Second language acquisition (SLA) research offers valuable insight on how languages are learned and how they coexist and influence each other. Sign language learners offer unique perspectives on SLA, allowing researchers to test theories that are otherwise constrained by access to only one modality. Current literature on sign language learning…

Sign language interpreters work with a variety of consumer populations throughout their careers. One such population, referred to as "emergent signers," consists of consumers who are in the process of learning American Sign Language, and who rely on interpreters during their language acquisition period. A gap in the research is revealed…

Across a diverse range of languages, children proceed through similar stages in their production of causal language: their initial verbs lack internal causal structure, followed by a period during which they produce causative overgeneralizations, indicating knowledge of a productive causative rule. We asked in this study whether a child not…

The primary goal of this dissertation is to investigate the relationship between Universal Grammar and the properties that Universal Grammar constrains, by investigating how language is created/acquired. The framework proposed in this dissertation provides us with tools for predicting what will and will not appear in linguistic systems of…

This article puts forward a solution to the impending shortage of culturally and linguistically competent interpreters: the education of heritage signers as heritage language learners. It examines the current landscape of American Sign Language (ASL) as a course of study and the difficulties heritage signers report when they begin learning ASL. In…

The papers in this special issue of "Language and Cognitive Processing" on the neural bases of language production illustrate two general approaches in current cognitive neuroscience. One approach focuses on investigating cognitive issues, making use of the logic of associations/dissociations or the logic of neural markers as key investigative…

Language is proposed to have developed atop the human analog of the macaque mirror neuron system for action perception and production [Arbib M.A. 2005. From monkey-like action recognition to human language: An evolutionary framework for neurolinguistics (with commentaries and author's response). "Behavioral and Brain Sciences, 28", 105-167; Arbib…

In 1981, Swedish Sign Language gained recognition by the Swedish Parliament as the language of deaf people, a decision that made Sweden the first country in the world to give a sign language the status of a language. Swedish was designated as a second language for deaf people, and the need for bilingualism among them was officially asserted. This…

Examines the relationship between sign language and gesture in language acquisition. Specifically, the question is asked, are sign language and nonlinguistic gestures treated differently by infants acquiring a sign language? The answer is found in reexamining data concerning two deaf children learning American Sign Language (ASL). The data…

Linguistic descriptions of sign languages are important to the recognition of their linguistic status. These languages are an essential part of the cultural heritage of the communities that create and use them and vital in the education of deaf children. They are also the reference point in language acquisition studies. Ours is exploratory…

Discoveries about the acquisition of American Sign Language (ASL) by deaf children are reviewed. Current research shows that ASL has developed as a fully autonomous language with complex organizational properties not derived from spoken language. Like spoken languages, ASL exhibits formal structuring at two levels and similar organizational…

Four keynote papers, presented at an international conference on sign language research, discussed general linguistic issues of sign language, psycholinguistics, sociolinguistics, and language acquisition. (CB)

Seeks to determine how consistently a sample of hearing mothers using simultaneous communication to their deaf children signed what they said. Data indicate that the difficulty of simulaneously signing and saying the message predisposes the mothers toward inconsistent simplification in the signed input which may or may not be helpful for language…

Finds that students in prekindergarten classes who received sign instruction tested significantly higher on the Peabody Picture Vocabulary Test than students in prekindergarten classes who did not receive sign instruction. Suggests that simultaneously presenting words visually, kinesically, and orally enhances a child's vocabulary development. (SR)

Discusses recent research that has examined the early stages of language development in signed and spoken languages as well as suggestions that there is an advantage for the acquisition of signed languages. Specific attention is focused on whether or not a single timing mechanism underlies early milestones in the acquisition of both vocabulary and…
