Abstract:

Otizm spectrum disorder (OSB) is defined as a neurological disorder that appears in individuals in early childhood, leads to limited interests and streotype/disadvantaged behaviors in individuals, restricts individuals' social interaction and communication skills, negatively affects their socialization and alienates them to the external world. Autism causes individuals to show problem behavior in many ways. Reducing problem behavior in autism individuals is only possible through special training. Providing problematic behaviors such as leaving the task in half, showing streotype behaviors, having limitations in social interaction and communication while trying to fulfill a task of autism individuals is done only through special training using certain methods or techniques. This study was conducted with the aim of revealing the effect of joint use of continuous and interim reinforcement on the enhancement of the task completion behavior of an autistic individual. The research was carried out with the ABAB model from a single comparable research model. The study was conducted by a five-year-old man with autism. The study used indirect and direct methods of determining the student's preferred reinforcements. The study found that when arrangements were made in accordance with the development and preferences of an autistic individual, when necessary reinforcements were used, the individual’s task completion behavior increased. This study found a conclusion that continuous and interim reinforcement leads to an increase in the participant’s task completion behavior and a positive effect on the performance of the task. In the research, it is recommended that this subject is aimed at several participants for advanced research and that the research is conducted using another teaching model in practice.
