Studies in Second Language Acquisition and Neurolinguistics have argued that adult learners when dealing with certain phonological features of L2, such as segmental and suprasegmental ones, face problems of articulatory placement (Esling, 2006; Abercrombie, 1967) and somatosensory stimulation (Guenther, Ghosh, & Tourville, 2006; Waldron, 2010). These studies have argued that adult phonological acquisition is a complex matter that needs to be informed by a specialized sensorimotor theory of speech acquisition. They further suggested that traditional pronunciation pedagogy needs to be enhanced by an approach to learning offering learners fundamental and practical sensorimotor tools to advance the quality of L2 speech acquisition.



This foundational study designs a sensorimotor approach to pronunciation pedagogy and tests its effect on the L2 speech of five adult (late) learners of American English. Throughout an eight week classroom experiment, participants from different first language backgrounds received instruction on Articulatory Settings (Honickman, 1964) and the sensorimotor mechanism of speech acquisition (Waldron 2010; Guenther et al., 2006). In addition, they attended five adapted lessons of the Feldenkrais technique (Feldenkrais, 1972) designed to develop sensorimotor awareness of the vocal apparatus and improve the quality of L2 speech movement. I hypothesize that such sensorimotor learning triggers overall positive changes in the way L2 learners deal with speech articulators for L2 and that over time they develop better pronunciation.

After approximately eight hours of intervention, analysis of results shows participants’ improvement in speech rate, degree of accentedness, and speaking confidence, but mixed changes in word intelligibility and vowel space area. Albeit not statistically significant (p >.05), these results suggest that such a sensorimotor approach to L2 phonological acquisition warrants further consideration and investigation for use in the L2 classroom.

This thesis investigates similarities in the diachronic sound changes found in Eastern Old Japanese dialects and in Ryukyuan languages and tests a hypothesis of language contact. I examine three sound changes attested in the Eastern Old Japanese corpus of Kupchik (2011). These three are denasalization of prenasalized obstruents, the fortition of the labial glide [w] and prenasalized / simple voiced fricative [(n)z], and the irregular raising of Eastern Old Japanese mid vowels. Extralinguistic and linguistic evidence is presented in support of a hypothesis for language contact between 8th century Ryukyuan speakers and Eastern Old Japanese speakers. At present, many assumptions bog down any potential evidence of contact. However, cases where reconstructed Ryukyuan could have donated a form into EOJ do exist. With future research into early Ryukyuan development and the lexicons, phonologies, and syntactic patterns of Ryukyuan languages, more can be said about this hypothesis. Alongside testing a hypothesis of language contact, this thesis can also be viewed as an analysis of Eastern Old Japanese spelling variation of the three changes mentioned above.

This thesis offers a contrastive analysis of the causative alternation phenomenon in English and Standard Arabic variety. This phenomenon has received a lot of attention in the literature on argument structure. It has traditionally been presented in terms of the causativization of inchoative verbs/unaccusatives. It is argued here that this analysis conflicts with the way the causative alternation is molded in Arabic. Causative alternation in Arabic is not only limited to inchoative verbs, but it incorporates unergative verbs as well, which play a vital role in this alternation. The implication of this observation is that the different syntactic behaviors between English and Arabic may reflect people’s different perception of events and lead to different syntactic computation. Therefore, this thesis highlights the role of this subset of intransitives/anti-causatives in the Arabic causative alternation and answers one of the highly considered questions on the causative alternation; that is, which version of the alternation is the lexical base, and which one is derived? This thesis also reveals that there is some significant difference between English and Arabic in terms of the alternatability of unaccusative verbs. Therefore, this study shows that most of the Arabic unaccusative verbs, except denominal verbs, have a causative alternant. This thesis also addresses the vital role of the Arabic verbal template in clarifying this phenomenon. In sum, this thesis provides an overview of the semantic, syntactic, and morphological properties of Arabic verbs undergoing the causative alternation. Besides employing the researcher’s native-speaker intuition, the English/Arabic Lexicon Dictionary and Arabicorpora are consulted to support the validity of the argument.

Arabic is widely known for the lack of copulas in nominal sentences in the present tense. Arabic employs a copula ‘kana’ in the past and future tenses. However, in some constructions the presence of a third person pronoun is necessary for the purpose of emphasis or ambiguity reduction. The data investigated in this thesis was from Classical Arabic, Standard Arabic, and the Western Saudi ‘Hijazi’ dialect. The thesis briefly discussed the grammaticalization of a transitive verb to a non-present tense copula in Classical Arabic. In addition, the thesis discussed the process of copularization that was a result of grammaticalization of the demonstrative third person pronoun ‘huwa’ to a present tense copula in Standard Arabic. It was shown that the pronoun went through a process of reanalysis from the specifier to the head position of PredP driven by Feature Economy and the Head Preference Principle. The result was the loss of the person feature. The new copula developed and attached to the negative particle ‘ma’ in the Hijazi dialect losing all its phi-features. These phenomena are known as the copula and negative cycles, respectively. The analysis was based on the Generative Grammar framework and the Minimalist program. This study attempted to shed light on Arabic copulas and contribute to more understanding of the use of these copulas in question and negative constructions. It may also help in typological studies, which may lead to a better understanding of the linguistic theory and the language faculty.

ABSTRACT

The absence of the consonant sound /p/ in Libyan Arabic leads Libyan speakers of English to pronounce /p/ as /b/. This study examines how Libyan Arabic speakers distinguish the English /p/ and /b/ in their production of L2 English. The study also examines the effect of the production contexts and the learning environment on two groups of Libyan Arabic speakers' attainment of the English /p/ in the USA and Libya. The study collected voice recordings of word-initial /p/ and /b/ in isolated-words, minimal pairs, and sentences in English from both Libyan Arabic speakers and American English speakers. The study also collected Libyan Arabic stop consonants /b/, /t/, /d/, /k/, and /g/ from the Libyan participants. The voice recording data were collected using the WhatsApp mobile application from all participants and the Libyan Arabic participants were also asked to fill an online survey. Using voice onset time (VOT) as a measurement tool, this study measured the English and Libyan Arabic data through Praat software. The findings show that most Libyan Arabic participants distinguish between /p/ and /b/, but they did not have as high VOT averages as the American participants' /p/. It also reveals that the production context, especially in minimal pairs and sentence contexts, has an effect on their participants' production. However, the learning environment does not have an effect on the Libyan participants' pronunciation of /p/ in this study.
