Discrete Trial Training (DTT) is a structured teaching method often used in Applied Behavior Analysis (ABA) to help individuals, particularly those with autism, learn new skills. It involves breaking down skills into small, manageable parts and teaching them through repeated practice. Each trial consists of a clear instruction, a response from the learner, and immediate feedback. DTT typically follows a three-step process: the teacher presents a prompt, the learner responds, and the teacher provides reinforcement or correction. This method allows for consistent tracking of progress and helps to reinforce desired behaviors, making it effective for skill acquisition and behavior modification.
