Difficulty: easy. Skill: recognize. Type: concept discrimination.
A BCBA wants to measure how long a learner remains out of seat after each occurrence. Which measurement system best matches this goal?
Correct answer
Duration measures how long a behavior occurs. The question asks how long the learner remains out of seat.
Frequency counts occurrences but not how long they last.
Latency measures time from a stimulus to response onset.
Momentary time sampling estimates occurrence at specific moments, not exact episode length.
