“…The use of simultaneous constructions to convey temporal information has been observed in a number of other sign languages, including ASL, British Sign Language, Danish Sign Language, Irish Sign Language, and Quebec Sign Language (Emmorey, 2002; Engberg-Pedersen, 1993, 1994; Leeson & Saeed, 2002; Liddell, 2003; Miller, 1994; Morgan, 2002; Rathmann, 2005). Simultaneous constructions may prove to be a sign language universal, taking advantage of the capacity for simultaneity in the manual modality, in contrast to the strict linearization required by vocal production (e.g., Emmorey, 1995; Padden, 1988; Perniss, 2007). While there is little developmental data on native signing children's acquisition of simultaneous constructions, this particular device appears to require considerable linguistic skill, since the signer must represent two referents or two events, one with each hand, and encode their locative or temporal relation to each other.…”
