A DTT can be broken down into the 5 steps as follows:
1. Antecedent Stimulus. This is the stimulus being provided to the learner that is used to signal a response; the discriminative stimulus (SD).
2. Prompt. This can be verbal, gestural, physical, model, or positional. It is typically based on the learner’s skill repertoire. Based on our specific learner’s history of responding correctly to verbal prompts, their imitative repertoire, as well as the type of relations we are teaching, we will be using both verbal and gestural prompts.
3. Response. There is only 1 correct response, and it must be delivered within 5 seconds of presentation of the stimulus.
4. Consequence. Correct answers will result in delivery of reinforcement.
5. Inter-trial interval. This is the time between delivery of reinforcement and presentation of the next stimulus. It should only take 2-3 seconds, and this time should be used to mark down data collection.
