• Previous studies have suggested that experience of sign language has an affect on visuospatial cognitive ability. Because the production and perception of hand postures are important elements of sign language it has been suggested that the cognitive ability of deaf signers for hand postures is specialized in some way. This study investigated the ability for production of mental images of hand postures by deaf signers and hearing non-signers. The participants were required to imagine various hand postures, and to judge whether the hand postures they imagined would be physically natural or not. It has been suggested that it takes longer to imagine unnatural postures of parts of the body than natural postures because of biomechanical constraints. However, the present results have indicated that the naturalness of postures did affect the reaction time of the hearing group but not of the deaf group. These results have suggested that an experience of sign language may alter cognitive processing of hand postures.
