ABSTRACT The present study has concentrated on the relationship between language variation and social structure of society. It has taken into account language usage of speakers and their social background, namely social class and gender. In order to clarify this relationship,the research has been conducted in Turkish society, in particular, Istanbul, and in the Turkish language. The sociolinguistic view adopted advocates the view that language change is the result of the combination of the internal linguistic factors and external social factors. Thus, a brief overview of internal linguistic rules of /h/ deletion in the Turkish and the external social factors in the Istanbul society has been determined. A broad picture of the relationship between the internal rule of language variation and the social structure of the society is provided, as well as a discussion of some controversial issues related to language and its social context. The data for the present study shows that /h/ is a differentiator of social classes and gender in Istanbul. It is worth noting here that the reason of the discrepancy between the speech pattern of the male and female is answered by adopting the term “habitus” as a biopsychosocial process to sociolinguistics. In conclusion, the present study, like many previous studies, demonstrates that language is deeply attached to the social structure of society.

Prior research in L2 reading has shown that adult ESL readers tend to lack in the use of reading strategies, failing to utilize contextual clues or their background knowledge base. In addition, studies demonstrated that when the adult readers who are highly competent in L1 reading read in L2, they become inefficient, "text-bound" readers, failing to utilize their effective reading strategies in L1. The present study investigated adult L2 readers' processes of reading in relation to their perceived view of L2 reading, in an attempt to explore the underlying factors related to "text-bound" processing in L2 reading. Two specific research questions were raised for investigation: (1) what is the relationship between an L2 reader's perceptions about L2 reading and his or her reading processes in L2?; (2) what is the relationship between an L2 reader's perceptions about reading (both in L1 and L2) and his or her transfer of reading strategies from L1 to L2 reading? A significant correlation between the perception and actual processing pattern was hypothesized for both questions within the three theories of reading: the metacognitive, the psycholinguistic, and the schema/interactive theory. These three theories of reading provided the theoretical bases for the study. The study consisted of two phases. In the first phase, a survey was conducted with 139 adult ESL readers who responded to a questionnaire developed to tap L2 readers' perceptions about reading and their actual processes while reading magazines in English. Their responses were statistically analyzed to test the research hypotheses. In the second phase, a case study method was utilized for further exploration with six readers chosen from the survey's respondents. Two meetings with the researcher were held with each of the six subjects to further probe their perceptions about L2 reading, and their actual reading processes while they read an article from a chosen magazine. The results indicated that the more linguistic perceptions an adult L2 reader has, the more text-based processing he or she employs. It was also found that the greater the difference perceived by the reader between L2 and L1 reading, the greater the difference between his or her interaction and transaction with L2 text compared to L1 text.

Intellectually normal young children learn to request absent but needed objects which they are able to name. The primary focus of my study of child language in context was to assess the motivational effect of operation or stimulus preference on Lhe rate of toy request acquisition and the formation of stimulus classes (stimulus equivalences) . Of 13 21- to 37- month-old day-care children screened for generalized request responses (novel requests) , 1 girl and 4 boys participated in the training program because they were unable to request. Two of 4 children who completed training showed some support for the effect of preference for two two-stimulus operations on request response acquisition. All 4 children emitted novel requests to generalization probes following request acquisition criterion for one most and one least preferred stimulus. Preference had no observable effect on generalization of requesting to untrained stimuli. Additionally, I assessed and compared the cognitive-linguistic and adaptive-social maturity of those 5 children who were unable and those 8 who were able to request during preliminary request screening. The trained children tended to have a greater difference between their measured receptive and expressive language skills, and also they tended to have slightly lower scores on the Vineland Adaptive Behavior Scales: Communication, Daily Living Skills, Socialization, and Motor Skills Domains. I also tested the efficacy of a natural language paradigm using a distributed skills trial sequence with interspersed trials of known-items as an extension of Tidwell's (1986) matching-to-sample, errorless learning procedure. Four within-subject replications of successful operation, name, and request acquisition are reported across 8 operations in support of his response chain methodology. I suggest that a battery of most of the developmental measures and request screening and training procedures tested in my study might be used by behavioral interventionists to assess and remediate delayed and/or inappropriate requesting among young normally developing children in a day-care setting.

