RBT Discrete Trial Training

Question 1

What are the basic components of a discrete trial?

Accepted Answer

Antecedent, behavior, consequence, inter-trial interval

Answer

A discrete trial consists of the antecedent (SD or instruction), the learner's behavior (response), the consequence (reinforcement or error correction), and an inter-trial interval (brief pause before the next trial). This structured format allows for repeated practice.

Question 2

What is the purpose of the inter-trial interval (ITI) in DTT?

Accepted Answer

To provide a clear separation between trials so the learner can distinguish between successive learning opportunities

Answer

The ITI provides a clear break between trials, helping the learner distinguish one learning opportunity from the next. It also allows the instructor to prepare materials and data sheets for the next trial and prevents trial-to-trial confusion.

Question 3

During DTT, when should the RBT deliver reinforcement?

Accepted Answer

Immediately after the learner gives a correct response

Answer

Reinforcement should be delivered immediately after a correct response during DTT. Immediate reinforcement strengthens the connection between the correct response and the consequence, making the behavior more likely to occur again.

Question 4

In DTT, what does the term 'massed trials' refer to?

Accepted Answer

Repeated presentations of the same target in consecutive trials

Answer

Massed trials involve presenting the same target or SD repeatedly across consecutive trials. This concentrated practice helps the learner acquire a new skill quickly by providing many opportunities to practice the same response.

Question 5

What is the difference between massed and distributed (interspersed) trials?

Accepted Answer

Massed trials repeat the same target consecutively; distributed trials mix different targets within a set

Answer

Massed trials present the same target repeatedly (e.g., 'touch red, touch red, touch red'), while distributed or interspersed trials mix the target with other known or unknown targets (e.g., 'touch red, touch blue, touch red, touch green').
