Understanding Preference Assessment Methods in Applied Behavior Analysis

What type of preference assessment is Olivia using?

Olivia is using the preference assessment method known as "b. Multiple Stimulus without Replacement."

Exploring Multiple Stimulus without Replacement (MSWO)

Multiple Stimulus without Replacement (MSWO) is a preference assessment method commonly used in applied behavior analysis. In this approach, a set of items is presented to the learner, and they are asked to choose one item from the array. Once the learner makes their choice, the selected item is not replaced immediately; instead, it is temporarily removed from the array. The remaining items are then rearranged, and the learner is again asked to choose from the reduced set of items. This process continues until all items have been chosen or until the learner's preferences have been adequately determined. Olivia's method aligns with MSWO because she removes the selected item temporarily without replacement before presenting the array again. This allows for a more precise assessment of the learner's preferences by gradually narrowing down their choices. Preference assessments are crucial in applied behavior analysis to identify reinforcers that motivate learners.
