Discrete Trial Training (DTT) is a structured behavioral teaching method used in Applied Behavior Analysis (ABA) therapy to help individuals with autism spectrum disorder learn and acquire skills.
FREMONT, CA: Discrete Trial Training (DTT) is a structured behavioral teaching method used within Applied Behavior Analysis (ABA) therapy. It involves breaking down complex skills into smaller, discrete steps and teaching each step individually. This systematic approach promotes effective learning and skill acquisition in individuals with autism spectrum disorder (ASD) and other developmental disabilities.
DTT follows a structured and consistent approach, starting with presenting a clear and concise stimulus or instruction by the therapist. If necessary, the therapist provides a prompt to guide the child's response, such as pointing to the correct object. The child then attempts to respond to the stimulus, and the therapist gives immediate feedback based on the child's response. Positive reinforcement, like praise or a preferred item, is given for correct responses, while corrective feedback, such as identifying an incorrect response, is provided when needed. A brief pause, known as the inter-trial interval, follows each trial to allow the child to process the information.
The benefits of DTT include effective skill acquisition in areas such as language, motor skills, social skills, and daily living activities. Its structured format offers predictability, helping children understand expectations and feel secure. DTT also allows for precise data collection, enabling therapists to track progress and make necessary adjustments, and it can be individualized to meet each child's specific needs and learning style.
Recent advancements in DTT have focused on incorporating its principles into natural learning environments to promote the generalization of skills, emphasizing early intervention for better outcomes, and combining DTT with other ABA techniques like pivotal response training and incidental teaching. Ethical considerations, such as ensuring respectful and sensitive implementation, remain crucial.
