The science of linguistic diversity.
Research at our top-ranked department spans syntax, semantics, phonology, language acquisition, computational linguistics, psycholinguistics and neurolinguistics.
Connections between our core competencies are strong, with theoretical, experimental and computational work typically pursued in tandem.
A network of collaboration at all levels sustains a research climate that is both vigorous and friendly. Here new ideas develop in conversation, stimulated by the steady activity of our labs and research groups, frequent student meetings with faculty, regular talks by local and invited scholars and collaborations with the broader University of Maryland language science community, the largest and most integrated language science research community in North America.
A number of recent electrophysiological studies of sentence processing have shown that a subclass of syntactic violations elicits very rapid ERP responses, occurring within around 200 ms of the onset of the violation. Such findings raise the question of how it is possible to diagnose violations so quickly. This paper suggests that very rapid diagnosis of errors is possible specifically in situations where the diagnosis problem is tightly constrained by specific expectations generated before the critical word is presented. In an event-related potentials (ERP) study of visual sentence reading participants encountered violations of a word order constraint (...Max’s of...) that has elicited early ERP responses in previous studies. Across conditions the illicit sequence was held constant, while sentence context was used to manipulate the expectation for a noun following the possessor Max’s, by manipulating the possibility of ellipsis of the head noun. Results showed that the anterior negativity elicited by the word category violation was attenuated when the availability of ellipsis reduced the expectation for a noun in the position of the offending preposition of, with divergence between conditions starting around 200 ms after the onset of the violation. This suggests a role for structural expectations in accounting for very fast syntactic diagnosis processes.

In this thesis, I propose a syntactic structure for verbs which directly encodes their event complexities. I present a model that is 'internalist' in the Chomskyan sense: Aktionsart properties of predicates are not a real-world affair, but the interpretation of a mind structure. For this purpose, I base my proposal on the Dimensional Theory of Uriagereka (2005, forthcoming). Syntactic constructs are in this view the results of operations that create increasingly complex objects, based on an algorithm that is homo-morphic with the structure of numerical categories. First, I propose that Aktionsart can be read off from structural complexities of syntactic objects and their associated 'theta-roles'. Specifically, I present the SAAC Hypothesis: Syntactic complexity in a verb is reflected in the number of syntactic arguments it takes. This approach, within the confines of the Dimensional Theory, results in an emergent 'thematic hierarchy': Causer > Agent > Locative > Goal > Theme. I test the accuracy of this hierarchy and concomitant assumptions through paradigms like the control of implicit arguments, selectional properties of verbs, extractions, aspect-sensitive adverbials, etc. Second, I argue that the verbal structure I propose is syntactically and semantically real, by extending the proposal in Lasnik (1999) on VP ellipsis from inflectional to derivational morphology. I discuss two contrasting methods of morphological amalgamation in English and Japanese, executed in Syntax and PF, respectively. This demonstrates a tight network of entailment patterns that holds of verbs, derived crucially from the architecture I argue for. Third, an analogous point is made through the structural positionings of causative and inchoative derivational morphemes in Japanese. There, each order of structural complexity has a profound impact on the class of eventualities a derivational morpheme can describe. 'Dimensional talks' are observed between certain derivational morphemes, which presumably find their roots in operations of the computational system within the Dimensional Theory. I show that the verbal structure in Japanese reflects directly an underlying bi-clausality that I argue for, in terms of derivational morphemes, further supporting a natural mapping between syntax and semantics. This is, in the end, an attempt for a 'Minimalist' theory of Aktionsart.
In this thesis, I present evidence that structural Case in Korean is not absolutely semantically inert. It can have a focus flavor in some contexts, for example, stacked Case and Case attached to an adverb/adverbial and a verb. This sort of Case feature may not be an embarrassment for the good design of language. I discuss the Resultative Construction in a derivational approach. We compare the Resultative Construction between English and Korean in pursuit of finding out the underlying cause for differences between the two languages.
The aim of the present study is to revisit the old debate between rationalists and empiricists in relation to language development with new longitudinal data in hand. I show that when it comes to the development of a specific piece of linguistic knowledge, namely the distribution of the third person singular morpheme -s in child English, the generativist approach can satisfactorily account for the quirks observed in the longitudinal data presented herein. First, I argue that children are not conservative learners in the sense of Tomasello (2003), but they set parameters in the sense of Crain (1991). That is to say, child grammars may vary from the adult -significantly-, but the variation is conservatively limited by the hard-wired principles and parameters of Universal Grammar. I conclude that a parameter setting account of the development of functional categories is preferred as it attains explanatory adequacy with a minimal set of assumptions. I then adopt Lasnik's (1995a) parametric account of verbal morphology, which distinguishes two types of Infl(ectional) items: affixal Infl and featural Infl. Furthermore, I use the same distinction to account for the development of sentential Neg(ation), as well, arguing that there are two parametric values associated with the Neg(ation) category: affixal Neg and featural Neg. In natural languages, the intersection of these values defines different grammars (e.g. Swedish vs. English, Middle English vs. Modern English). Based on the Principles and Parameter theory, I show that at any given point in development, innately hard-wired UG principles and parameters can accurately define child grammars the same way they define any natural language. I argue that longitudinal evidence suggests that these parametric values are hard wired as those options are explored by four different English-speaking 2-year-old children. Thus, I conclude that language development is better understood as language change driven by parameter setting and re-setting.
