Question

Which of the following preference assessments usually takes the longest to administer?

A. Free Operant
B. Multiple Stimulus With Replacement
C. Paired Stimulus

Answer 1

The Multiple Stimulus With Replacement (MSWR) assessment usually takes the longest to administer.

Step-by-step explanation:

The preference assessment that usually takes the longest to administer is the Multiple Stimulus With Replacement (MSWR) assessment.

In an MSWR assessment, the student is presented with multiple items at once and is allowed to choose one. After the choice is made, the chosen item is replaced, and the student is presented with the remaining items to choose from again. This process continues until all items have been chosen.

Due to the nature of this assessment, where multiple items are presented and replaced, it takes more time compared to other preference assessments such as the Free Operant or Paired Stimulus assessments.

Answer 2

C. Paired Stimulus

The Paired Stimulus preference assessment usually takes the longest to administer because it involves presenting each item paired with every other item, requiring many trials.

Step-by-step explanation:

Among the preference assessments mentioned, the Paired Stimulus usually takes the longest to administer. This is because in a Paired Stimulus assessment, also known as paired-choice assessment, each item or stimulus is presented to the individual paired with every other item. Therefore, if you have a number of items, each pairing takes a certain amount of time and there can be many pairings. This method can be time-consuming especially with more items, as it requires a significant number of trials to determine preference hierarchy.

In contrast, the Free Operant assessment involves observing what an individual engages with the most when they have free access to multiple stimuli, which doesn't necessarily take as long. The Multiple Stimulus With Replacement (MSW) is also generally quicker than the Paired Stimulus because it involves presenting all of the stimuli together and replacing the chosen stimulus to be selected again, which involves fewer iterations than the pairwise comparisons.
