This study examined the effectiveness of two procedures, a visual cue and performance posting, to modify the use of sign language by psychiatric technicians. The visual cue was first introduced alone, then paired with performance posting to encourage staff use of sign language with the developmentally disabled children in their charge. Application of the visual cue alone produced little change in staff sign useage. The visual cue plus performance posting condition increased staff use of sign language during mealtimes. Four weeks of follow-up data indicated that the use of sign language remained at a level well above baseline.
