“…When the topics of studies carried out with siblings are examined, the very first studies in particular have focused topics such as using behavior modification techniques for teaching academic skills to siblings with ASD (Schreibman, O'Neill, & Koegel, 1983), teaching independent living and academic skills (Swenson-Pierce, Kohl, & Egel, 1987;Tekin & Kircaali-İftar, 2002) and providing them with leisure activities (Cash & Evans, 1975). When Celiberti and Harris (1993) evaluated the studies carried out with siblings, they emphasized the importance of practices regarding the education of social interaction behavior as well as play activities in these practices, especially when the sibling with ASD is younger. These researchers taught techniques to three typically developing siblings between the ages of seven and ten.…”
