Which preference assessment involves presenting a single item at a time and recording the duration of interaction with each item?

• A. Single-item duration
• B. Free-operant preference assessment
• C. MSWO
• D. Paired-stimulus

Answer: (A)

This item tests preference by measuring how long someone will interact with an item when it is presented alone. In a single-item duration approach, you show one item at a time and record the total time the person engages with it during a fixed trial. The idea is that longer interaction time indicates higher preference for that item. This provides a direct, time-based readout of each item’s appeal. Other methods involve items being available together or making choices between items, rather than isolating one item at a time. For example, free-operant allows multiple items to be present and tracks engagement across the session, not the duration with a single item. Multiple-stimulus without replacement presents several items simultaneously and records which one is chosen, removing the rest after selection. Paired-stimulus presents two items at a time and records which one is chosen. Since those approaches don’t present a single item in isolation with a duration measure, they don’t fit the described procedure.
