Task-analyzed Chaining Procedures

Question 1

Define task-analyzed chaining procedures

Answer 1

Chaining is a teaching procedure by which a specific sequence of responses is taught, such that the completion of the previous responses serves as the Sd for the next response.

Most often used when teaching a complex behavior (e.g. getting dressed) in which the steps are always performed in the same order.

Question 2

Define Task Analysis

Answer 2

Set a successive component steps, in small, teachable units, that comprise a complex behavior.

i.e.
Washing Hands:
1) turn on water. 2) wet both hands. 3) pump soap. 4) scrub both hands. 5) rinse both hands. 6) turn off water. 7) dry both hands.

Question 3

Define Forward Chaining

Answer 3

Training the 1st step in the chain to fluency while prompting all successive steps. Successive steps are targeted for acquisition as the previous step reaches fluency.

i.e.
Washing Hands:
Target acquisition for “turning on the water” while fully prompting remaining steps. When tuning on the water is fluent, allow client to independently turn on water, target acquisition for “wet hands” and fully prompt remaining steps. Continue pattern until all steps fluent.

Question 4

Define Backward Chaining

Answer 4

Training the last step in a chain to fluency while prompting all preceding steps. Preceding steps are targeted for acquisition as the successive step reaches fluency.

i.e.
Washing Hands:
Fully Prompt all steps until target acquisition step of “dry hands”. When drying hands is fully fluent, fully prompt all steps until target acquisition step of “turn off water”, and allow dry hands to be done independently. Continue pattern until all steps fluent.

Question 5

Define Total Task Presentation

Answer 5

Training all steps in the chain at the same time.

i.e.
Washing Hands
All steps are targeted for acquisition at the same time, with level of prompting varying from step to step.
