What is the main characteristic of Discrete Trial Trainings?

Discrete Trial Training (DTT) is characterized primarily as a one-on-one instructional method that is planned and systematic. In DTT, learning occurs through a structured process involving clear and defined steps, typically including an antecedent (the instruction), a behavior (the child's response), and a consequence (reinforcement or correction). This method ensures that each trial is consistent and can be measured, making it an effective teaching strategy for individuals with developmental delays or autism.

The systematic nature of DTT allows for targeted teaching and repeated opportunities to practice skills until they are mastered. This structured approach contrasts with unstructured methods, which may lack the necessary guidance and repetition that DTT offers. Additionally, while DTT involves individualized instruction, it does not generally incorporate group activities, nor does it exclusively focus on verbal communication, as it also includes various non-verbal skills and responses. Therefore, option B accurately encapsulates the key characteristics of Discrete Trial Training.
