For more than a decade, research on heritage speakers' (HSs') mood selection has documented a high degree of variability in their interpretation and use of mood morphology in variable contexts. Most of the previous literature, however, has focused on late-acquired alternations, and often limited analyses to one form (i.e., subjunctive), making it…

This dissertation studies the acquisition of Mandarin relative clauses (RCs), including the distributional pattern of different RC types in adult child-directed speech (study 1) and four-year-old Mandarin-speaking children's comprehension of different RC types (study 2). An RC is a subordinate clause that modifies a noun and is embedded within a…

Age of acquisition (AoA) refers to the age at which people learn a particular item and the AoA effect refers to the phenomenon that early-acquired items are processed more quickly and accurately than those acquired later. Over several decades, the AoA effect has been investigated using neuroscientific, behavioral, corpus and computational…

In phonetics research, language alternation--including code switching (speaker-initiated) and cued switching (researcher-prompted)--can be used as a tool to investigate various aspects of speech production and perception in bilingual or multilingual speakers (Bullock & Toribio, 2009a). Studies on the production of voice onset time (VOT) during…

Four picture-description experiments investigated if syntactic formulation in language production can proceed with only minimal working memory involvement. Experiments 1-3 compared the initiation latencies, utterance durations, and errors for syntactically simpler picture descriptions (adjective-noun phrases, e.g., "the red book") to…

A great deal of the research on cross-linguistic phonetic influence demonstrates that a speaker's knowledge of their first language (L1) significantly affects their ability to perceive and produce sounds in any other language. While current studies show that cross-linguistic transfer occurs at the L3 level, some research suggests that properties…

In 2005, Klaus P. Schneider published a fascinating article with the title "'No problem, you're welcome, anytime': Responding to thanks in Ireland, England, and the U.S.A." Adopting the then emerging and now established framework of variational pragmatics, Schneider's pioneering paper presents the results of a study on differences…

This dissertation investigated the speech productions of the implosive -r consonant by U.S.-born Puerto Rican and Dominican Heritage Language Spanish speakers in New York. The following main research questions were addressed: 1) Do heritage language Caribbean Spanish speakers evidence the same variation with the /?/ consonant in the implosive…

While considerable dialectal variation exists, almost all varieties of Spanish exhibit some sort of alternation in terms of the palatal obstruent segments. Typically, the palatal affricate [??] tends to occur in word onset following a pause and in specific linear phonotactic environments. The palatal fricative [?] tends to occur in syllable onset…

This book focuses on theory, research, and practice related to "lexical input processing" (lex-IP), an exciting field exploring how learners allocate their limited processing resources when exposed to words and lexical phrases in the input. Unit 1 specifies parameters of lex-IP research among other levels of input processing as well as…

English-speaking children understand and produce generic expressions in the preschool years, but there are cross-linguistic differences in how generics are expressed. Three studies examined interpretation of generic noun phrases in three- to seven-year-old child (N=192) and adult speakers (N=163) of Mandarin Chinese. Contrary to suggestions by…

Speakers of gender-agreement languages use gender-marked elements of the noun phrase in spoken-word recognition: A congruent marking on a determiner or adjective facilitates the recognition of a subsequent noun, while an incongruent marking inhibits its recognition. However, while monolinguals and early language learners evidence this…

The present investigation examines English speakers' ability to identify and discriminate non-native consonant length contrast. Three groups (L1 English No-Instruction, L1 English Instruction, and L1 Finnish control) performed a speeded forced-choice identification task and a speeded AX discrimination task on Finnish non-words (e.g.…

The quantifier "dou" (roughly corresponding to English "all") in Mandarin Chinese has been the topic of much discussion in the theoretical literature. This study investigated children's knowledge of this quantifier using a new methodological technique, which we dubbed the Question-Statement Task. Three questions were addressed: (i) whether young…

This experiment measured teachers' attitudes towards African American English and Academic English. Participants were graduate students of Education at a college in New York City. They completed a paper-and-pencil questionnaire that assessed their explicit attitudes towards the two varieties, as well as a Psycholinguistic Experiment that was…
