This study applied a multiple baseline across-behaviors design and was divided into four successive phases: baseline, intervention, generalization and maintenance phase. The participants were three adults with severe intellectual disability selected purposely. The independent variables of this study were picture fading strategies; the dependent variables were times of correct responses of participants in every assessment of intervention, generalization and maintenance phase. The data collected were analyzed by curves, visual analysis and the C statistics. Based on the findings, the researcher summarized the conclusions as follows: 1. Picture fading strategies could promote the immediate effects of functional vocabulary learning of adults with severe intellectual disability. Base on the analyses by visual analysis and the C statistics, every participant performed significantly better in intervention phase than in baseline phase. 2. Picture fading strategies are effective in generalization effects of functional vocabulary learning of adults with severe intellectual disability. Base on the analyses by visual analysis and the C statistics, every participant performed equally in generalization and intervention phase. 3. Picture fading strategies are effective in maintenance effects of functional vocabulary learning of adults with severe intellectual disability. The participants’ performance declined slightly from generalization phase to maintenance phase according to visual analysis, but the decrease was not significant according to the C statistics.
