RBT Discrete Trial Training 2

Question 1

What is a 'distractor' in the context of DTT?

Accepted Answer

A non-target stimulus presented alongside the target stimulus to require discrimination

Answer

In DTT, distractors are non-target stimuli presented alongside the correct target stimulus (e.g., showing a picture of a dog and a car when asking 'point to the dog'). The learner must discriminate between the target and distractors to respond correctly.

Question 2

How should the RBT arrange the teaching environment for DTT?

Accepted Answer

In a structured setting with minimal distractions, materials organized, and the learner positioned to attend to the instructor

Answer

DTT works best in a structured environment with minimal distractions. Materials should be organized and ready, and the learner should be positioned to attend to the instructor. This controlled setting allows for clear presentation of stimuli and efficient trial delivery.

Question 3

What is the purpose of rotating reinforcers during DTT sessions?

Accepted Answer

To prevent satiation and maintain the learner's motivation throughout the session

Answer

Rotating reinforcers prevents satiation (the learner getting tired of the same reinforcer) and maintains motivation. Using a variety of preferred items keeps the learner engaged and willing to work throughout the session.

Question 4

An RBT is teaching color identification using DTT. The field size is 3 (three color cards on the table). What does 'field size' mean?

Accepted Answer

The number of stimulus choices presented to the learner on each trial

Answer

Field size refers to the number of stimulus choices presented simultaneously during a trial. A field of 3 means three items are placed before the learner, and they must select the correct one. Increasing field size increases discrimination difficulty.

Question 5

What is the purpose of 'mixing' known and unknown targets during DTT?

Accepted Answer

To build confidence through known targets while practicing unknown ones, and to promote discrimination

Answer

Mixing known (mastered) targets with unknown (acquisition) targets maintains motivation through frequent success, provides opportunities to maintain mastered skills, and promotes discrimination between different stimuli.