This project sought to identify methods that will work best for Second Language (ESL) adults and identify ways in which ESL can be taught to help facilitate learning for the older adult over 40 years of age. This project identified some of the problems caused by the nature of the English language and the grammatical issues older ESL students face when attempting to learn to speak and read English.

In Second Language Acquisition (SLA)literature there has been a considerable theoretical debate over the issue of teachers’ use of the students’ first language, a phenomenon sometimes referred to as ‘code-switching’. Yet to date there has been little study of the effect of teachers’ use of code-switching (CS) on the second language learning itself. Therefore the aim of this research was to study the effect of teachers’ CS on the learning of English word meanings by two age groups – 19- and 12-year–old EFL students in Korea. To this end, this study implemented a quasi-experimental design but conducive to ecological validity, drawing on intact EFL classrooms of two kinds: one with monolingual English teachers (English-only condition) and the other with bilingual teachers who speak mainly English but occasionally switch to Korean to explain unknown English words (CS condition). Under these two different instructional types, the participants – 286 adult and 443 young learners – were encouraged to learn previously unknown English words, drawn from reading texts, through their teachers’ explanations. The study also employed a participant questionnaire and follow-up interviews, so as to shed light on the issue of teacher CS from the learners’ perspective. The results reveal that, for both age groups, the teachers’ CS by and large yielded better learning results, in terms of vocabulary gains, than English-only instruction. However, an inspection of the effect sizes further shows that young learners, compared with adult ones, might benefit from the CS environment to an even greater degree in the learning of vocabulary. The findings from the questionnaire and interviews further suggest that this differential effect of teachers’ CS might be due to the young learners’ overwhelming preference for teachers’ CS in learning English. These differences both in results and learner perceptions are explained as resulting from proficiency levels on the one hand and levels of learning experience on the other. Having discovered these differential effects of teachers’ CS on the two age groups, the findings of the present thesis call for a reconsideration of pedagogical decisions regarding L2-only instruction, in particular for young L2 learners.

A recent phenomenon widely noted among international volunteer agencies and church mission boards is an increase in the number of older adults offering service in foreign countries. To be effective, these people often need to learn a new language. However, much evidence has shown that older adults have a more difficult time than their younger adult counterparts in acquiring a second language.The case studies in this ethnography describe the language learning experiences of 26 adult students of Spanish during their first trimester at a language school in Central America. Most were planning some type of missionary service in Latin American countries after graduation. There were nine younger learners (20-39 years of age), eight middle-aged learners (40-49) years), and nine older learners (50-65 years). The research centered on these students' language learning self-image and expectations for success. The purpose was to learn more about what happens to adults, especially older learners, as they attempt to acquire a second language in a school located in a naturalistic setting and where classes are comprised of learners of mixed ages. Factors relevant to success and failure were investigated in the hope that language acquisition could be facilitated for these people.The researcher functioned as a participant-observer, taking a full load of classes and also conducting bi-weekly tape-recorded private interviews with the other 25 learners. Other data were obtained from language-learning journals and from observations of the students in their classrooms, community activities, and local homes. The teachers also shared what they had observed over the years about the characteristics of successful adult learners. A mail questionnaire was completed by 47 alumni of the school.The findings illuminated problems some learners have in balancing needs for immersion into the new culture and fellowship with same-culture classmates, finding good conversation partners in the community, obtaining useful types and amounts of error correction from native speakers, learning to shed ethnocentrism, and coping with differences between learning and teaching styles in the classroom. Specific suggestions are offered for adults wishing to obtain the most from their language school investment. / Department of English

