ABA is a methodology that can be applied everywhere, with anyone, at any time.
Behaviors are strengthened by positive reinforcement and diminished by non-reinforcement or replacement by something else. It is effective because you constantly monitor the program by collecting objective data and analyzing it - then modify interventions based upon the data. Another myth is that ABA only works for certain kids. It doesn't take away from the child's personality. When done correctly, ABA will NOT turn your child into a robot but it WILL maximize learning by teaching HOW to learn.
