Language comprehension requires a complex series of decisions under uncertainty. This is especially obvious when one string may have multiple different interpretations, whether due to lexical ambiguity, or the potential for an inference beyond literal content. This dissertation profiles how the human system for language comprehension times those…

Evidence from neuropsychological studies of individuals with brain damage post-stroke has supported the separation of working memory (WM) capacities for semantic (word meaning) and phonological (speech sound) information. These separate capacities have been shown to play different roles in supporting multiword language production, with semantic WM…

Since corpus linguistics gained popularity as a methodology in the latter half of the 20th century, second language acquisition research has seen the emergence of work investigating formulaic language, such as idioms, lexical bundles, and collocations. A collocation is a string of words that co-occur more routinely than probability would predict,…

Interaction has received attention in different fields of applied linguistics. In the field of Second Language Acquisition (SLA), scholars have perceived interaction as a platform where L2 learners can engage in language experimentation. It has been considered in light of Long's (1981) Interaction Hypothesis, which posits that negotiation of…

This dissertation investigates how bilinguals use their two grammars to comprehend written intra-sentential codeswitches. I focus on adjective/noun constructions in Spanish and English where I manipulate the congruence of grammatical word order in the two languages across the codeswitch boundary. This allows me to test three codeswitching…

Typically developing (TD) children, as young as four years of age, have demonstrated enhanced noun learning when orthographic representations are presented during learning tasks. This dissertation investigated the impact of orthographic support on word learning in diverse populations, focusing on children from a variety of clinical categories…

This dissertation explores Spanish nominal plural formation from a morphophonological perspective. The primary objective is to better understand heritage bilinguals' (HBs') phonological categorization of the morphological element of number in their heritage language. This is done by way of picture-naming elicitation tasks of consonant-final nouns…

A growing number of studies has shown that collaborative writing tasks facilitate second language (L2) development by providing learners with opportunities to focus their attention on language and to collaborate in the solution of their language-related problems (e.g., Choi & Iwashita, 2016; Storch, 2013; Swain & Lapkin, 1998; Williams,…

Researchers in the field of second language acquisition continue to establish links between cognition and emotion (Dewaele, 2013; MacIntyre, 2002; MacIntyre & Gardner, 1989, 1991b, 1994; Segalowitz & Trofimovich, 2011). The purpose of the present study is to investigate to what extent physiological and self-report measures predict…

This dissertation introduces and evaluates a new methodology for studying aspects of human language processing and the factors to which it is sensitive. It makes use of the phoneme restoration illusion (Warren, 1970). A small portion of a spoken sentence is replaced by a burst of noise. Listeners typically mentally restore the missing phoneme(s),…

Despite considerable evidence suggesting that second language (L2) learners experience difficulties when processing morphosyntactic aspects of L2 in online tasks, the mechanisms underlying these difficulties remain unknown. The aim of this dissertation is to explore possible causes for the difficulties by comparing attentional mechanisms engaged…

Researchers have recently described a new processing task in which rating words on the basis of their survival or fitness relevance leads to better recall and recognition performance than several other well known deep processing tasks. The present study was designed to determine whether this survival processing advantage could be observed when…

There is much evidence demonstrating that bilinguals activate lexical representations from both of their languages in a non-selective manner even in sentence context. Comparatively less research has examined the extent to which bilingual lexical representations interacts with syntactic processing in sentence context. The purpose of this study is…

Previous literature shows that language input is related to the language that children produce. Less is known about how the input provided to children relates to the way that they process language. In this study, this question was explored by looking at the relationships between children's word learning ability and the kinds of names provided by…

This dissertation investigates the role of grammatical gender facilitation and inhibition in second language (L2) learners' spoken word recognition. Native speakers of languages that have grammatical gender are sensitive to gender marking when hearing and recognizing a word. Gender facilitation refers to when a given noun that is preceded by an…
