| Abstract: | In two studies, self-choking by a middle-aged man with mental retardation was controlled both directly and indirectly by positive procedures. In the first study, paced eating procedures were employed to control postmealtime rumination. The frequency of generalized self-choking increased from periods where meals were paced to periods in which meals were not paced and vice versa. In the second study, redirection of self-choking and reinforcement for responses other than self-choking (DRO) reduced the frequency of self-choking, with the procedures applied successively to a number of different environments, trainers, distances from the client, and DRO parameters. These procedures related to a substantial reduction in generalized self-choking measured in other environments at other times. |