This dissertation considers the factors affecting the acquisition of a second language and those factors thought to be the most important in the acquisition of English as a second language. An examination of the theories of language acquisition is followed by a literature study and discussion of the factors appearing to be of importance in second language acquisition. The account of the empirical investigation, conducted in an English medium school in Botswana, includes the formulation of hypothesis, discussion of the sample, a description of the measuring instruments used and a summary of the general procedure followed. The results of the empirical investigation suggest that the most important factors in the acquisition of English as a second language are age, intelligence, the amount of English spoken at home, pupil perception of parental support and first language acquisition. In conclusion, some of the educational implications of this investigation are considered. / Psychology of Education / M. Ed. (Psychology of Education)

PhD (Psychology) / Department of Psychology / The aim of the study was to develop a conceptualized model that will enhance language acquisition of children between 0 and 3 years. Language is a use of words and symbol to convey message, or communication. Generally, from birth to the age of four months children express their needs through crying and are soothed by the sound of voices or by low rhythmic sounds. When adults talk to children, children later imitate adult’s tongue movements and start to make sounds, coos and gurgles. Providing children with developmental stimulation and exposing them to learning opportunities increases their cognitive and social-emotional skills/abilities. Strategies to enhance language development are fundamental in children and can reduce many literacy related problems in later childhood. The objectives of the study are: to describe activities done by caregivers to influence language development; to identify factors that influence language development; to describe the importance of language development and to explain the disorders that are associated with language development. This study was qualitative in nature and it utilised an explorative design. This research design enabled the researcher to investigate the nature of acquisition comprehensively as well as the development of language and other factors that are related to it. The study was conducted at Vhembe District Municipality. Three villages were selected, namely Tshikuwi, Tshirolwe and HaMatsa villages, which are found in Makhado Municipality under Limpopo Province, South Africa. Purposive sampling was used to sample participants for the study. The individuals selected were those judged to have certain special characteristics as well as the ability to provide in-depth information for the purpose of the study. Thirty participants were selected to participate in the study. The semi-structured face to face interview and the interview guide with open-ended questions were used for data collection. Pre-testing of the interview guide was done to check if the guide would produce the expected results, three women from three different villages were selected for pretesting. All questions in the interview guide were addressed during data collection. Collected data were transcribed and analysed using thematic content analysis. The study adhered to the following research ethics: informed consent, anonymity, confidentiality, voluntary participation, no harm to the participants and dissemination of results. The study revealed that language is an important tool which is used to convey information from one person to the other. The findings indicate that language helps children to communicate and relate with other people. Language was also explained as a tool which is used to educate children, either at school or at home. The study shows that when children are learning language, they will also be stimulating their reasoning, thinking and problem-solving skills. In addition, it was also indicated that cognitive development reduces problems such as poor language development, a low self-esteem and isolation. The findings of this study show that there are a number of activities that can be used by caregivers and parents to foster the development of language in children. Those activities include, communicating with a child, reading of books, watching TV, naming of objects and explaining meaning of words. The study also identified several environmental factors that can be used to foster the development of language in children. The following environmental factors were identified in the study: communication, parental level of education, home socioeconomic status, caregiver’s personality and the availability of other children in the family. Lastly, the findings show that there are many disorders that may affect the development of language in children. The language disorders that the study identified include expressive language disorder, dyslexia, and inability to understand spoken. However, the study also reveals that these disorders may be treated. The findings of this study lead to the development of a conceptualized model to facilitate language acquisition in children between 0 and 3 years was developed. The meaning of one concept, namely reinforcement was explained in detail, in order for users of the model to understand its operational definition in the model. Reinforcement was explained because it has a diversity of meanings. The model enabled the researcher to create a link between research and what is happening in a society. Model validation was done to verify if the developed model relates to practical life, research and language development. The model for this study was validated for its applicability and usability. The drafted model was given to psychologists, speech therapists and parent to determine its usability and applicability. Keywords: language, language acquisition, language development model, language disorders. / NRF
