This study was conducted to determine the effectiveness of using the high-tech speech-generating device with Proloquo2Go app to reduce echolalic utterances in a student with autism during conversational speech. After observing that the iPad device with several apps was used by the students and that it served as a communication device, language…

Past studies have identified the function of SELF as a canonical reflexive pronoun in American Sign Language (ASL). This study examines the use of SELF with fifteen hours of naturalistic ASL discourse framed by the cognitive-functionalist approach. The analysis reveals that the category of SELF is expressed in three phonological forms and exhibits…

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 frequency-lag hypothesis proposes that bilinguals have slowed lexical retrieval relative to monolinguals and in their nondominant language relative to their dominant language, particularly for low-frequency words. These effects arise because bilinguals divide their language use between 2 languages and use their nondominant language less…

In a variety of contexts, deaf individuals often must navigate multiple societal, psychological, and physical barriers. It is frequently proposed that role models meet an important need for successful navigation in such contexts. The present article, a research synthesis, explores available literature on role models for deaf individuals, drawing…

The present article introduces a special issue of the "American Annals of the Deaf." Students who are d/Deaf or hard of hearing and come from homes where a language other than English or American Sign Language is used constitute 19.4%-35.0% of the U.S. d/Dhh population (Gallaudet Research Institute, 2013). The authors propose moving…

Arbitrary symbolism is a linguistic doctrine that predicts an orthogonal relationship between word forms and their corresponding meanings. Recent corpora analyses have demonstrated violations of arbitrary symbolism with respect to concreteness, a variable characterizing the sensorimotor salience of a word. In addition to qualitative semantic…

Children typically acquire their native language naturally and spontaneously at a very young age. The emergence of early grammar can be predicted from children's vocabulary size and composition (Bates et al., 1994; Bates, Bretherton & Snyder, 1998; Bates & Goodman, 1997). One central question in language research is understanding what…

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…

Information about cancer, the disease that kills more Americans than any other except heart disease, is essential. In some ways, information is our first line of defense. It allows us to identify individual risk factors, to note when a problem means we should see a professional, and to avoid activities that might put us at risk. However,…

This dissertation describes the features of co-speech gestures of English/ASL bilinguals and addresses three main questions: 1) How do English/ASL bilinguals gesture differently than non-signers? 2) How do native ASL/English bilinguals gesture differently than non-native English/ASL bilinguals? 3) Do English/ASL bilinguals gesture differently to…

Child First is a national campaign to ensure that deaf children have their right to language recognized and fulfilled regardless of which educational method is specified in the Individualized Education Program (IEP). Whether the child's family embraces American Sign Language (ASL), speech reading, a system of signs that encodes English, or a…

In recent years, researchers have turned their attention to the cognitive impact of bilingualism, and the benefits of using two languages have become increasingly apparent. Children raised in bilingual families exhibit stronger awareness of the style and tone of language, stronger cognitive development, and higher levels of reading skill than…

The widespread adoption of smartphones and tablet computers have enabled the rapid creation and distribution of innovative American Sign Language (ASL) and written English bilingual ebooks, aimed primarily at deaf and hard-of-hearing children. These sign-print bilingual ebooks are unique in how they take advantage of digital platforms to display…

In this paper we examine the theory of the structure of signs that grew from Stokoe's (1965) proposals. We begin by examining argument for the structural simultaneity of signs by examining claims about how signs contrast and how cheremes function. Historically, such discussions have involved three claims: (1) that signs are composed of a single…
