It shows that heritage speakers are a highly heterogeneous population from both a psycholinguistic and sociolinguistic point of view. In principle, their language can differ from the language of their input (baseline language, usually that of first-generation immigrants to a new country). The differences can be due to how the heritage language developed under reduced input conditions, interference from the dominant language (transfer) and innovations in the grammar, potential changes incipient in the input, and attrition proper. The latter is particularly apparent when the language of adult heritage speakers is compared with the language of bilingual children; such children outperform heritage speakers on a variety of linguistic properties. The critical factors that affect language change in heritage speakers include the age of onset of bilingualism and quantity/quality of input.","PeriodicalId":396604,"journal":{"name":"The Oxford Handbook of Language Attrition","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126056097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adopting Putnam & Sánchez’s (2013) position which associates incomplete acquisition and language attrition with the increased lack of activation of the recessive first language (L1) over the course of the lifespan, we demonstrate here the potential to integrate these ideas with the FRH into a unified model. This chapter concludes with a discussion of how the core ideas can be extended to research beyond the traditional generative paradigm, including an extension to probabilistic models of linguistic analysis.","PeriodicalId":396604,"journal":{"name":"The Oxford Handbook of Language Attrition","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121873636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Early researchers took an explorative stance to examine what happened to the L2 of Japanese returnees once they had left the L2 milieu. Then researchers shifted their focus towards testing various hypotheses including the regression and retrieval failure hypotheses. Since 2010, a new focus has been given to researching different language areas such as indefinite/definite articles, and story-telling skills. The exploratory data has been further diversified from spontaneous oral and written data to brain-imaging data. The overall findings in attrition research in Japan examining the language loss of Japanese returnees are chronologically detailed, along with how the research focus has shifted using different methods of data collection.","PeriodicalId":396604,"journal":{"name":"The Oxford Handbook of Language Attrition","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127789019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two main directions in accounting for differential susceptibility of morphemes to attrition are identified: a) focus on inherent properties of morphemes; and b) focus on mechanisms underlying morphological processing. The chapter concludes by considering challenges faced by morphological studies, including lack of consistency in types of informants, data, and data collection techniques, and limitations of the available theoretical approaches for the analysis of the complexity and variety of morphological operations and morphemes that become restructured, modified, and ultimately lost in the course of L1 attrition.","PeriodicalId":396604,"journal":{"name":"The Oxford Handbook of Language Attrition","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134508406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This chapter presents an overview of the most frequently used method of operationalizing language experience in bilingual language acquisition research, namely the parental questionnaire.

The hypothesis compares different degrees of success/difficulty in the acquisition of syntax, semantics, and morphology. Its main tenets are that functional morphology presents the biggest challenge to acquisition, while syntax and semantics are relatively easier to acquire because they employ universal operations. The grammars of early and late attriters are examined to check these expectations. An overview of the literature suggests that early attriters are indeed challenged by inflectional morphology, especially when expressed by large paradigms and when lexical learning of affixes is involved. However, early attriters rarely have issues with basic syntax. Essentially the same picture emerges for late attriters, modulated by linguistic complexity, redundancy of the marker, opaqueness of form–meaning mapping, and usage frequency. While the Bottleneck Hypothesis is too large-grained to explain all findings, its predictions appear to be largely borne out.","PeriodicalId":396604,"journal":{"name":"The Oxford Handbook of Language Attrition","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114845396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this introductory chapter, we first of all sketch how psycholinguistic and neurolinguistic insights have very quickly become a pillar of attrition research. To do this, this introduction explores language attrition as a processing, memory, and brain mechanism before turning to an outline of the contributions in this section.
