Being able to communicate one's wants and needs is an essential step in typical language development. However, children with diagnosed language delays, which constitute approximately 5-10% of children under three years, may reach this step later than typically developing children. According to Rossetti (2001), communication skills are the most…

Kenyan Sign Language (KSL) is a thriving national sign language used by tens of thousands of signers in Kenya, and which emerged out of two deaf schools in western Kenya in the early 1960s. In this thesis, I provide a thorough description and analysis of the basic phonological components of the KSL lexicon used in the southwestern region of Kenya…

In my dissertation, I examine four notation systems used to represent hand configurations in child acquisition of signed languages. Linguists have long recognized the descriptive limitations of Stokoe notation, currently the most commonly used system for phonetic or phonological transcription, but continue using it because of its widespread…

Deaf and hard of hearing (D/hh) students face academic challenges in the post-secondary setting due to low literacy skills and academic barriers. However, despite these challenges, little attention has been focused on mainstream faculty who teach D/hh students. This study investigated perceptions of mainstream faculty at the post-secondary level…

The language-based analogical reasoning abilities of Deaf children are a controversial topic. Researchers lack agreement about whether Deaf children possess the ability to reason using language-based analogies, or whether this ability is limited by a lack of access to vocabulary, both written and signed. This dissertation examines factors that…

The aim of this study was to identify and implement research-based practices in reading comprehension that would enable deaf and hard-of hearing adolescents to monitor their comprehension actively to increase the reading level beyond fourth grade. Making meaning out of teachers' and students' reading comprehension experiences through their…

The purpose of this dissertation was to examine the development and importance of fingerspelling among young Deaf children of Deaf parents for communication, learning about language, and pre-literacy in their natural home environment. The rationale was to examine how Deaf parents use fingerspelling with their young Deaf children during…

Using an autoethnographic approach, this dissertation explores the path taken by a person who serves a unique population of individuals--people who not only have more than one disability, but in addition, are unable to communicate using verbal (spoken) speech. Starting with a recap of the history of the use and subsequent oppression of American…

In this dissertation, I examine the nature of object marking in American Sign Language (ASL). I investigate object marking by means of directionality (the movement of the verb towards a certain location in signing space) and by means of handling classifiers (certain handshapes accompanying the verb). I propose that object marking in ASL is…

This dissertation is an examination of gesture in two game nights: one in spoken English between four hearing friends and another in American Sign Language between four Deaf friends. Analyses of gesture have shown there exists a complex integration of manual gestures with speech. Analyses of sign language have implicated the body as a medium…

Most postsecondary American Sign Language programs have an inherent connection to their local Deaf communities and rely on the community's events to provide authentic linguistic and cultural experiences for their students. While this type of activity benefits students, there is often little effort toward meaningful engagement or attention to…

This dissertation will show how linguistic description and an Autolexical account of the bound verb root [take] shed a light on the nature of complex verb constructions in American Sign Language (ASL). This is accomplished by creating a new ASL Verb Complex Model unifying all verbs into one category of VERB. This model also accounts for a variety…

This dissertation examines six different types of noun phrases that commonly occur in American Sign Language. These noun phrases all include at least a head noun and one of four signs resembling a pronoun. Videos of natural ASL discourses are gathered, multiple instances of the six types of noun phrases are identified, and their meanings are…

The broad application domain of the work presented in this thesis is pattern classification with a focus on gesture recognition and 3D hand pose estimation. One of the main contributions of the proposed thesis is a novel method for 3D hand pose estimation using RGB-D. Hand pose estimation is formulated as a database retrieval problem. The proposed…

Students who are deaf and use sign language frequently have language delays that affect their literacy skills. Students who use American Sign Language (ASL) often lack fluent language models in both the home and school settings, delaying both the development of a first language and the development of literacy in printed English. Mediated and…
