One of the most common problems faced by autistic children is sensory integration problems related to the challenges of developing social cognition. This research aims to establish the causal effect of sensory motor at home and its role in enhancing the social cognitive development of preschool children with autism spectrum disorder. Considering the difficulties of autistic children in the sensory processing and reciprocal social interaction domains, the active early intervention introduced in a familiar home environment has great potential to promote the development and improvement of the key cognitive and social skills. This qualitative research will involve interviewing parents of autistic children between the ages of three to six years. The researchers will identify the range of interesting and efficient sensory motor activities that are already taking place in the home environment and then analyse how these actions affect the social cognition development of the children in a more detailed manner. This research will provide a better perspective on the use of home-based sensory motor practices by providing empirically generated information in the process of facilitating social cognition. It can then be used to directly develop more accessible, convenient, and parent-friendly ways of the early intervention stage, enabling families to actively enhance their child's development in all areas beyond clinical environments and provide significant insights for stakeholders in the autism community, such as parents, educators, and therapists.
