Amnesia and second language learning

The ability of an anterograde amnesic C.S. to learn a second language is assessed. First, her claim that she learned Italian while amnesic was examined in a series of formal tests of Italian. Second, C.S. and her husband were tutored in French and her acquisition was compared to that of her husband's. Third, C.S.'s ability to learn other kinds of verbal material with practice was investigated. The implications of C.S.'s apparent ability to learn a second language in the presence of a severe deficit for memory for other kinds of verbal material is discussed.     

Language transfer and blocking in second language vocabulary learning

The influence of different vocabulary instructional techniques upon the acquisition of different language words was examined in two experiments. In Experiment 1, comparisons were made between the learning of Chinese and French words employing both paired-associate presentations and spacing procedures. The results supported the view that language transfer affects the acquisition of second language words, with more French words being learned than Chinese words. The superiority of the spacing procedure over the paired-associate presentation found in these results suggested that the spacing method diminished the adverse effects of blocking and thus enhanced learning. However, no significant interaction between the teaching procedures and different language words was detected. That is, under the spacing procedure, greater improvement in learning of Chinese words was not found. The experiment was thus modified by substituting the spacing procedure with aural feedback in Experiment 2. In this experiment, a significant interaction between these two factors was detected. That is, the recall for French was more than Chinese in the paired-associate condition, however, under the aural feedback, performance in Chinese was statistically equivalent to that in French. Hence, these findings may contradict the prediction of language transfer. It appears that the phenomenon of language transfer may be far less important in vocabulary learning than the use of a method of instruction which neutralises the negative effects of blocking.     

Functional connectivity changes in second language vocabulary learning

Functional connectivity changes in the language network (Price, 2010), and in a control network involved in second language (L2) processing (Abutalebi & Green, 2007) were examined in a group of Persian (L1) speakers learning French (L2) words. Measures of network integration that characterize the global integrative state of a network (Marrelec, Bellec et al., 2008) were gathered, in the shallow and consolidation phases of L2 vocabulary learning. Functional connectivity remained unchanged across learning phases for L1, whereas total, between- and within-network integration levels decreased as proficiency for L2 increased.The results of this study provide the first functional connectivity evidence regarding the dynamic role of the language processing and cognitive control networks in L2 learning (Abutalebi et al., 2005, Altarriba and Heredia, 2008, Leonard et al., 2011, Parker-Jones et al., 2011). Thus, increased proficiency results in a higher degree of automaticity and lower cognitive effort (Segalowitz & Hulstijn, 2005).     

Primary or "specific" language impairment and children learning a second language

We review empirical findings from children with primary or "specific" language impairment (PLI) and children who learn a single language from birth (L1) and a second language (L2) beginning in childhood. The PLI profile is presented in terms of both language and nonlinguistic features. The discussion of L2 learners emphasizes variable patterns of growth and skill distribution in L1 and L2 which complicate the identification of PLI in linguistically diverse learners. We then introduce our research program, designed to map out common ground and potential fault lines between typically developing children learning one or two languages, as compared to children with PLI.     

Fostering learning from instructional video in a second language

This study investigated the most effective way to present an instructional video that contains words in the students' second language. Korean‐speaking university students received a 16‐min video lesson on Antarctica that included English narration (video + narration group), English text subtitles (video + text group), or English narration with simultaneous text subtitles (video + narration + text group). On a comprehension test, the video + text group scored higher than each of the other two groups, in contrast to the modality effect; and the video + narration + text group outscored the video + narration group, in contrast to the redundancy effect. Each of the lessons that included text was rated as less difficult than the lesson with narration only. The narration + text group reported lower effort than each of the other groups. Results highlight boundary conditions for two principles of multimedia instructional design that apply for college students who are learning in a second language. Theoretical implications are discussed.     

Emergent verbal behavior in preschool children learning a second language

We evaluated the emergence of untaught second‐language skills following directly taught listener and intraverbal responses. Three preschool children were taught first‐language (English) listener responses (e.g., “Point to the horse”) and second‐language (Welsh) intraverbal responses (e.g., “What is horse in Welsh?” [ceffyl]). After intervention, increases in untaught second‐language tacts (e.g., “What is this in Welsh?” [ceffyl]) and listener responses (e.g., “Point to the ceffyl”) were observed for all 3 participants.     

