Which data collection method involves recording whether a behavior occurs during successive time intervals?

• A. Interval recording
• B. Duration recording
• C. ABC data
• D. Event recording

Answer: (A)

Recording whether a behavior occurs during successive time intervals captures presence or absence within each defined time block, giving a view of patterns over time without tallying every single instance. This method is especially useful when behaviors happen irregularly or quickly, because you can divide observation into manageable chunks and note if the behavior occurred at least once in each interval. Over many intervals, you can compute the proportion of intervals with the behavior to see trends. This approach differs from other methods: event recording counts each occurrence as it happens and focuses on frequency of every instance; duration recording measures how long the behavior lasts; ABC data records antecedents and consequences to understand function rather than simply track when the behavior occurs. Interval recording may include partial-interval, whole-interval, or momentary time sampling, depending on how you define and score each interval.
