No, the stimulants increase focus ability and attention for ADHDers. My son does notice a difference in his perkiness on or off vyvanse, but he also realizes that being perky doesn't necessarily equate to being able to focus and follow through. Motivation is more intrensic than focus and attention. I don't think it comes in pill form unfortunately.

If he's only taken the concerta once, it's a bit soon to really know how it will work for him yet. It may take a few weeks for it to settle in and for him to really know the end result.
