Neuroscientist Sandra Aamodt, the author of Welcome to Your
Child’s Brain, praises Zamzee’s focus on physical activity instead
of weight. She cautions, however, that research has revealed that
intrinsic motivation outlasts extrinsic rewards. (Intrinsic motivation
comes from inside an individual rather than from external rewards,
such as money or grades.) With that in mind, Zamzee’s developers
have been testing multiple methods for motivating children.
They have found that combining virtual (electronic) and monetary
rewards can be successful.
