In Whole-Interval Time Sampling, when is the target behavior recorded positively?

In Whole-Interval Time Sampling, the target behavior is recorded positively throughout the entire interval. This method requires the observer to note whether the behavior occurs continuously during the designated time period. Specifically, for a behavior to be marked as having occurred, it must be present for the full duration of the interval, not just at the beginning or at some point during it. This approach aims to capture instances where the behavior is sustained, allowing practitioners to understand the context and duration of the behavior more effectively.

In this sampling method, even if the target behavior happens only once or is prompted by someone else, it would not meet the criteria necessary for positive recording unless it is persistent throughout the entire interval.
