PRT is highly focused on whatever motivates the child. These are delivered in a more natural and less structured way than DDT. Yes! Many of the effective early intervention approaches for autism are based on ABA principles, including the Early Start Denver Model (ESDM) and Pivotal Response Treatment (PRT). Are there other types of ABA that are effective for autism in addition to DTT? DTT was one of the very first interventions developed for autism and has extensive research supporting it. Many therapists have found DTT to be particularly effective for teaching skills to children with autism. After the child learns all his colors, the trainer might teach the child to say each color’s name. She would then move on to teaching yellow by itself, reinforce that skill, and then ask about both colors. She would ask the child to point to red and then reward the behavior. For a child, this might include a candy or small toy.įor example, a trainer teaching colors to a child might begin by teaching red. Along the way, trainers use tangible reinforcements for desired behavior. Systematically, the trainer teaches these skills one by one. So how is DTT different?ĭTT is a structured ABA technique that breaks down skills into small, “discrete” components. This relationship between the antecedent, behavior and consequence is what ABA is all about. Rewards and consequences can make a behavior more or less likely to happen again in the future. In fact, most parents use a form of “ABA” on a daily basis, for example, by giving a child a “time out” for hitting or putting on a favorite movie after a child finishes his homework. It’s also used to help those struggling with problem behaviors such as drug addiction. ![]() Beyond the field of autism, it’s widely used to help individuals develop positive behaviors – such as good study habits. You enjoyed a positive consequence for your behavior, and this increases the likelihood that you’ll again eat when hungry in the future!ĪBA applies this principle as an intervention to produce positive changes in behavior. It looks at behavior as a three step process: the antecedent (a cue or instruction), the behavior and the consequence.įor example, when you’re hungry (antecedent), you eat something (behavior) and then you feel better (consequence). ![]() So let’s tease the two apart.ĪBA applies the science of “behaviorism,” to bring about meaningful change in an individual’s actions. ![]() DTT is one of several types of teaching strategies that fall under the umbrella of ABA. Often times when people talk about ABA programs for children with autism, they are actually referring to DTT. There tends to be a lot of confusion between terms Discrete Trial Training (DTT) and Applied Behavioral Analysis (ABA). This week's "Got Questions?" answer comes from Lauren Elder, PhD, Autism Speaks assistant director of dissemination science.
