Which method relies on counting how frequently a behavior occurs during a defined period to obtain a frequency measure?

• A. Interval recording
• B. Narrative recording
• C. Ratings Recording
• D. Event Recording

Answer: (D)

Counting how often a behavior occurs within a defined period is event recording. In this approach, the observer marks each discrete instance of the target behavior as it happens, producing a raw frequency count that can be converted into a rate by dividing by the observation time. It's ideal for discrete, countable behaviors (like the number of times a child raises a hand or the number of vocalizations) and relies on a clear, operational definition to ensure each occurrence is counted consistently. This differs from interval recording, which notes whether the behavior occurred at least once during each interval, potentially missing multiple occurrences within one interval; it also differs from ratings recording, which assigns a subjective score rather than a literal count, and from narrative recording, which describes behavior in words rather than counting it. For accurate results, define what counts as a separate occurrence, use a reliable observation period, and consider inter-observer reliability.
