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…

Scalar inference, the process by which we infer meanings stronger than what was explicitly said, has long been a central topic of investigation in theoretical semantics-pragmatics, as well as in psycholinguistics. Upon encountering the sentence "Mary ate some of the deep dish", for instance, hearers regularly compute the pragmatic…

Conceptual representations can be altered to align with the current context given learning and task goals. One cognitive process, known as conceptual combination, allows for a unique perspective for exploring how complex conceptual processing occurs and how this processing influences the underlying representations of concepts. During novel nominal…

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…

The process of spoken word recognition is influenced by both bottom-up sensory information and top-down cognitive information. These cues are used to process the phonological and semantic representations of speech. Several studies have used EEG/ERPs to study the neural mechanisms of children's spoken word recognition, but less is known about the…

One of the fundamental questions in the field of language acquisition is a learnability problem, which considers how learners acquire certain aspects of language which are not directly provided in the input or whose referents are not readily observable. This dissertation investigates Japanese children's acquisition of various linguistic phenomena,…

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…

Some links between linguistic meanings and markers change systematically and cyclically in what are known as "grammaticalization paths." Although the empirical observations that give rise to these characterizations are cross-linguistically robust, the representations and cognitive processes that support these shifts are still not well…

Traumatic brain injuries (TBIs) are heterogeneous in nature and commonly result in deficits to multiple areas of cognition including memory, linguistic processing, and executive functioning. For individuals with TBI, returning to everyday activities can be a challenge with their quality of life reduced by a variety of impairments including…

High level reading comprehension is a process that results in a reader's semantic interpretation of a text, or mental model of that text, referred to as the "reader's situation model." Individual differences in readers' verbal working memory resources, as measured by reading span tasks (RST), and operation span tasks (OST), have shown to…

This research improves the precision of information extraction from free-form text via the use of cognitive-based approaches to natural language processing (NLP). Cognitive-based approaches are an important, and relatively new, area of research in NLP and search, as well as linguistics. Cognitive approaches enable significant improvements in both…

Prospective memory (PM) refers to memory for future intentions (e.g. remembering to press a button when you see an animal word). Researchers classify PM intentions in the laboratory as focal or nonfocal primarily in two ways. One way, task-appropriateness, refers to how the processing for the intention relates to the processing required for an…

An over-arching goal in neurolinguistic research is to characterize the neural bases of semantic representation. A particularly relevant goal concerns whether we represent features and events (a) together in a generalized semantic hub or (b) separately in distinct but complementary systems. While the left anterior temporal lobe (ATL) is strongly…

Definite descriptions have a number of different readings, the most prominent being the referential and attributive readings. On the referential reading, the description "The current President of the USA" is interpreted as "Barack Obama"; read attributively, it is interpreted as "the current President of the USA, whoever…

This study investigates the relationship between three linguistic functions: thetics, miratives and exclamatives. Thetics are an information structure configuration that conveys that the information is new to the addressee. The thetic subtypes selected for this study are the following: existentials (e.g. "There are apples in the…
