How do infants learn the sounds of their native language? Do they need to use general-auditory or language-specific mechanisms to make sense of the distributional nature of their phonetic input? To answer this question, this study investigated the neural correlates of phonetic discrimination in monolingual and bilingual infants (2-6 and 10-14 months) and adults using a new lens afforded by functional Near-Infrared Spectroscopy (fNIRS) neuroimaging. All participants heard syllables phonetically contrastive in their native English and Hindi (non-native) in an oddball paradigm while being imaged with fNIRS. Age comparisons of infant brain activation in multiple sites revealed that left Broca‟s area showed a developmental decline in response to native-language experience only. Bilateral STG showed robust recruitment at both ages in response to both stimulus languages. These findings were robust across monolinguals and bilinguals. Together, the results suggest that all infants use neural tissue predisposed for linguistic-phonetic processing in early life.

The purpose of this study was to explore the effects of K.K.phonetic symbols-assisted instruction on students¡A English achievement and motivation for learning. A quasi-expermental design was used. The subjects were 75 sixth-grade students from elementary school.They were divided into three groups.After an English achievement Test and the scale of Motivation for Learning English,the K.K.phonetic symbols-assisted instruction was implemented .After 4 months of instruction, all groups took an English Achievement Test and the Scale of Motivation . The results were as the followings: 1. No significant difference was found between the phonics group and the phonics+K.K. phonetic symbols group in their English Achievement Test. 2. No significant difference was found between the phonics group and the phonics+K.K. phonetic symbols group in their motivation for learning English. 3. There were significant differences found between the phonics+K.K. group-consonant and vowel taught together and the phonics+K.K. phonetic symbols group-taught separately in their English Achievement Test. 4. There were significant differences found between the phonics+K.K. group-consonant and vowel taught together and the phonics+K.K. phonetic symbols group-taught separately in their motivation for learning English. Finally, based on the findings of this study, suggestions for administrators, teachers, and future research were discussed

Phonetic convergence (PC) is speech specific accommodation characterized by an increase in similarity in a dyad’s speech patterns due to an interaction. Previous research has demonstrated that PC occurs in dyads during various interactive tasks (e.g. map completion and picture matching) and in cross-linguistic conditions (e.g. dyads who speak the same or different native language) (Pardo, 2006; Kim et al., 2011). Studies suggest that speakers who are closer in linguistic distance (i.e. share the same native language) are more likely to converge than speakers who are far apart (i.e. speak different native languages) (Kim et al, 2011). However, Interdialectal conditions where speakers use different national dialects of the same language have been studied to a far lesser extent (Babel, 2010). Similarly, studies have examined both segmental and suprasegmental features that are susceptible to PC but rhythm has not been studied extensively (Krivokapic, 2013; Rao et al., 2011). Though initial studies postulated that PC is the result of either automatic or social processes, more current research suggests that a combination of both kinds of processes may be better able to account for PC (Goldinger, 1997; Shepard et al., 2001; Babel, 2009a). The current dissertation uses novel measures such as Interlocutor Similarity and EMS + centroid to implicate global properties of vowels and rhythm respectively as acoustic correlates of PC. Moreover, it finds that speakers showed both convergence and divergence in vowels and rhythm as moderated by their language background. Close interactions between native speakers of American English (AE) resulted in convergence whereas interdialectal interactions (between AE and Indian English speakers) and mixed language interactions (between native and non-native speakers of AE who are native speakers of SP) resulted in both convergence and divergence. The results from this study may shed light on how speakers attenuate the highly variable nature of speech by adapting speech patterns to aid intelligibility and information sharing (Shepard et al., 2001) and that this attenuation is moderated by social demands such as identity and cultural distinctiveness. / text

