This dissertation interrogates the representation of syntactic locality constraints, specifically intervention locality, within child grammar. Our focal point is the Intervention Hypothesis, which suggests that children are governed by a strict version of featural Relativized Minimality, leading to comprehension difficulties when partial featural…

Attitude verbs like "think" and "want" describe mental states (belief and desire) that lack reliable physical correlates that could help children learn their meanings. Nevertheless, children succeed in doing so. For this reason, attitude verbs have been a parade case for syntactic bootstrapping. We assess a recent syntactic…

Learning to mark for tense in a second language is notoriously difficult for speakers of a tenseless language like Chinese. In this study we test two reasons for these difficulties in Chinese-English sequential bilingual children: (1) morphophonological transfer (i.e., avoidance of complex codas), and (2) interpretation of -"ed" as an…

Mandarin Chinese verbs are composed of one to four characters that function together as a conceptual unit. However, in modern spoken Chinese, most of these verbs are two-character compounds. This dissertation is focused on adult second language (L2) learners' acquisition of these two-character verb compounds. Specifically, the acquisition of a…

Mandarin Chinese and Spanish are both considered aspect languages for the simple reason that they both mark grammatical aspect morphologically: the former attaches a particle expressing only aspectual meaning to the root of a verb, while the latter attaches a suffix expressing both aspectual and tense meaning to the root of a verb. Since tense…

Early trilingual development is an excellent testing ground for input reduction effects on acquisition outcomes. This article reports a study investigating input-outcome relations in a child Leo in Hong Kong, who was addressed to in Mandarin, Cantonese and later also in English by caretakers through 'one caretaker-one language' and 'one day-one…

The Mandarin resultative verb compound (RVC; e.g., "tui dao" "push fall" and "pa shang" "climb ascend") encodes complex events composed of an initiating action and resulting activity or state. This study investigated when Mandarin-speaking children acquired this language-specific device. Specifically, we…

The syntactic structure of sentences in which a new word appears may provide listeners with cues to that new word's form class. In English, for example, a noun tends to follow a determiner ("a"/"an"/"the"), while a verb precedes the morphological inflection [ing]. The presence of these markers may assist children in…

Numerous studies have demonstrated that native Mandarin speakers have pervasive difficulties processing L2 English agreement morphology. However, less is known about the lexical and morphological cues that may modulate Mandarin speakers' sensitivity to English number agreement. To investigate this, we examined subject-verb agreement processing in…

Background: The phonological and morphosyntactic structures of English and Mandarin contrast maximally and an increasing number of bilinguals speak these two languages. Speech and language therapists need to understand bilingual development for children speaking these languages in order reliably to assess and provide intervention for this…

This thesis aims to examine the development of morphosyntax with longitudinal English production from Diany, a Mandarin-speaking child, starting from the second week Diany arrived in the U.S.A. (age 4;9). The study is particularly interested in whether Diany's acquisition of verbal morphemes and verb movement supports relevant hypotheses in the…

This dissertation provides a language processing perspective on the study of second language acquisition (SLA) of tense and aspect. Of special interest are the universal vis-a-vis language-specific dimensions of temporal and aspectual semantics involved. According to the Aspect Hypothesis (AH, e.g. Andersen & Shirai, 1994), the initial…

It is proposed that the functions of the Mandarin verbal suffix "-le" are three: (1) for marking non-continual factual actions or events; (2) for indicating the "peak" in an event line; and (3) for explicitly marking anteriority of an action or event. Observations of written language drawn from newspaper articles and…

Pin-yin transcription is used for Mandarin examples. (RS)

The grammaticalization of "liao" as a main verb in tenth-century vernacular texts to "le" as an aspectual particle in modern Chinese is investigated. The change is attributed to the resultative construction coming into existence in the language and to instances where the verb took sentential subjects or occurred in temporal clauses only. (17…
