Abstract
In this case study, for training to achieve a self-reliant life, the acquisition of social skills through a package technique of verbal instruction, guidance such as by prompting, modeling, and self-reinforcement by audio-visual analysis was applied to a moderately retarded adult. Locking-up skills and cooking skills were designated as target behaviors. A multiple baseline design across behaviors was used as the experimental desigin. Training was divided into three phases : customarization ; shaping ; establishment and spontaneousness, and post checks and generalization tests were conducted. Gradual shaping was attempted by repeatedly conducting behavioral assessments of a client in a situation setting simulating casual life. It was found that, of actions that had never happened in the baseline period, locking-up skills showed a 100 percent occurence rate. Cooking behavior skills also achieved the target criteria. This effect was retained in post check and generalization tests conducted 3-9 months later.
