The method that involves marking an interval several times to assess a behavior's occurrence is partial interval recording. In this approach, observers record whether a behavior occurs at any point during specified intervals. This technique is particularly useful for behaviors that are expected to occur frequently and can provide a conservative estimate of how often a behavior takes place during the interval.

For instance, if a 10-second interval is used, the observer may note if the behavior occurs at any moment within those 10 seconds. This way of data collection helps in capturing bursts of behavior, even if they are temporary. It is effective for evaluating behaviors that may not last the entire duration of the intervals being observed, indicating that the behavior might have occurred in any part of that interval.

Other methods, such as whole interval recording or momentary time sampling, operate under different rules regarding how behavior occurrence is noted, differing significantly from the approach used in partial interval recording. Hence, understanding the methodology behind partial interval recording emphasizes its unique capability to capture transient behaviors over time.
