Focused on student-initiated interactions and is primarily used to teach communication

One of the hallmarks of Incidental Teaching is setting up the environment to encourage child-initiated conversations and activities by placing highly preferred items out of reach, but in sight.  This requires the child to initiate an interaction by mading (asking for the item).  Mands are under the control of motivational operations.  Positive reinforcement comes in the form of praise coupled with receiving the item being asked for.
