Discrete Trial Teaching Methods Flashcards

A client is being taught to identify letters using DTT. The RBT presents the letter 'A' and gives the instruction 'What letter?' The client says 'B.' The RBT immediately says 'That's the letter A,' then waits 3 seconds and re-presents the trial. Which error correction procedure is this?

Answer: Model error correction with transfer trial

In model error correction with a transfer trial, the instructor models the correct response after an error, then re-presents the SD after a brief pause to give the client an opportunity to respond correctly.

What does 'prompt dependency' mean in the context of DTT skill acquisition?

Answer: The client's reliance on prompts to respond, failing to develop independent responding without the prompt

Prompt dependency occurs when a client consistently requires a prompt to respond and does not develop independent responding. It results from insufficient prompt fading or delivery of reinforcement for prompted rather than independent responses.

In a DTT program, a 'mastery criterion' of '80% correct across 3 consecutive sessions' means:

Answer: The client scores 80% or higher in 3 sessions in a row before the target can be considered mastered

A mastery criterion of 80% across 3 consecutive sessions requires the client to score 80% or above in each of three consecutive sessions, ensuring that performance is stable and reliable before the target is considered mastered.

What is 'blocking' in the context of DTT error prevention?

Answer: Physically or gestually preventing a client from selecting an incorrect response without providing the correct answer

Blocking involves physically or gestually preventing the client from completing an incorrect response (e.g., gently guiding the hand away from the wrong choice) without providing reinforcement or the correct answer, used as an errorless or error-prevention strategy.

An RBT is teaching a client to identify colors. The client consistently selects the card on the left side of the table regardless of what is placed there. What error pattern is this?

Answer: Position bias — the client is responding to position rather than to the color SD

Position bias occurs when a client responds based on the position of items in the array rather than to the discriminative stimulus (the color name). This indicates a failure of appropriate stimulus control.

Which component of the discrete trial contains information about whether the client's response was appropriate and what the consequence will be?

Answer: The consequence (reinforcement or error correction)

The consequence is the component of the discrete trial that follows the client's response and provides information about whether the response was correct (by delivering reinforcement) or incorrect (by delivering error correction).