The effect of aural feedback in second language vocabulary learning

We examined instructional procedures in the teaching of second language vocabulary, using a paired-associate paradigm. Four presentation methods were investigated, including simultaneous standard, simultaneous reversal, aural feedback, and visual feedback. The study involved 16 grade 7 school children as subjects. Subjects were tested on 28 second language words during the post-test stage. Orthogonal comparisons were carried out for the obtained data. The two feedback conditions proved to be the most beneficial and the more favourable out of these was the aural feedback condition. Also, reversing the two inputs proved to be better than the conventional paired-associate (e.g. presenting the second language word first with the first language word second). Based on the results of this study, it is advocated that the feedback procedures, in particular, be used in second language learning with aural feedback replacing visual feedback.     

Multiple goals, writing strategies, and written outcomes for college students learning English as a second language

This study examined relations of achievement goals of writers who are speakers of English as a foreign language (EFL), the frequency of their writing strategy use, and the quality of their writing from a multiple goals perspective. The goal profiles of 57 EFL college students with similar writing proficiency were based on rating items of an unpublished scale; Group 1 had strong mastery and strong performance-approach goals, and two groups included students with only one strong mastery (Group 2) or performance (Group 3) goal. Think-aloud protocols indicated that the participants adopted 21 strategies in an argumentative writing task, classified into five categories. Group 1 was found to use writing strategies of monitoring or evaluating, revising, and compensating significantly more often than the other two groups, and produced better essays. Strong mastery and performance-approach goals might be beneficial for EFL college writers.     

Language,cognition, and second language grammaticality judgments

In first language research, there appear to be two predominant positions relating metalinguistic awareness to language development. One suggests that since metalinguistic awareness is related to primary language acquisition (comprehension and production), general cognitive processes perform a limited role in metalinguistic awareness. The other suggests that since metalinguistic awareness is more closely related to secondary language acquisition (reading and writing), a greater role is assumed by general cognitive processes. There have been some indirect attempts to study the role of language and cognition with respect to second language grammaticality judgments. There is growing evidence that metalinguistic awareness is a reliable indicator of developing second language competence. Furthermore, it has been shown that language aptitude is significantly related to metalinguistic awareness. The present study was designed to investigate the statistical relationship between second language grammaticality judgments and selected cognitive and linguistic variables. The variables studied were second language proficiency, second language classroom achievement, first language reading competence, language aptitude, nonverbal intelligence, field dependence-independence, and a written grammaticality judgment test tapping the ability to recognize, and correct, deviance. Subjects were college students in advanced English-as-a-second-language classes. Multivariate statistical techniques were used to determine the relative contribution of linguistic and cognitive variables to the individual variation demonstrated by the learners in their ability to detect deviance in English. The results showed that second language proficiency, second language achievement in the classroom, and language aptitude were significant predictors of the subjects' ability to make grammaticality judgments. First language reading competence was significantly related to subjects' ability to correct deviance. These observations are discussed in the light of: (1) the relationship among cognition, language, and metalinguistic awareness, and (2) the role of metalinguistic awareness in second language acquisition and second language learning.     

Critical period effects in second language learning: the influence of maturational state on the acquisition of English as a second language

Lenneberg (1967) hypothesized that language could be acquired only within a critical period, extending from early infancy until puberty. In its basic form, the critical period hypothesis need only have consequences for first language acquisition. Nevertheless, it is essential to our understanding of the nature of the hypothesized critical period to determine whether or not it extends as well to second language acquisition. If so, it should be the case that young children are better second language learners than adults and should consequently reach higher levels of final proficiency in the second language. This prediction was tested by comparing the English proficiency attained by 46 native Korean or Chinese speakers who had arrived in the United States between the ages of 3 and 39, and who had lived in the United States between 3 and 26 years by the time of testing. These subjects were tested on a wide variety of structures of English grammar, using a grammaticality judgment task. Both correlational and t-test analyses demonstrated a clear and strong advantage for earlier arrivals over the later arrivals. Test performance was linearly related to age of arrival up to puberty; after puberty, performance was low but highly variable and unrelated to age of arrival. This age effect was shown not to be an inadvertent result of differences in amount of experience with English, motivation, self-consciousness, or American identification. The effect also appeared on every grammatical structure tested, although the structures varied markedly in the degree to which they were well mastered by later learners. The results support the conclusion that a critical period for language acquisition extends its effects to second language acquisition.     

