[Air-L] research of technology use among people with intellectual disabilities

Hi, I have been seeking research of technology use among people with intellectual disabilities (ID). Especially those research which concern where, how much and for which purpose people with ID use computers and Interent. I have found a couple of research (Parette & VanBiervliet 1992; Wehmeyer's 1998 &1999; Carey, Friedman, Bryen 2005). I would appreciate if someone could tell me if there are another relevant research. Thanks, Eija ////
