ABA Research, Analysis, and Intervention 4

Question 1

A behavior analyst wants to evaluate the social validity of an intervention. The most appropriate source of information is:

Accepted Answer

Ratings from the consumer, caregivers, and other relevant stakeholders

Answer

Social validity is assessed by soliciting opinions from consumers, caregivers, and the community about goals, procedures, and outcomes.

Question 2

Which of the following best describes the concept of a 'bidirectional' functional relationship in behavior analysis?

Accepted Answer

A relationship where manipulating the independent variable changes the dependent variable in a predictable, reproducible way

Answer

A bidirectional functional relationship means the dependent variable reliably changes when the independent variable is introduced or removed, demonstrating experimental control.

Question 3

When conducting interval recording, partial-interval recording tends to __________ the true frequency of behavior, while whole-interval recording tends to __________.

Accepted Answer

Overestimate; underestimate

Answer

Partial-interval recording scores an interval if behavior occurs at any point (inflates estimates), while whole-interval requires behavior throughout (deflates estimates).

Question 4

A BCBA uses a paired-stimulus preference assessment and finds that Item A is chosen 95% of the time over all other items. To confirm Item A functions as a reinforcer, the next step is:

Accepted Answer

Conduct a reinforcer assessment by contingently delivering Item A for a target response and measuring response rate change

Answer

A reinforcer assessment verifies that the preferred item actually strengthens behavior by demonstrating increased response rates when it is delivered contingently.

Question 5

In single-case research, the term 'replication' within the same study (i.e., intra-subject replication) refers to:

Accepted Answer

Observing the same behavior change repeat across phases or tiers within the same participant or study

Answer

Intra-subject replication demonstrates the reliability of a functional relationship by showing that behavior changes consistently whenever the independent variable is applied or removed.
