Applied Behavioral Analysis therapy, or "ABA therapy," is a treatment for autism and related conditions that emphasizes practice and repetition to overcome undesired behaviors. This treatment is empirical in using "direct measures of performance that tell us whether a child is making progress" and it is "systematic in that when we look at what things in the environment are likely to cause certain behaviors to occur, we arrange them in a systemic way that increases the likelihood certain behaviors occur."
ABA therapy uses rewards ("consequences") in order to promote desired activities, such encouraging the child to interact more with others.
ABA therapy is criticized by some for being robotic in nature, but supporters of the therapy explain that practice has value. ABA therapy does not address or cure the underlying causes of the autism.
