Behaviorist learning theory Behaviorist learning theory is a general theory of learning (i.e. it applies to all kinds of learning, not just language learning). It views learning as the formation of habits. The association of a particular response with a part
6、icular stimulus constituted a habit. It is formed when a particular stimulus became regularly linked with a particular response. When applied to SLA, the process of second language acquisition is regarded as a process of habit formation.5. The causes of errors according to behaviorismDifferences bet
7、ween the first and second language create learning difficulty which results in errors.Behaviorist learning theory predicts that transfer will take place from the first to the second language. Transfer will be negative when there is proactive inhibition. In this case errors will result.Errors, accord
8、ing to behaviorist theory, were the result of non-learning, rather than wrong learning.The means used to predict potential errors by behaviorists is Contrastive Analysis.6. StructuralismLanguage was viewed as a coded system consisting of structurally related elements (phonemes, morphemes, words, str
9、uctures and sentence patterns)7. What is contrastive analysis (CA)?Contrastive analysis is an inductive investigative approach based on the distinctive elements in a language. It involves the comparison of two or more languages or subsystems of languages in order to determine both the differences an
10、d similarities between them. It could also be done within one language. Contrastive analysis can be both theoretical and applied according to varied purposes.8. Contrastive Analysis Hypothesis (CAH)Contrastive analysis is a way of comparing languages in order to determine potential errors for the ul
11、timate purpose of isolating what needs to be learned and what does not need to be learned in an L2 situation.According to CAH, L2 errors are result of differences between the learners first language and the target language. The strong form of the hypothesis claims that these differences can be used
12、to predict all errors that will occur. The weak form of the hypothesis claims that these differences can be used to identify some out of the total errors that actually arise.9.difference vs difficulty“Difference” is a linguistic concept, whereas “difficulty” is a psychological concept. Therefore, th
13、e level of learning difficulty cannot be inferred directly from the degree of difference between two language systems.10. Definition of Error analysis (EA)the study and analysis of the errors made by second and foreign language learners (Longman Dictionary of Applied Linguistics, p.96).It involves c

Types of learner strategyLearning strategy, Production strategy 表达策略 Communication strategy: Communication strategies are employed when learners are faced with the ta

Classifications of learning strategy(Cohen 2006)(2) By function: Metacognitive; Cognitive; Socio-affective(3) By skill: listening, speaking, reading, wri

Meta-cognitive strategiesMeta-cognitive strategy is the planning for learning, thinking about the learning process, monitoring of ones production or comprehension, and evaluating learning after an activity is completed.16.

21、ve motivation 融合型动机is present in learners who identify with the target culture, would like to resemble members of the target culture and who would like to participate in the target culture. It is assumed to be based in the personality of the learner. Instrumental orientation工具型动机refers to those case

