Previous studies have used semantic verb categories to compare how speakers with and without aphasia use verb types during narrative monologue discourse tasks. In this study, we explore the types of verbs used by speakers with and without aphasia during conversation. Using previously collected conversational discourse samples produced by 23 adults…

How can syntactic and learnability analyses inform each other, and thus deepen our understanding of syntax and its acquisition? This dissertation illuminates this question through three case studies in Korean syntax. I examine cases in which two structures that display distinct syntactic properties share extremely similar surface forms, thus…

Knowledge of collocations facilitates second language (L2) learning by enhancing accuracy and fluency. However, acquiring L2 collocations is often challenging for learners. One factor contributing to this difficulty is incongruency between first and second languages (e.g., "draw distinctions" in English corresponds to do…

To learn the meaning of a new word, or to recognize the meaning of a known one, both children and adults benefit from surrounding words, or the sentential context. Most of the evidence from children is based on their accuracy and efficiency when listening to speech in their familiar native accent: they successfully use the words they know to…

Purpose: Following the Rehabilitation Treatment Specification System (RTSS) framework, the current study investigated the active ingredients in the modified semantic feature analysis (mSFA) targeting either noun or verb retrieval in Mandarin-English bilingual adults with aphasia (BWA). Method: Twelve Mandarin-English BWA completed mSFA treatment…

Purpose: Production of complex syntax is a hallmark of later language development; however, most of the research examining age-related changes has focused on adolescents or analyzed narrative language samples. Research documenting age-related changes in the production of complex syntax in elementary school-aged children in conversational language…

When infants hear sentences containing unfamiliar words, are some language-world links (such as noun-object) more readily formed than others (verb-predicate)? We examined English learning 14-15-month-olds' capacity for linking referents in scenes with bisyllabic nonce utterances. Each of the two syllables referred either to the object's identity,…

Verb morphology difficulties have been widely attested in children with developmental language disorder (DLD) who speak English and other languages. This research contributes data on a variety of Arabic, a richly inflected Semitic language. The current study examined the production of subject-verb agreement morphology in three groups of 30…

Purpose: The purpose of this study is to determine if 2.5-year-olds with language delay would learn verbs ("spill") when presented with varying syntactic structure ("The woman is spilling the milk"/"The milk is spilling"; "milk" = patient or theme) in a therapeutic context. Children with language delay have…

A B S T R A CT Purpose: Retrieval practice has been shown to assist the word learning of children with developmental language disorder (DLD). Although this has been true for learning new verbs as well as new nouns and adjectives, these children's overall verb learning has remained quite low. In this preregistered study, we presented novel verbs in…

Conventional metaphors are a fundamental component of everyday communication, yet they are often overlooked in post-secondary German-language programs. This study examines the extent to which vocabulary breadth influences 19 L2 German learners' comprehension of conventional German metaphors, particularly those that exhibit cross-linguistic…

Recent investigations on how people derive meaning from language have focused on task-dependent shifts between two cognitive systems. The symbolic (amodal) system represents meaning as the statistical relationships between words. The embodied (modal) system represents meaning through neurocognitive simulation of perceptual or sensorimotor systems…

Verb-marking errors such as "she play football" and "daddy singing" are a hallmark feature of English-speaking children's speech. We investigated the proposal that these errors are input-driven errors of commission arising from the high relative frequency of subject + unmarked verb sequences in well-formed child-directed…

Causation is a core feature of human cognition and language. How children learn about intricate causal meanings is yet unresolved. Here, we focus on how children learn verbs that express causation. Such verbs, known as lexical causatives (e.g., break and raise), lack explicit morphosyntactic markers indicating causation, thus requiring that the…

Greek and Spanish are two languages that display a similar subject distribution with unergative/unaccusative verbs, but different word orders with focused subjects (SV in Greek and VS in Spanish). Here we consider subject-verb word order in second language (L2) Greek and L2 Spanish in order to test the Interface Hypothesis (IH). To this end, we…
