| Abstract: | In the present study we assessed the effect of a multifaceted program for ward staff members, which was intended to have severely/profoundly mentally retarded individuals improve their use of communicative gestures. The program consisted of instruction, verbal and visual (publicly posted) graphic feedback. There were two categories of dependent variables. The first category involved the number of gesture prompts by staff, number of unused opportunities to evoke gestures, and number of consequences given for gestures. The second category involved handicapped individuals' number of prompted gestures, number of spontaneous gestures, and number of different gestures. Results show that the program was effective with regard to all these variables. Changes in the number of spontaneous gestures were especially remarkable, as this variable had not been influenced directly. Follow-up data underline the effectiveness of the program. |