Infant artificial language learning and language acquisition

The rapidity with which children acquire language is one of the mysteries of human cognition. A view held widely for the past 30 years is that children master language by means of a language-specific learning device. An earlier proposal, which has generated renewed interest, is that children make use of domain-general, associative learning mechanisms. However, our current lack of knowledge of the actual learning mechanisms involved during infancy makes it difficult to determine the relative contributions of innate and acquired knowledge. A recent approach to studying this problem exposes infants to artificial languages and assesses the resulting learning. In this article, we review studies using this paradigm that have led to a number of exciting discoveries regarding the learning mechanisms available during infancy. These studies raise important issues with respect to whether such mechanisms are general or specific to language, the extent to which they reflect statistical learning versus symbol manipulation, and the extent to which such mechanisms change with development. The fine-grained characterizations of infant learning mechanisms that this approach permits should result in a better understanding of the relative contributions of, and the dynamic between, innate and learned factors in language acquisition.     

Neural aspects of second language representation and language control

A basic issue in the neurosciences of language is whether an L2 can be processed through the same neural mechanism underlying L1 acquisition and processing. In the present paper I review data from functional neuroimaging studies focusing on grammatical and lexico-semantic processing in bilinguals. The available evidence indicates that the L2 seems to be acquired through the same neural structures responsible for L1 acquisition. This fact is also observed for grammar acquisition in late L2 learners contrary to what one may expect from critical period accounts. However, neural differences for an L2 may be observed, in terms of more extended activity of the neural system mediating L1 processing. These differences may disappear once a more 'native-like' proficiency is established, reflecting a change in language processing mechanisms: from controlled processing for a weak L2 system (i.e., a less proficient L2) to more automatic processing. The neuroimaging data reviewed in this paper also support the notion that language control is a crucial aspect specific to the bilingual language system. The activity of brain areas related to cognitive control during the processing of a 'weak' L2 may reflect competition and conflict between languages which may be resolved with the intervention of these areas.     

Philosophy and language learning

In this paper, I explore different ways of picturing language learning in philosophy, all of them inspired by Wittgenstein and all of them concerned about scepticism of meaning. I start by outlining the two pictures of children and language learning that emerge from Kripke’s famous reading of Wittgenstein. Next, I explore how social-pragmatic readings, represented by Meredith Williams, attempt to answer the sceptical anxieties. Finally, drawing somewhat on Stanley Cavell, I try to resolve these issues by investigating what characteristically happens to our view of language learning when we do philosophy. The focus throughout is on the relation between the individual (the learning child) and the community (usually represented by the parents), and how that relation is deformed when we operate with a certain philosophical notion of ground.     

Working memory and second language accent acquisition

We explored the proposal that overt repetition of verbal information improves the acquisition of a native accent in a second language. Mandarin‐speaking Chinese learners of English were recorded while repeating and reading out English sentences before and after one of three treatments: (a) repeating native English sentences subvocally, “covert repetition,” (b) repeating sentences out loud, “overt repetition,” and (c) unfilled time of comparable duration. The sentences were rated by English speakers for their nativeness, fluency, and intelligibility. Overt repetition improved accent rating for readout sentences. Covert repetition did not. Neither condition improved accent rating for repeated sentences, suggesting that immediate repetition depends on temporary rather than long‐term representations. Our results provide some support for the use of overt repetition in accent learning. From a theoretical perspective, an interpretation is proposed in terms of a separation between phonological and articulatory coding within the phonological loop component of working memory.     

语音短时记忆与词汇知识对第二语言词汇学习的影响

选取两种语音熟悉程度不同的非词为实验材料,把语音短时记忆区分为项目短时记忆和序列短时记忆,考察语音短时记忆与词汇知识对汉英双语者第二语言（英语）词汇学习的影响。实验1采用产出性的方式进行学习,结果发现,词汇知识与项目短时记忆对语音熟悉非词的学习起预测作用;词汇知识与序列短时记忆对语音不熟悉非词学习起预测作用。实验2采用接受性的方式进行学习,结果发现,项目短时记忆、序列短时记忆和词汇知识都对语音熟悉非词学习起独立的预测作用;项目短时记忆和序列短时记忆对语音不熟悉非词学习起独立的预测作用。实验结果表明,语音短时记忆和词汇知识都是影响英语词汇学习的重要因素。具体而言,学习语音熟悉的词汇,词汇知识起着更为重要的作用;学习语音不熟悉的词汇,语音短时记忆、特别是序列短时记忆起着更为重要的作用,而且两者作用的大小随着词汇学习方式的不同而发生变化。
