Ambiguity is a natural part of language and in studying the comprehension and resolution of ambiguity in a second language (L2), we must consider the influence of the native language. This dissertation examines L2 processing of the lexical semantic ambiguities, homonyms and polysemes. These are words that share the same form but have different…

When individuals read a narrative text, they construct a mental representation known as a situational model to comprehend the unfolding story. These models require updates at meaningful changes in the story to reflect current information accurately. Existing research highlights the attentional and working memory demands of these updating…

Embodied models of language comprehension assume that words become associated with sensorimotor experiences during word learning. Novel word learning paradigms may provide insight into embodied effects, but studies in this domain have yet to account for how concepts and information known in first language (L1) might influence the sensorimotor…

Collocations are words that have a tendency to co-occur within a few words' spans, e.g., "drink coffee" and "dark chocolate" in English. Growing empirical evidence suggests that both native (L1) speakers and advanced second language (L2) learners process two-word collocations faster than unconnected word pairs, and that…

Scope ambiguity arises when a sentence contains scope-bearing logical operators like quantifiers and negation (Fox, 2003). For instance, in English, the sentence 'Every horse didn't jump over the fence' can be interpreted as either 'None of the horses jumped over the fence' (surface scope) or 'Not all of the horses jumped over the fence' (inverse…

Second language acquisition has been observed to be variable in its outcome such that, unlike native speakers, all second language learners do not achieve total success. Second language acquisition is made of macro and micro processes. External and internal (e.g., age, individual differences) factors are assumed to affect language processing in…

Individuals with lower proficiency in a second language tend to produce more disfluent speech patterns in the second language. Speech disfluencies refer to interruptions in the forward flow of speech and are distinct from the colloquial use of "fluency," to characterize knowledge of a language. Prior research indicates that some speech…

Over the last two decades, there has been an increasing interest in third language (L3) phonology (Cabrelli Amaro, 2012; Cabrelli Amaro & Wrembel, 2016). However, research so far has been primarily directed at specific stages of learning and has independently explored either production (e.g., Llama, Cardoso, & Collins, 2010; Llama &…

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…

Analysis of second language (L2) learners' language development can allow valid and reliable assessment of the learners' L2 linguistic knowledge, which can enable the teachers and researchers to choose appropriate teaching or experimental materials (Bardovi-Harlig & Bofman, 1989; Wolfe-Quintero et al., 1997). However, most language development…

Studies assessing the grammatical knowledge of speakers of Spanish as a heritage language have largely focused on the Spanish subjunctive mood and have concluded, almost unanimously, that heritage speakers' knowledge of the Spanish subjunctive is non-native-like and subject to incomplete acquisition. However, there is also evidence that while…

This dissertation study explored the feasibility of using authenticated spoken texts to test L2 Chinese listening comprehension. The spoken texts used in the study were created using an "authenticating" technique, in which scripted spoken Chinese texts were infused with characteristics of real-world, unscripted spoken Chinese. In the…

Language exposure plays a large role in language acquisition, and bilingual children must acquire both of their languages in environments that typically include abundant speech variability. The specific goals of this dissertation were to examine how speech exposure affected phonological retuning and lexical access in bilingual children's second…

This study aimed to investigate the effect of written cues on the second- language (L2) language perception, processing, and word learning, especially when the person's first language (L1) belongs to a different rhythmic type of language than L2. The first objective was to examine whether late bilinguals as L2 learners can benefit more from…

Languages generally use musical pitch variation of the voice as part of their sound systems (Maddieson, 2011)--pitch variations that can be somewhat reminiscent of music. Music ability and/or training may influence language processing (e.g., Bidelman et al., 2011; Delogue et al., 2010). In particular, studies have concluded that there may be a…
