摘要：This Forum challenges the generally accepted position in the linguistic sciences -- conscious or not -- that monolingualism and nativeness are essentially synonymous in an exclusive way. We discuss two consequences of our position that naturalistic bilinguals and multilinguals exposed to a language in early childhood are also native speakers: (i) that bi-/multilinguals have multiple native languages; and (ii) nativeness can be applicable to a state of linguistic knowledge that is characterized by significant differences to the monolingual baseline.

摘要：This study presents an investigation of oral narratives collected from heritage Egyptian and Palestinian Arabic speakers living in the United States. The focus is on a number of syntactic and morphological features in their production, such as word order, use of null subjects, selection of prepositions, agreement, and possession. The degree of codeswitching in their narratives was also investigated. The goal was to gain some insights into the Arabic linguistic competence of this group of speakers. The results show that although Arabic heritage speakers display significant competence in their heritage colloquial varieties, there are gaps in that knowledge. There also seems to be significant transfer from English, their dominant language. Adapted from the source document

摘要：Although claims about explicit and implicit language knowledge are central to many debates in SLA, little research has been dedicated to measuring the two knowledge types (R. Ellis, 2004, 2005). The purpose of this study was to validate the use of the battery of tests reported in Ellis (2005) to measure implicit and explicit language knowledge. Whereas Ellis (2005) tested only second-language (L2) learners (of English), this study tested both L2 and heritage language (HL) learners (of Spanish). Results showed that test scores loaded on a two-factor model, as in Ellis (2005), thereby providing construct validity for the tests, on a population of HL learners who have little explicit knowledge by virtue of the environment in which they acquired Spanish.

摘要：This special issue of Studies in Second Language Acquisition, which is devoted to the linguistic knowledge of heritage language speakers, is introduced. Heritage languages are defined as ethnic minority languages from around the world. In North America, Europe, and Australia, at least two types of heritage languages are found -- indigenous languages of a group of speakers who have always inhabited the region where the majority language is spoken and languages of immigrants who move into a country where the majority language is now spoken.

摘要：Morphological variability and the source of these errors have been intensely debated in SLA. A recurrent finding is that postpuberty second language (L2) learners often omit or use the wrong affix for nominal and verbal inflections in oral production but less so in written tasks. According to the missing surface inflection hypothesis, L2 learners have intact functional projections, but errors stem from problems during production only (a mapping or processing deficit). This article shows that morphological variability is also characteristic of heritage speakers (early bilinguals of ethnic minority languages) who were exposed to the family language naturalistically in early childhood but failed to acquire age-appropriate linguistic competence in the language. However, because errors in heritage speakers are more frequent in written than in oral tasks, the missing surface inflection hypothesis does not apply to them. The discussion considers how morphological errors in the two populations seem to be related to the type of experience. Adapted from the source document

摘要：It is widely recognized that the processor has a key role to play in creating and strengthening the mapping between form and meaning that is integral to language use. Adopting an emergentist approach to heritage language acquisition, the current study considers the extent to which the operation of the processor can contribute to an account of what is acquired, what is subsequently retained or lost, and what is never acquired in the first place. These questions are explored from two perspectives. First, morphosyntactic phenomena for which there is apparently substantial input are considered, with a focus on the relevance of salience, frequency, and transparency to the establishment of form-meaning mappings. Second, a phenomenon for which there appears to be relatively little input (i.e., scope) is examined with a view to understanding its fate in heritage language acquisition. In both cases, the emergentist perspective appears to offer promising insights into why heritage language learners succeed-and fail-in the way that they do. Adapted from the source document

摘要：This study presents and analyzes the comprehension of relative clauses in child and adult speakers of Russian, comparing monolingual controls with Russian heritage speakers (HSs) who are English-dominant. Monolingual and bilingual children demonstrate full adultlike mastery of relative clauses. Adult HSs, however, are significantly different from the monolingual adult controls and from the child HS group. This divergent performance indicates that the adult heritage grammar is not a product of the fossilization of child language. Instead, it suggests that forms existing in the baseline undergo gradual attrition over the life span of a HS. This result is consistent with observations on narrative structure in child and adult HSs (Polinsky, 2008b). Evidence from word order facts suggests that relative clause reanalysis in adult HSs cannot be attributed to transfer from English. Adapted from the source document

摘要：In response to new theoretical claims and inconclusive empirical findings regarding relative clauses in East Asian languages, this study examined the factors relevant to relative clause production by Korean heritage speakers. Gap position (subject vs. object), animacy (+/- animate), and the topicality of head nouns (+/- topicalization) were manipulated as experimental variables, and factors that appear to have been confounded in previous studies (e.g., context, proficiency) were controlled for or measured. Data were collected from Korean native and heritage speakers using an elicited production task. Group results failed to show a subject advantage, but individual analysis revealed that the effect of gap position varied for speakers at different levels of Korean proficiency. Results from the topicalized lead-in condition as well as error analysis revealed two different sources related to these patterns: Traditional asymmetry (i.e., subject advantage) appears to reflect the noun phrase accessibility hierarchy effect, whereas backward asymmetry (i.e., object advantage) seems to stem from word order strategy. Proficiency scores exhibited a modest correlation with the different individual response patterns. However, an animacy effect was not observed. The implications of these findings are discussed in terms of a general learning strategy, language universals based on informational prominence, the role of proficiency, and the effect of task demands.

