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…

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)

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)
