What is the correct order of the four steps in discrete trial training (DTT)?

• A. cue or instruction (prompt); response; consequence/reinforcement; intertrial interval (2-5 sec)
• B. response; cue or instruction (prompt); intertrial interval; consequence/reinforcement
• C. cue or instruction (prompt); intertrial interval; response; consequence/reinforcement
• D. intertrial interval (2-5 sec); cue or instruction (prompt); response; consequence/reinforcement

Answer: (A)

In discrete trial training, each trial follows a clear sequence: present a cue or instruction, the learner responds, deliver the consequence or reinforcement, and then use a brief intertrial interval before the next trial. This order establishes the antecedent that evokes the desired response, makes the response the focal behavior to be measured, reinforces the correct response to strengthen it, and then pauses briefly to reset and prepare for the next opportunity. Why this order fits best: the cue (or prompt) sets up the specific situation where the learner is expected to respond in a defined way. The response is then observed and tied to the subsequent consequence, so reinforcement directly strengthens the exact behavior that occurred. The short intertrial interval helps separate trials, reducing carryover from one trial to the next and maintaining the learner’s focus for accurate discrimination on future trials. If reinforcement were delivered before the response, or if the intertrial interval happened before presenting the cue, the trial wouldn’t be a clean, discrete unit, and learning would be confounded by timing and contingencies.
