This article presents an experimental investigation of kinematics of verb sign production in American Sign Language (ASL) using motion capture data. The results confirm that event structure differences in the meaning of the verbs are reflected in the kinematic formation: for example, in the telic verbs (throw, hit), the end-point of the event is…

Three studies are presented in this paper that address how nonsigners perceive the visual prosodic cues in a sign language. In Study 1, adult American nonsigners and users of American Sign Language (ASL) were compared on their sensitivity to the visual cues in ASL Intonational Phrases. In Study 2, hearing, nonsigning American infants were tested…

Spoken languages are characterized by flexible, multivariate prosodic systems. As a natural language, American Sign Language (ASL), and other sign languages (SLs), are also expected to be characterized in the same way. Artificially created signing systems for classroom use, such as signed English, serve as a contrast to natural sign languages. The…

While visual signals that accompany spoken language serve to augment the communicative message, the same visual ingredients form the substance of the linguistic system in sign languages. This article provides an analysis of visual signals that comprise part of the intonational system of a sign language. The system is conveyed mainly by particular…

The eyebrows are used as conversational signals in face-to-face spoken interaction (Ekman, 1979). In Sign Language of the Netherlands (NGT), the eyebrows are typically furrowed in content questions, and raised in polar questions (Coerts, 1992). On the other hand, these eyebrow positions are also associated with anger and surprise, respectively, in…

Introduces an issue of the journal containing articles that investigate candidate components of a prosodic system in sign languages, within the context of particularly relevant issues raised in spoken language research. (Author/VWL)

Focuses on the interaction of phonology with syntax, and to some extent, with meaning in a natural sign language. Adopts a theory of prosodic phonology, testing both its assumptions, which had been based on data from spoken language, and its predictions on the language of the Deaf community in Israel. (Author/VWL)

Three experimental techniques that can be used to investigate the gradient of discrete nature of intonational differences, the semantic task, the imitation task, and the pitch range task are discussed and evaluated. It is pointed out that categorical perception is a sufficient but not a necessary, property of phonological discreteness. (Author/VWL)

Individual signs were presented to deaf fluent signers both in context and without context. Within context, signs were isolated sooner, perfect confidence in the response was reached sooner, and a narrowing-in process was found that was both semantic and phonological. Current spoken-word-recognition models could be modified to reflect…

Focuses on phrasal prominence in American Sign Language (ASL). Reviews the marking of stress and phrase boundaries in ASL, and discusses prominence assignment at the phrasal level, with brief mention of lexical stress. (Author/VWL)

Describes how a laboratory phonologist might investigate three issues in the analysis of the prosody of signed languages: the internal structure, if any, of the signed syllable, the realization of lexical and phrasal prominence, and the marking of edges. Proposes to investigate the internal structure of the syllable by adapting psycholinguistic…

Reviews research from the fields of cognitive neuroscience and psycholinguistics, comparing spoken and signed language by looking at data concerning either cortical representations or early acquisition. (Author/VWL)

Presents two studies that explore facial expression production in deaf signers. An experimental paradigm uses chimeric stimuli of American Sign Language linguistic and facial expressions to explore patterns of productive asymmetries in brain-intact signers. (Author/VWL)

Researchers comparing the signing of deaf early and late learners of Swiss German Sign Language were struck by the difference in the production of signs by two groups of signers. Specifically that the signing of early learners was easier to watch and understand, because it was more rhythmic. Analyses were made of temporal aspects of the production…
