In a multiple stimulus with replacement (MSW) preference assessment, what happens to chosen stimuli?

In a multiple stimulus with replacement (MSW) preference assessment, chosen stimuli are replaced back into the array after selection. This approach allows for the evaluation of preferences in a way that maintains the availability of stimuli for further selection. By replacing chosen items, the assessment can gauge not just the initial choice but also the consistency of preference across multiple trials. If a participant often selects the same item when it’s repeatedly presented, it indicates a stronger preference for that stimulus.

This method provides valuable insights into the individual’s preferences and ensures that all items can be assessed multiple times, which contributes to a more reliable understanding of what items motivate or engage the individual. This aspect is crucial in behavior analysis and treatment planning, as it helps to identify reinforcing stimuli that can be used effectively in interventions.
