The CPH is often cited to account for differences in success between early and late language learners. Based on Lenneberg's hypothesis, other researchers have generated additional hypotheses, all of which consider a maturational period of time during which language acquisition can take place. This thesis investigates the critical period hypothesis for second language (L2) proficiency from English as a foreign language perspective. It investigates whether it is possible for late learners of English to achieve a native-like proficiency regardless of the starting age or the amount of exposure, also we will investigates whether the variable the earlier the better' can influences the ability of L2 learners to obtain better performance. In order to investigate this variable to late L2 learners of English, a groups of high school learners with the same amount of exposure to the English language and the French language will be observed in their classroom and see how well they perform a set of tests in both English and French. This paper examines the Critical Period Hypothesis in second language acquisition. Studies assessing learners’ native likeness in grammatical features as well as pronunciation are examined for evidence in support of or against the critical period. This paper also evaluates the level of proficiency in third year high school students in English (starting at age of 11) and in French (starting at age of 08). We set to establish that there should be a relationship between age of onset (start of CPH) and better language performance conforming to the features of a critical period and that early second language learners can achieve native like proficiency. To test these hypothesis we tested a group of third year of high school in six activities three in French and three in English in Al Arbi Ben Mhedi high school, and the results showed an advantage in French over English which comes to no surprise when we consider the difference in the starting age of both languages. 4 List of T ables Functions of H and L varieties…………………………………...60 Descriptive Statistics Grammar test (English)……………………89 Descriptive Statistics Grammar test (French)…………………….89 Descriptive Statistics Dictation test (English)…………………….90 Descriptive Statistics Dictation test (French)……………………..90 5 List of D iagrams Algerian bilingualism……………………………………………………………….78 6 Table of contents 1 Introduction…………………………………………………………………………………………… ……………01 1.1 Statement of the problem……………………………………………………………………………………02 1.2 Significance of the study………………………………………………………………………………………02 1.3 Aim of the study…………………………………………………………………………………………………..02 1.4 Research Questions……………………………………………………………………………………………..03 1.5 Hypothesis………………………………………………………………………………………………… ………..03 1.6 Structure of the study…………………………………………………………..................................03 1.7 Methodology……………………………………………………………………………………………… ……….03 2 CHAPTER I……………………………………………………………………………………………………………05 2.1 An Introduction to the Critical Period Hypothesis………………………………………………..06 2.2 Types of Hypotheses……………………………………………………………………………………………10 2.3 Recent Research on Late Beginners……………………………………………………………………..15 2.4 Early Foreign Language Programs…………………………………………………………………………20 2.5 Target Languages………………………………………………………………………………………………….21 2.6 Individual Differences…………………………………………………………………………………………...23 2.7 Early versus Later Start………………………………………………………………………………………….25 2.8 Continuity and Transfer………………………………………………………………………………………...28 2.9 Teachers of young learners……………………………………………………………………………………30 2.10 Conclusion………………………………………………………………………………………………… …………..32 3 CHAPTER II……………………………………………………………………………………………………………..33 3.1 Introduction………………………………………………………………………………………………… ………..33 3.2 Early Studies Examining Cognitive Development……………………………………………………34 3.3 Recent Studies Examining Cognitive Development………………………………………………..36 3.4 Cognitive Development and Degree of Bilingualism………………………………………………40 7 3.5 Bil ingualism and Cognitive Processes…………………………………………………………………….42 3.6 Sociocultural Context of Bilingualism…………………………………………………………………….44 3.7 A Case for Bilingual Instruction in Early Childhood…………………………........................45 3.8 Neuroimaging studies on age and proficiency in L2 acquisition…………………………….49 3.9 CONCLUSION…………………………………………………………………………………………… ……………56 4 CHAPTER III………………………………………………………………………………………………………….57 4.1 Introduction……………..................................................................................................57 4.2 Today’s linguistic situation in Algeria……………………………………………………………………..58 4.3 Attitudes to the languages in contact…………………………………………………………………….62 4.4 Social variables related to bilingualism…………………………………………………………………..63 4.5 The national problem……………………………………………………………………………………………..64 4.6 The official position of Arabic and French in Algeria……………………………………………….68 4.7 Present day community in Algeria………………………………………………………………………….71 4.8 The problems of the multi-lingual Algerian child…………………………………………………….73 4.9 Political conflict between two languages…………………………………………………………….….76 4.10 Conclusion………………………………………………………………………………………………………… ….79 5 CHAPTER IV…………………………………………………………………………………………………………..81 5.1 Introduction………………………………………………………………………………………………………… ….81 5.2 Population………………………………………………………………………………………………………… ….…82 5.3 The linguistic background of the students……………………………………………………………….83 5.4 Description of the tests……………………………………………………………………………………………87 5.5 Administration of the tests………………………………………………………………………………………88 5.6 The results………………………………………………………………………………………………………………. 89 5.7 CONCLUSION………………………………………………………………….………………………………… ……..92 6 CONCLUSION………………………………………………………………………………………………… ……93 8 Appendix A……………………………………………………………………………………………………………97 Appendix B……………………………………………………………………………………………………………99 Appendix C………………………………………………………………………………………………………….101 Appendix D………………………………………………………………………………………………………….102 References………………………………………………………………………………………………………….. 103 9 Introduction The role of the age factor and the existence of a critical period (CP) is a key research area in second language acquisition (SLA) research and, as Hernandez, Ping and MacWhinney point out, “the idea of a biologically determined critical period plays a essential role not just in linguistic theory, but in cognitive science as a whole” (2005, p. 220). Cognitive approaches to and neurobiological explanations of SLA have recently emphasized a distinction between processes interacting in the development of language proficiency in line with the procedural/declarative dimension widely accepted in cognitive science (e. g., MacWhinney, 2005; Paradis, 2004; Ullman, 2001). According to Paradis, the CPH “applies to implicit linguistic competence. The decline of procedural memory for language forces late second-language learners to rely on explicit learning, which results in the use of a cognitive system different from that which supports the native language” (2004, p. 59). The acquisition of implicit competence is affected by age in two ways: (1) biologically, the plasticity of the procedural memory for language gradually decreases after about age 5; (2) cognitively, reliance on conscious declarative memory increases both for learning in general and for learning a language from about age 7. CP can be “masked to some extent by compensatory mechanisms. To the extent that proficient L2 is sub served by declarative memory, like vocabulary, it is not inclined to the CP,” (Paradis, 2004, p. 60). This hypothesis is further supported by studies on exceptionally successful adult learners, as most of them seem to possess unusual memory capacity (Skehan, 1998, p. 233; Ioup, Boustagui, Tigi, & Moselle, 1994). Later learners compensate by relying more heavily on metalinguistic knowledge and pragmatics (Paradis, 2004). Statement of the problem The problem in second language classrooms is the question if it is possible for late learners of second language to acquire and perform in an ideal level of such that is similar to that of native speaker, it at least calls into question the strength of the CPH if not its existence and is learning a wholly unfamiliar language system with different structures, linguistic features and underlying mental concepts a reachable goal for the older learners, and is earlier start of exposure the targeted language can improve the overall competency, for that I am going to observe third year students of high school and their performance inside the classroom as they try to take a test and try to interact in the targeted language. 10
