RBT Task Analysis and Chaining

Question 1

What is a task analysis in the context of ABA?

Accepted Answer

The process of breaking a complex skill into a sequence of smaller, observable, teachable steps

Answer

A task analysis breaks a multi-step skill (e.g., handwashing, making a sandwich) into a series of discrete, observable steps that can be taught and measured individually, making complex skills achievable for learners who cannot acquire them all at once.

Question 2

In FORWARD chaining, where does teaching begin?

Accepted Answer

The first step in the task analysis

Answer

Forward chaining teaches steps in order from first to last. The learner masters step 1 independently before step 2 is introduced. The therapist completes all remaining steps until the learner chains forward through the entire sequence.

Question 3

In BACKWARD chaining, which step does the learner initially learn to perform independently?

Accepted Answer

The last step in the task analysis, with the therapist completing all prior steps

Answer

In backward chaining, the therapist completes all steps up to the final one, and the learner is taught only the last step. This ensures the learner always experiences the natural reinforcer (task completion) immediately after their response, which is a key motivational advantage.

Question 4

Which chaining method involves the learner practicing the ENTIRE sequence during every teaching session, with prompts provided for any steps not yet mastered?

Accepted Answer

Total task chaining

Answer

Total task chaining has the learner attempt every step in the task analysis during each trial, with the RBT providing prompts (as needed) for steps not yet performed independently. This approach maximizes exposure to the full chain and is often preferred for learners who can handle the entire sequence with support.

Question 5

Before selecting and implementing a chaining procedure, an RBT should first ensure that:

Accepted Answer

A baseline probe across all steps of the task analysis has been completed

Answer

A baseline probe assesses which steps the learner can already perform independently before instruction begins. This data informs which chaining method to select, where to begin instruction, and provides a comparison point for measuring progress.
