Which preference assessment presents multiple items simultaneously to obtain a ranking of items?

• A. Single-item approach
• B. Multiple-stimulus
• C. Paired-stimulus
• D. MSWO

Answer: (B)

Offering several potential reinforcers at the same time lets you directly compare them and build a rank order of preference from the choices made. When multiple items are presented together, the learner’s selections across trials reveal which items are most and least preferred, allowing you to derive a hierarchy efficiently. This simultaneous presentation is the hallmark of the multiple-stimulus approach, and it’s especially effective for producing a full ranking of items. The more specific variant that uses a no-replacement rule after each choice still fits this idea, but in general, presenting multiple items at once to obtain a ranking aligns with the multiple-stimulus method.
