What refers to procedures used to determine the items that a person prefers?

The procedures used to determine the items that a person prefers are known as a stimulus preference assessment. This method is crucial in applied behavior analysis (ABA) as it helps identify what items or activities may serve as effective reinforcers for individuals, especially those with autism. By understanding individual preferences, practitioners can tailor interventions to be more engaging and motivating, thereby increasing the likelihood of positive behavior change.

Stimulus preference assessments often involve various strategies, such as asking the individual about their preferences, observing their choices in a free environment, or using more structured approaches like forced-choice assessments. This systematic identification of preferences informs treatment plans and daily interventions, making engagement more effective.

In contrast, other terms listed, such as functional behavior assessment and behavioral assessment, focus on understanding the underlying reasons for specific behaviors or assessing a wide range of behavioral issues, rather than specifically identifying preferences for tangible items or activities. Baseline refers to the initial measurement of behavior before any intervention is implemented and does not pertain to preference determination.
