Question 1

What is the primary advantage of using momentary time sampling over whole interval recording?

Accepted Answer

It is less affected by observer fatigue during long observation periods

Answer

Momentary time sampling only requires observing the client at the end of each interval, making it more practical for lengthy sessions.

Question 2

Which of the following best defines 'celeration' in the context of Standard Celeration Chart data analysis?

Accepted Answer

The rate of change in behavior frequency over time

Answer

Celeration describes how quickly behavior frequency is accelerating or decelerating across time on a Standard Celeration Chart.

Question 3

A behavior consultant notices high variability in baseline data. What is the recommended decision before implementing an intervention?

Accepted Answer

Continue baseline until a stable trend is established

Answer

A stable baseline is required to establish a valid comparison point; high variability makes it difficult to detect treatment effects.

Question 4

Inter-response time (IRT) is best used to measure which behavioral characteristic?

Accepted Answer

The time between consecutive responses

Answer

IRT captures the elapsed time between the end of one response and the start of the next, useful for spacing or fluency goals.

Question 5

Which type of IOA is most appropriate when a behavior has a very low rate of occurrence?

Accepted Answer

Occurrence-only IOA

Answer

Occurrence-only IOA focuses agreement calculations on intervals where at least one observer recorded the behavior, preventing inflated agreement due to shared non-occurrences.
