ADVERBIAL MORPHEMES IN TACTILE SIGN LANGUAGE: Deaf-Blind Interpreting
This chapter investigates adverbial use in tactile American Sign Language (TASL) using a linguistic case study of a conversation between two adults with Usher syndrome Type I. The participants were videotaped during a 50-minute dialogue. The study found that the signers used tactile components (such as holds, tenseness in hands, and added signs) to make up for visual nonmanual signals that convey meaning in ASL. Specific ways in which they expressed adverbials of various types are presented in tables. The author concludes that there is grammatical variation between visual and tactile ASL.
