Preference Assessment Methods in ABA Therapy

What is the term used when a child chooses an item during a preference assessment but the item is not included in the subsequent choices?

The term used for this scenario is:

a. Multiple stimulus w/o replacement (MSWO)

b. Multiple stimulus w/ replacement (MSW)

c. Paired choice

d. Free operant

When a child chooses an item during a preference assessment but the item is not included in the subsequent choices, the correct term for this situation is Multiple stimulus w/o replacement (MSWO).

In MSWO preference assessment, items are presented one at a time without replacement. This means that once an item is chosen, it is removed from the choices for the rest of the assessment. The chosen item is not replaced back into the choices for subsequent assessments, distinguishing it from Multiple stimulus w/ replacement (MSW).

Choosing the item and continuing the assessment without it is not an example of paired choice or free operant in the context of preference assessment.
