Eventualities have been recognized as psychologically and linguistically relevant for more than 50 years. Psychologically, eventualities are complex bundles of information derived from our perceptions of the world. The question for linguists is how much of this complexity is reflected in our eventuality-denoting lexical entries and the…

The present study aims at providing a descriptive account of the unaccusative verbs in Jordanian Arabic dialect (henceforth, JA) in terms of Transitivity. It also aims at presenting empirical evidence to prove that a split projection analysis is appropriate for unaccusative predicates in JA in light of the Minimalist Approach (Chomsky, 1995,…

We investigate concrete acquisition theories for a derived approach to linking theory development and explore to what extent two prominent linking theories in the syntactic literature--UTAH and rUTAH--can be derived from the data that English-learning children encounter. We leverage a conceptual acquisition framework that specifies key aspects of…

Using computational simulations, this work demonstrates that it is possible to learn a systematic relation between words' sound and their meanings. The sound-meaning relation was learned from a corpus of phonologically transcribed child-directed speech by using the linear discriminative learning (LDL) framework (Baayen, Chuang, Shafaei-Bajestan,…

The Mayan language Mam uses complex predicates to express events. Complex predicates map multiple semantic elements onto a single word, and consequently have a blend of lexical and phrasal features. The chameleon-like nature of complex predicates provides a window on children's ability to express phrasal combinations at the one-word stage of…

One of the fundamental questions in the field of language acquisition is a learnability problem, which considers how learners acquire certain aspects of language which are not directly provided in the input or whose referents are not readily observable. This dissertation investigates Japanese children's acquisition of various linguistic phenomena,…

This article focuses on the role of crosslinguistic patterns with verbs in the mapping of noun phrases/semantic roles to positions in morphosyntax, with a particular focus on second language (L2) development of Spanish "se." The data set derives from high school learners of Spanish in the United States under broadly deductive and…

This research addresses implicit learning of temporal meanings in English by adult non-native readers of German, a language without morphosyntactic imperfective aspect. Twenty-four learners from mixed first languages participated in a norming study assessing unenhanced aspect awareness. Then, in a second experiment, 91 native-German learners…

The present study examines the production and intuition of Spanish clitics in clitic left dislocation (CLLD) structures among 26 Spanish heritage speakers (HSs) born and raised in Brazil. We tested clitic production and intuition in contexts in which Spanish clitics vary as a function of the semantic features of the object that they refer to.…

Effects of concreteness and grammatical class on lexical-semantic processing are well-documented, but the role of sensory-perceptual and sensory-motor features of concepts in underlying mechanisms producing these effects is relatively unknown. We hypothesized that processing dissimilarities in accuracy and response time performance in nouns versus…

The Interface Hypothesis proposes that second language (L2) learners, even at highly proficient levels, often fail to integrate information at the external interfaces where grammar interacts with other cognitive systems. While much early L2 work has focused on the syntax-discourse interface or scalar implicatures at the semantics-pragmatics…

This study tests the Competing Systems Hypothesis (CSH) as applied to adult second language acquisition of aspect in Spanish. The CSH purports that differences among tutored and untutored learners result from competition between one system of underlying grammatical knowledge and another of learned metalinguistic knowledge in tutored learners…

This paper revisits the longstanding observation that children produce modal verbs (e.g., must, could) with their root meanings (e.g., abilities, obligations) by age 2, typically a year or more earlier than with their epistemic meanings (e.g., inferences). Established explanations for this "Epistemic Gap" argue that epistemic language…

The second language (L2) acquisition of tense, aspect, and mood/modality (TAM) has been widely explored as it holds the promise of a better understanding of the L2 learners' linguistic competences, particularly semantically and morpho-syntactically. This study focuses on the acquisition of the subjunctive mood by L1 English learners of L2 French…

Understanding language requires the ability to compose the meanings of words into phrase and sentence meanings. Formal theories in semantics have framed the hypothesis that all instances of meaning composition, irrespective of the syntactic and semantic properties of the expressions involved, boil down to a unique formal operation, that is, the…
