This dissertation investigates how the abstract representation of vowels affects spoken word recognition in Brazilian Portuguese and American English by examining two issues in theoretical phonology and speech processing: underspecification theory, and underlying representation when there is alternation. Three experiments were conducted in…

In standard models of language production or comprehension, the elements which are retrieved from memory and combined into a syntactic structure are "lemmas" or "lexical items". Such models implicitly take a "lexicalist" approach, which assumes that lexical items store meaning, syntax, and form together, that…

In recent years, converging evidence has suggested that prediction plays a role in language comprehension, as it appears to do in information processing in a range of cognitive domains. Much of the evidence for this comes from the N400, a neural index of the processing of meaningful stimuli which has been argued to index the extent to which a word…

Language is one of the essential tools used to segment the continuous stream of experience into events. In this process, the choice of words and grammar frames events in different ways. Grammatical aspect plays an important role in representing an event as a complete whole (perfective: peeled) or as a dynamic process (imperfective: was peeling).…

Language learning is a complex issue of interest to linguists, computer scientists, and psychologists alike. While the different fields approach these questions at different levels of granularity, findings in one field profoundly affect how the others proceed. My dissertation examines the perceptual and linguistic generalizations regarding the…

During language comprehension, the brain typically converts a stream of sensory input into meaningful mental representations. But not all of the information the brain needs or uses is physically available in the language signal it encounters: the brain often anticipates and processes some information before it becomes available, and it often also…

Audiovisual (AV) integration, identified as a pivotal factor in comprehending speech in noisy environments, is a complex phenomenon. Understanding speech perception, even within a single modality, presents various nuances due to language specificity. When consolidating information from multiple modalities, it is imperative to understand how the…

This dissertation is a quantitative and qualitative exploration of how one linguistically communicates emotions through an autobiographical narrative. Psycholinguistic research has affirmed that linguistic features of a narrative, including semantic and acoustic features, indicate a narrator's emotions and physiological. This study investigated…

This dissertation explores the relationship between language production processes and recorded typing behaviors among native speakers of English writing in their native language. Typing is quite prevalent in modern societies, as its use is becoming increasingly required in professional and personal settings but it remains largely understudied in…

Previous research has found mixed results for a link between executive function and perspective-taking. One proposed reason for this is that perspective-taking during comprehension tasks may not be internally reliable. This dissertation presents two large individual differences experiments with multiple perspective-taking during comprehension and…

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…

Sociolinguistic variation (SLV) entails that language is affected by social context (i.e. register, pragmatics). Interest in the acquisition of sociolinguistic variation in a second language (L2-SLV), as a key component of communicative competence, has grown exponentially over the past thirty years (Geeslin & Long, 2014). Researchers have…

In this thesis, I use a combination of simulations and empirical data to demonstrate that a small set of structural and functional principles - the basic tenets of predictive coding theory - succinctly accounts for a very wide range of properties in the language processing system. Predictive coding approximates hierarchical Bayesian inference via…

Generic statements are a fundamental linguistic tool for efficiently passing along information. Yet they can leave a lot unsaid, such as how broadly they apply. In this dissertation, I examine how generic statements work as a pedagogical tool. To do so, I use the esport "League of Legends" as a naturalistic experimental setting in which…

Intro. A full account of speech perception requires explaining how listeners organize the acoustic signal into speech objects (perceptual organization) and how listeners use their memory for language to impart meaning to the speech objects (linguistic memory). Traditionally these mechanisms have been investigated separately, and thus theorized as…
