According to this article: First-graders have more behavior problems on the days that they are exposed to caffeinated colas than on the days that they have caffeine-free drinks.

Exposure to caffeinated cola drinks impaired children's learning ability by causing restlessness, hyperactivity, and inattention. On the days that the children were drinking caffeinated drinks, their Connors scores increased an average of 5.5 points compared to the days that they were only drinking caffeine-free drinks.
