What is Discrete Trial Training?
Discrete Trial Training, or DTT, is an evidence-based training and teaching procedure for children with autism. It is an understandable, highly structured, proven, and straightforward component of an ABA (Applied Behavioral Analysis) program.
How does Discrete Trial Training work?
DTT works by giving the child a precise set of steps in an effort to change or redirect behavior. There are 3 components involved in each trial:
- Antecedent
- Behavior
- Consequence
In the first step of this ABC approach, a behavioral technician delivers an instruction – the Antecedent. Next, the child provides an appropriate response – a Behavior. Finally, the technician delivers a Consequence, which involves reinforcement, a positive response, or redirection.
How does DTT differ from other therapies?
Direct Trial Training breaks significant skills into smaller, teachable, “discrete” pieces. This strategy facilitates learning because it simplifies tasks. DTT gives the child many chances to hone skills as they receive positive reinforcement or rewards for appropriate responses. In contrast:
- Verbal Behavior Intervention teaches the child to communicate with “mands” using a technique called “errorless learning,” where prompts are immediately and repetitively delivered to elicit an appropriate response from the child.
- Pivotal Response Training guides children through the use of play-centered therapy to improve communication, behavioral, learning, and social skills. It utilizes “natural motivation” to reduce unwanted behavior, improve positive behavior, and develop language and communication skills, focusing on social interaction, cue responses, and self-management.
- Natural Environment Teaching uses the child’s motivation and follows his or her lead. In realistic settings, NET is a personality- and needs-based session with a loose, flexible structure.
DTT is an effective component of a comprehensive ABA treatment plan because it teaches a variety of skills, including naming and identifying pictures and objects, following directions, matching, and more. It is not intended to teach social, play, or communication skills. If you have any further questions please contact us and we’d be happy to help.
