In my mod/severe class this year I have a low student with autism who is non verbal. Whenever an adult approaches, or a direction is given, the student drops to the floor and let's their legs go limp. If we attempt to have the student follow through with a direction with physical promoting, they will continue to let their body go limp and it's pretty physically taxing to try to do anything. It seems that even when highly motivating edibles or reinforcers are presented, the student still drops to the floor. What do you do when a student drops? Wait them out until they get up? Follow through with a physical prompt? What type of protocol can we put in place to eliminate this behavior?
