Abstract
This study introduces the reasoning behind a proposed paradigm change in sign-language studies that shifts attention from language-centered research focused on grammar and syntax to communication-centered research focused on the use of language in daily life. This paper does not address social issues related to deaf education and disability services, but rather clarifies how native signers communicate with one another during conversations. I will attempt to integrate methodologies derived from gesture studies (e.g., the concept of a gesture unit) and conversation analysis (e.g., the concept of a turn-taking system) to develop a new multimodal methodology for the analysis of sign-language conversations. I expect this methodology to contribute to areas such as the investigations of the synchronicity between the signing of words and the performance of mouth movements, and the mechanisms underpinning overlap in sign-language conversations. After presenting a detailed explanation of the transcription and annotation of the data obtained in sign-language conversations, I will introduce two case studies related to turn-taking and overlap in conversation. I also anticipate that this approach will motivate individuals without previous exposure to deaf people and sign language to become more familiar with both.
