Behavior Assessment Flashcards

Which preference assessment method presents items one at a time and measures the client's approach response to each item?

Answer: Single stimulus assessment

The single stimulus (single item) preference assessment presents one item at a time and measures whether the client approaches or engages with it.

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

Answer: Percentage of trials in which each item was selected

In a PS assessment, each item's preference rank is determined by the percentage of trials in which it was chosen when presented against other items.

A free operant observation preference assessment is conducted by:

Answer: Allowing the client access to multiple items and recording time spent with each

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

The primary advantage of the Multiple Stimulus Without Replacement (MSWO) assessment over the paired stimulus assessment is that it:

Answer: Requires fewer trials to complete the preference hierarchy

The MSWO requires fewer trials than the paired stimulus assessment because items are removed after selection, reducing the total number of comparisons needed.

Preference assessments are conducted primarily to:

Answer: Identify stimuli that may serve as effective reinforcers

Preference assessments identify stimuli the individual is likely to prefer, which are then evaluated in reinforcer assessments to confirm their effectiveness as reinforcers.

A reinforcer assessment differs from a preference assessment in that a reinforcer assessment:

Answer: Tests whether identified preferred items actually increase behavior

A reinforcer assessment empirically tests whether a stimulus increases the future frequency of the behavior it follows, confirming its function as a reinforcer.

Which of the following is a limitation of using caregiver interviews to identify preferred stimuli?

Answer: Caregiver reports may not accurately reflect the client's current preferences

Caregiver interviews are an indirect method that relies on the caregiver's perception, which may be outdated or inaccurate regarding the client's current preferences.