This dissertation examines the effects of semantic and phonetic radicals on Chinese character decoding by high-intermediate level Chinese as a Foreign Language (CFL) learners. The results of the main study (discussed in Chapter #5) suggest that the CFL learners tested have a well-developed semantic pathway to recognition; however, their phonological pathway is not yet a reliable means of character identification. Semantic radicals that correctly pertain to character meaning facilitated reaction time in semantic categorization tasks (Experiment #1), while radicals that had no immediately interpretable relation to character meaning had a strong inhibitory effect. The relativeaccuracy of phonetic radicals (for predicting the whole-character's pronunciation) did not measurably improve homonym recognition (Experiment #2). Subjects were then tested to determine their default processing modes in Chinese character reading. In a lexical decision task (Experiment #3) wherein semantic radicals or phonological components were blurred to delay recognition, surprisingly, the subjects were significantly slower in identifying pseudo-characters when the phonological component was blurred, indicating that, despite having unreliable phonological pathways to character recognition, the subjects were still utilizing that strategy first. These results were mirrored in a sentence reading task (Experiment #4) wherein a single character had either a blurred semantic radical or phonological component. This tendency to use the less developed pathway is explained as a default means of attempting character recognition as a result of subjects gleaning orthographic information from the densely packed phonological component and as a result of L1 (English) interference predisposing subjects to phonological decoding strategies.Such a study on CFL learner reading processes is an important step towards ameliorating CFL teaching methodologies. For this reason, the author contrasts the data on CFL learners with data taken from similar experiments with native Chinese speakers (in Chapter #6) in order to demonstrate concrete differences in character reading processes which should affect teaching practices between the two groups. The authorconcludes the dissertation by making targeted recommendations for CFL pedagogical practices based upon the results of the study on the effect of character-internal features on reading patterns by non-native readers of Chinese (Chapter #8).

The present study was designed to examine differences between subtypes of readers and spellers in their performance on several phonological, orthographic, and memory tasks. A central question involved whether subtypes of readers and spellers could be distinguished based on their performance across the tasks administered. Based on their performance on a standardized achievement test, fourth and fifth grade children (N=50) were classified as having no difficulties with reading and spelling (good readers and spellers), difficulties with spelling, but not reading (mixed readers and spellers), or difficulties with both reading and spelling (poor readers and spellers). Each student was given a series of tasks to assess their use of phonological and orthographic information for memory and spelling. These tasks included: 1) rhyme judgment, 2) cued recall, 3) reading pronounceable pseudowords, 4) deciding which of. two pseudowords looks most like a real word, and 5) reporting on the kinds of strategies used to spell words. An error analysis was also conducted. Students with reading and spelling difficulties performed consistently lower than good and mixed readers and spellers on tasks assessing their use of phonological information. Good and mixed readers and spellers were not distinguishable on these tasks. Students with no reading and spelling difficulties or with spelling difficulties only performed better than poor readers and spellers on some tasks assessing orthographic processing. Specifically, mixed readers and spellers were distinguishable from good readers and spellers by their poorer recall of visually similar words. Good and poor subtypes were not distinguishable on this task. Poor readers and spellers also achieved comparable scores to the good and mixed readers and spellers on a measure of orthographic awareness. Overall results provided evidence supporting subtypes of reading and spelling ability groups. Students with no reading and spelling difficulties, or difficulties with spelling but not reading were similar in their use of phonological information. However, students with reading and spelling difficulties were more similar to the good readers and spellers in their use of orthographic information in memory. The findings from the present study have implications to subsequent research examining spelling ability, provide further evidence of the unique processing characteristics of the paradoxical good reader but poor speller, and suggest the possibility of unique programming needs to remediate spelling difficulties in mixed and poor readers and spellers.

This thesis presents an intelligent system for tutoring phonetic transcription in introductory linguistics courses. It compares and contrasts this system with previous intelligent tutoring systems and presents an implementation of the present system. The problems and solutions encountered in implementing the system are described.Among the contributions and innovations are the fact that this system guides the student through several attempts at transcribing a word with increasingly specific feedback, and the fact that the system is organized in such a way that an instructor can add, modify or delete data at any time with no assistance required from a programmer.A significant contribution of this system lies in the fact that although there is only one correct answer for any given item to be transcribed, the possibilities for the student's responses and hence for incorrect answers must be open-ended. The student's answer will be a string that may not have the same length as the correct answer, may contain few or none of the same symbols as the correct answer, and those that it does contain may be in a different order. The student's answer is intended to correspond to the correct answer, but is known not to be an exact match. Arbitrary strings representing the student's answers must thus be matched up with the pattern of the correct answer in such a way that the system can give the student meaningful comments that will aid the student in identifying errors. The usual pattern recognition program is designed to identify instances where a match succeeds. This tutor must identify instances where the match fails as well as how it fails. / Department of Computer Science
