Question 2

In a paired stimulus (PS) preference assessment, a hierarchy is determined by calculating the:

Answer

Free operant observations allow the client unrestricted access to an array of items and use duration of engagement as the index of preference.

Accepted Answer

Requires fewer trials to complete the preference hierarchy
