Understanding how a child's language system develops into an adult-like system is a central question in language development research. An increasingly influential account proposes that the brain constantly generates top-down predictions and matches them against incoming input, with higher-level cognitive models serving to minimize prediction…

Reading is an essential skill for daily life and academic success. According to the connectionist model of reading, word recognition involves orthographic, phonological, and semantic processing, as well as the interactions among them. Language skill such as phonological processing, develops earlier than reading acquisition, and thus likely serves…

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…

Native-English speaking adults use morphological decomposition to understand complex words (e.g. "farmer" becomes "farm-er"). Whether decomposition is driven by semantic organization is still unclear. It is also unclear whether ESL adults and elementary age children use the same word processing strategies as native speaking…

Research on morphological awareness has shown that it contributes to literacy outcomes. However, because of the way morphological awareness is traditionally measured, there is speculation that tasks may reflect cognitive flexibility, working memory, or some other type of executive processing, versus awareness of morphology. Further complicating…

When considering the most discernible indicator of dyslexia, most researchers have agreed that phonological awareness is perhaps the most pertinent sign (Gillon, 2004; Hallahan & Kauffman, 2006; Lyon, Shaywitz, & Shaywitz, 2003). However, is this true in languages other than English? How does orthography affect phonological…

The research in this dissertation describes a Grounded Theory approach to identifying critical knowledge components of Teacher Content Knowledge (TCK) and Teacher Pedagogical Knowledge (TPK) for ESL teachers who must teach reading to young English language learners, often with little literacy training The research explored how professional…

Empirical evidence suggests oral language proficiency is correlated with literacy outcomes; however, the relationship between oral language proficiency and literacy outcomes for English Language Learners is highly variable. As a result, the field lacks critical direction to identify children who are English Language Learners experiencing general…

As a group, children with hearing loss demonstrate delays in language development relative to their peers with normal hearing. Early intervention has a profound impact on language outcomes in children with hearing loss. Data examining the relationship between degree of hearing loss and language outcomes are variable. Two approaches are used in the…

Six experiments explored how native and non-native Spanish speakers process article-noun sequences in real time, using eye movements as a response measure. Can listeners use gender-marked articles ("la" and "el", the feminine and masculine forms of "the") to rapidly identify familiar and novel nouns? In Experiment 1, adults who learned Spanish as…
