WHAT IS DTT?

DTT is a structured, systematic approach used in ABA therapy to teach specific skills, often used with children, especially those with autism spectrum disorder (ASD).

Discrete trials:

A discrete trial is a single, structured teaching interaction that includes:

Antecedent (Prompt):

The teacher or therapist gives a clear instruction (e.g., "Touch the red button").

Response:

The learner reacts to the instruction (e.g., "Touches the red button").

Consequence (Reinforcement or Correction):

If the response is correct the learner gets a reward if incorrect the teacher or therapist guides the learner with a prompt or correction.

Prompting and Fading:

Prompts help the learner at first but are gradually faded as they master the skill.

Data Collection:

ABA therapist track each learner's progress throughout data which helps adjust teaching methods as needed.

Clear, concise Instructions:

The instructions are simple and the point is to avoid confusion and frustration.

Repetition:

Learners repeat the trials multiple times to improve and reinforce the behavior.
