A SUBJECT-OBJECT ASYMMETRY IN THE ACQUISITION OF RELATIVE CLAUSES IN KOREAN AS A SECOND LANGUAGE

A variety of studies have reported that learners of English as a second language find subject relative clauses easier to produce and comprehend than direct object relatives, but it is unclear whether this preference should be attributed to structural factors or to a linear distance effect. This paper seeks to resolve this issue and to extend our understanding of SLA in general by investigating the interpretation of subject and direct object relative clauses by English-speaking learners of Korean, a left-branching language in which subject gaps in relative clauses are more distant from the head than are object gaps. The results of a comprehension task conducted with 53 beginning and intermediate learners point toward a strong preference for subject relative clauses, favoring the structural account.

The Syntax of Idioms

This paper proposes that idioms are subject to the Continuity Constraint, a grammatical principle that defines their general architecture in terms of a chain of head-to-head relations. The Continuity Constraint accurately describes the organization of extant idioms, including non-constituent idioms, while at the same time correctly predicting that certain types of patterns are impossible. In addition, it sheds new light on the relevance of argument structure to idiom creation, uncovering asymmetries in the composition of idioms that appear to involve thematic hierarchy effects.

AN EMERGENTIST PERSPECTIVE ON HERITAGE LANGUAGE ACQUISITION

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.

TOWARD A NEW NATIVISM

The field of language acquisition is divided over the question of whether the inborn mechanisms underlying linguistic development include actual grammatical categories and principles or are of a more general character. Recent proposals suggest a possible convergence of views on this matter, with implications for the study of both first language acquisition and second language learning. This paper explores this possibility by examining the evolution of grammatical nativism with particular emphasis on a radical shift in the generality of the inborn principles that have been posited in recent work. The nature and implications of this shift are illustrated with the help of developmental data involving gap-containing structures in first and second language acquisition.

A Mapping Theory of Agrammatic Comprehension Deficits.

This paper offers evidence for the Isomorphic Mapping Hypothesis, which holds that individuals with agrammatic aphasia tend to have difficulty comprehending sentences in which the order of NPs is not aligned with the structure of the corresponding event. We begin by identifying a set of constructions in English and Korean for which the IMH makes predictions distinct from those of canonical order and trace-based theories of agrammatic comprehension. Then, drawing on data involving the interpretation of those patterns by English-speaking and Korean-speaking agrammatics, we argue for the conceptual and empirical superiority of the isomorphic mapping account.

The transition from optional to required subjects.

We propose (contra Hyams, 1986) that the optional subject phenomenon in early child language arises because children have not yet acquired the morphological elements (primarily modals and tense) necessary to distinguish Subject-Taking (ST) verbs (e.g. finite verbs) from their non-Subject-Taking (NST) counterparts (e.g. infinitives). Unaware of this distinction, children are able only to observe that verbs sometimes occur with subjects and sometimes without. We show that our proposal makes a number of developmental predictions which we then test with the help of longitudinal data from three children. We conclude that: (1) There is no systematic morphological distinction between ST and NST verbs during the optional subject stage (OSS). (2) The emergence of the distinction between ST and NST verbs is gradual rather than sudden. (3) There is variation from child to child in terms of which morphologically-defined subclass of verbs is first recognized as subject-taking. (4) There is no link between the emergence of modals or contracted copulas and the end of the OSS.

Directionality Preferences in the Interpretation of Anaphora: Data from Korean and Japanese.

Recent work by Lust and others has led to the prediction that children acquiring left-branching languages will exhibit a preference for backward patterns of anaphora. In this paper, we test this prediction against data from Korean and Japanese and show it to be false. An alternative hypothesis proposing a preference for forward patterns of anaphora is outlined and possible explanations for earlier experimental results supporting Lusts prediction are considered.

Asymmetries in children's production of relative clauses: data from English and Korean

We report here on a series of elicited production experiments that investigate the production of indirect object and oblique relative clauses by monolingual child learners of English and Korean. Taken together, the results from the two languages point toward a pair of robust asymmetries: children manifest a preference for subject relative clauses over indirect object relative clauses, and for direct object relative clauses over oblique relative clauses. We consider various possible explanations for these preferences, of which the most promising seems to involve the requirement that the referent of the head noun be easily construed as what the relative clause is about.

Language acquisition without an acquisition device

Most explanatory work on first and second language learning assumes the primacy of the acquisition phenomenon itself, and a good deal of work has been devoted to the search for an ‘acquisition device’ that is specific to humans, and perhaps even to language. I will consider the possibility that this strategy is misguided and that language acquisition is a secondary effect of processing amelioration: attempts by the processor to facilitate its own functioning by developing routines of particular sorts.

Three factors in the design and acquisition of language.

Recent advances in linguistic theory offer new proposals about the factors that are crucial to understanding the design and acquisition of language-the genetic endowment, experience, and principles not specific to the language faculty. Of particular interest is the third of these factors, whose importance is now widely recognized, raising questions about its character, its role in shaping the language faculty, and its impact on the future of linguistic research.
