conditions from each other. These results support a conclusion that non-lexical speech-like and gurning motions of the lips are treated differently than articulations of a meaningful nature. Moreover, the PMN response patterned similarly in the linguistic conditions, compared to the non-linguistic control, indicating phonological processing. The prediction that PMN amplitude will distinguish visual-speech events congruent or incongruent to a phonologically constrained context was not supported.</p> / Master of Science (MSc) speech processing phonological mapping negativity (PMN) electroencephalogram (EEG) phonological processing speechreading visual-speech event related potentials Cognition and Perception Phonetics and Phonology Psycholinguistics and Neurolinguistics Cognition and Perception
17	The Reflection and Reification of Racialized Language in Popular Media Wright, Kelly E. 01 January 2017 (has links) This work highlights specific lexical items that have become racialized in specific contextual applications and tests how these words are cognitively processed. This work presents the results of a visual world (Huettig et al 2011) eye-tracking study designed to determine the perception and application of racialized (Coates 2011) adjectives. To objectively select the racialized adjectives used, I developed a corpus comprised of popular media sources, designed specifically to suit my research question. I collected publications from digital media sources such as Sports Illustrated, USA Today, and Fortune by scraping articles featuring specific search terms from their websites. This experiment seeks to aid in the demarcation of socially salient groups whose application of racialized adjectives to racialized images is near instantaneous, or at least less questioned. As we view growing social movements which revolve around the significant marks unconscious assumptions leave on American society, revealing how and where these lexical assignments arise and thrive allows us to interrogate the forces which build and reify such biases. Future research should attempt to address the harmful semiotics these lexical choices sustain.
