Description: Also called Greenspan Method. In Floor Time, the adult aims to engage the child with autism spectrum disorder (ASD) by following his/her lead during play activities that capture the child’s interest. The adult seeks to extend or elaborate on the child’s activities. For example, if the child wants to line up cars in a row, the parent or service provider may playfully intrude in this activity (e.g., moving one of the cars or blocking a car and asking where it’s going). Floor Time is usually provided by parents under the direction of psychologists. However, it may be an intervention strategy used by professionals in other disciplines such as speech therapy or special education.
