The intervention group will receive both occupational therapy and virtual reality.a) Occupational Therapy: The basis of OT intervention consisted of activities requiring increased attention, behavioral regulation, organizational skills, multiple cognitive skills, and motor skills.

Virtual Reality: The virtual reality system consists of a camera, television, Eye Toy Play CD and Play Station 2. It is based on the principle of capturing movements represented in a virtual environment (Gatica and Méndez, 2014). In the Eye Toy system, individuals can see themselves on the screen through the camera. In this way, the person constantly interacts with the movements and challenges brought by video games. We can simply call the Eye Toy system a webcam with a motion sensor and microphone. The individual's position in the game is determined on the screen and can perceive the person according to the movements he/she exhibits.

The main skills required by the games are; target-based movement, visuomotor skills, praxis and thinking process skills.

The Dynamic Occupational Therapy Cognitive Assessment (DOTCA-Ch): It was developed to evaluate the cognitive functions of children between the ages of 6 and 12. It includes 22 subtests in 5 cognitive areas; orientation, spatial perception, praxis, visuomotor construction and thinking operations. There is a structured 5-stage scoring system for each subtest. The purpose of the assessment is to identify the child's strengths and deficiencies in different cognitive areas, to measure learning potential and to identify the child's thinking strategies using dynamic procedures. The practice time is approximately 1½ hours
