Describes single finger sign contact in data from ten different sign languages. The relative frequencies of signs using each of the four possible fingers are examined. Proposes distinctive features to explain the differences in frequency and use of these handshapes in sign languages in general. (Author/LMO)

Handshapes with single finger extension are examined in data from 10 sign languages: American, Australian, British, Finnish, French, Japanese, Providence Island, Rennell Island, Indian, and Swedish. It is concluded that a theory of marking can be developed along the same lines as for spoken language, with only the physiology differing. (Author/MSE)
