10、rners Individual Differences Impacting on Second Language AcquisitionChapter 1Language aptitudeSome learners learn better than others .It is commonly assumed that there is such a thing as a special talent or aptitude for second language that some language learners possess to a greater extent than ot

11、hers, which is largely responsible for individual differences in second language learning. Learners with high language aptitude will learn second language more easily. In general, there are four factors in language aptitude. 1.1 Phonetic coding abilityIt refers to the ability to identify and remembe

12、r sounds. This ability is seen as related to the ability to spell and to handle sound-symbol relationships .Learners with phonemic coding ability can perform well in listening comprehension.1.2 Grammatical sensitivityIt is the ability to recognize the grammatical functions of words in sentences. Som

13、e learners who are good at analyzing long and difficult sentences often have grammatical sensitivity. 1.3 Inductive learning abilityIt is the ability to induce grammatical rules from language examples. If a learner has a strong inductive ability, he or she can identify patterns of correspondence and

14、 relationships involving form and meaning and easily generalize patterns from one sentence to another. This is, as we often say, drawing inferences about other cases from one instance.1.4 Rote learning abilityThis ability is related to vocabulary remembering. Good memory is quite important for secon

15、d language acquisition. Certainly, we need some techniques when memorizing words or expressions.The difference of language aptitude is one reason why some learners learn better than others. Generally, if a learner has higher language aptitude, he or she can do better than others in second language a

16、cquisition. Chapter2 PersonalityIn the eyes of many language teachers, the personality of their students constitutes a major factor contributing to success or failure in second language learning .In most cases, the open-minded character is more beneficial to second language acquisition. 2.1 Extrover

17、ted and introverted learnersAccording to skehan, extroverted learners learn best by talking and physically engaging the environment. They work best in classroom which allow time for discussion or working with group. Since they are action oriented, they do well with activities involving some type of

18、physical activity .Extroverted learners are outgoing and enthusiastic. They prefer a public role. Quite often, they talk more than listen. It is often suggested that an extroverted learner is especially well suited to second language learning. Relatively, they perform well in oral communication. Peo

19、ple with an outgoing personality may enjoy certain advantages .For example, they may became involved in more social interaction, attract more attention from their teachers, and be less inhibited when asked to display their proficiency. While introverted learners learn best through quiet, mental refl

20、ection. They tend to enjoy reading, lectures, and writing over oral work. Besides they are often uncomfortable in discussion groups and hesitate to speak up in class. 2.2 Self-esteemIt refers to the degree to which individuals feel confident and believe themselves to be significant people. Presumabl

21、y, learners with high self-esteem are less likely to feel threatened when communicating in a strange language or in an unfamiliar situation. They may also be more ready to risk making mistakes or projecting a reduced image of themselves. They are brave.2.3 AnxietyIt is commonly suggested that modera

22、te anxiety is benefit to second language acquisition .There is sufficient evidence to show that anxiety is an important factor in SLA. Anxiety includes facilitating anxiety and debilitating anxiety. The former motivates learners to complete the new learning task, prompting them to make extra efforts

23、 to overcome their feelings of anxiety. The latter cause the learner to feel the learning task in order to avoid the source of anxiety. Williams (1991) suggest that the distinction between these two types of anxiety may correspond to the intensify of anxiety, with a low-anxiety state having a facili

24、tating function and a high-anxiety state a debilitating effect. This is the reason why some students often with high-anxiety perform poorly in examination, though they perform quite well in daily studies. Usually, when we have high-anxiety, our minds are blank. Mid-degree anxiety can benefit L2 lear

25、ning by initiating learners motivation.2.4 Tolerance for ambiguityIt is found that learners with greater tolerance for ambiguity scored higher in tests of listening comprehension. If learners can tolerate uncertainty without feeling insecure or confused, they are less likely to feel overwhelmed by t

26、he large amounts of strange material they must face when learning a second language (p64 William little wood Naiman et al ) Dot the Is and cross the ts is necessary We study, but we also need the tolerance for ambiguity at times.Chapter 3 MotivationSLA research views motivation as a key factor in L2

27、 learning. The mast dominant work in second language acquisition studies of motivation has been done by Cardner. A person who has positive attitudes toward the target culture is considered well-motivated. In general, Cardners model of integrative and instrumental motivation precisely describes the p

28、articular features of motivation in SLA.3.1 Integrative motivationA learner with integrative motivation has a genuine interest in the second language community. He or she wants to learn their language in order to communicate with them more satisfactorily and to gain closer contact with them and thei

