This dissertation is about the learnability of different generative, Separationist approaches to nominal morphosyntax. The core of my investigation is number, gender, and declension class, as manifested across nouns, adnominals (adjectives, numerals, demonstratives, and quantifiers), and articles. An extreme position would require that all of…

Evidence of sensitivity to graphotactic and morphological patterns in English spelling has been extensively examined in monolinguals. Comparatively few studies have examined bilinguals' sensitivity to spelling regularities. The present study compared late Chinese-English bilinguals and English monolinguals on their sensitivity to systematic…

Previous studies show that infants store functional morphemes for inferring syntactic categories of adjacent words, and they generally perform better with nouns than with verbs. In this study, we tested whether toddlers can exploit phrasal groupings for syntactic categorization in the face of noisy co-occurrence patterns. Using a visual fixation…

This paper explores the hypothesis that children pay more attention to phonological cues than semantic cues when acquiring grammatical patterns. In a series of artificial allomorphy learning experiments with adults and children we find support for this hypothesis but only for those learners who do not show clear signs of explicit learning. In…

We examine the syntactic structures exhibited by persons with dementia in conversation. Traditionally, research on the linguistic abilities of persons with dementia is either observational (reports kept by caregivers) or experimental (e.g. based on comprehension tasks), and the focus is not on the syntactic competence of the speaker. We combine…

Corpora are well-known for the affordance to make linguistic regularities salient. Since the coinage of the term 'data-driven learning' (DDL) in the 1990s, much has been done to investigate the effects of DDL on learning vocabulary, most notably lexico-grammatical patterns. However, less researched is how learners construct vocabulary knowledge…

Based on writing produced by second language learners at different proficiency levels (CEFR A1 to C1), we adopted a usage-based approach (Ellis, Römer, & O'Donnell, 2016; Tyler & Ortega, 2018) to investigate how German and Spanish learner knowledge of 19 English verb-argument constructions (VACs; e.g., "V with n," illustrated by…

While previous sociolinguistic research has demonstrated that children faithfully acquire probabilistic input constrained by sociolinguistic and linguistic factors (e.g., gender and socioeconomic status), research suggests children regularize inconsistent input-probabilistic input that is not sociolinguistically constrained (e.g., Hudson Kam &…

Research on linguistic variation suggests that usage patterns are deeply embedded in native and non-native speakers' knowledge of grammar. This study explores the transfer of these variable sociolinguistic patterns at the initial stages of third language acquisition. We elicited narratives in Portuguese from two mirror-image groups of sequential…

Adult learners know that language is for communicating and that there are patterns in the language that need to be learned. This affects the way they engage with language input; they search for form-meaning linkages, and this effortful engagement could interfere with their learning, especially for things like grammatical gender that often have at…

Given that grammatical and spelling errors have been found to influence perceived competence and credibility in written communication, this study examined how a student's grammar and spelling errors affect how other students respond to the student's postings in four online debates hosted in asynchronous threaded discussions. Message-response…

Monolingual and parallel concordancers have both been found to benefit second-language (L2) grammatical development. However, the relative benefits of these two concordancer types remains unclear. The present study compares learning outcomes and learners' perceptions of a monolingual English (Corpus of Contemporary American English, COCA) and a…

The present study aimed to profile the developmental patterns of discourse in second language (L2) writings among different first language (L1) groups. Applying the list of metadiscourse markers proposed by Ken Hyland to learner language, this study investigates variation of metadiscourse across proficiency levels, as well as across L1…

The study aims at identifying characteristic phenotypes for children with SLI and children with sensorineural hearing impairment (HI) in language and in domains associated with language. We focus on verbal agreement inflection and phonological short-term memory, phenomena that have been repeatedly found to be impaired in both groups of children. A…

The aim of this article is to describe the grammatical patterns of a set of nouns frequently used in Spanish specialized discourse: the so-called "semiterms". The following nouns were selected for the study: "problema" "problem", "resultado" "result", "motivo" "motive/reason", "razon" "reason", and "consecuencia" "consequence". Apart from…