23、lti-componential construct:Motivation = effort + desire to achieve goal + attitudes Task motivation: the interest felt by the learner in performing different learning tasks. 19. Definition interlanguageInterlanguage is the approximate language system that the learner constructs for use in communicat
24、ion through the target language. (Larry Selinker)It is independent of both the learners first language and the target language.It suggests that learners language is between L1 AND L2 and that it is a continuum along which all learners traverse.20.Definition of fossilizationFossilization refers to th
25、e state in which the second language learners stop to learning when their internalized rule system contains rules different from the target language. That is to say, the interlanguage stops evolving towards the TL.21. Classification of fossilizationTemporary fossilization: the phenomenon is alterabl
26、e under certain conditions.Permanent fossilization This means the learners language stops evolving forever. Because stable stage is not real fossilization, so there is no real permanent fossilization.22. Causes of fossilizationInternal: Motivation; Communicative needs; Acquisition deviceExternal: Co
27、mmunicative pressure Lack of learning opportunities Feedback: positive cognitive feedbacks cause fossilization ; (e.g. “Oh,I see”)negative feedbacks help to prevent fossilization. (e.g. “I dont understand you” )23. Definition of UGCook(1985) summarizing the Chomskyan position, defines universal gram
28、mar as the properties inherent in the human mind. Universal grammar consists of a set of general principles that apply to all language rather than a set of particular rules.24. Markedness Markedness refers to the idea that some linguistic structures are special or less natural or less basic than oth
29、ers. Linguists working in the Chomskyan school suggest that linguistic rules can either be part of the core grammar (i.e. the universal rules) or be part of the periphery. Core rules are considered to be unmarked and therefore easily acquired.Periphery roles are considered to be and therefore differ
30、ent to learn.25. Krashens Monitor Model Krashens monitor model mainly consists of the following five hypothses:(1) Acquisition-Learning Hypothesis: there are two kinds of ways of learning a second language ,i.e., acquisition and learning. (2) Natural Order Hypothesis: SLA follows a universal route t
31、hat is not influenced by factors such as the learners first language, age, and the context (classroom or natural setting).Implications:Errors are developmental and are a natural byproduct of learning tolerate them.Allow learners to make errors and do not correct them (3) The Input Hypothesis cIt lai
32、ms a move along the developmental continuum by receiving comprehensible input. We acquire, only when we understand the structure that is “a little beyond” where we are nowComprehensible input is defined as L2 input just beyond the Learners current L2 competence, in terms of its syntactic complexity.
33、 If a learners current competence is i then comprehensible input is i+1. Input which is either too simple (i) or too complex (i+2/3/4) will not be useful for acquisition. (4) The affective filter hypothesisSLA is affected by factors like Motivation, Self-confidence, Anxiety and so on.Learners who su
34、ffer from anxiety or lack of motivation or negative attitude somehow switch off their comprehension mechanisms and so even if they are provided comprehensible input, they will not be able to process the input. Therefore a low affective filter is important.(5) Monitor hypothesisBoth language learners
35、 and native speakers typically try to correct any errors in what they have just said. This is referred to as monitoring. Krashen uses the term Monitoring (with a big M) to refer to the way the learner used learnt knowledge to improve utterances produced by means of acquired knowledge.26. language tr
36、ansferLanguage transfer is the influence resulting from the similarities and differences between the target language and any other language that has been previously( and perhaps imperfectly ) acquired.27. LAD (language acquisition device) The LAD is a system of principles that children are born with
37、 that helps them learn language, and accounts for the order in which children learn structures, and the mistakes they make as they learn.28. critical age period hypothesisIt claims that there a period when language acquisition can take place naturally and effortlessly, but after a certain age the br
38、ain is no longer able to process language input in this. Researchers differ over when the critical period comes to an end. 29. field independent vs. field independentLearners are different in the ways of receiving, conceptualizing, organizing, and recalling information.Field dependents operate holis
39、tically (i.e. they see the field as a whole),Whereas field independents operate analytically (i.e. they see the field in terms of its component parts).30. input vs. intake Input refers to the language learners are exposed to.It serves as the data which learners must use to determine the rules of the
40、 target language. However, not all available input is processed by the learner, either because some of it is not understood or because some of it is not attended to. That part of input that is processed, assimilated and fed into the interlanguage system is referred to as intake.31.attitudes vs. apti
41、tude vs. intelligenceAttitudes refer to the learners beliefs about factors such as the target language culture, their own culture, their teacher and the learning tasks they are given.Aptitude refers to the specific ability a learner has for learning a second language.Intelligence refers to the gener
42、al ability to master academic skills.32. competence vs. performance When learners acquire a L2, they internalize rules which are then organized into a system. This constitutes their competence. The actual use of this system to comprehend and produce utterances is referred to as performance.33. Overg
43、eneralization It refers to the extension of some general rule to items not covered by this rule in the target language. 34. foreigner talk vs. teacher talk When native speakers address learners, they make adjustments in both language form and language function to facilitate understanding. These adju
44、stments are referred to as foreigner talk. When teachers address learners, they make adjustments in both language form and language function to facilitate understanding. These adjustments are referred to as foreigner talk.35. formulaic speech vs. patterns Formulaic speech consists of expressions whi
45、ch are learned as unanalysable wholes and employed in particular occasions. Patterns are one type of formulaic speech. They are unanalysable units which have one or more open slots, e.g. Can I have a 。36. interference According to the behaviorist learning theory, old habits get in the way of learnin
46、g new habits. Thus in SLA, the patterns of the learners mother tongue get in the way of learning the patterns of the L2. This is referred to as interference.37. order/sequence/route of development Order of development refers to the order in which specific grammatical features are acquired in SLA. Th
47、ese vary according to such factors as the learners L1 background and other factors. Sequence of development refers to the overall profile of development of SLA which is held to be universal and thus, not subject to variation as a result of L1 background and other factors. Route of development refers
48、 to those transitional states the learners have to go through in the process of SLA. It is intended to be neutral regarding whether it is universal or subject to variation.38. Universal Hypothesis The universal hypothesis states that language acquisition is governed by the way in which natural languages are organized. That is, certai
