MEISEL INTRODUCTION: FUNCTIONAL CATEGORIES AND VERB PLACEMENT IN LANGUAGE DEVELOPMENT 1. UG AND FUNCTIONAL CATEGORIES Research investigating the development of early linguistic knowledge has been stimulated enonnously, during the past decade, by recent versions of Generative Grammar. The Principles-and-Parameters framework of the theory of Universal Grammar (UG), as developed by Chomsky (1981) and others, has proved to be particularly useful for studies dealing with grammatical development. It allows for the fonnulation of more specific hypotheses than were possible in earlier models about what will be constant and what may be expected to vary in the course of language acquisition or of language change in history; see the papers in Roeper and Williams (eds.) (1987) and, more recently, the work by Lightfoot (1991) for examples illustrating this point. UG is understood in this approach as a crucial component of the language acquisition device. This implies, most importantly, that a developing grammatical system, at each stage of the process of change, only contains structures and mechanisms which do not violate the principles of UG. In other words, the relevance of grammatical theory for language acquisition studies - and vice versa - depends on the continuity assumption (Pinker, 1984; see also White 1982). As Pinker (1984:7) states, "in the absence of compelling evidence to the contrary, the child's grammatical rules should be drawn from the same basic rule types, and be composed of primitive symbols from the same class, as the grammatical rules attributed to adults in standard linguistic investigations." Note that, contrary to what one might suspect. assuming continuity does not necessarily commit one to claiming that grammatical principles govern child language from the moment when the child utters the first comprehensible word. Rather, it allows for the possibility that there exists a "pregrammatical phase". Take. Jiirgen M.

MEISEL for example Bickerton's (1990a, 1990b) view, which represents perhaps the strongest claims of this sort. He calls this early language use "protolanguage" and argues (1990b:7) that "[ ... ] the child, up until time x, is simply learning words and their associations, and beginning to string these words together without any grammatical system whatsoever; in other words, a child under two is doing pretty much the kinds of thing that 'language' trained apes learn to do [. .. J". Sometime between ages 2;0 and 2;6, he contends, grammar comes in abruptly and rapidly as a consequence of brain maturation. As radical as such an approach may first appear to be, it is easily reconciled with the continuity assumption. What matters is that both models maintain that there is no stage of linguistic development during which the child uses a kind of grammatical system different in nature from the mature grammar. If children's grammars are indeed composed of symbols, structures, and rules of the same nature as those of adults, one wonders how to account for the obvious differences between child and adult language. To a certain extent, these may have to be explained as due to restrictions on immature cognitive or processing systems. The present discussion, however, is focused on the role of grammar. And this is where the distinction which is made in grammatical theory between phenomena related to non parameterized universal principles and those that depend on parameters of UG or on language-specific properties of grammar becomes relevant. Only in the case of non-parameterized principles will the continuity assumption predict that they are invariably present in child as well as in adult grammars. Concerning phenomena that depend on language-specific properties, UG and the continuity assumption quite obviously have nothing to say. Thus, the most interesting properties of grammar, from an acquisitional perspective, are clearly the parameterized principles of UG, for children need to find out how the values of the parameters are set in the language(s) they are acquiring. Since UG allows for different solutions in these cases, one can, in fact, expect children to explore the range of varia tion defined by parameterized options of UG, precisely because these choices are not detennined a priori but have to be made on the basis of in fonnation available in the input. If Borer (1984) and Chomsky (1989) are correct. parameters relate primarily to the non-substantive elements of the lexicon, that is, functional elements like INFL, COMP, DET, and so forth. It should therefore be particularly fascinating to study the development of this type of category and also the effect such development may have on INTRODUCTION 3 other aspects of developing grammars. And this is, indeed, what the contributions to this volume do. Parameterization of functional categories may, however, be understood in different ways, even if one shares the dual assumptions that substantive elements (verbs, nouns, etc.) are present in all grammars and that X-bar principles are part of the grammatical knowledge available to the child prior to language-specific learning processes. From these assumptions it follows that the child should, from early on, be able to construct projections on the basis of these elements. The role of functional categories, however, may still be interpreted differently. One possibility, first suggested by Radford (1986, 1990) and by Guilfoyle and Noonan (1988), is that children must discover which functional categories (FC) need to be implemented in the grammar of the language they are acquiring. Another possibility, first explored by Hyams (1986), is that a specific category is present in developing grammars but that parameter values are set in a way deviating from the target adult grammar, corresponding, however, to options realized in other adult systems. A third option would be that these categories might be specified differently in developing as opposed to mature grammars. All three are explored in the papers collected in this volume. Before outlining the various hypotheses in more detail, however, I would like briefly to sketch the grammatical context in which the following debate is situated. 2. I PAN D C PIN MAT U REG RAM MAR S The discussions in the present volume are concerned mainly with the categories C (or COMP) and I (or INFL) and their projections, since these are the ones which may host moved elements (finite verbs, subjects, topicalized constituents, as the like). In earlier versions of generative grammar, all the necessary information concerning tense, modality, and aspect (TMA), as well as information necessary for subject-verb agreement was contained in a category AUX. In more recent proposals, e.g. Chomsky (1986a), Rizzi (1987), and others, this was captured in the double-headedness of INFL. (1) INFL ~ (AGR) AUX 4 JORGEN M. MEISEL In (1), AGR contains the so-called phi-features, that is, features for person, number, and in some languages gender; see Chomsky (1982). AUX contains at least tense (TNS or T), probably also aspect and modality. More recently still, Pollock (1989), Chomsky (1989), and others developed the so-called "split-INFL hypothesis", and in this hypothesis AGR is regarded as an independent category, sometimes even as two different categories, AGRs and AG~, referring to subject and object agreement, respectively; see Chomsky (1989). T is either viewed as being contained in INFL, or as representing another independent category. Some authors, however, sug gest a category F (Finiteness), assuming that tensed clauses may be regarded as finite entities. Note that, according to X-bar theory, each of these categories heads its own maximal projection. Little has been said in recent publications about modality and aspect. What is important in the present context is that the "sentence" has disappeared as a basic notion of grammar. Instead, sentences are now understood as VPs (verb phrases) dominated by projections of the functional categories INFL, AGR, COMP, and so forth. As a result, a simple sentence structure, adhering to the more "conservative" version containing IP and AgrP only, would look like (2) for SVO languages like English or like (3) for SOY languages like German.
