This project aims at investigating how effective virtual reality is in manipulating and eventually training time perception for children with learning and/or behavior disorders. The interconnectivity of multiple brain regions is needed for time perception. Small dysfunctions in these brain regions may cause time perceiving problems. Likewise, children with attention deficit hyperactivity disorder (ADHD) appear to have comparable dysfunction in time orientation. However, the time perception can be trained in their early ages. In addition, research confirms the effectiveness of virtual reality in improving the sequential time perception of children with mental retardation. This paper presents the theoretical and empirical framework that uses a virtual reality time simulation game for training time perception of children with ADHD.