29、r culture. According to Skehan (1998), Integrative motivation may be defined as the desire to achieve proficiency in a new language in order to know about the culture and to be able to participate in the life of the community that speaks the language. It is found that integrative motivation generall

30、y accompanied higher scores on proficiency tests in a foreign language. Learners with integrative motivation are more active in class and are less likely to drop out.3.2 Instrumental motivationIt is referred to the desire to acquire a language as a means for attaining utilitarian goals such as getti

31、ng a job, furthering a career, reading or translating technical materials in a target language, etc. A learner with instrumental motivation is more interested in how the second language can be a useful instrument towards furthering other goals , such as gaining a necessary qualification or improving

32、 employment prospects . Studies indicate that providing learners with incentives (such as money) May also aid learning by increasing the time learners spend studying, but the effects may cease as soon as the reward stops.3.3 Resultative motivationIt is likely that the relationship between motivation

33、 and achievement is an interactive one. A high level of motivation does stimulate learning, but perceived success in achieving. Language goals can help to maintain existing motivation and even create new types. We can find that many students desire to learn second language increase with gains in sec

34、ond languages proficiency. If a student performed well in an examination, he or she will have high spirit. Then his desire or motivation to learn a language increases. This is resultative motivation.3.4 Intrinsic motivation.The notion of intrinsic motivation is an old one in psychology. It was devel

35、oped as an alternative to goal-directed theories of motivation that emphasize the role of extrinsic rewards and punishments Keller (1984)identifies interest as one of the main elements of motivation, defining it as a positive response to stimuli based on existing cognitive structures in such a way t

36、hat learners curiosity is aroused and sustained . Intrinsic is more beneficial to second language acquisition.Chapter 4 Learning strategiesLearning strategies are classified in different ways. The most popular classification divides learning strategies into meta-cognitive and social strategies. If y

37、ou come across a new word in your reading and feel its meaning is important and you must learn it, you are using a meta-cognitive strategy. If you look it up in a dictionary, you are using a cognitive. If you ask a roommate about, you are using a social strategy.4.1 Meta-cognitive strategies.Meta-co

38、gnitive strategies have to do with managing ones learning activities. For instance, a learner may preview a lesson before going to class or draw up a plan for learning over the weekend. Meta-cognitive strategies deal with pre-assessment and pre-planning, on-line planning and evaluation, and post-eva

39、luation of language learning activities. According to Chamot, the following items are included in the meta-cognitive strategies: advance organization, it is making a general but comprehensive preview of the concept or principle in anticipated learning activities. Directed attention, it is deciding i

40、n advance to attend to a learning task and to ignore irrelevant distracters. Selective attention, it is deciding in advance to attend to specific aspects of language input or situational details that will cue retention of language input. Advance preparation, self-monitoring, self-evaluation. Preview

41、ing before class to find the difficulties, reviewing or reflecting after class to reinforce, self-evaluating, making a plan, these are all meta-cognitive strategies.4.2 Cognitive strategiesThey are directory related to learning. For example, one may relate a new word to other words in memory or may

42、read it aloud several times, the cognitive strategies include: repetition, resourcing, directed physical response. translation grouping note-taking deduction recombinationimageryauditory key word contextualization elaboration transfer prediction. These strategies are involved in the process of learn

43、ing.4.3 Socialaffective strategies.They have to do with how are relates to others, e.g., seeking out opportunities to practice second language, asking the teacher for further comments on ones essay. Affective strategies serve to regulate emotions, motivation, and attitudes, e.g. strategies for reduc

44、tion of anxiety and for self-encouragement. Socialstrategies include the actions which learners choose to take in order to interact with other learners and with native speakers socialaffective strategies include cooperation and question for clarification. Cooperation refers to work with one or more

45、peers to obtain feedback, poop information, or model a language activity. Question for clarification, it means that you can ask a teacher for repetition, paraphrasing, explanation and so on, if you are not sure yet about a problem.Learners clearly differ enormously in their approach to l2 learning b

46、ut it is impossible to say which learning style works best. Quite possibly, it is learners who display flexibility, who are most successful, but there is no real evidence yet for such a conclusion. However, it has been suggested that language learners who use certain strategies perform better than t

47、hose who do not. Chapter 5 AgeResearch found supportive evidence that age can make great differences in the speed of learning .There is widely-held lay belief that younger second language learners generally do better than older learners. This is supported by the critical hypothesis, which states tha

48、t there is a period when language acquisition takes place naturally and effortlessly. This hypothesis has led to the assumption that by the age of 12 or 13 , people have passed the ideal period of successful second language learning .Some researchers suggest that this is the result of the lateralization of the language function in the left hemi-sphere of the brain . Lateralization refers to the specialization o
