Recent research shows that deaf signers show increased behavioral and neural sensitivity to certain types of movement, such as biological motion, human actions, and signing avatars. However, other work suggests that in deaf signers exposed to signed language before age five, the mirror mechanism has minimal involvement during the perception of…

Studies have reported a right visual field (RVF) advantage for coherent motion detection by deaf and hearing signers but not non-signers. Yet two studies [Bosworth R. G., & Dobkins, K. R. (2002). Visual field asymmetries for motion processing in deaf and hearing signers. "Brain and Cognition," 49, 170-181; Samar, V. J., & Parasnis, I. (2005).…

Investigates the psychological representation of visual-gestural languages from a cross-linguistic perspective. The perception of signers of American and Chinese Sign Languages is analyzed. (27 references) (Author/VWL)

This paper, in reviewing four different studies, discusses the influence of some basic parameters or aspects of a sign on the accuracy of perceiving that sign. This information can aid the teaching of signs to the mentally retarded, the autistic, the cerebral palsied, and the hearing adult. A series of studies was conducted in which the aim was to…
