ABA- Discrete Trial Training
Discrete Trial Training(DTT) is a structured teaching method used in ABA that is used to help people with Autism, DTT involves breaking down a skill into small, manageable steps and teaching them one at a time.
Discrete trial training is a key method that is used in ABA. Discrete trial training involves 3 main components-
- Discriminative stimulus(SD)- Discriminative stimulus is a clear instruction or cue given by the therapist to the child.
- Child’s response or Prompt- The Child’s reaction to the SD and use of prompt by the therapist if needed to guide the correct response.
- Reinforcement or correction- if the response is correct immediate reinforcement is given to reinforce the behavior. If the response is not right, in that case, correction is applied.
The first step for discrete trial training is to deliver a good and clear SD; in case of a correct response, immediate reinforcement is given to encourage the behavior. In case of an incorrect response, correction is applied.
Two key concepts discussed in this video are:
- Prompts: Prompts are additional cues or support from the therapist to guide the child towards the desired behavior.
- Reinforcements: Reinforcement is the strengthening of a particular behavior; varying the type and frequency of reinforcement helps maintain the child’s motivation and learning process.
