Memory in deaf signers and embodied cognition of sign languages

Abstract:  In the first half of this paper, the experimental investigations on memory and cognition in deaf signers are reviewed in order to reveal how deaf signers rely on sign-based coding when they process linguistic information. It is suggested that deaf signers tactically employ a set of originally separate memory strategies relying on multiple components of working memory. In the second half of this paper, the author shows possible factors that could contribute to a sign language advantage. It is indicated that deaf signers' cognitive activities are deeply rooted in the signers' interaction with the environment. Some concrete examples of Japanese Sign Language signs and their use are provided to support this hypothesis.