摘要：This investigation intends to assess the effectiveness of a lexical recognition test (Meara & Buxton, 1987) as a placement tool that distinguishes among levels of two groups of students: Spanish heritage language learners (HLL) and second language learners (SLL). Three hundred and thirty university students from four different levels completed a 10-minute/200-word task based on Davies' (2006) Spanish frequency corpora. The results were compared to those from a control group of bilingual graduate students. As comparison measures, about half of the students completed a Cloze Test while the rest were asked to carry out a Multiple-task Test. The results of the study suggest that for SLL, and HLL at the lower levels of language ability, a lexical test based on the 5000 most frequent words in Spanish is a valid and practical testing tool that correlates with other measures of language proficiency. For more advanced levels of HLL, a wider range of words is necessary to avoid the ceiling effect. [Reprinted by permission of Sage Publications, Ltd., copyright holder.]

摘要：This review presents a broad picture of recent work on L2 Spanish in educational contexts. The thematic and geographic scope of the review is wide, in order to capture the diversity of learners and learning contexts of L2 Spanish, just two decades after teaching and learning the language gained impetus worldwide. Traditional second or foreign language learners, heritage learners, immigrants and indigenous children provide a variety of contexts for research that builds on and expands the fields of second and foreign language learning and teaching, applied linguistics and sociolinguistics. Continuing the trend from previous years in SLA, and in connection with research on learners of other languages, main themes in this time period have been the acquisition and teaching of the language system, learning processes, and social contexts of learning. The review is organized thematically according to these main categories. Adapted from the source document

摘要：Using data from a multisited ethnography of Ecuadorian transnational musicians, I applied Lave and Wenger's (1991) concept of legitimate peripheral participation and Jacoby and Ochs's (1995) notion of co-construction to examine two musicians attempts to learn Quichua, an Ecuadorian indigenous language. Through an analysis aided by constructivist grounded theory (Charmaz, 2006), I found that co-constructed notions of language beliefs, ethnic identity, and community perspectives led to perceptions of these individuals as legitimate or nonlegitimate learners of Quichua. These co-constructions played a role in a successful acquisition of Quichua for one individual, for whom Quichua was a heritage language, and a failure to succeed by the other. The results of this article enrich discussions on maintenance of threatened languages and add to the ongoing debate in second language acquisition on the importance of cognitive/individual versus social/external factors in language learning.

摘要：This article draws on data from an ethnographic multiple-case study on the identity, positioning, and interactions of Spanish as a heritage language (SHL) students in regular Canadian high school Spanish classes. Interview and classroom observational data are discursively analyzed to reveal the presence of a form of language ideology that equates displayed Spanish speaking ability with language proficiency and heritage. This type of language ideology particularly impacted how one SHL student, who was reluctant to speak Spanish, was positioned and treated in class in ways that not only did not acknowledge her Hispanic heritage or encourage the development of her oral skills, but also did not recognize the usefulness of her literacy skills. This article problematizes the assumptions that HL students are typically able (and willing) to speak their HL and that this ability is viewed as their most important asset in class. The article concludes with pedagogical implications and directions for future research. Adapted from the source document

摘要：In contrast with the field of second language acquisition (SLA), where until recently sociocultural concerns were largely unaddressed (Block, 2007), identity has always been at the core of heritage language (HL) education. The present article highlights this often overlooked history and presents action research centering on a Spanish critical service-learning program stressing identity and social activism in HL education. The article begins with an examination of the constructs of identity, agency, and advocacy in Spanish HL education and critical pedagogy. Stressing that critical pedagogy seeks not only to promote agency but also to contribute to social justice outside of the classroom, we provide an overview of our critical service-learning program melding university HL education with community language activism. The program builds upon HL speakers' classroom-based learning of critical language awareness by providing community-based opportunities to enact and strengthen identities as language experts and to contribute to positive social change. Next, we present and analyze qualitative data gathered in order to investigate the emergence of expert and activist identities among program participants who worked to counteract school-based subordination of Spanish by running an after-school Spanish class for HL speakers at a local elementary school.
