RBT - Registered Behavior Technician Skill Acquisition Programs 1

Question 1

When using backward chaining to teach a multi-step tooth-brushing routine, which step does the RBT teach first?

Accepted Answer

The last step: rinsing and spitting

Answer

Backward chaining begins instruction at the final step of the task analysis. The RBT completes all preceding steps and then prompts/reinforces only the last step, so the learner always experiences task completion and the natural reinforcer at the end.

Question 2

An RBT reinforces a child for saying 'buh', then 'ba', then 'ball' as successive attempts improve. Which skill acquisition procedure is being used?

Accepted Answer

Shaping

Answer

Shaping involves reinforcing successive approximations of a target behavior. Each closer attempt to the final response is reinforced while previous, less accurate forms are placed on extinction.

Question 3

A learner correctly sorts objects by color during tabletop sessions but cannot sort the same colors when given classroom supplies. This breakdown is best described as:

Accepted Answer

Failure to generalize across stimuli

Answer

Stimulus generalization occurs when a skill transfers to new materials, settings, or people. When this fails, the learner's response is under narrow stimulus control — only the training stimuli evoke the behavior.

Question 4

In total task chaining, how does the RBT present the steps of a task analysis during each teaching session?

Accepted Answer

All steps every session, prompting as needed on steps not yet independent

Answer

Total task chaining requires the learner to attempt every step of the task analysis in each session. The RBT provides whatever level of prompting is needed for non-mastered steps, allowing practice of the full chain on every trial.

Question 5

After a learner touches the wrong picture on a receptive identification trial, the RBT immediately models the correct response, prompts the learner to touch the correct picture, praises the prompted response, and then re-presents the original SD. This sequence is an example of:

Accepted Answer

A 4-step error correction procedure

Answer

The 4-step error correction procedure consists of: (1) Model — show the correct response; (2) Lead — prompt the learner through it; (3) Reinforce the prompted correct response; (4) Repeat — re-present the original discriminative stimulus to check for learning.
