The purpose of this project is to identify a problem behaviour in a child with ASD (autism spectrum disorder) and use evidence-based practice to reduce the behaviour and teach a replacement behaviour. The behaviour identified is throwing and swiping materials during tasks, and the function maintaining this behaviour is escape from the task. Therefore, this applied study attempted to evaluate a procedure commonly used to decrease problem behaviours of the child with autism spectrum disorder by implementing extinction procedure and differential reinforcement for alternative behaviour. With this study, we alter the environment by reinforcing appropriate alternative behaviours and placing problem behaviours (throwing/swiping items, non-compliance) on extinction. Sessions were conducted for the participant 5 days in a week. A total of 14 sessions were organized including 3 baseline sessions. And the duration of the session was 30 minutes, which was divided into 15-15 minute’s conditions to calculate data. The child behaviour was scored during the sessions by calculating the occurrence and non-occurrence of challenging behaviour per session by partial interval recording on data sheet. The behavioural problem in child was gradually decreased over 14 sessions. Intervention ended for the target behaviours when problem behaviour was decreased and the child started responding to the task.
