In two visual world eye-tracking experiments, this dissertation examines the role of literacy on predictive processing during spoken language comprehension. Previous studies have shown that comprehenders can use morphosyntactic cues available in the input to generate predictions about upcoming information. Recent key findings also suggest that…

Given that both spoken and written language are subject to corruption from speech errors, disfluencies, and environmental noise, successful language comprehension sometimes requires deriving a non-veridical understanding of the linguistic input. Recent work has demonstrated that these non-veridical understandings are not merely semantic, but that,…

How do infants learn about the formal properties of language using only cues they can access in speech? And what intuitions do they bring to the learning problem? Chapter 2: To explore whether current notions of statistically-based language learning could successfully scale to infants' linguistic experiences "in the wild", we implemented…

This dissertation focuses on strategies and techniques to enhance code comprehension skills among students enrolled in introductory computer science courses (CS1 and CS2). We propose a novel tutoring system, "DeepCodeTutor," designed to improve the code comprehension abilities of novices. DeepCodeTutor employs scaffolded self-explanation…

This study aimed to investigate the following questions: Does the use of thinking maps and semantic mapping during explicit vocabulary instruction affect content specific science vocabulary knowledge and comprehension in fourth grade students? and What are student perceptions of using thinking maps and semantic maps to learn new vocabulary? To…

Meaning construction is a complex concept that encapsulates language and thought as a whole system in which sense and meaning have a unique relationship highly marked by the social and cultural environment of the reader. Hence, Kichwa-Spanish bilinguals' reading practices in the Southern Andes of Ecuador cannot be discussed as two separate…

Emojis are nonverbal elements used in text-based communication that may function like gestures in spoken communication (Feldman et al., 2017; McCulloch & Gawne, 2018). Like words, emojis can convey semantic information and support message comprehension (Lo, 2008; Riordan, 2017b). Nevertheless, the cognitive and perceptual processes involved in…

Psycholinguistic research aims to understand how people make sense of language in their everyday lives. However, most of this research studies language under experimental conditions in which people are instructed to specifically monitor (and indicate) when there is a breakdown in their understanding. Moreover, there is an assumption that people…

This dissertation investigates the ways that natural languages evolve and what it means in the overall cultural evolution of society. Computational and modeling advances have made possible to explore large-scale text data and test hypothesis of language evolution. Similar to biological systems, natural languages are evolving systems with words as…

The present dissertation intends to investigate the syntactic nature and L2-acquisition of passive sentence structure in two Romance varieties, Italian and Spanish. First, I will present an analytic proposal couched within the Generative Approach (Chomsky, 1957, and subsequent work); from there, and following Perlmutter and Postal's (1977)…

Reading comprehension can be analyzed from three points of view: Semantics, Assessment, and Cognition. Here, Semantics refers to the task of identifying discourse relations in text. Assessment involves utilizing these relations to obtain meaningful question-answer pairs. Cognition means categorizing questions according to their difficulty or…

The vocabulary deficit shown by English Learners (ELs) has become evident among many educators over decades of research (Becker, 1977; Biemiller, 2001; Chall, Jacobs, & Baldwin, 1990; Hart & Riseley, 2003), and has shown that a student's limited vocabulary becomes a "major barrier to school success" (Graves, 2005, p. 18).…

Items in the mental lexicon have three storage and processing strata, the concept, lemma, and lexeme, which equate to semantic, syntactic and phonological information. Lexical items relate to each other at each stratum. Bilingual lexicons, which contain items from all languages, may contain cognates, items sharing concepts and with overlapping…

Semantic illusions are recognition errors that occur when an individual fails to notice that information contradicts their prior knowledge (Barton & Sanford, 1993; Erickson & Mattson, 1981). For example, after hearing the question, "If a plane crashes while flying over state lines, where should the survivors be buried?" many…

Language comprehension is remarkable in that we adapt easily to different forms of language use, from adapting to speakers' dialects, meanings of new slang words, and fictional worlds described in novels. While there is growing evidence comprehenders adapt their expectations for text during reading, the nature of these adaptation mechanisms…
