This study aims to investigate the perception of phonological, grammatical, and semantic structures by 8 children (age range: 8;2-9;5) with developmental language disorders (DLD). Another 8 age-matched (age range: 8;4-10;0) typically developing (TD) children served as controls. The results demonstrated that children with DLD had lower performance…

Purpose: This study aims to examine the associations of phonological, lexical, and grammatical skills within and between languages in Mandarin-English bilingual preschoolers. Method: Sixty-three Singaporean Mandarin-English bilingual children aged 3-5 years were assessed for articulation, receptive vocabulary, and receptive grammar using…

Individual speakers' speech patterns differ from one another, despite presumably similar language input. What are the sources of this individual variability? In this dissertation, I explore sources of individual differences in pronunciation of coronal obstruents (/s/, /t[superscript h]/, /c[superscript h]/, /c/) at the ends of nouns in Korean.…

Background: The most common cause of aphasia is a left middle cerebral artery stroke affecting the left perisylvian region of the brain. The perisylvian region is critical for supporting phonological processing, and damage to this region results in difficulty with retrieving and manipulating speech sounds. The impact of weakened phonology has been…

Paradigms with conflicting data patterns can be difficult to learn, resulting in acquisition error. In this dissertation, I look at how paradigms are reanalyzed over time to gain insight into the factors that influence morphophonological learning. Existing models of morphophonology (e.g. Hare & Elman 1995; Albright 2002b,a, 2010) predict…

The purpose of this study was to determine the most prevalent African American Language (AAL) phonological and grammatical features in slavery- and Civil Rights-themed children's literature. Seventy-six books were initially selected to determine if they used AAL in dialogue or in narration. Of the 76 books, only 39 included AAL. The 39 books were…

In this dissertation, I establish a research program that uses computational modeling as a testbed for theories of phonological learning. This dissertation focuses on a fundamental question: how do children acquire sound patterns from noisy, real-world data, especially in the presence of lexical exceptions that defy regular patterns? For instance,…

The Arabic traditional grammar as well as Chomsky's mainstream theory may not be able to provide a good analysis of some fixed Arabic phrases. The challenge of such data directly stems from the fact that the general syntactic rules assumed by the two opposing theories cannot explain the syntactic and the semantic aspects of the fixed Arabic data.…

Human language is an incredibly rich yet incredibly constrained system. Learning and generalizing these systematic constraints from small, sparse, and underspecified data presents a fundamental inference problem. Therapidity and ease by which humans learn these constraints has made this a foundational study in cognitive science, linguistics, and…

Friday sermons portray patterns of lexical cohesion which can demonstrate how effective communication is achieved. This study proposes a model of lexical cohesion that fits the spoken discourse of Friday sermons in the United Arab Emirates (UAE). To that end, a corpus of 25 sermons was analyzed to identify patterns of cohesion and show the impact…

Yamdena is an Austronesian language of eastern Indonesia. Although many language materials are available, the language has received very little scientific attention. In this article, I present the Yamdena corpus, which includes glossed legacy materials and original fieldwork. I also give an up-to-date introduction to Yamdena grammar, sketching its…

This paper examines the understudied phenomenon of consonant gemination in the pronunciation of English among Levantine Arabic learners of English (LA learners). The very few studies that touched on gemination among LA learners attributed gemination to spelling in the target language (English). This study challenges this analysis and demonstrates…

The aim of this study is to analyze spoken linguistic features of three-minute startup pitches. Linguistic features analyzed included discourse markers, dysfluency, modality, numeral phrases, pronouns, reduced forms, repetitions, rhetorical questions, vague expressions, and vocatives. The corpus is comprised of 92 startup pitches delivered in real…

Purpose: The experiment reported here compared two hypotheses for the poor statistical and artificial grammar learning often seen in children and adults with developmental language disorder (DLD; also known as specific language impairment). The "procedural learning deficit hypothesis" states that implicit learning of rule-based input is…

Each language has its unique way to mark grammatical information such as gender, number and tense. For example, English marks number and tense/aspect information with morphological suffixes (e.g., -"s" or -"ed"). These morphological suffixes are crucial for language acquisition as they are the basic building blocks of syntax,…
