Multiple-Stimulus With Replacement
Also called: MSW, multiple stimulus with replacement preference assessment
Definition
A preference assessment in which an array is presented, the person selects an item, the selected item is returned to the array and the unselected items are replaced with new ones, and the array is presented again. It identifies the top preference quickly but gives less information about the ranking of the rest.
In plain language
Lay out several items and let the person pick. The picked item stays; the others are swapped for new ones. Fast at finding the favorite, weak at ranking the rest.
Example
The learner keeps choosing the toy car each round while the other items rotate. The car is clearly the top preference.
Not multiple-stimulus with replacement
The chosen item is removed and the rest re-presented. That is without replacement.
