This study investigates the perception and production of a specific type of metaphoric gesture that mimics melody in speech, also called "pitch gesture," in the learning of L2 suprasegmental features. In a between-subjects design, a total of 106 participants with no previous knowledge of Chinese were asked to observe (Experiment 1) and…

In this dissertation, I investigated how cognitive resources as well as formal, and informal language experience impact language learning in two studies. In the first study (Chapter 2), I examined the learning of Spanish grammatical gender by Chinese international students who were studying abroad in the US. The goal of that study was to uncover…

Using a novel emotional perspective-taking task, this study investigated 4-year-olds' (n = 97) use of a speaker's emotional prosody to make inferences about the speaker's emotional state and, correspondingly, their communicative intent. Eye gaze measures indicated preschoolers used emotional perspective inferences to guide their real-time…

This study examined Spanish-Welsh (in Patagonia) and Welsh-English (in North Wales) bilingual children's and adults' processing of sentences in which two noun phrases acted as arguments of a verb. The goal was to determine the relative importance of distinct cues to the identification of the subject in the bilinguals' processing of their two…

One strategy that children might use to sort words into grammatical categories such as noun and verb is distributional bootstrapping, in which local co-occurrence information is used to distinguish between categories. Words that can be used in more than one grammatical category could be problematic for this approach. Using naturalistic corpus…

Terminal changes in fundamental frequency provide the most salient acoustic cues to declarative questions, but adults sometimes identify such questions from pre-terminal cues. In the present study, adults and 7- to 10-year-old children judged a single speaker's adult- and child-directed utterances as questions or statements in a gating task with…

This study investigates 3- to 5-year-old children's sensitivity to lexical, intonational and gestural information in the comprehension of speaker uncertainty. Most previous studies on children's understanding of speaker certainty and uncertainty across languages have focused on the comprehension of lexical markers, and little is known about the…

This dissertation investigates the occurrence of an intermediate stage, termed a covert contrast, in the acquisition of Mandarin Tone 2 (T2) and Tone 3 (T3) by adult speakers of American English. A covert contrast is a statistically reliable distinction produced by language learners that is not perceived by native speakers of the target language…

Purpose: The objective was to investigate acoustic cue processing in lexical-tone recognition by pediatric cochlear-implant (CI) recipients who are native Mandarin speakers. Method: Lexical-tone recognition was assessed in pediatric CI recipients and listeners with normal hearing (NH) in 2 tasks. In Task 1, participants identified naturally…

Word order is a core mechanism for conveying syntactic structure, yet interrogatives usually disrupt canonical word orders. For example, in English, polar interrogatives typically invert the subject and auxiliary verb and insert an utterance-initial "do" if no auxiliary is present. These word order patterns result from differences in the…

Tonal languages differ in how they use phonetic correlates, e.g. average pitch height and pitch direction, for tonal contrasts. Thus, native speakers of a tonal language may need to adjust their attention to familiar or unfamiliar phonetic cues when perceiving non-native tones. On the other hand, speakers of a non-tonal language may need to…

Purpose: To investigate sensitivity to prosodic and semantic cues to emotion in individuals with high-functioning autism (HFA). Method: Emotional prosody and semantics were independently manipulated to assess the relative influence of prosody versus semantics on speech processing. A sample of 10-year-old typically developing children (n = 10) and…

This paper focuses on the particular kinds of difficulties which arise in the study of an emergent tone-system, exemplified by Tamang in Nepal, where pitch, phonation and other laryngeal features combine in the definition of a tone. As a consequence, conducting a well-ordered analysis in stages first of phonetic transcription, then variation in…

This study explored the feasibility of training school teaching assistants to provide the treatment, Dynamic Temporal and Tactile Cueing to treat childhood apraxia of speech (CAS, also known as developmental verbal dyspraxia). The study used a single case experimental design across behaviours and a qualitative evaluation of teaching assistant…

The role of prosodic information in sentence processing is not usually addressed in second language (L2) instruction, and neurocognitive studies on prosody-syntax interactions are rare. Here we compare event-related potentials (ERP) of Chinese and German learners of English L2 to those of native English speakers and show how first language (L1)…
