Will Play Attention Work for Younger and Older Teenagers?

Will these technologies work for younger and older teens? And we actually have questions around, could this be helpful for adults as well? So, play attention is for adults. Most of the other ones are really more focused on younger kids. The biggest issue that I think we're going to see with all this stuff - how do we get this stuff to generalize? How do we get a closer or a near transfer rather than a far transfer?"
