From RJ Cooper & Associates:
A switch or touch activity that helps learners to know when to activate and when NOT to activate the switch/iPad. Music is the key positive reinforcer with animated scenes of life situations as the graphic elements. Many Skinner/behavioral prompts/features are built in, such as "Wait," "Stop, please," positive reinforcement, motivating operations, and others. Included is the ability to import your own music!
