Which preference assessment presents all items on each trial and does not return selected items to the array?

• A. Free-operant
• B. Single-item approach
• C. Paired-stimulus
• D. Multiple-stimulus without replacement

Answer: (D)

This question tests how different preference assessments handle item presentation and replacement. In a multiple-stimulus without replacement approach, all available items are shown on every trial, and once the learner selects one item, that item is not put back into the array for future trials. This means the set of items shrinks over trials, allowing a rank order to emerge from the sequence in which items are chosen. It’s efficient for deriving a clear hierarchy because each trial pits the remaining options directly against each other, and the repeated removal of selected items creates direct comparisons across items. Other methods don’t fit this pattern: presenting one item at a time, or presenting only two items per trial, or allowing items to be returned after selection, do not involve all items on each trial with no replacement.
