Two variations of multiple-stimulus preference assessments are abbreviated as what?

• A. MSW, MSWO
• B. MSWO, MSW
• C. Paired-stimulus, Free-operant
• D. Multiple-stimulus with replacement

Answer: (A)

Multiple-stimulus preference assessments come in two common variations distinguished by what happens to the stimuli after a choice. If the chosen item is returned to the array after each selection, it’s with replacement, abbreviated MSW. If the chosen item is removed from the array, it’s without replacement, abbreviated MSWO. The pair MSW, MSWO captures these two variations, with MSW typically referring to with replacement and MSWO to without replacement. The other options describe different procedures or use different naming, so they don’t match the requested pair of abbreviations.
