Ms. March is teaching Matthew to do his laundry. She has written a task analysis for
doing laundry, which consists of 36 steps. She conducted an initial assessment to
identify which steps Matthew could already do, and she discovered that the only step he
can presently do independently is to open the lid to the washer. She decides to use total
task presentation as her method of teaching this complex chain of behaviors, using a
least-to-most prompting strategy. What might be one disadvantage to this procedure?
a. This procedure is likely to make each training session quite long.
b. Matthew may become confused with the sequence of the task because the teaching
procedure involves having him do the last step, then the last two steps, and so on.
c. Because Matthew’s present behavior will be placed on extinction until he emits a new
behavior that is closer to the terminal behavior, he will likely become very frustrated.
d. All of these are reasonable concerns given the teaching context.
Which of the following is considered a limitation in the use of a multiple treatment
reversal design?
A. Sequence effects
B. Observer drift
C. Rapid alternation effects
D. Variability
