What does DTT stand for in ABA practice?

Discrete Trial Training, commonly abbreviated as DTT, is a structured teaching method used in Applied Behavior Analysis (ABA) that involves breaking down complex skills into smaller, manageable components. This technique is especially effective for teaching individuals with autism and other developmental disorders, as it provides clear and consistent opportunities for learning.

DTT consists of a series of trials in which a specific behavior or skill is targeted. Each trial usually follows a specific format that includes a prompt or instruction, the individual's response, and any reinforcement provided for correct responses. This structured approach allows for precise measurement of behavior and effective data collection over time, which is essential for tracking progress and making informed adjustments to interventions.

The use of DTT is beneficial because it allows practitioners to systematically teach new skills while minimizing distractions, making it easier for learners to focus and respond. Reinforcement plays a critical role in DTT, as it encourages the repetition of desired behaviors, aiding in the effective acquisition of skills.
