ABA Measurement and Data Collection

Question 1

Which data collection method involves recording whether a behavior occurred at least once during an observation interval?

Accepted Answer

Partial interval recording

Answer

Partial interval recording scores a behavior as occurred if it happens at any point within the interval, regardless of duration.

Question 2

A BCBA wants to measure the time between the end of one response and the beginning of the next. What is this called?

Accepted Answer

Inter-response time (IRT)

Answer

Inter-response time (IRT) is the elapsed time between the end of one response and the onset of the next response.

Question 3

Which measurement dimension refers to the number of responses per unit of time?

Accepted Answer

Rate

Answer

Rate is frequency divided by time (responses per minute or hour), capturing both how often and how quickly behavior occurs.

Question 4

Momentary time sampling is BEST suited for measuring behaviors that are:

Accepted Answer

Ongoing or state behaviors

Answer

Momentary time sampling records whether a behavior is occurring at the exact moment the interval ends, making it ideal for continuous, state-like behaviors.

Question 5

A therapist records the time from the presentation of a discriminative stimulus to the beginning of the learner's response. This is called:

Accepted Answer

Latency

Answer

Latency measures the elapsed time between the onset of an antecedent stimulus and the start of the target response.
