Behavior AssessmentDifficulty 2/5
An RBT presents six toys at once. The learner picks one, plays with it, and the RBT removes that toy before presenting the remaining five. This continues until all toys are chosen. Which assessment is this?
- AMultiple-stimulus-without-replacement (MSWO)
- BFree-operant preference assessment
- CFunctional analysis
- DPaired-stimulus preference assessment
Show answer and rationale
Correct: A. Presenting an array, removing the chosen item, and re-presenting the rest is multiple-stimulus-without-replacement. The order of selection gives a preference ranking.
- D — Paired-stimulus presents exactly two items at a time.
- B — Free-operant leaves all items available and records engagement time.
- C — A functional analysis manipulates conditions to test the function of problem behavior, not preference.
