Once you have developed a task analysis, you should not change the sequence of steps, add steps, or remove steps in the analysis. This invalidates the task analysis.
a.Every step in a behavior chain (except the first and last behaviors) serves two functions: an SD for the subsequent step and as a conditioned reinforcer for the preceding step.
b. A behavior chain with a limited hold results in performance that is both accurate and fluent.
c.Once you have developed a task analysis, you should not change the sequence of steps, add steps, or remove steps in the analysis. This invalidates the task analysis.
d.In order to construct a task analysis, it is acceptable and valid to perform the behavior yourself and write down the steps to the skill ask you perform them.
