Which preference assessment presents all items on the first trial and excludes chosen items from subsequent trials?

• A. Mswo
• B. Paired-stimulus assessment
• C. Multiple stimulus with replacement
• D. Single stimulus assessment

Answer: (A)

This item tests how a preference assessment can quickly yield a full rank order by updating the set after each choice. In a multiple-stimulus without replacement approach, all items are shown on the first trial. The individual picks one item, and that item is removed from consideration for all subsequent trials. The remaining items are presented again, and the process repeats until every item has been chosen. This generates a complete ranking from most to least preferred in relatively few trials, and it prevents the same item from appearing again after it’s been selected, which helps reveal true relative preferences. The other methods don’t fit this description. Paired-stimulus presents items two at a time rather than listing all items initially. Multiple-stimulus with replacement keeps items in the pool after a selection, so chosen items can reappear later. Single-stimulus presents one item at a time and doesn’t automatically produce a full rank order within a single session or remove chosen items from future trials.
