Research conducted since Ronjat’s seminal work on bilingualism has led to a high degree of specialisa- tion and to the birth of different schools. The three main schools, i.e., generative, constructivist and functionalist, all collect empirical data, but often give diverging interpretations to one and the same database. The field is divided into three main domains according to type of participants studied: monolingual and bilingual (or multilin- gual) acquisition and impaired language (SLI, Down syndrome and others). Not surprisingly the first case studies were conducted on monolingual children speaking European languages such as English, French or German. More exotic languages are becoming increasingly popular subjects of study, however, and have a representa- tion in this volume as well. It is in monolingual acquisition that the three theoretical approaches are most at odds. Whilst the interpretation of data in the constructivist approach relies very much on input, the generative approach bases its conclusions on theoretical constructs, as can be seen in two of the chapters in the present volume: Parisse and Müller & Pillunat, which focus on the topic of subject realization. Re- searchers became interested in the question as to whether monolingual and bilingual acquisition was qualitatively comparable in the nineteen-eighties. Much subsequent research that has compared bilingual and monolingual language acquisition has been able to show that both types of language acquisition are driven by the same principles. Only relatively recently have scholars working on theoretical approaches to language acquisition become interested in the field of language impairment. The general con- sensus amongst researchers is that children with SLI or Down syndrome go through the same stages as their monolingual or bilingual peers. If a difference is found, it is largely quantitative; the language of children with impairment is primarily delayed. This remains a debatable point, however, and some authors have claimed that the de- velopment of, for example, children with Down syndrome differs in some respects from that of typically developing children: particularly in the areas of morphology and syntax (Fowler 1990). This is the background against which the research described in this book is set. The book primarily seeks to address the generative approach to language acquisition in the three main domains: monolingual, bilingual acquisition and impaired language. As noted above, constructivists and generativists do not agree on the interpretation of data. This volume includes one chapter that is written in the Introduction constructivist tradition in order to suggest that a dialogue between these two ap- proaches is worth pursuing. Such a dialogue will contribute to our better understand- ing of the fascinating world of language acquisition. The main purpose of this volume is to present original research from two differ- ent perspectives and to provide a basis for dialogue between researchers working in these diverging theoretical frameworks. The volume includes state-of-the-art research conducted mostly within the generative framework and reflects the diversity of meth- odological approaches and research interests that can be found in contemporary re- search work in the field. Many chapters in this volume address issues linked to the left periphery in various languages; some chapters are devoted to syntactic or morphologi- cal issues. We strongly believe that the result makes a contribution to our theoretical understanding of morpho-syntax, as well as contributing to the developing body of knowledge about language acquisition in different groups of learners. 1. Monolingual acquisition The four following chapters are devoted to monolingual first language acquisition in different languages (i.e., French, Norwegian, Spanish and Swiss German). The chapter by Parisse studies subject dislocations by young French-speaking children in the con- structivist tradition, more specifically in the usage-based theory of language acquisition (UTB) by Tomasello (2000, 2003). In Parisse’s approach, French is a non pro-drop language where the use of a cliticized subject personal pronoun is mandatory if there is no lexical subject. In the presence of the subject in the form of a noun phrase or lexical subject, the cliticized personal pronoun is compulsory. This is what is called disloca- tion, which can be left or right dislocation. Hence, it is possible to move the dislocated subject anywhere, in front of or after the verb, and to insert elements between subject and verb. It is well known that the use of optional strong personal pronouns is often found in oral language and to a lesser extent in written texts. This is very common in children’s language and Parisse raises the following questions: (1) does children’s production merely reflect the distributional patterns of oral adult language?; (2) does children’s production reflect a specific developmental path in early French? In order to test hypothesis (1), a corpus of conversation transcripts between a child and an adult in a standardized situation was used by Parisse: the Bath Corpus. Parisse argues that children’s use of subject dislocations does not fully reflect their input. A second corpus, the House corpus, was used to test whether the use of subject dislocations follows a developmental pattern (hypothesis 2). The performance changes according to increas- ing age in that older children use more dislocated subjects. One possible explanation offered by Parisse is that this development pattern is the result of a growing systematic use of subject pronouns in front of a verb. In order to test this claim, the proportion of verbs preceded by a pronoun was computed for both corpora. This proportion tends to increase with age, and it correlates significantly with the use of constructions with Introduction pronouns in the children represented in both corpora. As opposed to this, there is no similar significant correlation in the adults’ production. Parisse argues that the pro- duction of optional pronouns is more likely to be a consequence of an automatic pro- duction of pronouns in front of a verb and that the optional character of the pronoun is learned at later age. He also claims that children build these constructions differently from adults. His interpretation of the data differs substantially from the approach used in the following chapters. The remaining chapters in this section are written in the generative tradition. In fact, the chapter by Gordishevski and Schaeffer reports the results of a longitudi- nal study with naturalistic settings. In particular, they investigated structural (NOM, ACC, GEN), inherent (DAT, INSTR), and lexical (ACC/DAT/GEN/INSTR/PREP assigned by prepositions) Case in the spontaneous speech of three Russian children raised monolingually. Inspired by Hoekstra & Hyams (1995), the researchers argue that their finding can be explained assuming the underspecification of the Number head. The results show that in the singular the children score very high, around 90% correct uses on NOM, on structural ACC, and on structural GEN as well as singular inherent DAT. Inherent INSTR was used only twice by two of the children. Similarly, the singular lexical Cases in total are produced correctly in 90% of the required con- texts. In contrast, plural nouns show much lower success rates: 0% for structural ACC and for structural GEN but 14% for the lexical Cases. Plural inherent INSTR was used a few times by two children. Errors are found in around 40% of the cases and consist of substitution by NOM forms. The performance improves in all cases in the subsequent stage. Close examination of the children’s plural forms suggests that plural is not pro- ductive: (a) numbers of plural forms are extremely low; (b) most of the words used in plural represent pair-wise (‘hands’) or plural (‘fingers’) body parts, types of footwear and plural non-count nouns; (c) almost none of the plurals occur in their singular forms in the same transcripts. On the basis of these observations, Gordishevski and Schaeffer propose that the nominal Num head is initially underspecified, namely, it represents [-plural] only (cf. Müller 1994). They assume that in order to check Case features on N and D a “Case-chain” needs to be established. Following Hoekstra and Hyams (1995), Gordishevski and Schaeffer propose that in case of a plural N, an un- derspecified Num ([-plural]) breaks the Case-chain, because the N’s plural feature cannot be checked. This blocks Case feature checking, yielding default NOM forms in early Russian. When the noun is singular, underspecified Num does not break the Case-chain as it is [-plural], thus yielding forms correctly marked for Case. Chapter three by Westergaard argues for an analysis of verb-second (V2) word order which involves a split CP as suggested by (Rizzi 1997) on acquisition data from a dialect of Norwegian (Tromsø). Investigating three children, it is shown that, although verb movement (i.e., verb-second (V2) word order in non-subject-initial) is generally acquired early in declaratives, the children make certain errors in topicalisations and questions with respect to the position of pronominal subjects in negated utterances. More specifically, in the early files the children predominantly produce the Neg-S word
